I just wondered about some metaprogramming.
Actually I need to create a method within a method, or just create a method in the root of a class by a block. example:
["method_a", "method_b"].each do |m|
Marshal.generate_a_method_called(m)
end
Does somebody know how this is possible? And where to place what the method does? I need one argument for my method.
Yours,
Joern.
You could use define_method:
[:method_a, :method_b].each do |m|
define_method(m) do
# your method stuff
end
end
I don't understand your example. Are you generating the source for the method as well?
So I will start with an example from the book Perrotta: Metaprogramming Ruby
class MyClass
define_method :my_method do |my_arg|
my_arg * 3
end
end
obj = MyClass.new
obj.my_method(2) # => 6
