Use the format procedure. You can read more about the format procedure at the Guile reference manual: http://www.gnu.org/software/guile/manual/html_node/ Formatted-Output.html#Formatted-Output LilyPond uses a simplified version of the format procedure to reduce calculation time. If the output you want is not supported by the lilypond format (roman numerals, for example), you can get the full format procedure in lilypond by calling fancy-format. stopwatch = #(define-music-function (parser location minutes seconds) (integer? integer?) "Put the time given by @var{minutes} and @var{seconds} in a rounded box." (let ((pretty-seconds (format #f "~2,'0d" seconds)) (minutes-string (number->string minutes))) #{ \mark \markup \rounded-box \small \concat { $minutes-string \char ##x2032 $pretty-seconds \char ##x2033 } #})) { c'1 \stopwatch #4 #3 c' \stopwatch #2 #45 c' } HTH, Carl _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
