Module: GuessRakeTask

Included in:
Rake::TaskManager
Defined in:
lib/guessmethod/rake.rb

Overview

GuessRakeTask is pretty much a bad idea gone worse. When included into Rake::TaskManager, it overtakes TaskManager’s [] method and tries to guess when the task lookup fails. Use via the grake command, or by adding “require ‘guessmethod/rake’” to the top of your Rakefiles.

Instance Method Details

#guess_brackets(task_name, scopes = nil) ⇒ Object

GuessRakeTask’s magic. Go for Rake::TaskManager’s [] lookup first, then guess at it if it fails.
