initio debilis with virga

[fradec]

In some rare cases initio debilis should be linked with a following virga, like this example:

It seems that none of the following tests make it possible.

% !TEX TS-program = LuaLaTex+se
\documentclass{article} %%
\usepackage[autocompile]{gregoriotex} %%
\begin{document} %%
\gabcsnippet{(c4) Iu(f)bi(f)lé(-fgv)mus(f)}
\gabcsnippet{(c4) Iu(f)bi(f)lé(@-fgv)mus(f)}
\gabcsnippet{(c4) Iu(f)bi(f)lé(-f@gv)mus(f)}
\end{document}

@fradec I've updated your comment so that it's more readable, look at the source (by editing it for instance) to see how I did it

[henryso]

This will require either drawing new glyphs or making the virga a possible ending to a fusion or both. @eroux How much time to we have before the TeX Live 2017 deadline?

[eroux]

Well, I admit I cannot remember exactly how things work, but we should have a new version on March 4th (can be beta1 or beta2 if we release it before), and we can aim say end of March for the definitive version...

[henryso]

Looking structurally at the font (though it's not semiologically-correct naming), these new glyphs would be "pes quadratum initio debilis", with various size queues. The executable will parse -fqg as this figure, though the glyphs are not currently being drawn. Drawing the extra glyphs is relatively easy, but I can go further and try to get the C code to transform -fgv into this glyph. Should I do that, or is -fqg sufficient?

[eroux]

Well, to me it looks like -fqg is sufficient... @fradec what do you think?

[fradec]

It's ok for me, it does not matter to have a different syntax for this kind of neumes, and the name proposed by @henryso is semiologically-correct I think, it can be also named "pes cassus initio debilis", it's the same. Thank's!
