! Introduction
|
|
|
|
The macro call widget provides a more flexible alternative syntax for invoking macros compared to the usual `<<macroname>>` syntax documented in [[Macros in WikiText]].
|
|
|
|
For example, a macro called `italicise` that takes a single parameter called `text` would usually be invoked like this:
|
|
|
|
```
|
|
<<italicise "Text to be made into italics">>
|
|
<<italicise text:"Text to be made into italics">>
|
|
```
|
|
|
|
The same macro can be invoked using the macro call widget like this:
|
|
|
|
```
|
|
<$macrocall $name="italicise" text="Text to be made into italics"/>
|
|
<$macrocall $name="italicise" text={{Title of tiddler containing text to be italicised}}/>
|
|
<$macrocall $name="italicise" text=<<textMaker "Another macro to generate the text to be italicised">>/>
|
|
```
|
|
|
|
The advantages of the widget formulation are:
|
|
|
|
* Macro parameters are specified as widget attributes, thus allowing indirection via `{{title!!field}}`, `<<macroname>>` or `{{{filter}}}`
|
|
* The output format can be chosen from several options:
|
|
** `text/html` wikifies the result of the macro
|
|
** `text/plain` wikifies the result of the macro and then extracts the plain text characters (ie. ignoring HTML tags)
|
|
** <<.from-version "5.1.23">> `text/raw` returns the result of the macro, without wikification
|
|
|
|
You can see several examples of the macro call widget within the core:
|
|
|
|
* Listing module information: [[$:/snippets/modules]]
|
|
* Listing field information: [[$:/snippets/allfields]]
|
|
* Generating `data:` URIs: [[$:/themes/tiddlywiki/starlight/styles.tid]]
