Doom Emacs

[jespada]

Hi @dustinlyons ,
Thanks for your work, I'm moving all my nix setup to this model, I was wondering where or how would you go about adding Doom Emacs in this type of setup, I like the ideas behind https://github.com/MatthiasBenaets/nixos-config/blob/master/modules/editors/emacs/doom-emacs/default.nix.
Any comments would be helpful.
Thanks

Hi,

I agree that https://github.com/MatthiasBenaets/nixos-config/blob/master/modules/editors/emacs/doom-emacs/default.nix looks promising, especially given the broken state of nix-doom-emacs. Given it's a system option, you should be able to add something like his activationScript to hosts/darwin/default.nix.

You could also look to just add an overlay that does these steps, which runs on every build. Ultimately you want to test a series of steps (i.e a script) that bring Doom to the state you like, and then just stick those in either an activationScript or an overlay.

I personally like using overlays and this project runs each overlay as part of rebuild. This is a good reference to see how overlays work: https://github.com/jwiegley/nix-config/tree/master/overlays

@dustinlyons is there a reason why only emacsclient is on the $PATH and not emacs binary ? is this default in the overlay ?

[dustinlyons]

My configuration uses Emacs daemon mode, so emacsclient connects to the daemon. You can just as easily run the emacs binary but it will boot much slower. I prefer to always have it running, and my configuration is organized around that.

Ah make sense, that's what I've thought, doom emacs wants the emacs bin to be in the path at install time , but other than that I also like to run it as a daemon.
If I want to have emacs in my path along with emacsclient where should I enable that? sorry for the newb question.

[dustinlyons]

The emacs binary sits in /run/current-system/sw/bin. You can add that to your path here:

nixos-config/modules/shared/home-manager.nix

Line 41 in e07ef74

export PATH=$HOME/.pnpm-packages/bin:$HOME/.pnpm-packages:$PATH
