The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.


URI::SmartURI - Subclassable and hostless URIs


Version 0.032


    my $uri = URI::SmartURI->new(
        { reference => 'http://host/bar/' }

    my $hostless = $uri->hostless; # '/foo/'

    $hostless->absolute; # 'http://host/foo/'

    $uri->relative; # '../foo/'


This is a sort of "subclass" of URI using delegation with some extra methods, all the methods that work for URIs will work on these objects as well.

It's similar in spirit to URI::WithBase.

It's also completely safe to subclass for your own use.


URI::SmartURI->new($str, [$scheme|{reference => $ref, scheme => $scheme}])

Takes a uri $str and an optional scheme or hashref with a reference uri (for computing relative/absolute URIs) and an optional scheme.

    my $uri = URI::SmartURI->new('');

    my $uri = URI::SmartURI->new('/', 'http');

    my $uri = URI::SmartURI->new(
        { reference => '' }

The object returned will be blessed into a scheme-specific subclass, based on the class of the underlying $uri->obj (URI object.) For example, URI::SmartURI::http, which derives from URI::SmartURI (or $uri->factory_class if you're subclassing.)

URI::SmartURI->new_abs($str, $base_uri)

Proxy for URI->new_abs

URI::SmartURI->newlocal($filename, [$os])

Proxy for URI::URL->newlocal



Returns the URI with the scheme and host parts stripped.


Accessor for the reference URI (for relative/absolute below.)


Returns the URI relative to the reference URI.


Returns the absolute URI using the reference URI as base.


stringification works, just like with URIs


and == does as well


Explicit equality check to another URI, can be used as URI::SmartURI::eq($uri1, $uri2) as well.


Accessor for the URI object methods are delegated to.


The class whose constructor was called to create the $uri object, usually URI::SmartURI or your own subclass. This is used to call class (rather than object) methods.


These are used internally by SmartURI, and are not interesting for general use, but may be useful for writing subclasses.


Returns a hashref of options for the $uri (reference and scheme.)


Converts, eg., "URI::http" to "URI::SmartURI::http".


Creates a new proxy class class for a URI class, with all exports and constructor intact, and returns its name, which is made using _resolve_uri_class (above).

$class->_inflate_uris(\@rray, $opts)

Inflate any URI objects in @rray into URI::SmartURI objects, all other members pass through unharmed. $opts is a hashref of options to include in the objects created.


Deflate any URI::SmartURI objects in @rray into the URI objects they are proxies for, all other members pass through unharmed.


On import with the -import_uri_mods flag it loads all the URI .pms into your class namespace.

This works:

    use URI::SmartURI '-import_uri_mods';
    use URI::SmartURI::WithBase;
    use URI::SmartURI::URL;

    my $url = URI::SmartURI::URL->new(...); # URI::URL proxy

Even this works:

    use URI::SmartURI '-import_uri_mods';
    use URI::SmartURI::Escape qw(%escapes);

It even works with a subclass of URI::SmartURI.

I only wrote this functionality so that I could run the URI test suite without much modification, it has no real practical value.


Please report any bugs or feature requests to bug-uri-smarturi at, or through the web interface at I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.


You can find documentation for this module with the perldoc command.

Thanks to folks on freenode #perl for helping me out when I was getting stuck, Somni, revdiablo, PerlJam and others whose nicks I forget.
