PS-HTML is indeed what I wanted, or almost (see below). I'm glad this discussion came up. By the way, the documentation page you linked to, which I hadn't looked at in a long time, is very nice.
I pushed two small patches to the repository to make PS-HTML do what we need:
1. Use the string-buffer-join technique for concatenating HTML at runtime, since the + operator is notoriously slow when the strings aren't small, at least in older browsers.
2. Expanded the amount of compile-time constant folding of strings that PS-HTML is able to do. For example, if you give it a character, or an expression that macroexpands to a string, these are now joined in with the string literals PS-HTML emits. Apart from reducing the amount of joining needed at runtime, this makes the emitted HTML more readable.
If either of these strikes anyone as inappropriate, speak up so we can figure it out together.
I'm glad we had this discussion. I did not want to write yet another sexp-html library.

Not at all, I forgot about it. I think it didn't do what I wanted way back when, but I'll check it out again and report back. Thanks for reminding me.

Parenscript has always had an s-expr HTML markup generator ( http://common-lisp.net/project/parenscript/reference.html#ssection-html-gen ). Or am I being dumb and you're talking about something else?

2010/6/20 Daniel Gackle danielgackle@gmail.com:
If I understand correctly, your problem is that you want to express HTML in sexprs à la CL-WHO but with inlined PS expressions to dynamically change what gets emitted. Since you want PS expressions, you must be generating this HTML at runtime in the browser. Is that right? It so happens that I got frustrated with doing the same thing yesterday and wrote a macro to allow me to inline HTML inside PS in this way. Before I post it, though, I want to make sure it at least covers all our existing cases. Can other people pipe up and explain what they do to generate HTML from PS? Is there currently a standard solution better than "<div>"+blah+"</div>"? Daniel
