rabil95219: If you're interested (like I do) in getting a similar config on two different computers w/ Nix, this is what I do. (There may be other way of doing it but well, mine works well for now).
I fix the doomemacs version via home.file.".emacs.d".source = pkgs.fetchFromGitHub.... This also needs variables (session wide for instance via systemd.user.sessionVariables DOOMLOCALDIR = "$HOME/.local/share/doomemacs"; and DOOMPROFILELOADFILE = "$HOME/.local/share/doomemacs/profiles/load.el"; You need to change this because by default doom & some emacs packages expect to be able to write in .emacs.d.
Afterwards, my repo setup symlinks my emacs config between my git repo and .doom.d to get the same config. :)

How do you deal with extra config stuff then? Write out a file and load it in config.el ?
I'm asking because i used to have a setup like this with NDE

extraConfig = ''
    (setq exec-path (append exec-path '( ${
    pkgs.lib.concatMapStringsSep " " (x: ''"${x}/bin"'') extraBins
    } )))
    (setenv "PATH" (concat (getenv "PATH") ":${
    pkgs.lib.concatMapStringsSep ":" (x: "${x}/bin") extraBins
    }"))
';
