Tiling and simultaneous resizing of side-by-side windows for Xfce.

Purpose
A Python script to auto-tile and to simultaneously resize docked windows.

Features:
Simultaneous resizing of adjacent windows 5 different tilers Hotkeys for:

Tiling and/or simultaneous resizing can be enabled/disabled
Tiling can be triggered manually on demand
Changing tiler
Storing and re-creating current windows layout
Cycling windows
Swap windows
Set/unset window decoration All settings are workspace specific. So for each workspace you can choose independently, if tiling is enabled and which tiler should be used. No limit of supported workspaces Config-file Pure Python, easily hackable
Hotkeys
Hotkeys can be defined in the config-file. Most important hotkeys (full set see config-file):
Super_L - 1 tiler - master and stack vertically
Super_L - 2 tiler - vertically
Super_L - 3 tiler - master and stack horizontally
Super_L - 4 tiler - horizontally
Super_L - 0 tiler - maximize
Super_L - c cycle tiler
Super_L - 5 restore windows layout
Super_L - 6 store windows layout
Super_L - ^ cycle windows
Super_L - ESC swap current window with top/left-most window
Super_L - q toggle simultaneous resizing (on/off)
Super_L - w toggle tiling (on/off)
Super_L - y toggle window-decoration (on/off) of tiled windows
Super_L - a shrink width/height of master window
Super_L - s enlarge width/height of master window
Super_L - . log name & tile of active window in /tmp/xpytile_.log
Super_L - - exit

Configuration
Well, edit the hopefully self-explanatory config-file xpytile.conf

Installation
Download from https://github.com/jaywilkas/xpytile
Place xpytilerc in XDG_CONFIG_HOME in ~/.config/ or in /etc/ respectively
ArchLinux - users can install xpytile-git from the AUR ( pacman -S xpytile.git )

Start
./xpytile.py or, to let run in background: nohup ./xpytile.py > /dev/null 2>&1 &

You may want to assign a hotkey. In Xfce for example, add a shortcut to xpytile.py with Xfce-Menu -> Settings -> Keyboard -> Application Shortcuts

Dependencies
notify-send (package: notifylib for ArchLinux, notifylib-bin for Debian/Ubuntu) python3, python-xlib

Bugs
I'm currently not aware of a bug.
When the program crashes, it writes traceback info in /tmp/xpytile_USERNAME.log

Questions
(Q) Are gaps supported?
(A) Nope

(Q) Does xpytile support multiple monitor setups?
(A) On workspaces that span multiple monitors, simultaneous resizing works fine, tiling not really.

(Q) How do I get the exact name and title of a window I want xpytile to ignore?
(A) Run xpyile with -v or -vv or use the hotkey to log name and title of the current window.
