 The heart of TiddlyWiki can be seen as an extensible representation transformation engine. 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.
 
-The most important transformations are from `text/x-tiddlywiki` wikitext into `text/html` or `text/plain` but the engine is used throughout the system for other transformations, such as converting images for display in HTML, sanitising fragments of JavaScript, and processing CSS.

 You can explore this mechanism by opening the JavaScript console in your browser. Typing this command will replace the text of the tiddler `HelloThere` with new content:

 WikiText is a concise, expressive way of typing a wide range of text formatting, hypertext and interactive features. It allows you to focus on writing without a complex user interface getting in the way. It is somewhat similar to [[MarkDown|http://daringfireball.net/projects/markdown/]], but with more of a focus on linking and the interactive features.

 </p></div><h1> Boot Mechanism</h1><div class=''><h1>Introduction</h1><p><a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='TiddlyWiki5'>TiddlyWiki5</a> is based on a 1,000 line boot kernel that runs on node.js or in the browser, with all other functionality added via dynamically loaded modules.</p><p>The kernel boots just enough of the <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='TiddlyWiki'>TiddlyWiki</a> environment to allow it to load tiddlers and execute <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='JavaScript'>JavaScript</a> modules. Plugin modules are written like <code>node.js</code> modules.</p><p>There are many <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='ModuleType'>different types of module</a>: parsers, serializers, deserializers, macros etc. It goes much further than you might expect. For example, individual tiddler fields are modules, too: there's a module that knows how to handle the <code>tags</code> field, and another that knows how to handle the special behaviour of the <code>modified</code> and <code>created</code> fields.</p><p>Some plugin modules have further sub-plugins: the wikitext parser, for instance, accepts rules as individual plugin modules.</p><h1>Plugins and Modules</h1><p>In <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='TiddlyWiki5'>TiddlyWiki5</a>, <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='Plugins'>Plugins</a> are bundles of tiddlers that are distributed and managed as one; <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='Modules'>Modules</a> are <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='JavaScript'>JavaScript</a> tiddlers with a module type identifying when and how they should be executed.</p><p>The tiddler <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='%24%3A%2Fcore%2Fboot.js'>$:/core/boot.js</a> is a barebones <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-resolves' href='TiddlyWiki'>TiddlyWiki</a> kernel that is just sufficient to load the core plugin modules and trigger a startup module to load up the rest of the application.</p><p>The kernel includes:</p><ul><li> Several short shared utility functions</li><li> A handful of methods implementing the plugin module mechanism</li><li> The <code>$tw.Tiddler</code> class (and field definition plugins)</li><li> The <code>$tw.Wiki</code> class (and tiddler deserialization methods)</li><li> Code for the browser to load tiddlers from the HTML DOM</li><li> Code for the server to load tiddlers from the file system</li></ul><p>Each module is an ordinary <code>node.js</code>-style module, using the <code>require()</code> function to access other modules and the <code>exports</code> global to return <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='JavaScript'>JavaScript</a> values. The boot kernel smooths over the differences between <code>node.js</code> and the browser, allowing the same plugin modules to execute in both environments.</p><p>In the browser, <code>core/boot.js</code> is packed into a template HTML file that contains the following elements in order:</p><ul><li> Ordinary and shadow tiddlers, packed as HTML <code>&lt;DIV&gt;</code> elements</li><li> <code>core/bootprefix.js</code>, containing a few lines to set up the plugin environment</li><li> <a class='tw-tiddlylink tw-tiddlylink-internal tw-tiddlylink-missing' href='JavaScript'>JavaScript</a> modules, packed as HTML <code>&lt;SCRIPT&gt;</code> blocks</li><li> <code>core/boot.js</code>, containing the boot kernel</li></ul><p>On the server, <code>core/boot.js</code> is executed directly. It uses the <code>node.js</code> local file API to load plugins directly from the file system in the <code>core/modules</code> directory. The code loading is performed synchronously for brevity (and because the system is in any case inherently blocked until plugins are loaded).</p><p>The boot kernel sets up the <code>$tw</code> global variable that is used to store all the state data of the system.
