## Contributing

I value any contribution to Diff::LCS you can provide: a bug report, a feature
request, or code contributions. Code contributions to Diff::LCS are especially
<del>welcome</del>encouraged. Because Diff::LCS is a complex codebase, there
are a few guidelines:

*   Code changes *will not* be accepted without tests. The test suite is
    written with [RSpec][].
*   Match my coding style.
*   Use a thoughtfully-named topic branch that contains your change. Rebase
    your commits into logical chunks as necessary.
*   Use [quality commit messages][].
*   Do not change the version number; when your patch is accepted and a release
    is made, the version will be updated at that point.
*   Submit a GitHub pull request with your changes.
*   New or changed behaviours require appropriate documentation.

### Test Dependencies

Diff::LCS uses Ryan Davis’s [Hoe][] to manage the release process, and it adds
a number of rake tasks. You will mostly be interested in:

    $ rake

which runs the tests the same way that:

    $ rake spec
    $ rake travis

will do.

To assist with the installation of the development dependencies, I have
provided a Gemfile pointing to the (generated) `diff-lcs.gemspec` file. This
will permit you to do:

    $ bundle install

to get the development dependencies. If you aleady have `hoe` installed, you
can accomplish the same thing with:

    $ rake newb

This task will install any missing dependencies, run the tests/specs, and
generate the RDoc.

You can run tests with code coverage analysis by running:

    $ rake spec:coverage

### Workflow

Here's the most direct way to get your work merged into the project:

*   Fork the project.
*   Clone down your fork (`git clone git://github.com/<username>/diff-lcs.git`).
*   Create a topic branch to contain your change (`git checkout -b
    my_awesome_feature`).
*   Hack away, add tests. Not necessarily in that order.
*   Make sure everything still passes by running `rake`.
*   If necessary, rebase your commits into logical chunks, without errors.
*   Push the branch up (`git push origin my_awesome_feature`).
*   Create a pull request against halostatue/diff-lcs and describe what your
    change does and the why you think it should be merged.
