NAME ^

URI::Find::Simple - a simple interface to URI::Find

SYNOPSIS ^

  use URI::Find::Simple qw( list_uris );
  my @list = list_uris($text);

  my $html = change_uris($text, sub { "<a href=\"$_[0]\">$_[0]</a>" } );

DESCRIPTION ^

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.

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.

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.

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'.
