A small Rust program for Waybar helpers, shared for reference purposes. It currently has one subcommand: wayeyes, which indicates via swayipc-async whether the focused node has xdgshell, xwaylandshell or something else.
Config example is included in my Dotfile-Snippets repository.
From the repository root:
# Build all crates
cargo build
# Run the binary (e.g. the 'wayeyes' subcommand)
cargo run -p waybar-helper -- wayeyes
# install the binary in $HOME/.cargo/bin
cargo install -p waybar-helper
