Comment #5 on issue 2872 by [email protected]: Patch: Provide define-session and
define-session-public commands
http://code.google.com/p/lilypond/issues/detail?id=2872
As a test, I used
#(display instrument-equalizer-alist)
#(set! instrument-equalizer-alist
(append
'(
("flute" . (0 . 0.7))
)
instrument-equalizer-alist))
and called lilypond xxx.ly xxx.ly. The second run of the file produced a
longer output. Then I replaced (define-public
instrument-equalizer-alist '()) in scm/midi.scm with (define-session-public
instrument-equalizer-alist '()) and the output of the first iteration
through the file remained identical while the second run also produced the
same result.
Obviously, this will require followup work to identify data structures that
should be session-only. But at least the infrastructure now is there.
