Instance Method Details

#top_level ⇒ Object

To preserve rake as main executable, as the RunMethod::Patch is applied only when Rake::Application requires the Rakefile that loads rake-commander, we need to:

  1. Intercept the execution on the next stage of the Rake::Application#run command, the top_level call, and re-launch the rake application (so it only receives the ARGV cut that the main patch provides)
  2. Ensure that re-launch is done only once.
  3. Ensure that it does exit(0) to the original running application.
