Rake extensions to Module.
A Module
is a collection of methods and constants. The methods
in a module may be instance methods or module methods. Instance methods
appear as methods in a class when the module is included, module methods do
not. Conversely, module methods may be called without creating an
encapsulating object, while instance methods may not. (See
Module#module_function
)
In the descriptions that follow, the parameter sym refers to a
symbol, which is either a quoted string or a Symbol
(such as
:name
).
module Mod include Math CONST = 1 def meth # ... end end Mod.class #=> Module Mod.constants #=> [:CONST, :PI, :E] Mod.instance_methods #=> [:meth]
