+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+    --- Original
+    +++ New
+    @@ @@
+    -foo
+    +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+  '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+  'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:

+# Environment
+
+This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
+
+[![Latest Stable Version](https://poser.pugx.org/sebastian/environment/v/stable.png)](https://packagist.org/packages/sebastian/environment)
+[![Build Status](https://travis-ci.org/sebastianbergmann/environment.png?branch=master)](https://travis-ci.org/sebastianbergmann/environment)
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/environment
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/environment
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Environment\Runtime;
+
+$runtime = new Runtime;
+
+var_dump($runtime->getNameWithVersion());
+var_dump($runtime->getName());
+var_dump($runtime->getVersion());
+var_dump($runtime->getBinary());
+var_dump($runtime->isHHVM());
+var_dump($runtime->isPHP());
+var_dump($runtime->hasXdebug());
+var_dump($runtime->canCollectCodeCoverage());
+```

+========
+
+[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
+
+This component provides the functionality to export PHP variables for visualization.
+
+## Usage
+
+Exporting:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Exception Object &0000000078de0f0d000000002003a261 (
+    'message' => ''
+    'string' => ''
+    'code' => 0
+    'file' => '/home/sebastianbergmann/test.php'
+    'line' => 34
+    'trace' => Array &0 ()
+    'previous' => null
+)
+*/
+
+print $exporter->export(new Exception);
+```
+
+## Data Types
+
+Exporting simple types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// 46
+print $exporter->export(46);
+
+// 4.0
+print $exporter->export(4.0);
+
+// 'hello, world!'
+print $exporter->export('hello, world!');
+
+// false
+print $exporter->export(false);
+
+// NAN
+print $exporter->export(acos(8));
+
+// -INF
+print $exporter->export(log(0));
+
+// null
+print $exporter->export(null);
+
+// resource(13) of type (stream)
+print $exporter->export(fopen('php://stderr', 'w'));
+
+// Binary String: 0x000102030405
+print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
+```
+
+Exporting complex types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Array &0 (
+    0 => Array &1 (
+        0 => 1
+        1 => 2
+        2 => 3
+    )
+    1 => Array &2 (
+        0 => ''
+        1 => 0
+        2 => false
+    )
+)
+*/
+
+print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
+
+/*
+Array &0 (
+    'self' => Array &1 (
+        'self' => Array &1
+    )
+)
+*/
+
+$array = array();
+$array['self'] = &$array;
+print $exporter->export($array);
+
+/*
+stdClass Object &0000000003a66dcc0000000025e723e2 (
+    'self' => stdClass Object &0000000003a66dcc0000000025e723e2
+)
+*/
+
+$obj = new stdClass();
+$obj->self = $obj;
+print $exporter->export($obj);
+```
+
+Compact exports:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// Array ()
+print $exporter->shortenedExport(array());
+
+// Array (...)
+print $exporter->shortenedExport(array(1,2,3,4,5));
+
+// stdClass Object ()
+print $exporter->shortenedExport(new stdClass);
+
+// Exception Object (...)
+print $exporter->shortenedExport(new Exception);
+
+// this\nis\na\nsuper\nlong\nstring\nt...\nspace
+print $exporter->shortenedExport(
+<<<LONG_STRING
+this
+is
+a
+super
+long
+string
+that
+wraps
+a
+lot
+and
+eats
+up
+a
+lot
+of
+space
+LONG_STRING
+);
+```
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/exporter
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/exporter
