# gulp-spawn
Plugin to spawn a CLI program for piping with
[gulp](https://github.com/wearefractal/gulp). Uses
[spawn](http://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).
## Usage
gulp-spawn options follow
[`child_process.spawn`](http://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options)
conventions.
Not all CLI programs support piping. In fact, many newer ones don't. Some
programs require that you pass certain arguments if you intend to use stdin
and/or stdout. Please check the documentation of the program you intend to
use to ensure piping is supported.
The following example pipes image files to ImageMagick's `convert`. In the case
of `convert`, you must specify a `-` before arguments and after arguments if
you wish to use stdin and stdout, respectively.
```javascript
var spawn = require("gulp-spawn");
// example using ImageMagick's convert
// setting "buffer: false" optional but recommended for heavy I/O
gulp.src("./src/images/*.{jpg,png,gif}", { buffer: false })
.pipe(spawn({
cmd: "convert",
args: [
"-",
"-resize",
"50%",
"-"
],
// optional
filename: function(base, ext) {
return base + "-half" + ext;
}
}))
.pipe(gulp.dest("./dist/images/"));
```
## The UNIX Pipe Philosophy
If you write spawn programs please consider taking the time to support stdin &
stdout. Piping is one of the many reasons UNIX systems have endured the test
of time.
## Changelog
v0.1.0 - Initial Release
v0.2.0 - Added `filename` callback option
v0.2.1 - Fixed support for streams. Effeciency improvements.
v0.3.0 - Latest stream support and error emits.

# ansi-regex [![Build Status](https://travis-ci.org/sindresorhus/ansi-regex.svg?branch=master)](https://travis-ci.org/sindresorhus/ansi-regex)
> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
## Install
```sh
$ npm install --save ansi-regex
```
## Usage
```js
var ansiRegex = require('ansi-regex');
ansiRegex().test('\u001b[4mcake\u001b[0m');
//=> true
ansiRegex().test('cake');
//=> false
'\u001b[4mcake\u001b[0m'.match(ansiRegex());
//=> ['\u001b[4m', '\u001b[0m']
```
*It's a function so you can create multiple instances. Regexes with the global flag will have the `.lastIndex` property changed for each call to methods on the instance. Therefore reusing the instance with multiple calls will not work as expected for `.test()`.*

> Terminal string styling done right
[![Build Status](https://travis-ci.org/sindresorhus/chalk.svg?branch=master)](https://travis-ci.org/sindresorhus/chalk)
![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)
[colors.js](https://github.com/Marak/colors.js) is currently the most popular string styling module, but it has serious deficiencies like extending String.prototype which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
**Chalk is a clean and focused alternative.**
![screenshot](https://github.com/sindresorhus/ansi-styles/raw/master/screenshot.png)
## Why
- Highly performant
- Doesn't extend String.prototype
- Expressive API
- Ability to nest styles
- Clean and focused
- Auto-detects color support
- Actively maintained
- [Used by 1000+ modules](https://npmjs.org/browse/depended/chalk)
## Install
```sh
$ npm install --save chalk
```
## Usage
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
```js
var chalk = require('chalk');
// style a string
console.log( chalk.blue('Hello world!') );
// combine styled and normal strings
console.log( chalk.blue('Hello'), 'World' + chalk.red('!') );
// compose multiple styles using the chainable API
console.log( chalk.blue.bgRed.bold('Hello world!') );
// pass in multiple arguments
console.log( chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz') );
// nest styles
console.log( chalk.red('Hello', chalk.underline.bgBlue('world') + '!') );
// nest styles of the same type even (color, underline, background)
console.log( chalk.green('I am a green line ' + chalk.blue('with a blue substring') + ' that becomes green again!') );
```
Easily define your own themes.
```js
var chalk = require('chalk');
var error = chalk.bold.red;
console.log(error('Error!'));
```
Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
```js
var name = 'Sindre';
console.log(chalk.green('Hello %s'), name);
//=> Hello Sindre
```
## API
### chalk.`<style>[.<style>...](string, [string...])`
Example: `chalk.red.bold.underline('Hello', 'world');`
Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter.
Multiple arguments will be separated by space.
### chalk.enabled
Color support is automatically detected, but you can override it.
### chalk.supportsColor
Detect whether the terminal [supports color](https://github.com/sindresorhus/supports-color).
Can be overridden by the user with the flags `--color` and `--no-color`.
Used internally and handled for you, but exposed for convenience.
### chalk.styles
Exposes the styles as [ANSI escape codes](https://github.com/sindresorhus/ansi-styles).
Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with yours.
```js
var chalk = require('chalk');
console.log(chalk.styles.red);
//=> {open: '\u001b[31m', close: '\u001b[39m'}
console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
```
### chalk.hasColor(string)
Check whether a string [has color](https://github.com/sindresorhus/has-ansi).
### chalk.stripColor(string)
[Strip color](https://github.com/sindresorhus/strip-ansi) from a string.
Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
Example:
```js
var chalk = require('chalk');
var styledString = getText();
if (!chalk.supportsColor) {
styledString = chalk.stripColor(styledString);
}
```
## Styles
### General
- `reset`
- `bold`
- `dim`
- `italic` *(not widely supported)*
- `underline`
- `inverse`
- `hidden`
- `strikethrough` *(not widely supported)*
### Text colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `gray`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`

# dateformat
A node.js package for Steven Levithan's excellent [dateFormat()][dateformat] function.
[![Build Status](https://travis-ci.org/felixge/node-dateformat.svg)](https://travis-ci.org/felixge/node-dateformat)
## Modifications
* Removed the `Date.prototype.format` method. Sorry folks, but extending native prototypes is for suckers.
* Added a `module.exports = dateFormat;` statement at the bottom
* Added the placeholder `N` to get the ISO 8601 numeric representation of the day of the week
## Installation
```bash
$ npm install dateformat
$ dateformat --help
```
## Usage
As taken from Steven's post, modified to match the Modifications listed above:
```js
var dateFormat = require('dateformat');
var now = new Date();
// Basic usage
dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM
// You can use one of several named masks
dateFormat(now, "isoDateTime");
// 2007-06-09T17:46:21
// ...Or add your own
dateFormat.masks.hammerTime = 'HH:MM! "Can\'t touch this!"';
dateFormat(now, "hammerTime");
// 17:46! Can't touch this!
// When using the standalone dateFormat function,
// you can also provide the date as a string
dateFormat("Jun 9 2007", "fullDate");
// Saturday, June 9, 2007
// Note that if you don't include the mask argument,
// dateFormat.masks.default is used
dateFormat(now);
// Sat Jun 09 2007 17:46:21
// And if you don't include the date argument,
// the current date and time is used
dateFormat();
// Sat Jun 09 2007 17:46:22
// You can also skip the date argument (as long as your mask doesn't
// contain any numbers), in which case the current date/time is used
dateFormat("longTime");
// 5:46:22 PM EST
// And finally, you can convert local time to UTC time. Simply pass in
// true as an additional argument (no argument skipping allowed in this case):
dateFormat(now, "longTime", true);
// 10:46:21 PM UTC
// ...Or add the prefix "UTC:" or "GMT:" to your mask.
dateFormat(now, "UTC:h:MM:ss TT Z");
// 10:46:21 PM UTC
// You can also get the ISO 8601 week of the year:
dateFormat(now, "W");
// 42
// and also get the ISO 8601 numeric representation of the day of the week:
dateFormat(now,"N");
// 6
```

# gulp-util [![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Dependency Status][depstat-image]][depstat-url]
## Information
<table>
<tr>
<td>Package</td><td>gulp-util</td>
</tr>
<tr>
<td>Description</td>
<td>Utility functions for gulp plugins</td>
</tr>
<tr>
<td>Node Version</td>
<td>>= 0.9</td>
</tr>
</table>
## Usage
```javascript
var gutil = require('gulp-util');
gutil.log('stuff happened', 'Really it did', gutil.colors.cyan('123'));
gutil.beep();
gutil.replaceExtension('file.coffee', '.js'); // file.js
var opt = {
name: 'todd',
file: someGulpFile
};
gutil.template('test <%= name %> <%= file.path %>', opt) // test todd /js/hi.js
```
### log(msg...)
Logs stuff. Already prefixed with [gulp] and all that. Use the right colors for values. If you pass in multiple arguments it will join them by a space.
```
values (files, module names, etc.) = magenta
numbers (times, counts, etc) = cyan
```
### replaceExtension(path, newExtension)
Replaces a file extension in a path. Returns the new path.
### isStream(obj)
Returns true or false if an object is a stream.
### isBuffer(obj)
Returns true or false if an object is a Buffer.
### template(string[, data])
This is a lodash.template function wrapper. You must pass in a valid gulp file object so it is available to the user or it will error. You can not configure any of the delimiters. Look at the [lodash docs](http://lodash.com/docs#template) for more info.
## new File(obj)
This is just [vinyl](https://github.com/wearefractal/vinyl)
```javascript
var file = new gutil.File({
base: join(__dirname, './fixtures/'),
cwd: __dirname,
path: join(__dirname, './fixtures/test.coffee')
});
```
## noop()
Returns a stream that does nothing but pass data straight through.
```javascript
// gulp should be called like this :
// $ gulp --type production
gulp.task('scripts', function() {
gulp.src('src/**/*.js')
.pipe(concat('script.js'))
.pipe(gutil.env.type === 'production' ? uglify() : gutil.noop())
.pipe(gulp.dest('dist/');
});
```
## buffer(cb)
This is similar to es.wait but instead of buffering text into one string it buffers anything into an array (so very useful for file objects).
Returns a stream that can be piped to.
The stream will emit one data event after the stream piped to it has ended. The data will be the same array passed to the callback.
Callback is optional and receives two arguments: error and data
```javascript
gulp.src('stuff/*.js')
.pipe(gutil.buffer(function(err, files){
});
```
## new PluginError(pluginName, message[, options])
- pluginName should be the module name of your plugin
- message can be a string or an existing error
- 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 in as the message the stack will be pulled from that, otherwise one will be created.
- Note that if you pass in a custom stack string you need to include the message along with that.
These are all acceptable forms of instantiation:
```javascript
var err = new gutil.PluginError('test', {
message: 'something broke'
});
var err = new gutil.PluginError({
plugin: 'test',
message: 'something broke'

* var compiled = _.template('hello <%= name %>');

* var list = '<% _.forEach(people, function(name) { %><li><%- name %></li><% }); %>';
* _.template(list, { 'people': ['fred', 'barney'] });
* // => '<li>fred</li><li>barney</li>'
*
* // using the ES6 delimiter as an alternative to the default "interpolate" delimiter
* _.template('hello ${ name }', { 'name': 'pebbles' });
* // => 'hello pebbles'
*
* // using the internal `print` function in "evaluate" delimiters
* _.template('<% print("hello " + name); %>!', { 'name': 'barney' });
* // => 'hello barney!'

* // using a custom template delimiters
* _.templateSettings = {
* 'interpolate': /{{([\s\S]+?)}}/g
* };
*
* _.template('hello {{ name }}!', { 'name': 'mustache' });
* // => 'hello mustache!'

* _.template(list, { 'people': ['fred', 'barney'] }, { 'imports': { 'jq': jQuery } });

# example
``` js
var argv = require('minimist')(process.argv.slice(2));
console.dir(argv);
```
```
$ node example/parse.js -a beep -b boop
{ _: [], a: 'beep', b: 'boop' }
```
```
$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
{ _: [ 'foo', 'bar', 'baz' ],
x: 3,
y: 4,
n: 5,
a: true,
b: true,
c: true,
beep: 'boop' }
```
# methods
``` js
var parseArgs = require('minimist')
```
## var argv = parseArgs(args, opts={})
Return an argument object `argv` populated with the array arguments from `args`.
`argv._` contains all the arguments that didn't have an option associated with
them.
Numeric-looking arguments will be returned as numbers unless `opts.string` or
`opts.boolean` is set for that argument name.
Any arguments after `'--'` will not be parsed and will end up in `argv._`.
options can be:
* `opts.string` - a string or array of strings argument names to always treat as
strings
* `opts.boolean` - a boolean, string or array of strings to always treat as
booleans. if `true` will treat all double hyphenated arguments without equal signs
as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
* `opts.alias` - an object mapping string names to strings or arrays of string
argument names to use as aliases
* `opts.default` - an object mapping string argument names to default values
* `opts['--']` - when true, populate `argv._` with everything before the `--`
and `argv['--']` with everything after the `--`. Here's an example:
```
> require('./')('one two three -- four five --six'.split(' '), { '--': true })
{ _: [ 'one', 'two', 'three' ],
'--': [ 'four', 'five', '--six' ] }
```
Note that with `opts['--']` set, parsing for arguments still stops after the
`--`.

# readable-stream
***Node-core streams for userland***
[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
[![NPM](https://nodei.co/npm-dl/readable-stream.png?&months=6&height=3)](https://nodei.co/npm/readable-stream/)
This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
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.
**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

// 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.
