TWiki Filter is a set of custom content filters that formats nodes using TWiki style formatting. This module will help users converting from TWiki to Drupal, or provide an alternative formatting method for nodes.
TWiki Filter is in development and not yet ready for official release, however it is usable. Currently bulleted lists, numbered lists, tables (no sorting), headings, WikiWords, and basic formatting are supported.
December 2008 Update: I am currently rewriting the module to use the theme() function. Work is slow. Sorry.
TWiki WikiWord support has been added. Webs have been implemented by using taxonomy vocabulary 'Webs' with unique and mandatory terms for each web. You can then select a Web for each node. [[Web.Topic][Description]] does not replace Web.Topic with Description, but it does work for [[url][Description]].
taxonomy module is required for Web support. Setup a vocabulary called "Webs" with unique terms.
pathauto module recommended for the WikiWord filter if you set up Webs. Setup for node paths: [term-raw]/[title-raw].
