Class | Module
In: | lib/rake.rb
Parent: | Object

Rake extensions to Module.

### Methods

const_missing rake_extension

### External Aliases

const_missing | -> | rake_original_const_missing
| Rename the original handler to make it available.

### Public Instance methods

const_missing(const_name)

Check for deprecated uses of top level (i.e. in Object) uses of Rake class names. If someone tries to reference the constant name, display a warning and return the proper object. Using the —classic-namespace command line option will define these constants in Object and avoid this handler.

rake_extension(method) {|| ...}

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
