module_function

[Patrick Li]

Hi,
I'm having some trouble using module_function correctly. If someone
could help me it'd be great.

I have a module M that defines method a().
I would like for a() to be callable by M.a() or include M; a();

However (and this is where my problem lies)
a() calls the helper method b().

module M
module_function
def a
b
end

private
def b
#helper method
end
end


This throws a NoMethodError when I try to call M.a(), because it looks
for M.b() (but there isn't and shouldn't be any).

What's the normal way for resolving this?
Thanks a lot for your help

One way is to say, "to hell with module_function":

module M
extend self

def a
b
end

private
def b
#helper method
end
end
