I’m making my first package for Julia (text generator based on Markov chains) and I’d like it to export two modules: Markovify and Markovify.Tokenizer, so that both will be available to be `used` in the users code. How do I do this as a developer?

Currently I have simply two files with two modules, but only the module named Markovify (which is the same as the package name) seems to be exported.

Thank you.

The user would not be able to input `using Markovify.Tokenizer` before `using Markovify` first. If you wish to be able to load the `Tokenizer` package without first invoking `Markovify`, then it needs to be a separate package, so that the package manager recognizes it separately.

That doesn’t concern me, Markovify.Tokenizer will be used only when using Markovify anyway. Just to be sure; to be able to make this, I should do something like:

file1.jl

```julia
module Markovify
[...]
end

```

file2.jl

```julia
module Markovify
    module Tokenizer
    [...]
    end
end

```

Right?

Probably more like this, actually

Markovify.jl

```nohighlight
module Markovify
include("file2.jl")
[...]
end

```

file2.jl

```nohighlight
module Tokenizer
    [...]
end

```

That was what I’ve been missing! Worked great, thanks. No clue why my version didn’t work, though; any pointers?

In your version you’ve defined two different modules with the same name, `Markovify`. One contained the `Tokenizer` module and one didn’t.

The package manager looks in the `src` directory for a file with the same name as the package, so `file1.jl` will not be found. You have to `include` the other files from the main module file to load them.
