module_parent

module_parent(m::Module) -> Module

Get a module's enclosing Module. Main is its own parent, as is LastMain after workspace().

Examples

1. Get the parent module:

   julia> module A
             module B
                 module C
                 end
             end
         end
   julia> module_parent(A.B.C)
   B

   This example retrieves the parent module of A.B.C, which is B.

2. Handle the top-level module:

   julia> module M
         end
   julia> module_parent(M)
   Main

   In this case, the module_parent function returns Main as the parent module of M.

3. Handle modules after workspace():

   julia> workspace()
   julia> module N
         end
   julia> module_parent(N)
   LastMain

   After using workspace(), the parent module of N becomes LastMain.

Common mistake example:

julia> module X
          module Y
          end
       end
julia> module_parent(X)
ERROR: UndefVarError: X not defined

In this example, the module X is not defined in the current scope, resulting in an UndefVarError. Make sure the module is defined before calling module_parent.
