Yes. TurboGears supports what is known as Buffet. Any template engine
that also supports that API can be easily used with TG (including yours).
You can find info about creating a Buffet adapter for your engine here:
http://projects.dowski.com/projects/buffet
If I were you I'd start by looking at the code for the simplest possible
engine, StringTemplate and using that as a foundation for your code:
http://projects.dowski.com/view/buffetstring
Once you've created your adapter you can simply use:
@expose ( 'myengine:mytemplate' )
...
assuming you've registered your engine under the name 'myengine' (which
I don't think I'd recommend ;-)
Another option is to simply return a string from your controller:
@expose ( )
def index ( self, *args, **kw ):
markup = render_template ( )
return markup
You may need to set some CherryPy response headers if you do this.
