You are changing behavior rather deep in the details.
You can search for stencil-offset in the setup files to see an example
of its use. In define-grobs it is used for a dyanmics spanner. It is
a pair of numbers, probably X and Y:
\relative c'{
\override TextSpanner.bound-details.left.stencil-offset = #'(0 . -0.5)
\override TextSpanner.bound-details.right.stencil-offset = #'(0 . -0.5)
\override TextSpanner.bound-details.left.text = #"ggg"
\override TextSpanner.bound-details.right.text = #"hhh"
c4^\startTextSpan c c c \stopTextSpan }

Really? Then why do these texts not align along their baselines:
The default settings have the same minimum gap between staff and text,
including descenders, as the minimum space from staff to the baselines. So the
padding against collisions is all we see.
We can change the settings, increasing the space to the baseline:
http://lilypond.org/doc/v2.18/Documentation/learning/fixing-overlapping-notation#the-staff_002dpadding-property
{\textLengthOn
\override TextScript #'staff-padding = #1
c''^\markup { NO DESCENDERS!! }
c''^\markup { jjjyyyjjjggg } }
(There are some other things -- tempo marks, I think -- where the code makes so
many adjustments to placement that I could not figure out how to uncover the
simple behavior of spacing to the baseline.)
I think it would be better to move the reference line to half the x-height of
the font above the baseline (as it is now for the p, f, etc., letters in
dynamics) for any text near music.
Then the same distance from staff to reference line would make sense for items
both above and below the staff,
and it would be simpler to center lyrics between staves (no longer needing to
adjust distances by that half an x-height).

Hi Keith,

Really? Then why do these texts not align along their baselines:
\version "2.19"
music = {

Hi,
in the attached image you see a TextSpanner, and I'm having some issues
with it:
- why is the first dash longer than the other(s),
is this a design decision (if yes, why)?
can it be modified?
- is it possible to make a TextSpanner always to align
to the right edge of the score (i.e. the barline)
and let the dash structure adapt to that?
(I see the 'right-bound-info' property but didn't
find any helpful information on that alist)
- is it possible to tweak
- the attachment of the first dash to the text and
- the vertical position of the dashes (i.e. raise
it a little bit relatively to the text)
?
Thanks for any explanation or ideas
Urs
Hi Urs,
You can change the look of the dashes (add your own numbers) ...
\override TextSpanner.dash-period = #0.8
\override TextSpanner.dash-fraction = #0.2
Yes, I know
(I think that was already visible in the attached image ;-) )
and you could add a space after "rit.". ie. "rit. ".
or maybe...
\override TextSpanner.bound-details.left.text = \markup { "rit." \hspace
#0.5 }
OK, this works (even as
\markup { \concat { $text \hspace #0.5 } }
inside a function.
Although I find it a bit hacky ...
You could also superscript a space after "rit." which would raise the
dashed line, or maybe use \vspace or \raise.
Hm, neither \super, \vspace nor \raise seems to have any effect on the
dashes.
Don't know if that helps?
As said, partially.
Thanks
Urs
Phil.

I was just rambling. I'm thinking that the logic of that command might be extended to an actual enhancement of LilyPond to make such things automatic, but I don't have a good answer to how to achieve what you want with LilyPond as it is. I imagine you could create a markup command, but a better option may be a custom stencil function for TextSpanner which could deal with broken spanners. -David ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

I can't see any reason why LilyPond couldn't be enhanced to ensure that this doesn't happen. Yes, I think that the overall extent of the spanner should (optionally) be favored against the literal dash structure. Actually LilyPond wouldn't (AFAICS) end the spanner with a dot, but rather with a gap (which isn't nice either). In fact, there's a markup command \draw-dashed-line which guards against these clipped edges. You mean I should replace the TextSpanner by a custom \markup command?
