See what's going on in your .git folder when you perform git commands

watch_git.rb

# I used this to monitor changes to the .git folder during
# my Austin on Rails lightning talk on Understanding Git.
#
# I ignore any changes to the .git/logs folder, because they are
# noisy and don't add a lot to understanding.
# If you want "the whole truth", remove the :ignore parameter below.
#
# ruby listen.rb <path to .git folder>
#
# gem install listen # its the foundation of Guard
require 'listen'
path_to_watch = ARGV[0] || '.'
last_change = Time.now

Listen.to(path_to_watch, 
          :relative_paths => true, 
          :ignore => /logs\//) do |modified, added, removed|
  # cheap way to add some separation between output from git commands
  latest = Time.now
  if (latest - last_change > 1)
    last_change = latest
    puts "\n\n"
  end
  modified.each{|m| puts "\e[33mCHANGED\e[0m  #{m}" }
  added.each{|m|    puts "\e[32m  ADDED\e[0m  #{m}" }
  removed.each{|m|  puts "\e[31mREMOVED\e[0m  #{m}" }
end

👍 thats cool
