Dear Harm,
You did it! You solved my problem, and have saved me from countless
tweak-recompile-tweak-recompile cycles with the way I was doing things
before. I can now set the vertical spacing of the chord/lyric lines in
relation to a single-line staff and move on, as I wanted. I am grateful
for the help you and others have given me on this issue.
I was experimenting with your solution, and I found a way to attach the
fixed chord-staff-chord group to other
Staffs/PianoStaffs/ChoirStaffs/StaffGroups, which retain their flexible
vertical spacing, and also retain flexible system-system spacing. I can
put the fixed-spacing staff group on top, anywhere in the middle, or on
the bottom of a grouping of staves.
Below, I have added some code examples. The examples use ChordNames
lines, but Lyrics lines work just as well. All of the fixed and flexible
vertical spacing can be adjusted in the \Score, \Staff, \ChordNames, or
\Lyics of \layout { \context ... }, and in \paper { ... }.
I noticed the following behaviors of the setting: \override
NonMusicalPaperColumn.line-break-system-details =
#'((alignment-distances . (1 2 3))). If you place this in \layout
{\context { \Score ...}}, then LilyPond will go through the list of
numbers in 'alignment-distances' creating fixed spacing between staves
from the top down until the numbers run out, then LilyPond will return
to the default or custom flexible vertical spacing settings for any
staves left over. This allows me to attach the chord-staff-chord
grouping on top of a staff, as in a leadsheet.
I wanted to see if I could get LilyPond to let me put the fixed
chord-staff-chord group in the middle of or at the end of a group of
Staffs/PianoStaffs/StaffGroups that have retained their flexible
vertical spacing. I tried putting NULL in the list of numbers in
'alignment-distances', and it worked! I think that any token that means
nothing to LilyPond can be used. If LilyPond runs into a meaningless
token/word, it will skip the fixed spacing for that staff-staff pair and
move to the next number/token in the list and the next staff-staff
spacing down the page. (I hope that I am using the terminology
correctly.) I do not know if the developers intended this or if it is
explained somewhere, but I like this behavior of 'alignment-distances'
and I hope it remains in future versions of LilyPond!
This tweak/technique is very useful to me, since a chord-staf-chord,
chord-lyric-lyric-lyric, chord-chord-chord, or any other grouping with
fixed spacing can be added to a score that retains its flexible spacing
on all of the other staves. You can also have a score that has a
flexible-fixed-flexible-fixed setup, by setting 'alignment-distances'
with the proper list of NULL-number-NULL-number tokens/variables that
correspond to the staves in the score.
I do not think your solution, nor this way of using
'alignment-distances' and NULL tokens, is readily apparent in the
documentation. (Of course, I could be missing something.) Perhaps, this
is another area where I could offer some patches to the documentation or
some snippets. I may share this in a blog article, eventually.
I can now get back to work on my manuscript projects. Thank you!
Peace,
David Froseth
P.S. I tried LilyPond 2.19.81 and the code worked, but the
superscripting in my custom chord symbols disappeared, so I am back to
using 2.18.2 for now.
