Submitting an Issue

We use the GitHub issue tracker to track bugs and features. Before submitting a bug report or feature request, check to make sure it hasn't already been submitted. You can indicate support for an existing issue by voting it up. When submitting a bug report, please include a Gist that includes a stack trace and any details that may be necessary to reproduce the bug, including your gem version, Ruby version, and operating system. Ideally, a bug report should include a pull request with failing specs.

Submitting a Pull Request

1. Fork the project.
2. Create a topic branch.
3. Implement your feature or bug fix.
4. Add documentation for your feature or bug fix.
5. Run bundle exec rake doc:yard. If your changes are not 100% documented, go back to step 4.
6. Add specs for your feature or bug fix.
7. Run bundle exec rake spec. If your changes are not 100% covered, go back to step 6.
8. Commit and push your changes.
9. Submit a pull request. Please do not include changes to the gemspec, version, or history file. (If you want to create your own version for some reason, please do so in a separate commit.)

Supported Ruby Versions

This library aims to support and is tested against the following Ruby implementations:

• Ruby 1.8.7
• Ruby 1.9.2
• Ruby 1.9.3
• JRuby
• Rubinius
• Ruby Enterprise Edition

If something doesn't work on one of these interpreters, it should be considered a bug.

This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be personally responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
