Share Code Snippets in Blogger

Hi folks,
From time to time, I wanted to share code snippets in Blogger which is pretty crappy for said task...
until... I found out about gists from github...

Gists are a great way to share code snippets. You can create them on github, and just like all code repos, they are versioned and backed up...

You can make your code look as pretty as this:

and this:

	require 'nokogiri'
	require 'open-uri'
	require 'net/http'
	require 'cgi'
	class Snippet < ActiveRecord::Base
	before_save :send_to_gist
	def gist_url
	"http://gist.github.com/#{self.gist_id}"
	end
	def gist_url=(url)
	id = url.match(/[http:\/\/gist.github.com\/]?(\d+)\/?/)
	unless id.nil?
	p id[1]
	self.gist_id = id[1]
	gist_url = "http://gist.github.com/#{gist_id}"
	doc = Nokogiri::HTML.parse(open(gist_url))
	raw_gist_url = "http://gist.github.com" + doc.xpath('//a[text()="raw"]').first.attributes['href'].to_s
	self.code = open(raw_gist_url).read
	end
	end
	def send_to_gist
	if self.gist_id.blank?
	response = Net::HTTP.post_form(URI.parse('http://gist.github.com/api/v1/xml/new'), { "files[#{title.downcase.gsub(' ', '_')}.rb]" => "#{code}" })
	doc = Nokogiri::XML.parse(response.body)
	repo_id = doc.xpath('//repo').first.content
	write_attribute(:gist_id, repo_id)
	end
	end
	end

	@snippet.gist_url = 12345
