to warm up for tomorrow's 3.2alpha1 release, I did a mini-sprint on pdb issues today. I'm pleased to report that 14 issues could be closed, and pdb got a range of small new features, such as commands on the command line, "until " or "longlist" showing all the code for the current function (the latter courtesy of Antonio Cuni's pdb++).

I haven't played with pdb++ (I might have to do something about that) but it's awesome that you're giving pdb some love.

One issue that's not yet closed is #7245, which adds a (very nice IMO) feature: when you press Ctrl-C while the program being debugged runs, you will not get a traceback but execution is suspended, and you can debug from the current point of execution -- just like in gdb.

That would be nice.

Another question is about a feature of pdb++ that I personally would like, but imagine would make others unhappy: one-letter abbreviations of commands such as c(ontinue) or l(ist) are also often-used variable names, so they are frequently typed without the required "!" or "print" that would distinguish them from the command, and the command is actually executed. The feature in question would default to printing the variable in cases where one exists -- handy enough or too inconsistent?

Not that important to me...

Also, are there any other features you would like to see? One feature of pdb++ that is general enough and has no dependencies would be watch expressions...

...but watch expressions - and the equivalent of gdb's 'display' command - would be very cool. interact would also be useful and probably pretty easy to add.
