doom cli details

I confirm that...

• I searched the FAQ, issue tracker, discussions board, documentation, and wiki, and did not find an answer to my question.

• Any discussions with or conclusions derived from the use of LLMs will be omitted from my question.

What is your question?

I am trying to set up a home-manager configuration that automatically installs doom emacs from the git repository.
(I am very new to nix, so forgive me if I am being stupid please)

What I am currently thinking about is this; Is it possible to write a derivation that gets the repository, runs doom install and then symlink that into ~/.config/emacs?

I guess what I'm asking is this:
What exactly does doom install modify and what runtime dependencies does it have?

Also. what exactly does doom sync do, because I don't think I can just run it after ~/.config/emacs is already read-only, right?

System information

No response

also, of course, the install needs to be noninteractive

Maybe I’m too late, but in case you still need help with this, I used to install Doom similarly to what you asked, you can check it here.
I don’t anymore, because now I rely on nix-doom-emacs-unstraightened.

Also, I think it’s better to either clone Doom’s repo to its final destination, or at least do the symlinking to ~/.config/emacs before performing the doom install, because some absolute paths may be involved ( I think I had some issues relocating the tree in the past).

Bon chance !

If you want to nixify Doom, nix-doom-emacs-unstraightened is your best bet. Use it directly or as a reference for building your own solution.

What exactly does doom install modify and what runtime dependencies does it have?

It generates the ~/.config/emacs/.local/ directory and generates the current profile (e.g. clones all the requested packages there, generates package autoloads, a couple cache files, and a dynamically generated init.el file that Doom will load at startup). You can change where Doom writes this directory by settings the $DOOMLOCALDIR envvar. It won't write outside of this directory (though, it can't stop any errant packages trying to do so out of band at compile time; I'm not aware of any that do that though).

I generally don't recommend folks nixify Doom, though. It and Emacs are simply too stateful; there are numerous packages with zero chill about writing files to ~/.config/emacs/ during runtime. Doom tries to centralize them to $DOOMLOCALDIR as best it can.

Also. what exactly does doom sync do, because I don't think I can just run it after ~/.config/emacs is already read-only, right?

doom sync only writes in $DOOMLOCALDIR, so as long as that directory is moved out of ~/.config/emacs, then it won't matter that it's read-only. It will break doom upgrade though, which shouldn't be a problem.

Just remember $DOOMLOCALDIR needs to be set anywhere the doom script is used.
