First of all, thank you for a nice library.

You're welcome... :)

Now, I have a question. Is there a way to have html-template call back into the calling environment so I don't have to pass all slot values of a list of objects in as a list?

So instead of:

;;; prints "b c" (fill-and-print-template "<!-- tmpl_loop ... -->" (list :a (list :b "b" :c "c")))

I can do something like:

;;; prints "b c" (fill-and-print-template "<!-- tmpl_callback (b-of a) --> <!-- tmpl_callback (c-of a) -->" (list :a a))

Where b-of and c-of are readers. It is just very very tedious to make lists of all the values.

Does that make any sense?

Not for me. The design goal of HTML-TEMPLATE is to be as simple as possible - the idea is that the people working on the HTML don't have to learn yet another programming language. I don't understand why you can't achieve what you want within Lisp, something like (fill-and-print-template "<!-- tmpl_loop ... -->" (my-function a)) where MY-FUNCTION builds and returns the structure you need. Edi.
