! 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|Filters]] 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]]">
|
|
...
|
|
</$importvariables>
|
|
```
|
|
|
|
! `\import` Pragma
|
|
|
|
<<.from-version "5.1.18">> The `\import` [[pragma|Pragma]] is an alternative syntax for using the ImportVariablesWidget. For example, the previous example could be expressed as:
|
|
|
|
```
|
|
\import [[$:/core/ui/PageMacros]] [all[shadows+tiddlers]tag[$:/tags/Macro]!has[draft.of]]
|
|
``` |
