An example of using Haskell with Nix
This repository mostly exists as a minimum viable example for myself to refer to when I forget how things work.
# install nix, if you don't already have it
$ curl https://nixos.org/nix/install | sh
# install cabal, if you don't already have it
$ nix-env --install cabal-install
now we are good to go!
we can nix-shell to fire up a shell with the appropriate dependencies
We then need to create a cabal file, from our hpack
buildCabal
No we can just run
nix-build project.nix
to build it. nice,
using nix build is bad though - because it can't cache work as smartly as cabal itself
we can bring up another nix shell with everything we need to build with cabal by running
nix-shell --attr env project.nix
then run
cabal configure
cabal run example
wow. tasty
