It is implemented in two main parts:

• Core Render Routines
• Plugin Hooks

Core Render Routines.

The function of the core render routines is to implement the TextFormattingRules. At certain points in processing the topic, the core makes calls to PluginsDotPm. PluginsDotPm in turn calls the plugins so that they can do any rendering they need to.

BeijingRelease

In BeijingRelease these are held in TWikiDotPm. (Together with Cgi Authentication, Date Manipulation and a miscellany of other functions. See TWikiPmProposedFurtherModularisation)

This is done by multiply parsing the topic text, tokenising it into chunks and converting anything that it recognises as it goes along.

CairoRelease, DakarRelease

Plugin Hooks

• See TWikiPlugins for documentation on how to write a plugin.
• See PluginsDotPm for links to the implementation and comments thereof
• See MorePluginHooks, MoreTechnicalPluginsDoc, PluginsReorgNote? for documentation on what plugins hooks are available.
