Hi,

Irssi is an IRC client using Perl for scripting. I'm trying to attach a
debugger to its embedded Perl.

I'm using PERLDB_OPTS="RemotePort=127.0.0.1:5000" to let it connect to a
socket. Running and debugging a perl script started in the "normal" way works
fine: "perl -d -e 0" connects to the socket and I can control the debugger
from
there.

Now I changed irssi so that the arguments it passes to perl_parse and
PERL_SYS_INIT3 include "-d". Then when starting irssi, it connects to the
socket, and prints its usual "Loading DB routines"... "Enter h"... But when I
give any command (including "h") it doesn't respond. The irssi (and its Perl
scripts) continue to run fine.

Someone an idea of what could be going wrong?

Thanks.

Wouter.

/window new hide
/exec -interactive perl -d -e 0

But that doesn't echo your own commands into the window, so maybe something
like /exec -interactive tee /dev/stderr | perl -d -e 0, but that doesn't seem
to want to quit here without a kill.

Anyways, being able to actually debug irssi scripts would be nice...
Is this an irssi-specific problem? Is debugging Perl embedded into another
program in a way similar as in irssi rather unexplored territory, or is it
really supposed to work?
Perhaps it's because irssi (glib) controls the main loop and not Perl?

Wouter.
