= Brightly Easily add code a syntax highlighting system to Markdown to make your site's markdown a little more useful. == Point? There is a wonderful gem that lets you syntax highlight based on TextMate sytle's (Ultraviolet). There's only one problem. The dependencies required to use it don't exist on Heroku. Aww no Heroku love? No. Just wrap you Markdown requests into a simple REST call to this little service and your set. == Server Setup You'll need Onigurma to use ultraviolet which is used do do the highlighting in Brightly (hence the whole reason for the service). Website: http://www.geocities.jp/kosako3/oniguruma/ OS X Installation (from source): curl -O http://www.geocities.jp/kosako3/oniguruma/archive/onig-5.9.1.tar.gz tar xvf onig-5.9.1.tar.gz cd onig-5.9.1 ./configure make sudo make install OS X Installation (from ports): sudo port install oniguruma Ubuntu Installation: sudo aptitude install libonig-dev sudo gem install oniguruma Brightly: sudo gem install brightly --source=http://gemcutter.org For development you can easily run brightly via the command line: brightly Will start a Sinatra server going. To get things running with a webserver (passenger + apache, etc) using rack set your config up like: config.ru: begin require 'brightly' rescue require 'rubygems' require 'brightly' end run Brightly::Provider::Base == Client Usage config/environment.rb: gem.config :lib => false, :version => '>=0.1.0', :source => "http://gemcutter.org" config/initializers/brightly.rb: Brightly::Consumer.provider_url = "http://your-host.com" Brightly::Consumer.theme = "blackboard" In your controller or model: brighten("# Some Markdown") Remember that you likely don't want to do this every hit to a page, markdown processing is done with RDiscount so it's fast, but code highlighting and markdown processing and the service call all adds up. Store the result, get better performance. Cheers! == And in you Markdown Here's some ruby: <code language="ruby"> def candy puts "is sweet!" end </code> == Things of Interest Making this I stumbled upon an interesting Rack Middleware which also does syntax highlighting. If you don't need to make the call to a service, it might be of use you you. Check it out: http://coderack.org/users/wbzyl/entries/19-rackcodehighlighter == Copyright Copyright (c) 2009 Adam Elliot.
