-st -x2 t -z +bx4 -x" Let us say you want a list, not a string. Do you want items like "-a -x3" to become separate elements? Then an additional usage of string-split could work. Although then you would have a list of lists. So in that case, you need to append the individual lists into one: (apply append (map (lambda (str) (string-split (regexp-substitute/global #f "(^-[^x]+)(x)" str 'pre 1 " -" 2 'post) #\sp)) (string-split "-y -ax3 +rx2 -stx2 t -z +bx4 -x" #\sp))) ("-y" "-a" "-x3" "+rx2" "-st" "-x2" "t" "-z" "+bx4" "-x") -- Aaron Hill

po \markup{ Allegro \notetest #4 }   c'1 } #4 is number?. The # signals an escape to Scheme syntax and the 4 is just an integer. 4 by itself could be parsed as ly:duration?, although you are are within \markup which might affect the parsing logic. -- Aaron Hill

((lambda (s) (if (string-prefix? "XX" s) (string-find-replace s "gg" "YY") s)) "XXssddffgghhjjkkll") "XXssddffYYhhjjkkll" Hopefully you can see that in this situation, regexp-substitute/global becomes the more succinct way to express things: (regexp-substitute/global #f "(^XX.*)gg" "XXssddffgghhjjkkll" 'pre 1 "YY" 'post) "XXssddffYYhhjjkkll" -- Aaron Hill
