The plugin is a straightforward light/dark theme switcher that runs gsettings and omarchy theme commands with user permissions, with no network access, persistence, or privilege escalation. The deterministic scan found no issues, and the code is transparent and well-documented.

  • The plugin executes shell commands via bash -lc, but the commands are constructed from fixed strings and user-selected theme names that are shell-quoted, so injection risk is minimal.
  • The plugin runs a long-lived gsettings monitor and a 60-second timer, which are expected for its functionality and stop when the shell exits.
  • Theme names from `omarchy theme list` are sanitized to prevent rich-text injection in the UI, showing good security awareness.
How this check works

This review combines the deterministic scan (the rule-based results above) with an independent look at the plugin's code by a language model. The model reads a trimmed sample of the repository's files, the manifest, and the README, then gives a plain-language risk level and a recommendation: install (no notable danger), review (look closer first), or avoid (clearly dangerous).

It runs on the same analyzed commit as the deterministic scan and is strictly advisory — it is not a security guarantee and never blocks a plugin by itself. A human moderator still reviews plugins before they are listed.

Install

Appearance #bar #quickshell #system

Omamode

An Omarchy shell (Quickshell) plugin that keeps GNOME's light/dark preference and your Omarchy theme in sync. Set a default theme for light mode and one for dark mode; flip between them with two buttons, let GNOME's own setting drive it, or put it on a daily schedule — either way, your Omarchy theme follows automatically.

  • Manual switch — Light/Dark buttons in the bar dropdown.
  • Follows GNOME — if org.gnome.desktop.interface color-scheme changes from anywhere else (GNOME Settings, another script), the Omarchy theme switches to match.
  • Scheduled — optional daily light/dark times; a manual switch while the schedule is on overrides it only until the next scheduled boundary, then the schedule resumes.

Omamode dropdown

Installation

omarchy plugin add https://github.com/andrewmsboyd/omamode.git --enable

This adds the widget to your bar's right section. Move it with:

omarchy bar move io.github.andrewmsboyd.omamode --section right

Usage

Click the dimmer-switch icon in the bar to open the dropdown:

  1. Light / Dark buttons — switch immediately.
  2. Light theme / Dark theme — pick the Omarchy theme each mode should apply (any theme omarchy theme list shows).
  3. Automatic schedule — toggle on, then set the hour/minute each mode should start.

The status line at the top of the dropdown shows the current mode and either "following schedule" or how long a manual override has left before the schedule resumes.

CLI / keybinding access

omarchy-shell omamode status   # {"mode":"light","scheduleEnabled":true,"overrideActive":false}
omarchy-shell omamode light    # switch to light
omarchy-shell omamode dark     # switch to dark
omarchy-shell omamode toggle   # flip mode

Useful for wiring a Hyprland keybinding if you don't want to open the dropdown.

Configuration

All configuration is stored inline in the widget's own entry in ~/.config/omarchy/shell.json (the same mechanism Omarchy's built-in widgets use for their settings) — there's no separate config file. Everything is editable from the dropdown; the underlying keys are lightTheme, darkTheme, scheduleEnabled, scheduleLightTime, scheduleDarkTime.

How it works / dependencies

  • Runs entirely inside the existing omarchy-shell process — like every Omarchy shell plugin, it is not sandboxed and runs with your user permissions. It does not start a second Quickshell process, install a systemd service, or require any daemon of its own.
  • Requires the gsettings binary (part of glib2) and the omarchy CLI, both already present on a standard Omarchy install. No packages are installed by this plugin.
  • Two background processes are owned by the plugin's own service for as long as omarchy-shell runs: a gsettings monitor subprocess (detects external color-scheme changes) and a 60-second internal timer (evaluates the schedule). Both stop when the shell does; nothing persists outside it.
  • The only commands it ever runs are gsettings get/set/monitor org.gnome.desktop.interface color-scheme and omarchy theme list/current/set — no sudo, no privilege escalation, no network access.

Removal

omarchy plugin remove io.github.andrewmsboyd.omamode

Attribution

The bulk of this plugin's design and implementation — architecture, Service/ BarWidget code, the icon-contrast fix, marketplace packaging — was written by Claude (Anthropic), working interactively with @andrewmsboyd, who directed the design, tested it on real hardware, and reviewed/approved every change. Noted here for transparency since GitHub's Contributors graph only credits identities tied to a real linked account, which doesn't exist for an AI assistant working locally.
