Your attempt can be simplified, see below. However, after having tried it
on a simple example, I'm no longer so convinced that it's a good idea, since
you typically might want the notes before the breath to be beamed together,
whereas the (equivalent of ) \noBeam removes the beam completely.
This means that you still will have to manually specify the start and
end of the beam.
% Alternative definition of \breathe that also does \noBeam
breathenobeam =
#(define-music-function (parser location) ()
(make-music 'EventChord
'origin location
'elements (list (make-music 'BreathingEvent)
(make-music 'BeamForbidEvent))))
% Using default \breathe
\relative c'{
c8 d e \breathe f g f e \breathe d }
% Using the new one
\relative c'{
c8 d e \breathenobeam f g f e \breathenobeam d }
% What you probably want typeset => \breathe and \breathenobeam are just
as bad
\relative c'{
c8[ d e] \breathenobeam f g[ f e] \breathe d }

Changing the default behaviour to always include the equivalent of \noBeam
is very easy, just add a line to the definition of \breathe in
ly/music-functions-init.ly
I tried to achieve it but it's the first time I write such an advanced function.
Can you please review it?
breathe=
#(define-music-function (parser location) ()
(make-music 'SequentialMusic
'origin location
'elements (list (make-music 'EventChord
'elements (list
(make-music 'BeamForbidEvent)))
(make-music 'EventChord
'elements (list
(make-music 'BreathingEvent))))))
{
c'8 \breathe d'
}
Making it customizable with a context property setting is slightly more
advanced
but can still be done in Scheme.
I have to confess I have no idea how to create the property (nor how
to name it :)
Since this will lead to an incompatible change of the default layout, I
would
propose to let convert-ly write out a warning about this change, if \breathe
is used in the file.
Yes... However, I'm happy to see that you regard it as a potentially
good idea ;)
Cheers,
Valentin
