wmfocus - Visually focus windows by label

CI AUR Crates.io license Stars Lines of Code

This tool that allows you to rapidly choose a specific window directly without having to use the mouse or directional keyboard navigation.

Screen cast

Thanks to cairo, it should work on all kinds of screens and automatically display at the correct size according to your DPI.

Installation

Packaging status

On Arch Linux: Get it from AUR

With Cargo: cargo install --features i3 wmfocus

Usage

Draw labels on the upper-left corner of all windows:

wmfocus

Completely fill out windows and draw the label in the middle (try it with transparency!):

wmfocus --fill

Use a different font (as provided by fontconfig):

wmfocus -f "Droid Sans":100

Change up the default colors:

wmfocus --textcolor red --textcoloralt "#eeeeee" --bgcolor "rgba(50, 50, 200, 0.5)"

wmfocus will make use of a compositor to get real transparency.

Troubleshooting

If there's some funky stuff, you can try to track it down by running wmfocus with RUST_LOG=trace:

RUST_LOG=trace wmfocus

This will print quite some useful debugging info.

Compiling

You need to have recent versions of rust, cargo, xcb-util-keysyms, libxkbcommon-x11 and cairo installed.

Then, just clone it like usual and cargo run to get output:

git clone https://github.com/svenstaro/wmfocus.git
cd wmfocus
cargo run --features i3

Window manager support

While this tool is window manager-independent, an implementation for your favorite window manager might not yet be available. Current support:

  • i3
  • sway (partial, accepting PRs)

If you want to implement support for more window managers, have a look at the i3 implementation.

This tool is heavily inspired by i3-easyfocus.

Releasing

This is mostly a note for me on how to release this thing:

  • cargo release --dry-run
  • cargo release
  • Release will automatically be deployed by Github Actions.
  • Update AUR package.
