Overview

Opal::CliRunners is the register in which JavaScript runners can be defined for use by Opal::CLI. Runners will be called via the #call method and passed a Hash containing the following keys:

  • options: a hash of options for the runner
  • output: an IO-like object responding to #write and #puts
  • argv: is the arguments vector coming from the CLI that is being forwarded to the program
  • builder: a proc returning a new instance of Opal::Builder so it can be re-created and pick up the most up-to-date sources

Runners can be registered using #register_runner(name, runner).
