== This is an example environment for typesetting Arabic ==documents in Mark IV (ConTeXt with LuaTeX). It won't work at all in Mark II (with either pdfTeX or XeTeX).
This is an example style file for typesetting Arabic documentsSave it as "ara-sty.tex" and use "\environment ara-sty" in your document.
% engine=luatex\startenvironment ara-sty
\stoptypescript
To use Now, lets try a specific font just put it under the current directory where you run context, and replace ScheherazadeRegOT with your font file name. Then run 'context arabic.tex' ."Hello World" example:
% OpenType features needed for Arabic\definefontfeature [arab] [mode=node,language=dflt,script=arab, init=yes,medi=yes,fina=yes,isol=yes, liga=yes,dlig=yes,rlig=yes,clig=yes, mark=yes,mkmk=yes,kern=yes,curs=yes]environment ara-sty
% ScheherazadeRegOT is the font file name (without extension) replace it with your preferred font \starttext\font\Arab = ScheherazadeRegOT*arabsetarabic
% For inner paragraph control within an LR paragraph== Hebrew ==
\definestartstop [arabictext] [commands=% {\textdir TRT% \Arab}](Example by Rik Kabel on the mailing list, 2017-12-15)
\def\ArabicText#1{\startarabictext#1\stoparabictext}Depending on the font, correct niqqud placement requires some combination (sometimes all) of the following font features: lang, ccmp, and script.
% For global Arabic <texcode>\definefontfeature [hebrew] [oldstyle] [ lang=heb, ccmp=yes, script=hebr,]\starttext\definedfont[name:EzraSIL*hebrew at 72pt]\setupalign[r2l]טְרוֹפוֹתִי\stoptext</texcode>
\def\ArabicDirGlobal{%\pagedir TRT\bodydir TRT\textdir TRT\pardir TRT}The same settings work well for Narkisim. For David_CLM you only need the script setting.
\def\Arabic{\ArabicDirGlobal\Arab}Correction by Hans, 2017-12-16:
% For separate Arabic-script paragraphsThere is a font feature hebrew already predefined
\definestartstop [arab] [commands=% {\Arab% \ArabicDirPar}]if you have to set a language depends on the font (often dflt is ok).
\showframe[text]This is the predefined set:
اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَ\definefontfeatureآلِ مُحَمَّدٍ وَ ارْزُقْنِي [arabic]الْيَقِينَ وَ حُسْنَ الظَّنِّ بِكَ [semitic-complete]وَ أَثْبِتْ رَجَاءَكَ فِي قَلْبِيوَ اقْطَعْ رَجَائِي عَمَّنْ سِوَاكَحَتَّى لَا أَرْجُوَ غَيْرَكَ وَ لَاأَثِقَ إِلَّا بِك [script=arab]
Here is some mixed {\em Arabic-} (\ArabicText{عربي}) anddefinefontfeatureLatin-script. As you can see, Aleph does a very good job mixing{\em LR} (\ArabicText{يسار-يمين}) and {\em RL} [simplearabic](\ArabicText{يمين [semitic-يسار}) texts. \ArabicText{وsimple]هنا جملة منقطعة في وسط قرينةلاتينية}. Aleph even does a great job breaking Arabicphrases across lines. [script=arab]
