=head1 NAME
URI::Find::Simple - a simple interface to URI::Find
=head1 SYNOPSIS
use URI::Find::Simple qw( list_uris );
my @list = list_uris($text);
my $html = change_uris($text, sub { "<a href=\"$_[0]\">$_[0]</a>" } );
=head1 DESCRIPTION
L<URI::Find> is all very well, but sometimes you just want a list of the
links in a given piece of text, or you want to change all the urls in
some text somehow, and don't want to mess with callback interfaces.
This module uses URI::Find, but hides the callback interface, providing two
functions - one to list all the uris, and one to change all the uris.
=head2 list_uris( text )
returns a list of all the uris in the passed string, in the form output by
the URI->as_string function, not the form that they exist in the text.
=head2 change_uris( text, sub { code } )
the passed sub is called for every found uri in the text, and it's return
value is substituted into the string. Returns the changed string.
=head1 CAVEATS, BUGS, ETC
The change_uris function is only just nicer than the callback interface. In
some ways it's worse. I's prefer to just pass an s/// operator somehow, but
I don't think that's possible.
The list_uris function returns the stringified versions of the URI objects,
this seemed to be the sensible thing. To present a consistent interface, the
change_uris function operates on these strings as well, which are not the same
as the strings actually present in the original. Therefore this code:
my $text = change_uris($text, sub { shift } );
may not return the same thing you pass it. URIs such as <URI:http://jerakeen.org>
will be converted to the string 'http://jerakeen.org'.
