Hello Valentin,
porting the scheme/LilyPond functions used by Spontini-Editor, in its internal library, from 2.18 to 2.19, would not complete the compatibility.
In fact, the editor relies on the SVG code generation too, which had changes during these years of LilyPond development.
Therefore, the only way that Saul could use to accomplish what he asked, is to convert his score from 2.18 to >=2.19.84 and then feed Spontini-Editor with the converted score.
Best,
P

Hello Saul,
in many cases a 2.23 ly file will be compatible with a 2.18 Lilypond.
The only problematic cases should be when Spontini uses overrides that did not exist in 2.18 (which shouldn't be that many) or if you are using music function that have changes names or syntax, which can also be amended by renaming the new ones to old ones or creating wrapper music functions, so you can have a few definitions that can simply be removed for 2.18.
But is there any reason for using such an old Lilypond version?
Cheers,
Valentin
