 emily | I think splicing is maybe the worst trade-off of all time. | 08:11:54 |
| emily | I guess strictDeps isn't exactly related to splicing to be fair. | 08:12:17 |
| emily | they're just all tangled up in one ball of awful | 08:12:26 |
| emily | we have mechanisms that basically nobody understands and that cause all kinds of bad and confusing behaviour, and in return we get a cross-compilation interface that most people don't understand and can't use correctly and have a harder time with than if we just had explicit package sets and monolithic dep lists. yay? | 08:13:27 |
 Alyssa Ross | Yeah... | 08:15:50 |
 Tristan Ross | After https://github.com/NixOS/nixpkgs/pull/365057, I plan on working on https://github.com/NixOS/nixpkgs/pull/376197 and from there, I hope to redo some of lib.systems.elaborate. I've shared with Alyssa my plan, it's to make it use the option system so when we work on what's described in https://github.com/NixOS/nixpkgs/pull/400351#issuecomment-2888530195, we wouldn't have to duplicate things. Likely would have lib/systems/options.nix to describe that and lib.systems.elaborate in lib/systems/default.nix would just handle actually using the options and applying them. | 16:41:46 |
| Tristan Ross | https://github.com/NixOS/nixpkgs/pull/409851 is making it start to become possible to replace things more. I think we need something like this for cxxlib, rtlib, unwinderlib, etc. | 19:46:16 |

Would transforming lib.systems.elaborate adds eval overhead? I found even when I add gccarch condition to canExecute, it increased the eval time by 0.2%, if not noise | 03:08:03 |

| Tristan Ross | I'm not sure, we'd have to benchmark it | 03:08:41 |

| Tristan Ross | https://github.com/NixOS/nixpkgs/pull/410056 is ready. ARM trusted firmware works and with an easy patch, Firefox works. | 02:30:09 |

since foo.dev is to be consumed on buildPlatform We select .dev for buildInputs too, and use it to propagate lib and static which are for hostPlatform | 09:27:25 |
| emily | right. (I think we're agreeing?) | 09:27:54 |

https://github.com/NixOS/nixpkgs/pull/410056 is ready. ARM trusted firmware works and with an easy patch, Firefox works. Ok now that mjolnir isn't removing my every single message, I can link the patch which moves Firefox to using cross stdenvs. https://gist.github.com/RossComputerGuy/525eb9f31ecee52c40338bd0af8cb513 | 13:18:21 |
 Randy Eckenrode | I’d be curious whether that works with building Wine (particularly on Darwin without the hook). | 14:01:30 |
| emily | how much cheaper is instantiating a cross stdenv to instantiating an entire Nixpkgs? | 14:04:50 |
