Thanks, Knute. I am aware of those, but they don’t quite get me what
I want. If I hardcode the output directory with \bookOutputName, then
it can’t be overridden from the command line.
I'm not sure if this covers exactly your use case but should be easily
adaptable if not. Check the input and output file names. If they match
the -o option has not been used, in which case bookOutputName is called
to change the output file name.
\version "2.24.0"
#(let* ((opfile (ly:parser-output-name))
(ipfile (basename (ly:parser-lookup 'input-file-name) ".ly")))
(when (string=? ipfile opfile)
#{ \bookOutputName "newname" #}))
