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 his-
torical. The display argument is parsed by the X Toolkit and speci-
fies 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 exten-
sion 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 sup-
port 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 exten-
sion. As stated earlier, it's input can be provided by xtrapout using
the -e qualifier. While it's primary function is for testing XTrap
and serving as an example for XTrap functionality, it can reasonably
used as a primitive "playback" client for X sessions.
xtrapchar parses ANSI character sequences including application pro-
gram sequences to synthesize input events to X Window 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 application 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 main-
tain 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 imple-
mentor 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 exten-
sions in the standards process for providing the protocol captur-
ing/synthesis functionality. Some members of the xtest working group
are actively researching migration issues between XTrap and RECORD.
