 emily | I don't understand it either, but also like I said this stuff changed at some point I believe | 17:00:54 |
 piegames | yeah, I figured | 17:01:21 |
 aloisw | In reply to @emilazy:matrix.org
overlays = [ (final: prev: prev.dummyOverlay) ]; should final: prev: prev.dummyOverlay final prev, but yes that works, cool trick. | 17:02:21 |
| emily | that's not the trick I mean :) | 17:02:33 |
| aloisw | Ah you want to use an attrset as an overlay? | 17:03:33 |
| emily | you can do dummyPackages = { nix = pkgs.hello; } | 17:03:34 |
| emily | and then (final: prev: prev.dummyPackages) should work | 17:03:41 |
| emily | that's how lixPackageSets could work (but it does admittedly infrec right now) | 17:04:05 |
| emily | (I guess because it's overlaying newScope, lol) | 17:04:13 |
| aloisw | Yeah I understand now, that's an even cooler trick. | 17:05:08 |
| emily | (extend (final: prev: builtins.removeAttrs prev.lixPackageSets.stable [ "callPackage" "newScope" "overrideScope" "packages" "recurseForDerivations" "stateDir" "storeDir" "confDir" "aws-sdk-cpp" "boehmgc" "editline" ])).lix does still infrec and I don't know why. | 17:05:59 |
| emily | probably because the lixPackageSets themselves get messed up by the overlay and need to be written smarter for it | 17:06:22 |
| emily | or something. | 17:06:32 |
| aloisw | Will try to figure out once my nix-daemon is not longer almost OOMing due to linking a Gecko. | 17:09:21 |

| piegames | nooo we need you | 17:24:39 |

(extend (final: prev: builtins.removeAttrs prev.lixPackageSets.stable [ "callPackage" "newScope" "overrideScope" "packages" "recurseForDerivations" "stateDir" "storeDir" "confDir" "aws-sdk-cpp" "boehmgc" "editline" ])).lix does still infrec and I don't know why. I think it infrecs on the names given that even final: prev: builtins.deepSeq (builtins.attrNames prev.lixPackageSets.stable) {} does. | 17:30:47 |
| emily | I'm so confused. how can a prev thing infrec? | 17:32:49 |
| emily | it's, like, already there. | 17:32:56 |
| aloisw | Hmm even final: prev: prev.callPackages ({ }: { }) { } infrecs. | 17:33:01 |
| aloisw | Might have something to do with the fact that prev is not quite the same as the package set without the overlay. | 17:33:55 |

nooo we need you i feel like there's enough brains on the topic ;P | 17:36:34 |
| raitobezarius (DECT: 7248) | but tbh, I think the package set usage could be simply as lix.packageSet = pkgs.lixPackageSets.lix_2_93; | 17:36:56 |
| raitobezarius (DECT: 7248) | kernel style | 17:36:57 |
| raitobezarius (DECT: 7248) | and then the nixos module can abstract the various overlays we want to do | 17:37:06 |
| emily | do you know how it differs? | 17:43:05 |
| emily | apparently I don't understand overlays | 17:43:08 |
| * piegames is confused as well | 17:46:33 |
| aloisw | This should be the function that applies overlays: https://github.com/NixOS/nixpkgs/blob/1733b682f2b4bf9e389a757e81e09fe3b51ddbc4/lib/fixed-points.nix#L319-L328 . So basically you should think of the package set as a function (that can be altered by overlays) and prev is the package set function prior to your overlay called with the fixed point. | 18:25:19 |
