 uf_uristr - Expand URI using heuristics


NAME

uf_uristr - Expand URI using heuristics


SUPPORTED PLATFORMS

  • Linux
  • Solaris
  • Windows

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 builtin heuristics. Strings that already represent absolute URIs (i.e. start with a scheme: part) are never modified and are returned unchanged. The main use of these functions are 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)
The uf_uristr() function will try to make the string passed as argument 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)
This functions work the same way as uf_uristr() but it will return a URI object.


ENVIRONMENT

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

COUNTRY
This is 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 the Locale::Country manpage.

URL_GUESS_PATTERN
Contain 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.
