## Support

Lo-Dash has been tested in at least Chrome 5~24, Firefox 1~18, IE 6-10, Opera 9.25-12, Safari 3-6, Node.js 0.4.8-0.8.20, Narwhal 0.3.2, PhantomJS 1.8.1, RingoJS 0.9, and Rhino 1.7RC5.

## Custom builds

Custom builds make it easy to create lightweight versions of Lo-Dash containing only the methods you need.
To top it off, we handle all method dependency and alias mapping for you.

 * Backbone builds, with only methods required by Backbone, may be created using the `backbone` modifier argument.
```bash
lodash backbone
```

 * CSP builds, supporting default [Content Security Policy](https://dvcs.w3.org/hg/content-security-policy/raw-file/tip/csp-specification.dev.html) restrictions, may be created using the `csp` modifier argument.
   The `csp` modifier is an alais of the `mobile` modifier. Lo-Dash may be used in Chrome extensions by using either the `csp`, `mobile`, or `underscore` build and using precompiled templates, or loading Lo-Dash in a [sandbox](http://developer.chrome.com/stable/extensions/sandboxingEval.html).
```bash
lodash csp
```

 * Legacy builds, tailored for older environments without [ES5 support](http://es5.github.com/), may be created using the `legacy` modifier argument.
```bash
lodash legacy
```

 * Modern builds, tailored for newer environments with ES5 support, may be created using the `modern` modifier argument.
```bash
lodash modern
```

 * Mobile builds, without method compilation and most bug fixes for old browsers, may be created using the `mobile` modifier argument.
```bash
lodash mobile
```

 * Strict builds, with `_.bindAll`, `_.defaults`, and `_.extend` in [strict mode](http://es5.github.com/#C), may be created using the `strict` modifier argument.
```bash
lodash strict
```

 * Underscore builds, tailored for projects already using Underscore, may be created using the `underscore` modifier argument.
```bash
lodash underscore
```

Custom builds may be created using the following commands:

 * Use the `category` argument to pass comma separated categories of methods to include in the build.<br>
   Valid categories (case-insensitive) are *“arrays”*, *“chaining”*, *“collections”*, *“functions”*, *“objects”*, and *“utilities”*.
```bash
lodash category=collections,functions
lodash category="collections, functions"
```

 * Use the `exports` argument to pass comma separated names of ways to export the `LoDash` function.<br>
   Valid exports are *“amd”*, *“commonjs”*, *“global”*, *“node”*, and *“none”*.
```bash
lodash exports=amd,commonjs,node
lodash exports="amd, commonjs, node"
```

 * Use the `iife` argument to specify code to replace the immediately-invoked function expression that wraps Lo-Dash.
```bash
lodash iife="!function(window,undefined){%output%}(this)"
```

 * Use the `include` argument to pass comma separated method/category names to include in the build.
```bash
lodash include=each,filter,map
lodash include="each, filter, map"
```

 * Use the `minus` argument to pass comma separated method/category names to remove from those included in the build.
```bash
lodash underscore minus=result,shuffle
lodash underscore minus="result, shuffle"
```

 * Use the `plus` argument to pass comma separated method/category names to add to those included in the build.
```bash
lodash backbone plus=random,template
lodash backbone plus="random, template"
```

 * Use the `template` argument to pass the file path pattern used to match template files to precompile.
```bash
lodash template="./*.jst"
```

 * Use the `settings` argument to pass the template settings used when precompiling templates.
```bash
lodash settings="{interpolate:/\{\{([\s\S]+?)\}\}/g}"
```

 * Use the `moduleId` argument to specify the AMD module ID of Lo-Dash, which defaults to “lodash”, used by precompiled templates.
```bash
lodash moduleId="underscore"
```

All arguments, except `legacy` with `csp`, `mobile`, `modern`, or `underscore`, may be combined.<br>
Unless specified by `-o` or `--output`, all files created are saved to the current working directory.

The following options are also supported:

 * `-c`, `--stdout` ......... Write output to standard output
 * `-d`, `--debug` ........... Write only the non-minified development output
 * `-h`, `--help` ............. Display help information
 * `-m`, `--minify` ......... Write only the minified production output
 * `-o`, `--output` ......... Write output to a given path/filename
 * `-p`, `--source-map` .. Generate a source map for the minified output, using an optional source map URL
 * `-s`, `--silent` ......... Skip status updates normally logged to the console
 * `-V`, `--version` ....... Output current version of Lo-Dash

The `lodash` command-line utility is available when Lo-Dash is installed as a global package (i.e. `npm install -g lodash`).

## Installation and usage

In browsers:

```html
<script src="lodash.js"></script>
```

Using [`npm`](http://npmjs.org/):

```bash
npm install lodash

npm install -g lodash
npm link lodash
```

To avoid potential issues, update `npm` before installing Lo-Dash:

```bash
npm install npm -g
```

In [Node.js](http://nodejs.org/) and [RingoJS v0.8.0+](http://ringojs.org/):

```js
var _ = require('lodash');

// or as a drop-in replacement for Underscore
var _ = require('lodash/lodash.underscore');
```

**Note:** If Lo-Dash is installed globally, run [`npm link lodash`](http://blog.nodejs.org/2011/03/23/npm-1-0-global-vs-local-installation/) in your project’s root directory before requiring it.

In [RingoJS v0.7.0-](http://ringojs.org/):

```js
var _ = require('lodash')._;
```

In [Rhino](http://www.mozilla.org/rhino/):

```js
load('lodash.js');
```

In an AMD loader like [RequireJS](http://requirejs.org/):

```js
require({
  'paths': {
    'underscore': 'path/to/lodash'
  }
},
['underscore'], function(_) {
  console.log(_.VERSION);
});
```

## Release Notes

### <sup>v1.0.1</sup>

 * Add support for specifying source map URLs in `-p`/`--source-map` build options
 * Ensured the second argument passed to `_.assign` is not treated as a `callback`
 * Ensured `-p`/`--source-map` build options correctly set the `sourceMappingURL`
 * Made `-p`/`--source-map` build options set source map *“sources”* keys based on the builds performed
 * Made `_.defer` use `setImmediate`, in Node.js, when available
 * Made `_.where` search arrays for values regardless of their index position
 * Removed dead code from `_.template`

The full changelog is available [here](https://github.com/bestiejs/lodash/wiki/Changelog).

## BestieJS

Lo-Dash is part of the BestieJS *“Best in Class”* module collection. This means we promote solid browser/environment support, ES5 precedents, unit testing, and plenty of documentation.
