PHP Semantic Versioning Checker

PHP Semantic Versioning Checker is a console/library which allows you to inspect a set of before and after source code.

After the inspection is completed, you are given a list of changes that have occurred between the two changesets following Semantic Versioning 2.0.0. For each of these changes, the level of the change (MAJOR, MINOR, PATCH) will be given, as well as the location of the change (file and line number) and a reason as to why this level change is suggested.

Semantic Versioning 2.0.0 Overview

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes,
• MINOR version when you add functionality in a backwards-compatible manner, and
• PATCH version when you make backwards-compatible bug fixes.

Getting started

As this is still an alpha package, it is not suggested to include php-semver-checker directly in your composer.json. There are however a couple ways to use the tool:

1. Preferred method Download the latest .phar build. Note that the .phar build is generally less bleeding edge than the following methods.
2. php composer.phar create-project tomzx/php-semver-checker --stability=dev will clone to a new php-semver-checker folder in your current working directory
3. git clone https://github.com/tomzx/php-semver-checker.git and php composer.phar install in the newly cloned directory.

See the example section for examples of how to use the tool.

Building php-semver-checker.phar

First, make sure you have box installed. Then, in the base directory, you can run the following command which will generate the php-semver-checker.phar file.

box build

Current ruleset & verification codes

See docs/Ruleset.md for an exhaustive list of currently supported (and to come) ruleset.

Verification codes are a mean to uniquely identify a semantic versioning trigger (a condition which upon detection, requires your code changes to be versioned).

Example

php bin/php-semver-checker compare tests/fixtures/before tests/fixtures/after
