haskell-template provides a builtin list of flake checks:
haskell-language-server check (
hlsCheck.enable = true) from
haskell-flake: Tests that HLS continues to work with the project.
- treefmt check: Tests that the project is autoformatted and does not have any hlint warnings.
nix flake check and IFD
You cannot use
nix flake check (unless your
systems list is singular) due to IFD. You can work around this by using the check-flake flake-parts module; make the following changes to your
check-flake.url = "github:srid/check-flake";to “inputs”
Now you can run the following command 1 to run all flake checks locally for the current system:
nix --option sandbox false build .#check -L
sandbox is being disabled because of an issue with haskell-language-server.
