snippet throws programming errors
Well, on my system your snippet as you have written it throws no error whatsoever... The result is exactly as I believe is the one you expected. I rather suspect your way of organizing the lilypond file is creating the error, or - perhaps more understandable - the fact that you are on a mac may be the reason? My own system is a linux debian testing, vigorously updated. -- yours, Villum Sejersen Nørregade 1 A DK-4500 Nykøbing Sjælland mobil +45 30 34 03 44 ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
Re: snippet throws programming errors
Grouping the key with the music is fine and gives no error (I’m using a Mac).
That’s reasonable since the key may change at places within the music.

snippet throws programming errors
The following snippet:
\version 2.19.15
music = \relative c'' { e2 g, }
\score {
\new Staff \key c \major \music
\layout {
\context { \Voice \consists Ambitus_engraver }
}
}
throws the following two programming errors:
* programming error: Note-column without heads and stem
continuing, cross fingers
* programming error: note-column has no direction
continuing, cross fingers
The pdf output looks perfect, so I guess the finger crossing worked.
These two errors can be eliminated in any one of several ways:
* eliminate \key c \major from the \new Staff statement (!!!)
* replace ... with {...} on the \new Staff statement.
* eliminate the \context statement in the \layout block
Where can I find out what's happening here? and is there a way to suppress
these errors similar to the way that warnings can be suppressed.

Your Staff line is equivalent to:
\new Staff
{ \key c \major }
{ \music }
Thus, there is no music in the first expression. In a nutshell, that
is what is causing your issue.
...
* replace ... with {...} on the \new Staff statement.
...
That is the correct solution, IMO.

throws the following two programming errors:
Programming errors are intended to report conditions that a programmer
thinks cannot happen in correct operation of the program. But with a large
program with large numbers of people working on it, what one programmer thinks
is an obviously-wrong situation might be considered a harmless null-case by
another programmer.
In this case, \key c\major is alone in its own voice with no notes, so the
Ambitus_engraver for that voice creates an ambitus with no note-heads,
but the note-column engraver thinks that an ambitus with nothing in it
must be an error.
Where can I find out what's happening here?
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=blob;f=lily/note-column.cc
and is there a way to suppress these errors similar to the way that
warnings can be suppressed.
I don't think so.
I would write
\new Staff \new Voice \key c \major \music
so that LilyPond's right hand doesn't fret about the empty voice for which
her left hand created an empty ambitus

Programming errors are only solved by correcting the program, not by avoiding them by modifying the input to the program. This is, of course, the cue for the rest of us to say : You've been using LilyPond longer than me; why haven't you yet corrected this serious problem !? You are suggesting that LilyPond is incapable of diagnosing a simple syntax error in its input. LilyPond is very accepting of varied syntax, makes up the missing parts, and in this case creates situations that other of its various spare-time programmers thought could only indicate an error. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
