10.3 Integrating DDD
====================

You can run DDD as an inferior debugger in other debugger front-ends,
combining their special abilities with those of DDD.

   To have DDD run as an inferior debugger in other front-ends, the
general idea is to set up your debugger front-end such that `ddd --tty'
is invoked instead of the inferior debugger.  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.

   In case your debugger front-end uses the GDB `-fullname' option to
have GDB report source code positions, the `--tty' option is not
required.  DDD recognizes the `-fullname' option, finds that it has
been invoked from a debugger front-end and automatically enables the
TTY interface.

   If DDD is invoked with the `-fullname' option, the debugger console
and the source window are initially disabled, as their facilities are
supposed to be provided by the integrating front-end.  In case of need,
you can use the `View' menu to re-enable these windows.

10.3.1 Using DDD with Emacs
---------------------------

To integrate DDD with Emacs, use `M-x gdb' or `M-x dbx' in Emacs to
start a debugging session.  At the prompt, enter `ddd --tty' (followed
by `--dbx' or `--gdb', if required), and the name of the program to be
debugged.  Proceed as usual.

10.3.2 Using DDD with XEmacs
----------------------------

To integrate DDD with XEmacs, set the variable `gdb-command-name' to
`"ddd"', by inserting the following line in your `~/.emacs' file:

     (setq gdb-command-name "ddd")

   You can also evaluate this expression by pressing <ESC> <:> and
entering it directly (<ESC> <ESC> for XEmacs 19.13 and earlier).

   To start a DDD debugging session in XEmacs, use `M-x gdb' or `M-x
gdbsrc'.  Proceed as usual.

10.3.3 Using DDD with XXGDB
---------------------------

To integrate DDD with XXGDB, invoke `xxgdb' as

     xxgdb -db_name ddd -db_prompt '(gdb) '
