Creating looping matrixes (Torus-like) with type inheritance

Sorry for the delay in the answer, I’ve been busy.

I can’t find out how to rewrite getindex (first one I’ve tried for now)

I’ve created my own struct :

struct LoopArray <: AbstractArray
 #what do I do here ?
end

And then I’ve looked at the code for get index in essentials.jl and in abstractarray.jl but they’re far too complicated to recode because they’re built first with an int index first and then generalized to vector indices.

So I’ve thought about saying something like

Function getindex(LoopArray, index:: AbstractArray)
  index = index modulo array size
 getindex(LoopArray, index) # calling base function now that it's corrected

But won’t my second call just call the first one and loop ?
I’ve searched similar implémentations but couldn’t find one with my needs

Edit : just found this : Arrays with periodic boundaries - #3 by jonathanBieler , I’ll try based on this for now, haven’t finished yet
