NAME
Devel::Caller::Perl - Perl only implementation.
SYNOPSIS
use Devel::Caller::Perl qw[called_args];
sub permute_args {
my @args = @_;
my @caller_args = called_args( 0 );
my %caller_args =
map { $_ => $caller_args[$_] } 0 .. $#caller_args;
return \%caller_args;
}
sub dodad {
my $args = permute_args;
print $args->{0};
# ...
}ABSTRACT
This module allows a method to get at arguments passed to subroutines higher up in the call stack.
DESCRIPTION
FUNCTIONS
called_args [LEVEL]
called_args returns the arguments to the subroutine at LEVEL in the call stack. If no level is specified, 0 (zero) is assumed, that being our caller. If a list is expected, it will be returned. When a scalar is expected, a list reference will be returned.
If you want the number of arguments passed to the subroutine at LEVEL, there's nothing stopping you from getting it from caller.
my $number = (caller $level)[4];AUTHOR
