xtrapout [ -f script ] [ -e ] [ -d[isplay] display ] [ -v ]
xtrapin [ -f script ] [ -d[isplay] display ]
xtrapchar [ -v ] [ -d[isplay] display ]
xtrapproto [ -d[isplay] display ]
DESCRIPTION
These commands are SAMPLE CLIENTS provided with the XTrap X
Server Extension Sources, Version 3.3. XTrap is an X Server
extension which facilitates the capturing of server protocol
and synthesizing core input events. Information on how to
obtain these sources can be found in the SOURCES section
below.
The xtrapreset command is the simplest XTrap client in that
it merely performs an XQueryExtension() against XTrap. The
name "reset" is historical. The display argument is parsed
by the X Toolkit and specifies the display where XTrap is to
be loaded; see X(1).
xtrapinfo displays general configuration information as a
result of an GetAvailable XTrap request to the specified
server. It is simply designed to test the request/response
mechanism of the XTrap extension and client library as well
as display the configuration information that it finds.
xtrapstats tests the event and request vectoring of the
server extension by configuring XTrap to collect usage
statistics on all core input events and requests. It has a
primitive command-line interface for showing the counters,
zeroing out the counters, and quitting the program.
xtrapout tests the output transport from the XTrap extension
to the XTrap client library. As an aside, since xtrapout has
the capability of "recording" events and requests it
receives, xtrapout is ideal for providing input to test
xtrapin. Since events are the only concern for the input
transport, the -e flag can be specified to indicate that all
input events (and only events) should be recorded by

xtrapout. script is specified primarily for non-U*IX
machines which don't support I/O re-direction easily. The -v
flag is used to force recording of all requests and input
events.
xtrapin is used to test the input transport to the XTrap
server extension. As stated earlier, it's input can be pro-
vided by xtrapout using the -e qualifier. While it's pri-
mary function is for testing XTrap and serving as an example
for XTrap functionality, it can reasonably used as a primi-
tive "playback" client for X sessions.
xtrapchar parses ANSI character sequences including applica-
tion program sequences to synthesize input events to X Win-
dow servers using the XTrap server extension. The intent of
this program is to serve as a sample implementation for
interfacing character-based alternative input sources into X
servers (e.g. voice recognition systems). Another applica-
tion might be "remote keyboards". The -v flag causes the
program to display XTrap configuration information and
echo's characters processed to stdout. If present, this
must be the first argument.
Note: xtrapchar has only been used with Digital Workstations
using the LK201 compatible keyboard. Though reasonable
effort was done to maintain portability, no claims are made
as to the current level of portability to non-DEC servers
for this program.
The xtrapproto command is a regression test designed to test
the basic XTrap protocol between a client and server. If a
given implementation is suspect, the results of this test
should be sent to an XTrap implementor and/or developer.
OPTIONS
-d[isplay] display
Specifies the server to record from or playback to; see
-e Record only (and all) events. Should be used when
creating input for
-f script
The pathname of the script to be recorded / played back.
-v Verbose mode.
DIAGNOSTICS
X Toolkit Error: Can't load DEC-XTRAP extension
The XTrap X server extension has not been linked into the
specified X server.

IMPORTANT NOTE
Digital participated in the X Consortium's xtest working group which
chose to evolve XTrap functionality into a new extension for X11/R6
known as the RECORD extension (XTrap input synthesis functionality is
currently covered by the XTEST extension). It is strongly suggested
that users of XTrap technology begin developing against RECORD/XTEST
as it is the intention of the X Consortium to drive these two extensions
in the standards process for providing the protocol capturing/synthesis
functionality. Some members of the xtest working group are actively
researching migration issues between XTrap and RECORD. If you'd like
to contribute, please participate! Contact your local X Consortium Rep
for details on how to be added to the xtest mailing list.
