@kranzes:matrix.orgIlan Joselevich (Kranzes)Is there a place explaining NIX_PATH parsing with more complex paths like "nixpkgs=flake:github:NixOS/nixpkgs/nixos-22.05" which include many colons?17:08:25
@kranzes:matrix.orgIlan Joselevich (Kranzes)I'm trying to implement the full NIX_PATH parsing logic in snix but I dont even understand the behavior in Nix.17:09:17
@kranzes:matrix.orgIlan Joselevich (Kranzes) Could someone write a NIX_PATH string that includes all the 5 search path attrsets in this example? https://nix.dev/manual/nix/2.33/language/builtins#builtins-findFile 17:11:33
@kranzes:matrix.orgIlan Joselevich (Kranzes)(If that's even possible?)17:11:56

(If that's even possible?)
Looking at the code, it's not; -I only works because it skips parseNixPath or something
17:16:32
@ss:someonex.netSomeoneSerge (back on matrix)But nix path parsing is already stateful, so you could make a backwards incompatible change to accommodate those?17:18:07

Greedy behaviour here would have been nice, but from my discussion with raito that’s not exactly a priority atm

@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Valentin had a meme for this17:40:23

@raitobezarius:matrix.orgraitobezariusit would be ideal to find a path forward to destroy NIX_PATH parsing18:15:16
@raitobezarius:matrix.orgraitobezariusespecially due to the meme18:15:24
@kranzes:matrix.orgIlan Joselevich (Kranzes) https://gist.github.com/Kranzes/da0ee0920adf9ce94183b6cec3bbe9c2 18:24:28
@roberthensing:matrix.orgRobert Hensing (roberth)I think a lot of folks share that sentiment, on a spectrum between discourage and destroy. What would you suggest for a solution?18:24:30
@kranzes:matrix.orgIlan Joselevich (Kranzes)FWIW: That search path is taken from the docs of findFile, makes it a whole lot more confusing when you realize it works with -I but not with NIX_PATH18:25:12
@raitobezarius:matrix.orgraitobezariusThere's not much solutions to propose at this step18:25:26
@raitobezarius:matrix.orgraitobezariusIt depends on a rework of the setting system18:25:32
@raitobezarius:matrix.orgraitobezariusbecause it is deeply related to that18:25:36
@kranzes:matrix.orgIlan Joselevich (Kranzes)FWIW, I get totally different behavior on Lix, something with how Lix ignores NIX_PATH with flakes maybe? I'm really not sure18:26:53

I also have a feeling that port in URL’s authority will parse funnily
18:27:11
@kranzes:matrix.orgIlan Joselevich (Kranzes)They do.18:28:08
@kranzes:matrix.orgIlan Joselevich (Kranzes) Try this one /nix/var/nix/profiles/per-user/root/channels:nixos-config=/etc/nixos/configuration.nix:nixpkgs=https://github.com/NixOS/nixpkgs/tarballs/master:nixpkgs=channel:nixpkgs-unstable:foo=http://example.com:8080/path:flake-compat=flake:github:edolstra/flake-compat 18:30:18
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Indeed quite funny (in a sad way)18:31:19
@roberthensing:matrix.orgRobert Hensing (roberth)I hate that NixOS populates a local registry nowadays18:32:22
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)I forget the distinction between local and system one18:33:13
@roberthensing:matrix.orgRobert Hensing (roberth)ohh right there's more local ones? Do they even have defined names? I hate it18:34:18
