NAME¶
Dir::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".
