Error in lilypond-Log: "/bin/sh: 1: Syntax error: Unterminated quoted string"

[Luensche]

Hello,

I am trying to use lyluatex but already fail in the beginnings.

This is my MWE:

% !TeX program = lualatex
\documentclass[
ngerman
]{scrartcl}
\RequirePackage{luatex85}
\usepackage{babel}
\usepackage{graphicx}
\usepackage{emerald}
\usepackage{geometry}
\usepackage{luacode}
\usepackage{luaotfload}
\usepackage{fontspec}
\setmainfont{Noto Sans}
\geometry{a4paper,left=20mm,right=20mm,top=20mm,bottom=20mm}
\usepackage[pass-fonts]{lyluatex}

\begin{document}
\lilypond{ c' d' e' }
\end{document}

When I execute lualatex -synctex=1 -interaction=nonstopmode -shell-escape "mwe".tex I will find the following passage in my log file:

Module lyluatex Info: Compiling score tmp-ly/fc20691fa92c1ef1cd34040369dc610f wi

The lua interpreter ran into a problem, so the
remainder of this lua chunk will be ignored.

So I had first a look into tmp-ly/fc20691fa92c1ef1cd34040369dc610f.log. It shows only one line:
/bin/sh: 1: Syntax error: Unterminated quoted string
Up next, I looked into the generated LilyPond file which looks fine:

%%File header
\version "2.18.2"

#(define inside-lyluatex #t)
#(set-global-staff-size 12.166663275825)
#(set! paper-alist (cons '("lyluatexfmt" . (cons (* 597.507874 pt) (* 845.046844 pt))) paper-alist))

\include "lilypond-book-preamble.ly"

\header {
    copyright = ""
    tagline = ##f
}
\paper{
    #(set-paper-size "lyluatexfmt")
    two-sided = ##f
    line-width = 483.69686889648\pt
    indent = 0\pt
    % no alignment set
    #(define fonts
    (make-pango-font-tree "Noto Sans"
                          "Latin Modern Sans"
                          "Latin Modern Mono"
                          (/ staff-height pt 20)))

}
\layout{
    % no clef set
    % timing not suppressed
    % no time signature set
    % staff symbol not suppressed
    % no fix for badly cropped StaffGroup brackets
}

%%Follows original score
{c' d' e' }

So I executed lilypond fc20691fa92c1ef1cd34040369dc610f.ly. This produces the normal files. For me, it seems that there is an error in lyluatex. But I couldn't find it on a first look at the source.

OS: Ubuntu 22.04
TeX: MikTeX 23.5
LilyPond: 2.22.1

May you please try with debug option ?

\usepackage[debug,pass-fonts]{lyluatex}

Now the log contains the following:

Shouldn't be the command the following?

"lilypond" -E -dno-point-and-click -djob-count=2 -dno-dele
te-intermediate-files -I ".\" -I "/home/bjoern/Downloads/tmp/Lua/" -o "tmp-ly/62

If I run "lilypond" -E -dno-point-and-click -djob-count=2 -dno-delete-intermediate-files -I .\ -o "tmp-ly/624d513bb9296e3eafb63884d8ab98be" tmp-ly/624d513bb9296e3eafb63884d8ab98be.ly 2>&1 directly in the shell, it produces an eps-file as output.

I changed a few lines in lyluatex.lua and not it works for me.
The changes can be found here.
