@jade_:matrix.org@jade_:matrix.orgwhether that was actually advisable or not is another question hehehe21:17:25
@infinisil:matrix.orginfinisil They only killed nix-channel! 21:17:28
@infinisil:matrix.orginfinisilChannels are still very much needed and alive21:17:36
@infinisil:matrix.orginfinisilWell not that much actually21:18:04
@jade_:matrix.org@jade_:matrix.org (nix-channel and the idea of mutable channels is like. genuinely Bad, but it would be nice if we could have postprocessed versions of nixpkgs instead of just source code, that are actually pinned) 21:18:11
@infinisil:matrix.orginfinisilAt least programs.sqlite clearly demonstrates that channels can have huge value. And flakes could make use of that too21:18:33
@infinisil:matrix.orginfinisil I like how npins supports channels natively 21:19:44
@infinisil:matrix.orginfinisil So if you do npins add channel nixpkgs-unstable and use the resulting Nixpkgs to build your NixOS system, you get an prebuilt always-up-to-date binary lookup for free! 21:20:20
@infinisil:matrix.orginfinisil Without nix-channel! 21:20:43
@ma27:nicht-so.sexyma27 joined the room.21:47:40
@tomberek:matrix.orgtomberek Apologies for the re-start of a topic, but regarding the mentions above for makeScope, I've experimented with a variant of it that can be used with nested attrsets that was quite pleasant to use (ie; the // was not destructive and allowed for adding things to pythonPackages in a composable manner). +1 on the topic of improving the usage of package sets. 22:48:13
@growpotkin:matrix.orgGrowpotkinPlease - let me split `makeScope` into reusable and well documented helpers. 22:50:15
@tomberek:matrix.orgtomberekand use them in Nixpkgs, to help make everything behave consistently? (asking for a friend ;) )22:51:29
@growpotkin:matrix.orgGrowpotkinThat function is THE CORE of `nixpkgs` and currently it's really really hard to grok. It legitimately took me like 6 months of fiddling with similar routines to realize "I just spent months rewriting `makeScope`, and now I actually understand what it was doing" 🤣 22:52:04
