hy3

i3 / sway like layout for hyprland.

Features

i3 like tiling
Node based window manipulation (you can interact with multiple windows at once)
Greatly improved tabbed node groups over base hyprland
Optional autotiling

Additional features may be suggested in the repo issues or the matrix room.

Stability

hy3 always tracks the latest (git) version of hyprland. It likely will not work when built against a given stable hyprland release, however it will probably work within a few commits of the latest hyprland version. Please ping @outfoxxed:outfoxxed.me in the matrix room or make an issue if hy3 does not build or function against the latest hyprland commit.

Commits are tested for obvious crashes before pushing and usually fine, however you may occasionally find a bug.

If you encounter any bugs, please report them in the issue tracker.

When reporting bugs, please include:

Commit hash of the version you are running.
Steps to reproduce the bug (if you can figure them out)
backtrace of the crash (if applicable)

If you are too lazy to use the issue tracker, please at least ping @outfoxxed:outfoxxed.me in the matrix room with your bug information.

Installation

Nix

Hyprland home manager module

Assuming you use hyprland's home manager module, you can easily integrate hy3 by adding it to the plugins array.

# flake.nix

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };

    hyprland.url = "github:hyprwm/Hyprland";

    hy3 = {
      url = "github:outfoxxed/hy3";
      inputs.hyprland.follows = "hyprland";
    };
  };

  outputs = { nixpkgs, home-manager, hyprland, hy3, ... }: {
    homeConfigurations."user@hostname" = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.x86_64-linux;

      modules = [
        hyprland.homeManagerModules.default

        {
          wayland.windowManager.hyprland = {
            enable = true;
            plugins = [ hy3.packages.x86_64-linux.hy3 ];
          };
        }
      ];
    };
  };
}

Manual (Nix)

hy3's binary is availible as ${hy3.packages.<system>.hy3}/lib/libhy3.so, so you can also directly use it in your hyprland config like so:

# ...
wayland.windowManager.hyprland = {
  # ...
  extraConfig = ''
    plugin = ${hy3.packages.x86_64-linux.hy3}/lib/libhy3.so
  '';
};

Arch (AUR)

There is an unofficial hy3-git package, usable with the hyprland-git package.

Manual

Install hyprland, including its headers and pkg-config file, then run the following commands:

cmake -DCMAKE_BUILD_TYPE=Debug -B build
cmake --build build

The plugin will be located at build/libhy3.so, and you can load it normally (See the hyprland wiki for details.)

Note that the hyprland headers and pkg-config file MUST be installed correctly, for the target version of hyprland.

Configuration

Set your general:layout to hy3 in hyprland.conf.

hy3 requires using a few custom dispatchers for normal operation. In your hyprland config replace the following dispatchers:

movefocus -> hy3:movefocus
movewindow -> hy3:movewindow

You can use hy3:makegroup to create a new split.

The dispatcher list and config fields sections have all the configuration options, and some explanation as to what they do. The hyprland config in my dots can also be used as a reference.

Dispatcher list

hy3:makegroup, <h | v | opposite | tab>, [ephemeral | force_ephemeral] - make a vertical / horizontal split or tab group
- ephemeral - the group will be removed once it contains only one node. does not affect existing groups.
- force_ephemeral - same as ephemeral, but converts existing single windows groups.
hy3:changegroup, <h | v | tab | untab | toggletab | opposite> - change the group the node belongs to, to a different layout
- untab will untab the group if it was previously tabbed
- toggletab will untab if group is tabbed, and tab if group is untabbed
- opposite will toggle between horizontal and vertical layouts if the group is not tabbed.
hy3:setephemeral, <true | false> - change the ephemerality of the group the node belongs to
hy3:movefocus, <l | u | d | r | left | down | up | right>, [visible] - move the focus left, up, down, or right
- visible - only move between visible nodes, not hidden tabs
hy3:movewindow, <l | u | d | r | left | down | up | right>, [once], [visible] - move a window left, up, down, or right
- once - only move directly to the neighboring group, without moving into any of its subgroups
- visible - only move between visible nodes, not hidden tabs
hy3:killactive - close all windows in the focused node
hy3:changefocus, <top | bottom | raise | lower | tab | tabnode>
- top - focus all nodes in the workspace
- bottom - focus the single root selection window
- raise - raise focus one level
- lower - lower focus one level
- tab - raise focus to the nearest tab
- tabnode - raise focus to the nearest node under the tab
hy3:focustab <mouse | [l | r | left | right | index, <index>], [prioritize_hovered | require_hovered], [wrap]>
- mouse - focus the tab under the mouse, works well with a non consuming bind, e.g.
```
# binds hy3:focustab to lmb and still allows windows to receive clicks
bindn = , mouse:272, hy3:focustab, mouse
```
- l | r | left | right - direction to change focus towards
- index, <index> - select the indexth tab
- prioritize_hovered - prioritize the tab group under the mouse when multiple are stacked. use the lowest group if none is under the mouse.
- require_hovered - affect the tab group under the mouse. do nothing if none are hovered.
- wrap - wrap to the opposite size of the tab bar if moving off the end
hy3:debugnodes - print the node tree into the hyprland log
⚠️ ALPHA QUALITY hy3:setswallow, <true | false | toggle> - set the containing node's window swallow state
⚠️ ALPHA QUALITY hy3:expand, <expand | shrink | base> - expand the current node to cover other nodes
- expand - expand by one node
- shrink - shrink by one node
- base - undo all expansions
