  • What was the expected result?

Pull requests

Bug fixes and general improvements to the existing codebase are always welcome. New features are also welcome, but will be judged on an individual basis. If you'd rather not risk wasting your time implementing a new feature only to see it turned down, please start the discussion by opening an issue.

Don't forget to add your changes to the changelog.


Please include tests for every change or addition to the code. To run the complete test suite:


When submitting a new pull request, please make sure that that the test suite passes (Travis CI will run it & report back on your pull request.)

To run the tests on Windows, run tests/ from the command line in order to convert Linux-style test symlinks to Windows-style.

Coding standards

All code must follow PSR-2. Just make sure to run php-cs-fixer before submitting the code, it'll take care of the formatting for you:

vendor/bin/php-cs-fixer fix src
vendor/bin/php-cs-fixer fix tests

Document the code thoroughly!


Note that minify is MIT-licensed, which basically allows anyone to do anything they like with it, without restriction.
