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.
| Attribute | Description |
|---|---|
| filter | Tiddler filter defining the tiddlers from which macro definitions will be imported |
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]]
