directVSmonad

An exploration of direct and monadic patterns for solving nontrivial problems.

What is this about?

There are a variety of strategies for handling control flow tasks in Scala. Unfortunately, many examples are so simplistic that they don't really showcase the challenges and advantages one faces in a realistic, nontrivial scenario.

This repository is a place to explore more hefty challenges for different styles of flow control and abstraction. There's no "a monad is like a burrito" here; we'll assume you have at least a basic familiarity with the styles and simply want to see reasonable solutions to not-straightforward problems.

How is this organized?

Each folder contains a different challenge. Within that folder, there is a single ChallengeWhatever.scala file that contains the challenge as a library, and a set of SolutionSoAndSo.scala files that each contain a different way to solve the problem, which are intended to be run with scala-cli using

scala-cli SolutionSoAndSo.scala ChallengeWhatever.scala

(plus JVM arguments if necessary, since using jvm doesn't always work).
