RTL section heads
Hi, This is concerning an RTL text. I have one chapter and 10 sections under that. My goal is to achieve the following. 1) The number 10 should appear correctly with '1' visually to the left of '0'. 2) The chapter number should visually appear to the right of the section number. 3) Chapter and section numbers should be separated with a dash. (This is ignored in this email and I will follow up about it in another thread. To get a minimal working example, I also do not try to change the numbers to use Persian digits.) In particular, the headings will be visually something like the following (aligned to the right). elpmas 1 txet 1-1 txet 2-1 txet 3-1 ... txet 10-1 Here's the first attempt. %% Attempt 1 \setupalign[r2l] \starttext \placecontent \chapter{sample} \dorecurse{10}{\section{text}} \stoptext The result is: elpmas 1 txet 1-1 ... txet 01-1 Then I add "\setupdirections[bidi=global,method=default]" to the beginning and I get the most strange result (number right-aligned but texts left-aligned): sample 1 text 1.1 ... text 1.10 A third attempt gives almost what I want (without period as the separator). %% Attempt 3 \setupalign[r2l] \def\LTR#1{{\lefttoright#1}} \def\leftnumbers#1{\LTR{\numbers{#1}}} \defineconversion[leftnumbers][\leftnumbers] \setuphead[chapter,title,section,subject] [conversion=leftnumbers] \starttext \placecontent \chapter{sample} \dorecurse{10}{\section{text}} \stoptext The big problem is that in my RTL documents, I always have the setupdirections command, which messes things up here. (This makes it difficult to one section name with English title, which should still be typeset on the right-hand side of the page.) Note that in attempt 2 above, there were two issues: (1) Text and numbers appeared on the two far ends of the screen instead of being close to each other. This does not happen when I use Farsi text. (2) Chapter number appears to the left of section number. %% Attempt 5 \usemodule[simplefonts] \setmainfont[ALM Fixed][features=arabic,range=arabic] \setupdirections[bidi=global,method=default] \setupalign[r2l] \starttext \placecontent \chapter{نمونه} \dorecurse{10}{\section{متن}} \stoptext Interestingly the table of contents looks fine if I put the number inside an LTR macro; still in the main body, the section heads are typeset incorrectly. %% Attempt 6 \usemodule[simplefonts] \setmainfont[ALM Fixed][features=arabic,range=arabic] \setupdirections[bidi=global,method=default] \setupalign[r2l] \def\LTR#1{{\lefttoright#1}} \def\leftnumbers#1{\LTR{\numbers{#1}}} \defineconversion[leftnumbers][\leftnumbers] \setuphead[chapter,title,section,subject] [conversion=leftnumbers] \starttext \placecontent \chapter{نمونه} \dorecurse{10}{\section{متن}} \stoptext I guess the solution is to get the entire section head number string (e.g., 1.10) to have RTL direction, however, each individual number string inside (say, 1 or 10) should be written LTR. How can this be achieved? The six TeX files (with corresponding PDF outputs) are attached. BTW this is using ConTeXt ver: 2016.04.01 13:01 MKIV beta fmt: 2016.4.7 int: english/english, running LuaTeX, Version beta-0.90.0 (TeX Live 2016) on Mac OS X. Thanks a lot, —MHB
Hans & Wolfgang,
Do you have suggestions here? How can I get the behavior I want for the
section head numbers?
In fact, the following may be quite relevant.
\usemodule[simplefonts]
\setmainfont[ALM Fixed][features=arabic,range=arabic]
\setupdirections[bidi=global,method=default]
\setupalign[r2l]
\starttext
اعداد ۱، ۲، ۳ و ۴ را در نظر بگیرید.
اعداد 1، 2، 3 و 4 را در نظر بگیرید.
اعداد 1, 2, 3 و 4 را در نظر بگیرید.
\stoptext
I expect the numbers 1, 2, 3 and 4 to appear in the same order from right
to left. However, the visual order that I observe (regardless of whether I
use Persian digits or English digits, or whether I use Persian or English
commas) is 4, 1, 2, 3 (from left to right). Is this a bug in the bidi
code? If so, are there any workarounds?
Thanks,
Hossein

Thanks, Hans! This does solve the problem with the list of numbers. And
actually if I add a numberstyle field, I can the section heads the way I
like. Here is the setup that worked. (I will update Wiki later.)
\setupdirections[bidi=global,method=two]
\setupalign[r2l]
\def\LTR#1{{\lefttoright#1}}
\def\leftpersiandecimals#1{\LTR{\persiandecimals{#1}}}
\defineconversion[leftpersiandecimals][\leftpersiandecimals]
\setuphead[chapter,title,section,subject]
[conversion=leftpersiandecimals,numberstyle=\righttoleft]
\defineseparatorset[dashsep][-,-,-,-]
\setuphead[section][sectionseparatorset=dashsep]

Unfortunately when I use method=two for bidi, the numbers in the main body
are written from right to left. I'm starting to wonder whether it does
anything nontrivial at all.
\usemodule[simplefonts]
\setmainfont[ALM Fixed][features=arabic,range=arabic]
\setupdirections[bidi=global,method=two]
\setupalign[r2l]
\starttext

I'm pretty sure this used to work (for example in version 2016.01.18
22:21). A similar piece of code is working fine on the website
http://wiki.contextgarden.net/RTL. I'm using CONTEXT version: 2016.04.01
13:01. I also verified that it is not working in version: 2016.04.10 23:52.

Hi Hans and Mohammad Reza, I can confirm that the wrong behaviour of numbers and digits in Right to Left (more specifically Persian) is recent: indeed with ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 2015.6.18 int: english/english from TeXLive 2015 the numbers and digits are rendered as they should. Is it related to some changes in LuaTeX? Best regards: OK
