URI::Heuristic(3)                    User Contributed Perl Documentation                   URI::Heuristic(3)



NAME
       URI::Heuristic - Expand URI using heuristics

SYNOPSIS
        use URI::Heuristic qw(uf_uristr);
        $u = uf_uristr("perl");             # http://www.perl.com
        $u = uf_uristr("www.sol.no/sol");   # http://www.sol.no/sol
        $u = uf_uristr("aas");              # http://www.aas.no
        $u = uf_uristr("ftp.funet.fi");     # ftp://ftp.funet.fi
        $u = uf_uristr("/etc/passwd");      # file:/etc/passwd

DESCRIPTION
       This module provides functions that expand strings into real absolute URIs using some built-in
       heuristics.  Strings that already represent absolute URIs (i.e. that start with a "scheme:" part) are
       never modified and are returned unchanged.  The main use of these functions is to allow abbreviated
       URIs similar to what many web browsers allow for URIs typed in by the user.

       The following functions are provided:

       uf_uristr($str)
           Tries to make the argument string into a proper absolute URI string.  The "uf_" prefix stands for
           "User Friendly".  Under MacOS, it assumes that any string with a common URL scheme (http, ftp,
           etc.) is a URL rather than a local path.  So don't name your volumes after common URL schemes and
           expect uf_uristr() to construct valid file: URL's on those volumes for you, because it won't.

       uf_uri($str)
           Works the same way as uf_uristr() but returns a "URI" object.

ENVIRONMENT
       If the hostname portion of a URI does not contain any dots, then certain qualified guesses are made.
       These guesses are governed by the following two environment variables:

       COUNTRY   The two-letter country code (ISO 3166) for your location.  If the domain name of your host
                 ends with two letters, then it is taken to be the default country. See also
                 Locale::Country.

       URL_GUESS_PATTERN
                 Contains a space-separated list of URL patterns to try.  The string "ACME" is for some
                 reason used as a placeholder for the host name in the URL provided.  Example:

                  URL_GUESS_PATTERN="www.ACME.no www.ACME.se www.ACME.com"
                  export URL_GUESS_PATTERN

                 Specifying URL_GUESS_PATTERN disables any guessing rules based on country.  An empty
                 URL_GUESS_PATTERN disables any guessing that involves host name lookups.
