I’m wondering if there are any general views on the cleanest way to combine files within a module. I have at present three types: Parent, Child1 and Child2. Parent is a synonym for AbstractArray{Complex}, and Child1 and Child2 are both structs that derive from it. All three types are relatively complex with a whole bunch of associated methods, and all are used within a module called MyModule. In order to cut down the size of the file MyModule.jl, I decided to divide the three types into separate files, then recombine them into MyModule.
Now comes my question: Is it more common, or even better, practice to write the files Parent.jl, Child1.jl and Child2.jl as free-floating code that gets included into the middle of MyModule, or is it more common/better to package all three of them into individual modules that are then using-ed into MyModule?
Following this is the additional question of whether there is a standard practice like in C++ of #define-ing constants that avoid the issue of including a file twice into the same code. So like, what if Parent is used by both Child1 and Child2, then both are included into MyModule. What is the standard practice for avoiding the Parent code being included twice into MyModule.
I have various thoughts on these matters, but I’m a relative beginner in Julia and would be glad to hear from more experienced people.
