Primitive Ruby script for checking if a GitHub user login is avalable (you need to have octokit installed). Usage: ruby ghakound.rb <login>, e.g. ruby ghakound.rb defunkt

ghakound.rb

#!/usr/bin/env ruby
#encoding: utf-8 ​
# Checks if GitHub login is taken. Argument -u => login name
# noinspection RubyResolve
require 'optparse'
require 'octokit'
require 'pp'

options = {}
option_parser = OptionParser.new do |opts|
  # Create a flag
  opts.on('-u USER') do |user|
    options[:user] = user
  end
end

begin
  option_parser.parse!
  # puts options.inspect
rescue OptionParser::InvalidArgument => ex
  STDERR.puts ex.message
  STDERR.puts option_parser
end

begin
  command = -1
  user = Octokit.user options[:user]
  puts user.login
  command = 0
  rescue
    puts "Not found"
    command = 1
end
exit command
