hm, only for testing, not for use
I can rotate boxes in ConTeXt using other methods than those used in
LaTeX. However, my main concern is about "translating" the Lua(La)TeX
piece to be used in ConTeXt. I've read about "finalizers" in the CLD
manual and somewhere online, but I don't know how to access to
node.subtype("pdf_literal"). I'll be happy to know about a better
solution if ConTeXt offers it so it is accessible to other users. Thank
you in advance.
The problem (or challenge) as usual is not in the coding but in what is
a reasonable user interface. So, what are the use cases. Her eis one
solution:
\protected\def\startvertical
{\dosingleempty\dostartvertical}
\def\dostartvertical[#1]%
{\begingroup
\getdummyparameters[width=\textwidth,height=\textheight,#1]%
\vbox
orientation 1
\doifelsedimension{\dummyparameter{width}}{to
\dummyparameter{width}}{}%
\bgroup
\doifelsedimension{\dummyparameter{height}}{\hsize
\dummyparameter{height}}{}}
\protected\def\stopvertical
{\vfill
\egroup
\endgroup}

\stopvertical

But it's kind of a quick hack interface. We can have alignment,
interlinespace etc parameters to. Maybe definable verticals and so.

ps. for chinese one would probably kick in an extra feature
% \definefontfeature
% [vertical]
% [vertical={%
% orientation=3,%
% down=.1,%
% right=.1,%
% ranges={%
% cjkcompatibility,%
% cjkcompatibilityforms,%
% cjkcompatibilityideographs,%
% cjkcompatibilityideographssupplement,%
% cjkradicalssupplement,%
% % cjkstrokes,%
% cjksymbolsandpunctuation,%
% cjkunifiedideographs,%
% cjkunifiedideographsextensiona,%
% cjkunifiedideographsextensionb,%
% cjkunifiedideographsextensionc,%
% cjkunifiedideographsextensiond,%
% cjkunifiedideographsextensione,%
% cjkunifiedideographsextensionf,%
% }%
% }]
and maybe some extreme hz would work out well too.
