Alyssa Ross	I must have misunderstood your previous message then	11:02:46
@linus:schreibt.jetzt	In reply to @ulrikstrid:matrix.org Was nix initially written in perl? 🤔 https://github.com/nixOS/nix/pulls?q=is%3Apr+is%3Amerged+rewrite+c%2B%2B	11:03:03
das_j	Also yes, it partially was perl	11:03:23
@linus:schreibt.jetzt	oh actually https://github.com/NixOS/nix/milestone/6?closed=1 is a better overview.	11:04:06
@grahamc:nixos.org	Perl has very little code that justifies being written in C++, I'm pretty sure it was picked for the website because it both had a popular web framework and the Nix contributors had experience	13:48:52

samueldr	am I alone in thinking it is a surprising behaviour when executing hydra with foreman that evals being affected by the ambiant NIX_PATH is surprising?	04:47:45
samueldr	the eval used `import <nixpkgs> {}`, and `nixpkgs` was an input of the build (a git checkout)	04:48:44
samueldr	it ended-up trying to import `<nixos-config>` for its overlay, and failing on a further path import disallowed by restricted eval	04:49:13
samueldr	btw, I'm using a foreman-started hydra as a sort of better UX around `nix-build` for a complex project... it's hard to get a good bird's eye view of what is going on	04:51:44
K900	In reply to @k900:0upti.me OK whomst do I poke here to get https://github.com/NixOS/hydra/pull/1243 merged Not to be too annoying but bump	07:12:01
	greaka changed their display name from greaka ⚡️ to greaka .	09:25:58
samueldr	ignore the fact that it's not a valid way to evaluate Nixpkgs	21:18:26
samueldr	* ignoring the fact that it's not a valid way to evaluate Nixpkgs	21:18:32
samueldr	am I missing something obvious with hydra jobset inputs?	21:19:04
samueldr	$ NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/1905f5f2e55e0db0bb6244cfe62cb6c0dbda391d.tar.gz nix repl Welcome to Nix 2.7.0.

samueldr	* `$ NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/1905f5f2e55e0db0bb6244cfe62cb6c0dbda391d.tar.gz nix repl Welcome to Nix 2.7.0.

samueldr	Download image.png	21:19:50
samueldr	assuming the inputs work like `NIX_PATH` does, I would expect this to eval at least up to failing within the eval of Nixpkgs stuff	21:20:36
samueldr	`hydra-eval-jobs returned exit code 1: error: file 'nixpkgs/default.nix' was not found in the Nix search path (add it using $NIX_PATH or -I) error: worker error: error: file 'nixpkgs/default.nix' was not found in the Nix search path (add it using $NIX_PATH or -I)`	21:20:42
samueldr	relatedly, I'm trying to simulate another more involved issue where similarly `import <some-url-to-tarball>` within hydra will try to import the raw tarball, but when provided as `NIX_PATH` to a norma Nix eval it unpacks it before making it available	21:24:33

kayla (she/they)	I'd like to be able to use declarative jobsets in hydra to spawn jobsets for all unmerged branches(essentially the parsed result of `git branch --no-merge main`). I figure `[dynamic]runCommand` will be useful for this but I've not been able to figure out a path of least resistance? (eg, how to get the branch information without inflating evaluation time by a lot, in the case of large repositories). I've tried to go though the git protocol api docs but they seem to be broken on the site right now. Has anyone else done this with a generic git host and hydra? Alternatively, is there a way to get branch merged information when doing `git ls-remote`?	21:37:06
