I have an arbitrary field on several tiddlers, called bgimage. It
references a background image.
In ViewTemplate, I have defined a macro (immediately after where
frame-classes is defined):
\define bgstyle()
background-image:url(<$transclude field='bgimage'/>);
\end
If I call <<bgstyle>> (again, in ViewTemplate) as content of my tiddler, it
works like I'd expect. It pulls the value from the bgimage field and writes
it in.
But, if I call it within the <div> tag, like so:
<div class=<<frame-classes>> style=<<bgstyle>>>
...it comes through unrendered, as a literal (the raw string,
"background-image:url(<$transclude field='bgimage'/>);" instead.
Why does the macro get expanded in the content but not within the div
element?
I get the sense that if I understood that, I'd understand TiddlyWiki a lot
better.
Can anyone explain this behaviour and suggest how this ought to be done?
Thanks!
