Hello everybody,
personally I increasingly feel like I kind of need these inspirational
posts about the power of LilyPond, so here’s one of my own: I love how
with the attached library file [ly-utility.ily], \include-d in
[standard-include.ily], I can just add the following short lines at the
top of my input file:
%%%%%%%%%%%%
\include "standard-include.ily"
transposer = \transpose es as \etc
\addToplevelMusicFunctions transposer
%%%%%%%%%%%%
and all the subsequent music will be transposed without the need to
insert anything into any \score {}.
Best,
Simon
PS: Anticipating the question: I think \addToplevelMusicFunctions is in
this form or another a candidate for openlilylib, if not even for the
main code base.
\version "2.19.53"
musicFunctionDummy = #(define-music-function (mus) (ly:music?) mus)
addToplevelMusicFunctions =
#(define-scheme-function (names) (symbol-list-or-symbol?)
(let* ((name-list (if (list? names) names (list names)))
(lookup-function (lambda (name) (let ((fn (ly:parser-lookup name)))
(if (equal? fn '())
musicFunctionDummy
fn))))
(fn-list (map lookup-function name-list)))
(set! toplevel-music-functions (append fn-list toplevel-music-functions))))_______________________________________________
