Hi Peter,

I'm having a hard time to shorten your mail to the part I want to reply. 
I'd recommend to use plain text.
Right now I use the nabble-interface, because I failed to do it otherwise.
That's unneeded tedious.

Anyway, single Hairpins (not surrounded by other dynamic signs) should start
at the left of the starting note and end at the right of the target note. If
dynamic signs are present they are centered below their notes and the
Hairpin is printed in between. 
For subsequent Hairpins, end/new-start are printed a little left and right
from the corresponding notehead-center.
This is the typesetting rule as far as I can tell.

See LilyPond doing it:
\paper { ragged-right = ##f }
{ b4\> b\! }
{ b4\> b\> b\! }


Thus I think you're wrong saying
"Line 3 has the end of the hairpin too late."
And even your initial quoted statement is not at the lines of usual
typesetting rules.
The Hairpin _is_positioned correctly, although admittedly it looks terrible.
But this is due to the uneven spacing, not a wrong Hairpin.

Here: "Line 1 has the hairpin too late at both the start and endpoints" I'm
not sure what you want instead for the Hairpin-start, wherelse than after
the sforzato should it start? 
The endpoint is correct either (see above).
Alas, this line looks terrible as well.
By all means, the Hairpin is too short.

Similiar for line 2 of your example.

So, all these three examples look weird because the Hairpin is not long
enough.
This may be a weakness of LilyPond: A spanner doesn't push it's bounds,
unless forced. P.e. with setting minimum-length to a higher value. This is
not done automagically.

Thus line 4 looks best: The Hairpin is lengthened and positioned between the
two dynamic signs, each centerd below their notes. Although the uneven
spacing is still ugly.


So if you really want the Hairpin to end before the target note, you have to
ensure/set two things
(1) Help LilyPond, make the Hairpin long enough, i.e. set minimum-length to
a suitable value.
(2) For further tweaking use shortern-pair 

\paper { ragged-right = ##t }
{ 
\override Hairpin.shorten-pair = #'(0 . 1.5)
\override Hairpin.minimum-length = #10
b4\> b\! 
}


Cheers,
  Harm

Well, you could do like below, but I can't believe the output is what you
want.

\version "2.18.2"

createTuplet = #(define-music-function (parser location notes) (ly:music?)
#{
  \times 
#(cons 
  2 
  (length (extract-named-music notes '(RestEvent SkipEvent NoteEvent
  $notes
#})

{
  \createTuplet { c'4 e' r g' }
  \createTuplet { c'4 e' r  }
  \createTuplet { c'4 e' r s4 }
  \createTuplet { c'4 e' r s16 s16 s16 s16 }
}

Cheers,

For unknown reasons I don't see your posts on the mailing-list, thus
answering through the nabble-interface...

Probably below may do what you want, although I've no clue what you're
trying to achieve.
See the last example, strange, to say the least.

\version "2.19.65"

{
  \override NoteHead.stem-attachment =
#(lambda (grob)
   (let* ((stem-attach (ly:note-head::calc-stem-attachment grob))
  (stem (ly:grob-object grob 'stem))
  (stem-thick (ly:grob-property stem 'thickness))
  (layout (ly:grob-layout grob))
  (line-thick (ly:output-def-lookup layout 'line-thickness))
  (blot (ly:output-def-lookup layout 'blot-diameter))
  (stem-dir (ly:grob-property stem 'direction)))
 (if (and (ly:grob? stem) (< stem-dir 0))
 (cons 
   (- (+ blot (* stem-thick line-thick)) (car stem-attach))
   (- (cdr stem-attach)))
 stem-attach)))
  
  d'2
  g''2
  
  
}


HTH,
  Harm

Re: Chord Glissando Individual Voice right bound tweaking

[Thomas Morley-2]

dtsmarin wrote
> Thank you but the gliss. goes downwards whereas it should go upwards.

The code of my recent post wasn't meant to fix anything.
It is supposed to demonstrate the problem with a small (not even tiny)
code-example.

Though you may have noticed:
(1) Some aspects of the weird output are gone, because I deleted your
fix-attempts.
It would have been nice you inserted a comment like
"I tried

but to no avail"
(2)
It doesn't makes any sense to write
\override NoteColumn.glissando-skip = ##t \hideNotes r \unHideNotes
if you want to skip a column with the glissando.
Just use spacer, they don't cause a NoteColumn.

Furthermore I noticed some bugs, while continuing today on my small example:
https://sourceforge.net/p/testlilyissues/issues/4806/
  
https://sourceforge.net/p/testlilyissues/issues/4807/
  

You could have spotted them yourself, at least with a small/tiny example.
Some work or at least research on them already started.

Without bug-report no fix.

Please read the link I posted earlier again.
It's about compilable and minimal code and demonstrating the problem and
only the problem.
Yes this means some additional work and time for you.

Because I'm such nice guy I made your homework for you:

\version "2.19.38"

\layout {
  \context {
\Voice
\override Glissando.breakable = ##t
\override Glissando.after-line-breaking = ##t
  }
}

upper = 
\relative c'' { 
  \time 3/4 
  s2 
  \change Staff = "lower"
  4\glissando 
  \break
  \change Staff = "upper" 
  4
}

\new PianoStaff <<
  \new Staff = "upper" \upper
  \new Staff = "lower" { \clef bass s2. s4 }
>>

Took me 40 min.
In this time I could have worked on your problem.
I suggest you now do the work on my snippet above, I as a volunteer, don't
have time for it anymore.
Kitchen is calling.
