 angerman | sterni: nice! We are moving away from Hadrian at IOG. | 21:26:05 |

 alexfmpe | huh looks like there was a common jailbreak in master that got removed at some point during current PR
added it back to 9.12 overrides

| alexfmpe | https://github.com/NixOS/nixpkgs/pull/382159 gets haskell.packages.ghc810.miso building again
however, I just checked and haskell.packages.ghcjs810.miso was already broken in master soooo...moot point? | 00:21:13 |
| alexfmpe | seems to be due several packages present in LTS moved to js backend support without keeping ghcjs compatibility | 00:24:13 |
| alexfmpe | switching cpu from "js" to "javascript" and what not | 00:25:38 |
| alexfmpe | I wouldn't bet on someone being motivated to work on adding backward compat to these packages rather than working on moving to 9.12 js backend | 00:28:32 |
| alexfmpe | so maybe ghcjs is no longer a reason to keep 8.10 around | 00:28:48 |
| alexfmpe | that is, in the hypothetical case of someone using ghcjs with recent-ish nixpkgs | 00:31:12 |
 maralorn | Ah, thank you for figuring that out. | 01:46:59 |
| maralorn | Yeah, especially since we are also resource constraint let’s focus on making the new thing work well instead of investing more work into the old thing. | 01:47:45 |
 @dmjio:matrix.org | yay | 05:07:42 |

 Magnus | I have a feeling of cache.nixos.org not being very up-to-date with Haskell packages, is that the case?
The reason for the feeling is that I seem to end up building HLS from nixos-24.11 a lot.

Is that pkgs.haskell-language-server or pkgs.haskell.packages.${your-ghc-version}.haskell-language-server | 10:58:39 |

As long as you are on a released commit this shouldn't be happening. | 11:07:03 |
| sterni (he/him) | yeah, I'm very interested in what hsyl20 is working on / John has been working towards upstream as well. I've been holding out for a long time for something like that to materialize or all the hadrian regressions being fixed. The latter was probably never going to happen. Now the time has come where we can no longer backpin everything to 9.4 where hadrian doesn't agree with us, so I'll have to bite the bullet and figure a way to do this stuff with hadrian for now. Currently trying to find a way to do this without tricking hadrian into using the native logic, though I may just give up and do something similar to installStage1 | 13:03:55 |
| sterni (he/him) | The terminfo thing is a bit of an experiment on my part to see whether such hadrian patches are going to be reviewed / merged because I suspect that no one really wants to deal with it for one reason or another | 13:05:04 |
| Magnus | It's pkgs.haskell.packages.ghc983.haskell-language-server. | 20:33:37 |
| Magnus | That was my impression too, but my experience says otherwise. | 20:34:06 |
| Magnus | * That was my understanding too, but my experience says otherwise. | 20:34:24 |
| MangoIV | I'm guessing that it just doesn't have hls build for any ghc's package set. the default ghc 9.8 for nixos 24.11 for eample is 9.8.2. | 20:36:12 |
| MangoIV | and in fact, that one is fetched. | 20:37:13 |
| Magnus | So only the default is built and cached? | 21:05:30 |
| maralorn | In reply to @magthe:tchncs.de
So only the default is built and cached? For every major ghc version only the default minor version is cached. | 21:43:17 |

 lazyLambda | https://input-output-hk.github.io/haskell.nix/tutorials/getting-started#scaffolding
I see this works for cabal.project and stack.yaml, does haskell.nix also work for plain .cabal? | 23:31:41 |

 Alex | A message in #haskell:matrix.org has brought microhs to my attention. According to the README, it can be bootstrapped with Hugs so I'm going to try going all the way to building GHC from source. If successful, it could resolve some of our booting woes. | 09:54:08 |
