Quick and dirty ruby script to parse a copy/pasted list of GitHub Issues and output a nicely formatted markdown list that can be pasted into a blog post

github_issues_to_markdown.rb

#!/usr/bin/env ruby

require 'optparse'

USAGE = "usage: #{$0} [options] GITHUB_REPO_URL [FILE]"

optparser = OptionParser.new do |opts|
  opts.banner = USAGE

  opts.separator ''
  opts.separator 'Options:'

  opts.on('-h','--help','Print this cruft') do
    puts opts
    exit
  end

  opts.separator ''
  opts.separator 'Arguments:'
  opts.separator "\tGITHUB_REPO_URL\t\tThe URL to the github.com repo"
  opts.separator "\tFILE\t\t\tOptional file to parse. Defaults to parsing STDIN"
  opts.separator ''
  opts.separator 'Parses a list of GitHub Issues and outputs a markdown list'
end

optparser.parse!(ARGV)

if ARGV.length == 0
  $stderr.puts(USAGE)
  exit -1
end

github_repo_url  = ARGV[0].chomp('/') # delete any extra trailing /
github_repo_name = File.basename(github_repo_url)

input = if ARGV[1] then File.open(ARGV[1])
        else            $stdin
        end

markdown_list  = []
markdown_links = []

issue_title  = nil
issue_number = nil

begin
  input.each_line do |line|
    line.chomp!

    if line =~ /^[A-Z]/
      issue_title = line.gsub('*',"\\*") # escape any astericks
    elsif line =~ /^#\d+/
      match = line.match(/^#(\d+)/)
      issue_number = match[1].to_i

      markdown_list  << "[#{issue_title}][#{github_repo_name}##{issue_number}]"
      markdown_links << "[#{github_repo_name}##{issue_number}]: #{github_repo_url}/issues/#{issue_number}"

      issue_title  = nil
      issue_number = nil
    end
  end
rescue Interrupt
  exit 130
end

puts

markdown_list.each do |entry|
  puts "* #{entry}"
end

puts

markdown_links.each do |entry|
  puts entry
end

Please @github, add some sort of "Export to CSV" or "Export to Markdown" option.
