Yeah, functionality like you describe, with the quadruple round bracket, would be good for having the flexibility when needed.
I thought about it and I wonder if there's a way to just have the parser combine (string literal concatenation) sibling nodes of the parse tree when they're both string literals. That way both the string literal and the wikified transclusion would be mashed together. That way it could be: <a href="http://google.com/#q="{{!!x}}>link</a> becomes <a href="http://google.com/#q=""value of field x">link</a> becomes <a href="http://google.com/#q=value of field x">link</a> As an alternative, would it be possible to add a layer of recursion so that any block which gets wikified is reparsed (and rewikified) until it doesn't change? That would probably create lots of side issues, but it would allow nesting of widgets, etc. Thanks for your excellent response. I apologize if the questions or suggestions I have show my ignorance of how TW works under the hood. -Mike On Monday, February 3, 2014 3:41:02 PM UTC-5, Jeremy Ruston wrote: > > Hi Mike > > Going back to your original question, consider the example you gave: > > <a href="mailto:<$view field="email">">click to email</a> > > At the moment, that doesn't work because the double quotes on the href > attribute cause the value to be interpreted as a literal string.
