After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Libpsl binaries are bundled with the gem. The current version is checked out as a submodule in ./libpsl/. To update, checkout a later commit in the submodule (ideally matching an upstream release tag). You will then need to rebuild the binaries for all architectures. This requires running ./build-libpsl.sh in each environment. Depending on your setup, you may be able to accomplish that via virtual machines and/or Docker.

Check the comments in ./build-libpsl.sh for more information.

The submodule bump and updated binaries should be checked in to the repository.
