 title: ParsingMechanism
 tags: docs mechanism
 
-TiddlyWiki parses the content of tiddlers to build an internal tree representation that is used for several purposes:
 
-* Rendering a tiddler to other formats (e.g. converting wikitext to HTML)
-* Detecting outgoing links from a tiddler, and from them...
-* ...computing incoming links to a tiddler
-* Detecting tiddlers that are orphans with no incoming links
-* Detecting tiddlers that are referred to but missing
-
-The parse tree is built when needed, and then cached by the WikiStore until the tiddler changes.
-
-TiddlyWiki5 uses multiple parsers:
-
-* Wikitext ({{{text/vnd.tiddlywiki}}}) in `js/WikiTextParser.js`
-* JavaScript ({{{text/javascript}}}) in `js/JavaScriptParser.js`
-* Images ({{{image/png}}} and {{{image/jpg}}}) in `js/ImageParser.js`
-* JSON ({{{application/json}}}) in `js/JSONParser.js`
-Additional parsers are planned:
-* CSS ({{{text/css}}})
-* Recipe ({{{text/vnd.tiddlywiki-recipe}}})
-
-One global instance of each parser is instantiated in `js/App.js` and registered with the main WikiStore object.
-
-The parsers are all used the same way:
-
-$$$.js
-var parseTree = parser.parse(type,text) // Parses the text and returns a parse tree object
-$$$
-
-The parse tree object exposes the following fields:
-
-$$$.js
-var renderer = parseTree.compile(type); // Compiles the parse tree into a renderer for the specified MIME type
-console.log(parseTree.toString(type)); // Returns a readable string representation of the parse tree (either `text/html` or `text/plain`)
-var dependencies = parseTree.dependencies; // Gets the dependencies of the parse tree (see below)
-$$$
-
-The dependencies are returned as an object like this:
-
-{{{
-{
-	tiddlers: {"tiddlertitle1": true, "tiddlertitle2": false},
-	dependentAll: false
-}
-}}}
-
-The `tiddlers` field is a hashmap of the title of each tiddler that is linked or included in the current one. The value is `true` if the tiddler is a //'fat'// dependency (ie the text is included in some way) or `false` if the tiddler is a //`skinny`// dependency.
-
-The `dependentAll` field is used to indicate that the tiddler contains a macro that scans the entire pool of tiddlers (for example the `<<list>>` macro), and is potentially dependent on any of them. The effect is that the tiddler should be rerendered whenever any other tiddler changes.
