[plt-scheme] Conditions in web-templates

Yes. Here is an example:

if.html:
@(if (@monkeys . > . @monkey-limit)
     @list{<p>There are too many monkeys!</p>}
     @(if (@monkeys . < . @monkey-minimum)
             @list{<p>There aren't enough monkeys!</p>}
             @list{<p>There are just enough monkeys!</p>}))

http://svn.plt-scheme.org/plt/trunk/collects/tests/web-server/template/examples/if.html

run.ss:
(define (if-template #:monkeys monkeys
                     #:monkey-limit monkey-limit
                     #:monkey-minimum monkey-minimum)
  (include-template "if.html"))

(if-template #:monkeys 5
             #:monkey-limit 10
             #:monkey-minimum 2)
(if-template #:monkeys 11
             #:monkey-limit 10
             #:monkey-minimum 2)
(if-template #:monkeys 1
             #:monkey-limit 10
             #:monkey-minimum 2)
