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 GitHub Action.

That means you no longer search thru your GitHub Action 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 GitHub Action workflow:

Process a checkstyle formatted file

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

Available Options

• --graceful-warnings: Don't exit with error codes if there are only warnings
• --colorize: Colorize the output. Useful if the same lint script should be used locally on the command line and remote on GitHub Actions. With this option, errors and warnings are better distinguishable on the command line and the output is still compatible with GitHub Annotations

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

Phpstan 0.12.32 introduced native github actions support, therefore you might use this instead:

phpstan analyse

Using Psalm

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

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

psalm --output-format=github

Using PHP Coding Standards Fixer

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

Using PHP_CodeSniffer

phpcs --report=checkstyle -q /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
