[Ken Ledeen]

THanks to all who have offered ideas.  I think the "bookpart" approach will
be quite effective for me.

I sincerely appreciate both the competence and the willingness to share of
this fantastic community.

That worked perfectly:

Re: FYI: recent MacPorts ghostscript upgrade causes Lilypond 2.24.2 warning from Guile

[Kenneth Wolcott]

Thanks, Jean, I wasn't sure that this was a different thing with
ghostscript or not, just thought I'd mention it.  Yes, I am using the
Lilypond tarball now in place of the MacPorts Lilypond.  I am looking
forward to the new Lilypond release...

Thanks,
Ken

[Jean Abou Samra]

Thanks, but we already know about this.
See https://gitlab.com/lilypond/lilypond/-/issues/6675 and the various recent
threads about Homebrew on this list.

We are unfortunately unlikely to convince package maintainers to downgrade
Ghostscript to 10.02.0 since the change that broke LilyPond was a security fix.

LilyPond 2.24.3 is going to be released quite soon with a workaround on our side
that should fix this issue. Meanwhile, it's best to use binaries from
lilypond.org.

[code excluded] ...

This is a really nice solution to compiling multiple movements, thanks!
One thing I noticed is that you get warnings about zero duration scores
when compiling less than the full piece.  To avoid this, you could add a
spacer rest to your EmptyBookpart variable like this:

EmptyBookpart = { s4 }

That gets rid of the warnings, but it also creates little scores with just
a clef and time signature.  It's a trade-off.  Personally, I don't want
spurious warnings in my LilyPond log, so I choose the spacer rest solution.

I am not calling lilypond directly from emacs, but a short script which
itself runs:

/usr/local/lilypond/current/bin/lilypond 
--include=/home/torsten/.lilypond/include "${@}"


Have fuun!

Ooh, ooh! A chance to share something that I've been taught here! ;-) Not
quite what you're looking for but it may give you ideas...

In my case, I have a lot of LilyPond files that I recompile too often --
mostly because I learn some more clever way of doing something and then go
back and change all of the old files. But, sometimes I want PDFs with a set
page size for printing, and sometimes I want SVGs with infinitely
long pages for the web. So a conditional based on an environment variable
which is set based on an argument to the Bash script. So, a conditional
expression and an include based on the value of the variable constructed:

%%%

% Use environment variable to decide if discrete pagination (PDF) or
% continuous pagination (SVG). Default to SVG if none defined.
%
pageBreaking = #(string-append (getenv "HOME") "/.local/lib/lilypond/"
(if (getenv "PAGE_BREAKING") (getenv "PAGE_BREAKING")
"svg") ".ily")
\include \pageBreaking

%%%
