Cobble Bar Widgets

This repository contains widgets that I use with eww on my Hyprland-based desktop:

  • cobble-clock: Tracks the system time in a power-efficient fashion by sleeping between updates, only waking once per minute (on the minute) to update the widget state.
  • cobble-audio: Listens for Wireplumber events to keep track of the volume of the default audio sink.
  • cobble-network: Listens for changes in the state of network interfaces and wireless devices to track the connection state of the machine.
  • cobble-workspaces: Listens for events from Hyprland to track changes in the state of Hyprland workspaces.

The goal for these widgets to be as power-efficient as possible. In this case, that means reasonably small memory footprints, providing interfaces compatible with eww's deflisten widget mechanism and sleeping as much as possible.

As a consequence of needing to communicate directly with Wireplumber, this repository also contains safe bindings for libwireplumber-0.5.

Building

First, generate the unsafe bindings for libwireplumber-0.5 using gir. Then build cobble-bar as normal:

$ (cd wireplumber-sys && gir -o .)
$ (cd cobble-bar && cargo build)
