A Backbone.js demo app (Sinatra Backend)

Oct 16 2010

Updates

• 04/10/2011 - Updated application.js and application.rb thanks to @rebo's comments

In this article, I will walk through some simple steps to get a [demo app][2] up and running with [Backbone.js][3] and [Sinatra][4] on [Heroku][5].

@mixin gradient($from, $to) {
  /* fallback/image non-cover color */
  background-color: $from;

  /* Firefox 3.6+ */
  background-image: -moz-linear-gradient($from, $to);

  /* Safari 4+, Chrome 1+ */
  background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from($from), to($to));

Frustrating couple of hours banging my head against the GFM and Redcarpet pages before I saw Ryan's example:

    renderer = Redcarpet::Render::HTML.new(hard_wrap: false, filter_html: true)
    options = {
      autolink: true,
      no_intra_emphasis: true,
      fenced_code_blocks: true,
      lax_html_blocks: true,
 strikethrough: true,

    options = {

      no_intra_emphasis: true,
      fenced_code_blocks: true,
      lax_html_blocks: true,
      strikethrough: true,
      superscript: true
    }
    Redcarpet::Markdown.new(renderer, options).render(text).html_safe

namespace 'rails' do
  desc 'Renames the current app'
  task 'rename' do
    # Get the new name
    new_name = ENV["NEW_NAME"].capitalize || nil 
    if new_name.nil?
      puts "\nYou must pass in a new name"
      exit
    end
