Re: [NTG-context] Negative width vrule ignored in LuaMETATeX

Hi,
As I'm beginning to use ConTeXt LMTX, I experimented with it a little and
noticed some of my old documents different. After some examination I found the
following example:
\starttext

\stoptext
In LMTX, the result looks as if there is no `\vrule' between `a' and `b'. And if
I run with `context --engine=luatex', the expected result is back. I have
checked the luametatex manual but it doesn't seem to mention the difference. My
luametatex version is
mkiv lua stats > used engine: luametatex version: 2.0502,
functionality level: 20200413, format id: 493, compiler: clang.
Is the behaviour expected? Or shall I use other method to get non-discardable
negative space?
no, but i must admit that it's kind of a border case ... i'll fix it but
also wonder if *no* visual rule showing up is intended (i would then
also expect an engine to show a rule .. could be an interesting new
(luametatex) option as it saves kerns in some cases)

My use cases of negative vrule is a little tricky. I'm trying to comply with
W3C's [Requirements for Japanese Text Layout](https://www.w3.org/TR/jlreq/).
It states that
In principle, closing brackets (cl-02), commas (cl-07) or full stops (cl-06)
at the line end have a half em space after them (see Fig. 3.20). This half em
space can be deleted for line adjustment. However, the possibilities are only
half em space or solid. Other spaces, such as a quarter em space should not
be
used.
The tricky part is that I also want the opening fullwidth bracket at the
beginning of the line to be solid, i.e., without half em sidebearing on the left
to make the left margin visually more aligned (this is one but not the only way
of line begining handling shown in jlreq).
To achieve this, in the scripts handler I use the following injector between
'full_width_close' and 'full_width_open':
\hskip -0.5em \penalty 100 \hskip 0.5em minus 0.5em \vrule width
-0.5em height 0pt
^^^(a)^^^(b)
If line is broken here, the only broken points are (a) before the glue or (b) at
the penalty point. With the vrule the sidebearing of the opening bracket at
beginning of next line is eliminated.
In this particular case, a kern is not applicable because it won't survive the
line break. And here a vrule showing nothing is intended.
How about something ...
\startluacode
local classes = fonts.protrusions.classes
local vectors = fonts.protrusions.vectors
classes.myown = {
vector = 'myown',
factor = 1,
}
vectors.myown = table.merged (vectors.quality, {
[0x0028] = { 1, 0 }, -- (
[0x0029] = { 0, 1 }, -- )
})
\stopluacode
\starttext
\showframe
\definefontfeature[whatever][default][protrusion=myown]
\definedfont[Serif*whatever] \setupalign[hanging]
\dorecurse{100}{(#1) }
\stoptext
of course you need to define the cjk fences etc.

Re: [NTG-context] register entries in footnotes

This is a sentence with a term in the index: cat\index{cat}. This

footnote.\footnote{The footnote also contains an indexed term,

This creates two index entries for cat, which is not the intended result.
My questions are:
1. I would like to have the footnote number appear in the index, so it
says something like "cat 1 n. 1." Is that possible?
2. Is it necessary to define an extra command for index entries in
footnotes? Is context clever enough to know that it's processing a
footnote, so one could write a condition such as (pseudocode):
\define [1]
\myindex
{\infinfootnoteelse

(there are several mechanisms in context to deal with such issues, it's
all about getting specs from users i.e. tex is all about control so in

I am trying to typeset a two-column text in a right-to-left language
using ConTeXt. Because I want footnotes in this text to be set
ragged-bottom, I am using pagecolumns instead of standard columns. I
also want to track the first and last textual division markers on each
page using markings. Combining all of these ingredients seems to create
a problem in ConTeXt: when the pagecolumns are set in right-to-left
order, the top and bottom marks fetched are always the top and bottom
marks in the left column, while the true top mark should be the top mark
of the right column. I've observed this behavior using text in an actual
right-to-left language, but the following minimal (non-)working example
with an English sample text demonstrates the same behavior:
```
%Create a new markset to use:
\definemarking[TestMark]
%Setup header to reflect top and bottom marks:
\setupheadertexts[top: {\fetchmark[TestMark][top]}][bottom:
{\fetchmark[TestMark][bottom]}][top:
{\fetchmark[TestMark][top]}][bottom: {\fetchmark[TestMark][bottom]}]
%even left, even right, odd left, odd right
%Setup the columns layout:

\marking[TestMark]{7}(7) \input knuth\par
\marking[TestMark]{8}(8) \input knuth\par
\stoppagecolumns
\stoptext
```
I typeset this using ConTeXt version 2020.03.10, as released with
TeXLive 2020. As my comment in the MWE points out, there also seems to
be a bug in the key-value parsing of \definepagecolumns that causes it
not to parse the direction=reverse input unless it is followed by a comma.
Is there some way I can improve my syntax to avoid this issue, or is it
just a bug that needs to be fixed? I've tried fetching other marks
(e.g., first and last), but the only marks that ConTeXt seems to find
are the ones for the left column.

Hi list,
With 99% of work complete on a book, including single page images, I now
find myself confronted with a final problem: how to run one image across
facing pages or in other words, one image (plus its caption) across a
two-page spread, such that there is no gap.
I have tried a number of fairly crass attempts (obviously too simple) to
see if I could get somewhere near what I want, e.g.
\externalfigure[plate12.jpg][width=\paperwidth, height=.7\paperheight,
frame=none] {\tfx \sc Plates 12, 13. \tfx Twenty trucks from the
Netherlands setting off}
\externalfigure[plate13.jpg][width=\paperwidth, height=.7\paperheight,
frame=none] {\tfx for their first mission amongst the German diaspora.}
My thinking here was that \paperwidth might help extend the image to the
inner edge on the left-hand page, but it doesn't work that way for the
right-hand page, since there it extends to the outer edge, not the inner
edge! The .7\paperheight was to provide room for the caption. But all in
all, this is no solution!
If it is any help, the setup dimensions for the book are US Digest:
\definepapersize
[ACN][width=5.5in,height=8.5in] % w140mm x h216mm
I then looked up how one might do it in LaTeX, and found the following
link:
https://tex.stackexchange.com/questions/23860/how-to-include-a-picture-over-two-pages-left-part-on-left-side-right-on-right
How much of that would be transferable to ConTeXt? (I am thinking
particularly of the |\newcommand*{\twopagepicture}[4]| bit.
There are explanations for how to do this in InDesign, and since it is
something someone might often want to do (e.g. in magazines), I also
thought it might be easier to find reference to it on Contextgarden, yet
haven't found anything there. But I am sure ConTeXt has a way to do this.
Could someone point me in the right direction with this please?

The command line syntax has changed in version 1. See this:

So it's --export-filename in Inkscape 1.00, and --export-pdf in previous
versions.
If the conversion you need is done by
tex/texmf-context/scripts/context/ruby/graphics/inkscape.rb
you should edit that file and replace "--export-pdf" with
"--export-filename".
Thanks for this workaround but I suppose I'll need to edit that file
again after each context update…
However, the change in `inkscape.rb` has no effect, even after updating
the format with `context --make`… Any idea ?
Hi,
just wondering ... do you need that script when you use mkiv?

So a test of an environment variable instead of spawning a process to run "inkscape --version". hm, we can have for a while \enabledirectives[graphics.inkscape.oldversion] and use new as default (and of course you will wikify that, okay?)

mz = dofile("maze.lua")

Why does it happen? I guess it has something to do with math.randomseed,
but I don't know how to avoid this error message.
no, it's just lua running out of stack space so it depends on the binary
(and als the initial random value)
luatex 1.13 uses lua 5.3 which has a large stack but depending on the
compiler/linker settings and platform (it's 100 but depending on the
situatation you get a message or crash when that doesn't work out)
luajittex has a limited stack of 8000 so it will also crash
luametatex uses lua 5.4 which uses a bit different stack model and can't
go that high (it has a default of 2000 but i will bnump that to 6000
which still seems to work ok, that way i get upto a 120 maze)
(new lmtx upload later this weekend)

But why is it running out of stack? Isn't the walk function tail
recursive, in which case it should not cause a stack overflow
(https://www.lua.org/pil/6.3.html).
not really tail recursive: that is only true when it's the last action
and return is used and it nests very deep
function foo(...)

return foo(...)

versus
function foo(...)

if something then
foo(...)

Produces nice Optima at 14.9pt without \usemodule[article-basic] (as

some serif (modern?) font, /but only if I use nonstandard font sizes/.
Took me some time to hunt this one down.
I actually don’t know what article-basic does for me (I started out with
an example given to me by Hans) and I don’t need it now, but I might
need it later in combination with my own stuff

Re: [NTG-context] Placing number in \sqrt
On 5/4/2020 8:47 AM, cont...@vivaldi.net wrote:
Hello,
compare placing "3" in the following examples:
\starttext
$\sqrt[3]{5}$ % (1)
\par
$\sqrt[3~]{5}$ % (2)
\stoptext
In the first case, the "3" is placed naturally by ConTeXt and placed
more in the centre of "V" part of the square sign.
In the second example, the "3" is shifted manually by adding "~" and the
final placement seems to me a bit better.
What is your opinion - is the case (1) OK/intended and user should avoid
any manual shifting?
Or manual shifting is OK? Or is there a way to affect this placement
globally in ConTeXt, e.g. setting an internal variable?
The placement is driven by the font so kind of part of the design. There
is a whole bunch of parameters that drives placement and there is one
that deals with the spacing after the degree. Here are some examples.
\starttext
\def\R {\Umathradicaldegreeafter\textstyle0pt}
\def\RR{\Umathradicaldegreeafter\textstyle\dimexpr
\Umathradicaldegreeafter\textstyle+.1em\relax}
\def\RRR{\frozen\Umathradicaldegreeafter\textstyle\dimexpr
\Umathradicaldegreeafter\textstyle+.2em\relax}
$\sqrt[3]{5} \RR\sqrt[3]{5} \sqrt[3]{5} $\par
$\sqrt[3]{5} {\RRR\sqrt[3]{5}} \sqrt[3]{5} $\par
$ \RR\sqrt[3]{5} {\RRR\sqrt[3]{5}} \sqrt[3]{5} $\par
{\R $\sqrt[3]{5} \sqrt[3]{5} \sqrt[3]{5} $\par
{\RR $\sqrt[3]{5} \sqrt[3]{5} \sqrt[3]{5} $\par
{\RRR$\sqrt[3]{5} \sqrt[3]{5} \sqrt[3]{5} $\par
\stoptext
Changing these parameters inside math is kind of pseudo global: the
value at the end of the first pass is used for the whole formula.
However, in lmtx you can cheat by using the \frozen prefix to make it
behave local.
If we can come up with a proper name for a parameter we can make it a
setting. One of these things that Aditya and I will to discuss when we
have time and are in math mood. (There is much more in math we could
control if needed, but often in the end that control is not that much
needed at all.)

When I adapt the parameters that create parpath in my code, other uses
of lmt_followtext crash. The same combinations of text and path so far
haven’t crashed basic followtext().
I’ve run into comparable situations in my own code where I had to add
code to handle the existence of a (0,0) direction (e.g. when I had two
identical points on a path, but that is not the case here). The above
minimal example triggers the failure.
we can patch this
if ad <> origin : rotated(angle(ad)) fi
in mp-blob.mpiv but I expect you to test if all still works then

platforms ConTeXt supports; probably here:

But anyway - would it be possible to store the original value of HOME
environment variable (if set) before it gets changed during

- I would need to work with the original value in run-time (Win7 / WinX;

I'll add
environment.oldhome

[NTG-context] sunny friday afternoon update
Hi,
I uploaded a new version of lmtx and there are some experimental
features that users cna play with so that we can think about related
interfacing. (I won't mention soem in the lua department that I'm still
exploring myself.)
When you use a math symbol its class property determines the spacing.
One can use \mathopen etc to wrap such a character an dmake it behave
different. There is a new mechanism to overload that property in a
different way:
\startlines
$x\mathopen {!}+123+\mathclose {!}x$
$x\tomathopen ! +123+\tomathclose ! x$
$x\mathclose {!}+123+\mathopen {!}x$
$x\tomathclose ! +123+\tomathopen ! x$
$x ! +123+ ! x$
\stoplines
It uses a low level primitive, for the open case: \Umathclass 4 with the
number being the desired class.
A more experimental features concerns native prescripts. Consider the
following input
\blank \hbox{$
{\tf X}^1_2^^3__4 \quad
{\tf X}^1 ^^3\quad
{\tf X} _1 __4 \quad
{\tf X}^^3\quad
{\tf X} __4 \quad
{\tf X}^^3__4
$} \blank
or with the control sequence variants:
\blank \hbox{
\ruledhbox{${\tf X}\Usuperscript{a}
$}
\ruledhbox{${\tf X}\Usubscript{b}
$}
\ruledhbox{${\tf X}\Usuperscript{a}\Usubscript{b}
$}
\ruledhbox{${\tf X}\Usuperscript{a} \Usuperprescript{c}
$}
\ruledhbox{${\tf X}\Usubscript{b}
\Usubprescript{d}$}
\ruledhbox{${\tf
X}\Usuperscript{a}\Usubscript{b}\Usuperprescript{c}\Usubprescript{d}$}
\ruledhbox{${\tf X} \Usuperprescript{c}
$}
\ruledhbox{${\tf X}
\Usubprescript{d}$}
\ruledhbox{${\tf X}
\Usuperprescript{c}\Usubprescript{d}$}
}
\blank
A few days ago there was a discussion about tweaking some math
parameters, like the radical spacing. I made a macro that deals with it:
$\mathopenupparameter\Umathradicalvgap{10.5}\sqrt[3]{x}$
(this one is also in mkiv, be it slightly less efficient because in lmtx
we can use \Umathparameter to query the state of a variable)
Already present was a variant on \over which normally is used like
{{1}\over{2}}
i.e. the only time when tex looks back and needs to tweak styles. The
alternative is:
$\Uover{1}{2}$ etc
which looks forward but is otherwise compatible, apart from supporting
an optional keyword
$\Uover style \scriptscriptstyle{1}{2}$ etc
$\Uover style \textstyle{1}{2}$ etc
At some point I will adapt some context code to this.
Anyway, these are things that low level math users might like to play
with. There are few more things but those will probably go unnoticed.

Hi Hans,
Thanks for the quick fix of today's upload.
I could typeset your examples with \mathopen, \mathclose and these are great
features in order to fine tune the spacing in math mode.
Regarding the new command \Uover, I thought maybe it would be more consistent
to have the usual structure
${1} \Uover {2}$
like the more friendly ${1} \over {2}$ instead of having
That would involve backtracking and be a psin in the butt wrt control.
One can't have it all.
$\Uover{1}{2}$
which is more like the \frac structure.
Watch out: these are low level primitives (it is actually a set of
primitives that put stuff on top of each other). The \frac is the
interfaced variant.
Also a structure like
$\Uover style \textstyle{1}{2}$
seems a little bit far from the usual ConTeXt atmposphere… Would it not be
possible to have
${1} \Uover[style=textstyle] {2}$
instead?
That is what we have frac for (and one can define veriants that have set
styles).
In any case, thanks a lot for the constant addition of cute features…
Some of these engine level extensions have been on my list for a while
and eventually make implementing the user interfaced wrappers nicer (and
sometimes more robust). Some is actually possible because some engine
internals are a bit reorganized.

[NTG-context] new lmtx upload
Hi, The tex engine has at most 65K dimen and count registers and these can be local and global (although mixing these two models for the same variable can be inefficient). Anyway, in the current upload there is a mechanism for using way more variables, global ones, that are managed by lua: \luadimen test 100pt \scratchdimen = .25 \luadimen test \the\scratchdimen \the\luadimen test So, they act as normal dimensions and counters wrt assignment and serialization and such. There are also floats and booleans (in addition to integers and cardinals). Then, as another experiment, there are one/two dimensional arrays of variables. Think of: \newarray name whatever type integer nx 100 ny 500 \arrayvalue whatever 20 30 1024 \the\arrayvalue whatever 10 30 \the\arrayvalue whatever 20 30 \the\arrayvalue whatever 30 30 Some more info can be found in the last chapoter of the evenmore.pdf document. The question is: do we need this, and if so, do we need more of that. It's a bit chicken-egg case: we can have lua and can pipe back to tex, and we can stay at the tex end. This is a lmtx only feature. Just for the record: these are macros, not primitives, but they are rather efficient and have hardly any overhead. The floats can be in 1.23 format, 1.23e45 format and also in 0x12p34 format, while integers can be in 123 format and 0x123 format; the hex float format is lua's way of being roundtrip. Hopefully there are no side effects.

/Span /paragraph /P /section /Sect /sectioncaption /Div /sectioncontent
/Div /sectionnumber /H /sectiontitle /H >> /Type /StructTreeRoot >>

and the tag `mycommand` is used at appropriate location.
However, the exported xml file contains no tag:
```

What am I missing in order to pass user-defined macros to the exporter?
you're probably missing documentation + a high level define command
This registers (extra) elements:

OK. I just noticed in lmtx documentation that \paperheight and

what rteplaces them. So, all the documentation that contains them has
been invalidated (e.g. examples in details.pdf)
I can't find \pagewidth in the current versison of details.pdf.
As Pablo wrote you can use \paperwidth (or \printpaperwidth) or one of
the following methods.
begin example
\setupexternalfigures[location=default]
\setuplayout[tight]
\showframe
\starttext
\centerbox{\externalfigure[mill.png][width=\textwidth]}
\page
\centerbox{\externalfigure[mill.png][width=\paperwidth]}
\page
\centerbox{\externalfigure[mill.png][factor=max]}
\page
\centerbox{\externalfigure[mill.png][factor=min]}
\stoptext
end example
\pagewidth etc were low level engine primitives that were never meant to
be used directly (backend related, and even then very sensitive for
confusion); as Wolfgang indicated, these were never supposed to be used
directly

Which file is closed here? Experiments with a custom format suggest that the
read
files are opened through the `open_data_file` callback, so even if they
are closed they probably should be closed by calling the `.close` member
of the returned table. But that never happens (This might be a related
bug: In my experiments, even for files loaded with `\input`, the close
function is never called.) and the issue seems to occur even if there is
no real file opened for this. So I don't see why LuaMetaTeX should call
fclose here at all. But anyway, thanks for looking into this.
end_file_reading is always called but has to close selectively,
dependent on what has been opened, eep in mind that a token list or so
is also an input stream

Hi,
`context --purgeall filename` behaves differently from `context

`context --purgeall` deletes all files with the name `*-temp-*`. I
would have thought that `context --purgeall filename` will delete all
files with the name `\jobname-temp-*` but it does not.
Is there a way to delete the `\jobname-temp-*` files without requiring
an extra `context --purgeall` run? This is needed for deleting extra
files by `t-filter` module or deleting extra files generated by
automatic EPS to PDF conversion (with
figures.cachepaths.prefix="\jobname-temp"), etc.
As an aside, I also noticed that in both mkiv and lmtx, mtx-context.lua has
local extra_runfiles = {
"^l_m_t_x_.-%.pdf$",
}
but graph-inc.lua has
local defaultprefix = "m_k_i_v_"
So, the default generated files are never deleted.
i can add it ... originally that was for the temporary pdf jobname i think

Re: [NTG-context] About Latex compatibility module

Hi everyone! I was reading some old posts on TeX.SX about LaTeX support
on ConTeXt and I found the following:
https://web.archive.org/web/20110822085249/https://modules.contextgarden.net/LaTeX
However, not only the module seems to be deprecated, but there's no more
info about the module now (links are broken and the like). Btw the test
file (latextest.tex) included fails to compile:
> tex error on line 165 in file t-ltmsen.tex: ! Undefined control sequence
>> \newskip\@rightskip \@rightskip \z@skip
looks like someplace one has to define \z@skip to be 0pt (in this case
it's actually redundant code because a newskip is likely to be zero)
Is it possible to make it work? I think it would be nice if some minimal
LaTeX macros were supported. Thank you in advance!
Depends. It's not that hard to define some basic 'handle some latex
cases' module but the question is "for what purpose?". When I look at
those decade old files in that archive I see a lot of messy code that
one needs to isolate and even then we can assume that users use more
than a few commands. When they only use the top-ten commands, no
problem, but when they start setting lengths or so ... why use context
then. I have no problem mapping a few commands so that new users can
cut-n-paste some code as a starter but somehoen has to come up with the
list of commands and minimal test files then.
Apart from the (probably a bit boring) challenge I think it doesn't pay
off. Also, the systems are conceptually too different I think.

Re: [NTG-context] \setupbackend in MkIV

I cannot get a PDF/A document produced with the latest MkIV beta

Removing either of the \setupbackend instructions still results in the
same error.
Same issue for PDF/X.
Is it a bug, or is it me?
It's a bug, there is a check in the MkIV version of the code which
should be only in the LMTX version.
I uploaded new versions.
We're also redoing some low level support macros; these were (and have
been) okay so there is no real need to replace them but by using some
new features they could be done a bit nicer and they even became a bit
faster cq. have less imprint on memory usage, but that will only be
noticed in extreme documents that rely on them, like maybe thomas 1000
page natural tables or Massi's configuration extensive applications;
we'll see.
Wolfgang and I are checking these modules and related core code which
will take a while (the test suite runs ok) but any issues, if any, will
be solved fast. In due time it might bring some additional options.

Anyway, what you need to do it this:
\number\fontid\font
which will work in mkiv and lmtx or
\the\fontid\font
which also works in lmtx.
I changed a couple of these 'internal quantities' to behave like number
tokens which has some advantages (for instance, such a token doesn't
need to have a space or \relax as sentinel in situations where a
lookahead can spoil your game). There is a whole bunch of these
quantities and some were numbers and some serialized numbers and i just
made that consistent across the repertoire. It's anyway good practice to
put something \number in front when you wonder of what you get is a
number. Just consider it progress.
(there's also \setfontid so maybe you don't need the lua code at all)

No such problems with integer rotation numbers.
ConTeXt expects a integer for the rotation value and decimals are only

I think this may be a bug, since the sample above would only get "yes"

No spaces are allowed in these lists. Older versions of the command
removed the spaces before the entries but the current version is stricter.
we can use the old one, so only the raw variants then ignore the space;
best to be downward compatible, even if this was never the formal spec
(more a side effect)
it's only 20% slower and internally we we often use the raw one

A lot is possible. Take this:
\def\MyMacroA{Ahoj A}
\unexpanded\def\MyMacroB{Ahoj B}
\frozen\def\MyMacroC{Ahoj C} % in lmtx
% \def\MyMacroC{Ahoj C} % barks
At the tex end you can check for several properties:
\ifusercmd \hbox Y\else N\fi % in lmtx
\iffrozen \hbox Y\else N\fi % in lmtx
\ifusercmd \MyMacroA Y\else N\fi % in lmtx
\iffrozen \MyMacroA Y\else N\fi % in lmtx
\iffrozen \MyMacroC Y\else N\fi % in lmtx
At the Lua end you can check for being defined:
\startluacode
local function whatever(s)
context.type("\\" .. s)
context(" is %s", tokens.defined(s) and "defined" or "undefined")
context.par()
end
whatever("MyMacroA")
whatever("MyMacroD")
whatever(" ")
whatever("-")
\stopluacode
alternatively you can say:
\startluacode
local t = token.create("MyMacro")
print(t.cmdname == "undefined_cs")
\stopluacode
which is less efficient unless you want to access more properties.

Because the macro actually *is* defined: as soon as tex sees
\foo
it reserves the name and gives it the meaning undefined, so even
\undefined is defined.
Anyway, that is why we have \ifdefined that does a different kind of
checking. In retrospect, that is a better one, so I'll adapt that in lmtx.

You can do this in current luatex/mkiv:
if CONTEXTLMTXMODE == 0 then
local d = tokens.defined
local c = tokens.create
function tokens.defined(s,b)
if b then
return d(s)
else
return c(s).cmd_name == "undefined_cmd"
end
end

It depends on the version and engine. For luatex we also depends on the
interfacing that the texlive ecosystem provides. As Akira mentions,
there have been some developments in that area but I didn't test that
yet (no files with utf names here) but I trust his (always done) testing
of context. That will trickle into future binaries (which is somewhat
tricky as we have experimental as well as current).
In luametatex things are different. There all windows specific
operations have wide-character support, that is, the utf8 goes via utf16
and codepages and such: filenames, environment variables, command line
arguments, whatever.
That said: I never use non-ascii non-spacy names ... it's the most
portable.

OK, thanks. No hurry. The production projects run on some oldish
2019 MkIVs anyway. I'm trying to get my feet wet with lmtx and run
it on some projects to check how usable and compatible it is.
It should be compatible, although at some point there will be
functionality that is only in lmtx. Okay, metapost is an exception,
because there is a lot in lmtx that is not in mkiv, but that's a
separate subsystem anyway.

Re: [NTG-context] About vertical typesetting in ConTeXt
On 6/10/2020 7:49 AM, Jairo A. del Rio wrote:
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}\noindentLine
above\\% to demonstrate that the lines are being stacked as
normal\rotatebox{-90}{%\XeTeXupwardsmode1\\% successive lines will be
stacked upwards instead of downwards\begin{minipage}{4em}% this will be
the vertical length of the Mongolian section{\dcw% Font: Daicing White1
ᠮᠠᠨᠵᡠ ᡤᡳᠰᡠᠨ\\% direct Unicode input of Manchu letters2 ᠮᠠᠨᠵᡠ ᡤᡳᠰᡠᠨ }%
End font\end{minipage}\XeTeXupwardsmode0 }% End rotatebox\noindentLine
underneath \end{document}|
and I see XeTeX uses the primitive |\XeTeXupwardsmodeand 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 you very much.
I admit that I have no clue about what xetex does in that departmentbut
you're right that in lmtx the vertical directions are not supported. The
main reason is that it didn't really integrates well in the way pages
are constructed.
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.)
