I am using rails and redcloth, I have the plain-text in the database, 
and the text gets parsed when the view gets called atm.

I am using Uv to for the syntax, which I pull out before sending to 
redcloth
[code]
def snatch_code(text)
    snippets = text.scan(/#>code\((\S+)\)(.+?)#>code/m)

    snippets.each do |snip|
      code = Uv.parse(snip[1], 'xhtml', snip[0], false, 'twilight')
      code.insert(0, "<notextile>")
      code.insert(code.length, "</notextile>")
      text.sub!(/#>code\((\S+)\)(.+?)#>code/m, code)
    end

    text
  end
[/code]
then redcloth parses it.

dyslexia rules! KO!

I want to stop the escaping that’s not dealing with whitespace, tab, new 
line etc.
