Redcarpet and coderay- regular expression help

dummy@example.com (tuscanidream) — Sat, 28 Jan 2012 17:23:59 +0000

I am trying to use redcarpet and code ray together. I was followed Railscasts #272 Markdown with Redcarpet. However, I do not want to use Pygments for syntax highlighting due to issues with heroku. A gem solution would be much better, so I followed Railscasts #207 Syntax Highlighting to implement coderay.

Here is the helper method provided for coderay:

module ApplicationHelper  
  def coderay(text)
    text.gsub(/\(.+?)\<\/code\>/m) do
      CodeRay.scan($3, $2).div(:css => :class)
    end
  end
end

I am trying to make code blocks use the github style syntax of ``` ruby or ```ruby.

I've been using rubular to try to create a regular expression to match ^^^^. Here is what I have so far, but it does not work. Please help me out! Thank you!

# regex to match
/`{3}\s?(.*)\n(.*)`{3}/

# test strings
``` ruby
def rubyroo
```

```ruby
def rubyroo
```
