title: TextReference
|
|
|
|
A TextReference identifies a chunk of text from a tiddler that can be retrieved or modified depending on the context.
|
|
|
|
Text references are made up of several parts, most of which can be optional:
|
|
|
|
* `<tiddler title>` - the text [[field|TiddlerFields]] of the specified tiddler
|
|
* `<tiddler title>!!<metadata field>` - a tiddler metadata [[field|TiddlerFields]] (eg, `modified`, `modifier`, `type` etc)
|
|
* `!!<metadata field>` - a metadata [[field|TiddlerFields]] of the current tiddler
|
|
* `<tiddler title>##<property index>` - extracts a named property from DataTiddlers
|
|
|
|
Text references can be used in several places:
|
|
|
|
* As IndirectOperands within TiddlerFilters (eg, `<$list filter="[tag{MyTag!!name}]"/>`)
|
|
* As IndirectAttributes of an element or widget (eg, `<$widget attrib={{Title!!description}}/>`)
|
|
* As the operand of a shortcut transclusion (eg, `{{MyTiddler!!title}}`)
|
|
* As the `state` attribute of the RevealWidget and the LinkCatcherWidget
|
|
|
|
//There are probably other places where a title is being used but it would be more flexible to support arbitrary text references//
