Provide a way to customize the xdg-user-dirs #33282

tiramiseb · 2018-01-01T17:14:01Z

The xdg-user-dirs package contains a file named etc/xdg/user-dirs.defaults.

A module allowing to customize this file would be great.

The text was updated successfully, but these errors were encountered:

GNOME users, at least, already have ~/.config/user-dirs.dirs generated in their profile by the GNOME module. That would override the XDG module.

tiramiseb · 2018-01-02T07:23:49Z

The xdg-user-dirs-update command, executed in the GNOME session script you are referring to, reads the user-dirs.defaults file, translates it if needed and places it in ~/.config/user-dirs.dirs. Yes, this is exactly what I am talking about.

If etc/xdg/user-dirs.defaults can be customized, then the GNOME session script would copy the customized one.

This looks like a duplicate of #16200.

The environment variable $XDG_CONFIG_DIRS determines the search paths for user-dirs.defaults. This is currently defined as a profile-relative path variable. For this to work, I think it would also need to define /etc/xdg as a profile non-relative path so that a module could produce the user-dirs.defaults file in that path.

I'm also interested in a way to customize xdg-user-dirs

jtojnar · 2019-08-21T17:43:32Z

There is little need for dedicated options, you can just use

{
  environment.etc."xdg/user-dirs.defaults".text = ''
    DESKTOP=Desktop
    DOCUMENTS=Documents
    DOWNLOAD=Downloads
    MUSIC=Music
    PICTURES=Pictures
    PUBLICSHARE=Public
    TEMPLATES=Templates
    VIDEOS=Videos
  '';
}

in your configuration.nix.

dasj19 · 2019-08-22T08:27:08Z

@jtojnar It does not work...
What I have tried so far in a VM:

removing the user homedir + nixos-rebuild switch --upgrade
changing environment.etc."xdg/user-dirs.conf".text to environment.etc."xdg/user-dirs.dirs".text + removing the user homedir + nixos-rebuild switch --upgrade
changing environment.etc."xdg/user-dirs.conf".text to environment.etc."xdg/user-dirs.default".text + removing the user homedir + nixos-rebuild switch --upgrade

I am using Gnome as a DE and the following user-dirs structure:

environment.etc."xdg/user-dirs.conf".text = ''
    XDG_DESKTOP_DIR="$HOME/system/desktop"
    XDG_DOWNLOAD_DIR="$HOME/downloads"
    XDG_TEMPLATES_DIR="$HOME/system/templates"
    XDG_PUBLICSHARE_DIR="$HOME/system/public"
    XDG_DOCUMENTS_DIR="$HOME/documents"
    XDG_MUSIC_DIR="$HOME/media/music"
    XDG_PICTURES_DIR="$HOME/media/photos"
    XDG_VIDEOS_DIR="$HOME/media/video"
  '';

jtojnar · 2019-08-22T09:22:40Z

nixos-rebuild switch --upgrade will not be enough. xdg-user-dirs relies on /etc/xdg/autostart to run so you need to re-login for it to be triggered.

dasj19 · 2019-08-22T09:48:49Z

I did reboot the VM after every nixos-rebuild switch --upgrade and then logged in as the unpriviledged user

jtojnar · 2019-08-22T11:33:36Z

Hmm, apparently, it should have been user-dirs.defaults, not user-dirs.default or user-dirs.conf.

dasj19 · 2019-08-24T11:39:38Z

@jtojnar ... sorry for the delay...
But I just tried with only this configuration.nix


{ config, pkgs, ... }:

{

  imports =
    [ # Include the results of the hardware scan.
      ./hardware-configuration.nix
    ];

  # Use the GRUB 2 boot loader.
  boot.loader.grub.enable = true;
  boot.loader.grub.version = 2;

  # Define on which hard drive you want to install Grub.
  boot.loader.grub.device = "/dev/sda"; # or "nodev" for efi only

  networking.hostName = "nixos"; # Define your hostname.

  # Enable the X11 windowing system.
  services.xserver.enable = true;
  services.xserver.layout = "es";

  # Set your time zone.
  time.timeZone = "Europe/Copenhagen";


  environment.etc."xdg/user-dirs.defaults".text = ''
    XDG_DESKTOP_DIR="$HOME/system/desktop"
    XDG_DOWNLOAD_DIR="$HOME/downloads"
    XDG_TEMPLATES_DIR="$HOME/system/templates"
    XDG_PUBLICSHARE_DIR="$HOME/system/public"
    XDG_DOCUMENTS_DIR="$HOME/documents"
    XDG_MUSIC_DIR="$HOME/media/music"
    XDG_PICTURES_DIR="$HOME/media/photos"
    XDG_VIDEOS_DIR="$HOME/media/video"
  '';

  # Enable the GNOME Desktop Environment.
  services.xserver.displayManager.gdm.enable = true;
  services.xserver.desktopManager.gnome3.enable = true;
}

And it does not use the user-dirs I configure above

jtojnar · 2019-08-24T13:36:29Z

Okay, there are several issues here:

As Provide a way to customize the xdg-user-dirs #33282 (comment) correctly points out, XDG_CONFIG_DIRS is profile-relative variable and since it is set, /etc/xdg will not be used as per the spec:

If $XDG_CONFIG_DIRS is either not set or empty, a value equal to /etc/xdg should be used.

We could add (pkgs.writeTextFile { name = "user-dirs.defaults"; text = "…"; destination = "/etc/xdg/user-dirs.defaults"; }) to environment.systemPackages which would add it to XDG_CONFIG_DIRS but that will conflict with the file from the preset file from the xdg-user-dirs package installed by gnome3 module.
Okay, I have came up with the following abomination to add to your configuration.nix:

  imports = [
    ({lib, pkgs, ...}: {
      environment.systemPackages = lib.mkBefore [
        (pkgs.writeTextFile {
          name = "user-dirs.defaults";
          text = ''
            XDG_DESKTOP_DIR=system/desktop
            XDG_DOWNLOAD_DIR=downloads
            XDG_TEMPLATES_DIR=system/templates
            XDG_PUBLICSHARE_DIR=system/public
            XDG_DOCUMENTS_DIR=documents
            XDG_MUSIC_DIR=media/music
            XDG_PICTURES_DIR=media/photos
            XDG_VIDEOS_DIR=media/video
          '';
          destination = "/etc/xdg/user-dirs.defaults";
        })
      ];
    })
  ];

But again, it does not work. Turns out we are prefixing the XDG_CONFIG_DIRS with presets when running xdg-user-dirs-update. So we need to patch as well.

With the patch and the horrendous snippet, I can confirm the expected directories were created.

We should try to find out how to make the environment variable contain /etc/xdg before all the profile-related stuff so that the simple solution works.

Previously, we were only adding profile-relative paths to XDG_CONFIG_DIRS variable. That required very ugly hacks like NixOS#33282 (comment) to be able to configure XDG stuff. Now, we are prepending the variable with /etc/xdg, allowing us to simply use `environment.etc."xdg/…"` options.

jtojnar · 2019-08-24T14:14:30Z

#67389 now contains full fix enabling us to use environment.etc."xdg/user-dirs.defaults".text as suggested in #33282 (comment).

dasj19 · 2019-08-24T14:46:45Z

Awesome @jtojnnar .... I just built from your branch https://github.com/jtojnar/nixpkgs/tree/xdg-user-dirs and works like a charm.
Thanks a lot, I owe you one

The config I'm currently using after the developments in #67389 is...

  environment.etc."xdg/user-dirs.defaults".text = ''
    DESKTOP=system/desktop
    DOWNLOAD=downloads
    TEMPLATES=system/templates
    PUBLICSHARE=system/public
    DOCUMENTS=documents
    MUSIC=media/music
    PICTURES=media/photos
    VIDEOS=media/video
  '';

@jtojnar @tiramiseb you probably want to reopen this, because functionality implemented here is currently broken.

Please see: #221604

jtojnar · 2023-03-24T15:32:22Z

As mentioned in the other issue, there is a prerequisite of environment.systemPackage = [ pkgs.xdg-user-dirs ] and having something that runs autostart entries (which DEs like GNOME or Plasma do out of the box).
