mkiv: Bug in Right to Left numerals?

mkiv: Bug in Right to Left numerals?

[Otared Kavian]

[-- Attachment #1: Type: text/plain, Size: 1382 bytes --]

Hi Hans, Taco, Idriss and the mkiv team,

Since I have been unable to use mkiv until very recently I am not  
aware whether the following bug has been addressed or not (Luigi  
Scarso taught me how to install and use mkiv on Mac OS, last Sunday…).

Below is a minimal file which shows that the numerals in Right-to-Left  
text are reversed, while they shouldn't.
XeTeX and XeConTeXt behave correctly in this respect.

If the bug is known, pardon me for the noise…
Best regards: OK

%% begin file bug-RL-numerals.tex
\starttext

\definefontfeature
[testPersian]
[analyze=yes,
mode=node,
language=dflt,
script=arab,
aalt=yes,
init=yes,
medi=yes,
fina=yes,
isol=yes,
liga=yes,
mset=yes]

\font\FaarsiA=arabtype*testPersian at 36pt

\startbuffer[faarsi]
این متن در سال ۲۰۰۸ مسیحی نوشته شده است.

\stopbuffer

(LuaTeX date stamp \luatexdatestamp).
\blank[6*big]
The number input as « 2008 » in Persian is written in the output as  
« 8002 » in the following Persian text:
\blank[6*big]
\pardir TRT
\textdir TRT

\FaarsiA
\getbuffer[faarsi]

This isn't actually a bug, \textdir TRT will reverse all text, try
setting \setupdirection[bidi=global] to enable the "experimental"
auto-bidi support.

Thanks Khaled for your attention, but what I get is:

! Undefined control sequence.
l.21 \setupdirection
                     [bidi=global]
?
Process aborted

Is this feature so experimental that it is not yet included in the  
latest beta?

Best regards: OK

\setupdirections[bidi=global]

Thanks Wolfgang… the plural makes sense indeed.
However it seems that it is necessary to add
\pardir TRT
\textdir TRT
before Right-to-Left text.
