 maralorn | default ghc 9.8 has reached master and is heading for nixos-unstable. 🎉 | 08:08:28 |
| maralorn | Argh, my server seems to be replaying the event history in this room … | 09:39:42 |
|  @googleson78:tryp.io left the room. | 15:00:30 |
 vcunat | I canceled https://hydra.nixos.org/jobset/nixpkgs/haskell-updates for now, until we catch up with the staging-next merge.
Hydra has 400k long queue now. While most of that's cached, it takes time. And building the haskell jobset could slow it significantly, I think. (it really was building already) | 15:03:22 |

|  彩娜 🏳️⚧️ joined the room. | 03:06:34 |
| vcunat | It's much better now. Restarted the jobs. | 05:11:45 |
|  yliceee joined the room. | 07:46:49 |
| yliceee | does anyone have an example of a nix flake which uses haskell-flake and installs bash completions with the package? | 07:47:14 |
| maralorn | λlice: Do you mean generating completion for optparse applicative parameters? There is a helper for that in nixpkgs, but I don’t know how to integrate it with haskell-flake.
There might be other venues, where there is more discussion about haskell-flake, the readme is e.g. linking a zulip, since the maintainer of haskell-flake is banned from nixos community rooms.
| 07:54:59 |
| yliceee | yeah i mean im not particularly eager to interact with the dev | 07:55:37 |
| yliceee | but yes that's exactly my usecase. could u link the helper? | 07:56:14 |
| maralorn | https://nixos.org/manual/nixpkgs/unstable/#haskell-package-set-lib-functions | 07:58:15 |
| maralorn | The ominously named file "haskell-modules/configuration-nix.nix" somewhere in nixpkgs contains plenty usage examples. | 07:59:19 |
| yliceee | tysm ! | 07:59:57 |
 oak 🏳️🌈♥️ | Could I get invite to #users:nixos.org channel please? | 08:40:53 |
| yliceee | oh, is that why i can't join the new version? it's invite-only now? | 09:12:17 |
 magic_rb | Yes due to spam | 09:14:34 |
| maralorn | Is there a documented way to get an invite?^^ | 09:41:24 |
| maralorn | I’d also be interested. 😄 | 09:41:34 |
 toonn | Pinging K900 in off-topic is what I've seen. | 09:45:16 |
 shapr | I asked in #matrix-discussion:nixos.org | 14:11:29 |
 pwmosquito | Hey 👋 please delete if it's not allowed but we recently put up a job ad for an SRE at our company:
https://artificiallabsltd.teamtailor.com/jobs/5882832-site-reliability-engineer-sre
which is basically a Nix+Haskell job (with some more usual suspects like Terraform, Docker, Buildkite, AWS) | 17:12:38 |
 m1-s | Hello, does anyone have experience with building haskell on macOS? This project compiles fine on linux where nix uses gcc by default. it fails on darwin however as the default compiler there is clang.

The system has a linux builder vm with nix-darwin enabled but I dont think its related to this error.

| alexfmpe | Maybe this? How old is your nixpkgs? | 21:01:58 |
| alexfmpe | I haven't ran into this in almost a year | 21:02:23 |

You need to use a newer Nixpkgs, because this was fixed a few months ago.
I can't recall what the exact commit with the fix was, but one of the maintainers here likely knows. | 21:30:22 |

https://github.com/NixOS/nixpkgs/issues/149692 Fixed by https://github.com/NixOS/nixpkgs/pull/307880 | 22:24:53 |
| alexfmpe | I'd just bump to recent master and get 9.8.3 as default.
It took like 5s off my reloads on mac | 22:26:27 |
