Hi Ron,
You can use the with-html-output-to-string function to generate HTML at run-time. Using it in a macro, you can then do data-driven HTML construction using mapcar, loop, etc.

Is there a Right Way to use CL-WHO to generate HTML at run time? For example, suppose I want to do something like this:
(defun make-table (l) `(:table ,@(mapcar (lambda (row) `(:tr ,@(mapcar (lambda (cell) `(:td (str ,cell))) row))) l)))
(cl-who:with-html-output-to-string (*standard-output* nil :prologue t) ... (make-table l) ...)
This doesn't work because CL-WHO normally does all its work at compile time, but L is not known until run time. I can hack this using a macro that calls EVAL, or by hacking the CL-WHO code to add another specially handled symbol, but before diving into that rabbit hole I thought I'd ask if there was already a way of doing this that I've overlooked.
Thanks, rg
