Introduction

The ImportVariablesWidget imports macro and variable definitions from a list of other tiddlers and makes them available to its children. For example:

<$importvariables filter="[tag[mySpecialMacros]]">
All the macros defined in tiddlers with the tag "mySpecialMacros" are available here
</$importvariables>

Attributes and Content

The content of the importvariables widget is the scope within which the imported variable definitions are available.

Global Macros

So-called global macros are implemented within the main page template ($:/core/ui/PageTemplate) by wrapping the page content in the following importvariables widget:

<$importvariables filter="[[$:/core/ui/PageMacros]] [all[shadows+tiddlers]tag[$:/tags/Macro]!has[draft.of]]">
...
</$importvariables>

\import Pragma

Introduced in v5.1.18 The Pragma: \import is an alternative syntax for using the ImportVariablesWidget. For example, the previous example could be expressed as:

\import [[$:/core/ui/PageMacros]] [all[shadows+tiddlers]tag[$:/tags/Macro]!has[draft.of]]
