Rakefile for Jekyll with draft & publish management

Rakefile

require 'date'

desc "Given a title as an argument, create a new post file"
task :draft, :title do |t, args|
    puts "Creating _drafts/#{args.title}"
    filename = "#{args.title.gsub(/\s/, '_').downcase}.markdown"
    path = File.join("_drafts", filename)
    if File.exist? path; raise RuntimeError.new("Won't clobber #{path}"); end
    File.open(path, 'w') do |file|
        file.write <<-EOS
---
layout: post
title: #{args.title}
---
Content goes here
EOS
    end
    puts "Now open #{path} in an editor."
end


desc "Given a draft path as an argument, move it to '_posts' to publish it"
task :publish, :srcPath do |t, args|
    now = DateTime::now().to_date()
    filename = "#{now.strftime}-#{File.basename(args.srcPath)}"
    destPath = File.join("_posts", filename)
    if File.exist? destPath; raise RuntimeError.new("Won't clobber #{destPath}"); end
    FileUtils.mv(args.srcPath, destPath)
end

Inspired by http://ilkka.github.com/blog/2010/12/08/rakefile_for_jekyll_site_management/
To use it, just put it in the root folder of your jekyll site, and call it via bash :
rake draft["Document title"]
rage publish["draft_path"]

The drafts will be created in the _drafts folder, be sure to create it before calling the Rakefile.
