# Opal Haml

*Haml templates for Opal*

[![Build Status](https://travis-ci.org/opal/opal-haml.svg?branch=master)](https://travis-ci.org/opal/opal-haml)

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:

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

## Usage

Add opal-haml to your `Gemfile`:

```ruby
gem 'opal-haml'
```

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

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

Render the haml template:

```ruby
# 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>
```

## Running tests

Get dependencies:

```
$ bundle install
```

Run tests using opal-rspec:

```
$ bundle exec rake
```

Run specs in the browser:
