TeX engines to decide the best one. Can anyone send a samplwe file for typesetting Arabic in Plain TeX over luatex where the alphabets are not isolated?
1. Mixed-up categories: Plain TeX is a macropackage, luaTeX is an engine.
No. It is not. When someone uses Plain TeX in an engine, he would say Plain TeX over the engine-name. It seems you know very little about Plain TeX.
Your question was not clear enough and it's read as you want to compare TeX (the program) with LuaTeX (the program). You should say Plain TeX in or with LuaTeX.
4. Without a more precise question I cannot really recommend which way to go from here.
This is a sample file, I am looking for.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \pagedir TRT \bodydir TRT \textdir TRT \pardir TRT \font\test=zar.ttf scaled\magstep0
هل انت کیقک؟ \end %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
But I do not know how to define the font so that Arabic alphabets are not isolated.
You use in ConTeXt features to enable functions like kerning, ligatures etc. In the higher level interface you do this with "interface=..." but with the font primitive this is done with \font\...=...*featurename and in your example \font\test=zar*arabic scaled\magstep0 \test % you forgot to enable the font Wolfgang
