+
+The main boot kernel for TiddlyWiki. This single file creates a barebones TW environment that is just
+sufficient to bootstrap the plugins containing the main logic of the applicaiton.
+
+On the server this file is executed directly to boot TiddlyWiki. In the browser, this file is packed
+into a single HTML file along with other elements:
+
+# bootprefix.js
+# <module definitions>
+# boot.js
+
+The module definitions on the browser look like this:
+
+	$tw.defineModule("MyModule","moduletype",function(module,exports,require) {
+	// Module code inserted here
+	return exports;
+	});
+
+In practice, each module is wrapped in a separate script block.

+title: $:/core/modules/macros/slider.js
+type: application/javascript
+module-type: macro
+
+!Introduction
+The slider macro is used to selectively reveal a chunk of text. By default, it renders as a button that may be clicked or touched to reveal the enclosed text.
+
+The enclosed text can be a string of WikiText or be taken from a target tiddler.
+
+The current state of the slider can be stored as the string "open" or "closed" in a specified tiddler. If the value of that tiddler changes then the slider is automatically updated. If no state tiddler is specified then the state of the slider isn't retained, but the slider still works as expected.
+!!Parameters
+|`state` //(defaults to 1st parameter)// |The title of the tiddler to contain the current state of the slider |
+|`default` |The initial state of the slider, either `open` or `closed` |
+|`class` |A CSS class to be applied to the slider root element |
+|`content` |The WikiText to be enclosed in the slider. Overrides the `target` parameter, if present |
+|`target` //(defaults to 2nd parameter)// |The title of the tiddler that contains the enclosed text. Ignored if the `content` parameter is specified |
+|`label` //(defaults to 3rd parameter)// |The plain text to be displayed as the label for the slider button |
+|`tooltip` //(defaults to 4th parameter)// |The plain text tooltip to be displayed when the mouse hovers over the slider button |
+!!Markup
+The markup generated by the slider macro is:
+{{{
+	<span class="tw-slider {user defined class}">
+		<a class="btn-info">{slider label}</a>
+		<div class="tw-slider-body" style="display:{state}">{slider content}</div>
+	</span>
+}}}
+!!Examples
+A minimal slider:
+{{{
+<<slider target:MyTiddler>>
+}}}
+!!Notes
+The slider is a good study example of a simple interactive macro.

+type: application/javascript
+module-type: macro
+
+The tiddler macros transcludes another macro into the tiddler being rendered.
+
+Parameters:
+	target: the title of the tiddler to transclude
+	template: the title of the tiddler to use as a template for the transcluded tiddler
+	with: optional parameters to be substituted into the rendered tiddler
+
+The simplest case is to just supply a target tiddler:
+
+<<tiddler Foo>> or <<transclude target:Foo>>
+
+This will render the tiddler Foo within the current tiddler. If the tiddler Foo includes
+the view macro (or other macros that reference the fields of the current tiddler), then the
+fields of the tiddler Foo will be accessed.
+
+If you want to transclude the tiddler as a template, so that the fields referenced by the view
+macro are those of the tiddler doing the transcluding, then you can instead specify the tiddler
+as a template:
+
+<<tiddler template:Foo>>
+
+The effect is the same as the previous example: the text of the tiddler Foo is rendered. The
+difference is that the view macro will access the fields of the tiddler doing the transcluding.
+
+The `target` and `template` parameters may be combined:
+
+<<tiddler target:Foo template:Bar>>
+
+Here, the text of the tiddler `Bar` will be transcluded, with the macros within it accessing the fields
+of the tiddler `Foo`.
+
+Finally, the `with` parameter is used to substitute values for the special markers $1, $2, $3 etc. The
+substitutions are performed on the tiddler whose text is being rendered: either the tiddler named in
+the `template` parameter or, if that parameter is missing, the tiddler named in the `target` parameter.

+
+Parses a block of tiddlywiki-format wiki text into a parse tree object. This is a transliterated version of the old TiddlyWiki code. The plan is to replace it with a new, mostly backwards compatible parser built in PEGJS.
+
+A wikitext parse tree is an array of objects with a `type` field that can be `text`,`macro` or the name of an HTML element.
+
+Text nodes are represented as `{type: "text", value: "A string of text"}`.
+
+Macro nodes look like this:
+`
+{type: "macro", name: "view", params: {
+	one: {type: "eval", value: "2+2"},
+	two: {type: "string", value: "twenty two"}
+}}
+`
+HTML nodes look like this:
+`
+{type: "div", attributes: {
+	src: "one"
+	styles: {
+		"background-color": "#fff",
+		"color": "#000"
+	}
+}}
+`

+* ''Element'' - represents a single HTML element
+* ''Text'' - represents an HTML text node
+* ''Entity'' - represents an HTML entity node
+* ''Raw'' - represents a chunk of unparsed HTML text

+
+* `eventListeners` is an array of {filter: <string>, listener: fn}
+* `changedTiddlers` is a hashmap describing changes to named tiddlers since wiki change events were
+last dispatched. Each entry is a hashmap containing two fields:
+	modified: true/false
+	deleted: true/false
+* `changeCount` is a hashmap by tiddler title containing a numerical index that starts at zero and is
+	incremented each time a tiddler is created changed or deleted
+* `caches` is a hashmap by tiddler title containing a further hashmap of named cache objects. Caches
+	are automatically cleared when a tiddler is modified or deleted
+* `macros` is a hashmap by macro name containing an object class inheriting from the Macro tree node
