Sikiri

A fork of niri, with Hyprland-style horizontal splitting functionality added.

日本語版README

Overview

Sikiri arranges windows in a single row on an infinitely extending strip to the right. Opening a new window does not resize existing windows.

Key Features:

• Independent strips per monitor: Each monitor has its own window strip. Windows do not spill over onto adjacent monitors.
• Dynamic workspaces: Workspaces are arranged vertically and dynamically. Each monitor has its own set of workspaces, with one empty workspace always available at the bottom.
• Smart workspace preservation: Workspace layouts are preserved as much as possible when monitors are disconnected or reconnected. When a monitor disconnects, its workspaces move to another monitor and return to the original monitor upon reconnection.
• Horizontal splitting: The added horizontal splitting feature assists window movement. niri's original scrollable tiling remains fully usable.

Inspiration

This project was strongly influenced by its forked source, niri, and traditional tiling window managers like Hyprland.

Special thanks to i3wm for introducing me to the world of window managers, and to niri for providing an excellent foundation.
