Sinatra::Glorify

Sinatra helper to parse markdown with syntax highlighting like the pros

Renders markdown via rdoc-rouge, an RDoc and Rouge bridge.

Able to use fenced code blocks like github, and includes a default pygments stylesheet.

Requirements

Ruby 1.9.2 or greater, also supports JRuby and Rubinius when using 1.9 modes.

Installation

gem install glorify

or with bundler

# Gemfile
source :rubygems
gem 'sinatra'
gem 'glorify'

Sinatra::Glorify::Template

Sinatra::Glorify comes with a tilt template for rendering markdown.

This allows you to override the default markdown renderer and use rdoc-rouge to highlight any code blocks within your view.

In order to do this, you will need to prefer the template class.

Tilt.prefer Sinatra::Glorify::Template

Now, any views that render via markdown will use Sinatra::Glorify::Template instead.

register Sinatra::Glorify
get '/' do
  markdown :a_view_with_code_blocks
end

Sinatra::Glorify::Helpers

If you want to stick with your current renderer and just render some code blocks within your view, use the Sinatra::Glorify::Helpers#glorify helper method.

Depending on the type of application you're building with Sinatra, the manner in which Sinatra::Glorify is used will change.

See the Sinatra documentation on Modular vs. Classic style

With a classical app

Simply require 'glorify' to use the helper with a classic style sinatra app.

require 'sinatra'
require 'glorify'
require 'erb'
get '/' do
  @example = File.open("#{File.dirname(__FILE__)}/example.md", "rb").read
  erb :index
end

With a modular app

You will need to register Sinatra::Glorify in your sub-classed app, along with require 'glorify', to use with a modular style sinatra app.

require 'sinatra/base'
require 'glorify'
require 'erb'
class SubclassedApp < Sinatra::Base
  register Sinatra::Glorify
  get '/' do
    @example = File.open("#{File.dirname(__FILE__)}/example.md", "rb").read
    erb :index
  end
end

The view

This is just a simple erb template, but you get the idea.

<html>
  <head>
    <link rel="stylesheet" type="text/css" href="/pygments.css" />
  </head>
  <body>
    <%= glorify @example %>
  </body>
</html>

The default pygments stylesheet that comes with glorify is available at the /pygments.css route.

Still stuck?

The Sinatra documentation on extensions does a great job of explaining how to use and implement extensions using the Sinatra API.
