NAME

       URI::Find::Delimited - Find URIs which may be wrapped in enclosing delimiters.

DESCRIPTION

       Works like URI::Find, but is prepared for URIs in your text to be wrapped in a pair of
       delimiters and optionally have a title. This will be useful for processing text that
       already has some minimal markup in it, like bulletin board posts or wiki text.

SYNOPSIS

         my $finder = URI::Find::Delimited->new;
         my $text = "This is a [http://the.earth.li/ titled link].";
         $finder->find(\$text);
         print $text;

METHODS

       new
             my $finder = URI::Find::Delimited->new(
                 callback      => \&callback,
                 delimiter_re  => [ '\[', '\]' ],
                 ignore_quoted => 1               # defaults to 0
             );

           All arguments are optional; defaults are provided (see below).

           Creates a new URI::Find::Delimited object. This object works similarly to a URI::Find
           object, but as well as just looking for URIs it is also aware of the concept of a
           wrapped, titled URI.  These look something like

             [http://foo.com/ the foo website]

           where:

           ·   "[" is the opening delimiter

           ·   "]" is the closing delimiter

           ·   "http://foo.com/" is the URI

           ·   "the foo website" is the title

           ·   the URI and title are separated by spaces and/or tabs

           The URI::Find::Delimited object will extract each of these parts separately and pass
           them to your callback.

           callback
               "callback" is a function which is called on each URI found. It is passed five
               arguments: the opening delimiter (if found), the closing delimiter (if found), the
               URI, the title (if found), and any whitespace found between the URI and title.

               The return value of the callback will replace the original URI in the text.

               If you do not supply your own callback, the object will create a default one which
               will put your URIs in 'a href' tags using the URI for the target and the title for
               the link text. If no title is provided for a URI then the URI itself will be used
               as the title. If the delimiters aren't balanced (eg if the opening one is present
               but no closing one is found) then the URI is treated as not being wrapped.

               Note: the default callback will not remove the delimiters from the text. It should
               be simple enough to write your own callback to remove them, based on the one in
               the source, if that's what you want.  In fact there's an example in this
               distribution, in "t/delimited.t".

           delimiter_re
               The "delimiter_re" parameter is optional. If you do supply it then it should be a
               ref to an array containing two regexes.  It defaults to using single square
               brackets as the delimiters.

               Don't use capturing groupings "( )" in your delimiters or things will break. Use
               non-capturing "(?: )" instead.

           ignore_quoted
               If the "ignore_quoted" parameter is supplied and set to a true value, then any
               URIs immediately preceded with a double-quote character will not be matched, ie
               your callback will not be executed for them and they'll be treated just as normal
               text.

               This is a bit of a hack but it's in here because I need to be able to ignore
               things like

                 <img src="http://foo.com/bar.gif">

               A better implementation may happen at some point.

CREDITS

       Tim Bagot helped me stop faffing over the name, by pointing out that RFC 2396 Appendix E
       uses "delimited". Dave Hinton helped me fix the regex to make it work for delimited URIs
       with no title. Nick Cleaton helped me make "ignore_quoted" work. Some of the code was
       taken from URI::Find.
