ok. i'm trying to write a vim plugin that will allow me to visually step through and debug my code.

i discovered this DB.pm module and that seems pretty cool. (maybe it is what activestate uses for their windows gui perl debugger since it was written by a guy who works there?) it seems to be a debugger api type thing that is exactly what i would like to make my life easier. but its not working.

i can't get the debugger to load the file. i try to load the file with:
$self->loadfile( $file, $linenumber )
but that doesn't seem to work. if you actually look at the code for loadfile() in DB.pm, it should return the filename if it succeeds. its not succeeding.

i think i'm doing something fundamentally wrong. any ideas? here is my code: 
#!/usr/bin/perl -w


package PerlDebugger;

use DB;
@ISA = qw( DB );


sub new {
   my $type = shift;
   my $self = {};
   bless $self, $type;
}  

sub startDebugger   {
   my $self = shift;
   my $sourceCode = shift;

   print "\n>>$sourceCode<<\n";

   $self->register();
   print ">>" . $self->loadfile( $sourceCode, -1 ) . "<<\n";
   print ">>" . $self->ready() . "<<\n";

   print "\n>>";
   print $DB::filename;
   print "<<\n";
}

sub quit   {
   my $self = shift;
   $self->done();
}

package main;
use strict;

my $code = "/home/eric/code/tmp/foo.pl";

my $dbgr = PerlDebugger->new();
$dbgr->startDebugger( $code );

my other option is to not use DB.pm at all and to use open2() on perl -d. which is not as pretty. and the annoying thing with that is the debugger writes to /dev/tty instead using STDOUT and STDIN, and that was giving me fits too because i want vim to display to /dev/tty and the debugger always takes over.
