NAME

URI::ImpliedBase - magically force all URIs to be absolute

SYNOPSIS

  use URI::ImpliedBase;

  # Set the base to search.cpan.org
  $u = URI::ImpliedBase->new("http://search.cpan.org");

  $v = URI::ImpliedBase->new('subdir')
  print $v->as_string;  # prints http://search.cpan.org/subdir

  # No default now
  URI::ImpliedBase->clear();

  # Force current working directory to be the URI
  $w = URI::ImpliedBase->new("../wsdl/test.wsdl");
  print $w->as_string;  # prints (e.g.) file:///Users/joe/wsdl/test.wsdl

DESCRIPTION

This module is a drop-in replacement for URI. It wraps the new() method with some extra code which automatically captures either the base of the supplied URI (if it is absolute), or supplies the current base to "URI-"new_abs()> (if it is relative). If the current base is unset when a relative URI is supplied, the current working directory is used to build a ``file:'' URI and this is saved as the current base.

You can force a new base at any time by calling "URI::ImpliedBase-"clear()>.

USAGE

See the section for typical usage.

BUGS

Whether or not the current directory stuff works for a non-UNIX OS is currently unknown.

The base is stored internally at the moment; this may be problematic for multi-threaded code.

SUPPORT

Contact the author for support on an informal basis. No guarantee of response in a timely fashion.

CLASS METHODS

new

The new method uses "URI-"new()> to convert the incoming string into a URI object. It extracts the scheme and path if it can, and saves them as the new default base.

If there is no scheme, but there is a path, and there's no existing default base,"URI::ImpliedBase" guesses that the path is a reference to the local filesystem relative to the current working directory. It saves the current working directory as the base and "file:" as the scheme, then uses these to build an absolute "file:" URI and returns it.

If there's no scheme, and there is a path, and there is a default base, "URI::ImpliedBase" uses the default base to convert the path to an absolute URI.

The base is stored in a package lexical, $current_base. This may be a problem for multithreaded code, or code under "mod_perl" or "mod_soap"; this code has not been tested in these environments.
