Omarchy

ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

omarchy default editor <gui-editor> does not update XDG MIME defaults, so GUI-opened files still launch nvimrevision 1 · captured 2026-10-04 12:03 UTC via poll

What happened

After running omarchy default editor code, files opened via the file manager / xdg-open still open in nvim. Omarchy's own launcher (omarchy-launch-editor, $EDITOR, keybindings) correctly opens VSCode, so the setting appears to work — but anything routed through the XDG MIME database ignores it.

Expected behavior

Setting a default editor should make text files open in that editor regardless of how they're opened (terminal and GUI/xdg-open).

Steps to reproduce

  1. On a fresh Omarchy install (nvim is fallback default): omarchy default editor code
  2. Verify Omarchy's state is correct: cat ~/.local/state/omarchy/defaults/editor → code
  3. Check the XDG layer: xdg-mime query default text/plain → nvim.desktop
  4. Open any .txt from the file manager → opens in nvim in a terminal

Root cause

  • /usr/bin/omarchy-default-editor only writes ~/.local/state/omarchy/defaults/editor; it never touches mimeapps.list
  • User's ~/.config/mimeapps.list has no text/plain entry, so XDG falls back to scanning .desktop claims
  • Arch's code.desktop declares only application/x-code-workspace (no text/* types), while nvim.desktop declares a broad list of text/* types — so nvim wins the fallback for all text files
  • omarchy-launch-editor correctly reads the state file (falls back to nvim only when absent), which masks the problem for terminal-side editing

Proposed fix

In omarchy-default-editor, after writing the state file, also set the XDG default by resolving each editor's desktop file, e.g.:

case "$editor" in
code)         desktop="code.desktop" ;;
cursor)       desktop="cursor.desktop" ;;
zed)          desktop="dev.zed.Zed.desktop" ;;
sublime_text) desktop="sublime_text.desktop" ;;
helix)        desktop="helix.desktop" ;;
vim|emacs|nvim) desktop="$editor.desktop" ;;
esac

if find ~/.local/share/applications /usr/share/applications -maxdepth 1 -name "$desktop" | grep -q .; then
  xdg-mime default "$desktop" \
    text/plain application/json application/x-shellscript \
    text/markdown text/x-yaml text/x-toml
fi

Secondary consideration: upstream VS Code's .desktop ships without text/* MimeType entries. omarchy refresh applications (or a shipped launcher override) could install a corrected code.desktop so VSCode shows up as an "Open With…" candidate too.

## What happened

After running `omarchy default editor code`, files opened via the file manager / `xdg-open` still open in nvim. Omarchy's own launcher (`omarchy-launch-editor`, `$EDITOR`, keybindings) correctly opens VSCode, so the setting appears to work — but anything routed through the XDG MIME database ignores it.

## Expected behavior

Setting a default editor should make text files open in that editor regardless of how they're opened (terminal *and* GUI/xdg-open).

## Steps to reproduce

1. On a fresh Omarchy install (nvim is fallback default): `omarchy default editor code`
2. Verify Omarchy's state is correct: `cat ~/.local/state/omarchy/defaults/editor` → `code`
3. Check the XDG layer: `xdg-mime query default text/plain` → `nvim.desktop`
4. Open any `.txt` from the file manager → opens in nvim in a terminal

## Root cause

- `/usr/bin/omarchy-default-editor` only writes `~/.local/state/omarchy/defaults/editor`; it never touches `mimeapps.list`
- User's `~/.config/mimeapps.list` has no `text/plain` entry, so XDG falls back to scanning `.desktop` claims
- Arch's `code.desktop` declares only `application/x-code-workspace` (no `text/*` types), while `nvim.desktop` declares a broad list of `text/*` types — so nvim wins the fallback for all text files
- `omarchy-launch-editor` correctly reads the state file (falls back to `nvim` only when absent), which masks the problem for terminal-side editing

## Proposed fix

In `omarchy-default-editor`, after writing the state file, also set the XDG default by resolving each editor's desktop file, e.g.:

```bash
case "$editor" in
code)         desktop="code.desktop" ;;
cursor)       desktop="cursor.desktop" ;;
zed)          desktop="dev.zed.Zed.desktop" ;;
sublime_text) desktop="sublime_text.desktop" ;;
helix)        desktop="helix.desktop" ;;
vim|emacs|nvim) desktop="$editor.desktop" ;;
esac

if find ~/.local/share/applications /usr/share/applications -maxdepth 1 -name "$desktop" | grep -q .; then
  xdg-mime default "$desktop" \
    text/plain application/json application/x-shellscript \
    text/markdown text/x-yaml text/x-toml
fi
```

Secondary consideration: upstream VS Code's `.desktop` ships without `text/*` MimeType entries. `omarchy refresh applications` (or a shipped launcher override) could install a corrected `code.desktop` so VSCode shows up as an "Open With…" candidate too.
