Configure oh-my-zsh custom folder through home-manager

[piegamesde]

Currently, programs.zsh.oh-my-zsh.custom simply contains the path to a oh-my-zsh custom directory. It'd be way cooler if I could also specify the content of that directory from home-manager, similar to programs.zsh.plugins.

I do this like this:

{ config, pkgs, ... }:
let
  agnoster-nix-theme = builtins.fetchurl {
    url = "https://gist.githubusercontent.com/chisui/0d12bd51a5fd8e6bb52e6e6a43d31d5e/raw/a97b74ce17c5f1befabe266ccf02a972cab2911b/agnoster-nix.zsh-theme";
    sha256 = "1m7qqrp8z0glnq81c9ldzmm0r42rgdmw8nk9hvssbjphx5khk6z7";
  };
  customDir = pkgs.stdenv.mkDerivation {
    name = "oh-my-zsh-custom-dir";
    phases = [ "buildPhase" ];
    buildPhase = ''
      mkdir -p $out/themes
      cp ${agnoster-nix-theme} $out/themes/agnoster-nix.zsh-theme
    '';
  };
in {
  programs.zsh = {
    enable = true;
    ...
    oh-my-zsh = {
      enable = true;
      plugins = [ "git" ];
      theme = "agnoster-nix";
      custom = "${customDir}";
    };
  };
}

Sorry to revive this thread, but would this still be possible? In the case, I'm trying to add a custom plugin go-task-completions, but there's no real way of doing this since the $ZSH_CUSTOM="" is exported after the plugins=(... ) within the .zshrc when using home-manager.

The around is currently using extraConfig to emulate the custom option, which defeats the existence of the custom options

[chisui]

Why do you need to use ZSH_CUSTOM for that? Couldn't you just add something like this:

let
  go-task-completion = fetchGitHub {
    
  };
in {
  programs.zsh.oh-my-zsh.extraConfig = ''
    fpath+=${go-task-completion}
  '';
}
