Can't use with Arabic text (packages)

ktobah commented 7 years ago

Dear,

I am trying to write a journal paper in English that includes some Arabic text. However, the compilations fail every time. I tried the arabtext and arabxetex packages with pdflatex, xelatex, and lualatex, but nothing works.

Can you please assist me with this? Thank you

borisveytsman commented 7 years ago

could you post a minimal example?

ktobah commented 7 years ago

Sure.

\documentclass{acmart} %if the class is {report} it works fine

\usepackage{arabtex}
\usepackage[utf8]{inputenc}
\usepackage[LFE,LAE]{fontenc}
\usepackage[arabic]{babel}

يعود تاريخ علوم الحاسوب إلى اختراع أول حاسوب رقمي حديث. فقبل العشرينات من القرن العشرين، كان مصطلح حاسوب \textLR{Computer} يشير إلى أي أداة بشرية تقوم بعملية الحسابات. ما هي القضايا أو الأشياء التي يمكن لآلة أن تحسبها باتباع قائمة من التعليمات مع ورقة وقلم، دون تحديد للزمن اللازم ودون أي مهارات أو بصيرة (ذكاء)؟ وكان أحد دوافع هذه الدراسات هو تطوير آلات حاسبة \textLR{computing machines} يمكنها إتمام الأعمال الروتينية والعرضة للخطأ البشري عند إجراء حسابات بشرية.
خلال الأربعينات، مع تطوير آلات حاسبة أكثر قوة وقدرة حسابية، تتطور مصطلح حاسوب ليشير إلى الآلات بدلا من الأشخاص الذين يقومون بالحسابات. وأصبح من الواضح أن الحواسيب يمكنها أن تقوم بأكثر من مجرد عمليات حسابية وبالتالي انتقلوا لدراسة تحسيب أو التحسيب بشكل عام. بدأت المعلوماتية وعلوم الحاسب تأخذ استقلالها كفرع أكاديمي مستقل في الستينات، مع إيجاد أوائل أقسام علوم الحاسب في الجامعات وبدأت الجامعات تعطي إجازات في هذه العلوم .

If you just keep hitting in the console, your example finishes OK for me. But I don’t read arabic, so cannot tell if it really is correct.

The processing problem occurs with internal coding from the MicroType package, which is loaded by the ACM classes. That is, \MT@res@a is used internally within microtype.sty .

So the question could well be “does it make sense to use micro type with arabic input?’'

If not, then how can it be cleanly disabled when it occurs, e.g. within a \begin{otherlanguage} environment? Is there is similar problem with other foreign (i.e., non-english) languages, in particular those using non-latin-based scripts?

So, should the disabling mechanism be tied to all uses of otherlanguage , or just to arabic, and other non-latin scripts?

Dear Dr Moore,

Thank you for your reply. It is helpful. But as I mentioned I am using the Overleaf Online editor, so I don't have access to the console.

I hope the developer will shed some light on this. I am not so familiar with how the commands of Latex works (the programming side of things), so I really can't help.

Hi Tobias,

I now think microtype is a red herring. The problem is a bit more severe, with MT just happening to correspond to where unwanted expansions become completely intractable.

I’ve looked at this in more detail now, with tracing. It’s not occurring within the arabic text, but at the end of this document, while writing the page-number into the .aux file, via the 2nd argumant in \newlabel{TotPages}{…} .

The \thepage macro is necessarily not robust, so expands including a font-setting command \latintext . This creates a mess in the .aux file, as well as subsequent expansion errors.

viz. \newlabel{TotPages}{{1}{\protect \protect \bgroup \beginL \protect \protect \edef LAE{T1}\let \enc@update \relax \protect \xdef \T1/LinuxLibertineT-TLF/m/n/9 {\LAE/LinuxLibertineT-TLF/m/n/9 }\begingroup \escapechar \m@ne \let \MT@subst@\T1/LinuxLibertineT-TLF/m/n/9 \def \par }{}{page.0}{}}

Note in particular the invalid syntax \def \par } !!!!

Ending the document with

\def\latintext{\noexpand\latintext} \end{document}

allows the file to process smoothly. But the page number is then given in arabic, which surely is not what would be wanted in an ACM document containing just bits of arabic.

And there are still failures as the .aux file is read in at the beginning of the next processing run. So this certainly isn’t the complete fix.

Furthermore, it seems that after

\begin{otherlanguage}{arabic} … \end{otherlanguage}

the font never switches back to one for English — if that is what is intended. (As I'm guessing it would be, for an ACM journal article.)

The only way that I can get left-to right text following the arabic is to explicitly use:

\noindent\textLR{% Here is some latin text. }%

The best I’ve been able to do is to end the document with:

\noindent\textLR{% Here is some latin text. }% \def\latintext{\noexpand\latintext} \let\thepage\savethepage \end{document}

where \savethepage is established in the preamble via:

\documentclass{acmart} \let\savethepage\thepage

Now it processes smoothly, as well as on subsequent runs. The .aux file now has:

\newlabel{TotPages}{{1}{\protect \protect \bgroup \beginL \latintext 1\endL \egroup \protect }{}{page.\protect \protect \bgroup \beginL \latintext 1\endL \egroup \protect }{}}

which doesn’t seem best.

But still the page number visible in the PDF remains arabic, not latin.

Perhaps someone else here has some experience with how arabic snippets would best be included in an ACM document.

Hope this helps.

Here is a much better, and complete, solution which can be used more generally, should similar problems be identified.

\documentclass{acmart}

% RRM: solution to a package changing the \pagestyle expansions, % \ps@head and \ps@foot for running headers and footers % The following block can be easily placed into acmart.cls \makeatletter \let\ACM@ps@plain\ps@plain \let\ACM@ps@myheadings\ps@myheadings \let\ACM@ps@headings\ps@headings % \let\ACM@thepage\thepage % probably no longer needed \def\ACM@restore@pagestyle{% \let\ps@plain\ACM@ps@plain \let\ps@myheadings\ACM@ps@myheadings \let\ps@headings\ACM@ps@headings } \AtBeginDocument{\ACM@restore@pagestyle} \makeatother

Test it, followed by:

\usepackage{arabtex} \usepackage[utf8]{inputenc} \usepackage[LFE,LAE]{fontenc} \usepackage[english,arabic]{babel}

or any other packages that mess with \ps@head and \ps@foot

The package that does this kind of change for arabic is arabicore.sty .

The attached files do such a test, over 2 pages. I’ll leave it to someone else to run further tests, for more complicated situations.

Yes. You have to expect this.

Something similar should happen with every piece of structured content, such as list items, citations, bibliography items, table-of-contents, etc.

This is because arabtex is primarily about creating documents using arabic scripts according to arabic typesetting conventions; in particular, right-to-left RTL output — constructed from input read left-to-right LTR.

To do this, arabtex (or one of the packages it loads) will have defined coding to replace all the structural macros, to support what it needs. Many of these will be the same as what acmart.cls also redefines for its own purposes.

Having the two packages loaded together and working correctly will require a detailed study of what each changes, then devising code such as what I did with headers/footers to impose the desired version (ACM or arabtex) into the processing of the particular structure instances.

Of course one also has to decide what “correct” means in each case.

That is, are we

wanting to include arabic RTL content snippets inside an otherwise LTR-based western-style journal article; OR
produce an arabic version (translation, maybe) of an ACM article, that fully complies with arabic typesetting conventions ?

Both situations have merit. Currently acmart is not setup properly for either. It would be a major job to make it so.

I have ideas on how this should be done, in a modular way that allows compatibility with other LaTeX packages. This would then make it a lot easier to further adapt to producing Tagged PDF output, say; as this also needs to patch all of the LaTeX structural macros.

This is surely a question for higher-up to consider.

Hope this helps.

That’d be a pity.

You haven’t told us yet just what that task is, and why you want to use acmart as the document class.

The problem for you with the ACM class is that it does many, many things that you many not need. In particular it loads hyperref which necessarily patches many structures that arabicore.sty also patches. Those patches were developed independently, without regard for the presence of the other package — hence you get incompatibilities.

There are other LaTeX packages and tools that have been designed specifically for Arabic/Farsi/Persian etc. that may suit your requirements better.

For example, try XeTeX and the bidi package. This is meant to be very good.

Or continue to use arabtex and/or Babel (you don’t actually need both) with a document class that isn’t as involved as acmart . (You originally said that things worked with LaTeX's report class.)

Thank you very much for your help.

It’s a pity that ACM currently is incompatible with what you want to do. But thanks for the report, as it highlights an area where the document class can be improved, for the benefit of all.

All the best.

OK. That makes it important that we get the incompatibilities ironed out.

Please try adapting your document to use the stuff in the preamble of the included LaTeX source. I’ve tried to catch all the things that arabicore changes.

It works OK for me with: \title, \author, \date, \section, \subsection, \tableofcontents (Boris, see comment below) and now an {enumerate} list.

Boris. Some technical quirks.

There is a slight problem with numbering sections in the Table-of-Contents. Space between the number and the section-title gets lost. Dunno why yet.

Certainly \@tmpdima is not large enough as \contentsline is being processed.

Here’s where the relevant dimension gets reduced. \r@tocindent1 ->4.185pt {changing \dimen14=18.2pt} {into \dimen14=4.185pt} but I don’t yet know which package is causing this.

Also, it is necessary to put the \tableofcontents \listoffigures \listoftables between \makeatletter … \makeatother since the respective .toc .lof .lot files get entries with \select@language .

This latter aspect would be best coded into acmart.cls , so a user isn’t bothered by it.

I know I can do that in Word, but the quality of the generated PDF is, at least, not compared to that generated with latex.

Hi @ozross

Thank you for your help. But, I can't find the attached file you mentioned. Maybe you forgot to upload it?

Hi @ktobah

The attachments were sent by my mailer, but stripped out by the mailing-list software. This time I'll do it wit the Git interface. This doesn't support .tex files!!! — So I'll rename it to .txt . You'll have to change back to .tex before trying to process it; or just copy what you want from it.

arabic-ACM-test.pdf

arabic-ACM-test.txt

Cheers

I just updated to the latest development version of acmart.cls, rather than what came with TeXLive 2017. The lack of spaces in the ToC is fixed! So is using \makeatletter before reading .toc files, etc.

If you come across any other problems concerning compatibility with Arabi or RTL typesetting, please let me know. Most likely it can be solved with manipulation of pointers, as has been the case so far.

Before offerring this coding to be added into acmart.cls I’m changing the name of the pointers to better reflect where the coding comes from. e.g.

\ACM@LTX@…. means ACM just uses what’s defined by LaTeX \ACM@AMS@…. means ACM uses coding from amsart.cls or amsbook.cls \ACM@Hy@…. means ACM uses coding that has been defined or modified by Hyperref \ACM@AMS@Hy@…. means ACM uses coding from amsart.cls modified by Hyperref etc.

This should make any further development easier, to find where coding has come really come from, so where to look in case other dependencies emerge.

Best regards, Ahmed

Cheers,

Ross
