Hi Community,

I’m trying to structure my Julia Project but failing to import modules from one dir to another dir. Below is my Project Structure

```julia
|--Algorithms
    |-- src
       |--Algebra
             |-- algebra.jl
             |-- Testalgebra.jl
       |-- maths
             |-- maths.jl
             |-- Absolute.jl
    |-- Algorithms.jl

```

I’m trying to import Module Maths defined in maths.jl to TestAlgebra.jl, But I’m having no clue. Getting below Error Message.

WARNING: could not import Algebra.Maths into Algebra

Note: I don’t want add include in TestAlgebra.jl as I’ve already added in Algorithms.jl

The contents can be found in this link.

Thanks

Here is the code peiced together with the `include`s removed

```julia
module Maths
	function abs_value(x)
    	return x>0 ? x : -x
	end
end

module Algebra
	import ..Maths
	function add_value(x)
    	return Maths.abs_value(x)+5
	end
end

print(Maths.abs_value(-98))

```

Notice that ive changed `.Maths` to `..Maths` because its in a parent module

Thanks Graham, for the solution.

Is there a better way or standard Julian way to write Imports.

In Algorithms.jl File, the code doesn’t speaks from where module - Algebra got imported:

```julia
include("maths/maths.jl") # Maths Directory
include("Algebra/algebra.jl")
print(Algebra.add_value(-98))

```

Code maintainence will be an issue if codebase becomes larger. How can I address this ?

For most projects I try not to use sub modules. I divide projects into separate files or even folders, but generally they are usually just all included in one single module. But that’s just me.
