[stringtemplate-interest] [ST4] How to apply multiple "format"s to an expression?

[Collin Fagan]

*This could actually be done by extending the ObjectModelAdaptor model
adapter to have it check for such a method.*

Such an adapter is available as part of
STRUM<http://sourceforge.net/apps/mediawiki/project-strum/index.php?title=Main_Page>
.

   - PublicMethodModelAdapter<http://project-strum.svn.sourceforge.net/viewvc/project-strum/trunk/strum-project/strum/src/main/java/com/collinfagan/strum/adaptors/PublicMethodModelAdapter.java?revision=8&view=markup>-
access any public method from ST

Humm ... but it would be interesting to build a Renderer that took a
delimited set of format parameters.

<n;format="%15s,upper">

Of course comma works great here but not for the general case .. maybe make
the delimiter a parameter to the renderer? I might slap something together
to try it out.
