Hans has mentioned several times that buffers are not going to be
written to files with luaTeX any more. This has a weird consequence on
many modules which relied exactly on that trick.
Short example of what goes wrong:
\starttext
\startbuffer[a]
Hello world!
\stopbuffer
\typebuffer[a]
%\executesystemcommand{dosomethingwith \jobname-a.tmp}
\stoptext
The problem is that MK II created a file \jobname-a.tmp and lilypond
module processed exactly that file further. In MK IV, that file is not
created any more (you can check that by running the above example with
--lua first and then with pdfTeX again. Only in the second case a file
[whateverthefilename]-a.tmp is created.)
Lilypond module relied on that "feature" (I would rather call it
dirty-but-very-useful-trick).
Hans, what's the current general recipe for this kind of [mis]use of buffers?
