! Introduction
|
|
|
|
The macro call widget provides an alternative syntax for invoking macros. The advantage of the widget form is that it allows macro parameters to be specified as widget attributes, thus allowing indirection and macro values to be set.
|
|
|
|
For example, a macro called `italicise` that takes a single parameter called `text` can be invoked in any of these ways:
|
|
|
|
```
|
|
<<italicise "Text to be made into italics">>
|
|
<<italicise text:"Text to be made into italics">>
|
|
<$macrocall $name="italicise" text="Text to be made into italics"/>
|
|
```
|
|
|
|
! Content and Attributes

|
|
|
The content of the `<$macrocall>` widget is ignored.
