I've been using doom by just having emacs in my home-manager config and putting the deps it needs on the path into my config as well, and that's been working fine for me. I'm doing this because my doom config uses git submodules and nix chokes on that when I try nix-doom-emacs' home-manager module. I'm satisfied with this for now, except for one thing: the all-the-icons-fonts have not been properly detected by emacs. Is there something I can do to force it to have access to those fonts and use them?

Hooray, more lojban evangelization. Anyway, I have tried ?submodules=1 in the url, however building my home-manager config with nix-doom-emacs and my config hangs, and when I inspect the process tree with htop I see that the process that's stuck is git cloning submodules.

I'm mostly just concerned with getting the fonts working though, because I don't really want to use nix-doom-emacs because I like to edit my config frequently while I'm using emacs, having to rebuild my home config each time sounds like a big annoyance.

I personally know at least 3 other people in the lojban community who use nix

actually four now that I think about Xe

That's a good thought, I should try that after I see if enabling home-manager's fonts.fontconfig option

Actually looks like enabling fontconfig did it

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:

In reply to @roman.gonzalez:matrix.org
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.
