PHP Semantic Versioning Checker for git

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

The command line utility will use an existing git repository to compare to changesets using anything git checkout would accept (sha1, branch, tag). It will checkout in detached mode in order not to pollute your list of branches.

Note It is strongly suggested you do not run this directly on any repository you do not want to lose. Make a copy of it beforehand and run php-semver-checker-git on that copy instead.

Getting started

As this is still an alpha package, it is not suggested to include php-semver-checker-git 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-git --stability=dev will clone to a new php-semver-checker-git folder in your current working directory
3. git clone https://github.com/tomzx/php-semver-checker-git.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-git.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-git.phar file.

box build

Using php-semver-checker-git with GitHub actions

It is very easy to add php-semver-checker-git to your build process and to get a nice report you can check in the GitHub actions logs. In a file under .github/workflows/, add the following:

name: Continuous integration

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    
    steps:
    - name: Checkout code
      uses: actions/checkout@v2
      with:
        fetch-depth: 0

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
          php-version: ${{ matrix.php }}
          tools: composer:v2
          coverage: xdebug

    # Your own CI configuration goes here

    - name: Evaluate semantic versioning
      run: |
        wget https://psvcg.coreteks.org/php-semver-checker-git.phar
        php php-semver-checker-git.phar suggest -vvv --include-before=src --include-after=src --details --allow-detached

In order to simplify the above call to php-semver-checker-git, we suggest you create a php-semver-checker-git.yml configuration file at the root of your project. In it, you can put the following:

allow-detached: true
details: true
include-before: src
include-after: src

With this configuration file, you can update the configuration file created previously:

Before:

  # Your own CI configuration goes here

    - name: Evaluate semantic versioning
      run: |
        wget https://psvcg.coreteks.org/php-semver-checker-git.phar
        php php-semver-checker-git.phar suggest -vvv --include-before=src --include-after=src --details --allow-detached

After:

  # Your own CI configuration goes here

    - name: Evaluate semantic versioning
      run: |
        wget https://psvcg.coreteks.org/php-semver-checker-git.phar
        php php-semver-checker-git.phar suggest -vvv

Example

Compare two commits (without semantic versioning)

# arguments are: before-commit/branch/tag after-commit/branch/tag
php bin/php-semver-checker-git compare v1.6.4 v2.0.0 --include-before=src --include-after=src

Compare HEAD against your latest semantic version tag

php bin/php-semver-checker-git suggest --allow-detached --include-before=src --include-after=src

Note: --allow-detached is very useful when you are running this command on GitHub actions or any other continuous integration provider. It is necessary when a checkout is done on a particular commit, which makes HEAD become detached. If this option is not passed to the command, it will abort. This is done because it is impossible to revert the original detached branch when the suggest command completes.

Compare HEAD against a specific tag constraint

php bin/php-semver-checker-git suggest --allow-detached --include-before=src --include-after=src  --tag=~5.0

Note: --tag supports any semantic versioning constraint such as <, <=, >=, '>', ~x.y.z, ^x.y.z x.y.*.
