ddd and python

[R. Bernstein]

Just tried it on GNU/Linux with software listed below and it worked. 

There's been a bit of work on improving pydb, getting it more in line
with the current python debugger pdb, and making it more like gdb.

See http://bashdb.sourceforge.net/pydb for information. This should
replace the pydb found in ddd which hasn't been maintained for about 6
years.

And in conjunction with the pydb improvements, there has been work in
updating ddd to handle the new features.

The changes are in the "pydb" branch of the ddd source tree, and a
"test" release of ddd incorporates this which you can get at:

  http://sourceforge.net/project/showfiles.php?group_id=61395

But having said this, I should mention a couple of known problems. The
last release of pydb (and current releases of pdb in Python and
probably the pydb of ddd), have all had problems tracking the source.
One problem, and I'm not sure I forget the details of the
characterization, is when the Python program is run outside of the
directory it resides in. And this situation also effects tracing
through imports, especially "import x.y as z". The current pydb
sources in CVS address this somewhat, and in the next release there
will be a gdb "directories" command which will allow you to set a
source lookup path.

Another problem but only with the released ddd-3.12-test5 and pydb
1.16 is the "cont"(inue) button is shown greyed out. The problem here
is that I've removed "cont" as 3nd alternative for "continue": both
"c" and "continue" work, and you can issue "c" or "continue" in the
debugger command line area. I've just committed the fix to ddd for
this. (Again, only in the pydb branch).
