!! Introduction
|
|
|
|
This tiddler describes the different ways in which [[macros|Procedures]] can be defined.
|
|
|
|
!! Procedure Definition Pragma
|
|
|
|
Macros are created using the [[Pragma: \procedure]] at the start of a tiddler. The definitions are available in the rest of the tiddler that defines them, plus any tiddlers that it transcludes.
|
|
|
|
```
|
|
\define my-procedure(param)
|
|
This is the macro text (param=<<param>>)
|
|
\end
|
|
```
|
|
|
|
!! Procedure Definition with Set Widget
|
|
|
|
Procedures are implemented as a special kind of [[variable|Variables]] and so internally are actually defined with a <<.wlink SetWidget>> widget.
|
|
|
|
```
|
|
<$set name="my-procedure" value="This is the procedure text">
|
|
...
|
|
</$set>
|
|
```
|
|
|
|
<<.note """that it is not currently possible to specify parameters when defining a procedure with the <<.wlink SetWidget>> widget.""">>
|
|
|
|
!! Importing Procedure Definitions
|
|
|
|
The [[Pragma: \import]] or <<.wlink ImportVariablesWidget>> widget can be used to copy procedure definitions from another tiddler.
|
|
|
|
!! `$:/tags/Macro` Tag
|
|
|
|
Global procedures can be defined using the [[SystemTag: $:/tags/Macro]].
|
|
|
|
The tag [[SystemTag: $:/tags/Macro/View]] is used to define procedures that should only be available within the main view template and the preview panel.
|
|
|
|
The tag [[SystemTag: $:/tags/Macro/View/Body]] is used to define procedures that should only be available within the main view template body and the preview panel.
