How do I use a Perl module from a relative location?

Question

I have a dir called foo, and in that I have lib and bin. The scripts in bin need stuff in lib. I do someth

Answer 1

I generally use this technique. Its sadly inspired from my PHP days:

Its handy in situations where you know where a given file will be relative to the current one, and aren't sure of the entry points it may be called in or the surrounding environment at calltime.

However, I would generally use this technique only for test scripts which need dummy libraries for emulating things.

use File::Basename ();
use Cwd            ();
my $base_dir;
my $relative_path; 
BEGIN {
    $realitive_path = '../../' # Path to base of project relative to the current file
    $base_dir = Cwd::realpath( File::Basename::dirname(__FILE__) .'/' . $relative_path );
}


use lib "${base_dir}/lib";
use Foo;

Ideally there should be some module somewhere that does this, if not, I'm half tempted to write one:

use Some::Module ();
use lib Some::Module::relative_self('../../lib', __FILE__ );
