Parsing changelogs made simple

Changelog parser

Requirements

• php 7.1 or greater (supported versions)

Why

A changelog contains information about all the changes in a project. This parsers can be used to extract information about a specific release. That information may then be distributed towards your friends, clients, colleagues and other parties.

Installation

composer require tfarla/changelog-parser

Usage

Given we have the following markdown file:

## 1.0.0 - 2018-12-20
### Added
- A cool new feature

### Changed
- that thing that was too complex
- slow code into fast code

### Removed
- A gastly bug

When we parse that markdown file using the MarkdownParser:

<?php

use \TFarla\ChangelogParser\MarkdownParser;

$parser = new MarkdownParser();

$result = $parser->parse(file_get_contents('CHANGELOG.md'));

foreach ($result->getReleases() as $release) {
    echo $release->getVersion() . PHP_EOL;
    echo $release->getDate()->format('Y-m-d') . PHP_EOL;
    foreach ($release->getChanges() as $type => $changes) {
        echo $type . PHP_EOL;
        foreach ($changes as $change) {
            echo "- $change" . PHP_EOL;
        }
    }
}

Then we will receive the following output:

1.0.0
2018-12-20
Added
- A cool new feature
Changed
- that thing that was too complex
- slow code into fast code
Removed
- A gastly bug

Tested changelog formats can be found under the tests/fixtures directory.

Running tests
