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 perlfuncThe 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.
