 @ronnypfannschmidt:matrix.org | im wondering - are there any experiments on how to have a library system for derivations, dependencies and so on - preferably without suckering into pkgs.lib
im looking for stuff to make more easy autoupdaters, service specs, state management | 18:45:55 |

yeah you're not allowed to do that sorry I mean, it works enough for my use case. :D | 20:00:59 |
| emily | well, it doesn't work for nix flake check :) | 20:01:34 |
| qu4pk4 | Is there a good reason, why it doesn't/cannot work? | 20:02:02 |
| qu4pk4 | My Flake is part of a research into libs/pkgs, so I am ok with it not fitting 100% into the infra. | 20:02:50 |
| qu4pk4 | Nix doesn't seem to be used much for supporting any version of lib, but the strictness and constraints feel like a good match for that use case. | 20:04:32 |
| qu4pk4 | Especially, for research reproduceability. | 20:04:52 |
| qu4pk4 | Another thing: installCheck phase is ran when doInstallCheck is set to true according to https://nixos.org/manual/nixpkgs/stable/#var-stdenv-doInstallCheck, but not when cross-compiling. I can't get my installCheck phase to run in a flake that uses flake-utils. Is the cross-compiling kicking in? | 20:13:20 |
| qu4pk4 | I am building with nix build '#pkg.ver' therefore I am not really thinking I am cross-compiling. | 20:13:48 |

Is there a good reason, why it doesn't/cannot work? the schema forbids it. legacyPackages lets you put arbitrary data in, which is why Nixpkgs uses it | 20:15:37 |
 tomberek | qu4pk4: Eelco is working on a flake-schemas effort to make supporting various schemas in the the top-level outputs. Regardless, you can place a "lib" wherever you wish. Nixpkgs itself places "lib" output into the top-level of the flake. | 22:29:56 |

| qu4pk4 | Thanks | 07:44:21 |
| qu4pk4 | How to use passthru.tests for testing Flake package builds? My idea is to build static libraries and tests that the lib<name>.a indeed exists by compiling a simple source. | 07:45:44 |
| qu4pk4 | But pkgs.runCommand used in https://nixos.org/manual/nixpkgs/stable/#var-meta-tests-nixos does not result in a derivation and therefore both nix run and nix build complain. | 07:46:46 |
| qu4pk4 | Or are passthru.tests somehow ran automatically on nix bulid '.#<pkg>'? | 07:48:45 |

 Šimon Brandner | Hi, I am developing a pam module. How would I test the Nix module (and therefore the Pam module) without having to rebuild my system everytime I make a change and want to test it? Is there something clever I can do? | 14:04:48 |
 Benedikt | You could use the nixos VM test (see the manual and the wiki about that) | 14:17:34 |
| Benedikt | It could be hard to set the test up though (depending on what part of pam you want to test) | 14:18:25 |
| Šimon Brandner | It does sound rather complex but I'll at least have a look | 14:28:58 |
| Šimon Brandner | Ok, a simpler question: how would I add a new PAM rule in my NixOS config? | 14:40:36 |
| Benedikt | I'm not so familiar with pam, but its probably listed in the option search? | 19:01:47 |
