Hi, Eric,
Thank you, though I'm afraid I'm still having trouble getting
the right result. The closest I've come is with this setting:
(setq org-babel-tangle-comment-format-beg
"\\sourcefilename \"%file\"\n\\sourcefileline %start-line")
But this adds comment characters before the commands.
It also adds a blank line after the comment, throwing line numbers
off by one. (Actually they are off by two; maybe LilyPond needs
\sourcefileline to be on the same line as the beginning of the code.)
By the way, I tried binding the variable this way in the Org file:
#+BIND: org-babel-tangle-comment-format-beg "\\sourcefilename
\"%file\"\n\\sourcefileline %start-line"
But that had no effect.
A further question: can this approach accommodate code blocks in
multiple languages in the same file?
Best,
Thomas
