Devel::Caller - meatier versions of caller
caller
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'
caller_cv gives you the coderef of the subroutine being invoked at the call frame indicated by the value of $level
caller_cv
Returns the arguments passed into the caller at level $level
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
called_with
constants are returned as undef in both cases
undef
called_as_method returns true if the subroutine at $level was called as a method.
called_as_method
All of these routines are susceptible to the same limitations as caller as described in "caller" in perlfunc
The deparsing of the optree performed 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.
