Wow, thanks, this is a nice solution! So the "conditional-compile.ly" file is the child file (for a single movement) and the "conditional-compile2.ly" file is the parent file (that contains several movements). Below is a version of "conditional-compile.ly" where I added some logging commands if that helps anyone else see how it's working. Your "doScore" function seems to be a workaround for the limitation that music functions can't return a score. (I tried to rewrite it as a music function but got "error: music function cannot return #<Score>". I think this would be a nice standalone snippet for the LSR or openLilyLib. And I need to take a closer look at your lalily template system and edition engraver. Thanks, -Paul BTW, if anyone is wondering what "smob" refers to, for example in "parser-smob" in the docs, I found this ("small object"): https://www.gnu.org/software/guile/manual/html_node/Defining-New-Types-_0028Smobs_0029.html#Defining-New-Types-_0028Smobs_0029 %%%%%%%%%%%%%%%%%%%% % "conditional-compile.ly" \version "2.18.2" #(use-modules (ice-9 regex)) #(define (lalily-test-location? parser location) (let ((outname (ly:parser-output-name parser)) (locname (car (ly:input-file-line-char-column location)))) (display "1.
