problems when final syllable has no notes

[eroux]

The following example:

\documentclass[a5paper, 12pt]{book}
\usepackage[autocompile]{gregoriotex}
\begin{document}
\gresetinitiallines{0}
\gabcsnippet{(c4) Ma(i)rí(kko>)a!(j.) R(::) Salve Mater.()}
\end{document}

produces the strange result:

I think this is because of the way \GreLastOfScore is handled...

[eroux]

(originally from this thread)

[eroux]

The problem disappears if \GreLastOfScore is not called before the bar, so I think it should probably not be output by gregorio in this case, but I'm not sure what the consequences would be on other edge cases... @henryso what do you think?

[henryso]

I'm not sure I'm the best person to opine on that, but I can try to make the change and see what tests it breaks. I take it this is for 5.0?

[eroux]

Well, I would prefer 4.2, but if you think this is too much, then 5.0 is fine

[henryso]

No, I can do it in 4.2, but the milestone is not set, so I wasn't sure.

[henryso]

From reading the description, I think this might conflict with #1116.

[henryso]

If the check is only for syllables that follow, this breaks (g) (Z), which would cause a dummy custos to be emitted at the end of the last line. As a result, I will check that there are no elements after the \GreLastOfScore element before suppressing it.
