If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. + +On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary.

If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". + +## Wildcards + + The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + + You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +#### Web Inspector Colors + + Colors are also enabled on "Web Inspectors" that understand the `%c` formatting + option. These are WebKit web inspectors, Firefox ([since version + 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) + and the Firebug plugin for Firefox (any version). + + Colored output looks something like: + + ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example _stdout.js_: + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`?

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`?

Without much thought, you run `testify --harmony spec tests.js`. + +It doesn't work. After digging around for a bit, you realize this produces a [`process.argv`](http://nodejs.org/docs/latest/api/process.html#process_process_argv) of: + +`['node', '/usr/local/bin/test', '--harmony', 'spec', 'tests.js']` + +Crap.

There + is no way at this time to continue a glob search after aborting, but + you can re-use the statCache to avoid having to duplicate syscalls. +* `cache` Convenience object. Each field has the following possible + values: + * `false` - Path does not exist + * `true` - Path exists + * `'FILE'` - Path exists, and is not a directory + * `'DIR'` - Path exists, and is a directory + * `[file, entries, ...]` - Path exists, is a directory, and the + array value is the results of `fs.readdir` +* `statCache` Cache of `fs.stat` results, to prevent statting the same + path multiple times. +* `symlinks` A record of which paths are symbolic links, which is + relevant in resolving `**` patterns. +* `realpathCache` An optional object which is passed to `fs.realpath` + to minimize unnecessary syscalls. It is stored on the instantiated + Glob object, and may be re-used. + +### Events + +* `end` When the matching is finished, this is emitted with all the + matches found. If the `nonull` option is set, and no match was found, + then the `matches` list contains the original pattern. The matches + are sorted, unless the `nosort` flag is set. +* `match` Every time a match is found, this is emitted with the specific + thing that matched. It is not deduplicated or resolved to a realpath. +* `error` Emitted when an unexpected error is encountered, or whenever + any fs error occurs if `options.strict` is set. +* `abort` When `abort()` is called, this event is raised. + +### Methods + +* `pause` Temporarily stop the search +* `resume` Resume the search +* `abort` Stop the search forever + +### Options + +All the options that can be passed to Minimatch can also be passed to +Glob to change pattern matching behavior. Also, some have been added, +or have glob-specific ramifications. + +All options are false by default, unless otherwise noted. + +All options are added to the Glob object, as well. + +If you are running many `glob` operations, you can pass a Glob object +as the `options` argument to a subsequent operation to shortcut some +`stat` and `readdir` calls. At the very least, you may pass in shared +`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that +parallel glob operations will be sped up by sharing information about +the filesystem. + +* `cwd` The current working directory in which to search. Defaults + to `process.cwd()`. +* `root` The place where patterns starting with `/` will be mounted + onto. Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix + systems, and `C:\` or some such on Windows.) +* `dot` Include `.dot` files in normal matches and `globstar` matches. + Note that an explicit dot in a portion of the pattern will always + match dot files. +* `nomount` By default, a pattern starting with a forward-slash will be + "mounted" onto the root setting, so that a valid filesystem path is + returned. Set this flag to disable that behavior. +* `mark` Add a `/` character to directory matches. Note that this + requires additional stat calls. +* `nosort` Don't sort the results. +* `stat` Set to true to stat *all* results. This reduces performance + somewhat, and is completely unnecessary, unless `readdir` is presumed + to be an untrustworthy indicator of file existence. +* `silent` When an unusual error is encountered when attempting to + read a directory, a warning will be printed to stderr. Set the + `silent` option to true to suppress these warnings. +* `strict` When an unusual error is encountered when attempting to + read a directory, the process will just continue on in search of + other matches. Set the `strict` option to raise an error in these + cases. +* `cache` See `cache` property above. Pass in a previously generated + cache object to save some fs calls. +* `statCache` A cache of results of filesystem information, to prevent + unnecessary stat calls. While it should not normally be necessary + to set this, you may pass the statCache from one glob() call to the + options object of another, if you know that the filesystem will not + change between calls. (See "Race Conditions" below.) +* `symlinks` A cache of known symbolic links. You may pass in a + previously generated `symlinks` object to save `lstat` calls when + resolving `**` matches. +* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead. +* `nounique` In some cases, brace-expanded patterns can result in the + same file showing up multiple times in the result set. By default, + this implementation prevents duplicates in the result set. Set this + flag to disable that behavior. +* `nonull` Set to never return an empty set, instead returning a set + containing the pattern itself. This is the default in glob(3). +* `debug` Set to enable debug logging in minimatch and glob. +* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets. +* `noglobstar` Do not match `**` against multiple filenames. (Ie, + treat it as a normal `*` instead.) +* `noext` Do not match `+(a|b)` "extglob" patterns. +* `nocase` Perform a case-insensitive match. Note: on + case-insensitive filesystems, non-magic patterns will match by + default, since `stat` and `readdir` will not raise errors. +* `matchBase` Perform a basename-only match if the pattern does not + contain any slash characters. That is, `*.js` would be treated as + equivalent to `**/*.js`, matching all js files in all directories. +* `nodir` Do not match directories, only files. (Note: to match + *only* directories, simply put a `/` at the end of the pattern.) +* `ignore` Add a pattern or an array of glob patterns to exclude matches. + Note: `ignore` patterns are *always* in `dot:true` mode, regardless + of any other settings. +* `follow` Follow symlinked directories when expanding `**` patterns. + Note that this can result in a lot of duplicate references in the + presence of cyclic links. +* `realpath` Set to true to call `fs.realpath` on all of the results. + In the case of a symlink that cannot be resolved, the full absolute + path to the matched entry is returned (though it will usually be a + broken symlink) +* `absolute` Set to true to always receive absolute paths for matched + files. Unlike `realpath`, this also affects the values returned in + the `match` event. +* `fs` File-system object with Node's `fs` API. By default, the built-in + `fs` module will be used. Set to a volume provided by a library like + `memfs` to avoid using the "real" file-system. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between node-glob and other +implementations, and are intentional. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.3, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +Note that symlinked directories are not crawled as part of a `**`, +though their contents may match against subsequent portions of the +pattern. This prevents infinite loops and duplicates and the like. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then glob returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. + +### Comments and Negation + +Previously, this module let you mark a pattern as a "comment" if it +started with a `#` character, or a "negated" pattern if it started +with a `!` character. + +These options were deprecated in version 5, and removed in version 6. + +To specify things that should not match, use the `ignore` option. + +## Windows + +**Please only use forward-slashes in glob expressions.** + +Though windows uses either `/` or `\` as its path separator, only `/` +characters are used by this glob implementation. You must use +forward-slashes **only** in glob expressions. Back-slashes will always +be interpreted as escape characters, not path separators. + +Results from absolute patterns such as `/foo/*` are mounted onto the +root setting using `path.join`. On windows, this will by default result +in `/foo/*` matching `C:\foo\bar.txt`. + +## Race Conditions + +Glob searching, by its very nature, is susceptible to race conditions, +since it relies on directory walking and such. + +As a result, it is possible that a file that exists when glob looks for +it may have been deleted or modified by the time it returns the result. + +As part of its internal implementation, this program caches all stat +and readdir calls that it makes, in order to cut down on system +overhead. However, this also makes it even more susceptible to races, +especially if the cache or statCache objects are reused between glob +calls. + +Users are thus advised not to use a glob result as a guarantee of +filesystem state in the face of rapid changes. For the vast majority +of operations, this is never a problem. + +## Glob Logo +Glob's logo was created by [Tanya Brassie](http://tanyabrassie.com/).

If you use sync methods which open file descriptors then you are +responsible for dealing with any errors. + +This is a known limitation, not a bug. + +## Global Patching + +If you want to patch the global fs module (or any other fs-like +module) you can do this: + +```javascript +// Make sure to read the caveat below. +var realFs = require('fs') +var gracefulFs = require('graceful-fs') +gracefulFs.gracefulify(realFs) +``` + +This should only ever be done at the top-level application layer, in +order to delay on EMFILE errors from any fs-using dependencies. You +should **not** do this in a library, because it can cause unexpected +delays in other parts of the program. + +## Changes + +This module is fairly stable at this point, and used by a lot of +things. That being said, because it implements a subtle behavior +change in a core part of the node API, even modest changes can be +extremely breaking, and the versioning is thus biased towards +bumping the major when in doubt. + +The main change between major versions has been switching between +providing a fully-patched `fs` module vs monkey-patching the node core +builtin, and the approach by which a non-monkey-patched `fs` was +created. + +The goal is to trade `EMFILE` errors for slower fs operations. So, if +you try to open a zillion files, rather than crashing, `open` +operations will be queued up and wait for something else to `close`. + +There are advantages to each approach. Monkey-patching the fs means +that no `EMFILE` errors can possibly occur anywhere in your +application, because everything is using the same core `fs` module, +which is patched. However, it can also obviously cause undesirable +side-effects, especially if the module is loaded multiple times. + +Implementing a separate-but-identical patched `fs` module is more +surgical (and doesn't run the risk of patching multiple times), but +also imposes the challenge of keeping in sync with the core module. + +The current approach loads the `fs` module, and then creates a +lookalike object that has all the same methods, except a few that are +patched. It is safe to use in all versions of Node from 0.8 through +7.0. + +### v4 + +* Do not monkey-patch the fs module. This module may now be used as a + drop-in dep, and users can opt into monkey-patching the fs builtin + if their app requires it. + +### v3 + +* Monkey-patch fs, because the eval approach no longer

FlagShort FlagDescription
--help-hShow this help.
--version-vPrint the global and local gulp versions.
--require [path]Will require a module before running the gulpfile. This is useful for transpilers but also has other applications.
--gulpfile [path]-fManually set path of gulpfile. Useful if you have multiple gulpfiles. This will set the CWD to the gulpfile directory as well.
--cwd [path]Manually set the CWD. The search for the gulpfile, as well as the relativity of all requires (including the `--require` flag) will be from here.
--verify [path (optional)]Will verify plugins referenced in project's package.json against the plugins blacklist.
--tasks-TPrint the task dependency tree for the loaded gulpfile.
--tasks-simplePrint a plaintext list of tasks for the loaded gulpfile.
--tasks-json [path]Print the task dependency tree, in JSON format, for the loaded gulpfile. The [path] argument is optional, and if given writes the JSON to the path.
--tasks-depth [number]Specify the depth of the task dependency tree to print. This flag can be used with --tasks or --tasks-json. (This flag was named --depth before but is deprecated.)
--compact-tasksReduce the output of task dependency tree by printing only top tasks and their child tasks. This flag can be used with --tasks or --tasks-json.
--sort-tasksWill sort top tasks of task dependency tree. This flag can be used with --tasks.
--colorWill force gulp and gulp plugins to display colors, even when no color support is detected.
--no-colorWill force gulp and gulp plugins to not display colors, even when color support is detected.
--silent-SSuppress all gulp logging.
--continueContinue execution of tasks upon failure.
--seriesRun tasks given on the CLI in series (the default is parallel).
--log-level-LSet the loglevel. -L for least verbose and -LLLL for most verbose. -LLL is default.

[migration guide](#migrating-to-version-5).** + +## Support + +Only [Active LTS and Current releases](https://github.com/nodejs/Release#release-schedule) are supported. + +## Installation + +To use `gulp-sass`, you must install both `gulp-sass` itself *and* a Sass compiler. `gulp-sass` supports both [Dart Sass][] and [Node Sass][], although Node Sass is [deprecated](https://sass-lang.com/blog/libsass-is-deprecated). We recommend that you use Dart Sass for new projects, and migrate Node Sass projects to Dart Sass when possible. + +Whichever compiler you choose, it's best to install these as dev dependencies: + +```sh +npm install sass gulp-sass --save-dev +``` + +### Importing it into your project + +`gulp-sass` must be imported into your gulpfile, where you provide it the compiler of your choice. To use `gulp-sass` in a CommonJS module (which is most Node.js environments), do something like this: + +```js +const sass = require('gulp-sass')(require('sass')); +``` + +To use `gulp-sass` in an ECMAScript module (which is supported in newer Node.js 14 and later), do something like this: + +```js +import dartSass from 'sass'; +import gulpSass from 'gulp-sass'; +const sass = gulpSass(dartSass); +``` + +## Usage + +**Note:** These examples are written for CommonJS modules and assume you're using Gulp 4. For examples that work with Gulp 3, [check the docs for an earlier version of `gulp-sass`](https://github.com/dlmanning/gulp-sass/tree/v4.1.1). + +`gulp-sass` must be used in a Gulp task. Your task can call `sass()` (to asynchronously render your CSS), or `sass.sync()` (to synchronously render your CSS). Then, export your task with the `export` keyword. We'll show some examples of how to do that. + +**⚠️ Note:** When using Dart Sass, **synchronous rendering is twice as fast as asynchronous rendering**. The Sass team is exploring ways to improve asynchronous rendering with Dart Sass, but for now, you will get the best performance from `sass.sync()`. If performance is critical, you can use `node-sass` instead, but bear in mind that `node-sass` may not support modern Sass features you rely on. + +### Render your CSS + +To render your CSS with a build task, then watch your files for changes, you might write something like this: + +```js +'use strict'; + +const gulp = require('gulp'); +const sass = require('gulp-sass')(require('sass')); + +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sass().on('error', sass.logError)) + .pipe(gulp.dest('./css')); +}; + +exports.buildStyles = buildStyles; +exports.watch = function () { + gulp.watch('./sass/**/*.scss', ['sass']); +}; +``` + +With synchronous rendering, that Gulp task looks like this: + +```js +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sass.sync().on('error', sass.logError)) + .pipe(gulp.dest('./css')); +}; +``` + +### Render with options + +To change the final output of your CSS, you can pass an options object to your renderer. `gulp-sass` supports [Node Sass's render options](https://github.com/sass/node-sass#options), with two unsupported exceptions: + +- The `data` option, which is used by `gulp-sass` internally. +- The `file` option, which has undefined behavior that may change without notice. + +For example, to compress your CSS, you can call `sass({outputStyle: 'compressed'}`. In the context of a Gulp task, that looks like this: + +```js +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError)) + .pipe(gulp.dest('./css')); +}; + +exports.buildStyles = buildStyles; +``` + +Or this for synchronous rendering: + +```js +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sass.sync({outputStyle: 'compressed'}).on('error', sass.logError)) + .pipe(gulp.dest('./css')); +}; + +exports.buildStyles = buildStyles; +``` + +### Include a source map + +`gulp-sass` can be used in tandem with [`gulp-sourcemaps`](https://github.com/gulp-sourcemaps/gulp-sourcemaps) to generate source maps for the Sass-to-CSS compilation. You will need to initialize `gulp-sourcemaps` _before_ running `gulp-sass`, and write the source maps after. + +```js +const sourcemaps = require('gulp-sourcemaps'); + +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sourcemaps.init()) + .pipe(sass().on('error', sass.logError)) + .pipe(sourcemaps.write()) + .pipe(gulp.dest('./css')); +} + +exports.buildStyles = buildStyles; +``` + +By default, `gulp-sourcemaps` writes the source maps inline, in the compiled CSS files. To write them to a separate file, specify a path relative to the `gulp.dest()` destination in the `sourcemaps.write()` function. + +```js +const sourcemaps = require('gulp-sourcemaps'); + +function buildStyles() { + return gulp.src('./sass/**/*.scss') + .pipe(sourcemaps.init()) + .pipe(sass().on('error', sass.logError)) + .pipe(sourcemaps.write('./maps')) + .pipe(gulp.dest('./css')); +}; + +exports.buildStyles = buildStyles; +``` + +

Migrating to version 5

+ +`gulp-sass` version 5 requires Node.js 12 or later, and introduces some breaking changes. Additionally, changes in Node.js itself mean that Node fibers can no longer be used to speed up Dart Sass in Node.js 16. + +### Setting a Sass compiler + +As of version 5, `gulp-sass` _does not include a default Sass compiler_, so you must install one (either `node-sass` or `sass`) along with `gulp-sass`. + +```sh +npm install sass gulp-sass --save-dev +``` + +Then, you must explicitly set that compiler in your gulpfille. Instead of setting a `compiler` prop on the `gulp-sass` instance, you pass the compiler into a function call when instantiating `gulp-sass`. + +These changes look something like this: + +```diff +- const sass = require('gulp-sass')); +- const compiler = require('sass'); +- sass.compiler = compiler; ++ const sass = require('gulp-sass')(require('sass')); +``` + +If you're migrating an ECMAScript module, that'll look something like this: + +```diff +import dartSass from 'sass'; +- import sass from 'gulp-sass'; +- sass.compiler = dartSass; + +import dartSass from 'sass'; ++ import gulpSass from 'gulp-sass'; ++ const sass = gulpSass(dartSass); +``` + +### What about fibers? + +We used to recommend Node fibers as a way to speed up asynchronous rendering with Dart Sass. Unfortunately, [Node fibers are discontinued](https://sass-lang.com/blog/node-fibers-discontinued) and will not work in Node.js 16. The Sass team is exploring its options for future performance improvements, but for now, you will get the best performance from `sass.sync()`. + +## Issues + +`gulp-sass` is a light-weight wrapper around either [Dart Sass][] or [Node Sass][] (which in turn is a Node.js binding for [LibSass][]. Because of this, the issue you're having likely isn't a `gulp-sass` issue, but an issue with one those projects or with [Sass][] as a whole. + +If you have a feature request/question about how Sass works/concerns on how your Sass gets compiled/errors in your compiling, it's likely a Dart Sass or LibSass issue and you should file your issue with one of those projects. + +If you're having problems with the options you're passing in, it's likely a Dart Sass or Node Sass issue and you should file your issue with one of those projects. + +We may, in the course of resolving issues, direct you to one of these other projects.

At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary.

Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3.

Github specifically, is detected in the case +of a third, unprefixed, form: `npm/hosted-git-info`. + +If it does match, the returned object has properties of: + +* info.type -- The short name of the service +* info.domain -- The domain for git protocol use +* info.user -- The name of the user/org on the git host +* info.project -- The name of the project on the git host + +## Version Contract + +The major version will be bumped any time… + +* The constructor stops accepting URLs that it previously accepted. +* A method is removed. +* A method can no longer accept the number and type of arguments it previously accepted. +* A method can return a different type than it currently returns. + +Implications: + +* I do not consider the specific format of the urls returned from, say + `.https()` to be a part of the contract. The contract is that it will + return a string that can be used to fetch the repo via HTTPS.

It can have the following properties: + * *noCommittish* — If true then committishes won't be included in generated URLs. + * *noGitPlus* — If true then `git+` won't be prefixed on URLs. + +## Methods + +All of the methods take the same options as the `fromUrl` factory. Options +provided to a method override those provided to the constructor. + +* info.file(path, opts) + +Given the path of a file relative to the repository, returns a URL for +directly fetching it from the githost. If no committish was set then +`master` will be used as the default. + +For example `hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git#v1.0.0").file("package.json")` +would return `https://raw.githubusercontent.com/npm/hosted-git-info/v1.0.0/package.json` + +* info.shortcut(opts) + +eg, `github:npm/hosted-git-info` + +* info.browse(path, fragment, opts) + +eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0`, +`https://github.com/npm/hosted-git-info/tree/v1.2.0/package.json`, +`https://github.com/npm/hosted-git-info/tree/v1.2.0/REAMDE.md#supported-hosts` + +* info.bugs(opts) + +eg, `https://github.com/npm/hosted-git-info/issues` + +* info.docs(opts) + +eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0#readme` + +* info.https(opts) + +eg, `git+https://github.com/npm/hosted-git-info.git` + +* info.sshurl(opts) + +eg, `git+ssh://git@github.com/npm/hosted-git-info.git` + +* info.ssh(opts) + +eg, `git@github.com:npm/hosted-git-info.git` + +* info.path(opts) + +eg, `npm/hosted-git-info` + +* info.tarball(opts) + +eg, `https://github.com/npm/hosted-git-info/archive/v1.2.0.tar.gz` + +* info.getDefaultRepresentation() + +Returns the default output type.

The `immutable` npm module works +without any additional consideration. All examples throughout the documentation +will assume use of this kind of tool. + +Alternatively, Immutable.js may be directly included as a script tag. Download +or link to a CDN such as [CDNJS](https://cdnjs.com/libraries/immutable) +or [jsDelivr](https://www.jsdelivr.com/package/npm/immutable). + +Use a script tag to directly add `Immutable` to the global scope: + +```html + + +``` + +Or use an AMD-style loader (such as [RequireJS](https://requirejs.org/)): + +```js +require(['./immutable.min.js'], function (Immutable) { + var map1 = Immutable.Map({ a: 1, b: 2, c: 3 }); + var map2 = map1.set('b', 50); + map1.get('b'); // 2 + map2.get('b'); // 50 +}); +``` + +### Flow & TypeScript + +Use these Immutable collections and sequences as you would use native +collections in your [Flowtype](https://flowtype.org/) or [TypeScript](https://typescriptlang.org) programs while still taking +advantage of type generics, error detection, and auto-complete in your IDE. + +Installing `immutable` via npm brings with it type definitions for Flow (v0.55.0 or higher) +and TypeScript (v2.1.0 or higher), so you shouldn't need to do anything at all! + +#### Using TypeScript with Immutable.js v4 + +Immutable.js type definitions embrace ES2015. While Immutable.js itself supports +legacy browsers and environments, its type definitions require TypeScript's 2015 +lib. Include either `"target": "es2015"` or `"lib": "es2015"` in your +`tsconfig.json`, or provide `--target es2015` or `--lib es2015` to the +`tsc` command. + + + +```js +const { Map } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3 }); +const map2 = map1.set('b', 50); +map1.get('b') + ' vs. ' + map2.get('b'); // 2 vs. 50 +``` + +#### Using TypeScript with Immutable.js v3 and earlier: + +Previous versions of Immutable.js include a reference file which you can include +via relative path to the type definitions at the top of your file. + +```js +/// +import Immutable from 'immutable'; +var map1: Immutable.Map; +map1 = Immutable.Map({ a: 1, b: 2, c: 3 }); +var map2 = map1.set('b', 50); +map1.get('b'); // 2 +map2.get('b'); // 50 +``` + +## The case for Immutability + +Much of what makes application development difficult is tracking mutation and +maintaining state. Developing with immutable data encourages you to think +differently about how data flows through your application. + +Subscribing to data events throughout your application creates a huge overhead of +book-keeping which can hurt performance, sometimes dramatically, and creates +opportunities for areas of your application to get out of sync with each other +due to easy to make programmer error. Since immutable data never changes, +subscribing to changes throughout the model is a dead-end and new data can only +ever be passed from above. + +This model of data flow aligns well with the architecture of [React][] +and especially well with an application designed using the ideas of [Flux][]. + +When data is passed from above rather than being subscribed to, and you're only +interested in doing work when something has changed, you can use equality. + +Immutable collections should be treated as _values_ rather than _objects_. While +objects represent some thing which could change over time, a value represents +the state of that thing at a particular instance of time. This principle is most +important to understanding the appropriate use of immutable data. In order to +treat Immutable.js collections as values, it's important to use the +`Immutable.is()` function or `.equals()` method to determine _value equality_ +instead of the `===` operator which determines object _reference identity_. + + + +```js +const { Map } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3 }); +const map2 = Map({ a: 1, b: 2, c: 3 }); +map1.equals(map2); // true +map1 === map2; // false +``` + +Note: As a performance optimization Immutable.js attempts to return the existing +collection when an operation would result in an identical collection, allowing +for using `===` reference equality to determine if something definitely has not +changed. This can be extremely useful when used within a memoization function +which would prefer to re-run the function if a deeper equality check could +potentially be more costly. The `===` equality check is also used internally by +`Immutable.is` and `.equals()` as a performance optimization. + + + +```js +const { Map } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3 }); +const map2 = map1.set('b', 2); // Set to same value +map1 === map2; // true +``` + +If an object is immutable, it can be "copied" simply by making another reference +to it instead of copying the entire object. Because a reference is much smaller +than the object itself, this results in memory savings and a potential boost in +execution speed for programs which rely on copies (such as an undo-stack). + + + +```js +const { Map } = require('immutable'); +const map = Map({ a: 1, b: 2, c: 3 }); +const mapCopy = map; // Look, "copies" are free! +``` + +[React]: https://reactjs.org/ +[Flux]: https://facebook.github.io/flux/docs/in-depth-overview/ + + +## JavaScript-first API + +While Immutable.js is inspired by Clojure, Scala, Haskell and other functional +programming environments, it's designed to bring these powerful concepts to +JavaScript, and therefore has an Object-Oriented API that closely mirrors that +of [ES2015][] [Array][], [Map][], and [Set][]. + +[es2015]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/ECMAScript_6_support_in_Mozilla +[array]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array +[map]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map +[set]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set + +The difference for the immutable collections is that methods which would mutate +the collection, like `push`, `set`, `unshift` or `splice`, instead return a new +immutable collection. Methods which return new arrays, like `slice` or `concat`, +instead return new immutable collections. + + + +```js +const { List } = require('immutable'); +const list1 = List([1, 2]); +const list2 = list1.push(3, 4, 5); +const list3 = list2.unshift(0); +const list4 = list1.concat(list2, list3); +assert.equal(list1.size, 2); +assert.equal(list2.size, 5); +assert.equal(list3.size, 6); +assert.equal(list4.size, 13); +assert.equal(list4.get(0), 1); +``` + +Almost all of the methods on [Array][] will be found in similar form on +`Immutable.List`, those of [Map][] found on `Immutable.Map`, and those of [Set][] +found on `Immutable.Set`, including collection operations like `forEach()` +and `map()`. + + + +```js +const { Map } = require('immutable'); +const alpha = Map({ a: 1, b: 2, c: 3, d: 4 }); +alpha.map((v, k) => k.toUpperCase()).join(); +// 'A,B,C,D' +``` + +### Convert from raw JavaScript objects and arrays. + +Designed to inter-operate with your existing JavaScript, Immutable.js +accepts plain JavaScript Arrays and Objects anywhere a method expects a +`Collection`. + + + +```js +const { Map, List } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3, d: 4 }); +const map2 = Map({ c: 10, a: 20, t: 30 }); +const obj = { d: 100, o: 200, g: 300 }; +const map3 = map1.merge(map2, obj); +// Map { a: 20, b: 2, c: 10, d: 100, t: 30, o: 200, g: 300 } +const list1 = List([1, 2, 3]); +const list2 = List([4, 5, 6]); +const array = [7, 8, 9]; +const list3 = list1.concat(list2, array); +// List [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ] +``` + +This is possible because Immutable.js can treat any JavaScript Array or Object +as a Collection. You can take advantage of this in order to get sophisticated +collection methods on JavaScript Objects, which otherwise have a very sparse +native API. Because Seq evaluates lazily and does not cache intermediate +results, these operations can be extremely efficient. + + + +```js +const { Seq } = require('immutable'); +const myObject = { a: 1, b: 2, c: 3 }; +Seq(myObject) + .map(x => x * x) + .toObject(); +// { a: 1, b: 4, c: 9 } +``` + +Keep in mind, when using JS objects to construct Immutable Maps, that +JavaScript Object properties are always strings, even if written in a quote-less +shorthand, while Immutable Maps accept keys of any type. + + + +```js +const { fromJS } = require('immutable'); + +const obj = { 1: 'one' }; +console.log(Object.keys(obj)); // [ "1" ] +console.log(obj['1'], obj[1]); // "one", "one" + +const map = fromJS(obj); +console.log(map.get('1'), map.get(1)); // "one", undefined +``` + +Property access for JavaScript Objects first converts the key to a string, but +since Immutable Map keys can be of any type the argument to `get()` is +not altered. + +### Converts back to raw JavaScript objects. + +All Immutable.js Collections can be converted to plain JavaScript Arrays and +Objects shallowly with `toArray()` and `toObject()` or deeply with `toJS()`. +All Immutable Collections also implement `toJSON()` allowing them to be passed +to `JSON.stringify` directly. They also respect the custom `toJSON()` methods of +nested objects. + + + +```js +const { Map, List } = require('immutable'); +const deep = Map({ a: 1, b: 2, c: List([3, 4, 5]) }); +console.log(deep.toObject()); // { a: 1, b: 2, c: List [ 3, 4, 5 ] } +console.log(deep.toArray()); // [ 1, 2, List [ 3, 4, 5 ] ] +console.log(deep.toJS()); // { a: 1, b: 2, c: [ 3, 4, 5 ] } +JSON.stringify(deep); // '{"a":1,"b":2,"c":[3,4,5]}' +``` + +### Embraces ES2015 + +Immutable.js supports all JavaScript environments, including legacy +browsers (even IE11). However it also takes advantage of features added to +JavaScript in [ES2015][], the latest standard version of JavaScript, including +[Iterators][], [Arrow Functions][], [Classes][], and [Modules][]. It's inspired +by the native [Map][] and [Set][] collections added to ES2015. + +All examples in the Documentation are presented in ES2015. To run in all +browsers, they need to be translated to ES5. + +```js +// ES2015 +const mapped = foo.map(x => x * x); +// ES5 +var mapped = foo.map(function (x) { + return x * x; +}); +``` + +All Immutable.js collections are [Iterable][iterators], which allows them to be +used anywhere an Iterable is expected, such as when spreading into an Array. + + + +```js +const { List } = require('immutable'); +const aList = List([1, 2, 3]); +const anArray = [0, ...aList, 4, 5]; // [ 0, 1, 2, 3, 4, 5 ] +``` + +Note: A Collection is always iterated in the same order, however that order may +not always be well defined, as is the case for the `Map` and `Set`. + +[Iterators]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/The_Iterator_protocol +[Arrow Functions]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions +[Classes]: https://wiki.ecmascript.org/doku.php?id=strawman:maximally_minimal_classes +[Modules]: https://www.2ality.com/2014/09/es6-modules-final.html + + +## Nested Structures + +The collections in Immutable.js are intended to be nested, allowing for deep +trees of data, similar to JSON. + + + +```js +const { fromJS } = require('immutable'); +const nested = fromJS({ a: { b: { c: [3, 4, 5] } } }); +// Map { a: Map { b: Map { c: List [ 3, 4, 5 ] } } } +``` + +A few power-tools allow for reading and operating on nested data. The +most useful are `mergeDeep`, `getIn`, `setIn`, and `updateIn`, found on `List`, +`Map` and `OrderedMap`. + + + +```js +const { fromJS } = require('immutable'); +const nested = fromJS({ a: { b: { c: [3, 4, 5] } } }); + +const nested2 = nested.mergeDeep({ a: { b: { d: 6 } } }); +// Map { a: Map { b: Map { c: List [ 3, 4, 5 ], d: 6 } } } + +console.log(nested2.getIn(['a', 'b', 'd'])); // 6 + +const nested3 = nested2.updateIn(['a', 'b', 'd'], value => value + 1); +console.log(nested3); +// Map { a: Map { b: Map { c: List [ 3, 4, 5 ], d: 7 } } } + +const nested4 = nested3.updateIn(['a', 'b', 'c'], list => list.push(6)); +// Map { a: Map { b: Map { c: List [ 3, 4, 5, 6 ], d: 7 } } } +``` + +## Equality treats Collections as Values + +Immutable.js collections are treated as pure data _values_. Two immutable +collections are considered _value equal_ (via `.equals()` or `is()`) if they +represent the same collection of values. This differs from JavaScript's typical +_reference equal_ (via `===` or `==`) for Objects and Arrays which only +determines if two variables represent references to the same object instance. + +Consider the example below where two identical `Map` instances are not +_reference equal_ but are _value equal_. + + + +```js +// First consider: +const obj1 = { a: 1, b: 2, c: 3 }; +const obj2 = { a: 1, b: 2, c: 3 }; +obj1 !== obj2; // two different instances are always not equal with === + +const { Map, is } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3 }); +const map2 = Map({ a: 1, b: 2, c: 3 }); +map1 !== map2; // two different instances are not reference-equal +map1.equals(map2); // but are value-equal if they have the same values +is(map1, map2); // alternatively can use the is() function +``` + +Value equality allows Immutable.js collections to be used as keys in Maps or +values in Sets, and retrieved with different but equivalent collections: + + + +```js +const { Map, Set } = require('immutable'); +const map1 = Map({ a: 1, b: 2, c: 3 }); +const map2 = Map({ a: 1, b: 2, c: 3 }); +const set = Set().add(map1); +set.has(map2); // true because these are value-equal +``` + +Note: `is()` uses the same measure of equality as [Object.is][] for scalar +strings and numbers, but uses value equality for Immutable collections, +determining if both are immutable and all keys and values are equal +using the same measure of equality. + +[object.is]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is + +#### Performance tradeoffs + +While value equality is useful in many circumstances, it has different +performance characteristics than reference equality. Understanding these +tradeoffs may help you decide which to use in each case, especially when used +to memoize some operation. + +When comparing two collections, value equality may require considering every +item in each collection, on an `O(N)` time complexity. For large collections of +values, this could become a costly operation. Though if the two are not equal +and hardly similar, the inequality is determined very quickly. In contrast, when +comparing two collections with reference equality, only the initial references +to memory need to be compared which is not based on the size of the collections, +which has an `O(1)` time complexity. Checking reference equality is always very +fast, however just because two collections are not reference-equal does not rule +out the possibility that they may be value-equal. + +#### Return self on no-op optimization + +When possible, Immutable.js avoids creating new objects for updates where no +change in _value_ occurred, to allow for efficient _reference equality_ checking +to quickly determine if no change occurred. + + + +```js +const { Map } = require('immutable'); +const originalMap = Map({ a: 1, b: 2, c: 3 }); +const updatedMap = originalMap.set('b', 2); +updatedMap === originalMap; // No-op .set() returned the original reference. +``` + +However updates which do result in a change will return a new reference. Each +of these operations occur independently, so two similar updates will not return +the same reference: + + + +```js +const { Map } = require('immutable'); +const originalMap = Map({ a: 1, b: 2, c: 3 }); +const updatedMap = originalMap.set('b', 1000); +// New instance, leaving the original immutable. +updatedMap !== originalMap; +const anotherUpdatedMap = originalMap.set('b', 1000); +// Despite both the results of the same operation, each created a new reference. +anotherUpdatedMap !== updatedMap; +// However the two are value equal. +anotherUpdatedMap.equals(updatedMap); +``` + +## Batching Mutations + +> If a tree falls in the woods, does it make a sound? +> +> If a pure function mutates some local data in order to produce an immutable +> return value, is that ok? +> +> — Rich Hickey, Clojure + +Applying a mutation to create a new immutable object results in some overhead, +which can add up to a minor performance penalty. If you need to apply a series +of mutations locally before returning, Immutable.js gives you the ability to +create a temporary mutable (transient) copy of a collection and apply a batch of +mutations in a performant manner by using `withMutations`. In fact, this is +exactly how Immutable.js applies complex mutations itself. + +As an example, building `list2` results in the creation of 1, not 3, new +immutable Lists. + + + +```js +const { List } = require('immutable'); +const list1 = List([1, 2, 3]); +const list2 = list1.withMutations(function (list) { + list.push(4).push(5).push(6); +}); +assert.equal(list1.size, 3); +assert.equal(list2.size, 6); +``` + +Note: Immutable.js also provides `asMutable` and `asImmutable`, but only +encourages their use when `withMutations` will not suffice. Use caution to not +return a mutable copy, which could result in undesired behavior. + +_Important!_: Only a select few methods can be used in `withMutations` including +`set`, `push` and `pop`. These methods can be applied directly against a +persistent data-structure where other methods like `map`, `filter`, `sort`, +and `splice` will always return new immutable data-structures and never mutate +a mutable collection. + +## Lazy Seq + +`Seq` describes a lazy operation, allowing them to efficiently chain +use of all the higher-order collection methods (such as `map` and `filter`) +by not creating intermediate collections. + +**Seq is immutable** — Once a Seq is created, it cannot be +changed, appended to, rearranged or otherwise modified. Instead, any mutative +method called on a `Seq` will return a new `Seq`. + +**Seq is lazy** — `Seq` does as little work as necessary to respond to any +method call. Values are often created during iteration, including implicit +iteration when reducing or converting to a concrete data structure such as +a `List` or JavaScript `Array`. + +For example, the following performs no work, because the resulting +`Seq`'s values are never iterated: + +```js +const { Seq } = require('immutable'); +const oddSquares = Seq([1, 2, 3, 4, 5, 6, 7, 8]) + .filter(x => x % 2 !== 0) + .map(x => x * x); +``` + +Once the `Seq` is used, it performs only the work necessary. In this +example, no intermediate arrays are ever created, filter is called three +times, and map is only called once: + +```js +oddSquares.get(1); // 9 +``` + +Any collection can be converted to a lazy Seq with `Seq()`. + + + +```js +const { Map, Seq } = require('immutable'); +const map = Map({ a: 1, b: 2, c: 3 }); +const lazySeq = Seq(map); +``` + +`Seq` allows for the efficient chaining of operations, allowing for the +expression of logic that can otherwise be very tedious: + +```js +lazySeq + .flip() + .map(key => key.toUpperCase()) + .flip(); +// Seq { A: 1, B: 2, C: 3 } +``` + +As well as expressing logic that would otherwise seem memory or time +limited, for example `Range` is a special kind of Lazy sequence. + + + +```js +const { Range } = require('immutable'); +Range(1, Infinity) + .skip(1000) + .map(n => -n) + .filter(n => n % 2 === 0) + .take(2) + .reduce((r, n) => r * n, 1); +// 1006008 +``` + +## Additional Tools and Resources + +- [Atom-store](https://github.com/jameshopkins/atom-store/) + - A Clojure-inspired atom implementation in Javascript with configurability + for external persistance. + +- [Chai Immutable](https://github.com/astorije/chai-immutable) + - If you are using the [Chai Assertion Library](https://chaijs.com/), this + provides a set of assertions to use against Immutable.js collections. + +- [Fantasy-land](https://github.com/fantasyland/fantasy-land) + - Specification for interoperability of common algebraic structures in JavaScript. + +- [Immutagen](https://github.com/pelotom/immutagen) + - A library for simulating immutable generators in JavaScript. + +- [Immutable-cursor](https://github.com/redbadger/immutable-cursor) + - Immutable cursors incorporating the Immutable.js interface over + Clojure-inspired atom. + +- [Immutable-ext](https://github.com/DrBoolean/immutable-ext) + - Fantasyland extensions for immutablejs + +- [Immutable-js-tools](https://github.com/madeinfree/immutable-js-tools) + - Util tools for immutable.js + +- [Immutable-Redux](https://github.com/gajus/redux-immutable) + - redux-immutable is used to create an equivalent function of Redux + combineReducers that works with Immutable.js state. + +- [Immutable-Treeutils](https://github.com/lukasbuenger/immutable-treeutils) + - Functional tree traversal helpers for ImmutableJS data structures. + +- [Irecord](https://github.com/ericelliott/irecord) + - An immutable store that exposes an RxJS observable.

It is easy and efficient to convert to + * and from plain Javascript types. + * + * ## How to read these docs + * + * In order to better explain what kinds of values the Immutable.js API expects + * and produces, this documentation is presented in a statically typed dialect of + * JavaScript (like [Flow][] or [TypeScript][]). You *don't need* to use these + * type checking tools in order to use Immutable.js, however becoming familiar + * with their syntax will help you get a deeper understanding of this API. + * + * **A few examples and how to read them.** + * + * All methods describe the kinds of data they accept and the kinds of data + * they return. For example a function which accepts two numbers and returns + * a number would look like this: + * + * ```js + * sum(first: number, second: number): number + * ``` + * + * Sometimes, methods can accept different kinds of data or return different + * kinds of data, and this is described with a *type variable*, which is + * typically in all-caps. For example, a function which always returns the same + * kind of data it was provided would look like this: + * + * ```js + * identity(value: T): T + * ``` + * + * Type variables are defined with classes and referred to in methods. For + * example, a class that holds onto a value for you might look like this: + * + * ```js + * class Box { + * constructor(value: T) + * getValue(): T + * } + * ``` + * + * In order to manipulate Immutable data, methods that we're used to affecting + * a Collection instead return a new Collection of the same type. The type + * `this` refers to the same kind of class. For example, a List which returns + * new Lists when you `push` a value onto it might look like: + * + * ```js + * class List { + * push(value: T): this + * } + * ``` + * + * Many methods in Immutable.js accept values which implement the JavaScript + * [Iterable][] protocol, and might appear like `Iterable` for something + * which represents sequence of strings. Typically in JavaScript we use plain + * Arrays (`[]`) when an Iterable is expected, but also all of the Immutable.js + * collections are iterable themselves! + * + * For example, to get a value deep within a structure of data, we might use + * `getIn` which expects an `Iterable` path: + * + * ``` + * getIn(path: Iterable): unknown + * ``` + * + * To use this method, we could pass an array: `data.getIn([ "key", 2 ])`. + * + * + * Note: All examples are presented in the modern [ES2015][] version of + * JavaScript. Use tools like Babel to support older browsers. + * + * For example: + * + * ```js + * // ES2015 + * const mappedFoo = foo.map(x => x * x); + * // ES5 + * var mappedFoo = foo.map(function (x) { return x * x; }); + * ``` + * + * [ES2015]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/ECMAScript_6_support_in_Mozilla + * [TypeScript]: https://www.typescriptlang.org/ + * [Flow]: https://flowtype.org/ + * [Iterable]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols + */ + +declare namespace Immutable { + /** + * Lists are ordered indexed dense collections, much like a JavaScript + * Array. + * + * Lists are immutable and fully persistent with O(log32 N) gets and sets, + * and O(1) push and pop. + * + * Lists implement Deque, with efficient addition and removal from both the + * end (`push`, `pop`) and beginning (`unshift`, `shift`). + * + * Unlike a JavaScript Array, there is no distinction between an + * "unset" index and an index set to `undefined`. `List#forEach` visits all + * indices from 0 to size, regardless of whether they were explicitly defined. + */ + namespace List { + /** + * True if the provided value is a List + * + * + * ```js + * const { List } = require('immutable'); + * List.isList([]); // false + * List.isList(List()); // true + * ``` + */ + function isList(maybeList: unknown): maybeList is List; + + /** + * Creates a new List containing `values`. + * + * + * ```js + * const { List } = require('immutable'); + * List.of(1, 2, 3, 4) + * // List [ 1, 2, 3, 4 ] + * ``` + * + * Note: Values are not altered or converted in any way. + * + * + * ```js + * const { List } = require('immutable'); + * List.of({x:1}, 2, [3], 4) + * // List [ { x: 1 }, 2, [ 3 ], 4 ] + * ``` + */ + function of(...values: Array): List; + } + + /** + * Create a new immutable List containing the values of the provided + * collection-like. + * + * Note: `List` is a factory function and not a class, and does not use the + * `new` keyword during construction. + * + * + * ```js + * const { List, Set } = require('immutable') + * + * const emptyList = List() + * // List [] + * + * const plainArray = [ 1, 2, 3, 4 ] + * const listFromPlainArray = List(plainArray) + * // List [ 1, 2, 3, 4 ] + * + * const plainSet = Set([ 1, 2, 3, 4 ]) + * const listFromPlainSet = List(plainSet) + * // List [ 1, 2, 3, 4 ] + * + * const arrayIterator = plainArray[Symbol.iterator]() + * const listFromCollectionArray = List(arrayIterator) + * // List [ 1, 2, 3, 4 ] + * + * listFromPlainArray.equals(listFromCollectionArray) // true + * listFromPlainSet.equals(listFromCollectionArray) // true + * listFromPlainSet.equals(listFromPlainArray) // true + * ``` + */ + function List(collection?: Iterable | ArrayLike): List; + + interface List extends Collection.Indexed { + /** + * The number of items in this List. + */ + readonly size: number; + + // Persistent changes + + /** + * Returns a new List which includes `value` at `index`.

This is generally discouraged in favor of a more functional API, + * since Subclasses have some minor overhead. However the ability to create + * a rich API on Record types can be quite valuable. + * + * When using Flow to type Subclasses, do not use `RecordFactory`, + * instead apply the props type when subclassing: + * + * ```js + * type PersonProps = {name: string, age: number}; + * const defaultValues: PersonProps = {name: 'Aristotle', age: 2400}; + * const PersonRecord = Record(defaultValues); + * class Person extends PersonRecord { + * getName(): string { + * return this.get('name') + * } + * + * setName(name: string): this { + * return this.set('name', name); + * } + * } + * ``` + * + * **Choosing Records vs plain JavaScript objects** + * + * Records offer a persistently immutable alternative to plain JavaScript + * objects, however they're not required to be used within Immutable.js + * collections. In fact, the deep-access and deep-updating functions + * like `getIn()` and `setIn()` work with plain JavaScript Objects as well. + * + * Deciding to use Records or Objects in your application should be informed + * by the tradeoffs and relative benefits of each: + * + * - *Runtime immutability*: plain JS objects may be carefully treated as + * immutable, however Record instances will *throw* if attempted to be + * mutated directly. Records provide this additional guarantee, however at + * some marginal runtime cost. While JS objects are mutable by nature, the + * use of type-checking tools like [Flow](https://medium.com/@gcanti/immutability-with-flow-faa050a1aef4) + * can help gain confidence in code written to favor immutability. + * + * - *Value equality*: Records use value equality when compared with `is()` + * or `record.equals()`. That is, two Records with the same keys and values + * are equal. Plain objects use *reference equality*. Two objects with the + * same keys and values are not equal since they are different objects. + * This is important to consider when using objects as keys in a `Map` or + * values in a `Set`, which use equality when retrieving values. + * + * - *API methods*: Records have a full featured API, with methods like + * `.getIn()`, and `.equals()`. These can make working with these values + * easier, but comes at the cost of not allowing keys with those names. + * + * - *Default values*: Records provide default values for every key, which + * can be useful when constructing Records with often unchanging values. + * However default values can make using Flow and TypeScript more laborious. + * + * - *Serialization*: Records use a custom internal representation to + * efficiently store and update their values. Converting to and from this + * form isn't free.

Equality is symmetrical, so the same result should be + * returned if this and the argument are flipped. + * + * assert( a.equals(b) === b.equals(a) ); + * + * `hashCode` returns a 32bit integer number representing the object which will + * be used to determine how to store the value object in a Map or Set. You must + * provide both or neither methods, one must not exist without the other. + * + * Also, an important relationship between these methods must be upheld: if two + * values are equal, they *must* return the same hashCode. If the values are not + * equal, they might have the same hashCode; this is called a hash collision, + * and while undesirable for performance reasons, it is acceptable. + * + * if (a.equals(b)) { + * assert( a.hashCode() === b.hashCode() ); + * } + * + * All Immutable collections are Value Objects: they implement `equals()` + * and `hashCode()`. + */ +function is(valueA, valueB) { + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + if ( + typeof valueA.valueOf === 'function' && + typeof valueB.valueOf === 'function' + ) { + valueA = valueA.valueOf(); + valueB = valueB.valueOf(); + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + } + return !!( + isValueObject(valueA) && + isValueObject(valueB) && + valueA.equals(valueB) + ); +} + +var imul = + typeof Math.imul === 'function' && Math.imul(0xffffffff, 2) === -2 + ?

For example, `Date` represents a value by returning a unix + * timestamp for `valueOf`: + * + * var date1 = new Date(1234567890000); // Fri Feb 13 2009 ... + * var date2 = new Date(1234567890000); + * date1.valueOf(); // 1234567890000 + * assert( date1 !== date2 ); + * assert( Immutable.is( date1, date2 ) ); + * + * Note: overriding `valueOf` may have other implications if you use this object + * where JavaScript expects a primitive, such as implicit string coercion. + * + * For more complex types, especially collections, implementing `valueOf` may + * not be performant. An alternative is to implement `equals` and `hashCode`. + * + * `equals` takes another object, presumably of similar type, and returns true + * if it is equal. Equality is symmetrical, so the same result should be + * returned if this and the argument are flipped. + * + * assert( a.equals(b) === b.equals(a) ); + * + * `hashCode` returns a 32bit integer number representing the object which will + * be used to determine how to store the value object in a Map or Set. You must + * provide both or neither methods, one must not exist without the other. + * + * Also, an important relationship between these methods must be upheld: if two + * values are equal, they *must* return the same hashCode. If the values are not + * equal, they might have the same hashCode; this is called a hash collision, + * and while undesirable for performance reasons, it is acceptable. + * + * if (a.equals(b)) { + * assert( a.hashCode() === b.hashCode() ); + * } + * + * All Immutable collections are Value Objects: they implement `equals()` + * and `hashCode()`. + */ + function is(valueA, valueB) { + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + if ( + typeof valueA.valueOf === 'function' && + typeof valueB.valueOf === 'function' + ) { + valueA = valueA.valueOf(); + valueB = valueB.valueOf(); + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + } + return !!( + isValueObject(valueA) && + isValueObject(valueB) && + valueA.equals(valueB) + ); + } + + var imul = + typeof Math.imul === 'function' && Math.imul(0xffffffff, 2) === -2 + ?

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` + +## About + +### Related projects + +* [is-glob](https://www.npmjs.com/package/is-glob): Returns `true` if the given string looks like a glob pattern or an extglob pattern… [more](https://github.com/jonschlinkert/is-glob) | [homepage](https://github.com/jonschlinkert/is-glob "Returns `true` if the given string looks like a glob pattern or an extglob pattern.

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of is more correct than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly tests instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

+ +# liftoff [![Build Status](http://img.shields.io/travis/js-cli/js-liftoff.svg?label=travis-ci)](http://travis-ci.org/js-cli/js-liftoff) [![Build status](https://img.shields.io/appveyor/ci/phated/js-liftoff.svg?label=appveyor)](https://ci.appveyor.com/project/phated/js-liftoff) + + +> Launch your command line tool with ease. + +[![NPM](https://nodei.co/npm/liftoff.png)](https://nodei.co/npm/liftoff/) + +## What is it? +[See this blog post](http://weblog.bocoup.com/building-command-line-tools-in-node-with-liftoff/), [check out this proof of concept](https://github.com/js-cli/js-hacker), or read on. + +Say you're writing a CLI tool. Let's call it [hacker](https://github.com/js-cli/js-hacker). You want to configure it using a `Hackerfile`. This is node, so you install `hacker` locally for each project you use it in. But, in order to get the `hacker` command in your PATH, you also install it globally. + +Now, when you run `hacker`, you want to configure what it does using the `Hackerfile` in your current directory, and you want it to execute using the local installation of your tool. Also, it'd be nice if the `hacker` command was smart enough to traverse up your folders until it finds a `Hackerfile`—for those times when you're not in the root directory of your project. Heck, you might even want to launch `hacker` from a folder outside of your project by manually specifying a working directory. Liftoff manages this for you. + +So, everything is working great. Now you can find your local `hacker` and `Hackerfile` with ease. Unfortunately, it turns out you've authored your `Hackerfile` in coffee-script, or some other JS variant. In order to support *that*, you have to load the compiler for it, and then register the extension for it with node. Good news, Liftoff can do that, and a whole lot more, too. + +## API + +### constructor(opts) + +Create an instance of Liftoff to invoke your application. + +An example utilizing all options: +```js +const Hacker = new Liftoff({ + name: 'hacker', + processTitle: 'hacker', + moduleName: 'hacker', + configName: 'hackerfile', + extensions: { + '.js': null, + '.json': null, + '.coffee': 'coffee-script/register' + }, + v8flags: ['--harmony'] // or v8flags: require('v8flags') +}); +``` + +#### opts.name + +Sugar for setting `processTitle`, `moduleName`, `configName` automatically. + +Type: `String` +Default: `null` + +These are equivalent: +```js +const Hacker = Liftoff({ + processTitle: 'hacker', + moduleName: 'hacker', + configName: 'hackerfile' +}); +``` +```js +const Hacker = Liftoff({name:'hacker'}); +``` + +#### opts.moduleName + +Sets which module your application expects to find locally when being run. + +Type: `String` +Default: `null` + +#### opts.configName + +Sets the name of the configuration file Liftoff will attempt to find. Case-insensitive. + +Type: `String` +Default: `null` + +#### opts.extensions + +Set extensions to include when searching for a configuration file. If an external module is needed to load a given extension (e.g. `.coffee`), the module name should be specified as the value for the key. + +Type: `Object` +Default: `{".js":null,".json":null}` + +**Examples:** + +In this example Liftoff will look for `myappfile{.js,.json,.coffee}`. If a config with the extension `.coffee` is found, Liftoff will try to require `coffee-script/require` from the current working directory. +```js +const MyApp = new Liftoff({ + name: 'myapp', + extensions: { + '.js': null, + '.json': null, + '.coffee': 'coffee-script/register' + } +}); +``` + +In this example, Liftoff will look for `.myapp{rc}`. +```js +const MyApp = new Liftoff({ + name: 'myapp', + configName: '.myapp', + extensions: { + 'rc': null + } +}); +``` + +In this example, Liftoff will automatically attempt to load the correct module for any javascript variant supported by [interpret](https://github.com/js-cli/js-interpret) (as long as it does not require a register method). + +```js +const MyApp = new Liftoff({ + name: 'myapp', + extensions: require('interpret').jsVariants +}); +``` +#### opts.v8flags + +Any flag specified here will be applied to node, not your program. Useful for supporting invocations like `myapp --harmony command`, where `--harmony` should be passed to node, not your program. This functionality is implemented using [flagged-respawn](http://github.com/js-cli/js-flagged-respawn). To support all v8flags, see [v8flags](https://github.com/js-cli/js-v8flags). + +Type: `Array|Function` +Default: `null` + +If this method is a function, it should take a node-style callback that yields an array of flags. + +#### opts.processTitle + +Sets what the [process title](http://nodejs.org/api/process.html#process_process_title) will be. + +Type: `String` +Default: `null` + +#### opts.completions(type) + +A method to handle bash/zsh/whatever completions. + +Type: `Function` +Default: `null` + +#### opts.configFiles + +An object of configuration files to find. Each property is keyed by the default basename of the file being found, and the value is an object of [path arguments](#path-arguments) keyed by unique names. + +__Note:__ This option is useful if, for example, you want to support an `.apprc` file in addition to an `appfile.js`. If you only need a single configuration file, you probably don't need this. In addition to letting you find multiple files, this option allows more fine-grained control over how configuration files are located. + +Type: `Object` +Default: `null` + +#### Path arguments + +The [`fined`](https://github.com/js-cli/fined) module accepts a string representing the path to search or an object with the following keys: + +* `path` __(required)__ + + The path to search. Using only a string expands to this property. + + Type: `String` + Default: `null` + +* `name` + + The basename of the file to find. Extensions are appended during lookup. + + Type: `String` + Default: Top-level key in `configFiles` + +* `extensions` + + The extensions to append to `name` during lookup. See also: [`opts.extensions`](#optsextensions). + + Type: `String|Array|Object` + Default: The value of [`opts.extensions`](#optsextensions) + +* `cwd` + + The base directory of `path` (if relative). + + Type: `String` + Default: The value of [`opts.cwd`](#optscwd) + +* `findUp` + + Whether the `path` should be traversed up to find the file. + + Type: `Boolean` + Default: `false` + +**Examples:** + +In this example Liftoff will look for the `.hacker.js` file relative to the `cwd` as declared in `configFiles`. +```js +const MyApp = new Liftoff({ + name: 'hacker', + configFiles: { + '.hacker': { + cwd: '.' + } + } +}); +``` + +In this example, Liftoff will look for `.hackerrc` in the home directory. +```js +const MyApp = new Liftoff({ + name: 'hacker', + configFiles: { + '.hacker': { + home: { + path: '~', + extensions: { + 'rc': null + } + } + } + } +}); +``` + +In this example, Liftoff will look in the `cwd` and then lookup the tree for the `.hacker.js` file. +```js +const MyApp = new Liftoff({ + name: 'hacker', + configFiles: { + '.hacker': { + up: { + path: '.', + findUp: true + } + } + } +}); +``` + +In this example, the `name` is overridden and the key is ignored so Liftoff looks for `.override.js`. +```js +const MyApp = new Liftoff({ + name: 'hacker', + configFiles: { + hacker: { + override: { + path: '.', + name: '.override' + } + } + } +}); +``` + +In this example, Liftoff will use the home directory as the `cwd` and looks for `~/.hacker.js`. +```js +const MyApp = new Liftoff({ + name: 'hacker', + configFiles: { + '.hacker': { + home: { + path: '.', + cwd: '~' + } + } + } +}); +``` + +### prepare(opts, callback(env)) + +Prepares the environment for your application with provided options, and invokes your callback with the calculated environment as the first argument. The environment can be modified before using it as the first argument to `execute`. + +**Example Configuration w/ Options Parsing:** + +```js +const Liftoff = require('liftoff'); +const MyApp = new Liftoff({name:'myapp'}); +const argv = require('minimist')(process.argv.slice(2)); +const onExecute = function (env, argv) { + // Do post-execute things +}; +const onPrepare = function (env) { + console.log('my environment is:', env); + console.log('my liftoff config is:', this); + MyApp.execute(env, onExecute); +}; +MyApp.prepare({ + cwd: argv.cwd, + configPath: argv.myappfile, + require: argv.require, + completion: argv.completion +}, onPrepare); +``` + +**Example w/ modified environment** + +```js +const Liftoff = require('liftoff'); +const Hacker = new Liftoff({ + name: 'hacker', + configFiles: { + '.hacker': { + home: { path: '.', cwd: '~' } + } + } +}); +const onExecute = function (env, argv) { + // Do post-execute things +}; +const onPrepare = function (env) { + env.configProps = ['home', 'cwd'].map(function(dirname) { + return env.configFiles['.hacker'][dirname] + }).filter(function(filePath) { + return Boolean(filePath); + }).reduce(function(config, filePath) { + return mergeDeep(config, require(filePath)); + }, {}); + + if (env.configProps.hackerfile) { + env.configPath = path.resolve(env.configProps.hackerfile); + env.configBase = path.dirname(env.configPath); + } + + Hacker.execute(env, onExecute); +}; +Hacker.prepare({}, onPrepare); +``` + +#### opts.cwd + +Change the current working directory for this launch.

A good place to modify the environment before calling `execute`. When invoked, `this` will be your instance of Liftoff. The `env` param will contain the following keys: + +- `cwd`: the current working directory +- `require`: an array of modules that liftoff tried to pre-load +- `configNameSearch`: the config files searched for +- `configPath`: the full path to your configuration file (if found) +- `configBase`: the base directory of your configuration file (if found) +- `modulePath`: the full path to the local module your project relies on (if found) +- `modulePackage`: the contents of the local module's package.json (if found) +- `configFiles`: an object of filepaths for each found config file (filepath values will be null if not found) + +### execute(env, [forcedFlags], callback(env, argv)) + +A function to start your application, based on the `env` given. Optionally takes an array of `forcedFlags`, which will force a respawn with those node or V8 flags during startup. Invokes your callback with the environment and command-line arguments (minus node & v8 flags) after the application has been executed. + +**Example:** + +```js +const Liftoff = require('liftoff'); +const MyApp = new Liftoff({name:'myapp'}); +const onExecute = function (env, argv) { + // Do post-execute things + console.log('my environment is:', env); + console.log('my cli options are:', argv); + console.log('my liftoff config is:', this); +}; +const onPrepare = function (env) { + var forcedFlags = ['--trace-deprecation']; + MyApp.execute(env, forcedFlags, onExecute); +}; +MyApp.prepare({}, onPrepare); +``` + +#### callback(env, argv) + +A function called after your application is executed. When invoked, `this` will be your instance of Liftoff, `argv` will be all command-line arguments (minus node & v8 flags), and `env` will contain the following keys: + +- `cwd`: the current working directory +- `require`: an array of modules that liftoff tried to pre-load +- `configNameSearch`: the config files searched for +- `configPath`: the full path to your configuration file (if found) +- `configBase`: the base directory of your configuration file (if found) +- `modulePath`: the full path to the local module your project relies on (if found) +- `modulePackage`: the contents of the local module's package.json (if found) +- `configFiles`: an object of filepaths for each found config file (filepath values will be null if not found) + +### launch(opts, callback(env, argv)) + +**Deprecated:** Please use `prepare` followed by `execute`. That's all this module does internally but those give you more control. + +Launches your application with provided options, builds an environment, and invokes your callback, passing the calculated environment and command-line arguments (minus node & v8 flags) as the arguments. + +Accepts any options that `prepare` allows, plus `opt.forcedFlags`. + +#### opts.forcedFlags + +**Deprecated:** If using `prepare`/`execute`, pass forcedFlags as the 2nd argument instead of using this option. + +Allows you to force node or V8 flags during the launch. This is useful if you need to make sure certain flags will always be enabled or if you need to enable flags that don't show up in `opts.v8flags` (as these flags aren't validated against `opts.v8flags`). + +If this is specified as a function, it will receive the built `env` as its only argument and must return a string or array of flags to force. + +Type: `String|Array|Function` +Default: `null` + +**Example Configuration:** +```js +MyApp.launch({ + forcedFlags: ['--trace-deprecation'] +}, invoke); +``` + +**Matching CLI Invocation:** +```js +myapp --trace-deprecation +``` + +### events + +#### require(name, module) + +Emitted when a module is pre-loaded. + +```js +var Hacker = new Liftoff({name:'hacker'}); +Hacker.on('require', function (name, module) { + console.log('Requiring external module: '+name+'...'); + // automatically register coffee-script extensions + if (name === 'coffee-script') { + module.register(); + } +}); +``` + +#### requireFail(name, err) + +Emitted when a requested module cannot be preloaded. + +```js +var Hacker = new Liftoff({name:'hacker'}); +Hacker.on('requireFail', function (name, err) { + console.log('Unable to load:', name, err); +}); +``` + +#### respawn(flags, child) + +Emitted when Liftoff re-spawns your process (when a [`v8flags`](#optsv8flags) is detected). + +```js +var Hacker = new Liftoff({ + name: 'hacker', + v8flags: ['--harmony'] +}); +Hacker.on('respawn', function (flags, child) { + console.log('Detected node flags:', flags); + console.log('Respawned to PID:', child.pid); +}); +``` + +Event will be triggered for this command: +`hacker --harmony commmand` + +## Examples + +Check out how [gulp](https://github.com/gulpjs/gulp-cli/blob/master/index.js) uses Liftoff. + +For a bare-bones example, try [the hacker project](https://github.com/js-cli/js-hacker/blob/master/bin/hacker.js). + +To try the example, do the following: + +1.

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

In fact, micromatch passes _all of the spec tests_ from bash, including some that bash still fails. +* [Faster matching](#benchmarks), from a combination of optimized glob patterns, faster algorithms, and regex caching. +* [Micromatch is safer](https://github.com/micromatch/braces#braces-is-safe), and is not subject to DoS with brace patterns, like minimatch and multimatch. +* More reliable windows support than minimatch and multimatch. + +### Matching features + +* Support for multiple glob patterns (no need for wrappers like multimatch) +* Wildcards (`**`, `*.js`) +* Negation (`'!a/*.js'`, `'*!(b).js']`) +* [extglobs](https://github.com/micromatch/extglob) (`+(x|y)`, `!(a|b)`) +* [POSIX character classes](https://github.com/micromatch/expand-brackets) (`[[:alpha:][:digit:]]`) +* [brace expansion](https://github.com/micromatch/braces) (`foo/{1..5}.md`, `bar/{a,b,c}.js`) +* regex character classes (`foo-[1-5].js`) +* regex logical "or" (`foo/(abc|xyz).js`) + +You can mix and match these features to create whatever patterns you need! + +## Switching to micromatch + +There is one notable difference between micromatch and minimatch in regards to how backslashes are handled.

In a few cases where Bash had no answers, we used wildmatch (used by git) as a fallback. + +### Backslashes + +There is an important, notable difference between minimatch and micromatch _in regards to how backslashes are handled_ in glob patterns. + +* Micromatch exclusively and explicitly reserves backslashes for escaping characters in a glob pattern, even on windows. This is consistent with bash behavior. +* Minimatch converts all backslashes to forward slashes, which means you can't use backslashes to escape any characters in your glob patterns. + +We made this decision for micromatch for a couple of reasons: + +* consistency with bash conventions. +* glob patterns are not filepaths. They are a type of [regular language](https://en.wikipedia.org/wiki/Regular_language) that is converted to a JavaScript regular expression. Thus, when forward slashes are defined in a glob pattern, the resulting regular expression will match windows or POSIX path separators just fine. + +**A note about joining paths to globs** + +Note that when you pass something like `path.join('foo', '*')` to micromatch, you are creating a filepath and expecting it to still work as a glob pattern. This causes problems on windows, since the `path.sep` is `\\`. + +In other words, since `\\` is reserved as an escape character in globs, on windows `path.join('foo', '*')` would result in `foo\\*`, which tells micromatch to match `*` as a literal character. This is the same behavior as bash. + +## Contributing + +All contributions are welcome!

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

Each item in the row + corresponds to a single path-part. For example, the pattern + `{a,b/c}/d` would expand to a set of patterns like: + + [ [ a, d ] + , [ b, c, d ] ] + + If a portion of the pattern doesn't have any "magic" in it + (that is, it's something like `"foo"` rather than `fo*o?`), then it + will be left as a string rather than converted to a regular + expression. + +* `regexp` Created by the `makeRe` method. A single regular expression + expressing the entire pattern. This is useful in cases where you wish + to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. +* `negate` True if the pattern is negated. +* `comment` True if the pattern is a comment. +* `empty` True if the pattern is `""`. + +### Methods + +* `makeRe` Generate the `regexp` member if necessary, and return it. + Will return `false` if the pattern is invalid. +* `match(fname)` Return true if the filename matches the pattern, or + false otherwise. +* `matchOne(fileArray, patternArray, partial)` Take a `/`-split + filename, and match it against a single row in the `regExpSet`. This + method is mainly for internal use, but is exposed so that it can be + used by a glob-walker that needs to avoid excessive filesystem calls. + +All other methods are internal, and will be called as necessary. + +### minimatch(path, pattern, options) + +Main export. Tests a path against the pattern using the options. + +```javascript +var isJS = minimatch(file, "*.js", { matchBase: true }) +``` + +### minimatch.filter(pattern, options) + +Returns a function that tests its +supplied argument, suitable for use with `Array.filter`. Example: + +```javascript +var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) +``` + +### minimatch.match(list, pattern, options) + +Match against the list of +files, in the style of fnmatch or glob. If nothing is matched, and +options.nonull is set, then return a list containing the pattern itself. + +```javascript +var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) +``` + +### minimatch.makeRe(pattern, options) + +Make a regular expression object from the pattern. + +## Options + +All options are `false` by default. + +### debug + +Dump a ton of stuff to stderr. + +### nobrace + +Do not expand `{a,b}` and `{1..3}` brace sets. + +### noglobstar + +Disable `**` matching against multiple folder names. + +### dot + +Allow patterns to match filenames starting with a period, even if +the pattern does not explicitly have a period in that spot. + +Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` +is set. + +### noext + +Disable "extglob" style patterns like `+(a|b)`. + +### nocase + +Perform a case-insensitive match. + +### nonull + +When a match is not found by `minimatch.match`, return a list containing +the pattern itself if this option is set. When not set, an empty list +is returned if there are no matches. + +### matchBase + +If set, then patterns without slashes will be matched +against the basename of the path if it contains slashes. For example, +`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. + +### nocomment + +Suppress the behavior of treating `#` at the start of a pattern as a +comment. + +### nonegate + +Suppress the behavior of treating a leading `!` character as negation. + +### flipNegate + +Returns from negate expressions the same as if they were not negated. +(Ie, true on a hit, false on a miss.) + +### partial + +Compare a partial path to a pattern. As long as the parts of the path that +are present are not contradicted by the pattern, it will be treated as a +match. This is useful in applications where you're walking through a +folder structure, and don't yet have the full path, but want to ensure that +you do not walk down paths that can never be a match. + +For example, + +```js +minimatch('/a/b', '/a/*/c/d', { partial: true }) // true, might be /a/b/c/d +minimatch('/a/b', '/**/d', { partial: true }) // true, might be /a/b/.../d +minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a +``` + +### allowWindowsEscape + +Windows path separator `\` is by default converted to `/`, which +prohibits the usage of `\` as a escape character. This flag skips that +behavior and allows using the escape character. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between minimatch and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then minimatch.match returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. diff --git a/node_modules/minimatch/minimatch.js b/node_modules/minimatch/minimatch.js new file mode 100644 index 0000000..fda45ad --- /dev/null +++ b/node_modules/minimatch/minimatch.js @@ -0,0 +1,947 @@ +module.exports = minimatch +minimatch.Minimatch = Minimatch + +var path = (function () { try { return require('path') } catch (e) {}}()) || { + sep: '/' +} +minimatch.sep = path.sep + +var GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} +var expand = require('brace-expansion') + +var plTypes = { + '!': { open: '(?:(?!(?:', close: '))[^/]*?)'}, + '?': { open: '(?:', close: ')?' }, + '+': { open: '(?:', close: ')+' }, + '*': { open: '(?:', close: ')*' }, + '@': { open: '(?:', close: ')' } +} + +// any single thing other than / +// don't need to escape / when using new RegExp() +var qmark = '[^/]' + +// * => any number of characters +var star = qmark + '*?' + +// ** when dots are allowed.

+ +## What is nanomatch? + +Nanomatch is a fast and accurate glob matcher with full support for standard Bash glob features, including the following "metacharacters": `*`, `**`, `?` and `[...]`. + +**Learn more** + +* [Getting started](#getting-started): learn how to install and begin using nanomatch +* [Features](#features): jump to info about supported patterns, and a glob matching reference +* [API documentation](#api): jump to available options and methods +* [Unit tests](test): visit unit tests. there is no better way to learn a code library than spending time the unit tests. Nanomatch has 36,000 unit tests - go become a glob matching ninja! + +
+How is this different? + +**Speed and accuracy** + +Nanomatch uses [snapdragon](https://github.com/jonschlinkert/snapdragon) for parsing and compiling globs, which results in: + +* Granular control over the entire conversion process in a way that is easy to understand, reason about, and customize. +* Faster matching, from a combination of optimized glob patterns and (optional) caching. +* Much greater accuracy than minimatch. In fact, nanomatch passes _all of the spec tests_ from bash, including some that bash still fails. However, since there is no real specification for globs, if you encounter a pattern that yields unexpected match results [after researching previous issues](../../issues), [please let us know](../../issues/new). + +**Basic globbing only** + +Nanomatch supports [basic globbing only](#features), which is limited to `*`, `**`, `?` and regex-like brackets. + +If you need support for the other [bash "expansion" types](#bash-expansion-libs) (in addition to the wildcard matching provided by nanomatch), consider using [micromatch](https://github.com/micromatch/micromatch) instead. _(micromatch >=3.0.0 uses the nanomatch parser and compiler for basic glob matching)_ + +
+ +## Getting started + +### Installing nanomatch + +**Install with [yarn](https://yarnpkg.com/)** + +```sh +$ yarn add nanomatch +``` + +**Install with [npm](https://npmjs.com)** + +```sh +$ npm install nanomatch +``` + +### Usage + +Add nanomatch to your project using node's `require()` system: + +```js +var nanomatch = require('nanomatch'); + +// the main export is a function that takes an array of strings to match +// and a string or array of patterns to use for matching +nanomatch(list, patterns[, options]); +``` + +**Params** + +* `list` **{String|Array}**: List of strings to perform matches against. This is often a list of file paths. +* `patterns` **{String|Array}**: One or more [glob paterns](#features) to use for matching. +* `options` **{Object}**: Any [supported options](#options) may be passed + +**Examples** + +```js +var nm = require('nanomatch'); +console.log(nm(['a', 'b/b', 'c/c/c'], '*')); +//=> ['a'] + +console.log(nm(['a', 'b/b', 'c/c/c'], '*/*')); +//=> ['b/b'] + +console.log(nm(['a', 'b/b', 'c/c/c'], '**')); +//=> ['a', 'b/b', 'c/c/c'] +``` + +See the [API documentation](#api) for available methods and [options](https://github.com/einaros/options.js). + +## Documentation + +### Escaping + +_Backslashes and quotes_ can be used to escape characters, forcing nanomatch to regard those characters as a literal characters. + +**Backslashes** + +Use backslashes to escape single characters. For example, the following pattern would match `foo/*/bar` exactly: + +```js +'foo/\*/bar' +``` + +The following pattern would match `foo/` followed by a literal `*`, followed by zero or more of any characters besides `/`, followed by `/bar`. + +```js +'foo/\**/bar' +``` + +**Quoted strings** + +Use single or double quotes to escape sequences of characters. For example, the following patterns would match `foo/**/bar` exactly: + +```js +'foo/"**"/bar' +'foo/\'**\'/bar' +"foo/'**'/bar" +``` + +**Matching literal quotes** + +If you need to match quotes literally, you can escape them as well. For example, the following will match `foo/"*"/bar`, `foo/"a"/bar`, `foo/"b"/bar`, or `foo/"c"/bar`: + +```js +'foo/\\"*\\"/bar' +``` + +And the following will match `foo/'*'/bar`, `foo/'a'/bar`, `foo/'b'/bar`, or `foo/'c'/bar`: + +```js +'foo/\\\'*\\\'/bar' +``` + +## API + +### [nanomatch](index.js#L40) + +The main function takes a list of strings and one or more glob patterns to use for matching. + +**Params** + +* `list` **{Array}**: A list of strings to match +* `patterns` **{String|Array}**: One or more glob patterns to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Array}**: Returns an array of matches + +**Example** + +```js +var nm = require('nanomatch'); +nm(list, patterns[, options]); + +console.log(nm(['a.js', 'a.txt'], ['*.js'])); +//=> [ 'a.js' ] +``` + +### [.match](index.js#L106) + +Similar to the main function, but `pattern` must be a string. + +**Params** + +* `list` **{Array}**: Array of strings to match +* `pattern` **{String}**: Glob pattern to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Array}**: Returns an array of matches + +**Example** + +```js +var nm = require('nanomatch'); +nm.match(list, pattern[, options]); + +console.log(nm.match(['a.a', 'a.aa', 'a.b', 'a.c'], '*.a')); +//=> ['a.a', 'a.aa'] +``` + +### [.isMatch](index.js#L167) + +Returns true if the specified `string` matches the given glob `pattern`. + +**Params** + +* `string` **{String}**: String to match +* `pattern` **{String}**: Glob pattern to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Boolean}**: Returns true if the string matches the glob pattern. + +**Example** + +```js +var nm = require('nanomatch'); +nm.isMatch(string, pattern[, options]); + +console.log(nm.isMatch('a.a', '*.a')); +//=> true +console.log(nm.isMatch('a.b', '*.a')); +//=> false +``` + +### [.some](index.js#L205) + +Returns true if some of the elements in the given `list` match any of the given glob `patterns`. + +**Params** + +* `list` **{String|Array}**: The string or array of strings to test.

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of seems to be more consistently "correct" than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly identifies instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

This data is typically found in a package.json file, but in principle could come from any source - for example the npm registry. + +normalize-package-data is used by [read-package-json](https://npmjs.org/package/read-package-json) to normalize the data it reads from a package.json file. In turn, read-package-json is used by [npm](https://npmjs.org/package/npm) and various npm-related tools. + +## Installation + +``` +npm install normalize-package-data +``` + +## Usage + +Basic usage is really simple. You call the function that normalize-package-data exports. Let's call it `normalizeData`. + +```javascript +normalizeData = require('normalize-package-data') +packageData = require("./package.json") +normalizeData(packageData) +// packageData is now normalized +``` + +#### Strict mode + +You may activate strict validation by passing true as the second argument. + +```javascript +normalizeData = require('normalize-package-data') +packageData = require("./package.json") +normalizeData(packageData, true) +// packageData is now normalized +``` + +If strict mode is activated, only Semver 2.0 version strings are accepted. Otherwise, Semver 1.0 strings are accepted as well. Packages must have a name, and the name field must not have contain leading or trailing whitespace. + +#### Warnings + +Optionally, you may pass a "warning" function. It gets called whenever the `normalizeData` function encounters something that doesn't look right. It indicates less than perfect input data. + +```javascript +normalizeData = require('normalize-package-data') +packageData = require("./package.json") +warnFn = function(msg) { console.error(msg) } +normalizeData(packageData, warnFn) +// packageData is now normalized. Any number of warnings may have been logged. +``` + +You may combine strict validation with warnings by passing `true` as the second argument, and `warnFn` as third. + +When `private` field is set to `true`, warnings will be suppressed. + +### Potential exceptions + +If the supplied data has an invalid name or version vield, `normalizeData` will throw an error. Depending on where you call `normalizeData`, you may want to catch these errors so can pass them to a callback. + +## What normalization (currently) entails + +* The value of `name` field gets trimmed (unless in strict mode). +* The value of the `version` field gets cleaned by `semver.clean`. See [documentation for the semver module](https://github.com/isaacs/node-semver). +* If `name` and/or `version` fields are missing, they are set to empty strings. +* If `files` field is not an array, it will be removed. +* If `bin` field is a string, then `bin` field will become an object with `name` set to the value of the `name` field, and `bin` set to the original string value. +* If `man` field is a string, it will become an array with the original string as its sole member. +* If `keywords` field is string, it is considered to be a list of keywords separated by one or more white-space characters. It gets converted to an array by splitting on `\s+`. +* All people fields (`author`, `maintainers`, `contributors`) get converted into objects with name, email and url properties. +* If `bundledDependencies` field (a typo) exists and `bundleDependencies` field does not, `bundledDependencies` will get renamed to `bundleDependencies`. +* If the value of any of the dependencies fields (`dependencies`, `devDependencies`, `optionalDependencies`) is a string, it gets converted into an object with familiar `name=>value` pairs. +* The values in `optionalDependencies` get added to `dependencies`. The `optionalDependencies` array is left untouched. +* As of v2: Dependencies that point at known hosted git providers (currently: github, bitbucket, gitlab) will have their URLs canonicalized, but protocols will be preserved. +* As of v2: Dependencies that use shortcuts for hosted git providers (`org/proj`, `github:org/proj`, `bitbucket:org/proj`, `gitlab:org/proj`, `gist:docid`) will have the shortcut left in place. (In the case of github, the `org/proj` form will be expanded to `github:org/proj`.) THIS MARKS A BREAKING CHANGE FROM V1, where the shorcut was previously expanded to a URL. +* If `description` field does not exist, but `readme` field does, then (more or less) the first paragraph of text that's found in the readme is taken as value for `description`. +* If `repository` field is a string, it will become an object with `url` set to the original string value, and `type` set to `"git"`. +* If `repository.url` is not a valid url, but in the style of "[owner-name]/[repo-name]", `repository.url` will be set to git+https://github.com/[owner-name]/[repo-name].git +* If `bugs` field is a string, the value of `bugs` field is changed into an object with `url` set to the original string value. +* If `bugs` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `bugs` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]/issues . If the repository field points to a GitHub Gist repo url, the associated http url is chosen. +* If `bugs` field is an object, the resulting value only has email and url properties. If email and url properties are not strings, they are ignored. If no valid values for either email or url is found, bugs field will be removed. +* If `homepage` field is not a string, it will be removed. +* If the url in the `homepage` field does not specify a protocol, then http is assumed. For example, `myproject.org` will be changed to `http://myproject.org`. +* If `homepage` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `homepage` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]#readme . If the repository field points to a GitHub Gist repo url, the associated http url is chosen. + +### Rules for name field + +If `name` field is given, the value of the name field must be a string. The string may not: + +* start with a period. +* contain the following characters: `/@\s+%` +* contain any characters that would need to be encoded for use in urls. +* resemble the word `node_modules` or `favicon.ico` (case doesn't matter). + +### Rules for version field + +If `version` field is given, the value of the version field must be a valid *semver* string, as determined by the `semver.valid` method. See [documentation for the semver module](https://github.com/isaacs/node-semver). + +### Rules for license field + +The `license` field should be a valid *SPDX license expression* or one of the special values allowed by [validate-npm-package-license](https://npmjs.com/package/validate-npm-package-license).

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` +4. There is no reason to make the code in a microlib as terse as possible, just to win points for making it shorter. It's always better to favor performant code over terse code. You will always only be using a single `require()` statement to use the library anyway, regardless of how the code is written. + +## Better type checking + +kind-of is more correct than other type checking libs I've looked at. For example, here are some differing results from other popular libs: + +### [typeof](https://github.com/CodingFu/typeof) lib + +Incorrectly tests instances of custom constructors (pretty common): + +```js +var typeOf = require('typeof'); +function Test() {} +console.log(typeOf(new Test())); +//=> 'test' +``` + +Returns `object` instead of `arguments`: + +```js +function foo() { + console.log(typeOf(arguments)) //=> 'object' +} +foo(); +``` + +### [type-of](https://github.com/ForbesLindesay/type-of) lib + +Incorrectly returns `object` for generator functions, buffers, `Map`, `Set`, `WeakMap` and `WeakSet`: + +```js +function * foo() {} +console.log(typeOf(foo)); +//=> 'object' +console.log(typeOf(new Buffer(''))); +//=> 'object' +console.log(typeOf(new Map())); +//=> 'object' +console.log(typeOf(new Set())); +//=> 'object' +console.log(typeOf(new WeakMap())); +//=> 'object' +console.log(typeOf(new WeakSet())); +//=> 'object' +``` + +## About + +

There are a few things that lead to this performance advantage, none of them hard and fast rules, but all of them simple and repeatable in almost any code library: + +1. Optimize around the fastest and most common use cases first. Of course, this will change from project-to-project, but I took some time to understand how and why `typeof` checks were being used in my own libraries and other libraries I use a lot. +2. Optimize around bottlenecks - In other words, the order in which conditionals are implemented is significant, because each check is only as fast as the failing checks that came before it. Here, the biggest bottleneck by far is checking for plain objects (an object that was created by the `Object` constructor). I opted to make this check happen by process of elimination rather than brute force up front (e.g. by using something like `val.constructor.name`), so that every other type check would not be penalized it. +3. Don't do uneccessary processing - why do `.slice(8, -1).toLowerCase();` just to get the word `regex`? It's much faster to do `if (type === '[object RegExp]') return 'regex'` + +## About + +### Related projects + +* [is-glob](https://www.npmjs.com/package/is-glob): Returns `true` if the given string looks like a glob pattern or an extglob pattern… [more](https://github.com/jonschlinkert/is-glob) | [homepage](https://github.com/jonschlinkert/is-glob "Returns `true` if the given string looks like a glob pattern or an extglob pattern.

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh

+
+## Usage
+
+```js
+var mapValues = require('object.map');
+
+var result = mapValues({a: 'a', b: 'b'}, function(val, key, obj) {
+  return val + val;
+});
+console.log(result);

+
+Optionally specify a `thisArg` as the last argument:
+
+```js
+var result = mapValues({a: 'b'}, function(val, key, obj) {
+  return this.foo;
+}, {foo: 'bar'});
+console.log(result);
+//=> {a: 'bar'}

+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save object.pick
+```
+
+## benchmarks
+
+This is the [fastest implementation](http://jsperf.com/pick-props) I tested. Pull requests welcome!
+
+## Usage
+
+```js
+var pick = require('object.pick');
+
+pick({a: 'a', b: 'b'}, 'a')
+//=> {a: 'a'}
+
+pick({a: 'a', b: 'b', c: 'c'}, ['a', 'b'])
+//=> {a: 'a', b: 'b'}

+
+> Reduces an object to a value that is the accumulated result of running each property in the object through a callback.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save object.reduce
+```
+
+Install with [yarn](https://yarnpkg.com):
+
+```sh
+$ yarn add object.reduce
+```
+
+Install with [bower](https://bower.io/)
+
+```sh
+$ bower install object.reduce --save
+```
+
+## Usage
+
+the initial value (or value from the previous callback call), the `value` of the current property, the `key` of the current property, and the `object` over which the function is iterating. Node.js/JavaScript utility.)_
+
+**Params**
+
+* `object` **{Object}**: The object to iterate over (the iteratee)
+* `fn` **{Function}**: The function invoked per iteration.
+* `init` **{Object}**: The initial value to use for the accumulator.
+* `thisArg` **{Object}**: (optional) Object to use as the invocation context for the iterator (expose as `this` inside the iterator)
+
+Executes the given callback `fn` once for each own enumerable property in the object. The callback receives the following arguments:
+
+* `acc`: the initial value (or value from the previous callback call),
+* `value`: the of the current property,
+* `key`: the of the current property, and
+* the original `object` over which the function is iterating.
+
+**Example**
+
+```js
+var reduce = require('object.reduce');
+var a = {a: 'foo', b: 'bar', c: 'baz'};
+
+reduce(a, function(acc, value, key, obj) {
+  acc[key] = value.toUpperCase();
+  return acc;
+}, {});
+
+//=> {a: 'FOO', b: 'BAR', c: 'BAZ'};
+```

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+
+Combines array of streams into one read stream in strict order.
+
+## Installation
+
+`npm install ordered-read-streams`
+
+## Overview
+
+`ordered-read-streams` handles all data/errors from input streams in parallel, but emits data/errors in strict order in which streams are passed to constructor. This is `objectMode = true` stream.
+
+## Example
+
+```js
+var through = require('through2');
+var Ordered = require('ordered-read-streams');
+
+var s1 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 200)
+});
+var s2 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 30)
+});
+var s3 = through.obj(function (data, enc, next) {
+  var self = this;
+  setTimeout(function () {
+    self.push(data);
+    next();
+  }, 100)
+});
+
+var streams = new Ordered([s1, s2, s3]);
+streams.on('data', function (data) {
+  console.log(data);
+})
+
+s1.write('stream 1');
+s1.end();
+
+s2.write('stream 2');
+s2.end();
+
+s3.write('stream 3');

+
+> Get the system [locale](http://en.wikipedia.org/wiki/Locale)
+
+Useful for localizing your module or app.
+
+POSIX systems: The returned locale refers to the [`LC_MESSAGE`](http://www.gnu.org/software/libc/manual/html_node/Locale-Categories.html#Locale-Categories) category, suitable for selecting the language used in the user interface for message translation.
+
+
+## Install
+
+```
+$ npm install --save os-locale
+```
+
+
+## Usage
+
+```js
+var osLocale = require('os-locale');
+
+osLocale(function (err, locale) {
+	console.log(locale);
+	//=> 'en_US'
+});
+```
+
+
+## API
+
+### osLocale([options], callback(error, locale))
+
+### osLocale.sync([options])
+
+Returns the locale.
+
+#### options.spawn
+
+Type: `boolean`  
+Default: `true`
+
+Set to `false` to avoid spawning subprocesses and instead only resolve the locale from environment variables.

+
+> Pollyfill for node.js `path.parse`, parses a filepath into an object.
+
+You might also be interested in [global-prefix](https://github.com/jonschlinkert/global-prefix).
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install parse-filepath --save
+```
+
+## Usage
+
+```js
+var parsePath = require('parse-filepath');
+parsePath(filepath);
+```
+
+This can be used as a polyfill for the native node.js `path.parse()` method, and it also adds a few properties:
+
+* `path`: the original filepath
+* `isAbsolute`: (getter) true if the given path is absolute
+* `absolute`: (getter) fully resolved, absolute filepath
+* `dirname`: alias for `dir`
+* `basename`: alias for `base`
+* `extname`: alias for `ext`
+* `stem`: alias for `name`
+
+**Example**
+
+```js
+var parsePath = require('parse-filepath');
+console.log(parsePath('foo/bar/baz/index.js'));
+```
+
+Returns:
+
+```js
+{ root: '',
+  dir: 'foo/bar/baz',
+  base: 'index.js',
+  ext: '.js',
+  name: 'index',
+
+  // aliases
+  extname: '.js',
+  basename: 'index.js',
+  dirname: 'foo/bar/baz',
+  stem: 'index',
+
+  // original path
+  path: 'foo/bar/baz/index.js',
+
+  // getters
+  absolute: [Getter/Setter],
+  isAbsolute: [Getter/Setter] }
+```

+
+parseJson(json, 'foo.json');
+/*
+JSONError: Trailing comma in object at 3:1 in foo.json
+}
+^
+*/
+
+
+// you can also add the filename at a later point

+
+Turn node's process.version into something useful.
+
+## Usage
+
+```js
+var nodeVersion = require('parse-node-version')(process.version);
+
+console.log(
+  nodeVersion.major,
+  nodeVersion.minor,
+  nodeVersion.patch,
+  nodeVersion.pre,
+  nodeVersion.build
+);
+```
+
+## API
+
+### parseVersion(nodeVersionString)
+
+Takes a node version string (usually `process.version`) and returns an object with the `major`/`minor`/`patch` (which will all be numbers) and `pre`/`build` keys (which will always be a string). If the version doesn't contain any pre-release or build information, the properties will be returned as empty string.

+# path-exists [![Build Status](https://travis-ci.org/sindresorhus/path-exists.svg?branch=master)](https://travis-ci.org/sindresorhus/path-exists)
+
+> Check if a path exists
+
+Because [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), but there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it.
+
+Never use this before handling a file though:
+
+> In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
+
+
+## Install
+
+```
+$ npm install --save path-exists
+```
+
+
+## Usage
+
+```js
+// foo.js
+var pathExists = require('path-exists');
+
+pathExists('foo.js').then(function (exists) {
+	console.log(exists);
+	//=> true
+});
+```
+
+
+## API
+
+### pathExists(path)
+
+Returns a promise that resolves to a boolean of whether the path exists.
+
+### pathExists.sync(path)
+
+Returns a boolean of whether the path exists.

+> Regular expression for getting the root of a posix or windows filepath.
+
+You might also be interested in [path-root](https://github.com/jonschlinkert/path-root).
+
+## Usage
+
+The module exposes a function that must be called to get the regex (modified from the split device regex in the node.js path module);
+
+```js
+var pathRootRegex = require('path-root-regex');
+
+console.log(pathRootRegex() instanceof RegExp);
+//=> true
+```
+
+See the [path-root](https://github.com/jonschlinkert/path-root) module for examples.

+
+

+Blazing fast and accurate glob matcher written in JavaScript.

+No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.
+

+
+

+

+
+## Why picomatch?
+
+* **Lightweight** - No dependencies
+* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
+* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
+* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
+* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
+* **Well tested** - Thousands of unit tests
+
+See the [library comparison](#library-comparisons) to other libraries.

+
+## Usage
+
+The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
+
+```js
+const pm = require('picomatch');
+const isMatch = pm('*.js');
+
+console.log(isMatch('abcd')); //=> false
+console.log(isMatch('a.js')); //=> true

+## API
+
+### [picomatch](lib/picomatch.js#L32)
+
+Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match.

+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+// picomatch(glob[, options]);
+
+const isMatch = picomatch('*.!(*a)');
+console.log(isMatch('a.a')); //=> false
+console.log(isMatch('a.b')); //=> true
+```
+
+### [.test](lib/picomatch.js#L117)
+
+Test `input` with the given `regex`. This is used by the main `picomatch()` function to test the input string.
+
+**Params**

+const picomatch = require('picomatch');
+// picomatch.test(input, regex[, options]);
+
+console.log(picomatch.test('foo/bar', /^(?:([^/]*?)\/([^/]*?))$/));
+// { isMatch: true, match: [ 'foo/', 'foo', 'bar' ], output: 'foo/bar' }
+```
+
+### [.matchBase](lib/picomatch.js#L161)
+
+Match the basename of a filepath.
+
+**Params**
+
+* `input` **{String}**: String to test.
+* `glob` **{RegExp|String}**: Glob pattern or regex created by [.makeRe](#makeRe).
+* `returns` **{Boolean}**
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+// picomatch.matchBase(input, glob[, options]);
+console.log(picomatch.matchBase('foo/bar.js', '*.js'); // true
+```
+
+### [.isMatch](lib/picomatch.js#L183)
+
+Returns true if **any** of the given glob `patterns` match the specified `string`.
+
+**Params**
+
+* **{String|Array}**: str The string to test.
+* **{String|Array}**: patterns One or more glob patterns to use for matching.
+* **{Object}**: See available [options](#options).
+* `returns` **{Boolean}**: Returns true if any patterns match `str`
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+// picomatch.isMatch(string, patterns[, options]);
+
+console.log(picomatch.isMatch('a.a', ['b.*', '*.a'])); //=> true
+console.log(picomatch.isMatch('a.a', 'b.*')); //=> false
+```
+
+### [.parse](lib/picomatch.js#L199)
+
+Parse a glob pattern to create the source string for a regular expression.
+
+**Params**
+
+* `pattern` **{String}**
+* `options` **{Object}**
+* `returns` **{Object}**: Returns an object with useful properties and output to be used as a regex source string.
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+const result = picomatch.parse(pattern[, options]);
+```
+
+### [.scan](lib/picomatch.js#L231)
+
+Scan a glob pattern to separate the pattern into segments.
+
+**Params**
+
+* `input` **{String}**: Glob pattern to scan.
+* `options` **{Object}**
+* `returns` **{Object}**: Returns an object with
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+// picomatch.scan(input[, options]);
+
+const result = picomatch.scan('!./foo/*.js');
+console.log(result);
+{ prefix: '!./',
+  input: '!./foo/*.js',
+  start: 3,
+  base: 'foo',
+  glob: '*.js',
+  isBrace: false,
+  isBracket: false,
+  isGlob: true,
+  isExtglob: false,
+  isGlobstar: false,
+  negated: true }
+```
+
+### [.compileRe](lib/picomatch.js#L245)
+
+Compile a regular expression from the `state` object returned by the
+[parse()](#parse) method.
+
+**Params**
+
+* `state` **{Object}**

+| --- | --- | --- | --- |
+| `basename`            | `boolean`      | `false`     | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes.  For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
+| `bash`                | `boolean`      | `false`     | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
+| `capture`             | `boolean`      | `undefined` | Return regex matches in supporting methods. |
+| `contains`            | `boolean`      | `undefined` | Allows glob to match any part of the given string(s). |
+| `cwd`                 | `string`       | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
+| `debug`               | `boolean`      | `undefined` | Debug regular expressions when an error is thrown. |
+| `dot`                 | `boolean`      | `false`     | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
+| `expandRange`         | `function`     | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
+| `failglob`            | `boolean`      | `false`     | Throws an error if no matches are found. Based on the bash option of the same name. |
+| `fastpaths`           | `boolean`      | `true`      | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
+| `flags`               | `string`      | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
+| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
+| `ignore`              | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
+| `keepQuotes`          | `boolean`      | `false`     | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes.  |
+| `literalBrackets`     | `boolean`      | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
+| `matchBase`           | `boolean`      | `false`     | Alias for `basename` |
+| `maxLength`           | `boolean`      | `65536`     | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
+| `nobrace`             | `boolean`      | `false`     | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
+| `nobracket`           | `boolean`      | `undefined` | Disable matching with regex brackets. |
+| `nocase`              | `boolean`      | `false`     | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
+| `nodupes`             | `boolean`      | `true`      | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
+| `noext`               | `boolean`      | `false`     | Alias for `noextglob` |
+| `noextglob`           | `boolean`      | `false`     | Disable support for matching with extglobs (like `+(a\|b)`) |
+| `noglobstar`          | `boolean`      | `false`     | Disable support for matching nested directories with globstars (`**`) |
+| `nonegate`            | `boolean`      | `false`     | Disable support for negating with leading `!` |
+| `noquantifiers`       | `boolean`      | `false`     | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. |
+| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. |
+| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. |
+| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. |
+| `posix`               | `boolean`      | `false`     | Support POSIX character classes ("posix brackets"). |
+| `posixSlashes`        | `boolean`      | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself |
+| `prepend`             | `boolean`      | `undefined` | String to prepend to the generated regex used for matching. |
+| `regex`               | `boolean`      | `false`     | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). |
+| `strictBrackets`      | `boolean`      | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. |
+| `strictSlashes`       | `boolean`      | `undefined` | When true, picomatch won't match trailing slashes with single stars. |
+| `unescape`            | `boolean`      | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. |
+| `unixify`             | `boolean`      | `undefined` | Alias for `posixSlashes`, for backwards compatibility. |
+
+picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
+
+### Scan Options
+
+In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
+| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+const result = picomatch.scan('!./foo/*.js', { tokens: true });
+console.log(result);
+// {
+//   prefix: '!./',
+//   input: '!./foo/*.js',
+//   start: 3,
+//   base: 'foo',
+//   glob: '*.js',
+//   isBrace: false,
+//   isBracket: false,
+//   isGlob: true,
+//   isExtglob: false,
+//   isGlobstar: false,
+//   negated: true,
+//   maxDepth: 2,
+//   tokens: [
+//     { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
+//     { value: 'foo', depth: 1, isGlob: false },
+//     { value: '*.js', depth: 1, isGlob: true }
+//   ],
+//   slashes: [ 2, 6 ],
+//   parts: [ 'foo', '*.js' ]
+// }
+```
+
+

+
+### Options Examples
+
+#### options.expandRange
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
+
+**Example**
+
+The following example shows how to create a glob that matches a folder
+
+```js
+const fill = require('fill-range');
+const regex = pm.makeRe('foo/{01..25}/bar', {
+  expandRange(a, b) {
+    return `(${fill(a, b, { toRegex: true })})`;
+  }
+});
+
+console.log(regex);
+//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
+
+console.log(regex.test('foo/00/bar'))  // false
+console.log(regex.test('foo/01/bar'))  // true
+console.log(regex.test('foo/10/bar')) // true
+console.log(regex.test('foo/22/bar')) // true
+console.log(regex.test('foo/25/bar')) // true
+console.log(regex.test('foo/26/bar')) // false
+```
+
+#### options.format
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for formatting strings before they're matched.
+
+**Example**
+
+```js
+// strip leading './' from strings
+const format = str => str.replace(/^\.\//, '');
+const isMatch = picomatch('foo/*.js', { format });
+console.log(isMatch('./foo/bar.js')); //=> true
+```
+
+#### options.onMatch
+
+```js
+const onMatch = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onMatch });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onIgnore
+
+```js
+const onIgnore = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onResult
+
+```js
+const onResult = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onResult, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+

+
+## Globbing features
+
+* [Basic globbing](#basic-globbing) (Wildcard matching)
+* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
+
+### Basic globbing
+
+| **Character** | **Description** |
+| --- | --- |
+| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
+| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
+| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots.  |
+| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
+
+#### Matching behavior vs. Bash
+
+Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
+
+* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
+* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
+
+

+
+### Advanced globbing
+
+* [extglobs](#extglobs)
+* [POSIX brackets](#posix-brackets)
+* [Braces](#brace-expansion)
+
+#### Extglobs
+
+| **Pattern** | **Description** |
+| --- | --- |
+| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
+| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
+| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
+| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
+| `!(pattern)` | Match _anything but_ `pattern` |
+
+**Examples**
+
+```js
+const pm = require('picomatch');
+
+// *(pattern) matches ZERO or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// +(pattern) matches ONE or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// supports multiple extglobs
+console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
+
+// supports nested extglobs
+console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
+```
+
+#### POSIX brackets
+
+POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
+
+**Enable POSIX bracket support**
+
+```js
+console.log(pm.makeRe('[[:word:]]+', { posix: true }));
+//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
+```
+
+**Supported POSIX classes**
+
+The following named POSIX bracket expressions are supported:
+
+* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
+* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
+* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
+* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
+* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
+* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
+* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
+* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
+* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
+* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
+* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
+* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
+* `[:word:]` -  Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
+* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
+
+See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
+
+### Braces
+
+Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
+
+### Matching special characters as literals
+
+If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
+
+**Special Characters**
+
+Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
+
+To match any of the following characters as literals: `$^*+?()[]
+
+Examples:
+
+```js
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+```
+
+

+

+
+## Philosophies
+
+The goal of this library is to be blazing fast, without compromising on accuracy.
+
+**Accuracy**
+
+The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
+
+Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
+
+**Performance**
+
+Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

+# pify [![Build Status](https://travis-ci.org/sindresorhus/pify.svg?branch=master)](https://travis-ci.org/sindresorhus/pify)
+
+> Promisify a callback-style function
+
+
+## Install
+
+```
+$ npm install --save pify
+```
+
+
+## Usage
+
+```js
+const fs = require('fs');
+const pify = require('pify');
+
+// promisify a single function
+
+pify(fs.readFile)('package.json', 'utf8').then(data => {
+	console.log(JSON.parse(data).name);
+	//=> 'pify'
+});
+
+// or promisify all methods in a module
+
+pify(fs).readFile('package.json', 'utf8').then(data => {
+	console.log(JSON.parse(data).name);
+	//=> 'pify'
+});
+```
+
+
+## API
+
+### pify(input, [promiseModule], [options])
+
+Returns a promise wrapped version of the supplied function or module.
+
+#### input
+
+Type: `function`, `object`
+
+Callback-style function or module whose methods you want to promisify.
+
+#### promiseModule
+
+Type: `function`
+
+Custom promise module to use instead of the native one.
+
+Check out [`pinkie-promise`](https://github.com/floatdrop/pinkie-promise) if you need a tiny promise polyfill.
+
+#### options
+
+##### multiArgs
+
+Type: `boolean`  
+Default: `false`
+
+By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like `request` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument.
+
+```js
+const request = require('request');
+const pify = require('pify');
+
+pify(request, {multiArgs: true})('https://sindresorhus.com').then(result => {
+	const [httpResponse, body] = result;
+});
+```
+
+##### include
+
+Type: `array` of (`string`|`regex`)
+
+Methods in a module to promisify. Remaining methods will be left untouched.
+
+##### exclude
+
+Type: `array` of (`string`|`regex`)  
+Default: `[/.+Sync$/]`
+
+Methods in a module **not** to promisify. Methods with names ending with `'Sync'` are excluded by default.
+
+##### excludeMain
+
+Type: `boolean`  
+Default: `false`
+
+By default, if given module is a function itself, this function will be promisified. Turn this option on if you want to promisify only methods of the module.
+
+```js
+const pify = require('pify');
+
+function fn() {
+	return true;
+}
+
+fn.method = (data, callback) => {
+	setImmediate(() => {
+		callback(data, null);
+	});
+};
+
+// promisify methods but not fn()
+const promiseFn = pify(fn, {excludeMain: true});
+
+if (promiseFn()) {
+	promiseFn.method('hi').then(data => {
+		console.log(data);
+	});
+}
+```

+> Itty bitty little widdle twinkie pinkie [ES2015 Promise](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-objects) implementation
+
+[![Build Status](https://travis-ci.org/floatdrop/pinkie.svg?branch=master)](https://travis-ci.org/floatdrop/pinkie)  [![Coverage Status](https://coveralls.io/repos/floatdrop/pinkie/badge.svg?branch=master&service=github)](https://coveralls.io/github/floatdrop/pinkie?branch=master)
+
+There are [tons of Promise implementations](https://github.com/promises-aplus/promises-spec/blob/master/implementations.md#standalone) out there, but all of them focus on browser compatibility and are often bloated with functionality.
+
+This module is an exact Promise specification polyfill (like [native-promise-only](https://github.com/getify/native-promise-only)), but in Node.js land (it should be browserify-able though).
+
+
+## Install
+
+```
+$ npm install --save pinkie
+```
+
+
+## Usage
+
+```js
+var fs = require('fs');
+var Promise = require('pinkie');
+
+new Promise(function (resolve, reject) {
+	fs.readFile('foo.json', 'utf8', function (err, data) {
+		if (err) {
+			reject(err);
+			return;
+		}
+
+		resolve(data);
+	});
+});
+//=> Promise
+```
+
+
+### API
+
+`pinkie` exports bare [ES2015 Promise](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-objects) implementation and polyfills [Node.js rejection events](https://nodejs.org/api/process.html#process_event_unhandledrejection). In case you forgot:
+
+#### new Promise(executor)
+
+Returns new instance of `Promise`.
+
+##### executor
+
+*Required*  
+Type: `function`
+
+Function with two arguments `resolve` and `reject`. The first argument fulfills the promise, the second argument rejects it.
+
+#### pinkie.all(promises)
+
+Returns a promise that resolves when all of the promises in the `promises` Array argument have resolved.
+
+#### pinkie.race(promises)
+
+Returns a promise that resolves or rejects as soon as one of the promises in the `promises` Array resolves or rejects, with the value or reason from that promise.
+
+#### pinkie.reject(reason)
+
+Returns a Promise object that is rejected with the given `reason`.
+
+#### pinkie.resolve(value)
+
+Returns a Promise object that is resolved with the given `value`. If the `value` is a thenable (i.e. has a then method), the returned promise will "follow" that thenable, adopting its eventual state; otherwise the returned promise will be fulfilled with the `value`.

+
+Error handling for Vinyl plugins.
+
+## Usage
+
+```js
+var PluginError = require('plugin-error');
+
+var err = new PluginError('test', {
+  message: 'something broke'
+});
+
+var err = new PluginError({
+  plugin: 'test',
+  message: 'something broke'
+});
+
+var err = new PluginError('test', 'something broke');
+
+var err = new PluginError('test', 'something broke', { showStack: true });
+
+var existingError = new Error('OMG');
+var err = new PluginError('test', existingError, { showStack: true });
+```
+
+## API
+
+### `new PluginError(pluginName, message[, options])`
+
+Error constructor that takes:
+* `pluginName` - a `String` that should be the module name of your plugin
+* `message` - a `String` message or an existing `Error` object
+* `options` - an `Object` of your options
+
+**Behavior:**
+
+* By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
+* If you pass an error object as the message the stack will be pulled from that, otherwise one will be created.
+* If you pass in a custom stack string you need to include the message along with that.
+* Error properties will be included in `err.toString()`, but may be omitted by including `{ showProperties: false }` in the options.

+
+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable

+
+> POSIX character classes for creating regular expressions.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save posix-character-classes
+```
+
+Install with [yarn](https://yarnpkg.com):
+
+```sh
+$ yarn add posix-character-classes
+```
+
+## Usage
+
+```js
+var posix = require('posix-character-classes');
+console.log(posix.alpha);
+//=> 'A-Za-z'
+```
+
+## POSIX Character classes
+
+The POSIX standard supports the following classes or categories of charactersh (note that classes must be defined within brackets)[1]:
+
+| **POSIX class** | **Equivalent to** | **Matches** | 
+| --- | --- | --- |
+| `[:alnum:]` | `[A-Za-z0-9]` | digits, uppercase and lowercase letters |
+| `[:alpha:]` | `[A-Za-z]` | upper- and lowercase letters |
+| `[:ascii:]` | `[\x00-\x7F]` | ASCII characters |
+| `[:blank:]` | `[ \t]` | space and TAB characters only |
+| `[:cntrl:]` | `[\x00-\x1F\x7F]` | Control characters |
+| `[:digit:]` | `[0-9]` | digits |
+| `[:graph:]` | `[^[:cntrl:]]` | graphic characters (all characters which have graphic representation) |
+| `[:lower:]` | `[a-z]` | lowercase letters |
+| `[:print:]` | `[[:graph] ]` | graphic characters and space |
+| `[:punct:]` | ``[-!"#$%&'()*+,./:;<=>?@[]^_`{ | }~]`` | all punctuation characters (all graphic characters except letters and digits) |
+| `[:space:]` | `[ \t\n\r\f\v]` | all blank (whitespace) characters, including spaces, tabs, new lines, carriage returns, form feeds, and vertical tabs |
+| `[:upper:]` | `[A-Z]` | uppercase letters |
+| `[:word:]` | `[A-Za-z0-9_]` | word characters |
+| `[:xdigit:]` | `[0-9A-Fa-f]` | hexadecimal digits |
+
+## Examples
+
+* `a[[:digit:]]b` matches `a0b`, `a1b`, ..., `a9b`.
+* `a[:digit:]b` is invalid, character classes must be enclosed in brackets
+* `[[:digit:]abc]` matches any digit, as well as `a`, `b`, and `c`.
+* `[abc[:digit:]]` is the same as the previous, matching any digit, as well as `a`, `b`, and `c`
+* `[^ABZ[:lower:]]` matches any character except lowercase letters, `A`, `B`, and `Z`.
+

+# pump
+
+pump is a small node module that pipes streams together and destroys all of them if one of them closes.
+
+```
+npm install pump
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/pump.svg?style=flat)](http://travis-ci.org/mafintosh/pump)
+
+## What problem does it solve?
+
+When using standard `source.pipe(dest)` source will _not_ be destroyed if dest emits close or an error.
+You are also not able to provide a callback to tell when then pipe has finished.
+
+pump does these two things for you
+
+## Usage
+
+Simply pass the streams you want to pipe together to pump and add an optional callback
+
+``` js
+var pump = require('pump')
+var fs = require('fs')
+
+var source = fs.createReadStream('/dev/random')
+var dest = fs.createWriteStream('/dev/null')
+
+pump(source, dest, function(err) {
+  console.log('pipe finished', err)
+})
+
+setTimeout(function() {
+  dest.destroy() // when dest is closed pump will destroy source
+}, 1000)
+```
+
+You can use pump to pipe more than two streams together as well
+
+``` js
+var transform = someTransformStream()
+
+pump(source, transform, anotherTransform, dest, function(err) {
+  console.log('pipe finished', err)
+})
+```
+
+If `source`, `transform`, `anotherTransform` or `dest` closes all of them will be destroyed.

+# pumpify
+
+Combine an array of streams into a single duplex stream using [pump](https://github.com/mafintosh/pump) and [duplexify](https://github.com/mafintosh/duplexify).
+If one of the streams closes/errors all streams in the pipeline will be destroyed.
+
+```
+npm install pumpify
+```
+
+[![build status](http://img.shields.io/travis/mafintosh/pumpify.svg?style=flat)](http://travis-ci.org/mafintosh/pumpify)
+
+## Usage
+
+Pass the streams you want to pipe together to pumpify `pipeline = pumpify(s1, s2, s3, ...)`.
+`pipeline` is a duplex stream that writes to the first streams and reads from the last one.
+Streams are piped together using [pump](https://github.com/mafintosh/pump) so if one of them closes
+all streams will be destroyed.
+
+``` js
+var pumpify = require('pumpify')
+var tar = require('tar-fs')
+var zlib = require('zlib')
+var fs = require('fs')
+
+var untar = pumpify(zlib.createGunzip(), tar.extract('output-folder'))
+// you can also pass an array instead
+// var untar = pumpify([zlib.createGunzip(), tar.extract('output-folder')])
+
+fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
+```
+
+If you are pumping object streams together use `pipeline = pumpify.obj(s1, s2, ...)`.
+Call `pipeline.destroy()` to destroy the pipeline (including the streams passed to pumpify).
+
+### Using `setPipeline(s1, s2, ...)`
+
+Similar to [duplexify](https://github.com/mafintosh/duplexify) you can also define the pipeline asynchronously using `setPipeline(s1, s2, ...)`
+
+``` js
+var untar = pumpify()
+
+setTimeout(function() {
+  // will start draining the input now
+  untar.setPipeline(zlib.createGunzip(), tar.extract('output-folder'))
+}, 1000)
+
+fs.createReadStream('some-gzipped-tarball.tgz').pipe(untar)
+```

+# read-pkg-up [![Build Status](https://travis-ci.org/sindresorhus/read-pkg-up.svg?branch=master)](https://travis-ci.org/sindresorhus/read-pkg-up)
+
+> Read the closest package.json file
+
+
+## Why
+
+- [Finds the closest package.json](https://github.com/sindresorhus/find-up)
+- [Gracefully handles filesystem issues](https://github.com/isaacs/node-graceful-fs)
+- [Strips UTF-8 BOM](https://github.com/sindresorhus/strip-bom)
+- [Throws more helpful JSON errors](https://github.com/sindresorhus/parse-json)
+- [Normalizes the data](https://github.com/npm/normalize-package-data#what-normalization-currently-entails)
+
+
+## Install
+
+```
+$ npm install --save read-pkg-up
+```
+
+
+## Usage
+
+```js
+var readPkgUp = require('read-pkg-up');
+
+readPkgUp().then(function (result) {
+	console.log(result);
+	/*
+	{
+		pkg: {
+			name: 'awesome-package',
+			version: '1.0.0',
+			...
+		},
+		path: '/Users/sindresorhus/dev/awesome-package'
+	}
+	*/
+});
+```
+
+
+## API
+
+### readPkgUp([options])
+
+Returns a promise that resolves to a result object.
+
+### readPkgUp.sync([options])
+
+Returns a result object.
+
+#### options
+
+##### cwd

+Type: `string`  
+Default: `.`
+
+Directory to start looking for a package.json file.
+
+##### normalize
+
+Type: `boolean`  
+Default: `true`

+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+Recursive version of [fs.readdir](http://nodejs.org/docs/latest/api/fs.html#fs_fs_readdir_path_callback). Exposes a **stream api**.
+
+```javascript
+var readdirp = require('readdirp')
+  , path = require('path')
+  , es = require('event-stream');
+
+// print out all JavaScript files along with their size
+
+var stream = readdirp({ root: path.join(__dirname), fileFilter: '*.js' });
+stream
+  .on('warn', function (err) {
+    console.error('non-fatal error', err);
+    // optionally call stream.destroy() here in order to abort and cause 'close' to be emitted
+  })
+  .on('error', function (err) { console.error('fatal error', err); })
+  .pipe(es.mapSync(function (entry) {
+    return { path: entry.path, size: entry.stat.size };
+  }))
+  .pipe(es.stringify())
+  .pipe(process.stdout);
+```
+
+Meant to be one of the recursive versions of [fs](http://nodejs.org/docs/latest/api/fs.html) functions, e.g., like [mkdirp](https://github.com/substack/node-mkdirp).

+# Installation
+
+    npm install readdirp
+
+# API
+
+***var entryStream = readdirp (options)***
+
+Reads given root recursively and returns a `stream` of [entry info](#entry-info)s.
+
+## entry stream
+
+Behaves as follows:
+
+- `emit('data')` passes an [entry info](#entry-info) whenever one is found
+- `emit('warn')` passes a non-fatal `Error` that prevents a file/directory from being processed (i.e., if it is
+  inaccessible to the user)
+- `emit('error')` passes a fatal `Error` which also ends the stream (i.e., when illegal options where passed)
+- `emit('end')` called when all entries were found and no more will be emitted (i.e., we are done)
+- `emit('close')` called when the stream is destroyed via `stream.destroy()` (which could be useful if you want to
+  manually abort even on a non fatal error) - at that point the stream is no longer `readable` and no more entries,
+  warning or errors are emitted
+- to learn more about streams, consult the very detailed
+  [nodejs streams documentation](http://nodejs.org/api/stream.html) or the
+  [stream-handbook](https://github.com/substack/stream-handbook)
+
+
+## options
+
+- **root**: path in which to start reading and recursing into subdirectories
+
+- **fileFilter**: filter to include/exclude files found (see [Filters](#filters) for more)
+
+- **directoryFilter**: filter to include/exclude directories found and to recurse into (see [Filters](#filters) for more)
+
+- **depth**: depth at which to stop recursing even if more subdirectories are found
+
+- **entryType**: determines if data events on the stream should be emitted for `'files'`, `'directories'`, `'both'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes. Defaults to `'files'`.
+
+- **lstat**: if `true`, readdirp uses `fs.lstat` instead of `fs.stat` in order to stat files and includes symlink entries in the stream along with files.
+
+## entry info
+
+Has the following properties:
+
+- **parentDir**     :  directory in which entry was found (relative to given root)
+- **fullParentDir** :  full path to parent directory
+- **name**          :  name of the file/directory
+- **path**          :  path to the file/directory (relative to given root)
+- **fullPath**      :  full path to the file/directory found
+- **stat**          :  built in [stat object](http://nodejs.org/docs/v0.4.9/api/fs.html#fs.Stats)
+- **Example**: (assuming root was `/User/dev/readdirp`)
+
+        parentDir     :  'test/bed/root_dir1',
+        fullParentDir :  '/User/dev/readdirp/test/bed/root_dir1',
+        name          :  'root_dir1_subdir1',
+        path          :  'test/bed/root_dir1/root_dir1_subdir1',
+        fullPath      :  '/User/dev/readdirp/test/bed/root_dir1/root_dir1_subdir1',
+        stat          :  [ ... ]
+
+## Filters
+
+There are three different ways to specify filters for files and directories respectively.
+
+- **function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
+
+- **glob string**: a string (e.g., `*.js`) which is matched using [minimatch](https://github.com/isaacs/minimatch), so go there for more
+    information.
+
+    Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense.
+
+    Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files.
+
+- **array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown.
+
+    `[ '*.json', '*.js' ]` includes all JavaScript and Json files.
+
+
+    `[ '!.git', '!node_modules' ]` includes all directories except the '.git' and 'node_modules'.
+
+Directories that do not pass a filter will not be recursed into.
+
+## Callback API
+
+Although the stream api is recommended, readdirp also exposes a callback based api.
+
+***readdirp (options, callback1 [, callback2])***
+
+If callback2 is given, callback1 functions as the **fileProcessed** callback, and callback2 as the **allProcessed** callback.
+
+If only callback1 is given, it functions as the **allProcessed** callback.
+
+### allProcessed
+
+- function with err and res parameters, e.g., `function (err, res) { ... }`
+- **err**: array of errors that occurred during the operation, **res may still be present, even if errors occurred**
+- **res**: collection of file/directory [entry infos](#entry-info)
+
+### fileProcessed
+
+- function with [entry info](#entry-info) parameter e.g., `function (entryInfo) { ... }`
+
+
+# More Examples
+
+`on('error', ..)`, `on('warn', ..)` and `on('end', ..)` handling omitted for brevity
+
+```javascript
+var readdirp = require('readdirp');
+
+// Glob file filter
+readdirp({ root: './test/bed', fileFilter: '*.js' })
+  .on('data', function (entry) {
+    // do something with each JavaScript file entry
+  });
+
+// Combined glob file filters
+readdirp({ root: './test/bed', fileFilter: [ '*.js', '*.json' ] })
+  .on('data', function (entry) {
+    // do something with each JavaScript and Json file entry
+  });
+
+// Combined negated directory filters
+readdirp({ root: './test/bed', directoryFilter: [ '!.git', '!*modules' ] })
+  .on('data', function (entry) {
+    // do something with each file entry found outside '.git' or any modules directory
+  });
+
+// Function directory filter
+readdirp({ root: './test/bed', directoryFilter: function (di) { return di.name.length === 9; } })
+  .on('data', function (entry) {
+    // do something with each file entry found inside directories whose name has length 9
+  });
+
+// Limiting depth
+readdirp({ root: './test/bed', depth: 1 })
+  .on('data', function (entry) {
+    // do something with each file entry found up to 1 subdirectory deep
+  });
+
+// callback api
+readdirp({ root: '.' }, function(fileInfo) {
+   // do something with file entry here
+  }, function (err, res) {
+    // all done, move on or do final step for all file entries here
+});
+```
+
+Try more examples by following [instructions](https://github.com/paulmillr/readdirp/blob/master/examples/Readme.md)
+on how to get going.
+
+## tests
+
+The [readdirp tests](https://github.com/paulmillr/readdirp/blob/master/test/readdirp.js) also will give you a good idea on
+how things work.

+# rechoir [![Build Status](https://secure.travis-ci.org/tkellen/js-rechoir.png)](http://travis-ci.org/tkellen/js-rechoir)
+> Require any supported file as a node module.
+
+[![NPM](https://nodei.co/npm/rechoir.png)](https://nodei.co/npm/rechoir/)
+
+## What is it?
+This module, in conjunction with [interpret]-like objects can register any file type the npm ecosystem has a module loader for. This library is a dependency of [Liftoff].
+
+## API
+
+### prepare(config, filepath, requireFrom)
+Look for a module loader associated with the provided file and attempt require it.  If necessary, run any setup required to inject it into [require.extensions](http://nodejs.org/api/globals.html#globals_require_extensions).
+
+`config` An [interpret]-like configuration object.  
+
+`filepath` A file whose type you'd like to register a module loader for.
+
+`requireFrom` An optional path to start searching for the module required to load the requested file.  Defaults to the directory of `filepath`.
+
+If calling this method is successful (aka: it doesn't throw), you can now require files of the type you requested natively.
+
+An error with a `failures` property will be thrown if the module loader(s) configured for a given extension cannot be registered.
+
+If a loader is already registered, this will simply return `true`.
+
+**Note:** While rechoir will automatically load and register transpilers like `coffee-script`, you must provide a local installation. The transpilers are **not** bundled with this module.
+
+#### Usage
+```js
+const config = require('interpret').extensions;
+const rechoir = require('rechoir');
+rechoir.prepare(config, './test/fixtures/test.coffee');
+rechoir.prepare(config, './test/fixtures/test.csv');
+rechoir.prepare(config, './test/fixtures/test.toml');
+
+console.log(require('./test/fixtures/test.coffee'));
+console.log(require('./test/fixtures/test.csv'));
+console.log(require('./test/fixtures/test.toml'));
+```

+> Create a javascript regular expression for matching everything except for the given string.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save regex-not
+```
+
+## Usage
+
+```js
+var not = require('regex-not');
+```
+
+The main export is a function that takes a string an options object.
+
+```js
+not(string[, options]);
+```
+
+**Example**
+
+```js
+var not = require('regex-not');
+console.log(not('foo'));
+//=> /^(?:(?!^(?:foo)$).)+$/
+```
+
+**Strict matching**
+
+By default, the returned regex is for strictly (not) matching the exact given pattern (in other words, "match this string if it does NOT _exactly equal_ `foo`"):
+
+```js
+var re = not('foo');
+console.log(re.test('foo'));     //=> false
+console.log(re.test('bar'));     //=> true
+console.log(re.test('foobar'));  //=> true
+console.log(re.test('barfoo'));  //=> true
+```

+Returns a string to allow you to create your own regex:
+
+```js
+console.log(not.create('foo'));
+//=> '(?:(?!^(?:foo)$).)+'
+```
+
+### Options
+
+**options.contains**
+
+You can relax strict matching by setting `options.contains` to true (in other words, "match this string if it does NOT _contain_ `foo`"):
+
+```js
+var re = not('foo');
+console.log(re.test('foo', {contains: true}));     //=> false
+console.log(re.test('bar', {contains: true}));     //=> true
+console.log(re.test('foobar', {contains: true}));  //=> false
+console.log(re.test('barfoo', {contains: true}));  //=> false
+```

+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable

+> Returns true if an object was created by the `Object` constructor.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-plain-object
+```
+
+Use [isobject](https://github.com/jonschlinkert/isobject) if you only want to check if the value is an object and not an array or null.
+
+## Usage
+
+```js
+var isPlainObject = require('is-plain-object');
+```
+
+**true** when created by the `Object` constructor.
+
+```js
+isPlainObject(Object.create({}));
+//=> true
+isPlainObject(Object.create(Object.prototype));
+//=> true
+isPlainObject({foo: 'bar'});
+//=> true
+isPlainObject({});
+//=> true
+```
+
+**false** when not created by the `Object` constructor.
+
+```js
+isPlainObject(1);
+//=> false
+isPlainObject(['foo', 'bar']);
+//=> false
+isPlainObject([]);
+//=> false
+isPlainObject(new Foo);
+//=> false
+isPlainObject(null);
+//=> false
+isPlainObject(Object.create(null));
+//=> false
+```

+
+Remove a UTF8 BOM at the start of the stream.
+
+## Usage
+
+```js
+var fs = require('fs');
+var concat = require('concat-stream');
+var removeBOM = require('remove-bom-stream');
+
+fs.createReadStream('utf8-file-with-bom.txt')
+  .pipe(removeBOM())
+  .pipe(concat(function(result) {
+    // result won't have a BOM
+  }));
+```
+
+## API
+
+### `removeBOM()`
+
+Returns a `through2` stream that will remove a BOM, given the data is a UTF8 Buffer with a BOM at the beginning. If the data is not UTF8 or does not have a BOM, the data is not changed and this becomes a normal passthrough stream.

+[![NPM version][npm-img]][npm-url] [![Build Status: Linux][travis-img]][travis-url] [![Build Status: Windows][appveyor-img]][appveyor-url] [![Coverage Status][coveralls-img]][coveralls-url]
+
+Removes all separators from the end of a string.
+
+## Install
+
+```
+npm install remove-trailing-separator
+```
+
+## Examples
+
+```js
+const removeTrailingSeparator = require('remove-trailing-separator');
+
+removeTrailingSeparator('/foo/bar/')   // '/foo/bar'
+removeTrailingSeparator('/foo/bar///') // '/foo/bar'
+
+// leaves only/last separator
+removeTrailingSeparator('/')    // '/'
+removeTrailingSeparator('///')  // '/'
+
+// returns empty string
+removeTrailingSeparator('') // ''
+```
+
+## Notable backslash, or win32 separator behavior
+
+`\` is considered a separator only on WIN32 systems. All POSIX compliant systems
+see backslash as a valid file name character, so it would break POSIX compliance
+to remove it there.
+
+In practice, this means that this code will return different things depending on
+what system it runs on:
+
+```js
+removeTrailingSeparator('\\foo\\')
+// UNIX  => '\\foo\\'
+// WIN32 => '\\foo'
+```

+
+> Repeat the given string n times. Fastest implementation for repeating a string.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save repeat-string
+```
+
+## Usage
+
+### [repeat](index.js#L41)
+
+Repeat the given `string` the specified `number` of times.
+
+**Example:**
+
+**Example**
+
+```js
+var repeat = require('repeat-string');
+repeat('A', 5);
+//=> AAAAA
+```
+
+**Params**
+
+* `string` **{String}**: The string to repeat
+* `number` **{Number}**: The number of times to repeat the string
+* `returns` **{String}**: Repeated string
+
+## Benchmarks
+
+Repeat string is significantly faster than the native method (which is itself faster than [repeating](https://github.com/sindresorhus/repeating)):
+
+```sh
+# 2x
+repeat-string  █████████████████████████  (26,953,977 ops/sec)
+repeating      █████████                  (9,855,695 ops/sec)
+native         ██████████████████         (19,453,895 ops/sec)

+[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][travis-image]][travis-url] [![AppVeyor Build Status][appveyor-image]][appveyor-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Gitter chat][gitter-image]][gitter-url]
+
+Replace user home in a string with another string. Useful for tildifying a path.
+
+## Usage
+
+```js
+var replaceHomedir = require('replace-homedir');
+
+var shortPath = replaceHomedir('/Users/phated/myProject', '~');
+// shortPath === '~/myProject'
+```
+
+## API
+
+### `replaceHomedir(path, replacement)`
+
+Takes a string `path` as the first argument and a string or function `replacement` as the second argument. If the `path` is absolute and begins with the User's homedir, the homedir portion of the path is replaced with `replacement` using String#replace.
+
+If `path` is not a string, the function will throw.

+# require-directory

+Recursively iterates over specified directory, `require()`'ing each file, and returning a nested hash structure containing those modules.
+
+**[Follow me (@troygoode) on Twitter!](https://twitter.com/intent/user?screen_name=troygoode)**
+
+[![NPM](https://nodei.co/npm/require-directory.png?downloads=true&stars=true)](https://nodei.co/npm/require-directory/)
+
+[![build status](https://secure.travis-ci.org/troygoode/node-require-directory.png)](http://travis-ci.org/troygoode/node-require-directory)
+
+## How To Use
+
+### Installation (via [npm](https://npmjs.org/package/require-directory))
+
+```bash
+$ npm install require-directory
+```
+
+### Usage
+
+A common pattern in node.js is to include an index file which creates a hash of the files in its current directory. Given a directory structure like so:
+
+* app.js
+* routes/
+  * index.js
+  * home.js
+  * auth/
+    * login.js
+    * logout.js
+    * register.js
+
+`routes/index.js` uses `require-directory` to build the hash (rather than doing so manually) like so:
+
+```javascript
+var requireDirectory = require('require-directory');
+module.exports = requireDirectory(module);
+```
+
+`app.js` references `routes/index.js` like any other module, but it now has a hash/tree of the exports from the `./routes/` directory:
+
+```javascript
+var routes = require('./routes');
+
+// snip
+
+app.get('/', routes.home);
+app.get('/register', routes.auth.register);
+app.get('/login', routes.auth.login);
+app.get('/logout', routes.auth.logout);
+```
+
+The `routes` variable above is the equivalent of this:
+
+```javascript
+var routes = {
+  home: require('routes/home.js'),
+  auth: {
+    login: require('routes/auth/login.js'),
+    logout: require('routes/auth/logout.js'),
+    register: require('routes/auth/register.js')
+  }
+};
+```
+
+*Note that `routes.index` will be `undefined` as you would hope.*
+
+### Specifying Another Directory
+
+You can specify which directory you want to build a tree of (if it isn't the current directory for whatever reason) by passing it as the second parameter. Not specifying the path (`requireDirectory(module)`) is the equivelant of `requireDirectory(module, __dirname)`:
+
+```javascript
+var requireDirectory = require('require-directory');
+module.exports = requireDirectory(module, './some/subdirectory');
+```
+
+For example, in the [example in the Usage section](#usage) we could have avoided creating `routes/index.js` and instead changed the first lines of `app.js` to:
+
+```javascript
+var requireDirectory = require('require-directory');
+var routes = requireDirectory(module, './routes');
+```
+
+## Options
+
+You can pass an options hash to `require-directory` as the 2nd parameter (or 3rd if you're passing the path to another directory as the 2nd parameter already). Here are the available options:
+
+### Whitelisting
+
+Whitelisting (either via RegExp or function) allows you to specify that only certain files be loaded.
+
+```javascript
+var requireDirectory = require('require-directory'),
+  whitelist = /onlyinclude.js$/,
+  hash = requireDirectory(module, {include: whitelist});
+```
+
+```javascript
+var requireDirectory = require('require-directory'),
+  check = function(path){
+    if(/onlyinclude.js$/.test(path)){
+      return true; // don't include
+    }else{
+      return false; // go ahead and include
+    }
+  },
+  hash = requireDirectory(module, {include: check});
+```
+
+### Blacklisting
+
+Blacklisting (either via RegExp or function) allows you to specify that all but certain files should be loaded.
+
+```javascript
+var requireDirectory = require('require-directory'),
+  blacklist = /dontinclude\.js$/,
+  hash = requireDirectory(module, {exclude: blacklist});
+```
+
+```javascript
+var requireDirectory = require('require-directory'),
+  check = function(path){
+    if(/dontinclude\.js$/.test(path)){
+      return false; // don't include
+    }else{
+      return true; // go ahead and include
+    }
+  },
+  hash = requireDirectory(module, {exclude: check});
+```
+
+### Visiting Objects As They're Loaded
+
+`require-directory` takes a function as the `visit` option that will be called for each module that is added to module.exports.
+
+```javascript
+var requireDirectory = require('require-directory'),
+  visitor = function(obj) {
+    console.log(obj); // will be called for every module that is loaded
+  },
+  hash = requireDirectory(module, {visit: visitor});
+```
+
+The visitor can also transform the objects by returning a value:
+
+```javascript
+var requireDirectory = require('require-directory'),
+  visitor = function(obj) {
+    return obj(new Date());
+  },
+  hash = requireDirectory(module, {visit: visitor});
+```
+
+### Renaming Keys
+
+```javascript
+var requireDirectory = require('require-directory'),
+  renamer = function(name) {
+    return name.toUpperCase();
+  },
+  hash = requireDirectory(module, {rename: renamer});
+```
+
+### No Recursion
+
+```javascript
+var requireDirectory = require('require-directory'),
+  hash = requireDirectory(module, {recurse: false});
+```
+
+## Run Unit Tests
+
+```bash
+$ npm run lint
+$ npm test
+```

+[![NPM version](https://img.shields.io/npm/v/require-main-filename.svg)](https://www.npmjs.com/package/require-main-filename)
+
+`require.main.filename` is great for figuring out the entry
+point for the current application. This can be combined with a module like
+[pkg-conf](https://www.npmjs.com/package/pkg-conf) to, _as if by magic_, load
+top-level configuration.
+
+Unfortunately, `require.main.filename` sometimes fails when an application is
+executed with an alternative process manager, e.g., [iisnode](https://github.com/tjanczuk/iisnode).
+
+`require-main-filename` is a shim that addresses this problem.
+
+## Usage
+
+```js
+var main = require('require-main-filename')()
+// use main as an alternative to require.main.filename.
+```

+
+Resolve an options object based on configuration.
+
+## Usage
+
+```js
+// This example assumes a Vinyl file
+
+var createResolver = require('resolve-options');
+
+var config = {
+  cwd: {
+    type: 'string',
+    default: process.cwd
+  },
+  sourcemaps: {
+    type: 'boolean',
+    default: false
+  },
+  since: {
+    type: ['date', 'number']
+  },
+  read: {
+    type: 'boolean'
+  }
+};
+
+var options = {
+  sourcemaps: true,
+  since: Date.now(),
+  read: function(file) {
+    return (file.extname !== '.mp4');
+  }
+};
+
+var resolver = createResolver(config, options);
+
+var cwd = resolver.resolve('cwd', file);
+// cwd === process.cwd()
+
+var sourcemaps = resolver.resolve('sourcemaps', file);
+// sourcemaps === true
+
+var read = resolver.resolve('read', file);
+// Given .mp4, read === false
+// Given .txt, read === true
+```
+
+## API
+
+### `createResolver([config,] [options])`
+
+Takes a `config` object that describes the options to accept/resolve and an `options` object (usually passed by a user) to resolve against the `config`. Returns a `resolver` that contains a `resolve` method for realtime resolution of options.
+
+The `config` object takes the following structure:
+```graphql
+config {
+  [optionKey] {
+    type // string, array or function
+    default // any value or function
+  }
+}
+```
+
+Each option is represented by its `optionKey` in the `config` object. It must be an object with a `type` property.
+
+The `type` property must be a string, array or function which will be passed to the [`value-or-function`][value-or-function] module (functions will be bound to the resolver to allow for dependent options).
+
+A `default` property may also be specified as a fallback if the option isn't available or is invalid. The `default` value can be any value or a function (functions will be bound to the resolver to allow for dependent defaults). __Note:__ `default` values are not type-validated by the `value-or-function` module.
+
+### `resolver.resolve(optionKey, [...arguments])`
+
+Takes an `optionKey` string and any number of `arguments` to apply if an option is a function. Returns the resolved value for the `optionKey`.

+[![browser support](https://ci.testling.com/lydell/resolve-url.png)](https://ci.testling.com/lydell/resolve-url)
+
+Like Node.js’ [`path.resolve`]/[`url.resolve`] for the browser.
+
+```js
+var resolveUrl = require("resolve-url")
+
+window.location
+// https://example.com/articles/resolving-urls/edit
+
+resolveUrl("remove")
+// https://example.com/articles/resolving-urls/remove
+
+resolveUrl("/static/scripts/app.js")
+// https://example.com/static/scripts/app.js
+
+// Imagine /static/scripts/app.js contains `//# sourceMappingURL=../source-maps/app.js.map`
+resolveUrl("/static/scripts/app.js", "../source-maps/app.js.map")
+// https://example.com/static/source-maps/app.js.map
+
+resolveUrl("/static/scripts/app.js", "../source-maps/app.js.map", "../coffee/app.coffee")
+// https://example.com/static/coffee/app.coffee
+
+resolveUrl("//cdn.example.com/jquery.js")
+// https://cdn.example.com/jquery.js
+
+resolveUrl("http://foo.org/")
+// http://foo.org/
+```
+
+
+Installation
+============
+
+- `npm install resolve-url`
+- `bower install resolve-url`
+- `component install lydell/resolve-url`
+
+Works with CommonJS, AMD and browser globals, through UMD.
+
+
+Usage
+=====
+
+### `resolveUrl(...urls)` ###
+
+Pass one or more urls. Resolves the last one to an absolute url, using the
+previous ones and `window.location`.
+
+It’s like starting out on `window.location`, and then clicking links with the
+urls as `href` attributes in order, from left to right.
+
+Unlike Node.js’ [`path.resolve`], this function always goes through all of the
+arguments, from left to right. `path.resolve` goes from right to left and only
+in the worst case goes through them all. Should that matter.
+
+Actually, the function is _really_ like clicking a lot of links in series: An
+actual `` gets its `href` attribute set for each url! This means that the
+url resolution of the browser is used, which makes this module really
+light-weight.
+
+Also note that this functions deals with urls, not paths, so in that respect it
+has more in common with Node.js’ [`url.resolve`]. But the arguments are more
+like [`path.resolve`].
+
+[`path.resolve`]: http://nodejs.org/api/path.html#path_path_resolve_from_to
+[`url.resolve`]: http://nodejs.org/api/url.html#url_url_resolve_from_to
+
+
+Tests
+=====
+
+Run `npm test`, which lints the code and then gives you a link to open in a
+browser of choice (using `testling`).

+# resolve [![Version Badge][2]][1]
+
+implements the [node `require.resolve()` algorithm](https://nodejs.org/api/modules.html#modules_all_together) such that you can `require.resolve()` on behalf of a file asynchronously and synchronously

+# example
+
+asynchronously resolve:
+
+```js
+var resolve = require('resolve/async'); // or, require('resolve')
+resolve('tap', { basedir: __dirname }, function (err, res) {
+    if (err) console.error(err);
+    else console.log(res);
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+```js
+var resolve = require('resolve/sync'); // or, `require('resolve').sync
+var res = resolve('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+```js
+var resolve = require('resolve');
+var async = require('resolve/async');
+var sync = require('resolve/sync');
+```
+
+For both the synchronous and asynchronous methods, errors may have any of the following `err.code` values:
+
+- `MODULE_NOT_FOUND`: the given path string (`id`) could not be resolved to a module
+- `INVALID_BASEDIR`: the specified `opts.basedir` doesn't exist, or is not a directory
+- `INVALID_PACKAGE_MAIN`: a `package.json` was encountered with an invalid `main` property (eg. not a string)
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.includeCoreModules - set to `false` to exclude node core modules (e.g. `fs`) from the search
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* opts.isDirectory - function to asynchronously test whether a file exists and is a directory
+
+* opts.realpath - function to asynchronously resolve a potential symlink to its real path
+
+* `opts.readPackage(readFile, pkgfile, cb)` - function to asynchronously read and parse a package.json file
+  * readFile - the passed `opts.readFile` or `fs.readFile` if not specified
+  * pkgfile - path to package.json
+  * cb - callback
+
+* `opts.packageFilter(pkg, pkgfile, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * pkgfile - path to package.json
+  * dir - directory that contains package.json
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* `opts.packageIterator(request, start, opts)` - return the list of candidate paths where the packages sources may be found (probably don't use this)

+## resolve.sync(id, opts)
+
+Synchronously resolve the module path string `id`, returning the result and
+throwing an error when `id` can't be resolved.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.includeCoreModules - set to `false` to exclude node core modules (e.g. `fs`) from the search
+
+* opts.readFileSync - how to read files synchronously
+
+* opts.isFile - function to synchronously test whether a file exists
+
+* opts.isDirectory - function to synchronously test whether a file exists and is a directory
+
+* opts.realpathSync - function to synchronously resolve a potential symlink to its real path
+
+* `opts.readPackageSync(readFileSync, pkgfile)` - function to synchronously read and parse a package.json file
+  * readFileSync - the passed `opts.readFileSync` or `fs.readFileSync` if not specified
+  * pkgfile - path to package.json
+
+* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * dir - directory that contains package.json (Note: the second argument will change to "pkgfile" in v2)
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* `opts.packageIterator(request, start, opts)` - return the list of candidate paths where the packages sources may be found (probably don't use this)
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getPackageCandidates - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.

+# Regular Expression Tokenizer
+
+Tokenizes strings that represent a regular expressions.
+
+[![Build Status](https://secure.travis-ci.org/fent/ret.js.svg)](http://travis-ci.org/fent/ret.js)
+[![Dependency Status](https://david-dm.org/fent/ret.js.svg)](https://david-dm.org/fent/ret.js)
+[![codecov](https://codecov.io/gh/fent/ret.js/branch/master/graph/badge.svg)](https://codecov.io/gh/fent/ret.js)
+
+# Usage
+
+```js
+var ret = require('ret');
+
+var tokens = ret(/foo|bar/.source);
+```
+
+`tokens` will contain the following object
+
+```js
+{
+  "type": ret.types.ROOT
+  "options": [
+    [ { "type": ret.types.CHAR, "value", 102 },
+      { "type": ret.types.CHAR, "value", 111 },
+      { "type": ret.types.CHAR, "value", 111 } ],
+    [ { "type": ret.types.CHAR, "value",  98 },
+      { "type": ret.types.CHAR, "value",  97 },
+      { "type": ret.types.CHAR, "value", 114 } ]
+  ]
+}
+```
+
+# Token Types
+
+`ret.types` is a collection of the various token types exported by ret.
+
+### ROOT
+
+Only used in the root of the regexp. This is needed due to the posibility of the root containing a pipe `|` character. In that case, the token will have an `options` key that will be an array of arrays of tokens. If not, it will contain a `stack` key that is an array of tokens.
+
+```js
+{
+  "type": ret.types.ROOT,
+  "stack": [token1, token2...],
+}
+```
+
+```js
+{
+  "type": ret.types.ROOT,
+  "options" [
+    [token1, token2...],
+    [othertoken1, othertoken2...]
+    ...
+  ],
+}
+```
+
+### GROUP
+
+Groups contain tokens that are inside of a parenthesis. If the group begins with `?` followed by another character, it's a special type of group. A ':' tells the group not to be remembered when `exec` is used. '=' means the previous token matches only if followed by this group, and '!' means the previous token matches only if NOT followed.
+
+Like root, it can contain an `options` key instead of `stack` if there is a pipe.
+
+```js
+{
+  "type": ret.types.GROUP,
+  "remember" true,
+  "followedBy": false,
+  "notFollowedBy": false,
+  "stack": [token1, token2...],
+}
+```
+
+```js
+{
+  "type": ret.types.GROUP,
+  "remember" true,
+  "followedBy": false,
+  "notFollowedBy": false,
+  "options" [
+    [token1, token2...],
+    [othertoken1, othertoken2...]
+    ...
+  ],
+}
+```
+
+### POSITION
+
+`\b`, `\B`, `^`, and `$` specify positions in the regexp.
+
+```js
+{
+  "type": ret.types.POSITION,
+  "value": "^",
+}
+```
+
+### SET
+
+Contains a key `set` specifying what tokens are allowed and a key `not` specifying if the set should be negated. A set can contain other sets, ranges, and characters.
+
+```js
+{
+  "type": ret.types.SET,
+  "set": [token1, token2...],
+  "not": false,
+}
+```
+
+### RANGE
+
+Used in set tokens to specify a character range. `from` and `to` are character codes.
+
+```js
+{
+  "type": ret.types.RANGE,
+  "from": 97,
+  "to": 122,
+}
+```
+
+### REPETITION
+
+```js
+{
+  "type": ret.types.REPETITION,
+  "min": 0,
+  "max": Infinity,
+  "value": token,
+}
+```
+
+### REFERENCE
+
+References a group token. `value` is 1-9.
+
+```js
+{
+  "type": ret.types.REFERENCE,
+  "value": 1,
+}
+```
+
+### CHAR
+
+Represents a single character token. `value` is the character code. This might seem a bit cluttering instead of concatenating characters together. But since repetition tokens only repeat the last token and not the last clause like the pipe, it's simpler to do it this way.
+
+```js
+{
+  "type": ret.types.CHAR,
+  "value": 123,
+}
+```
+
+## Errors
+
+ret.js will throw errors if given a string with an invalid regular expression. All possible errors are
+
+* Invalid group. When a group with an immediate `?` character is followed by an invalid character. It can only be followed by `!`, `=`, or `:`. Example: `/(?_abc)/`
+* Nothing to repeat. Thrown when a repetitional token is used as the first token in the current clause, as in right in the beginning of the regexp or group, or right after a pipe. Example: `/foo|?bar/`, `/{1,3}foo|bar/`, `/foo(+bar)/`
+* Unmatched ). A group was not opened, but was closed. Example: `/hello)2u/`
+* Unterminated group. A group was not closed. Example: `/(1(23)4/`
+* Unterminated character class. A custom character set was not closed. Example: `/[abc/`

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: 
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: 
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // 
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // 
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // 
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // 
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // 
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).

+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+# example
+
+``` js
+var safe = require('safe-regex');
+var regex = process.argv.slice(2).join(' ');
+console.log(safe(regex));
+```
+
+```
+$ node safe.js '(x+x+)+y'

+true
+$ node safe.js '(a+){10}'
+false
+$ node safe.js '\blocation\s*:[^:\n]+\b(Oakland|San Francisco)\b'

+```
+
+# methods
+
+``` js
+var safe = require('safe-regex')
+```
+
+## var ok = safe(re, opts={})
+
+Return a boolean `ok` whether or not the regex `re` is safe and not possibly
+catastrophic.
+
+`re` can be a `RegExp` object or just a string.
+
+If the `re` is a string and is an invalid regex, returns `false`.
+
+* `opts.limit` - maximum number of allowed repetitions in the entire regex.
+Default: `25`.

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+A pure JavaScript implementation of [Sass][sass]. **Sass makes CSS fun again**.

+
+[sass]: https://sass-lang.com/
+
+This package is a distribution of [Dart Sass][], compiled to pure JavaScript
+with no native code or external dependencies. It provides a command-line `sass`
+executable and a Node.js API.
+
+[Dart Sass]: https://github.com/sass/dart-sass
+
+* [Usage](#usage)
+* [See Also](#see-also)
+* [Behavioral Differences from Ruby Sass](#behavioral-differences-from-ruby-sass)
+
+## Usage
+
+You can install Sass globally using `npm install -g sass` which will provide
+access to the `sass` executable. You can also add it to your project using
+`npm install --save-dev sass`. This provides the executable as well as a
+library:
+
+[npm]: https://www.npmjs.com/package/sass
+
+```js
+const sass = require('sass');
+
+const result = sass.compile(scssFilename);
+
+// OR
+
+// Note that `compileAsync()` is substantially slower than `compile()`.
+const result = await sass.compileAsync(scssFilename);
+```
+
+See [the Sass website][js api] for full API documentation.
+
+[js api]: https://sass-lang.com/documentation/js-api
+
+### Legacy API
+
+Dart Sass also supports an older JavaScript API that's fully compatible with
+[Node Sass] (with a few exceptions listed below), with support for both the
+[`render()`] and [`renderSync()`] functions. This API is considered deprecated
+and will be removed in Dart Sass 2.0.0, so it should be avoided in new projects.
+
+[Node Sass]: https://github.com/sass/node-sass
+[`render()`]: https://sass-lang.com/documentation/js-api/modules#render
+[`renderSync()`]: https://sass-lang.com/documentation/js-api/modules#renderSync
+
+Sass's support for the legacy JavaScript API has the following limitations:
+
+* Only the `"expanded"` and `"compressed"` values of [`outputStyle`] are
+  supported.
+
+* Dart Sass doesn't support the [`precision`] option. Dart Sass defaults to a
+  sufficiently high precision for all existing browsers, and making this
+  customizable would make the code substantially less efficient.
+
+* Dart Sass doesn't support the [`sourceComments`] option. Source maps are the
+  recommended way of locating the origin of generated selectors.
+
+[`outputStyle`]: https://sass-lang.com/documentation/js-api/interfaces/LegacySharedOptions#outputStyle
+[`precision`]: https://github.com/sass/node-sass#precision
+[`sourceComments`]: https://github.com/sass/node-sass#sourcecomments
+
+## See Also
+
+* [Dart Sass][], from which this package is compiled, can be used either as a
+  stand-alone executable or as a Dart library. Running Dart Sass on the Dart VM
+  is substantially faster than running the pure JavaScript version, so this may
+  be appropriate for performance-sensitive applications. The Dart API is also
+  (currently) more user-friendly than the JavaScript API. See
+  [the Dart Sass README][Using Dart Sass] for details on how to use it.
+
+* [Node Sass][], which is a wrapper around [LibSass][], the C++ implementation
+  of Sass. Node Sass supports the same API as this package and is also faster
+  (although it's usually a little slower than Dart Sass). However, it requires a
+  native library which may be difficult to install, and it's generally slower to
+  add features and fix bugs.
+

+[Node Sass]: https://www.npmjs.com/package/node-sass
+[LibSass]: https://sass-lang.com/libsass
+
+## Behavioral Differences from Ruby Sass
+
+There are a few intentional behavioral differences between Dart Sass and Ruby
+Sass. These are generally places where Ruby Sass has an undesired behavior, and
+it's substantially easier to implement the correct behavior than it would be to
+implement compatible behavior. These should all have tracking bugs against Ruby
+Sass to update the reference behavior.
+
+1. `@extend` only accepts simple selectors, as does the second argument of
+   `selector-extend()`. See [issue 1599][].
+
+2. Subject selectors are not supported. See [issue 1126][].
+
+3. Pseudo selector arguments are parsed as ``s rather than
+   having a more limited custom parsing. See [issue 2120][].
+
+4. The numeric precision is set to 10. See [issue 1122][].
+
+5. The indented syntax parser is more flexible: it doesn't require consistent
+   indentation across the whole document. See [issue 2176][].
+
+6. Colors do not support channel-by-channel arithmetic. See [issue 2144][].
+
+7. Unitless numbers aren't `==` to unit numbers with the same value. In
+   addition, map keys follow the same logic as `==`-equality. See
+   [issue 1496][].
+
+8. `rgba()` and `hsla()` alpha values with percentage units are interpreted as
+   percentages. Other units are forbidden. See [issue 1525][].
+
+9. Too many variable arguments passed to a function is an error. See
+   [issue 1408][].
+
+10. Allow `@extend` to reach outside a media query if there's an identical
+    `@extend` defined outside that query. This isn't tracked explicitly, because
+    it'll be irrelevant when [issue 1050][] is fixed.
+
+11. Some selector pseudos containing placeholder selectors will be compiled
+    where they wouldn't be in Ruby Sass. This better matches the semantics of
+    the selectors in question, and is more efficient. See [issue 2228][].
+
+12. The old-style `:property value` syntax is not supported in the indented
+    syntax. See [issue 2245][].
+
+13. The reference combinator is not supported. See [issue 303][].
+
+14. Universal selector unification is symmetrical. See [issue 2247][].
+
+15. `@extend` doesn't produce an error if it matches but fails to unify. See
+    [issue 2250][].
+
+16. Dart Sass currently only supports UTF-8 documents. We'd like to support
+    more, but Dart currently doesn't support them. See [dart-lang/sdk#11744][],
+    for example.

+======
+Javascript module to match a string against a regular expression, glob, string,
+or function that takes the string as an argument and returns a truthy or falsy
+value. The matcher can also be an array of any or all of these. Useful for
+allowing a very flexible user-defined config to define things like file paths.
+
+__Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See https://github.com/micromatch/micromatch#backslashes for more information.__
+
+
+Usage
+-----
+```sh
+npm install anymatch
+```
+
+#### anymatch(matchers, testString, [returnIndex], [options])
+* __matchers__: (_Array|String|RegExp|Function_)
+String to be directly matched, string with glob patterns, regular expression
+test, function that takes the testString as an argument and returns a truthy
+value if it should be matched, or an array of any number and mix of these types.
+* __testString__: (_String|Array_) The string to test against the matchers. If
+passed as an array, the first element of the array will be used as the
+`testString` for non-function matchers, while the entire array will be applied
+as the arguments for function matchers.
+* __options__: (_Object_ [optional]_) Any of the [picomatch](https://github.com/micromatch/picomatch#options) options.
+    * __returnIndex__: (_Boolean [optional]_) If true, return the array index of
+the first matcher that that testString matched, or -1 if no match, instead of a
+boolean result.
+
+```js
+const anymatch = require('anymatch');
+
+const matchers = [ 'path/to/file.js', 'path/anyjs/**/*.js', /foo.js$/, string => string.includes('bar') && string.length > 10 ] ;
+
+anymatch(matchers, 'path/to/file.js'); // true
+anymatch(matchers, 'path/anyjs/baz.js'); // true
+anymatch(matchers, 'path/to/foo.js'); // true
+anymatch(matchers, 'path/to/bar.js'); // true
+anymatch(matchers, 'bar.js'); // false
+
+// returnIndex = true
+anymatch(matchers, 'foo.js', {returnIndex: true}); // 2
+anymatch(matchers, 'path/anyjs/foo.js', {returnIndex: true}); // 1
+
+// any picomatc
+
+// using globs to match directories and their children
+anymatch('node_modules', 'node_modules'); // true
+anymatch('node_modules', 'node_modules/somelib/index.js'); // false
+anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
+anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
+anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
+
+const matcher = anymatch(matchers);
+['foo.js', 'bar.js'].filter(matcher);  // [ 'foo.js' ]
+anymatch master* ❯
+
+```
+
+#### anymatch(matchers)
+You can also pass in only your matcher(s) to get a curried function that has
+already been bound to the provided matching criteria. This can be used as an
+`Array#filter` callback.
+
+```js
+var matcher = anymatch(matchers);
+
+matcher('path/to/file.js'); // true
+matcher('path/anyjs/baz.js', true); // 1
+
+['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
+```
+
+Changelog
+----------
+[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
+
+- **v3.0:** Removed `startIndex` and `endIndex` arguments. Node 8.x-only.
+- **v2.0:** [micromatch](https://github.com/jonschlinkert/micromatch) moves away from minimatch-parity and inline with Bash. This includes handling backslashes differently (see https://github.com/micromatch/micromatch#backslashes for more information).
+- **v1.2:** anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
+for glob pattern matching. Issues with glob pattern matching should be
+reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

+
+> Bash-like brace expansion, implemented in JavaScript. Safer than other brace expansion libs, with complete support for the Bash 4.3 braces specification, without sacrificing speed.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save braces
+```
+
+## v3.0.0 Released!!
+
+See the [changelog](CHANGELOG.md) for details.
+
+## Why use braces?
+
+Brace patterns make globs more powerful by adding the ability to match specific ranges and sequences of characters.
+
+* **Accurate** - complete support for the [Bash 4.3 Brace Expansion](www.gnu.org/software/bash/) specification (passes all of the Bash braces tests)
+* **[fast and performant](#benchmarks)** - Starts fast, runs fast and [scales well](#performance) as patterns increase in complexity.
+* **Organized code base** - The parser and compiler are easy to maintain and update when edge cases crop up.
+* **Well-tested** - Thousands of test assertions, and passes all of the Bash, minimatch, and [brace-expansion](https://github.com/juliangruber/brace-expansion) unit tests (as of the date this was written).
+* **Safer** - You shouldn't have to worry about users defining aggressive or malicious brace patterns that can break your application. Braces takes measures to prevent malicious regex that can be used for DDoS attacks (see [catastrophic backtracking](https://www.regular-expressions.info/catastrophic.html)).
+* [Supports lists](#lists) - (aka "sets") `a/{b,c}/d` => `['a/b/d', 'a/c/d']`
+* [Supports sequences](#sequences) - (aka "ranges") `{01..03}` => `['01', '02', '03']`
+* [Supports steps](#steps) - (aka "increments") `{2..10..2}` => `['2', '4', '6', '8', '10']`
+* [Supports escaping](#escaping) - To prevent evaluation of special characters.
+
+## Usage
+
+The main export is a function that takes one or more brace `patterns` and `options`.
+
+```js
+const braces = require('braces');
+// braces(patterns[, options]);
+
+console.log(braces(['{01..05}', '{a..e}']));
+//=> ['(0[1-5])', '([a-e])']
+
+console.log(braces(['{01..05}', '{a..e}'], { expand: true }));
+//=> ['01', '02', '03', '04', '05', 'a', 'b', 'c', 'd', 'e']
+```
+
+### Brace Expansion vs. Compilation
+
+By default, brace patterns are compiled into strings that are optimized for creating regular expressions and matching.
+
+**Compiled**
+
+```js
+console.log(braces('a/{x,y,z}/b')); 
+//=> ['a/(x|y|z)/b']
+console.log(braces(['a/{01..20}/b', 'a/{1..5}/b'])); 
+//=> [ 'a/(0[1-9]|1[0-9]|20)/b', 'a/([1-5])/b' ]
+```
+
+**Expanded**
+
+Enable brace expansion by setting the `expand` option to true, or by using [braces.expand()](#expand) (returns an array similar to what you'd expect from Bash, or `echo {1..5}`, or [minimatch](https://github.com/isaacs/minimatch)):
+
+```js
+console.log(braces('a/{x,y,z}/b', { expand: true }));
+//=> ['a/x/b', 'a/y/b', 'a/z/b']
+
+console.log(braces.expand('{01..10}'));
+//=> ['01','02','03','04','05','06','07','08','09','10']
+```
+
+### Lists
+
+Expand lists (like Bash "sets"):
+
+```js
+console.log(braces('a/{foo,bar,baz}/*.js'));
+//=> ['a/(foo|bar|baz)/*.js']
+
+console.log(braces.expand('a/{foo,bar,baz}/*.js'));
+//=> ['a/foo/*.js', 'a/bar/*.js', 'a/baz/*.js']
+```
+
+### Sequences
+
+Expand ranges of characters (like Bash "sequences"):
+
+```js
+console.log(braces.expand('{1..3}'));                // ['1', '2', '3']
+console.log(braces.expand('a/{1..3}/b'));            // ['a/1/b', 'a/2/b', 'a/3/b']
+console.log(braces('{a..c}', { expand: true }));     // ['a', 'b', 'c']
+console.log(braces('foo/{a..c}', { expand: true })); // ['foo/a', 'foo/b', 'foo/c']
+
+// supports zero-padded ranges
+console.log(braces('a/{01..03}/b'));   //=> ['a/(0[1-3])/b']
+console.log(braces('a/{001..300}/b')); //=> ['a/(0{2}[1-9]|0[1-9][0-9]|[12][0-9]{2}|300)/b']
+```
+
+See [fill-range](https://github.com/jonschlinkert/fill-range) for all available range-expansion options.
+
+### Steppped ranges
+
+Steps, or increments, may be used with ranges:
+
+```js
+console.log(braces.expand('{2..10..2}'));
+//=> ['2', '4', '6', '8', '10']
+
+console.log(braces('{2..10..2}'));
+//=> ['(2|4|6|8|10)']
+```
+
+When the [.optimize](#optimize) method is used, or [options.optimize](#optionsoptimize) is set to true, sequences are passed to [to-regex-range](https://github.com/jonschlinkert/to-regex-range) for expansion.
+
+### Nesting
+
+Brace patterns may be nested. The results of each expanded string are not sorted, and left to right order is preserved.
+
+**"Expanded" braces**
+
+```js
+console.log(braces.expand('a{b,c,/{x,y}}/e'));
+//=> ['ab/e', 'ac/e', 'a/x/e', 'a/y/e']
+
+console.log(braces.expand('a/{x,{1..5},y}/c'));
+//=> ['a/x/c', 'a/1/c', 'a/2/c', 'a/3/c', 'a/4/c', 'a/5/c', 'a/y/c']
+```
+
+**"Optimized" braces**
+
+```js
+console.log(braces('a{b,c,/{x,y}}/e'));
+//=> ['a(b|c|/(x|y))/e']
+
+console.log(braces('a/{x,{1..5},y}/c'));
+//=> ['a/(x|([1-5])|y)/c']
+```
+
+### Escaping
+
+**Escaping braces**
+
+A brace pattern will not be expanded or evaluted if _either the opening or closing brace is escaped_:
+
+```js
+console.log(braces.expand('a\\{d,c,b}e'));
+//=> ['a{d,c,b}e']
+
+console.log(braces.expand('a{d,c,b\\}e'));
+//=> ['a{d,c,b}e']
+```
+
+**Escaping commas**
+
+Commas inside braces may also be escaped:
+
+```js
+console.log(braces.expand('a{b\\,c}d'));
+//=> ['a{b,c}d']
+
+console.log(braces.expand('a{d\\,c,b}e'));
+//=> ['ad,ce', 'abe']
+```
+
+**Single items**
+
+Following bash conventions, a brace pattern is also not expanded when it contains a single character:
+
+```js
+console.log(braces.expand('a{b}c'));
+//=> ['a{b}c']
+```
+
+## Options
+
+### options.maxLength
+
+**Type**: `Number`
+
+**Default**: `65,536`
+
+**Description**: Limit the length of the input string. Useful when the input string is generated or your application allows users to pass a string, et cetera.
+
+```js
+console.log(braces('a/{b,c}/d', { maxLength: 3 }));  //=> throws an error
+```
+
+### options.expand
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Generate an "expanded" brace pattern (alternatively you can use the `braces.expand()` method, which does the same thing).
+
+```js
+console.log(braces('a/{b,c}/d', { expand: true }));
+//=> [ 'a/b/d', 'a/c/d' ]
+```
+
+### options.nodupes
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Remove duplicates from the returned array.
+
+### options.rangeLimit
+
+**Type**: `Number`
+
+**Default**: `1000`
+
+**Description**: To prevent malicious patterns from being passed by users, an error is thrown when `braces.expand()` is used or `options.expand` is true and the generated range will exceed the `rangeLimit`.
+
+You can customize `options.rangeLimit` or set it to `Inifinity` to disable this altogether.
+
+**Examples**
+
+```js
+// pattern exceeds the "rangeLimit", so it's optimized automatically
+console.log(braces.expand('{1..1000}'));
+//=> ['([1-9]|[1-9][0-9]{1,2}|1000)']
+
+// pattern does not exceed "rangeLimit", so it's NOT optimized
+console.log(braces.expand('{1..100}'));
+//=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62', '63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74', '75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86', '87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', '98', '99', '100']
+```
+
+### options.transform
+
+**Type**: `Function`
+
+**Default**: `undefined`
+
+**Description**: Customize range expansion.
+
+**Example: Transforming non-numeric values**
+
+```js
+const alpha = braces.expand('x/{a..e}/y', {
+  transform(value, index) {
+    // When non-numeric values are passed, "value" is a character code.
+    return 'foo/' + String.fromCharCode(value) + '-' + index;
+  }
+});
+console.log(alpha);
+//=> [ 'x/foo/a-0/y', 'x/foo/b-1/y', 'x/foo/c-2/y', 'x/foo/d-3/y', 'x/foo/e-4/y' ]
+```
+
+**Example: Transforming numeric values**
+
+```js
+const numeric = braces.expand('{1..5}', {
+  transform(value) {
+    // when numeric values are passed, "value" is a number
+    return 'foo/' + value * 2;
+  }
+});
+console.log(numeric); 
+//=> [ 'foo/2', 'foo/4', 'foo/6', 'foo/8', 'foo/10' ]
+```
+
+### options.quantifiers
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: In regular expressions, quanitifiers can be used to specify how many times a token can be repeated. For example, `a{1,3}` will match the letter `a` one to three times.
+
+Unfortunately, regex quantifiers happen to share the same syntax as [Bash lists](#lists)
+
+The `quantifiers` option tells braces to detect when [regex quantifiers](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp#quantifiers) are defined in the given pattern, and not to try to expand them as lists.
+
+**Examples**
+
+```js
+const braces = require('braces');
+console.log(braces('a/b{1,3}/{x,y,z}'));
+//=> [ 'a/b(1|3)/(x|y|z)' ]
+console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true}));
+//=> [ 'a/b{1,3}/(x|y|z)' ]
+console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true, expand: true}));
+//=> [ 'a/b{1,3}/x', 'a/b{1,3}/y', 'a/b{1,3}/z' ]
+```
+
+### options.unescape
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Strip backslashes that were used for escaping from the result.
+
+## What is "brace expansion"?
+
+Brace expansion is a type of parameter expansion that was made popular by unix shells for generating lists of strings, as well as regex-like matching when used alongside wildcards (globs).
+
+In addition to "expansion", braces are also used for matching. In other words:
+
+* [brace expansion](#brace-expansion) is for generating new lists
+* [brace matching](#brace-matching) is for filtering existing lists
+
+

+More about brace expansion (click to expand)
+
+There are two main types of brace expansion:
+
+1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}`
+2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges".
+
+Here are some example brace patterns to illustrate how they work:
+
+**Sets**
+
+```
+{a,b,c}       => a b c
+{a,b,c}{1,2}  => a1 a2 b1 b2 c1 c2
+```
+
+**Sequences**
+
+```
+{1..9}        => 1 2 3 4 5 6 7 8 9
+{4..-4}       => 4 3 2 1 0 -1 -2 -3 -4
+{1..20..3}    => 1 4 7 10 13 16 19
+{a..j}        => a b c d e f g h i j
+{j..a}        => j i h g f e d c b a
+{a..z..3}     => a d g j m p s v y
+```
+
+**Combination**
+
+Sets and sequences can be mixed together or used along with any other strings.
+
+```
+{a,b,c}{1..3}   => a1 a2 a3 b1 b2 b3 c1 c2 c3
+foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar
+```
+
+The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases.
+
+## Brace matching
+
+In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching.
+
+For example, the pattern `foo/{1..3}/bar` would match any of following strings:
+
+```
+foo/1/bar
+foo/2/bar
+foo/3/bar
+```
+
+But not:
+
+```
+baz/1/qux
+baz/2/qux
+baz/3/qux
+```
+
+Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings:
+
+```
+foo/1/bar
+foo/2/bar
+foo/3/bar
+baz/1/qux
+baz/2/qux
+baz/3/qux
+```
+
+## Brace matching pitfalls
+
+Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of.
+
+### tldr
+
+**"brace bombs"**
+
+* brace expansion can eat up a huge amount of processing resources
+* as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially
+* users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!)
+
+For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section.
+
+### The solution
+
+Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries.
+
+### Geometric complexity
+
+At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`.
+
+For example, the following sets demonstrate quadratic (`O(n^2)`) complexity:
+
+```
+{1,2}{3,4}      => (2X2)    => 13 14 23 24
+{1,2}{3,4}{5,6} => (2X2X2)  => 135 136 145 146 235 236 245 246
+```
+
+But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity:
+
+```
+{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 
+                                    249 257 258 259 267 268 269 347 348 349 357 
+                                    358 359 367 368 369
+```
+
+Now, imagine how this complexity grows given that each element is a n-tuple:
+
+```
+{1..100}{1..100}         => (100X100)     => 10,000 elements (38.4 kB)
+{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB)
+```
+
+Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control.

+
+## Performance
+
+Braces is not only screaming fast, it's also more accurate the other brace expansion libraries.
+
+### Better algorithms
+
+Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_.
+
+Instead, convert the pattern into an optimized regular expression. This is easier said than done, and braces is the only library that does this currently.
+
+**The proof is in the numbers**
+
+Minimatch gets exponentially slower as patterns increase in complexity, braces does not. The following results were generated using `braces()` and `minimatch.braceExpand()`, respectively.
+
+| **Pattern**                 | **braces**         | **[minimatch][]**            |

+
+> Minimal and efficient cross-platform file watching library
+
+[![NPM](https://nodei.co/npm/chokidar.png)](https://www.npmjs.com/package/chokidar)
+
+## Why?
+
+Node.js `fs.watch`:
+
+* Doesn't report filenames on MacOS.
+* Doesn't report events at all when using editors like Sublime on MacOS.
+* Often reports events twice.
+* Emits most changes as `rename`.
+* Does not provide an easy way to recursively watch file trees.
+* Does not support recursive watching on Linux.
+
+Node.js `fs.watchFile`:
+
+* Almost as bad at event handling.
+* Also does not provide any recursive watching.
+* Results in high CPU utilization.
+
+Chokidar resolves these problems.
+
+Initially made for **[Brunch](https://brunch.io/)** (an ultra-swift web app build tool), it is now used in
+[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
+[gulp](https://github.com/gulpjs/gulp/),
+[karma](https://karma-runner.github.io/),
+[PM2](https://github.com/Unitech/PM2),
+[browserify](http://browserify.org/),
+[webpack](https://webpack.github.io/),
+[BrowserSync](https://www.browsersync.io/),
+and [many others](https://www.npmjs.com/browse/depended/chokidar).
+It has proven itself in production environments.
+
+Version 3 is out! Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/)
+
+## How?
+
+Chokidar does still rely on the Node.js core `fs` module, but when using
+`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
+receives, often checking for truth by getting file stats and/or dir contents.
+
+On MacOS, chokidar by default uses a native extension exposing the Darwin
+`FSEvents` API. This provides very efficient recursive watching compared with
+implementations like `kqueue` available on most \*nix platforms. Chokidar still
+does have to do some work to normalize the events received that way as well.
+
+On most other platforms, the `fs.watch`-based implementation is the default, which
+avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
+watchers recursively for everything within scope of the paths that have been
+specified, so be judicious about not wasting system resources by watching much
+more than needed.
+
+## Getting started
+
+Install with npm:
+
+```sh
+npm install chokidar
+```
+
+Then `require` and use it in your code:
+
+```javascript
+const chokidar = require('chokidar');
+
+// One-liner for current directory
+chokidar.watch('.').on('all', (event, path) => {
+  console.log(event, path);
+});
+```
+
+## API
+
+```javascript
+// Example of a more typical implementation structure
+
+// Initialize watcher.
+const watcher = chokidar.watch('file, dir, glob, or array', {
+  ignored: /(^|[\/\\])\../, // ignore dotfiles
+  persistent: true
+});
+
+// Something to use when events are received.
+const log = console.log.bind(console);
+// Add event listeners.
+watcher
+  .on('add', path => log(`File ${path} has been added`))
+  .on('change', path => log(`File ${path} has been changed`))
+  .on('unlink', path => log(`File ${path} has been removed`));
+
+// More possible events.
+watcher
+  .on('addDir', path => log(`Directory ${path} has been added`))
+  .on('unlinkDir', path => log(`Directory ${path} has been removed`))
+  .on('error', error => log(`Watcher error: ${error}`))
+  .on('ready', () => log('Initial scan complete. Ready for changes'))
+  .on('raw', (event, path, details) => { // internal
+    log('Raw event info:', event, path, details);
+  });
+
+// 'add', 'addDir' and 'change' events also receive stat() results as second
+// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats
+watcher.on('change', (path, stats) => {
+  if (stats) console.log(`File ${path} changed size to ${stats.size}`);
+});
+
+// Watch new files.
+watcher.add('new-file');
+watcher.add(['new-file-2', 'new-file-3', '**/other-file*']);
+
+// Get list of actual paths being watched on the filesystem
+var watchedPaths = watcher.getWatched();
+
+// Un-watch some files.
+await watcher.unwatch('new-file*');
+
+// Stop watching.
+// The method is async!
+watcher.close().then(() => console.log('closed'));
+
+// Full list of options. See below for descriptions.
+// Do not use this example!

+
+`chokidar.watch(paths, [options])`
+
+* `paths` (string or array of strings). Paths to files, dirs to be watched
+recursively, or glob patterns.
+    - Note: globs must not contain windows separators (`\`),
+    because that's how they work by the standard —
+    you'll need to replace them with forward slashes (`/`).
+    - Note 2: for additional glob documentation, check out low-level
+    library: [picomatch](https://github.com/micromatch/picomatch).
+* `options` (object) Options object as defined below:
+
+#### Persistence
+
+* `persistent` (default: `true`). Indicates whether the process
+should continue to run as long as files are being watched. If set to
+`false` when using `fsevents` to watch, no more events will be emitted
+after `ready`, even if the process continues to run.
+
+#### Path filtering
+
+* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition)
+Defines files/paths to be ignored. The whole relative or absolute path is
+tested, not just filename. If a function with two arguments is provided, it
+gets called twice per path - once with a single argument (the path), second
+time with two arguments (the path and the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object of that path).
+* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
+instantiating the watching as chokidar discovers these file paths (before the `ready` event).
+* `followSymlinks` (default: `true`). When `false`, only the
+symlinks themselves will be watched for changes instead of following
+the link references and bubbling events through the link's path.
+* `cwd` (no default). The base directory from which watch `paths` are to be
+derived. Paths emitted with events will be relative to this.
+* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as
+literal path names, even if they look like globs.
+
+#### Performance
+
+* `usePolling` (default: `false`).
+Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
+leads to high CPU utilization, consider setting this to `false`. It is
+typically necessary to **set this to `true` to successfully watch files over
+a network**, and it may be necessary to successfully watch files in other
+non-standard situations. Setting to `true` explicitly on MacOS overrides the
+`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
+to true (1) or false (0) in order to override this option.
+* _Polling-specific settings_ (effective when `usePolling: true`)
+  * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also
+    set the CHOKIDAR_INTERVAL env variable to override this option.
+  * `binaryInterval` (default: `300`). Interval of file system
+  polling for binary files.
+  ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
+* `useFsEvents` (default: `true` on MacOS). Whether to use the
+`fsevents` watching interface if available. When set to `true` explicitly
+and `fsevents` is available this supercedes the `usePolling` setting. When
+set to `false` on MacOS, `usePolling: true` becomes the default.
+* `alwaysStat` (default: `false`). If relying upon the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object that may get passed with `add`, `addDir`, and `change` events, set
+this to `true` to ensure it is provided even in cases where it wasn't
+already available from the underlying watch events.
+* `depth` (default: `undefined`). If set, limits how many levels of
+subdirectories will be traversed.
+* `awaitWriteFinish` (default: `false`).
+By default, the `add` event will fire when a file first appears on disk, before
+the entire file has been written. Furthermore, in some cases some `change`
+events will be emitted while the file is being written. In some cases,
+especially when watching for large files there will be a need to wait for the
+write operation to finish before responding to a file creation or modification.
+Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
+holding its `add` and `change` events until the size does not change for a
+configurable amount of time. The appropriate duration setting is heavily
+dependent on the OS and hardware. For accurate detection this parameter should
+be relatively high, making file watching much less responsive.
+Use with caution.
+  * *`options.awaitWriteFinish` can be set to an object in order to adjust
+  timing params:*
+  * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
+  milliseconds for a file size to remain constant before emitting its event.
+  * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds.
+
+#### Errors
+
+* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
+that don't have read permissions if possible. If watching fails due to `EPERM`
+or `EACCES` with this set to `true`, the errors will be suppressed silently.
+* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
+Automatically filters out artifacts that occur when using editors that use
+"atomic writes" instead of writing directly to the source file. If a file is
+re-added within 100 ms of being deleted, Chokidar emits a `change` event
+rather than `unlink` then `add`. If the default of 100 ms does not work well
+for you, you can override it by setting `atomic` to a custom value, in
+milliseconds.
+
+### Methods & Events
+
+`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
+
+* `.add(path / paths)`: Add files, directories, or glob patterns for tracking.
+Takes an array of strings or just one string.
+* `.on(event, callback)`: Listen for an FS event.
+Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
+`raw`, `error`.
+Additionally `all` is available which gets emitted with the underlying event
+name and path for every event other than `ready`, `raw`, and `error`.  `raw` is internal, use it carefully.
+* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
+Takes an array of strings or just one string.
+* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen.
+* `.getWatched()`: Returns an object representing all the paths on the file
+system being watched by this `FSWatcher` instance. The object's keys are all the
+directories (using absolute paths unless the `cwd` option was used), and the
+values are arrays of the names of the items contained in each directory.
+
+## CLI
+
+If you need a CLI interface for your file watching, check out
+[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to
+execute a command on each change, or get a stdio stream of change events.
+
+## Install Troubleshooting
+
+* `npm WARN optional dep failed, continuing fsevents@n.n.n`
+  * This message is normal part of how `npm` handles optional dependencies and is
+    not indicative of a problem. Even if accompanied by other related error messages,
+    Chokidar should function properly.
+
+* `TypeError: fsevents is not a constructor`
+  * Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar.
+
+* Chokidar is producing `ENOSP` error on Linux, like this:
+  * `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell`
+  `Error: watch /home/ ENOSPC`
+  * This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal:
+  `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`
+
+## Changelog

+- **v3.1 (Sep 16, 2019):** dotfiles are no longer filtered out by default. Use `ignored` option if needed. Improve initial Linux scan time by 50%.
+- **v3 (Apr 30, 2019):** massive CPU & RAM consumption improvements; reduces deps / package size by a factor of 17x and bumps Node.js requirement to v8.16 and higher.
+- **v2 (Dec 29, 2017):** Globs are now posix-style-only; without windows support. Tons of bugfixes.
+- **v1 (Apr 7, 2015):** Glob support, symlink support, tons of bugfixes. Node 0.8+ is supported
+- **v0.1 (Apr 20, 2012):** Initial release, extracted from [Brunch](https://github.com/brunch/brunch/blob/9847a065aea300da99bd0753f90354cde9de1261/src/helpers.coffee#L66)
+
+## Also
+
+Why was chokidar named this way? What's the meaning behind it?
+
+>Chowkidar is a transliteration of a Hindi word meaning 'watchman, gatekeeper', चौकीदार. This ultimately comes from Sanskrit _ चतुष्क_ (crossway, quadrangle, consisting-of-four).

+
+> Fill in a range of numbers or letters, optionally passing an increment or `step` to use, or create a regex-compatible range with `options.toRegex`
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save fill-range
+```
+
+## Usage
+
+Expands numbers and letters, optionally using a `step` as the last argument. _(Numbers may be defined as JavaScript numbers or strings)_.
+
+```js
+const fill = require('fill-range');
+// fill(from, to[, step, options]);
+
+console.log(fill('1', '10')); //=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
+console.log(fill('1', '10', { toRegex: true })); //=> [1-9]|10
+```
+
+**Params**
+
+* `from`: **{String|Number}** the number or letter to start with
+* `to`: **{String|Number}** the number or letter to end with
+* `step`: **{String|Number|Object|Function}** Optionally pass a [step](#optionsstep) to use.
+* `options`: **{Object|Function}**: See all available [options](#options)
+
+## Examples
+
+By default, an array of values is returned.
+
+**Alphabetical ranges**
+
+```js
+console.log(fill('a', 'e')); //=> ['a', 'b', 'c', 'd', 'e']
+console.log(fill('A', 'E')); //=> [ 'A', 'B', 'C', 'D', 'E' ]
+```
+
+**Numerical ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill(1, 5));     //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill('1', '5')); //=> [ 1, 2, 3, 4, 5 ]
+```
+
+**Negative ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill('-5', '-1')); //=> [ '-5', '-4', '-3', '-2', '-1' ]
+console.log(fill('-5', '5')); //=> [ '-5', '-4', '-3', '-2', '-1', '0', '1', '2', '3', '4', '5' ]
+```
+
+**Steps (increments)**
+
+```js
+// numerical ranges with increments
+console.log(fill('0', '25', 4)); //=> [ '0', '4', '8', '12', '16', '20', '24' ]
+console.log(fill('0', '25', 5)); //=> [ '0', '5', '10', '15', '20', '25' ]
+console.log(fill('0', '25', 6)); //=> [ '0', '6', '12', '18', '24' ]
+
+// alphabetical ranges with increments
+console.log(fill('a', 'z', 4)); //=> [ 'a', 'e', 'i', 'm', 'q', 'u', 'y' ]
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 6)); //=> [ 'a', 'g', 'm', 's', 'y' ]
+```
+
+## Options
+
+### options.step
+
+**Type**: `number` (formatted as a string or number)
+
+**Default**: `undefined`
+
+**Description**: The increment to use for the range. Can be used with letters or numbers.
+
+**Example(s)**
+
+```js
+// numbers
+console.log(fill('1', '10', 2)); //=> [ '1', '3', '5', '7', '9' ]
+console.log(fill('1', '10', 3)); //=> [ '1', '4', '7', '10' ]
+console.log(fill('1', '10', 4)); //=> [ '1', '5', '9' ]
+
+// letters
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 7)); //=> [ 'a', 'h', 'o', 'v' ]
+console.log(fill('a', 'z', 9)); //=> [ 'a', 'j', 's' ]
+```
+
+### options.strictRanges
+
+**Type**: `boolean`
+
+**Default**: `false`
+
+**Description**: By default, `null` is returned when an invalid range is passed. Enable this option to throw a `RangeError` on invalid ranges.
+
+**Example(s)**
+
+The following are all invalid:
+
+```js
+fill('1.1', '2');   // decimals not supported in ranges
+fill('a', '2');     // incompatible range values
+fill(1, 10, 'foo'); // invalid "step" argument
+```
+
+### options.stringify
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Cast all returned values to strings. By default, integers are returned as numbers.
+
+**Example(s)**
+
+```js
+console.log(fill(1, 5));                    //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill(1, 5, { stringify: true })); //=> [ '1', '2', '3', '4', '5' ]
+```
+
+### options.toRegex
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Create a regex-compatible source string, instead of expanding values to an array.
+
+**Example(s)**
+
+```js
+// alphabetical range
+console.log(fill('a', 'e', { toRegex: true })); //=> '[a-e]'
+// alphabetical with step
+console.log(fill('a', 'z', 3, { toRegex: true })); //=> 'a|d|g|j|m|p|s|v|y'
+// numerical range
+console.log(fill('1', '100', { toRegex: true })); //=> '[1-9]|[1-9][0-9]|100'
+// numerical range with zero padding
+console.log(fill('000001', '100000', { toRegex: true }));
+//=> '0{5}[1-9]|0{4}[1-9][0-9]|0{3}[1-9][0-9]{2}|0{2}[1-9][0-9]{3}|0[1-9][0-9]{4}|100000'
+```
+
+### options.transform
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+**Description**: Customize each value in the returned array (or [string](#optionstoRegex)). _(you can also pass this function as the last argument to `fill()`)_.
+
+**Example(s)**
+
+```js
+// add zero padding
+console.log(fill(1, 5, value => String(value).padStart(4, '0')));
+//=> ['0001', '0002', '0003', '0004', '0005']
+```

+
+Extract the non-magic parent path from a glob string.
+
+## Usage
+
+```js
+var globParent = require('glob-parent');
+
+globParent('path/to/*.js'); // 'path/to'
+globParent('/root/path/to/*.js'); // '/root/path/to'
+globParent('/*.js'); // '/'
+globParent('*.js'); // '.'
+globParent('**/*.js'); // '.'
+globParent('path/{to,from}'); // 'path'
+globParent('path/!(to|from)'); // 'path'
+globParent('path/?(to|from)'); // 'path'
+globParent('path/+(to|from)'); // 'path'
+globParent('path/*(to|from)'); // 'path'
+globParent('path/@(to|from)'); // 'path'
+globParent('path/**/*'); // 'path'
+
+// if provided a non-glob path, returns the nearest dir
+globParent('path/foo/bar.js'); // 'path/foo'
+globParent('path/foo/'); // 'path/foo'
+globParent('path/foo'); // 'path' (see issue #3 for details)
+```
+
+## API
+
+### `globParent(maybeGlobString, [options])`
+
+Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.
+
+#### options
+
+```js
+{
+  // Disables the automatic conversion of slashes for Windows
+  flipBackslashes: true
+}
+```
+
+## Escaping
+
+The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
+
+- `?` (question mark) unless used as a path segment alone
+- `*` (asterisk)
+- `|` (pipe)
+- `(` (opening parenthesis)
+- `)` (closing parenthesis)
+- `{` (opening curly brace)
+- `}` (closing curly brace)
+- `[` (opening bracket)
+- `]` (closing bracket)
+
+**Example**
+
+```js
+globParent('foo/[bar]/') // 'foo'
+globParent('foo/\\[bar]/') // 'foo/[bar]'
+```
+
+## Limitations
+
+### Braces & Brackets
+This library attempts a quick and imperfect method of determining which path
+parts have glob magic without fully parsing/lexing the pattern. There are some
+advanced use cases that can trip it up, such as nested braces where the outer
+pair is escaped and the inner one contains a path separator. If you find
+yourself in the unlikely circumstance of being affected by this or need to
+ensure higher-fidelity glob handling in your library, it is recommended that you
+pre-process your input with [expand-braces] and/or [expand-brackets].
+
+### Windows
+Backslashes are not valid path separators for globs. If a path with backslashes
+is provided anyway, for simple cases, glob-parent will replace the path
+separator for you and return the non-glob parent path (now with
+forward-slashes, which are still valid as Windows path separators).
+
+This cannot be used in conjunction with escape characters.
+
+```js
+// BAD
+globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)'
+
+// GOOD
+globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)'
+```
+
+If you are using escape characters for a pattern without path parts (i.e.
+relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
+
+```js
+// BAD
+globParent('foo \\[bar]') // 'foo '
+globParent('foo \\[bar]*') // 'foo '
+
+// GOOD
+globParent('./foo \\[bar]') // 'foo [bar]'
+globParent('./foo \\[bar]*') // '.'
+```

+
+> Returns true if the value is a finite number.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-number
+```
+
+## Why is this needed?
+
+In JavaScript, it's not always as straightforward as it should be to reliably check if a value is a number. It's common for devs to use `+`, `-`, or `Number()` to cast a string value to a number (for example, when values are returned from user input, regex matches, parsers, etc). But there are many non-intuitive edge cases that yield unexpected results:
+
+```js
+console.log(+[]); //=> 0
+console.log(+''); //=> 0
+console.log(+'   '); //=> 0
+console.log(typeof NaN); //=> 'number'
+```
+
+This library offers a performant way to smooth out edge cases like these.
+
+## Usage
+
+```js
+const isNumber = require('is-number');
+```
+
+See the [tests](./test.js) for more examples.
+
+### true
+
+```js
+isNumber(5e3);               // true
+isNumber(0xff);              // true
+isNumber(-1.1);              // true
+isNumber(0);                 // true
+isNumber(1);                 // true
+isNumber(1.1);               // true
+isNumber(10);                // true
+isNumber(10.10);             // true
+isNumber(100);               // true
+isNumber('-1.1');            // true
+isNumber('0');               // true
+isNumber('012');             // true
+isNumber('0xff');            // true
+isNumber('1');               // true
+isNumber('1.1');             // true
+isNumber('10');              // true
+isNumber('10.10');           // true
+isNumber('100');             // true
+isNumber('5e3');             // true
+isNumber(parseInt('012'));   // true
+isNumber(parseFloat('012')); // true
+```
+
+### False
+
+Everything else is false, as you would expect:
+
+```js
+isNumber(Infinity);          // false
+isNumber(NaN);               // false
+isNumber(null);              // false
+isNumber(undefined);         // false
+isNumber('');                // false
+isNumber('   ');             // false
+isNumber('foo');             // false
+isNumber([1]);               // false
+isNumber([]);                // false
+isNumber(function () {});    // false
+isNumber({});                // false
+```
+
+## Release history
+
+### 7.0.0
+
+* Refactor. Now uses `.isFinite` if it exists.
+* Performance is about the same as v6.0 when the value is a string or number. But it's now 3x-4x faster when the value is not a string or number.
+
+### 6.0.0
+
+* Optimizations, thanks to @benaadams.
+
+### 5.0.0
+
+**Breaking changes**
+
+* removed support for `instanceof Number` and `instanceof String`
+
+## Benchmarks

+# readdirp [![Weekly downloads](https://img.shields.io/npm/dw/readdirp.svg)](https://github.com/paulmillr/readdirp)
+
+Recursive version of [fs.readdir](https://nodejs.org/api/fs.html#fs_fs_readdir_path_options_callback). Exposes a **stream API** and a **promise API**.
+
+
+```sh
+npm install readdirp
+```
+
+```javascript
+const readdirp = require('readdirp');
+
+// Use streams to achieve small RAM & CPU footprint.
+// 1) Streams example with for-await.
+for await (const entry of readdirp('.')) {
+  const {path} = entry;
+  console.log(`${JSON.stringify({path})}`);
+}
+
+// 2) Streams example, non for-await.
+// Print out all JS files along with their size within the current folder & subfolders.
+readdirp('.', {fileFilter: '*.js', alwaysStat: true})
+  .on('data', (entry) => {
+    const {path, stats: {size}} = entry;
+    console.log(`${JSON.stringify({path, size})}`);
+  })
+  // Optionally call stream.destroy() in `warn()` in order to abort and cause 'close' to be emitted
+  .on('warn', error => console.error('non-fatal error', error))
+  .on('error', error => console.error('fatal error', error))
+  .on('end', () => console.log('done'));
+
+// 3) Promise example. More RAM and CPU than streams / for-await.
+const files = await readdirp.promise('.');
+console.log(files.map(file => file.path));
+
+// Other options.
+readdirp('test', {
+  fileFilter: '*.js',
+  directoryFilter: ['!.git', '!*modules']
+  // directoryFilter: (di) => di.basename.length === 9
+  type: 'files_directories',
+  depth: 1
+});
+```
+
+For more examples, check out `examples` directory.
+
+## API
+
+`const stream = readdirp(root[, options])` — **Stream API**
+
+- Reads given root recursively and returns a `stream` of [entry infos](#entryinfo)
+- Optionally can be used like `for await (const entry of stream)` with node.js 10+ (`asyncIterator`).
+- `on('data', (entry) => {})` [entry info](#entryinfo) for every file / dir.
+- `on('warn', (error) => {})` non-fatal `Error` that prevents a file / dir from being processed. Example: inaccessible to the user.
+- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed.
+- `on('end')` — we are done. Called when all entries were found and no more will be emitted.
+- `on('close')` — stream is destroyed via `stream.destroy()`.
+  Could be useful if you want to manually abort even on a non fatal error.
+  At that point the stream is no longer `readable` and no more entries, warning or errors are emitted
+- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html)
+  or the [stream-handbook](https://github.com/substack/stream-handbook)
+
+`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo).
+
+First argument is awalys `root`, path in which to start reading and recursing into subdirectories.
+
+### options
+
+- `fileFilter: ["*.js"]`: filter to include or exclude files. A `Function`, Glob string or Array of glob strings.
+    - **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
+    - **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more
+        information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files.
+    - **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown.
+        `['*.json', '*.js']` includes all JavaScript and Json files.
+        `['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'.
+    - Directories that do not pass a filter will not be recursed into.
+- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into.
+- `depth: 5`: depth at which to stop recursing even if more subdirectories are found
+- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes.
+- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0.
+- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat`
+
+### `EntryInfo`
+
+Has the following properties:
+
+- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root)
+- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found
+- `basename: 'react.js'`: name of the file/directory
+- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false`
+- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true`
+
+## Changelog
+
+- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks.
+  Before, it could have entered infinite loop.
+- 3.4 (Mar 19, 2020) adds support for directory-based symlinks.
+- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping.
+- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic.
+- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions".
+- 3.0 brings huge performance improvements and stream backpressure support.
+- Upgrading 2.x to 3.x:
+    - Signature changed from `readdirp(options)` to `readdirp(root, options)`
+    - Replaced callback API with promise API.
+    - Renamed `entryType` option to `type`
+    - Renamed `entryType: 'both'` to `'files_directories'`
+    - `EntryInfo`
+        - Renamed `stat` to `stats`
+            - Emitted only when `alwaysStat: true`
+            - `dirent` is emitted instead of `stats` by default with `alwaysStat: false`
+        - Renamed `name` to `basename`
+        - Removed `parentDir` and `fullParentDir` properties
+- Supported node.js versions:
+    - 3.x: node 8+
+    - 2.x: node 0.6+

+
+> Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save to-regex-range
+```
+
+

+What does this do?
+
+

+
+This libary generates the `source` string to be passed to `new RegExp()` for matching a range of numbers.
+
+**Example**
+
+```js
+const toRegexRange = require('to-regex-range');
+const regex = new RegExp(toRegexRange('15', '95'));
+```
+
+A string is returned so that you can do whatever you need with it before passing it to `new RegExp()` (like adding `^` or `$` boundaries, defining flags, or combining it another string).
+
+

+
+

+
+

+Why use this library?
+
+

+
+### Convenience
+
+Creating regular expressions for matching numbers gets deceptively complicated pretty fast.
+
+For example, let's say you need a validation regex for matching part of a user-id, postal code, social security number, tax id, etc:
+
+* regex for matching `1` => `/1/` (easy enough)
+* regex for matching `1` through `5` => `/[1-5]/` (not bad...)
+* regex for matching `1` or `5` => `/(1|5)/` (still easy...)
+* regex for matching `1` through `50` => `/([1-9]|[1-4][0-9]|50)/` (uh-oh...)
+* regex for matching `1` through `55` => `/([1-9]|[1-4][0-9]|5[0-5])/` (no prob, I can do this...)
+* regex for matching `1` through `555` => `/([1-9]|[1-9][0-9]|[1-4][0-9]{2}|5[0-4][0-9]|55[0-5])/` (maybe not...)
+* regex for matching `0001` through `5555` => `/(0{3}[1-9]|0{2}[1-9][0-9]|0[1-9][0-9]{2}|[1-4][0-9]{3}|5[0-4][0-9]{2}|55[0-4][0-9]|555[0-5])/` (okay, I get the point!)
+
+The numbers are contrived, but they're also really basic. In the real world you might need to generate a regex on-the-fly for validation.
+
+**Learn more**
+
+If you're interested in learning more about [character classes](http://www.regular-expressions.info/charclass.html) and other regex features, I personally have always found [regular-expressions.info](http://www.regular-expressions.info/charclass.html) to be pretty useful.
+
+### Heavily tested
+
+As of April 07, 2019, this library runs [>1m test assertions](./test/test.js) against generated regex-ranges to provide brute-force verification that results are correct.
+
+Tests run in ~280ms on my MacBook Pro, 2.5 GHz Intel Core i7.
+
+### Optimized
+
+Generated regular expressions are optimized:
+
+* duplicate sequences and character classes are reduced using quantifiers
+* smart enough to use `?` conditionals when number(s) or range(s) can be positive or negative
+* uses fragment caching to avoid processing the same exact string more than once
+
+

+
+

+
+## Usage
+
+Add this library to your javascript application with the following line of code
+
+```js
+const toRegexRange = require('to-regex-range');
+```
+
+The main export is a function that takes two integers: the `min` value and `max` value (formatted as strings or numbers).
+
+```js
+const source = toRegexRange('15', '95');
+//=> 1[5-9]|[2-8][0-9]|9[0-5]
+
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('14')); //=> false
+console.log(regex.test('50')); //=> true
+console.log(regex.test('94')); //=> true
+console.log(regex.test('96')); //=> false
+```
+
+## Options
+
+### options.capture
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Wrap the returned value in parentheses when there is more than one regex condition. Useful when you're dynamically generating ranges.
+
+```js
+console.log(toRegexRange('-10', '10'));
+//=> -[1-9]|-?10|[0-9]
+
+console.log(toRegexRange('-10', '10', { capture: true }));
+//=> (-[1-9]|-?10|[0-9])
+```
+
+### options.shorthand
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Use the regex shorthand for `[0-9]`:
+
+```js
+console.log(toRegexRange('0', '999999'));
+//=> [0-9]|[1-9][0-9]{1,5}
+
+console.log(toRegexRange('0', '999999', { shorthand: true }));
+//=> \d|[1-9]\d{1,5}
+```
+
+### options.relaxZeros
+
+**Type**: `boolean`
+
+**Default**: `true`
+
+This option relaxes matching for leading zeros when when ranges are zero-padded.
+
+```js
+const source = toRegexRange('-0010', '0010');
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> true
+console.log(regex.test('-010')); //=> true
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> true
+console.log(regex.test('010')); //=> true
+console.log(regex.test('0010')); //=> true
+```
+
+When `relaxZeros` is false, matching is strict:
+
+```js
+const source = toRegexRange('-0010', '0010', { relaxZeros: false });
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> false
+console.log(regex.test('-010')); //=> false
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> false
+console.log(regex.test('010')); //=> false
+console.log(regex.test('0010')); //=> true
+```

+
+## Heads up!
+
+**Order of arguments**
+
+When the `min` is larger than the `max`, values will be flipped to create a valid range:
+
+```js
+toRegexRange('51', '29');
+```
+
+Is effectively flipped to:
+
+```js
+toRegexRange('29', '51');
+//=> 29|[3-4][0-9]|5[0-1]
+```
+
+**Steps / increments**
+
+This library does not support steps (increments). A pr to add support would be welcome.
+
+## History
+
+### v2.0.0 - 2017-04-21
+
+**New features**
+
+Adds support for zero-padding!
+
+### v1.0.0
+
+**Optimizations**
+
+Repeating ranges are now grouped using quantifiers. rocessing time is roughly the same, but the generated regex is much smaller, which should result in faster matching.

+//    is loaded. It should load and eval the javascript of `uri`, and call
+//    successCallback. If it fails to do so, it should call errorCallback with
+//    an error. The loadId argument is the deferred import that resulted in

+//
+// dartCallInstrumentation(id, qualifiedName):
+//    if this function is defined, it will be called at each entry of a
+//    method or constructor. Used only when compiling programs with
+//    --experiment-call-instrumentation.

+ * @example Resolving a Load
+ *
+ * This is the process of resolving a load using a custom importer:
+ *
+ * - The compiler encounters `@use "db:foo/bar/baz"`.
+ * - It calls [[canonicalize]] with `"db:foo/bar/baz"`.
+ * - [[canonicalize]] returns `new URL("db:foo/bar/baz/_index.scss")`.
+ * - If the compiler has already loaded a stylesheet with this canonical URL, it
+ *   re-uses the existing module.
+ * - Otherwise, it calls [[load]] with `new URL("db:foo/bar/baz/_index.scss")`.
+ * - [[load]] returns an [[ImporterResult]] that the compiler uses as the
+ *   contents of the module.
+ *
+ * @example Code Sample
+ *
+ * ```js
+ * sass.compile('style.scss', {
+ *   // An importer for URLs like `bgcolor:orange` that generates a
+ *   // stylesheet with the given background color.
+ *   importers: [{

+   *
+   * As much as possible, custom importers should canonicalize URLs the same way
+   * as the built-in filesystem importer:
+   *
+   * - The importer should look for stylesheets by adding the prefix `_` to the
+   *   URL's basename, and by adding the extensions `.sass` and `.scss` if the
+   *   URL doesn't already have one of those extensions. For example, if the
+   *   URL was `foo/bar/baz`, the importer would look for:
+   *   - `foo/bar/baz.sass`
+   *   - `foo/bar/baz.scss`
+   *   - `foo/bar/_baz.sass`
+   *   - `foo/bar/_baz.scss`
+   *
+   *   If the URL was `foo/bar/baz.scss`, the importer would just look for:
+   *   - `foo/bar/baz.scss`
+   *   - `foo/bar/_baz.scss`
+   *
+   *   If the importer finds a stylesheet at more than one of these URLs, it
+   *   should throw an exception indicating that the URL is ambiguous. Note that
+   *   if the extension is explicitly specified, a stylesheet with the opposite
+   *   extension is allowed to exist.
+   *
+   * - If none of the possible paths is valid, the importer should perform the
+   *   same resolution on the URL followed by `/index`. In the example above,
+   *   it would look for:
+   *   - `foo/bar/baz/index.sass`
+   *   - `foo/bar/baz/index.scss`
+   *   - `foo/bar/baz/_index.sass`
+   *   - `foo/bar/baz/_index.scss`
+   *
+   *   As above, if the importer finds a stylesheet at more than one of these
+   *   URLs, it should throw an exception indicating that the import is
+   *   ambiguous.
+   *
+   * If no stylesheets are found, the importer should return `null`.
+   *
+   * Calling [[canonicalize]] multiple times with the same URL must return the
+   * same result. Calling [[canonicalize]] with a URL returned by a previous
+   * call to [[canonicalize]] must return that URL.
+   *
+   * Relative loads in stylesheets loaded from an importer are handled by
+   * resolving the loaded URL relative to the canonical URL of the stylesheet
+   * that contains it, and passing that URL back to the importer's
+   * [[canonicalize]] method. For example, suppose the "Resolving a Load"
+   * example {@link Importer | above} returned a stylesheet that contained
+   * `@use "mixins"`:
+   *
+   * - The compiler resolves the URL `mixins` relative to the current
+   *   stylesheet's canonical URL `db:foo/bar/baz/_index.scss` to get
+   *   `db:foo/bar/baz/mixins`.
+   * - It calls [[canonicalize]] with `"db:foo/bar/baz/mixins"`.
+   * - [[canonicalize]] returns `new URL("db:foo/bar/baz/_mixins.scss")`.
+   *
+   * Because of this, [[canonicalize]] must return a meaningful result when
+   * called with a URL relative to one returned by an earlier call to
+   * [[canonicalize]].
+   *
+   * @param url - The loaded URL. Since this might be relative, it's represented
+   * as a string rather than a [[URL]] object.
+   *
+   * @param options.fromImport - Whether this is being invoked because of a Sass
+   * `@import` rule, as opposed to a `@use` or `@forward` rule.
+   *
+   * This should *only* be used for determining whether or not to load
+   * [import-only files](https://sass-lang.com/documentation/at-rules/import#import-only-files).
+   *
+   * @returns An absolute URL if this importer recognizes the `url`, or `null`
+   * if it doesn't. If this returns `null`, other importers or {@link
+   * Options.loadPaths | load paths} may handle the load.
+   *
+   * This may also return a `Promise`, but if it does the importer may only be
+   * passed to [[compileAsync]] and [[compileStringAsync]], not [[compile]] or
+   * [[compileString]].
+   *
+   * @throws any - If this importer recognizes `url` but determines that it's
+   * invalid, it may throw an exception that will be wrapped by Sass. If the
+   * exception object has a `message` property, it will be used as the wrapped
+   * exception's message; otherwise, the exception object's `toString()` will be
+   * used. This means it's safe for importers to throw plain strings.
