Contributing

We accept contributions via Pull Requests on Github.

Pull Requests

Code must follow PSR-1, PSR-2 Coding Standards - The easiest way to apply the conventions is to install PHP Code Sniffer and run it.
Add tests! - Your patch won't be accepted if it doesn't have tests. Run PHPUnit to make sure, that all tests pass.
Document any change in behaviour - Make sure the README.md and any other relevant documentation are kept up-to-date.
Consider our release cycle - We try to follow SemVer v2.0.0. Randomly breaking public APIs is not an option. Update CHANGES.md accordingly.
One pull request per feature - If you want to do more than one thing, send multiple pull requests.

If you have GNU Make installed, you can use following shortcuts:

make cs (instead of php vendor/bin/phpcs) - run static code analysis with PHP_CodeSniffer to check code style
make csfix (instead of php vendor/bin/phpcbf) - fix code style violations with PHP_CodeSniffer automatically, where possible (ex. PSR-2 code formatting violations)
make test (instead of php vendor/bin/phpunit) - run tests with PHPUnit
make install - instead of composer install
make all or just make without parameters - invokes described above install, cs, test tasks sequentially - project will be assembled, checked with linter and tested with one single command

$ make test

or

$ composer test

Happy coding!
