NAME

6       xkbevd - XKB event daemon
7

SYNOPSIS

9       xkbevd [ options ]
10

DESCRIPTION

12       This  command  is very raw and is therefore only partially implemented;
13       we present it here as a rough prototype for developers, not as  a  gen‐
14       eral  purpose  tool  for  end  users.  Something like this might make a
15       suitable replacement for xev;  I'm not signing up, mind you,  but  it's
16       an interesting idea.
17
18       The  xkbevd  event daemon listens for specified XKB events and executes
19       requested commands if they occur.   The configuration file consists  of
20       a list of event specification/action pairs and/or variable definitions.
21
22       An event specification consists of a short XKB event name followed by a
23       string or identifier which serves as a qualifier in parentheses;  empty
24       parenthesis  indicate no qualification and serve to specify the default
25       command which is applied to events which do not match any of the  other
26       specifications.   The  interpretation  of  the qualifier depends on the
27       type of the event:  Bell events match using the name of the bell,  mes‐
28       sage  events  match  on the contents of the message string and slow key
29       events accept any of press, release,  accept,  or  reject.    No  other
30       events are currently recognized.
31
32       An  action  consists  of  an  optional  keyword followed by an optional
33       string  argument.   Currently,  xkbev  recognizes  the  actions:  none,
34       ignore, echo, printEvent, sound, and shell.  If the action is not spec‐
35       ified, the string is taken as the name of a sound  file  to  be  played
36       unless  it  begins with an exclamation point, in which case it is taken
37       as a shell command.
38
39       Variable definitions in the argument string are  expanded  with  fields
40       from  the event in question before the argument string is passed to the
41       action processor.   The general syntax for a variable is either $cP  or
42       $(str),  where c is a single character and str is a string of arbitrary
43       length.  All parameters have both single-character and long names.
44
45       The list of recognized parameters varies from event to event and is too
46       long  to  list here right now.   This is a developer release anyway, so
47       you can be expected to look at the source code (evargs.c is of particu‐
48       lar interest).
49
50       The ignore, echo, printEvent, sound,and shell actions do what you would
51       expect commands named ignore, echo, printEvent, sound, and shell to do,
52       except  that the sound command has only been implemented and tested for
53       SGI machines.   It launches an external program right now, so it should
54       be  pretty easy to adapt, especially if you like audio cues that arrive
55       about a half-second after you expect them.
56
57       The only currently recognized variables are soundDirectory  and  sound‐
58       Cmd.  I'm sure you can figure out what they do.

OPTIONS

61       -help   Prints  a  usage  message that is far more up-to-date than any‐
62               thing in this man page.
63
64       -cfg file
65               Specifies the configuration file to read.   If no configuration
66               file is specified, xkbevd looks for ~/.xkb/xkbevd.cf and $(LIB‐
67               DIR)/xkb/xkbevd.cf in that order.
68
69       -sc cmd Specifies the command used to play sounds.
70
71       -sd directory
72               Specifies a top-level directory for sound files.
73
74       -display display
75               Specifies the display to use.   If  not  present,  xkbevd  uses
76               $DISPLAY.
77
78       -bg     Tells xkbevd to fork itself (and run in the background).
79
80       -synch  Forces synchronization of all X requests.  Slow.
81
82       -v      Print  more information, including debugging messages.   Multi‐
83               ple specifications of -v cause more output, to a point.
