BFD(3p)

NAME
  BFD - Impromptu dumping of data structures for debugging purposes

SYNOPSIS
   my $scary_structure1 = foo();
   my $scary_structure2 = bar();
   use BFD; d $scary_structure1, " hmmm ", $scary_structure2, ...;
   ....

DESCRIPTION
Allows for impromptu dumping of output to STDERR. Useful when you want to take a peek at a nest Perl data structure by emitting (relatively) nicely formatted output with filename and line number prefixed to each line.

Basically,

    use BFD;d $foo;

is shorthand for

    use Data::Dumper;
    local $Data::Dumper::Indent    = 1;
    local $Data::Dumper::Quotekeys = 0;
    local $Data::Dumper::Terse     = 1;
    local $Data::Dumper::Sortkeys  = 1;
    my $msg = Dumper( $foo );
    $msg =~ s/^/$where: /mg;
    warn $msg;

I use this incantation soooo often that a TLA version is warranted. YMMV.

LIMITATIONS
Uses Data::Dumper, which has varying degrees of stability and usefulness on different versions of perl.
