Composer - Package Management for PHP ===================================== Composer is a package manager tracking local dependencies of your projects and libraries. See the [about page](http://packagist.org/about) on [packagist.org](http://packagist.org/) for more information. [![Build Status](https://secure.travis-ci.org/composer/composer.png)](http://travis-ci.org/composer/composer) Installation / Usage -------------------- 1. Download the [`composer.phar`](http://getcomposer.org/composer.phar) executable 2. Create a composer.json defining your dependencies. Note that this example is a short version for applications that are not meant to be published as packages themselves. To create libraries/packages please read the [guidelines](http://packagist.org/about). ``` json { "require": { "monolog/monolog": ">=1.0.0" } } ``` 3. Run Composer: `php composer.phar install` 4. Browse for more packages on [Packagist](http://packagist.org). Installation from Source ------------------------ To run tests, or develop Composer itself, you must use the sources and not the phar file as described above. 1. Run `git clone https://github.com/composer/composer.git` 2. Download the [`composer.phar`](http://getcomposer.org/composer.phar) executable 3. Run Composer to get the dependencies: `php composer.phar install` Global installation of composer ------------------------------- Since composer works with the current working directory it is possible to install it in a system wide way. 1. Change into a directory in your path like `cd /usr/local/bin` 2. Get composer `wget http://getcomposer.org/composer.phar` 3. Make the phar executeable `chmod a+x composer.phar` 3. Change into a project directory `cd /path/to/my/project` 4. Use composer as you normally would `composer.phar install` Configuration ------------- Additional options for composer can be configured in `composer.json` by using the `config` section. ``` json { "config": { "vendor-dir": "custom/path/for/vendor" } } ``` * `vendor-dir`: The location to install vendor packages. The location can be supplied as an absolute or relative path but **must** be within the current working directory. Contributing ------------ All code contributions - including those of people having commit access - must go through a pull request and approved by a core developer before being merged. This is to ensure proper review of all the code. Fork the project, create a feature branch, and send us a pull request. Requirements ------------ PHP 5.3+ Authors ------- Nils Adermann - - -
