NAME

Devel::Caller - meatier versions of "caller"

SYNOPSIS

  use Devel::Caller qw(caller_cv);
  $foo = sub { print "huzzah\n" if $foo == caller_cv(0) };
  $foo->();  # prints huzzah
 
  use Devel::Caller qw(called_with);
  sub foo { print called_with(0,1); }
  foo( my @foo ); # should print '@foo'
 
 

DESCRIPTION

caller_cv($level)
"caller_cv" gives you the coderef of the subroutine being invoked at the call frame indicated by the value of $level
caller_args($level)
Returns the arguments passed into the caller at level $level
caller_vars( $level, $names ) =item called_with($level, $names)
"called_with" returns a list of references to the original arguments to the subroutine at $level. if $names is true, the names of the variables will be returned instead

constants are returned as "undef" in both cases

called_as_method($level)
"called_as_method" returns true if the subroutine at $level was called as a method.

BUGS

All of these routines are susceptible to the same limitations as "caller" as described in ``caller'' in perlfunc

The deparsing of the optree perfomed by called_with is fairly simple-minded and so a bit flaky.

*
As a version 2.0 of Devel::Caller we no longer maintain compatibility with versions of perl earlier than 5.8.2. Older versions continue to be available from CPAN and backpan.
