NAME

       termdebug - utilities for debugging interactive terminal programs.

DESCRIPTION

       termdebug  is  a  set  of  utilities to record and replay the input and output of terminal
       programs. Its main goal is to aid in developing and  debugging  terminal  programs.  Other
       programs  such  as  termrec/termplay, nethack-recorder/player and script/scriptreplay only
       record the output. However, when debugging an interactive terminal program, the  input  is
       often as important as the output.

       termdebug consists of the following utilities:

       tdrecord
              Starts a program and records its input and output.

       tdreplay
              Starts a program and replays the input of a recording.

       tdview Shows the output of a recording.

       tdrerecord
              Starts  a  program  and  replays  the input of a recording, recording the input and
              output to create a new recording.

       tdcompare
              Compares two recordings  to  determine  if  there  are  differences.  The  reported
              differences  can  be  either  on the exact input/output behaviour, or on the visual
              behaviour.

GRAMMAR

       The recordings made with the termdebug utilities  use  a  simple  format.  Each  recording
       consists of a set of directives with arguments. White space is not important. The language
       supports line comments which start at # and run to the end of the  line.  The  only  other
       elements  are  numbers  (a  sequence  of digits) and strings. Strings start and end with a
       double qoute, and use C-style escaping.  The following directives are known:

       env name value
              Set the value of environment variable name to value. name and  value  are  strings.
              All env directives must appear before the start directive.

       window_size columns lines [delay [> min_delay]]
              Set the terminal window size to columns by lines_. May be specified both before and
              after the start directive. On optional delay  in  milliseconds  may  be  specified.
              Furthermore,  min_delay  may  be  specified  to  force a wait of at least min_delay
              milliseconds regardless of program options changing the key delay.

       start client [argument+]
              The start directive indicates the client to start. Zero or more arguments  for  the
              client may be specified. client and argument are strings.

       require_version version
              Tell  the interpreter that the script langauge version must be version. The current
              version is 1.

       The following directives may only appear after the start directive:

       expect string+
              Indicate what output to expect. One or more strings may be specified.

       send (delay string [> min_delay)+
              Specify one or more key strings to send to the client program. delay is  the  delay
              in  miliseconds  to  wait  before  sending  string.  Furthermore,  min_delay may be
              specified to force a wait of at least min_delay milliseconds regardless of  program
              options changing the key delay.

       expect_exit status
              Signal that the client should stop at this point, returning status.

       expect_suspend
              Indicate that the client should suspend itself at this point.

       interact
              Indicate  the  interaction  with  the  user  should  be  started at this point. Any
              directives after this point will be ignored.
