Such as?
And, pls compare this nifty ptkdb with cperl-mode+gud+perldb,
to give an us idea first.
Thanks,

Had rexx this property or what, where you could load a module or just any
piece of code from text file onto memory and run it?
It would be cool. Can I do that in perl?!

Thanks guys (all of you). You got it. I corrected the solver, it was a
programming mistake. Thank you!

Subject: the star before filehandle
Message-Id: <Pine.LNX.4.61.0509070843120.16284@grn-amd64-00.grntech.net>
Hi Y'all
Can someone direct me to doc on this convention:
local (*her_in, *her_out, *her_err);
this is from the IPC::Open3 module example
I know that local scopes it, but I cannot find anything anywhere (perl
programming by oreilly, and perdoc perlop) that tells me what the stars
before the filehandles do. Thank you
Rocky

Subject: Why doesn't this work?
Message-Id: <mr-7F6B39.16345507092005@individual.net>
This works:
###
#!/usr/bin/perl
use strict;
use warnings;
my $string = "12.00 Simpsons 12.30 Fresh prince 14.00 Superbowl";
my @list = split / ?(?=\d\d\.\d\d)/, $string;
foreach (@list){
print "$_\n";
}
###
And outputs:
12.00 Simpsons
12.30 Fresh prince
14.00 Superbowl
This doesn't work:
###
#!/usr/bin/perl
use strict;
use warnings;
my $string = "author:Jane Smith institution:university of Cambridge year:1976";
my @list = split / ?(?=\w+:)/, $string;
foreach (@list){
print "$_\n";
}
###
It outputs:
a
u
t
h
o
r:Jane Smith
i
n
s
t
i
t
u
t
i
o
n:university of Cambridge
y
e
a
r:1976
What makes it so different? The range matching (\w+)? I thought only variable
length was forbidden in lookback, not in look forward, or am I misunderstanding
something completely?
