devel::stacktrace::withlexicals

Devel::StackTrace::WithLexicals(3pm)			User Contributed Perl Documentation		      Devel::StackTrace::WithLexicals(3pm)

NAME

       Devel::StackTrace::WithLexicals - Devel::StackTrace + PadWalker

SYNOPSIS

	   use Devel::StackTrace::WithLexicals;

	   my $trace = Devel::StackTrace::WithLexicals->new;
	   ${ $trace->frame(1)->lexical('$self') }->oh_god_why();

DESCRIPTION

       Devel::StackTrace is pretty good at generating stack traces.

       PadWalker is pretty good at the inspection and modification of your callers' lexical variables.

       Devel::StackTrace::WithLexicals is pretty good at generating stack traces with all your callers' lexical variables.

METHODS

       All the same as Devel::StackTrace, except that frames (in class Devel::StackTrace::WithLexicals::Frame) also have a "lexicals" method. This
       returns the same hashref as returned by PadWalker.

       If the "no_refs" option to Devel::StackTrace is used, then each reference is stringified. This can be useful to avoid leaking memory.

       Simple, really.

BUGS

       I had to copy and paste some code from Devel::StackTrace to achieve this (it's hard to subclass). There may be bugs lingering here.
