| # Version
 | |
| 
 | |
| **Version** is a library that helps with managing the version number of Git-hosted PHP projects.
 | |
| 
 | |
| ## Installation
 | |
| 
 | |
| Simply add a dependency on `sebastian/version` to your project's `composer.json` file if you use [Composer](http://getcomposer.org/) to manage the dependencies of your project.
 | |
| 
 | |
| ## Usage
 | |
| 
 | |
| The constructor of the `SebastianBergmann\Version` class expects two parameters:
 | |
| 
 | |
| * `$release` is the version number of the latest release (`X.Y.Z`, for instance) or the name of the release series (`X.Y`) when no release has been made from that branch / for that release series yet.
 | |
| * `$path` is the path to the directory (or a subdirectory thereof) where the sourcecode of the project can be found. Simply passing `__DIR__` here usually suffices.
 | |
| 
 | |
| Apart from the constructor, the `SebastianBergmann\Version` class has a single public method: `getVersion()`.
 | |
| 
 | |
| Here is a contrived example that shows the basic usage:
 | |
| 
 | |
|     <?php
 | |
|     $version = new SebastianBergmann\Version(
 | |
|       '3.7.10', '/usr/local/src/phpunit'
 | |
|     );
 | |
| 
 | |
|     var_dump($version->getVersion());
 | |
|     ?>
 | |
| 
 | |
|     string(18) "3.7.10-17-g00f3408"
 | |
| 
 | |
| When a new release is prepared, the string that is passed to the constructor as the first argument needs to be updated.
 | |
| 
 | |
| ### How SebastianBergmann\Version::getVersion() works
 | |
| 
 | |
| * If `$path` is not (part of) a Git repository and `$release` is in `X.Y.Z` format then `$release` is returned as-is.
 | |
| * If `$path` is not (part of) a Git repository and `$release` is in `X.Y` format then `$release` is returned suffixed with `-dev`.
 | |
| * If `$path` is (part of) a Git repository and `$release` is in `X.Y.Z` format then the output of `git describe --tags` is returned as-is.
 | |
| * If `$path` is (part of) a Git repository and `$release` is in `X.Y` format then a string is returned that begins with `X.Y` and ends with information from `git describe --tags`.
