The hacker-friendly status_command for Sway and i3
i3blocks is a feed generator for text based status bars. It executes your command lines and generates a status line from their output. Commands are scheduled at configured time intervals, upon signal reception or on clicks.
Sway is a tiling Wayland compositor and a drop-in replacement for the i3 window manager for X11. It works with your existing i3 configuration and supports most of i3's features, plus a few extras.
