Give rails the power to render code samples in rouge colored glory.

Add this line to your application's Gemfile:

gem 'rouge-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rouge-rails

Stylesheets with standard colorschemes are available in the asset pipeline. Include them in your applications application.scss

@import "rouge";

1. Place the code sample in a partial somewhere in your views directory and use ".rouge" as the file extension, e.g.:

# app/views/home/_code_sample.rouge
class MyCode
  def example
    puts "hello world"
  end
end

2. Render the code sample in your view:

# app/views/home/index.html.erb
<%= render "code_sample", language: :ruby %>

Add this code to an initializer in your app

# config/initializers/rouge.rb
Rouge::Rails.configure do |config|
  config.default_colorscheme = "solarized-dark"
end

<%= render "code_sample", language: :ruby, colorscheme: "github" %>

# app/controllers/home_controller.rb
def index
  @greeting = "hello world"
end
# app/views/home/_code_sample.rouge
class MyCode
  def example
    puts "<%= @greeting %>"
  end
end

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