I'm working on a [Creole extension|http://pear.php.net/pepr/pepr-proposal-show.php?id=446] for the [PEAR Text_Wiki package|http://pear.php.net/package/Text_Wiki/]. You can already [see it in action|http://www.ce.unipr.it/~tomaiuol/creole_example.php].

Apart from all the elements defined in Creole 0.2, it experimentally supports:

* Automatic inlining of images when links end with .jpg etc.
* [Tables]
* [Quotations] (e-mail style)
* [Addresses] (or signatures: http://www.w3.org/TR/html4/struct/global.html#h-7.5.6 - start a line with two dashes)

When completed, it will also have a full renderer, to convert documents from other wiki syntaxes to Creole.

[Text_Wiki|http://pear.php.net/package/Text_Wiki/] is used by [Yawiki|http://wiki.ciaweb.net/yawiki/index.php?wiki=Yawiki], but it can be easily integrated into other php software. For example, it can be used to create a [Drupal filter|http://drupal.org/node/46944].

Your ideas and comments are welcome.
