opal-haml: Haml templates for opal

Build Status

This gem adds .haml files to sprockets to precompile templates for opal. This gem does not make the haml compiler available under opal, just the result of pre-compiling a haml template.

A small runtime is included to handle dynamic attributes, as well as allowing content to be rendered.

All haml templates become available under the Template constant in Opal, which allows a template to be easily rendered in a context:

Template['user'].render(my_user)
# => <div>..</div>

Usage

Add opal-haml to your Gemfile:

gem 'opal-haml'

Create a haml file in the opal load path (e.g. app/user_template.haml):

.row
  .col-md-6
    = self.name
  .col-md-6
    = self.age

Render the haml template:

# app/application.rb
require 'user_template'

class User
  attr_accessor :name, :age

  def initialize(name, age)
    @name, @age = name, age
  end
end

user = User.new('Ford Prefect', 42)
html = Template['user_template'].render(user)
puts html
# => <div class="row">...</div>
