Hi, sorry for the kind of noob question, but I'm trying to install nix-doom-emacs with home-manager and flakes but I got this error:

Does anyone know how to fix this? Any help is appreciated!

what do you have in ./doom? this looks like the doom cli is trying to write a file in the nix store

at this point, I would recommend reverting the evil-collection dependency resolution to come from emacs (e.g. remove it from the overrides.nix). This may work for Linux folks so no need to stop that from happening.
i've just switched over to nix-doom-emacs and run straight into this issue, so i'm in favour of this fix at least in the short term

@ckie:ckie.devckie (they/them) huh doom still doesn't support Emacs 29 20:02:29
@ckie:ckie.devckie (they/them)goddamn piles of elisp are not fun23:03:15
@ckie:ckie.devckie (they/them)there's so much overhead i can't concentrate on the actual problem because i'm just fighting tooling for hours23:03:43

@petrichor:envs.netJez (he/him) ♾️i tried a few years ago to get this working (when nde was pretty new, i think) and failed, but it went very easily this time so thanks to all the contributors!09:14:27
@petrichor:envs.netJez (he/him) ♾️

a couple of newbie questions:

  1. seems like straight-emacs-env gets fully rebuild any time i make a minor change to my config: i assume that's expected behaviour at the moment but let me know if not?
  2. is there a way of specifying that i'm using a literate config and having config.org tangled to config.el as part of the build? for now i switched to doing it manually when i update config.org
09:21:50
@benedikt:tissot.deBenedikt Tissotin the FAQ there should be a section about how to specify a config to generate the package environment (and the rest empty) such that you only rebuild when package stuff changes. You can also point your config to a nix expression, so you could write a derivation to tangle config.org and then point on the generated config.el.09:28:55
@petrichor:envs.netJez (he/him) ♾️aha, thanks 🙂09:29:27
@benedikt:tissot.deBenedikt TissotSo basically you would generate some derivation for doomPackageDir (for the packages) and then for doomPrivateDir you combine this with your tangled config09:29:28
@petrichor:envs.netJez (he/him) ♾️ok, will play with this a bit to figure it out and then see if it's worth making a pr to add to nde itself09:30:13
@petrichor:envs.netJez (he/him) ♾️oh look, there's already some code i can steal at https://github.com/nix-community/nix-doom-emacs/issues/60 😅09:31:59
@petrichor:envs.netJez (he/him) ♾️that'll teach me to rtfm (spoiler: it probably won't)09:32:14

it's not in the faq, but i found it in a closed issue & pr https://github.com/nix-community/nix-doom-emacs/pull/303
09:36:56
@benedikt:tissot.deBenedikt Tissotoh sorry, I guess this is where I got it from then 🙈🙈09:39:48
@petrichor:envs.netJez (he/him) ♾️tbf it probably should go in the faq, i expect it's a pretty common question09:43:19
