Using LuaLaTex with Mac TeXLive 2020 and LilyPond 2.20 (was: Spacing of systems while using lyluatex)

[Jacques Menu]

Hello folks,

Thanks to Samuel and Fernando, I’ve been able to set these two 
Lua*TeX+se.engine files on Mac OS Mojave, taken from 
https://github.com/gregorio-project/gregorio/tree/master/contrib/TeXShop:

menu@macbookprojm: ~/Library/TeXShop/Engines > ls -sal

0 drwxr-xr-x  10 menu  admin   320 Aug 26 18:05 .

menu@macbookprojm: ~/Library/TeXShop/Engines > cat LuaTeX+se.engine 
#!/bin/bash

if [[ -n ${2:+x} ]]; then
    echo "I will add $2 to the input path"
    export TEXINPUTS="$2//:"
    export LUAINPUTS="$2//:"
fi
luatex --shell-escape -file-line-error -synctex=1 "$1" 


menu@macbookprojm: ~/Library/TeXShop/Engines > cat LuaLaTeX+se.engine 
#!/bin/bash

if [[ -n ${2:+x} ]]; then
    echo "I will add $2 to the input path"
    export TEXINPUTS="$2//:"
    export LUAINPUTS="$2//:"
fi
lualatex --shell-escape -file-line-error -synctex=1 "$1" 


Then my test file, attached, is handled alright - see below.

Hope this helps others!

JM
