Prawndown! Super-tiny subset of Markdown for use with the Prawn PDF lib.

prawndown.coffee

class Prawndown
  constructor: (@text) ->
  
  toPrawn: ->
    @text.
      replace(/\n/g, "<br>\n").
      replace(/^# (.+)/gm, "<b>$1</b>")

# Use:
console.log (new Prawndown("# Foo\nbar")).toPrawn()

prawndown.rb

class Prawndown
  def initialize(text)
    @text = text
  end

  def to_prawn
    @text.to_s.gsub(/^# (.+)/, '<b>\1</b>')
  end
end


# Use in Prawn:
text = Prawndown.new("# Foo\nbar").to_prawn
pdf = Prawn::Document.new
pdf.text text, inline_format: true

Hi, I came across your gist.

I followed your sample code but when I run pdf.text text, inline_format: true it returns => nil
(the first 2 steps work great)

I saved prawndown.rb in my models and prawndown.coffee under assets/javascripts

Any idea?
