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.

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. If you encounter problems, have questions, etc. with XTrap, please contact via mail, phone, etc. at: Ken Miller firstname.lastname@example.org (VOICE) 603-881-6221 (FAX) 603 881-2257 or paper mail at: Digital Equipment Corp.
