From the author’s site: “A window-matching utility, inspired by Sawfish’s “Matched Windows” option and the lack of the functionality in Metacity. Metacity lacking window matching is not a bad thing — Metacity is a lean window manager, and window matching does not have to be a window manager task. ”
Installing devil’s pie is simple:
sudo apt-get install devilspie
After it is installed, we need to create the configuration directory .devilspie in the home directory, and then can proceed to the configuration. You can create either one big configuration file or many small. It’s easier for me to create many small, each one with the program name it handles. Config files must have ds extension.
opera.ds:
(if
(is (application_name) "Opera")
(begin
(set_viewport 2)
)
)
This moves the Opera window to the workspace 2. With the compiz configured, function set_workspace doesn’t work and gives error, so set_viewport should be used instead.
skype.ds:
(if
(and
(matches (application_name) "^Skype")
(not (contains (window_name) "Chat"))
)
(maximize_vertically)
)
The syntax is very simple and intuitive. To find information like application name, window class about the certain program, just create the file debug.ds with (debug) in it, and run devilspie from the console. To run devil’s pie at system startup, go to System -> Preferences -> Sessions, click Add and in the Name field write “Devils Pie” and in the Command field write “devilspie”.
