Devel::Caller - meatier versions of caller

SYNOPSIS

Top

 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

Top

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

Top

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.
