`globalSettings` is for which package? · haskell-flake

Srid said:

No, just the ones specified in packages attrset.

Wait. Hmm. Let's confirm that first. Because line 83 here suggests it only applies if you have settings.<foo>.

This is probably the case

shouldn’t it mapAttrs on config.packages and use config.settings.${name} to get the mod for a given package

Srid (Mar 01 2024 at 12:32):

There can be a case where you have a package in settings attrset, but not in packages.

Shivaraj B H (Mar 01 2024 at 12:33):

Also, when we introduce different settings default here, we might need a way to test if the setting is actually applied.

Srid (Mar 01 2024 at 12:33):

Right. We want to add a dedicated test/??? for this, to check all cases.

Incidentally, as of yesterday, haskell-flake master uses Nix (flake checks) for tests. No more bash scripts. https://twitter.com/sridca/status/1763528379188265314

example/flake.nix, test/*/flake.nix are all candidates for defining these tests.

Right, so merging the attribute names looks like what we need

Srid (Mar 01 2024 at 12:35):

Possibly. In any case, having clear tests cases should also be self-documenting in a way.

Srid (Mar 01 2024 at 12:35):

And allow us to freely refactor things without fear of breaking semantics (because the tests, which encode these semantics, will catch them).

FYI: https://github.com/srid/haskell-flake/commit/307961a20136dd75b761fa0e47b947a6fed757a8

haskellProjectTests is pretty nascent right now, but we can improve it to accommodate our future tests.
