This script uses the i3ipc Rust library to switch the layout splith / splitv depending on the currently focused window dimensions.
This script is almost a direct port of https://github.com/nwg-piotr/autotiling from Python to Rust.
Run the following commands:
$ git clone https://github.com/timothyjin/autotiling
$ cd autotiling
$ cargo build --release
The built binary will be in target/release/autotiling. Place this file anywhere and autostart it by putting exec_always --no-startup-id /path/to/the/script/autotiling & in your i3 config.
