Hi !

I want to include a .jl file in two different ways, according as it is included within a module or on its own. I know this sounds confusing ; here is a way to do it, which I think is awkward, and I’m looking for something more elegant.

so i have `foo.jl` with

```julia
macro in_my_module_only(arg)
    if @isdefined SOME_CRAZY_NAME
        return arg
    else
        return nothing
    end
end

@in_my_module_only begin ... end

```

and then “MyModule.jl” goes like this:

```julia
module MyModule
    SOME_CRAZY_NAME= 1
    include("foo.jl")
end

```

This actually works! However, I’m not sure if this is the right way to go about it. I thought of inspecting the current module with `mod= @ __MODULE__ `, but then I’m not sure what to do. If I inspect `string(mod)` I get `Main.MyModule` typically, but in other situations it would be different… or perhaps I should check that `string(@ __MODULE__ )` contains the substring `MyModule` ?

what do you think?

thanks!  
Pierre

The module of the REPL is called “Main”. So you could check against that.
