Running ESLint on commit for mozilla-central (Git & Mercurial)

A while ago, Dave Townsend wrote a commit hook for Mercurial for ESLint. I’ve just extended the code to create a commit hook for Git users.

To install the Git hook, go into the top-level of your mozilla-central Git repository, and enter (assuming you don’t already have a pre-commit hook):

ln -s ../../tools/git/ .git/hooks/pre-commit

That’s all you need to do. If you do have an existing pre-commit hook, then you’ll need to incorporate running as well.

This will run ESLint on the affected files when committing and print warnings if they fail. The commit will still happen, but you should fix the issues up before pushing them for review.

WebExtensions: An Example Add-on Repository with Test Harnesses

I’ve created an example repository for how you might set up tools to help development of a WebExtension. Whilst there are others around, I’ve not heard of one that includes examples of tools for testing and auditing your extension.

It is based on various ideas from projects I’ve been working alongside recently.

The repository is intended to either be used as a starting point for constructing a new WebExtension, or you can take the various components and integrate them into your own repository.

It is based around node/npm and the web-ext command line tool to keep it simple as possible. In addition it contains setup for:

All of these are also run automatically on landing or pull request via Travis Ci with Coveralls providing code coverage reports.

Finally, there’s a tool enabled on the repository for helping to keep modules up to date.

If you find it helpful, let me know in the comment section. Please raise any issues that you find, or submit pull requests, I welcome either.
