Introduction
You can incorporate the content of one tiddler within another using the Transclusion notation:
{{MyTiddler}}transcludes a single tiddler{{MyTiddler||TemplateTitle}}displays the tiddler through a specified TemplateTiddler{{||TemplateTitle}}displays the specified template tiddler without altering the current tiddler{{MyTiddler|Parameter}}transcludes a single tiddler with a single parameter{{MyTiddler||TemplateTitle|Parameter|SecondParameter}}transcludes a single tiddler through a specified TemplateTiddler with two parameters
Transcluding Text References
You can also use a TextReference instead of a tiddler title:
{{MyTiddler!!field}}transcludes a specified field of a tiddler{{!!field}}transcludes a specified field of the current tiddler{{MyTiddler##index}}transcludes a specified indexed property of a DataTiddler{{##index}}transcludes a specified indexed property of the current DataTiddler
Filtered Transclusion
A similar syntax can be used to generate or transclude a list of tiddlers matching a specified filter:
{{{ [tag[mechanism]] }}}
{{{ [tag[mechanism]]||TemplateTitle }}}In contrast to Filtered Attribute Values, all items matching the filter are transcluded and not only the first.
Generated Widgets
The WikiText transclusion syntax generates a TiddlerWidget wrapped around a TranscludeWidget. For example, {{MyTiddler||TemplateTitle}} generates the following pair of widgets:
<$tiddler tiddler="MyTiddler">
<$transclude $tiddler="TemplateTitle"/>
</$tiddler>The filtered transclusion syntax {{{ [tag[mechanism]] }}} generates the following widgets
<$list filter="[tag[mechanism]]">
<$link />
</$list>or, when used with a template, {{{ [tag[mechanism]]||TemplateTitle }}} expands to
<$list filter="[tag[mechanism]]">
<$transclude tiddler="TemplateTitle" />
</$list>Multi-Valued Variable Display
New in v5.4.0 The ((var)) syntax can be used inline to display the values of a multi-valued variable, joined with a comma and space by default:
((myvar))
((myvar||:))The optional || delimiter specifies a custom separator string.
Inline Filter Display
New in v5.4.0 The (((filter))) syntax displays the results of a filter expression inline, joined with a comma and space by default:
((( [all[tiddlers]sort[]] )))
((( [all[tiddlers]sort[]] ||: )))The optional || delimiter specifies a custom separator string. This is the inline display counterpart to the filtered transclusion {{{ }}} syntax.
