# INTRODUCTION

# This script echos the active Heroku credentials (useful when switching between multiple Heroku accounts
# and remembering which one is active).

# USAGE

# ruby credentials.rb

# CONFIGURATION

HEROKU_HOME = File.join ENV["HOME"], ".heroku"
CREDENTIALS_FILE = "credentials"

# EXECUTION

credentials_path = File.join HEROKU_HOME, CREDENTIALS_FILE
if File.exists? credentials_path
  credentials = `cat #{credentials_path}`.split("\n")
  puts "\nYour active Heroku credentials are:\n\n"
  puts credentials.first
  puts "*" * credentials.last.size
  puts "\nSource: #{credentials_path}\n\n"
else
  puts "ERROR: Heroku credentials not found!"
end
