viraptor	I'll continue with the tools created so far. After that gets integrated, xcbuild usage indeed should be limited to only things that already work well.	13:02:21
nasso	anyone here knows how to pin a cask when using brew-nix? i use it to install bitwig studio (a DAW) but my license only covers up to bitwig 5, and the cask has been updated to bitwig 6 i bisected the repository containing the casks and found the last commit where it was still bitwig 5 but im not sure where to go from there brew-nix gives you a nix-darwin module that just provides an overlay that adds `nixpkgs.brewCasks`. however, i would still like other casks to update, so i cant just use the pinned module/overlay!	16:37:37
nasso	is it possible to override the module/overlay somehow to rename `brewCasks` to something like `brewCasksBitwig5`?? or could i somehow skip the module/overlay? i tried to but when applying the config it gets stuck at "installing_mac" or something	16:39:40
emily	looks like it also exposes a `packages` output	17:20:34
emily	so you can pick that one package out of there	17:20:37
nasso	ah yes i tried that wait cuz im back on my laptop now	17:20:53
emily	(tbh, the overlay doesn't even overlay on top of `pkgs` properly so I'd just use the `packages` output in general 😅)	17:21:00
nasso	in my `home.packages` i tried to add `inputs.brew-nix-bitwig5.packages.aarch64-darwin.bitwig-studio` but when i try to `darwin-rebuild`, it gets stuck like that: building the system configuration... warning: Git tree '/private/etc/nix-darwin' has uncommitted changes warning: Using 'builtins.derivation' to create a derivation named 'options.json' that references the store path '/nix/store/ds2x1l37fidk2b65c4cwg77vp976fbd4-source' without a proper context.

nasso	(i think the warnings can be ignored cuz i always got the same before)	17:24:37
emily	looks like it's just downloading	17:24:39
emily	(slowly, probably)	17:24:43
emily	you can pass `-L` to see the full output	17:24:54
nasso	oh let me try	17:25:02
nasso	oh wait, with `-L` i can see the URL	17:26:06
nasso	what if bitwig is just evil and the servers just don't serve	17:26:28
nasso	okay yeah looks like its just slow as shit, but the URL itself works when i try to download from the web browser so	17:27:26

nasso	IT WORKED I THINK	17:28:34
emily	they want you to upgrade :)	17:29:06
nasso	hell yeah it did thanks! i thought i did something wrong but it turns out i only really tried on shitty wifis (hotel and now train)	17:29:22
nasso	lk scared of keeping the bitwig dot com url i dont trust them keeping it up	17:30:19
nasso	but yeha okay thank you emily once again	17:30:21
nasso	ill get rid of the brew-nix overlay lmao	17:30:31
nasso	yeah okay this clears up some things for me cuz i see a lot of projects use overlay when i feel like they shouldn't (e.g. here they're using an overlay to add something to nixpkgs, but they aren't modifying anything in nixpkgs, so like, whats the point)	17:37:17
nasso	* yeah okay this clears up some things for me cuz i see a lot of projects use overlays when i feel like they shouldn't (e.g. here they're using an overlay to add something to nixpkgs, but they aren't modifying anything in nixpkgs, so like, whats the point)	17:37:26
emily	could override it with a web.archive.org link	17:47:00
emily	overlays compose better and can avoid instantiating a bunch of different copies of Nixpkgs (because of flakes' awful transitive dep handling / `follows` messes etc.), but yeah they also have an awkward shared global namespace like that	17:47:34
nasso	yeah but also i have no idea how i would do that 😶	17:48:00
emily	in particular that specific overlay still uses the `nixpkgs` flake input rather than even using `final` as the package set, so it won't "see" other overlays	17:48:04
emily	probably `.overrideAttrs { src = fetchurl …; }`, but I'm not sure exactly how the `brew-nix` derivations are structured :)	17:48:19
