For Debug::Fork::Tmux there's a DB::get_fork_TTY() to define and $DB::fork_TTY to assign to. (a tty name for the next debugger's process).

You're welcome, Peter, it's a quiet list, but there are some debugger relevant people on it ;-) -- Ciao Richard Foley http://www.rfi.net/books.html On Mon, Dec 03, 2012 at 03:11:34PM +0400, Peter Vereshagin wrote: > Hello. > > 2012/12/03 10:34:27 +0100 Richard Foley => To > debugger@perl.org : > RF> Here is an interesting module from Peter Vereshagin which might help with > RF> debugging forks under the perl debugger, if you use tmux version 1.6+ > RF> > RF> http://search.cpan.org/dist/Debug-Fork-Tmux > > Thank you very much Richard for your announce! > > The latest development (v1.10 currently) is at: > > http://gitweb.vereshagin.org/Debug-Fork-Tmux/README.html > > The latest Changes are: > > Searching for tmux binary (in PATH) and perl-5.8.9 minimum (in POD) > > Keeping at sight the things to improve (have them recorded). > > There is a GitHub page, too: > > https://github.com/petr999/Debug-Fork-Tmux > > v1.10 isn't yet on CPAN cause I always think twice before.

Re: Tmux helps to debug perl fork()s
Something I think about when I read about things like this whether there some sort of unifying principle that could be used in other debuggers or for other similar sorts of programs. Is there some support that a debugger should be providing to make things like this easier? Too often, especially with the venerable Perl debugger, you read about patch someone has that made that does some interesting thing. Or s a trick you can do in order to get something done that is commonly needed. It feels less like the "art" but rather knowing about a number of isolated tricks, or worse, workarounds that is relevant for one debugger on one programming language. That said, of course, all of this is cool.

Tmux helps to debug perl fork()s
Here is an interesting module from Peter Vereshagin which might help with debugging forks under the perl debugger, if you use tmux version 1.6+ http://search.cpan.org/dist/Debug-Fork-Tmux -- Ciao Richard Foley http://www.rfi.net/books.html
