Tired of building custom navigation code for each site?

Have you seen Ryan Heath's Navigation Helper? It's very usable, but it only does one nav-bar. I often have sites where there are many, e.g.

+-----------------------------------------------------------+
| MyApp                           | Home | Sign Out | FAQ | | # "site" nav bar
|===========================================================|
| | *Projects* | Friends |                                  | # "area" nav bar
|===========================================================|

| | Project Overview | Budget | History | | # "tabs" nav bar

# Create a file `spec/acceptance/support/warden.rb' with the following 
# contents:

Spec::Runner.configure do |config|
  config.include Warden::Test::Helpers, :type => :acceptance
  config.after(:each, :type => :acceptance) { Warden.test_reset! }
end

# Or, if you're using RSpec 2 / Rails 3, the contents should be the following 
# instead:

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

describe "GET current" do
    before do
      @request.cookies['hidden_notices'] = "1,#{notices(:permanent).id}"
      get :current, :format => 'js'
    end

    it { should respond_with(:success) }
    it { should set_cookie(:hidden_notices).to("#{notices(:permanent).id}") }
    it { should render_template('notices/current') }
  end

# change 'table' to a more specific selector when the page will have more than one table

find('table').all('tr').map { |row| row.all('th, td').map { |cell| cell.text.strip } }
