The heart of TiddlyWiki is an extensible representation transformation engine for text and images. Given the text of a tiddler and its associated ContentType, the engine can produce a rendering of the tiddler in a new ContentType. Furthermore, it can efficiently selectively update the rendering to track any changes in the tiddler or its dependents.

! Overview

The following diagram shows the internals of TiddlyWiki as a stack of tiddlers above a processing pipeline that converts WikiText into HTML.

The processing pipeline shows how WikiText is parsed by a stack of parse rules into a parse tree. The parse tree is rendered as a tree of widgets, which is synchronised into the DOM via the RefreshMechanism.
|
||
|
|
|
||
|
|
DOM events trigger actions on widgets which update the tiddler store. The updates trigger a change event which in turn triggers the refresh mechanism to update the DOM.
