+# Stack/Cors
+
+Library and middleware enabling cross-origin resource sharing for your
+http-{foundation,kernel} using application. It attempts to implement the
+[W3C Recommendation] for cross-origin resource sharing.
+
+[W3C Recommendation]: http://www.w3.org/TR/cors/
+
+Master [![Build Status](https://secure.travis-ci.org/asm89/stack-cors.png?branch=master)](http://travis-ci.org/asm89/stack-cors)
+
+## Installation
+
+Require `asm89/stack-cors` using composer.
+
+## Usage
+
+This package can be used as a library or as [stack middleware].
+
+[stack middleware]: http://stackphp.com/
+
+### Options
+
+| Option                 | Description                                                | Default value |
+|------------------------|------------------------------------------------------------|---------------|
+| allowedMethods         | Matches the request method.                                | `array()`     |
+| allowedOrigins         | Matches the request origin.                                | `array()`     |
+| allowedOriginsPatterns | Matches the request origin with `preg_match`.              | `array()`  |
+| allowedHeaders         | Sets the Access-Control-Allow-Headers response header.     | `array()`     |
+| exposedHeaders         | Sets the Access-Control-Expose-Headers response header.    | `false`       |
+| maxAge                 | Sets the Access-Control-Max-Age response header.           | `false`       |
+| supportsCredentials    | Sets the Access-Control-Allow-Credentials header.          | `false`       |
+
+The _allowedMethods_ and _allowedHeaders_ options are case-insensitive.
+
+You don't need to provide both _allowedOrigins_ and _allowedOriginsPatterns_. If one of the strings passed matches, it is considered a valid origin.
+
+If `array('*')` is provided to _allowedMethods_, _allowedOrigins_ or _allowedHeaders_ all methods / origins / headers are allowed.
+
+### Example: using the library
+
+```php
+<?php
+
+use Asm89\Stack\CorsService;
+
+$cors = new CorsService(array(
+    'allowedHeaders'         => array('x-allowed-header', 'x-other-allowed-header'),
+    'allowedMethods'         => array('DELETE', 'GET', 'POST', 'PUT'),
+    'allowedOrigins'         => array('localhost'),
+    'allowedOriginsPatterns' => array('/localhost:\d/'),
+    'exposedHeaders'         => false,
+    'maxAge'                 => false,
+    'supportsCredentials'    => false,
+));
+
+$cors->addActualRequestHeaders(Response $response, $origin);
+$cors->handlePreflightRequest(Request $request);
+$cors->isActualRequestAllowed(Request $request);
+$cors->isCorsRequest(Request $request);
+$cors->isPreflightRequest(Request $request);
+```
+
+## Example: using the stack middleware
+
+```php
+<?php
+
+use Asm89\Stack\Cors;
+
+$app = new Cors($app, array(
+    // you can use array('*') to allow any headers
+    'allowedHeaders'      => array('x-allowed-header', 'x-other-allowed-header'),
+    // you can use array('*') to allow any methods
+    'allowedMethods'      => array('DELETE', 'GET', 'POST', 'PUT'),
+    // you can use array('*') to allow requests from any origin
+    'allowedOrigins'      => array('localhost'),
+    // you can enter regexes that are matched to the origin request header
+    'allowedOriginsPatterns' => array('/localhost:\d/'),
+    'exposedHeaders'      => false,
+    'maxAge'              => false,
+    'supportsCredentials' => false,
+));
+```

+Introduction
+============
+
+The Doctrine Inflector has methods for inflecting text. The features include pluralization,
+singularization, converting between camelCase and under_score and capitalizing
+words.
+
+Installation
+============
+
+You can install the Inflector with composer:
+
+.. code-block:: console
+
+    $ composer require doctrine/inflector
+
+Usage
+=====
+
+Using the inflector is easy, you can create a new ``Doctrine\Inflector\Inflector`` instance by using
+the ``Doctrine\Inflector\InflectorFactory`` class:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+
+    $inflector = InflectorFactory::create()->build();
+
+By default it will create an English inflector. If you want to use another language, just pass the language
+you want to create an inflector for to the ``createForLanguage()`` method:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+    use Doctrine\Inflector\Language;
+
+    $inflector = InflectorFactory::createForLanguage(Language::SPANISH)->build();
+
+The supported languages are as follows:
+
+- ``Language::ENGLISH``
+- ``Language::FRENCH``
+- ``Language::NORWEGIAN_BOKMAL``
+- ``Language::PORTUGUESE``
+- ``Language::SPANISH``
+- ``Language::TURKISH``
+
+If you want to manually construct the inflector instead of using a factory, you can do so like this:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\CachedWordInflector;
+    use Doctrine\Inflector\RulesetInflector;
+    use Doctrine\Inflector\Rules\English;
+
+    $inflector = new Inflector(
+        new CachedWordInflector(new RulesetInflector(
+            English\Rules::getSingularRuleset()
+        )),
+        new CachedWordInflector(new RulesetInflector(
+            English\Rules::getPluralRuleset()
+        ))
+    );
+
+Adding Languages
+----------------
+
+If you are interested in adding support for your language, take a look at the other languages defined in the
+``Doctrine\Inflector\Rules`` namespace and the tests located in ``Doctrine\Tests\Inflector\Rules``. You can copy
+one of the languages and update the rules for your language.
+
+Once you have done this, send a pull request to the ``doctrine/inflector`` repository with the additions.
+
+Custom Setup
+============
+
+If you want to setup custom singular and plural rules, you can configure these in the factory:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+    use Doctrine\Inflector\Rules\Pattern;
+    use Doctrine\Inflector\Rules\Patterns;
+    use Doctrine\Inflector\Rules\Ruleset;
+    use Doctrine\Inflector\Rules\Substitution;
+    use Doctrine\Inflector\Rules\Substitutions;
+    use Doctrine\Inflector\Rules\Transformation;
+    use Doctrine\Inflector\Rules\Transformations;
+    use Doctrine\Inflector\Rules\Word;
+
+    $inflector = InflectorFactory::create()
+        ->withSingularRules(
+            new Ruleset(
+                new Transformations(
+                    new Transformation(new Pattern('/^(bil)er$/i'), '\1'),
+                    new Transformation(new Pattern('/^(inflec|contribu)tors$/i'), '\1ta')
+                ),
+                new Patterns(new Pattern('singulars')),
+                new Substitutions(new Substitution(new Word('spins'), new Word('spinor')))
+            )
+        )
+        ->withPluralRules(
+            new Ruleset(
+                new Transformations(
+                    new Transformation(new Pattern('^(bil)er$'), '\1'),
+                    new Transformation(new Pattern('^(inflec|contribu)tors$'), '\1ta')
+                ),
+                new Patterns(new Pattern('noflect'), new Pattern('abtuse')),
+                new Substitutions(
+                    new Substitution(new Word('amaze'), new Word('amazable')),
+                    new Substitution(new Word('phone'), new Word('phonezes'))
+                )
+            )
+        )
+        ->build();
+
+No operation inflector
+----------------------
+
+The ``Doctrine\Inflector\NoopWordInflector`` may be used to configure an inflector that doesn't perform any operation for
+pluralization and/or singularization. If will simply return the input as output.
+
+This is an implementation of the `Null Object design pattern <https://sourcemaking.com/design_patterns/null_object>`_.
+
+.. code-block:: php
+
+    use Doctrine\Inflector\Inflector;
+    use Doctrine\Inflector\NoopWordInflector;
+
+    $inflector = new Inflector(new NoopWordInflector(), new NoopWordInflector());
+
+Tableize
+========
+
+Converts ``ModelName`` to ``model_name``:
+
+.. code-block:: php
+
+    echo $inflector->tableize('ModelName'); // model_name
+
+Classify
+========
+
+Converts ``model_name`` to ``ModelName``:
+
+.. code-block:: php
+
+    echo $inflector->classify('model_name'); // ModelName
+
+Camelize
+========
+
+This method uses `Classify`_ and then converts the first character to lowercase:
+
+.. code-block:: php
+
+    echo $inflector->camelize('model_name'); // modelName
+
+Capitalize
+==========
+
+Takes a string and capitalizes all of the words, like PHP's built-in
+``ucwords`` function. This extends that behavior, however, by allowing the
+word delimiters to be configured, rather than only separating on
+whitespace.
+
+Here is an example:
+
+.. code-block:: php
+
+    $string = 'top-o-the-morning to all_of_you!';
+
+    echo $inflector->capitalize($string); // Top-O-The-Morning To All_of_you!
+
+    echo $inflector->capitalize($string, '-_ '); // Top-O-The-Morning To All_Of_You!
+
+Pluralize
+=========
+
+Returns a word in plural form.
+
+.. code-block:: php
+
+    echo $inflector->pluralize('browser'); // browsers
+
+Singularize
+===========
+
+Returns a word in singular form.
+
+.. code-block:: php
+
+    echo $inflector->singularize('browsers'); // browser
+
+Urlize
+======
+
+Generate a URL friendly string from a string of text:
+
+.. code-block:: php
+
+    echo $inflector->urlize('My first blog post'); // my-first-blog-post
+
+Unaccent
+========
+
+You can unaccent a string of text using the ``unaccent()`` method:
+
+.. code-block:: php
+
+    echo $inflector->unaccent('año'); // ano
+
+Legacy API
+==========
+
+The API present in Inflector 1.x is still available, but will be deprecated in a future release and dropped for 3.0.
+Support for languages other than English is available in the 2.0 API only.
+
