Usage: gosnap [-L | -l | -R | -r | -M | -m | -N | -n | -d | -i]
  -L    snap left
  -l    snap left dynamically
  -R    snap right
  -r    snap right dynamically
  -M    maximize window
  -m    toggle maximize window
  -N    minimize window
  -n    minimize window dynamically
  -d    resize to default geometry (current default: 0,10,60,826,556)
  -i    print window information

  3 # GOSNAP: Good Old Snap
  4 #
  5 # Script to emulate the Aero Snap feature in Windows 7
  6 #   Use -L or -R flags to snap left or right
  7 #   Use -l or -r flags to snap dynamically (intermediate default position)
  8 #   Use -M flag  to maximize
  9 #   Use -m flag to toggle maximized state
 10 #   Use -N flag to minimize
 11 #   Use -n flag to minimize dynamically (intermediate default position)
 12 #   Use -d flag to reset the window state to default
 13 #   Use -i flag to print window info to stdout
 14 #
 15 # wmctrl -e g,x,y,w,h (any value set to -1 won't be changed)
 16 #   g = window gravity (just set to 0)
 17 #   x = window x position
 18 #   y = window y position
 19 #   w = window width
 20 #   h = window height

 30 # The x position reported by xdotool when the window is snapped left/right.
 31 #   For some reason, snapping the window to 0,0 does not actually register as 0,0.
 32 #   Use the -i flag while the terminal window is snapped to the left or the right
 33 #   to get the values unique to your screen.
 34 left_origin_x=10
 35 right_origin_x=692

 38 #   If you see gaps on the left or right wien you snap, you may need to adjust this.

 48 # Use wmctrl bug avoidance
 49 #   For some reason, wmctrl intermittently snaps to the wrong position.
 50 #   Doing "snap_default && snap_maximize" before snapping left/right seems to fix it.
 51 #   The trade-off using this fix is that snapping left/right has a very slight delay.
