Refer to a function in enclosing module

General Usage

This stumps me at the moment: How do I refer to f in the submodule?

module A

f(x) = 10*x

module SubA

g(x)  = f(1)

end

end

using .A

@show A.SubA.g(3)

You need to pull f into SubA from A like so:

julia> module A
       f(x) = 10*x

       module SubA
       using ..A: f

       g(x)  = f(1)

       end

       end
Main.A

julia> using .A

julia> A.SubA.g(3)
10

the ..A basically means $EnclosingModule.A like in unixy directories.

Of course, I’ve used this notation many times before. I don’t know, when I looked at this particular example I couldn’t see it. Silly me.

Thanks.
