This is an auto tiler for the GlazeWM window manager. It is written in Rust which allows for easy and portable compilation.

Any time a window is focused, the tiling direction of the window will be set that a new window will be placed in the direction with the highest length.

Initial state:
A new window (C) is about to be placed. The tiling direction depends on the focused window.

A focused window is denoted by an asterisk (*).

    -----------------------
    |                     |
    |                     |
    |      a       B*     |  <- Suppose B is focused
    |                     |
    |                     |
    -----------------------

Since B is focused, the longest direction from B’s perspective is vertical, so C is placed below B:

    -----------------------
    |          |          |  
    |          |    b     |  
    |      a   |----------|  
    |          |    C*    |  <- C is placed below B
    |          |          |
    -----------------------
    
Now with C focused, the longest direction from C’s perspective is horizontal, so D is placed to the right of C:

    -----------------------
    |          |          |  
    |          |    b     |  
    |      a   |----------|  
    |          | c  |  D* |  <- D is placed to the right of C
    |          |    |     |
    -----------------------

It is a fork of the archived GAT-GWM project by ParasiteDelta, but has mostly been rewritten.

• Rust (Can be installed with rustup)

cargo install --git https://github.com/Dutch-Raptor/GAT-GWM.git --features=no_console

If ~/.cargo/bin is in your PATH, you can run gat-gwm from anywhere.

git clone https://github.com/glzr-io/gat-gwm
cd gat-gwm
cargo build --release --features=no_console

The executable will be in target/release/gat-gwm.

1. Open your GlazeWM config file (usually ~/.glzr/glazewm/config.yaml).

2. Add the following command to your general::startup_commands list:

   shell-exec gat-gwm

   Example:

   general:
       # Commands to run when the WM has started (e.g. to run a script or launch
       # another application). Here we are running a batch script to start Zebar.
       startup_commands: ['shell-exec zebar', 'shell-exec gat-gwm']

• Does not support resizing of windows. I am not aware of a way to get notified when a window is resized by GlazeWM. As a workaround, you can refocus the window after it has been resized or manually set the tiling direction.
