URI::Heuristic - Expand URI using heuristics
use URI::Heuristic qw(uf_uristr);
$u = uf_uristr("perl"); # http://www.perl.com

$u = uf_uristr("aas"); # http://www.aas.no

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 modi-
fied 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:
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 vol-
umes after common URL schemes and expect uf_uristr() to construct
valid file: URL's on those volumes for you, because it won't.
Works the same way as uf_uristr() but returns a "URI" object.
If the hostname portion of a URI does not contain any dots, then cer-
tain 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.
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"
Specifying URL_GUESS_PATTERN disables any guessing rules
based on country. An empty URL_GUESS_PATTERN disables any
guessing that involves host name lookups.
