Hi,
as asked on the -user list I am looking for a way to collect the
positions of all breaks in a LilyPond score.
http://lists.gnu.org/archive/html/lilypond-user/2015-01/msg00185.html
suggests that at the time engravers are doing their work the line and
page breaking hasn't been performed so engravers can't help with that.
But I'm quite sure LilyPond *has* a way to produce this information somehow.
The goal is to find a way to recompile just a certain page or system
using the skipTypesetting property, which works well for entering or
editing music as long as the changes don't require changed breakings
(which would then require a complete recompilation, resulting in a new
list of breaks.
So I have
a) the question if there already *is* a way to retrieve the moments
(barnumber plus measure-position) of all explicit and implicit breaks in
a score and write them to a log file?
b) if it's confirmed that currently there is no way to do so please add
this as a feature request to the tracker.
I hope to make this an editing option (in Frescobaldi, but it could be
adapted to other editing environments as well) that can dramatically
reduce waiting times while editing the *content* of a LilyPond score,
making the overall user experience significantly smoother. I hope that
this may significantly increase acceptance of LilyPond with potential users.
Best
Urs
