Hi Hans Thanks for the code so that we can use fonts in Plain and LaTeX. I just had two questions 1- I got the code from Khaled. How can I get the beta myself from your repository? I just joined ConTeXt mailing list. 2- Your code works fine but if in LaTeX, I compile a document like %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \documentclass{article} \pagedir TRT \bodydir TRT \pardir TRT \textdir TRT \directlua { dofile(kpse.find_file("luatex-fonts.lua","tex")) } \font\body=file:XBZar.ttf:mode=node;script=arab;language=ara;+init;+medi;+fina;+liga;+rlig;+mark;+mkmk at 14pt \def\normalfont{\body} \AtBeginDocument{\body} \begin{document} این یک آزمایش است که در حال وقوع است. \section{مقدمه} \end{document} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Then it gives this error ! LuaTeX error /home/vafa/texmf/tex/luatex-fonts/font-def.lua:337: attempt to c all field 'read_from_afm' (a nil value). relax l.16 \section{مقدمه} ? Do you know how I can resolve this issue. The issue is when you use \section and similarly when you use \chapter, \textbf, \begin{....} \end{.....} If I can resolve this, Then I will be writting a LaTeX interface for the fonts.
