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.
that's just a side effect of the engines dafaulting to some plain name i.e. tex->plain.fmt, pdftex->pdftex.fmt, luatex->luatex.fmt, etc so, although luatex can use a plain.fmt format, in practice it would be luatex.fmt (now that we have engine subpaths a non-clashing plain.fmt would be posible but that's all dependent of the cnf file) concerning plain itself ... i guess that in most macropackages you can use plain-like macros; it would be interesting to know what functionality plain offers that macro packages don't provide too; the main advantage of plain is that it's small and very stable, but any luatex related font code will make plain way bigger, slower and less stable
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.
it would probably also need something \input a-lot-of-extra-lua-code \font\test=zar.ttf[plus enabling arabic features] scaled\magstep0 and probably more since plain tex is meant as basis for typesetting an english book and not arabic ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
