[Michele Tomaiuolo] is 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 0.4, it experimentally supports:

* Automatic inlining of images when links end with .jpg etc.
* [Quotation] (e-mail style)
* [Address] (or [Signature]: http://www.w3.org/TR/html4/struct/global.html#h-7.5.6 - start a line with two dashes)
* [Superscript] (ordinals as 1st, 1ér etc are also automatically superscripted)

It also has 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 has been used to create a [Drupal filter|http://drupal.org/project/pearwiki_filter].

Note. Single newlines are handled as in most wikis (ignored), but if the {{{Newline}}} rule is removed (commenting a single line) from the {{{$rules}}} array in {{{Creole.php}}}, they will be handled as in word-processors (meaning a paragraph break). A custom {{{$rules}}} array can also be passed as a parameter to the {{{Text_Wiki_Creole}}} constructor.
