Thanks for clearing that up. I'm happy to work on a patch that dumps a
"preview" of all systems, but I'm a bit stuck as to how. I'm looking at
'framework-svg.scm' here:
(define (output-preview-framework basename book scopes fields)
(let* ((paper (ly:paper-book-paper book))
(systems (relevant-book-systems book))
(to-dump-systems (relevant-dump-systems systems)))
(dump-preview paper
(stack-stencils Y DOWN 0.0
(map paper-system-stencil
(reverse to-dump-systems)))
(format #f "~a.preview.svg" basename))))
Is the first system being selected by the 'relevant-dump-systems' call?
That seems to filter through all systems looking for one with an "is-title"
property. What is the "is-title" property and when would a system have it?
As an aside, I'm finding it difficult to penetrate this code base. Any
suggestions on how to get started?
