Haml-rails provides Haml generators for Rails 4. It also enables Haml as the templating engine for you, so you don't have to screw around in your own application.rb when your Gemfile already clearly indicated what templating engine you have installed. Hurrah.
To use it, add this line to your Gemfile:
gem "haml-rails", "~> 0.9"
This ensures that:
- Any time you generate a resource, view, or mailer, you'll get Haml templates (instead of ERB)
- When your Rails application loads, Haml will be loaded and initialized automatically
- Haml templates will be respected by the view template cache digestor
Pretty fancy, eh? The modern world is just so amazing.
Once Haml-rails is installed on the Rails application,
you can convert the erb layout file, app/views/layouts/application.html.erb
to app/views/layouts/application.html.haml using this command:
$ rails generate haml:application_layout convert
After the application layout file is converted successfully,
make sure to delete app/views/layouts/application.html.erb, so Rails can
start using app/views/layouts/application.html.haml instead.
If you want to convert all of your .erb views into .haml, you can do so using the following command:
$ rake haml:erb2haml
If you already have .haml files for one or more of the .erb files, the rake task will give you the option of either replacing these .haml files or leaving them in place.
Once the task is complete, you will have the option of deleting the original .erb files. Unless you are under version control, it is recommended that you decline this option.
The current version of Haml-rails requires 4.0.1 or later.
Haml-rails version 0.4 is the last version to support Rails 3. To use it, add this line to your Gemfile:
gem "haml-rails", "~> 0.4.0"
