uri::find::delimited
URI::Find::Delimited(3pm) User Contributed Perl Documentation URI::Find::Delimited(3pm)
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 char-
acter will not be matched, ie your callback will not be executed for them and they'll be treated just as normal text.
This is kinda lame 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.

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.
