I would write #(shape-slur offsets) here: there is no need for an immediate Scheme expression here (the point of $ over # is that the syntactical function of the $ expression is determined by its expression type, but here the syntactical function needed is "Scheme" anyway). > Variables in musicfunctions now are available by there name without > the preceding $. > The $-sign now introduces a scheme-expression and returns the result > directly ... now here should be more explanation, that I am not able > to put in words right now ;-) $some-expression is equivalent to \name if you had written name = #some-expression some times earlier where an assignment is allowed. Actually, whenever name is a valid LilyPond identifier name as well as a valid Scheme identifier name, $name and \name are perfectly equivalent. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
