Grease

Grease provides an adapter to use Tilt as extension of Sprockets 3 or later.

Add this line to your application's Gemfile:

gem "grease"

And then execute:

$ bundle

Or install it yourself as:

$ gem install grease

When you'd like to use Tilt::HamlTemplate in Sprockets, add code like this:

# Sprockets 3
register_engine ".haml", Grease.apply(Tilt::HamlTemplate), mime_type: Tilt::HamlTemplate.default_mime_type, silence_deprecation: true

# Sprockets 4 or later
register_mime_type "text/haml", extensions: %w(.haml .html.haml)
register_transformer "text/haml", Tilt::HamlTemplate.default_mime_type, Grease.apply(Tilt::HamlTemplate)

It works because Grease.apply returns a "callable" object.

You should follow the steps below.

1. Fork the repository
2. Create a feature branch: git checkout -b add-new-feature
3. Commit your changes: git commit -am 'add new feature'
4. Push the branch: git push origin add-new-feature
5. Send us a pull request

We use Appraisal to test with different versions of Sprockets.

bundle install
appraisal install

# Run rspec with a specific version of Sprockets
appraisal sprockets4 rspec

# Run rspec with all versions of Sprockets
appraisal rspec
