+# Underscore.string [![Build Status](https://secure.travis-ci.org/epeli/underscore.string.png?branch=master)](http://travis-ci.org/epeli/underscore.string) #
+
+
+
+Javascript lacks complete string manipulation operations.
+This an attempt to fill that gap. List of build-in methods can be found
+for example from [Dive Into JavaScript][d].
+
+[d]: http://www.diveintojavascript.com/core-javascript-reference/the-string-object
+
+
+As name states this an extension for [Underscore.js][u], but it can be used
+independently from **_s**-global variable. But with Underscore.js you can
+use Object-Oriented style and chaining:
+
+[u]: http://documentcloud.github.com/underscore/
+
+```javascript
+_("   epeli  ").chain().trim().capitalize().value()
+=> "Epeli"
+```
+
+## Download ##
+
+  * [Development version](https://raw.github.com/epeli/underscore.string/master/lib/underscore.string.js) *Uncompressed with Comments 18kb*
+  * [Production version](https://github.com/epeli/underscore.string/raw/master/dist/underscore.string.min.js) *Minified 7kb*
+
+
+## Node.js installation ##
+
+**npm package**
+
+    npm install underscore.string
+
+**Standalone usage**:
+
+```javascript
+var _s = require('underscore.string');
+```
+
+**Integrate with Underscore.js**:
+
+```javascript
+var _  = require('underscore');
+
+// Import Underscore.string to separate object, because there are conflict functions (include, reverse, contains)
+_.str = require('underscore.string');
+
+// Mix in non-conflict functions to Underscore namespace if you want
+_.mixin(_.str.exports());
+
+// All functions, include conflict, will be available through _.str object
+_.str.include('Underscore.string', 'string'); // => true
+```
+
+## String Functions ##
+
+For availability of functions in this way you need to mix in Underscore.string functions:
+
+```javascript
+_.mixin(_.string.exports());
+```
+
+otherwise functions from examples will be available through _.string or _.str objects:
+
+```javascript
+_.str.capitalize('epeli')
+=> "Epeli"
+```
+
+**capitalize** _.capitalize(string)
+
+Converts first letter of the string to uppercase.
+
+```javascript
+_.capitalize("foo Bar")
+=> "Foo Bar"
+```
+
+**chop** _.chop(string, step)
+
+```javascript
+_.chop('whitespace', 3)

+
+```javascript
+_.str.include("foobar", "ob")
+=> true
+```
+
+**includes** function was removed
+
+But you can create it in this way, for compatibility with previous versions:
+
+```javascript
+_.includes = _.str.include
+```

+**count** _.count(string, substring)
+
+```javascript
+_('Hello world').count('l')

+**unescapeHTML** _.unescapeHTML(string)

+
+## Changelog ##
+
+### 2.0.0 ###
+
+* Added prune, humanize functions
+* Added _.string (_.str) namespace for Underscore.string library
+* Removed includes function
+
+#### Problems
+
+We lose two things for `include` and `reverse` methods from `_.string`:
+
+* Calls like `_('foobar').include('bar')` aren't available;
+* Chaining isn't available too.
+
+But if you need this functionality you can create aliases for conflict functions which will be convenient for you:
+
+```javascript
+_.mixin({
+    includeString: _.str.include,
+    reverseString: _.str.reverse
+})
+
+// Now wrapper calls and chaining are available.
+_('foobar').chain().reverseString().includeString('rab').value()
+```
+
+#### Standalone Usage
+
+If you are using Underscore.string without Underscore. You also have `_.string` namespace for it and `_.str` alias
+But of course you can just reassign `_` variable with `_.string`
+
+```javascript
+_ = _.string
+```
+### 2.2.0 ###
+
+* Capitalize method behavior changed
+* Various perfomance tweaks
+
+### 2.1.1###
+
+* Fixed words method bug
+* Added classify method
+
+### 2.1.0 ###
+
+* AMD support
+* Added toSentence method
+* Added slugify method
+* Lots of speed optimizations
+
+### 2.0.0 ###
+
+For upgrading to this version you need to mix in Underscore.string library to Underscore object:
+
+```javascript
+_.mixin(_.string.exports());
+```
+
+and all non-conflict Underscore.string functions will be available through Underscore object.
+Also function `includes` has been removed, you should replace this function by `_.str.include`
+or create alias `_.includes = _.str.include` and all your code will work fine.
+
+### 1.1.6 ###
+
+* Fixed reverse and truncate
+* Added isBlank, stripTags, inlude(alias for includes)
+* Added uglifier compression
+
+### 1.1.5 ###
+
+* Added strRight, strRightBack, strLeft, strLeftBack
+
+### 1.1.4 ###
+
+* Added pad, lpad, rpad, lrpad methods and aliases center, ljust, rjust
+* Integration with Underscore 1.1.6
+
+### 1.1.3 ###
+
+* Added methods: underscored, camelize, dasherize
+* Support newer version of npm
+
+### 1.1.2 ###
+
+* Created functions: lines, chars, words functions
+
+### 1.0.2 ###
+
+* Created integration test suite with underscore.js 1.1.4 (now it's absolutely compatible)
+* Removed 'reverse' function, because this function override underscore.js 'reverse'
