Hi all,
I am running VMS perl 5.8.6. I am using persistent perl and am eval'ing a file.
The problem is, sometimes I want to eval the file to debug it. To make matters worse, I need to use ptkdb to do the debugging.
I've tried the obvious things like putting perl -d:ptkdb into the first line of the file, and putting "use Devel::ptkdb" into PERL5LIB and PERLDBOPT all to no avail.
Is this even possible?
Thanks in advance,
-Doug
Code snippet follows:
...{
local *FH;
open FH, $filename or die "open '$filename' $!";
local($/) = undef;
my $sub = <FH>;
close FH;
#wrap the code into a subroutine inside our unique package
my $eval = qq{package $package; sub handler { $sub; }};
{
# hide our variables within this block
my($filename,$mtime,$package,$sub);
eval $eval;
}
die $@ if $@;
#cache it unless we're cleaning out each time
$Cache{$package}{mtime} = $mtime unless $delete;
}
eval {$package->handler;};
die $@ if $@;
