I don't think that using a new spacing section is the right way to
solve this because such a section could still be compressed
unfavorably in tight situations, AFAIK. Instead, I would simply give
the glissando line a minimum length (I use an exaggerated value for
demonstration purposes).
```
\relative c'' {
\time 3/4
\override Glissando.style = #'zigzag
c4 c4
c4*7/8
\tweak springs-and-rods #ly:spanner::set-spacing-rods
\tweak minimum-length #10
\glissando
\hideNotes c,,32 \unHideNotes
\bar "|"
R2.
}
```

Thank you - that works well, to enable the glissando to have more space
I added a new spacing section around it giving this example:
8><8><8><8><8><8><8><8><8><8><8><8><8><8><
\version "2.25.18"
\relative c'' {
\time 3/4
\override Glissando.style = #'zigzag
c4 c4
\newSpacingSection
\override Score.SpacingSpanner.spacing-increment = #1
c4*7/8\glissando
\hideNotes c,,32 \unHideNotes
\newSpacingSection
\revert Score.SpacingSpanner.spacing-increment
\bar "|"
R2.
}
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
If someone is updating it might be good to include this tweak as
otherwise the end of the glissando is restricted to staying within the
space occupied by the note.
Thanks to all who responded!

So one or other of those should replace the original example
in NR that is decidedly long in the tooth, dating from 2.12.0.
(Particularly as the original one doesn't really work.)

The \after command solves this problem: say you have this music:
{ c'2. c'4 }
...and you want to add markup text to the second beat. There is no note on
the second beat, so you would write:
{ \after 4 ^\markup "A" c'2. c'4 }
That is, after a duration of 4, add ^\markup "A" as if a note were there.
Now in the case of the glissando, you really don't need \after, you could
just write:
\relative c'' {
\time 3/4
\override Glissando.style = #'zigzag
c4 c4
c4*7/8\glissando
\hideNotes c,,32 \unHideNotes
\bar "|"
R2.

This looks promising and I would like to try to understand what the two
duration parameters 8.. and 32 are doing in this context.
The only documentation I have found for \after is
\after delta (duration) ev (music) mus (music) ⇒ music
Add music ev with a delay of delta after the onset of mus
I'm not sure what "Add" means here - playing around with various values
has got me confused - some values push subsequent notes into the next
bar, others change the spacing of bars before and after as if it had
affected the Score.SpacingSpanner.spacing-increment.
I wonder if someone could shed some light on this. The goal is to
create a glissando from a note to a non-printing note - I'm this means
its note-column (?) is made wider, but otherwise the spacing is normal.
Many thanks,
Richard

(firstly, apologies for the typo - it should have been R1*3/4 for the
whole measure rest)

Well, the case arose in a large orchestral score, but as the problem is
visible when just adding a whole measure rest to the example in the
docs it seemed best to ask about that.
>

Thank you! That inscrutable "s" added fixes that case. But I see that
further trouble sets in as the score gets more complex with more staffs
so the solution proposed by Yoshi would seem to be the way to go.

Hello Richard and David,
Here is what I had, fyi. I used \after function to give the glissando some fine
tuning while the content of the measure not spilled over to the next measure.
While I could see the rationale behind using \cadenzaOn and \cadenzaOff, I fear
that it affects the overall spacing. For glissando of this kind, I think that
it is best to keep the issue of spacing as intact as possible. So my example
doesn’t use the \cadenza… functions.
All the best,
Yoshi
