Xakar v5-rc1 — Native C++ X11 Tiling Daemon

First release candidate for fifth-generation tiling daemon — rewritten in optimized C with direct Xlib/Xinerama calls.
No Python, no external tools, no flicker. Fast, minimal, multi-monitor aware. No need for Xcape and added even more features, also needs installing .config at $HOME/.setuzuna/xakar/.config

---

What's New in v4

• Pure C++17 implementation — replaces the Python daemon from v3.x
• Direct Xlib/Xinerama — zero dependencies beyond libX11 and libXinerama
• Multi-monitor smart tiling:
  • Detects the monitor of the active window
  • Moves windows across monitors with preserved geometry or preserved size
  • Neighbor monitor detection (left/right/up/down aware)
• New commands:
  • preserve_geom <dir> → Move to another monitor, keep window position & size if possible
  • preserve_size <dir> → Move to another monitor, preserve size, reapply tiling mode
  • wm_fullscreen → Toggle WM-managed fullscreen (uses _NET_WM_STATE_FULLSCREEN)
• KHotKeys integration — automatic shortcut setup with config.py
• Autostart support — installs .desktop files into TDE's autostart folder

What's New in v4.1

• Now with completely automatic uninstaller

---

Installation

1. Install build dependencies

sudo apt update
sudo apt install -y build-essential libx11-dev libxinerama-dev

2. Clone and build

git clone https://codeberg.org/Setuzuna/Xakar.git
cd Xakar
make

3. Install

make install

This will:

• Install the binary xakard into /usr/local/bin

• Generate KHotKeys bindings (~/.trinity/share/apps/khotkeys/setuzuna_xakar.khotkeys)

• Create autostart entries for:

  • xakard (the tiling daemon)
  • xcape (optional Win key rebind)

4. Uninstall

make uninstall

This will remove:

• /usr/local/bin/xakard
• Autostart .desktop entries
• Custom KHotKeys config (setuzuna_xakar)

---

Usage

Run manually:

xakard

It listens on:

$HOME/.xakar.sock

Send actions to it with:

echo left > ~/.xakar.sock
echo fullscreen > ~/.xakar.sock
echo preserve_geom right > ~/.xakar.sock

---

Default Keybindings (via KHotKeys)

Installed automatically by config.py.

Keys	Action
Win+Up	up (top half / quarter)
Win+Down	down (bottom half / quarter)
Win+Left	left (left half / quarter)
Win+Right	right (right half / quarter)
Win+Return	center (3/4 centered)
Win+Space	fullscreen (fill monitor)
Win+Shift+Space	wm_fullscreen (toggle WM fullscreen)
Win+Alt+[Arrows]	preserve_geom move to neighbor monitor preserving geometry
Win+Ctrl+[Arrows]	preserve_size move to neighbor monitor perserving tile mode

---

Example: Multi-monitor workflow

• Win+Left → Snap active window to left half of current monitor
• Press again → Push to the right half of neighbor monitor
• Win+Alt+Right → Move window to right monitor, preserving geometry
• Win+Ctrl+Right → Move window to right monitor, preserving size
