Hello xmonad world.
My current desktop setup includes remote control unit, which sends
keyboard events (for example, it sends Ctrl-P on Pause button). I want
to handle such keypresses differently than keypresses from usual
keyboard. For example, currently, if I press Ctrl-P on keyboard or Pause
on the remote control, when Firefox window is active, both actions open
Print dialog. But I want to run, for example, "mpc pause" on Pause button.
AFAIK, one way to differ key/button press events from different devices
is to use XInput X11 extension. That extension might allow us to do many
other funny things; for example, we could get pressure value from wacom
tablets, and so on.
Technically, XInput support for XMonad will require FFI bindings to
XInput client library (-lXi) and changes in events processing in xmonad
core. Maybe, there should be new field in XMonad config, in addition to
`keys' and `mouseBindings', to specify XInput events handlers.
Currently i'm working on xinput FFI bindings.
* Could such changes in xmonad core events processing be accepted for
xmonad-core? Note that they will introduce new system library dependency
(-lXi in addition to existing -lX11).
* What features of XInput might be useful for XMonad? For example, I
don't know what to do with pressure value in window manager, but maybe
Any other thoughts are welcome too.
With best regards,
