This example illustrates some of the pitfalls of using text substitution with
macros:
* It will fail if the tiddler title contains ]], }} or !!
* or if it ends with a single !
* or if it contains a single quote
* It will fail if the caption contains a vertical bar | or double closing
square brackets ]]
An alternative implementation might be:
\define image(tiddler)
<$tiddler tiddler=<<__tiddler__>>>
<$image source={{!!title}} width=80 tooltip={{!!caption}}/>
</$tiddler>
\end
<<image "Motovun Jack.jpg">>
There are several points:
* using the <$tiddler> widget to reference the image tiddler so that we can use
text references to refer to the fields
* using the ability to refer to macro parameters as variables by wrapping it
with double underscores
* using the <$image> widget rather than the shorthand syntax
Best wishes
