An unoffical rust wrapper for Hyprland's IPC

Disclaimer

If something doesn't work, doesn't matter what, make sure you are on the latest commit of Hyprland before making an issue!

Getting started!

Lets get started with Hyprland-rs!

Adding to your project

Add the code below to the dependencies section of your Cargo.toml file!

hyprland = "0.3.0"

What this crate provides

This crate provides 3 modules (+1 for shared things)

• data for getting information on the compositor
• event_listener which provides the EventListener struct for listening for events
• dispatch for calling dispatchers and changing keywords

Example Usage

here is an example of most of the provided features being utilized

use hyprland::data::{Client, Clients, Monitors};
use hyprland::dispatch::*;
use hyprland::event_listener::EventListenerMutable as EventListener;
use hyprland::keyword::*;
use hyprland::prelude::*;
use hyprland::shared::WorkspaceType;

fn main() -> hyprland::shared::HResult<()> {
    // We can call dispatchers with the dispatch macro, and struct!
    // You can decide what you want to use, below are some examples of their usage

    // Here we are telling hyprland to open kitty using the dispatch macro!
    hyprland::dispatch!(Exec, "kitty")?;

    // Here we are moving the cursor to the top left corner! We can also just use the Dispatch
    // struct!
    Dispatch::call(DispatchType::MoveCursorToCorner(Corner::TopLeft))?;

    // Here we are adding a keybinding to Hyprland using the bind macro!
    hyprland::bind!(SUPER, Key, "i" => ToggleFloating, None)?;

    // Here we are getting the border size
    let border_size = match Keyword::get("general:border_size")?.value {
        OptionValue::Int(i) => i,
        _ => panic!("border size can only be a int"),
    };
    println!("{border_size}");

    // Here we change a keyword, in this case we are doubling the border size we got above
    Keyword::set("general:border_size", border_size * 2)?;

    // get all monitors
    let monitors = Monitors::get()?;

    // and the active window
    let win = Client::get_active()?;

    // and all open windows
    let clients = Clients::get()?;

    // and printing them all out!
    println!("monitors: {monitors:#?},\nactive window: {win:#?},\nclients {clients:#?}");

    // Create a event listener
    let mut event_listener = EventListener::new();

    // This changes the workspace to 5 if the workspace is switched to 9
    // this is a performance and mutable state test
    event_listener.add_workspace_change_handler(|id, state| {
        if id == WorkspaceType::Regular('9'.to_string()) {
            state.active_workspace = WorkspaceType::Regular('2'.to_string());
        }
    });
    // This makes it so you can't turn on fullscreen lol
    event_listener.add_fullscreen_state_change_handler(|fstate, state| {
        if fstate {
            state.fullscreen_state = false;
        }
    });
    // Makes a monitor unfocusable
    event_listener.add_active_monitor_change_handler(|data, state| {
        let hyprland::event_listener::MonitorEventData(monitor, _) = data;

        if monitor == *"DP-1".to_string() {
            state.active_monitor = "eDP-1".to_string()
        }
    });

    // add event, yes functions and closures both work!
    event_listener.add_workspace_change_handler(|id, _| println!("workspace changed to {id:#?}"));
    // Waybar example
    // event_listener.add_active_window_change_handler(|data| {
    //     use hyprland::event_listener::WindowEventData;
    //     let string = match data {
    //         Some(WindowEventData(class, title)) => format!("{class}: {title}"),
    //         None => "".to_string()
    //     };
    //     println!(r#"{{"text": "{string}", class: "what is this?"}}"#);
    // });

    // and execute the function
    // here we are using the blocking variant
    // but there is a async version too
    event_listener.start_listener()
}
