 m1-s | I had declared the flake input as github:yesodweb/yesod?dir=yesod-form and it seems that this notation has changed with the nix version update. https://github.com/NixOS/nix/pull/12801
So not related to haskell. Thanks for the quick reaction!

 ivy | the cabal2nix shell keeps failing because it keeps compiling ghc then filling my computer | 02:28:39 |
 maralorn | sterni: Wolfgang Walther I had an insanely busy last two weeks and my boss just decided to give our huge infra structure update (ghcjs 8.6 -> ghc+wasm 9.12) into production this evening. So I am rather confident that I won’t succeed doing anything on our PR. | 15:57:03 |
| maralorn | But I guess we are kinda flying blind because of a rebuild right now anyway? | 15:58:39 |
 sterni | I fixed everything except for HLS pretty much 🫠 | 18:25:52 |
| maralorn | And how broken is that?^^ | 18:26:20 |
| maralorn | As in is that hls 2.11 or 2.12? | 18:27:07 |
| maralorn | Hm, still 2.11. So I wasn’t really expecting any breakage. | 18:37:54 |
| maralorn | But we will see. | 18:37:58 |
|  dotlambda joined the room. | 21:10:44 |
| dotlambda | Where does haskellPackages.hledger_1_50 come from? Does stackage have two versions of hledger or do we always have the pinned or the most recent version? | 21:12:09 |
| dotlambda | Is it possible to make it use hledger-lib_1_50? | 21:12:39 |
| maralorn | dotlambda: https://nixos.org/manual/nixpkgs/unstable/#haskell-available-versions | 21:15:14 |
| dotlambda | If I make a PR removing the pin on hledger, which branch should I target? | 21:18:25 |
| dotlambda | I guess I can't remove it because it's pinned on stackage | 21:24:06 |
| dotlambda | In reply to @robert:funklause.de
Is it possible to make it use hledger-lib_1_50? Still, this would be nice in order to unbreak hledger_1_50 | 21:24:41 |
| maralorn | dotlambda: compare: https://github.com/NixOS/nixpkgs/issues/190542 | 21:24:49 |
| maralorn | Are you currently trying to fix a build error? | 21:25:08 |
| maralorn | I am slightly confused about the problem. | 21:25:17 |
| dotlambda | In reply to @maralorn:maralorn.de
Are you currently trying to fix a build error? Yes. Try building haskellPackages.hledger_1_50. It fails because it needs hledger-lib_1_50. | 21:26:22 |
| maralorn | Yeah, makes sense. | 21:26:37 |
| maralorn | Yeah, you would need to manually override hledger to use the correct hledger-lib version. Belongs into configuration-common.nix. Would be fine to open against master. | 21:27:40 |
| maralorn | Alternatively you remove the stackage pinning from hledger. Which by the issue I linked has been requested multiple times. | 21:28:13 |
| dotlambda | In reply to @maralorn:maralorn.de
Alternatively you remove the stackage pinning from hledger. Which by the issue I linked has been requested multiple times. That might break something that depends on hledger, not sure | 21:28:53 |
| maralorn | Yeah, totally. | 21:29:19 |
| maralorn | Just a suggestion. Do whatever you prefer. | 21:30:24 |
| dotlambda | How would I remove the pinning? | 21:33:33 |
| dotlambda | I guess I add it to update-stackage.sh | 21:33:58 |
| maralorn | Yes, exactly. | 21:34:42 |
| maralorn | If you do that on master you probably want to remove the relevant pins from our stackage.yaml. But I didn’t mean to trick you into doing more work than you set out for. 😄 | 21:36:16 |
