Macro with conditional output

[Laurent Bonet]

Question from a newbie:

I would like to write a macro that return:

- the "caption" field of a tiddler if this field has a value

- the title of the tiddler if this tiddler doesnt have a caption field

Thx in advance for your help.

As per documentation:

"The content of the <$view> widget is displayed if the field or property is missing or empty."

Thus:

<$view field="caption">
   <$view field="title"></$view>
</$view>

enjoy,
