I have the code listed above and I am wondering how I can get CJK text to be in a vertical form (along with Vietnamese. I know l2r as an option exists in startalignment, but there seems to not be a vertical equivalent for vertical text. How do I achieve this?
there is something mentioned in followingup-directions.tex
i removed top to bottom directions from luametatex because it made no sense; one cannot do vertical typesettign without also looking at the layout and other things
instead of directions we do rotation at the glyph level and such which has less interference and more flexible
but ... i haven't looked at it recently (could be broken by other features) as there is little demand for it

For japanese, I think that the only reference for luatex (actually lualatex) is https://ctan.org/tex-archive/macros/luatex/generic/luatexja -- luigi
