@maralorn:maralorn.demaralornAre you sure this is because of a nix update? Seems kinda unlikely.19:32:31
@maralorn:maralorn.demaralornCan you share the command you ran?19:32:49
@maralorn:maralorn.demaralornMaybe a tree listing of /nix/store/kbv83vqvvc3gczpfz84jycrcp00yx81y-source can be informative.19:34:26
@m1-s:matrix.orgm1-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:faggot.shivy the cabal2nix shell keeps failing because it keeps compiling ghc then filling my computer 02:28:39
@maralorn:maralorn.demaralorn 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:maralorn.demaralornBut I guess we are kinda flying blind because of a rebuild right now anyway?15:58:39
@sternenseemann:systemli.orgsterni (he/him) I fixed everything except for HLS pretty much 🫠 18:25:52
@maralorn:maralorn.demaralornAnd how broken is that?^^18:26:20
@maralorn:maralorn.demaralornAs in is that hls 2.11 or 2.12?18:27:07
@maralorn:maralorn.demaralornHm, still 2.11. So I wasn’t really expecting any breakage.18:37:54
@maralorn:maralorn.demaralornBut we will see.18:37:58
@robert:funklause.dedotlambda joined the room.21:10:44
@robert:funklause.dedotlambda 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
@robert:funklause.dedotlambda Is it possible to make it use hledger-lib_1_50? 21:12:39
@maralorn:maralorn.demaralorn dotlambda: https://nixos.org/manual/nixpkgs/unstable/#haskell-available-versions 21:15:14
@robert:funklause.dedotlambdaIf I make a PR removing the pin on hledger, which branch should I target?21:18:25
@robert:funklause.dedotlambdaI guess I can't remove it because it's pinned on stackage21:24:06
@robert:funklause.dedotlambda
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
