 Artem | I'm guessing the versions are specified in configuration-hackage2nix/main.yml | 15:23:38 |
| Artem | it says "# This is a list of packages with versions from the latest Stackage LTS release." sadly, it doesn't explicitly say if I can add packages outside of LTS in there | 15:24:56 |
| Artem | but the name of its "extra-packages" field suggested that it's the right place | 15:25:47 |
 maralorn | There is stackage.yaml file, which is auto generated. | 15:25:57 |
| Artem | I don't need that one for adding a non-stackage package, right? | 15:26:50 |
| maralorn | Yeah. | 15:27:18 |
| maralorn | Then there is extra-packages which gives additional versioned attributes. | 15:28:14 |
| Artem | my slight worry about configuration-hackage2nix/main.yml#extra-packages is that every package on that list has a comment saying why it's there, and it's very specific. This makes me question that it's the right place. Unless I'm expected to say "# it's a cool package not on Stakage, but I want it in nixpkgs"... | 15:28:24 |
| maralorn | And default-package-overrides which modifies which version the default attribute has. | 15:29:17 |
| Artem | but adding a package not from Stackage is shouldn't overide anything, so this field isn't applicable, right? | 15:31:41 |
| Artem | * but adding a package not from Stackage shouldn't overide anything, so this field isn't applicable, right? | 15:31:48 |
| Artem | * but adding a package not from Stackage shouldn't override anything, so this field isn't applicable, right? | 15:31:52 |
| Artem | do I need to run anything after updating configuration-hackage2nix/main.yml? the change doesn't seem to get picked up | 15:34:03 |
| maralorn | No, the field is applicable because hackage2nix always has a notion for the default. The default default is the newest version. | 15:37:06 |
 chreekat | Get it included in stackage? 🙂 | 15:37:20 |
| maralorn | Yes maintainers/scripts/haskell/regenerate-hackage-packages.nix | 15:38:01 |
| Artem | yes, I'm contemplating this now. There are some traces of it being there though: https://github.com/commercialhaskell/stackage/commit/c5e992f2a5eb9727c880e92be677d7ded665dc65 so, I guess it's just not the right LTS | 15:43:25 |
| Artem | chreekat: although I don't see it in any of the latest LTSs per GHC versions (I checked for GHC 9.10 and 9.8) | 15:45:30 |
| Artem | are you saying I should use "default-package-overrides" instead of "extra-packages" for a package outside of LTS? (I'm sorry for being slow!) | 15:46:38 |
| Artem | modulo the extension .sh, that started doing something but failed with:

| Artem | I'll have to get back to this. In the meantime, I'm submit a PR unbreaking liquid-fixpoint at least: https://github.com/NixOS/nixpkgs/pull/433722 let me know if it's horribly formatted and against the guidelines... | 16:10:30 |
| chreekat | Looks like it's under "grandfathered dependencies", so probably needs a new champion . https://github.com/commercialhaskell/stackage/blob/master/build-constraints.yaml#L5657 | 16:10:43 |
 sterni (he/him) | Artem: may be https://github.com/NixOS/nixpkgs/issues/400784, try running with --fast | 16:34:07 |
| maralorn | Yes | 17:09:10 |
| maralorn | Ah, oops. | 17:09:24 |
| Artem | --fast did fix it | 19:41:32 |
| Artem | regenerate-hackage-packages.sh seems to reformat the whole hackage-packages.nix. Am I doing something wrong? | 19:53:28 |
| maralorn | Depends on the diff?^^ | 19:54:43 |
| maralorn | Possibly you have the wrong nixfmt in scope? Not sure. | 19:55:10 |
| maralorn | Yeah, nixfmt seems to be picked up from your environment. | 19:56:35 |
