Permission denied on nix

Summary

Hello,
My problem is the following : helix need sudo access for any file, even wihout a file.
I'm on nixos and I declare my helix configuration through home-manager which create readonly configuration. On a fresh system there's no problem, but after a while, I can't use helix anymore without sudo.
I think the problem might come from readonly log. If I sudo chmod a+w ~/.cache/helix/helix.log, it works well, until nixos rebuild this file itself.
I think nixos or home-manager shouldn't touch this file ever to avoid this situation

Reproduction Steps

• Install helix through home-manager
• Use it and rebuild more than once
• problem

Helix log

There's nothing on the log, the access to the log is the problem

Platform

Linux

Terminal Emulator

Kitty

Installation Method

home-manager from nix

Helix Version

helix 24.7 (079f544)

You can create an alias where the helix is writing to /dev/null: hx --log /dev/null.

However

I'm on nixos and I declare my helix configuration through home-manager which create readonly configuration.

this doesn't sound right. I'm using helix with home-manager as well but I don't get this problem. May I ask if you could post your relevant NixOS/home-manager config here please?

That's a good work around already

{ pkgs, config, ... }:

{
  stylix.targets.helix.enable = false;

  programs.helix = {
    enable = true;
    defaultEditor = true;

    settings = {
[...]
    }
home.packages = [ pkgs.helix, ... ];
}

Hm... well that's weird that ~/.cache is just readable for you.
Maybe some other setting in your nix-config is setting this?

I have two options related to cache but I don't see how it can interfere. The first one being : home.file.".cache/ags/hyprpanel/options.json" = { used to configure hyprpanel. And the second one being programs.man.generateCaches = true; for man page with nushell

Can you share the relevant parts of your configuration? I'm running Helix on NixOS with home-manager and don't have any issues.

There's nothing more than what I posted above, so this :

{ pkgs, config, ... }:

{
  stylix.targets.helix.enable = false;

  programs.helix = {
    enable = true;
    defaultEditor = true;

    settings = {

      theme = "stylix";

...

  home.packages = with pkgs; [
    helix
...
}

I think you don't have to add helix to your packages when you set programs.helix.enable to true (I don't and it works).

I don't use stylix; have you tried disabling that?

Stylix shouldn't do anything, especially if disabled. It's pretty hard to remove since there's a lot of packages depending on it.
I will try to remove programs.helix.enable.
A theory I have, is that hyprpanel write its configuratin in ~/.cache (yes, it's very stupid), and thus make the whole directory in read-only. I will try to remove that
