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/" 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.

If you use or 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
