The question isn’t too clear but as far as I understand you want to use a module inside another one.

You can either define the module in a file and include that file using `include(filename)` then run `using modulename`. But you will have to make sure both files are in the same directory.

Or you could do `PkgDev.generate(packagename, license)` to make a folder for your package in the .julia\v0.6 directory then copy your source code to .julia\v0.6\packagename\src making sure the main file is named “packagename.jl”. Then you call `using packagename` from any other file, REPL session or notebook session, and the package will be available to you.

You can find more details on both of these methods in the docs.

I am not sure if that’s what you were asking about but it seems more of a Usage question than a Development one. Development is more about the Julia internals and language design.

Moved it (I still don’t understand the question though).
