Repeatedly press one of the defined keybindings to cycle through window sizes available at the desired location on the screen.

Configuration is done via a JSON file located at ~/.config/pygrid.json which will be created with default options if not found when starting up. The default configuration is below. If you introduce top level sections 'monitor0': {...} or 'monitor1': {...} to provide different options for each monitor on your system. Any settings not defined will fall back to user-defined defaults, then global defaults. NOTE: Updating configuration in this JSON file does not require you to restart PyGrid.

{
  'default': {
    'xdivs': 3,               // number of x divisions for the screen.
    'ydivs': 2,               // number of y divisions for the screen.
    'padding': [0, 0, 0, 0],  // additional top, right, bottom, left padding in pixels.
    'spacing': 4,             // spacing between windows in pixels.
    'minwidth': 0.25,         // min percent width of window.
    'maxwidth': 0.67,         // max percent width of window.
    'minheight': 0.33,        // min percent height of window.
    'maxheight': 0.67,        // max percent height of window.
  },
  'monitor0': { ... },        // Repeat any settings above specific for monitor 0.
  'monitor1': { ... },        // Repeat any settings above specific for monitor 1.
  'monitor<NUM>': { ... },    // Repeat any settings above specific for monitor <NUM>.

$ sudo apt-get install git python3-gi python3-xlib
$ cd <place-you-want-to-store-pygrid>

$ cd pygrid && ./pygrid.py

To start at boot I simply added the following line to Startup Applications.

PyGrid was original a fork of QuickTile by ssokolow, but rewritten to allow a much easier configuration as well as updated code to run on Python3 & GTK3. Code released under GPLv2 License.
