Version

Version is a library that helps with managing the version number of Git-hosted PHP projects.

Installation

Composer

Simply add a dependency on sebastian/version to your project's composer.json file if you use Composer to manage the dependencies of your project.

PEAR Installer

The following two commands (which you may have to run as root) are all that is required to install Version using the PEAR Installer:

pear config-set auto_discover 1
pear install pear.phpunit.de/Version

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.
