Re: Hairpin-end/dynamic-mark collision at barlines

Hi Connor,

thanks for well written your report.
Some details:

This is intended behaviour, at least the shortening. You may want to
improve those cases by overriding minimum-length.
\override Hairpin.minimum-length = #8 %% or what ever value fit your needs.
Tbh, those cases are a steady nuisance and waits for improvement...

The vertically displacement, (3) of your code, is indeed strange.

All other listed case can be done by applying a (correct)
tweak/override for 'to-barline.
\override Hairpin.to-barline = ##f

Nope.
Your tweak:
\tweak to-barline ##f g1\>
is placed wrongly, so it can't work.
Try:
g1-\tweak to-barline ##f \>

Or use the override as shown above.

Sumary:
Case (3) may be a bug or not, I'm not sure yet.
All other is intended or known or may be worked around quite easily.
