Instance Method Details

#rake_extension(method) ⇒ Object

Check for an existing method in the current class before extending. IF the method already exists, then a warning is printed and the extension is not added. Otherwise the block is yielded and any definitions in the block will take effect.

Usage:

class String
  rake_extension("xyz") do
    def xyz
      ...
    end
  end
end
