As said in doc [Modules and files](https://docs.julialang.org/en/v1/manual/modules/#Modules-and-files-1), modules can be separated into multiple files like

```julia
module Foo
include("file1.jl")
include("file2.jl")
end

```

However there would be one problem, suppose we are developing a module, and would like to separate implementations into `data.jl`, `func0.jl` and `func1.jl`, and `data.jl` is for definition of structures, `func0.jl` and `func1.jl` are some function definitions, using context of `data.jl` for multidispatch.  
Then it seems the module definition would be

```julia
module MyModule
include("data.jl")
include("func0.jl")
include("func1.jl")
end

```

It works, but the problem is when writing `func0.jl` and `func1.jl`, we do not have definitions of structures, and auto complete/hints may fail.

If we are using python, we may have file structure

```julia
__init__.py
data.py
func0.py
func1.py

```

and simply use `from .data import SomeDataClass` in `func0.py`, I’m wondering what’s the correct julia way of dealing with this.

Which IDE are you using?

Thanks for your reply.

I’m using VS Code, with Julia 1.0.

Although there might be problem caused by extension problems to Julia 1.0.  
Currently VS Code have a minimal support for auto complete if all code were in one file.  
And I’m wondering if I do not put any hint in one file(no include/import/using at all), how can IDE/plugin/extension known where to find definitions?
