# This is kinda trick - since we don't have a autoload and other magic stuff
# like Rails does, so instead this method allows us to replace currently running
# console with a new one via Kernel.exec. It will start console with new code loaded
# Yes we know that it is not turbofast, however it is turbo convinient and small
#
# Also - the KARAFKA_CONSOLE is used to detect that we're executing the irb session
# so this method is only available when the Karafka console is running
#
# We skip this because this should exist and be only valid in the console
# :nocov:
if ENV['KARAFKA_CONSOLE']
  # Reloads Karafka irb console session
  def reload!
    puts "Reloading...\n"
    Kernel.exec Karafka::Cli::Console.command
