Using the three bidi methods of \setupdirections[bidi]:

let's first try to get that one right .. new beta coming (also needs 
testing by idris



- ‘one’ does not render either the note block nor the individual notes' texts 
right-to-left.


i have to rewrite that one using more efficient means (i really need 48 
hour sin a day)



- ‘two’ is identical to method ‘one’.


it is .. just a newer version of the unicode bidi one


Compare these to regular footnotes, where everything is rendered correctly as 
of this new beta.


you can trace flagging in default with:

Re: [NTG-context] r2l alignment and linenumbering conflict?

[Otared Kavian]

Hi Hans,

Thanks for the new beta.

As Idris pointed out, the logic you follow for naming greeknumerals, 
romannumerals, persiannumerals, arabicnumerals, and all others in core-con.lua, 
makes sense but I didn’t notice this logic before…  Which means one may learn 
each and evry day :-)

As far as I know, at least in the Persian use of the abjad system of counting, 
the first case corresponding to the number 1, is usually written 
الف
in order to avoid the confusion with the digit 
۱

I don’t know if this can be fixed in the table you have in core-con.lua.

A further remark is that, don’t you think that the pagenumbering, as well as 
the numbers for chapters, sections, items, equations, etc, should be switched 
by default to arabicdecimals, or persiandecimals, as soon as \mainlanguage has 
been set to arabic or persian?
Or maybe one could have a command like
\setupdefaultnumberings[arabicdecimals]
which sets a default for conversion of numbers for all the counters.

Again many thanks for the features you included in ConTeXt for bidi writing.

Best regards: OK

Re: [NTG-context] r2l alignment and linenumbering conflict?

[tala...@fastmail.fm]

Hans, the beta is a solid step forward regarding bidi and Arabic support, and 
not just in footnotes. Thank you.

However, it appears that my earlier declarations of ‘problem solved’ were a bit 
premature.  Footnotes display everything correctly, but not linenumber notes. 
Using the three bidi methods of \setupdirections[bidi]:

- ‘default’ orders the linenumber notes and their texts right-to-left, but any 
number therein is reversed (4102 instead of 2014).

- ‘one’ does not render either the note block nor the individual notes' texts 
right-to-left.

- ‘two’ is identical to method ‘one’.

Compare these to regular footnotes, where everything is rendered correctly as 
of this new beta.

Below is a minimal example with resulting PDF output.

so you and idris and tatal has to come to some agreement on that

we have these alphabetic ones

arabicnumerals
persiannumerals
arabicexnumerals

and some special ones

abjadnumerals
abjadnodotnumerals

(these use small, medium, large chars and do special things with 10 100

and now

arabicdecimals
persiandecimals

Hi Hans, Idris, Talal,

Some years ago we had a discussion on the issue, but I don’t remember where we

Re: [NTG-context] r2l alignment and linenumbering conflict?

[tala...@fastmail.fm]

Well, I don’t know if ‘solves’ the underlying questions that Hans wrote about, 
but after some more fiddling, I now have all the numbers appearing as I expect 
them to.

It required specifying `method=two` as part of 
`\setupdirections[bidi=global,method=two]`. That, along with the 
`numbercommand=\righttoleft` in \setuphead[section], means that it now looks as 
I expect it to.

Unless someone identifies a problem with any of this, I think I’ll write up a 
summary on the Wiki. Without trolling through the mailing list for anything on 
RTL and then experimenting with the various combinations, it would be hard for 
one to divine how to get this to work.

Re: [NTG-context] r2l alignment and linenumbering conflict?

[tala...@fastmail.fm]

Just to note: all numbers in the body text are having their digits placed 
individually right-to-left. Notice, in the attached PDF, how the ١٤ is 
displayed as ٤١, and how ١٨٧٢ is ٢٧٨١ … but also the footnote marker is ٣١ 
instead of ١٣ as it correctly is below in the footnote itself.

Is there any temporary work around for this, until we sort out the underlying 
causes?

What's wrong with 'persiannumerals' and 'arabicnumerals' which we had

any case we need

U+: [0030-0039] -> [0660-0669]: arabicdecimals
U+: [0030-0039] -> [06F0-06F9]: persiandecimals


don't confuse decimals with alphabetic ones

a b c ... z aa ab ac ... az 

vs

1 2 3 ... 10 11 12

so decimals is mapping chars 0-9 onto whatever else, in principle we can  
have 15 => ae and 21 => ba


Sure, but that's what abjadnumerals are for. Right now we have

abjadnumerals=persiannumerals=arabicnumerals

If that's intentional, then no problem, arabicdecimals and persiandecimals  
are fine nomenclature


Ah, it just hit me: You're making a literal analogy with romannumerals

Just a reminder (and of course unicodedata.txt has this info):  
persiandecimals behave *exactly* as latindecimals, while arabicdecimals  
have a "weak" bidi property.

we have several approaches:

the oldest method is based on some heuristics and targets at tex input

the other two are unicode bidi based (successive versions and there 
might be more as that evolves)


in any case, everything bidi / rl has to fit into some system and that's

Re: [NTG-context] r2l alignment and linenumbering conflict?

[tala...@fastmail.fm]

I am having problems with the directionality of numbers and mirrored characters (like parentheses). When using bidi, the numbers are inverted (5102 instead of 2015); with the explicit commands, the mirrored characters are inverted as well.For reasons I think I understand, this is only happening in the text: the problem occurs with numbers in headings (chapters, etc.), and likewise in the main of the text. The digits of footnotes, linemargin numbers, and page numbers are correctly arranged.I have learnt that if I add the option [numbercommand=\lefttoright] to \setuphead[section], I can get the digits in the section number to be in the right order. But this does not address the problem of other numbers in the text.How do I solve this? I am happy to abandon the conveniences of bidi, as Idris suggests might be needed (see below), but it didn’t get any easier when trying to do it manually. See MWE below.With thanks,Talalp.s. The Wiki page on "Arabic and Hebrew" is out of date, instructing the use of \setcharactermirroring[1] which is clearly deprecated now in favour of \setupdirections[bidi=global]. I am happy to update the wiki page once I get my head around things. Does anybody have an authoritative list of the various commands related to right-to-left, as well as what combinations are not needed (e.g. are \setupalign[r2l] and \righttoleft overlapping, or do they play different roles)?%%% LANGUAGE AND FONTS\mainlanguage[arabic]	\definefontfamily [mainface] [rm] [ALM Fixed][range=arabic,features=arabic]	   \setupbodyfont[mainface,12pt]%\setupdirections[bidi=global]\setupalign[r2l]%\righttoleft%% HEADINGS\setuphead[chapter,section][	conversion=myconversion,%	numbercommand=\lefttoright % <-- toggle	]\setuplinenumbering[conversion=myconversion]\setupnotations[footnote][numberconversion=myconversion]\setupnotations[linenote][numberconversion=myconversion]\setuppagenumber[numberconversion=myconversion]\defineconversion	[myconversion]	[١,٢,٣,٤,٥,٦,٧,٨,٩,١٠,	١١,١٢,١٣,١٤,١٥,١٦,١٧,١٨,١٩,٢٠,	۲۱,۲۲,۲۳,۲٤,۲٥,۲٦,۲۷,۲۸,۲۹,۳۰,	٣١,٣٢,٣٣,٣٤,٣٥,٣٦,٣٧,٣٨,٣٩,٤٠,	٤١,٤٢,٤٣,٤٤,٤٥,٤٦,٤٧,٤٨,٤٩,٥٠,	٥١,٥٢,٥٣,٥٤,٥٥,٥٦,٥٧,٥٨,٥٩,٦٠,	٦١,٦٢,٦٣,٦٤,٦٥,٦٦,٦٧,٦٨,٦٩,٧٠,	٧١,٧٢,٧٣,٧٤,٧٥,٧٦,٧٧,٧٨,٧٩,٨٠,	٨١,٨٢,٨٣,٨٤,٨٥,٨٦,٨٧,٨٨,٨٩,٩٠,	٩١,٩٢,٩٣,٩٤,٩٥,٩٦,٩٧,٩٨,٩٩,١٠٠,	١٠١,١٠٢,١٠٣,١٠٤,١٠٥,١٠٦,١٠٧,١٠٨,١٠٩,١١٠,	١١١,١١٢,١١٣,١١٤,١١٥,١١٦,١١٧,١١٨,١١٩,١٢٠,	١٢١,١٢٢,١٢٣,١٢٤,١٢٥,١٢٦,١٢٧,١٢٨,١٢٩,١٣٠,	١٣١,١٣٢,١٣٣,١٣٤,١٣٥,١٣٦,١٣٧,١٣٨,١٣٩,١١٣٠,	١٤١,١٤٢,١٤٣,١٤٤,١٤٥,١٤٦,١٤٧,١٤٨,١٤٩,١٥٠,	١٥١,١٥٢,١٥٣,١٥٤,١٥٥,١٥٦,١٥٧,١٥٨,١٥٩,١٦٠,	١٦١,١٦٢,١٦٣,١٦٤,١٦٥,١٦٦,١٦٧,١٦٨,١٦٩,١٧٠,	١٧١,١٧٢,١٧٣,١٧٤,١٧٥,١٧٦,١٧٧,١٧٨,١٧٩,١٨٠,	١٨١,١٨٢,١٨٣,١٨٤,١٨٥,١٨٦,١٨٧,١٨٨,١٨٩,١٩٠,	١٩١,١٩٢,١٩٣,١٩٤,١٩٥,١٩٦,١٩٧,١٩٨,١٩٩,٢٠٠,	٢٠١,٢٠٢,٢٠٣,٢٠٤,٢٠٥,٢٠٦,٢٠٧,٢٠٨,٢٠٩,٢١٠,	٢١١,٢١٢,٢١٣,٢١٤,٢١٥,٢١٦,٢١٧,٢١٨,٢١٩,٢٢٠,	٢٢١,٢٢٢,٢٢٣,٢٢٤,٢٢٥,٢٢٦,٢٢٧,٢٢٨,٢٢٩,٢٣٠,	٢٣١,٢٣٢,٢٣٣,٢٣٤,٢٣٥,٢٣٦,٢٣٧,٢٣٨,٢٣٩,٢٢٣٠,	٢٤١,٢٤٢,٢٤٣,٢٤٤,٢٤٥,٢٤٦,٢٤٧,٢٤٨,٢٤٩,٢٥٠,	٢٥١,٢٥٢,٢٥٣,٢٥٤,٢٥٥,٢٥٦,٢٥٧,٢٥٨,٢٥٩,٢٦٠,	٢٦١,٢٦٢,٢٦٣,٢٦٤,٢٦٥,٢٦٦,٢٦٧,٢٦٨,٢٦٩,٢٧٠,	٢٧١,٢٧٢,٢٧٣,٢٧٤,٢٧٥,٢٧٦,٢٧٧,٢٧٨,٢٧٩,٢٨٠,	٢٨١,٢٨٢,٢٨٣,٢٨٤,٢٨٥,٢٨٦,٢٨٧,٢٨٨,٢٨٩,٢٩٠,	٢٩١,٢٩٢,٢٩٣,٢٩٤,٢٩٥,٢٩٦,٢٩٧,٢٩٨,٢٩٩,٣٠٠,]%%% DOCUMENT\starttext \showframe \section{section one}\startlinenumbering\input tufte\input tufte\stoplinenumbering\dorecurse{20}{\section{محمد الجمل (١٨٧٢—١٩٢٣)}	مرحباً باعالم . ١٢٣٤٥٦٧٨٩٠ مرحباً بالعالم. ولد عام١٩٣٤.\footnote{تعليقة لطيفة.}\pagebreak}\stoptext=

Re: [NTG-context] r2l alignment and linenumbering conflict?

[tala...@fastmail.fm]

Thank you very much for this, Idris. What with the other bugs and problems I’ve 
faced with R2L (in footnotes, etc.), I was starting to wonder whether a more 
explicit, rather than global, use of RTL might be a better approach. I’m going 
to experiment with them, at least to learn how to use them with greater focus.

The good news is that apparently Hans has already patched the page-lin.lua file 
that Wolfgang had identified as the culprit, and it will be included in the 
next beta. 

Many thanks to you, Pablo, Wolfgang, and of course Hans so much for your help 
in getting these right-to-left issues solved. There are a couple of small bidi 
issues remaining, including that mentioned in the “footnotes when using RtL 
(Arabic)” thread. The one or two other ones I will post shortly. But, in any 
case, I have now completely moved my project over into ConTeXt, confident that 
it (and the team behind it) can handle all of the needs of a multilingual 
academic monograph and of a bi-direction, Arabic critical edition’s need

With many thanks,
Talal

You're right. \thinrule has LR unicode characters which is probably why it

with either global RL or 2) invoke RL inside the linenumbering it will  
work:


% \setupdirections[bidi=global]
\righttoleft %% global RL

or just

\startlinenumbering
\righttoleft %% local RL, not needed if global RL invoked
\startalignment[r2l]

Again, it's a barbarous (and temporary) workaround. See attached.

I'm not at all suggesting that this particular bug should not be a  
priority; printing paragraph lines in a linenumbering environment *must*  
be direction-agnostic. Just a matter of general strategy to consider.

Talal, here is a barbarous workaround using \thinrule:

==
\setuppapersize[A6]
\starttext \showframe

\setupthinrules[color=white]
\setupwhitespace[big]

\section{Incorrect}
\startlinenumbering
\startalignment[r2l]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.\thinrule


Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.

\stopalignment
\stoplinenumbering

\section{Correct}
\startalignment[r2l]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque  
molestie dictum quam non congue. Integer ut dolor vel mi vestibulum  
molestie vel et nulla.

\stopalignment

\stoptext
==

This effectively hides the problem. Unfortunately it is apparently not  
straightforward to invoke the \thinrule automatically at the end of every  
paragraph [see the other thread with Alan].

Thanks for that, Wolfgang. I can only hope that, as the culprit is known, it 
can be apprehended!

Sorry to pester, but this problem is barring me from moving my book 
project into ConTeXt this weekend.


The use of linenumbers seems to throw off the R2L mechanism. Example 
of the problem attached.




The culprit is the function "boxed.stage_two" in page.lua which output 
each text line in the line numbering
environment in left to right mode. When you have justified lines 
everything is fine but when you have a ragged
line (e.g. the last line in a paragraph) ConTeXt aligns the context with 
the left margin.


\starttext \showframe

\startalignment[righttoleft,flushleft]

\input ward

\blank

\startlinenumbering
\input ward
\stoplinenumbering

\stopalignment

\stoptext

Re: [NTG-context] r2l alignment and linenumbering conflict?

[Idris Samawi Hamid ادريس سماوي حامد]

Dear Talal,
Salaam.

Your tex file linertl.tex appears to be corrupted, could you either repost  
it or send it to me off list?


I was also going to write something similar to Pablo. My suggestion is to  
move forward with the rest of your project and this will almost certainly  
be solved before you're done. Unless Hans says that there is no chance of  
a fix, which I *highly* doubt. Send a reminder to the list every few days  
or so, as you did today.


Proceeding this way produces an uneasy feeling; believe me, I know. But  
I've been in your shoes more times than I can count and it always worked  
out in the end.


Best wishes
Idris

The RTL alignment works correctly on its own. However, when you  
introduce another factor — here,  linenumbers — the RTL alignment is  
ignored.


Perhaps this linked to the problem with of RTL footnotes being  
discussed here: gmane.comp.tex.context/92113  
?

Talal

Hi Talal,

I’m afraid that I don’t have a fix for what it might be a bug in ConTeXt.

If you want to work on you book before a fix is released, I’d suggest
you to add the following line at the top of your document:

\definestartstop[linenumbering]

This will deactivate line numbering and it will allow you to work on the
rest of the book without having to add any code later.

If your book is already finished, you only have to wait for the fix ;-).

Just in case it helps,


Pablo
