@sielicki:matrix.orgsielickiclion is free for OSS work22:19:41
@sielicki:matrix.orgsielickiI'm not super committed to finishing it, but I've been toying around lately with replacing the nix lexer and parser with https://lexy.foonathan.net/ lately22:21:47
@sielicki:matrix.orgsielicki* I'm not super committed to finishing it, but I've been toying around lately with replacing the nix lexer and parser with https://lexy.foonathan.net/ 22:21:53
@sielicki:matrix.orgsielickithe value here is primarily in parsing speed (see lexy benchmarks: https://lexy.foonathan.net/benchmark_json/ ) but also that it would be simple to have a unified parser between nix and json 22:23:30
@sielicki:matrix.orgsielicki * the value here is primarily in parsing speed (see lexy benchmarks: https://lexy.foonathan.net/benchmark_json/ ) but also that it would be simple to have a unified parser between nix and json, and any other parsing that you should want nix to be capable of understanding 22:24:08
@sielicki:matrix.orgsielickiit's trivial to write allocator-aware lexy parsers and/or parsers which defer subexpression parsing. ie: imagine a parser which, in its first pass, scans exclusively for path references and import statements, and aggressively schedules that io work before coming back to parse everything else. 22:30:39
@sielicki:matrix.orgsielickien.cppreference.com/w/cpp/execution can also play a role there22:31:33

@jade_:matrix.orgjade_we use a different parser of similar vibes in lix05:13:34
@sielicki:matrix.orgsielickiwhat's lix?05:13:55
@jade_:matrix.orgjade_uhh, the other major nix implementation, https://lix.systems05:14:07
@jade_:matrix.orgjade_ours is using the pegtl library05:15:01
@sielicki:matrix.orgsielickioh very cool, yeah this looks awesome05:18:46

@mdaniels5757:matrix.orgmdaniels5757 It looks like the security patch for 2.26.3 didn't make it to nixpkgs release-24.11. Should I add the patch for 2.26.3 first, or would merging and manually backporting https://github.com/NixOS/nixpkgs/pull/419839 be easier? @Mic92 01:32:51
@joerg:thalheim.ioMic92it would be05:33:17

@tomberek:matrix.orgtomberekHow intrusive would it be? And can it express the various quirks Nix has?17:29:23
@magic_rb:matrix.redalder.orgmagic_rb Would anyone else be interested in git-annex support? Id like to pair with someone, never did any nix work before. It could even maybe be an out of tree plugin? Essentially just needs to scan all annexed symlinks and then resolve them and put them into the store, or refuse eval if some annexed file is unavailable 17:39:55

@djacu:matrix.orgdjacuHey Nix Team In case you haven't seen the recent post on discourse, the Marketing Team is preparing this year's community survey. I am reaching out to teams to see if there are any questions they would like to add to the survey to better serve the work you all do. More details in the post linked below. https://discourse.nixos.org/t/community-feedback-requested-2025-nix-community-survey-planning/6615503:27:54
@roberthensing:matrix.orgRobert Hensing (roberth)This would be similar to LFS support, iiuc, which is already implemented11:19:06
@magic_rb:matrix.redalder.orgmagic_rb
In reply to @joerg:thalheim.io
how would this be used with nix?
Yeah, as robert said, with the current lack of support, if you have a repository with annex you end up with a bunch of dangling symlinks
