I have the following problem: in a method of some Perl class I need to know the directory in which resides the class's module file.
I found a solution, shown in the module below.
Question to brethren: Is there a better and/or simpler way to obtain this information?

TIA
Rudif


#! perl -w
# file h:/devperl/perlmonks/Test/ModDir.pm

package Test::ModDir;
use strict;
use File::Basename;

sub new {
    my ($class, %args) = @_;
    my $self = {};
    bless $self, $class;
    return $self;
}

sub moduleDir {
    my $self = shift;
    my $class = ref $self;    # "ModuleDir::ModDir"
    (my $moduleFile = "$class.pm") =~ s!::!/!;
    my $modulePath = $INC{$moduleFile};
#    print "module $_ from file $INC{$_}\n" foreach keys %INC;
    my $moduleDir = dirname $modulePath;
}

1;
__END__



#! perl -w
# file h:/devperl/perlmonks/TestModuleDir.pm

use strict;
use lib qw ( h:/devperl/perlmonks );

use Test::ModDir;

my $md = Test::ModDir->new;

printf "===%s===\n", $md->moduleDir;

### prints ===h:/devperl/perlmonks/Test===

__END__
