Version

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

Installation

You can add this library as a local, per-project dependency to your project using Composer:

composer require sebastian/version

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/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`.
