NAME

     xkbevd - XKB event daemon

SYNOPSIS

     xkbevd [ options ]

DESCRIPTION

     This command is very raw and is therefore only partially
     implemented;  we present it here as a rough prototype for
     developers, not as a general purpose tool for end users.
     Something like this might make a suitable replacement for
     xev;  I'm not signing up, mind you, but it's an interesting
     idea.

     The xkbevd event daemon listens for specified XKB events and
     executes requested commands if they occur.   The configura-
     tion file consists of a list of event specification/action
     pairs and/or variable definitions.

     An event specification consists of a short XKB event name
     followed by a string or identifier which serves as a qualif-
     ier in parentheses;  empty parenthesis indicate no qualifi-
     cation and serve to specify the default command which is
     applied to events which do not match any of the other
     specifications.  The interpretation of the qualifier depends
     on the type of the event:  Bell events match using the name
     of the bell, message events match on the contents of the
     message string and slow key events accept any of press,
     release, accept, or reject.   No other events are currently
     recognized.

     An action consists of an optional keyword followed by an
     optional string argument.  Currently, xkbev recognizes the
     actions: none, ignore, echo, printEvent, sound, and shell.
     If the action is not specified, the string is taken as the
     name of a sound file to be played unless it begins with an
     exclamation point, in which case it is taken as a shell com-
     mand.

     Variable definitions in the argument string are expanded
     with fields from the event in question before the argument
     string is passed to the action processor.   The general syn-
     tax for a variable is either $cP or $(str), where c is a
     single character and str is a string of arbitrary length.
     All parameters have both single-character and long names.

     The list of recognized parameters varies from event to event
     and is too long to list here right now.   This is a
     developer release anyway, so you can be expected to look at
     the source code (evargs.c is of particular interest).

     The ignore, echo, printEvent, sound,and shell actions do
     what you would expect commands named ignore, echo, prin-
     tEvent, sound, and shell to do, except that the sound com-
     mand has only been implemented and tested for SGI machines.
     It launches an external program right now, so it should be
     pretty easy to adapt, especially if you like audio cues that
     arrive about a half-second after you expect them.

     The only currently recognized variables are soundDirectory
     and soundCmd.  I'm sure you can figure out what they do.

OPTIONS

     -help   Prints a usage message that is far more up-to-date
             than anything in this man page.

     -cfg file
             Specifies the configuration file to read.   If no
             configuration file is specified, xkbevd looks for
             ~/.xkb/xkbevd.cf and $(LIBDIR)/xkb/xkbevd.cf in that
             order.

     -sc cmd Specifies the command used to play sounds.

     -sd directory
             Specifies a top-level directory for sound files.

     -display display
             Specifies the display to use.  If not present,
             xkbevd uses $DISPLAY.

     -bg     Tells xkbevd to fork itself (and run in the back-
             ground).

     -synch  Forces synchronization of all X requests.  Slow.

     -v      Print more information, including debugging mes-
             sages.   Multiple specifications of -v cause more
             output, to a point.
