i3 / sway like layout for hyprland.

Installation, Configuration

Check the changelog for a list of new features and improvements

• 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.

hy3 has a tagged release for each hyprland update, and master tracks hyprland's main branch. If you are running a release version of hyprland then use the matching tagged hy3 version. If you are running an untagged hyprland release then use the master branch of hy3.

Commits are tested before pushing and will build against the hyprland release in the flake.lock file. There may be a mismatch with hyprland's main branch. If hy3 fails to build against hyprland's main branch please make an issue or ping me in the hy3 matrix room.

Tagged hy3 versions are always checked against the corresponding hyprland tag.

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.

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 = "git+https://github.com/hyprwm/Hyprland?submodules=1&ref={version}";
    # where {version} is the hyprland release version
    # or "github:hyprwm/Hyprland?submodules=1" to follow the development branch

    hy3 = {
      url = "github:outfoxxed/hy3?ref=hl{version}"; # where {version} is the hyprland release version
      # or "github:outfoxxed/hy3" to follow the development branch.
      # (you may encounter issues if you dont do the same for hyprland)
      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 ];
          };
        }
      ];
    };
  };
}

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
  '';
};

Hyprland now has a dedicated plugin manager, which should be used when your package manager isn't capable of locking hy3 builds to the correct hyprland version.

exec-once = hyprpm reload -n

To install hy3 via hyprpm run

hyprpm add https://github.com/outfoxxed/hy3

To update hy3 (and all other plugins), run

hyprpm update

Sometimes the headers from hyprland are not updated, if this happens run (See issue #109 for an example of where this happened)

hyprpm update -f

(See the wiki for details.)

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

cmake -DCMAKE_BUILD_TYPE=Release -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.

hy3 stable (for arch's hyprland package) is availible on the AUR as hy3.

hy3-git (for hyprland-git on the AUR, unofficial package) is availible on the AUR as hy3-git.

Both packages install hy3 as /usr/lib/libhy3.so. You can enable it in your hyprland configuration by adding the following line anywhere in your hyprland.conf

plugin = /usr/lib/libhy3.so

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.

• 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], [warp | nowarp] - move the focus left, up, down, or right
  • visible - only move between visible nodes, not hidden tabs
  • warp - warp the mouse to the selected window, even if general:no_cursor_warps is true.
  • nowarp - does not warp the mouse to the selected window, even if general:no_cursor_warps is false.
• hy3:warpcursor - warp the cursor to the center of the focused node
• 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:movetoworkspace, <workspace>, [follow] - move the active node to the given workspace
  • follow - change focus to the given workspace when moving the selected node
• 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
