hs-flake-utils
A nix flake for use with Haskell, for Least Authority.
How do I make it go?
- create a directory change into that directory
- nix shell nixpkgs#cabal-install nixpkgs#ghc cabal init and answer all the questions to create the project files
- copy the project template below into a file named
flake.nix
replace the contents ofdescription
andpackageName
in the newly createdflake.nix
- run
nix develop
Wait for the world to build or the internet to send you cached packages.
