jonknapp / gist_tab.rb

Created September 19, 2014 18:39

I forked the original (https://gist.github.com/803483#file-gist_tag-rb) since I was having issues with Markdown / Jekyll trying to parse the <noscript> content and completely screwing it up. Removed the <noscript> tags and instead I hide the content with js once the page loads.

	require 'cgi'
	require 'digest/md5'
	require 'net/https'
	require 'uri'

	module Jekyll
	class GistTag < Liquid::Tag
	def initialize(tag_name, text, token)
	super
	@text = text
