.irbrc that runs Pry instead of IRB

if defined?(::Bundler)
  global_gemset = ENV['GEM_PATH'].split(':').grep(/ruby.*@global/).first
  if global_gemset
    all_global_gem_paths = Dir.glob("#{global_gemset}/gems/*")
    all_global_gem_paths.each do |p|
      gem_path = "#{p}/lib"
      $LOAD_PATH << gem_path
    end
  end
end

# Use Pry everywhere
require "rubygems"
require 'pry'
Pry.start
exit

I use following one-liner because it leaves irb command unchanged and bundle console runs whatever you have in Gemfile (eg. bundle console development). And use pry if you want repl without Gemfile.

echo "Pry.start || exit rescue LoadError" > ~/.irbrc

Thanks for sharing this
