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 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 program
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
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.
