Possible FVWM extensions

A window manager proper may perform many things, but what if some dynamical stuff is needed? There are 2 possible ways to write Perl utilities to extend FVWM:
  • Scripts printing a configuration in the syntax understandable by FVWM that is piped in to create menus/panels/forms. Such scripts only work on external things like files on the disk, pages on the web or the system state.
  • Window manager modules (plugins) that work on internal things, like a list of all windows and their geometries/names, changes of virtual desktops/pages, keeping a track of window operations and more.

The screenshots used in these slides are done in FVWM Themes that is by itself an FVWM extension framework written in Perl.
