Entering Commands at the TTY

Rather than entering commands at the debugger console, you may prefer to enter commands at the terminal window DDD was invoked from.

When DDD is invoked using the --tty option, it enables its TTY interface, taking additional debugger commands from standard input and forwarding debugger output to standard output, just as if the inferior debugger had been invoked directly. All remaining DDD functionality stays unchanged.

By default, the debugger console remains closed if DDD is invoked using the --tty option. Use View => Debugger Console to open it.

DDD can be configured to use the readline library for reading in commands from standard input. This GNU library provides consistent behavior for programs which provide a command line interface to the user. Advantages are GNU Emacs-style or Illegal HTML tag removed : vi-style inline editing of commands, csh-like history substitution, and a storage and recall of command history across debugging sessions. See Command Line Editing, for details on command-line editing via the TTY interface.
