Is there a better solution?
The likeliest cause of loops is still the tex macro expansion, so I
would suggest \tracingall. If that doesn't help, try

starting point :
mtxrun --run vim full:2context.vim
inside a context run you can use
resolvers.resolve(full:2context.vim)

so using:
\ctxlua{os.execute()}

The ConTeXt module for interaction with the statistical programming

the buffer in case \ctxlua is defined (a trick gleaned from a
discussion on the LilyPond

This would be really great, \start/stoplua with % for comments like \ctxlua

@Luigi: You could try to parse the luacode content
at -- as comment

Hi,
is overprinting working in mkiv?
\ctxlua{overprints.enabled=true}
has no effect here or on ConTeXt live. Maybe I'm missing something.
Currently I try to adapt some mkii code to mkiv. Overprinting should
only be enabled if
- a given maximum font size is not exceeded and
- the current text

I attach a minimal example in the mail.
Is there anything wrong in the document? Thank you.

I think this is a bug in converters.alphabetic function, it doesn't
handle zero and seem to convert 1-0 2-1 etc. The following code:
\ctxlua{converters.alphabetic(0,arabic)}
\ctxlua{converters.alphabetic(123456789,arabic)}
gives 0 ٠١٢٣٤٥٦٧٨, while it should give ٠١٢٣٤٥٦٧٨٩
, it doesn't
