only::latest - Always use the latest version of a module in @INC
This document describes version 0.01 of only::latest, released November 4, 2003.
use lib "/some/dir"; use only::latest; use DBI; # use "/some/dir/DBI.pm" only if it's newer than system's
This module is for people with separately-maintained INC directories containing overlapping modules, who wishes to always use the latest version of a module, regardless of the directory it is in.
require a module living in more than one directory, the one with the highest
$VERSION is preferred, and its directory will be tried first during the next time. If there is a tie, the first-tried one is used.
The implementation puts a hook in front of
@INC; this means it should come after all
use lib statements.
If you wish to limit this module to some specific targets, list them as the import arguments, like this:
use only::latest qw(CGI CGI::Fast); use DBI; # not affected
