Annotate a Pull Request based on a Checkstyle XML-report

Turns checkstyle based XML-Reports into Github Pull Request Annotations via the Checks API. This script is meant for use within your GithubAction.

That means you no longer search thru your GithubAction logfiles. No need to interpret messages which are formatted differently with every tool. Instead you can focus on your Pull Request, and you don't need to leave the Pull Request area.

Installation

Install the binary via composer

composer require staabm/annotate-pull-request-from-checkstyle

Example Usage

cs2pr can be used on a already existing checkstyle-report xml-file. Alternatively you might use it in the unix-pipe notation to chain it into your existing cli command.

Run one of the following commands within your GithubAction workflow:

Process a checkstyle formatted file

vendor/bin/cs2pr /path/to/checkstyle-report.xml

Pipe the output of another commmand

... works for any command which produces a checkstyle-formatted report.

Examples can bee seen below:

Using PHPStan

phpstan analyse --error-format=checkstyle | vendor/bin/cs2pr

Using Psalm

psalm --output-format=checkstyle | vendor/bin/cs2pr

Psalm even supports the required format natively, therefore you might even use this instead:

psalm --output-format=github

Using PHP Coding Standards Fixer

php-cs-fixer --format=checkstyle | vendor/bin/cs2pr

Using PHP_CodeSniffer

phpcs --report=checkstyle /path/to/code | vendor/bin/cs2pr

phpunit support?

PHPUnit does not support checkstyle, therefore cs2pr will not work for you.

you might instead try

• a phpunit problem matcher
• a phpunit-github-actions-printer

Example GithubAction workflow

If you're using shivammathur/setup-php to setup PHP, cs2pr binary is shipped within:

# ...
jobs:
    phpstan-analysis:
      name: phpstan static code analysis
      runs-on: ubuntu-latest
      steps:
          - uses: actions/checkout@v2
          - name: Setup PHP
            uses: shivammathur/setup-php@v1
            with:
                php-version: 7.3
                coverage: none # disable xdebug, pcov
                tools: cs2pr
          - run: |
                composer install # install your apps dependencies
                vendor/bin/phpstan analyse --error-format=checkstyle | cs2pr

If you use a custom PHP installation, then your project needs to require staabm/annotate-pull-request-from-checkstyle

# ...
jobs:
    phpstan-analysis:
      name: phpstan static code analysis
      runs-on: ubuntu-latest
      steps:
          - uses: actions/checkout@v2
          - name: Setup PHP
            run: # custom PHP installation 
          - run: |
                composer install # install your apps dependencies
                composer require staabm/annotate-pull-request-from-checkstyle # install cs2pr
                vendor/bin/phpstan analyse --error-format=checkstyle | vendor/bin/cs2pr
