Overview
Omarchy's floating parts are flat see-through rectangles over a blur. Hyprland can blur what is behind a surface, but it cannot bend it: no refraction, no lit edge, nothing that reads as glass. Vetro makes them glass. Each pane bends the light at its edge, lights a rim that follows its own corners and frosts what is behind it.
It lies over your theme instead of replacing it, and vetro off gives you Omarchy back as it was.
What turns to glass
The bar, with every one of Omarchy's own widgets and a workspace selector that glides from number to number as a drop of glass. The menu and app launcher. The calendar and the other panels. Notifications, served by Vetro's own daemon. The volume display, the lock screen, and see-through windows such as the terminal.
Genie, jelly and wobble animations are there to switch on, and the Vetro Glass app tunes all of it by hand, with presets.
How it is built
The glass is drawn by a Hyprland plugin, a fork of hyprglass, with its shading, tuning and motion in Rust and its hooks into Hyprland in C++. The rest is a set of Omarchy shell plugins, which began with HyprPerks.
Keeping a plugin from taking the desktop down
A compositor plugin runs inside the compositor, so most of the work is in what happens when something does not line up:
- A plugin has to match its compositor exactly. A list of pins says which engine commit is built for which Hyprland, and a pin is added only once that pair has been built and seen working.
- The engine is loaded from outside, never by Hyprland's config. Hyprland reads its config again each time a plugin loads, so a config that loads one loops and freezes the screen.
- The glass is optional at every step. With no engine, an engine built for another Hyprland, or one that refuses its settings, every pane has plain blur and nothing errors.
