doesn’t deceive me, there are seven commands which output
context-spec-music.
It’s currently possible to use these on top level:
%%%%% \version "2.19.27"
\melisma
%%%%%
It's possible to use any music variable at top level.
gives no warning or other message, but the attached (nonsense) output.
This becomes a problem when ")" has been redefined and somewhere else
a Scheme expression has mismatched braces:
%%%%% \version "2.19.27"
")" =\melismaEnd
#(define test "foo"))
%%%%%
An extremely annoying case to debug, I can tell you.
So redefining ")" should not preclude the warnings which turn up
without the redefinition.
What warnings? You are talking about an error here:
/tmp/riga.ly:1:1: error: syntax error, unexpected EVENT_IDENTIFIER
and that error is based exclusively on the _content_ of ")" and not
related to any independently produced warnings. For example, you can
write \] and just get
/tmp/riga.ly:1:1: warning: cannot find start of ligature
Making an error based on context-spec-music would be quite strange, by
the way, since _many_ toplevel expressions are context-spec-music, like
\new PianoStaff ...
