I now come up with (only markup again):
#(define-markup-command (dyn-test-II layout props strg)(string?)
#:properties ((reg-exp "\\{[^{}]*\\}")
(separators (char-set #\{ #\}))
(dynamcs (char-set #\f #\m #\p #\r #\s #\z)))
(interpret-markup layout props
(make-line-markup
(map
(lambda (s)
(let* ((matches (list-matches reg-exp s)))
(if (null? matches)
s
(let* ((poss-dyns (map match:substring matches)))
(append-map
(lambda (p-d)
(let* ((cand (string-trim-both p-d separators)))
(if (string-every char-set:dynamics cand)
(make-concat-markup
(list
(make-concat-markup
(map match:prefix matches))
(make-dynamic-markup cand)
(make-concat-markup
(map match:suffix matches))))
p-d)))
poss-dyns)))))
(string-split strg #\space)))))
\markup \dyn-test-II #"poco {f}, but {p} sub. {ma} non troppo"
Though, if I split the string anyway (splitting at #\space should do
no harm, imho), it's probably cheaper to go for string-match instead
of list-matches.
Not sure...
Cheers,
Harm
