Moon Arc
A theme-aware lunar phase and illumination widget for the Omarchy Quattro bar. It computes the cycle locally—no location, account, API key, or network request.

Install
omarchy plugin add https://github.com/rookepoole/omarchy-moon-arc.git --enable
Click the phase mark to see the phase name, approximate illumination, lunar age, and cycle progress.
Accuracy boundary
Moon Arc uses the mean 29.53058867-day synodic cycle anchored to the known 2000-01-06 18:14 UTC new moon. It is a pleasant desktop approximation, not a full astronomical ephemeris and not suitable for navigation, tides, observation timing, or safety-critical use.
Dependencies and permissions
Requires only Omarchy Quattro and its Qt/Quickshell runtime. It makes no network requests, launches no commands, requests no privileges, and writes no files.
Remove
omarchy plugin remove io.github.rookepoole.moon-arc
