SM's Haskell Survival Guide

Somewhat-repeatable recipes for getting a reliable haskell build toolchain installed as of 2022Q1. You might need to make adjustments, eg on Windows, but hopefully not too many.

Set up with ghcup

Current most popular method. Best way to get native arm tools on mac m1. You can use it to install the compiler ghc, build tools cabal and/or stack, and IDE/editor language server hls (under $HOME/.ghcup). Actively maintained.

• install latest ghcup (manages haskell core tools)
