Contribute

You are welcome to contribute code using GitHub pull requests. Unless your contribution is really trivial you should get in touch with me first (preferably by creating a new issue on the issue tracker) - this can prevent wasted effort on both sides.

Before submitting a pull request, please make sure you've checked out the Contribution Guidelines.

Ensure you have Node.js v6+ and Yarn installed.

1. Create a fork of https://github.com/pegjs/pegjs
2. Clone your fork, and optionally create a new branch
3. Run the command yarn install from the root of your clone
4. Add and commit your changes
5. Validate your changes:
   • Lint the JavaScript changes (command line only, run yarn lint)
   • Run tests to ensure nothing's broken: yarn test from the root of the repository
   • Run benchmarks to check performance: yarn benchmark
   • Check the impact of your commits: see separate documentation
6. If validation fails: reverse your commit, fix the problem and then add/commit again
7. Push the commits from your clone to the fork
8. From your fork, start a new pull request

It's also a good idea to check out the package.json that defines various scripts.
