| @penguincoder:matrix.wolfie.pw | Does anyone have an example for a multiple-project flake.nix (aka microservices) example? I have one repo that boots the entire stack and then each project has their own build requirements. Can/should I use a single flake.nix (and lockfile) so that the entire stack moves forward at the same time or should I separate them all out so that each can move independently?
I haven't found a good example so far.

flake.nix are expected to be always at the repo root | 12:44:34 |
| @penguincoder:matrix.wolfie.pw | That makes sense. What about the lock file? Is there any good way to have one repo track the same revision of nixpkgs in another repo? If I can do that, I think I can make the rest work perfectly. | 13:41:48 |

I'm not exactly sure what you want to do, but maybe inputs.nixpkgs.follows would help https://nixos.wiki/wiki/Flakes#Input_schema | 13:59:13 |

 PowerUser64 | Is there a way to satisfy dlopen() when running cmake from inside a mkShell? I'm making a flake for developing bespoke synth (flake code here), but one of core the libraries it uses (JUCE) likes to dlopen things sometimes, which is problematic when running on NixOS or when trying to run in a reproducible manner, like on a non-NixOS system that happens to have the libs in their expected locations. | 06:17:37 |
| PowerUser64 | My current build process is to cd to the directory (using direnv to get all needed packages), then run the build script created by writeScriptBin | 06:19:06 |
| PowerUser64 | which runs cmake and such | 06:19:23 |
 @2xsaiko:tchncs.de | PowerUser64: usually I think you'd patch dlopen calls to point to absolute paths (if the library path is known at build time) or looked up relative to environment variables, like for example QT_PLUGIN_PATH. Ask in the #nix:nixos.org channel though, I think that's the better place to ask for how to do this | 14:38:24 |
|  @petrichor:envs.net joined the room. | 15:51:50 |
| @petrichor:envs.net | since gitea archive api is compatible with github's is it possible to use a gitea repository as a flake input and have it use the same "fetch an archive" optimisation that's used for github? | 15:53:34 |
| @petrichor:envs.net | or do i need to use "git+https://gitea.example.com/user/repo"? | 15:54:25 |
| @petrichor:envs.net | ah, just looking at https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-flake.html#flake-references
looks like github and sourcehut supported, but i guess i could use the tarball type for gitea/forgejo for now
| 15:57:36 |
| @2xsaiko:tchncs.de | is there a good way to use flakes with the pijul VCS? I'd love to try out pijul because it seems like it improves upon git in a lot of ways, but the lack of flake support is the main reason why I've held off for now | 16:22:19 |

fwiw, it was as simple as:
url = "https://<host>/api/v1/repos/<user>/<repo>/archive/<ref>.tar.gz";
| 18:50:38 |
| @petrichor:envs.net | i tried github:<user>/<repo>?host=<host> but it tried to use /api/v3/… which isn't supported by gitea | 18:51:41 |
| @petrichor:envs.net | but seems like it should be fairly straightforward to implement a gitea: scheme | 18:52:24 |

| emily | https://github.com/NixOS/nixpkgs/pull/240808 is the first step | 00:15:55 |
| @2xsaiko:tchncs.de | oh cool! (though, having flake compat would require completely different implementation in nix itself from what I understand, right?) | 00:21:05 |
| emily | yeah | 00:38:57 |
| emily | it was more "Nix isn't going to add a fetcher for something Nixpkgs doesn't even support" | 00:39:05 |

Ask in the #nix:nixos.org channel though, I think that's the better place to ask for how to do this Thanks! I was actually able to find help on the nixos forum. It turned out I needed to use NIX_LDFLAGS to make ld give the program the things it needed. | 00:49:01 |
