Re: [NTG-context] About vertical typesetting in ConTeXt
Thank you a lot, Hans. Indeed, the second solution seems to correctly put
text into a vertical flow. However, a serious issue with Mongolian script
is the horizontal direction: unlike CJK vertical typesetting, the text
columns go from left to right, and the following almost works (\definefont
gives no ligatures in my computer so I've used \definefontfamily instead)
%\definefont does not work as expected
\definefontfamily[main][serif][mongolianwhite][features=mongolian]
\setupbodyfont[main,24pt]
\defineframed
[vertical]
[
offset=none,
align=flushleft,
anchoring=left,
foregroundstyle={\setupinterlinespace[40pt]}]
\starttext
%\MyFont
\startframed[vertical]

I've attached two files: the ConTeXt output (results so far) and the
expected result (done via LuaLaTeX). As it can be seen, the text lines
should go "upwards". I'd just use LuaLaTeX for this specific case, but
ConTeXt is too cute...
Thank you again, Hans.
Sincerely,
Jairo.

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]%

\getdummyparameters[width=\textwidth,height=\textheight,#1]%

But it's kind of a quick hack interface. We can have alignment,
interlinespace etc parameters to. Maybe definable verticals and so.
Hans
ps. for chinese one would probably kick in an extra feature
% \definefontfeature
% [vertical]
% [vertical={%
% orientation=3,%
% down=.1,%
% right=.1,%
% ranges={%
% cjkcompatibility,%
% cjkcompatibilityforms,%

and maybe some extreme hz would work out well too.

Re: [NTG-context] About vertical typesetting in ConTeXt
Hi, list. I've found a (sort of) way to do LTL typesetting in Lua(La)TeX
based on "chickenize", a LuaTeX package. The font used is available here;
http://www.mongolfont.com/en/font/mnglwhiteotf.html
%Just for testing in LaTeX
\documentclass{article}
\usepackage{luacode}
\usepackage{fontspec}
\setmainfont{Mongolian White}[Renderer=Harfbuzz,Script=Mongolian]
\begin{luacode*}
-- How do I do this in ConTeXt?
userdata = userdata or {}
userdata.mongolian = function(head)
--Ugly hackish line rotation
rot = node.new(node.id("whatsit"),node.subtype("pdf_literal"))
rot2 = node.new(node.id("whatsit"),node.subtype("pdf_literal"))
for line in node.traverse_id(0,head) do
w = line.width/65536*0.99625
rot.data = "-1 0 0 -1 "..w.." 0 cm"
rot2.data = "-1 0 0 -1 "..-w.." 0 cm"
line.head = node.insert_before(line.head,line.head,node.copy(rot))
node.insert_after(line.head,node.tail(line.head),node.copy(rot2))
end
return head
end
\end{luacode*}
\def\startmongolian{\directlua{luatexbase.add_to_callback("post_linebreak_filter",
userdata.mongolian, "mongolian")}}
\def\stopmongolian{%
\par\directlua{luatexbase.remove_from_callback("post_linebreak_filter",
"mongolian")}%
}
\usepackage{graphicx}
\begin{document}
\rotatebox{90}{%
\parbox{8cm}{%
\startmongolian
\begin{flushleft}
ᠣᠢᠷᠠ ᠵᠢᠨ ᠡᠳᠦᠷ᠂ ᠦᠪᠦᠷ ᠮᠣᠩᠭᠣᠯ ᠦᠨ ᠰᠢᠯᠢ ᠵᠢᠨ ᠭᠣᠣᠯ ᠠᠢᠮᠠᠭ ᠦᠨ ᠰᠢᠯᠣᠭᠣᠨ ᠬᠦᠬᠡ

ᠰᠢᠳᠬᠡᠭᠰᠡᠨ ᠪᠠᠢᠨᠠ᠃
\end{flushleft}
\stopmongolian
}
}
\end{document}
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.
Regards,
Jairo

Vertical typesetting (afaiks) involves two things: one character wide
columns and rotated glyphs. The first can be handled by the macro
package and the second by a combination of engine and macro package.
Already for quite a while there are the basics for a more advanced
vertical subsystem but it's typically one of these things that I explore
and then set aside till some users show up who need it and are willing
to spend time on discussing and testing intertfaces. After all, most of
this tex stuff is kind of a hobby and it's easy to find new interesting
experiments.
Anyway, you can get some ideas in chapter 6 of:
http://www.pragma-ade.com/general/manuals/followingup.pdf
but as said, probably no one ever read that. The question isnot so much
if it can be done, but how to integrate it.
(There's more stuff waiting for being used but we leave that for users
to run into and demand support for.)

[NTG-context] About vertical typesetting in ConTeXt
Hi list! I'm curious about vertical typesetting in ConTeXt. As far as I
know, LuaTeX supports four text directions, but LTL is broken for Manchu
script (letters are displayed unjoined in LTL mode) and LuaMetaTeX does not
support vertical directions anymore, at least as primitives.
I found the following solution:
https://tex.stackexchange.com/a/140972/193767
I reproduce the code (in XeLaTeX), just in case
% !TEX TS-program =
xelatex\documentclass{scrartcl}\usepackage{fontspec}\newfontfamily{\dcw}[]{DaicingWhite}%\begin{document}\noindent
Line above\\% to demonstrate that the lines are being stacked as

2 ᠮᠠᠨᠵᡠ ᡤᡳᠰᡠᠨ}% End font\end{minipage}\XeTeXupwardsmode0}% End rotatebox
\noindent
Line underneath\end{document}
and I see XeTeX uses the primitive \XeTeXupwardsmode and some other tricks
to get the proper display of Manchu text, so maybe MKII can do the magic
using XeTeX as an engine. How would one use ConTeXt MKIV for this task? Is
it possible to emulate \XeTeXupwardsmode in ConTeXt as a first step? Thank
