Forbid word breaking (ConTeXt)

Question

In the following example

\definefont[Shehkl][name:Scheherazade*arabic at 15pt] % or file:amiri-regular.ttf*... file:alq.ttf

\definestartstop[Arab][commands=\setups{Arabic}]
\def\Arab{\doArab}
\def\Arab[#1]{
\startArab 
\noindentation
            \setupalign[r2l]\Shehkl#1
\stopArab
}

\starttext

--------------------------------------------------------------------------------------------- (Fitra -\Arab[فطرة])

\stoptext

the last bracket in (Fitra -\Arab[فطرة]) is set into the next line - a mistake of course. One way to avoid that (caused by not correctly handling arabic?) would be to put it all into something like \neverbrakethis[] - which I know from LaTeX, what is the equivalent here - or are there better solutions for this?

Answer 1

I don't know much about arabic typesetting, but your ConTeXt source does not appear to be right. Why not use the following, which is simpler and much more direct:

\usemodule[simplefonts]

\definesimplefont[arabicfont][Scheherazade][size=15pt, features=arabic]

\startsetups arabic
  \righttoleft
  \language[ar]
\stopsetups

\definestartstop
  [arabic]
  [commands=\setups{arabic}, style=\arabicfont]


\starttext

English text \arabic{arabic text} english text

\startarabic
  .... arabic paragraph
\stoparabic

\stoptext

Notes:

1. Ideally, in ConTeXt you want to switch to a complete typescript rather than just switch the main font. With typescripts, font variants such as bold, italic, sans bold, work correctly. I don't know if those variants make sense for Arabic.

2. I am using the simplefonts module simply because I find it more convenient compared to the low level font commands.
