 Robert Hensing (roberth) | Seems to be just an oversight. I'd be happy to accept PRs for these things, or even issues to track in the C API milestone | 08:53:42 |
 sodiboo | yeah i guess that's why it's not like, stable yet, lol. | 09:17:35 |
| Robert Hensing (roberth) | The original contributor for the C API tried their best, but their use case did not include externals. We could strip out the externals and call it stable if you prefer, or we could accept the status quo, or we could accept contributions. I think we're going for the latter, but we could change our strategy | 16:21:15 |

| BenjB83 changed their display name from BenjamÃn Buske to BenjB83. | 10:43:21 |
| sodiboo | for functions taking a nix_get_string_callback, when they return NIX_OK, is the string callback guaranteed to have been called exactly once, and never again? | 15:41:33 |
| Robert Hensing (roberth) | I believe that's the contract yes. I wouldn't rule out multiple calls for sets of strings or something in the future, but that will be clearly documented then | 15:58:51 |

| @acidbong:envs.net | afternoon, fellers and felines
i hope this is the right channel to ask: is there a language-agnostic API for Nix daemon or does it require C bindings? i'd love to try to use a different language instead of Nix | 11:44:47 |
| Robert Hensing (roberth) | Reimplementations exist, but I don't have recommendations. Using the C API would be possible, but the store layer C API is very minimal at the moment; just enough to supplement the evaluator C API; not much more than the ability to have a Store, a StorePath and build a derivation | 20:31:18 |
| @acidbong:envs.net | got it
and I just realized that i'd rather use a transpiler to Nix to do what i want
anyway, thx | 20:34:16 |

 Leonardo Santiago | should I be able to copy derivation closures between remote stores without passing through my own local machine? | 12:08:35 |
| Leonardo Santiago | I tried doing it through the FFI but it grinds to a halt and never returns | 12:08:52 |
|  Sergei Zimmerman (xokdvium) changed their display name from xokdvium to Sergei Zimmerman (xokdvium). | 21:12:16 |

| yorickvp | in theory yes, in practice I think the copying code does some calls that aren't efficient if both stores are remote | 14:20:54 |

| Robert Hensing (roberth) | Heads-up regarding libflake initialization breaking in 2.28 https://github.com/roberth/nix/blob/0c75581d8b7cfbfa7a8db9b5dcbf0cbf0709009f/doc/manual/rl-next/c-api-flake-init.md | 18:06:59 |
| Robert Hensing (roberth) | I've decided to keep it simple and break this, since the changed solution is a recent addition, and C API progress is slow enough as is. Contributions welcome :) | 18:09:40 |

| Robert Hensing (roberth) | we don't have a solution for actually loading settings yet | 14:47:30 |
| Leonardo Santiago | I'm getting SIGSEGV when calling nix_get_attr_byname with (what it seems to me are) completely valid arguments, that shouldn't even throw an error. | 16:15:40 |
| Leonardo Santiago | This is as much information as I can gather from gdb, as I don't know how to enable debug information on the nix C API, for some reason setting dontStrip = true doesn't work for the nix-{x}-c packages.

| Leonardo Santiago | Not sure how to improve this report, the nix expression is fairly complex and I can't include it, but the program itself should just call eval on an expression from file then access its attributes one by one in a list. I'd like to get some line number information going on but I don't seem to be able to. | 16:20:23 |
