TunaRoll

Find all the HTML classes used in your templates. Super-duper experimental, only works on Slim and ERB (although any Temple engine can be adapted), and only find classes statically in the templates themselves.

It works by rendering the template without any Ruby code (so it renders every possible branch) and just extracts all the class attributes. Yeah I know it's really dumb, but anything smarter would be a ridiculous amount of effort.

If it detects any classes with a dynamic portion, it just replaces that portion with the string %DYNAMIC%.

Install the gem and add to the application's Gemfile by executing:

bundle add tuna_roll

If bundler is not being used to manage dependencies, install the gem by executing:

gem install tuna_roll

$ tunarall app/views/**/*.erb

Outputs all the classes to stdout. Can take a few seconds if your app is large.

Internally it's just calling TunaRoll::ClassUnroller.new(path).call on every file.

Because it unrolls templates into flat HTML to get all the classes, so template-unroll -> tunroll -> TunaRoll.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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 the created tag, and push the .gem file to rubygems.org.
