Manual Reference Pages - DIR::SELF (3)
Dir::Self - a __DIR__ constant for the directory your source file is in
use lib __DIR__ . "/lib";
my $conffile = __DIR__ . "/config";
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
its 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 dont 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.
