Re: where is the default auto-beam settings for 2/4 defined?
Frédéric Bron wrote Wednesday, September 02, 2009 6:18 AM Your remark is interesting! The doc says if they are some rules defined in auto-beam.scm, you MUST use #(override and #(revert... But only when the beam durations are the same. This is stated, maybe not very clearly, where I've indicated, here: "There are two mutually exclusive ways in which these rules may be modified. The first, modifying the grouping of beats, applies to uncommon time signatures, i.e. those for which there are no predefined rules defining the beam end points. The second method, modifying the specification of the beam end points, can be used for any time signature. This second method must be used for those time signatures and beam durations combinations for which beam ending rules are ^^ pre-defined, unless these have all been reverted. There are predefined rules for time signatures of 3/2, 3/4, 4/4, 2/4, 4/8, 4/16, 6/8, 9/8 and 12/8. " That's why the rules for 32nd notes don't affect 8th note beaming. Also see the comment in scm/auto-beam.scm just above this entry. This was very unsatisfactory, but auto-beaming has changed completely in 2.13, so the issue has already been addressed.

The doc says if they are some rules defined in auto-beam.scm, you MUST use #(override and #(revert... But it seams we can mix the 2 methods... extract of the doc in NR/1.2.4 Beams/Setting automatic beam behavior: "There are two mutually exclusive ways in which these rules may be modified.

In the following example, beams for 8 notes end at 1:4, 2:4, 3:4
and 4:4
but the only thing I can find in scm/auto-beam.scm about time 2/4
is:
((end 1 32 2 4) . ,(ly:make-moment 1 8))
((end 1 32 2 4) . ,(ly:make-moment 2 8))
((end 1 32 2 4) . ,(ly:make-moment 3 8))
How can I revert this rule to make 8 notes grouped by measure?
\version "2.12.2"
{ \time 2/4
#(revert-auto-beam-setting '(end 1 8 2 4) 1 4) % does not work
\repeat unfold 16 { c'8 }
}
I don't have the exact 2.12.2 version to hand,
but if scm/auto-beam.scm is as you say there
is no need to revert these settings as they
only affect 32nd notes. All you need to do is
to change the default beat-grouping:
\set beatGrouping = #'(2)
In version 2.12.1 (which I have to hand) there
is also a rule which affects all beams. This
will need reverting if it exists in 2.12.2 with
#(revert-auto-beam-setting '(end * * 2 4) 1 4)
