In a project which I’ve been working on, I encountered a situation to flatten a nested tuple but couldn’t come up with a way to do so, hence out of curiosity I started googling about it and came to the following conclusion.
As for an example I had a structure something similar to the one mentioned below, though not identical:
and, supposedly I wanted to make structureToOperateOn something like this:
So the first thing that came to my mind was to use foldLeft:
which resulted in something like this:
Next, I thought of flattening the tuples and came across Shapeless. Although I think scala should have something to flatten tuples, the best way it could be done as of now is to use Shapeless library. Anyways, this is how flattening tuples using Shapeless works:
After messing around with nested tuples, I finally thought it’d be better to have an alternative way to get the required result instead of adding a new library in the project. Regardless, it could be very helpful in scenarios where you might get stuck and would want to ultimately flatten a tuple.
This was what I used as an alternative:
which resulted in:
So to conclude, you can use Shapeless in order to flatten complex nested tuples if need be.
