Space between Lyrics and Stave, no paper effect related to remove "Bar_engraver"

Question

Using modern gregorian notation, I remove the bar engraver, but that causes that the space between Lyrics and next Stave shrinks. I want to increase the space between the Lyrics and next stave but the paper settings as suggested in other discussion has no effect system-system-spacing basic-distance and score-system-spacing I tried also verticalaxisgroup in layout, with no luck. Any workaround?

Answer 1

Apart from Knute’s remark on the wrong syntax for setting basic-distance this cannot work! That is because lyluatex needs to hand over the page breaking to LuaTeX. This is done by rendering each single system into a separate file and then arranging these systems on the page. This then allows LuaTeX to insert page breaks between such systems as it sees fit.

This means that to get such settings to work you must specify them from LuaLaTeX. You could either simply specify the line spacing by doing something \linespread{5}\selectfont before the Lilypond block, which will tell LuaTeX to put more space between these systems, or you can use the hook \betweenLilyPondSystem to do something like \newcommand{\betweenLilyPondSystem}[1]{\vspace{2em}\linebreak}.

If you want to include a complex layout with page geometry or multiple pages or something you can tell lyluatex to insert a page instead by adding the option insert=fullpage (so you’d do \begin{lilypond}[insert=...] ...).

Answer 2

When I tried your LilyPond source code, I assumed a version of 2.22.2, but even with lower versions your syntax for system-system-spacing is wrong. I tried this:

system-system-spacing.basic-distance = 20

...and the space between systems was very large.

Also, be sure when you post code that it engraves without any problems. Your code has some syntax for a document that is not LilyPond and causes errors.
