module Wukong
class Runner
# Defines methods to help a Runner class load code passed in
# dynamically on the command-line.

# The default behavior of code in this module is to load any Ruby
# files (ending with `.rb`) passed in the command-line.
module CodeLoader
# Loads all code, whether from a deploy pack or additionally
# passed on the command line.

# Load any additional code that we found out about on the
# command-line.

# @return [Array<String>] paths to load culled from the ARGV.

# Loads a single Ruby file, capturing LoadError and SyntaxError
# and raising Wukong::Error instead (so it can be easily captured
# by the Runner).
