The yawiki engine is the underlying rendering engine of the yawiki application. It is a standalone rendering engine to convert wiki markup into HTML. It can be included in any application. So far it covers three different markups: BBCode, the old yawiki markup, and the Creole 1.0 specification.
Rextile allows you to build XHTML documents and entire Web sites with ease. You write text using Textile (a format much more concise than XHTML), automate document parts with Ruby scripting, and generate the site offline (the server gets static XHTML). Rextile was inspired by Xilize. It uses RedCloth to convert Textile to XHTML, erb to run script blocks, and Hpricot for DOM manipulation.
rest2web is a tool for automatically maintaining Web sites or parts of Web sites. It integrates with docutils so that contents can be kept in reStructured Text or HTML. It has a powerful templating and macro system and can automatically generate index pages and navigation trails (like sidebars and breadcrumbs). It generates static HTML and can generate relative links, which means that sites can be viewed from the filesystem. A "uservalues" system assists with creating sites in multiple languages.
