Oooh, what other stuff? As somebody who doesn't have a .perldb at all
(I'm not even sure I was aware of it before this thread) I'm intrigued
as to what's possible.
Well it's messy and apart from the "stop at test #n" hack it's nearly
all
either Mac/TextMate specific or Perl 5.10 specific - but here it is.
use TextMate::JumpTo qw(jumpto);

@DB::testbreak = grep { !$seen{$_}++ }
sort { $a <=> $b } ( split( /\s*,\s*/, $1 ),
@DB::testbreak );
require Test::Builder;
}
else {
$cmd_b->( @_ );
}
};
sub afterinit {
$trace |= 4; # Enable watchfunction
# Needed to work out where filenames are relative to
chomp( $base_dir = `pwd` );
$option{animate} = 0;
push @options, 'animate';
}
sub watchfunction {
if ( @DB::testbreak ) {
my $current = Test::Builder->new->current_test;
if ( $current + 1 >= $DB::testbreak[0] ) {
shift @DB::testbreak
while @DB::testbreak && $current + 1 >=
$DB::testbreak[0];

last unless defined $package;

# Doesn't really work

I use the debugger only infrequently, but perhaps with some tweaked
config I'd be inclined to use it more.
Having command history (5.10 only) was a key factor in getting me to use
it more. The gubbins that syncs debugger position with my editor is,
frankly, a mixed blessing. Generally it's a good thing but I probably
need to add an option to turn it off in the case that I'm debugging
something that I don't want to have open in my editor.
The editor sync is also the reason I wanted the break-at-test-#n hack to
exit any Test::* packages before stopping. Without that I end up with
half of Test::Builder / Test::More / Test::Whatever open in my editor :)
Any chance of a 'Me and My .perldb' (lightning) talk somewhere?
Well there's not that much to mine yet. But I am planning to do a talk
(Leeds.pm) on the Perl tools I use which would include those debugger
hacks. If it goes well with the home crowd I could probably do the same
talk for London.pm sometime :)
