[stringtemplate-interest] Renderer "modes"

[Jeremy Gray]

I think I'm starting to see where you're heading with this. I haven't
had a chance to look into the behaviour of overriding the method you
mention, but if you're talking about the SetAttribute I think you're
talking about then I'm not sure whether or not it will do the trick.
That said, I'd best just take this issue away and play with it for a
while rather than ramble to the mailing list about things I haven't yet
tried. :)

I'm pretty sure that that same section shows subclassing to override  
setAttribute.  My cutpaste stopped at the spot.

If the wrapper has two methods, getMedium and getVerbose, then you  
can have templates say:

$mydate.medium$
$mydate.verbose$

The first calls getMedium() on the wrapper which formats the data  
held in that object.

Does that help?
