[BUG]

[ReEloy228]

Step 1. Before you submit

• I have read the above instructions and am sure that this is supposed to be posted here.
• I've successfully updated to the latest versions following the updating guide.
• I've successfully updated the system packages to the latest.
• I've ticked the checkboxes without reading their contents

Step 2. Version info

Version info

Packages: not on Arch

fatal: не является репозиторием git: «/home/eloy/.config/.git»
Caelestia: not installed

Shell: version helper not available

Quickshell: not in PATH

Step 3. Describe the issue

Describe the bug
On NixOS with the latest caelestia-shell (using the HM module), no color schemes are available out of the box. The launcher shows no schemes, the schemes list is empty, and both static and dynamic schemes fail. Trying to set a scheme via CLI or apply a wallpaper results in a KeyError: 'name' traceback.
Additionally, the default shell.json managed by Home Manager is a read-only symlink, which prevents Caelestia from saving any changes.

Expected behavior

• Pre-installed schemes (like the default dynamic generator and some bundled themes) should be present and selectable.
• caelestia scheme set -n dynamic should work.
• caelestia wallpaper -p <path> should apply the wallpaper and generate a dynamic scheme.

Workaround for read-only shell.json
I worked around the read-only config by creating a mutable shell.json via mkOutOfStoreSymlink:

caelestiaConfigDir = "${config.home.homeDirectory}/dotfiles/config/caelestia";
initialShellJson = builtins.toJSON { ... };
home.activation.setupCaelestiaConfig = lib.hm.dag.entryAfter [ "writeBoundary" ] ''
    mkdir -p "${caelestiaConfigDir}"
    if [ ! -f "${caelestiaConfigDir}/shell.json" ]; then
      echo '${initialShellJson}' > "${caelestiaConfigDir}/shell.json"
      chmod 644 "${caelestiaConfigDir}/shell.json"
    fi
  '';
home.file."caelestia/shell.json" = {
    source = config.lib.file.mkOutOfStoreSymlink "${caelestiaConfigDir}/shell.json";
    force = true;
};
