Dir::Self(3) User Contributed Perl Documentation Dir::Self(3)NAMEDir::Self - a __DIR__ constant for the directory your source file is in
SYNOPSIS
use Dir::Self;
use lib __DIR__ . "/lib";
my $conffile = __DIR__ . "/config";
DESCRIPTION
Perl has two pseudo-constants describing the current location in your
source code, "__FILE__" and "__LINE__". This module adds "__DIR__",
which expands to the directory your source file is in, as an absolute
pathname.
This is useful if your code wants to access files in the same
directory, like helper modules or configuration data. This is a bit
like FindBin except it's not limited to the main program, i.e. you can
also use it in modules. And it actually works.
As of version 0.10 each use of "__DIR__" recomputes the directory name;
this ensures that files in different directories that share the same
package name get correct results. If you don't want this, "use
Dir::Self qw(:static)" will create a true "__DIR__" constant in your
package that contains the directory name at the point of "use".
