Ruby bindings to control windows in EWMH and NetWM compatible X Window manager.
ruby-wmctrl is a C extended library, which uses glib and x11, and is not a program to parse the output of command "wmctrl".
On ubuntu 11.04, we should install the following packages.
apt-get install libx11-dev libglib2.0-dev libxmu-dev
Then we can install ruby-wmctrl from rubygems.
gem install ruby-wmctrl
Note that values of positions of windows aredifferent from those of original "wmctrl" and include frame sizes.
We load 'wmctrl' as below;
We get desktops and windows as follows;
pp WMCtrl.instance.desktops pp WMCtrl.instance.windows
We can specify search conditions of windows; for example,
pp WMCtrl.instance.windows(:wm_class => /^emacs/)
ruby-wmctrl has some basic methods derived from wmctrl, but the author think that these methods may be changed in future release.
require 'wmctrl' require 'pp' wm = WMCtrl.instance pp wm.list_windows
If you want to get properties of windows, you pass true as an argument.
The method 'action_window' takes window ID as first argument. We can get window ID by the method 'list_windows'. The second argument of 'action_window' is an action that manages the window of window ID. The rest arguments are arguments of the action.
wm.action_window(window_id, :move_resize, 0, 100, 200, 500, 400)
The integers of the arguments means gravity, x coordinate, y coordinate, width, and height, respectively. That is,
wm.action_window(window_id, :move_resize, gravity, x, y, width, height)
wm.action_window(window_id, :move_to_desktop, desktop_id)
ruby-wmctrl includes the command "rwmctrl", which imitates the command "wmctrl" but does not implement all functionalities of "wmctrl".
ruby-wmctrl is created from source code of wmctrl http://sweb.cz/tripie/utils/wmctrl/.
