Hello,
I tried to pass an argument to my_lua_function but I want it as verbatim
argument because it may contain any characters TeX doesn't like.
It's ok with this callback for reading just one line after \Cmath:
\def\Cmath{\directlua{luatexbase.add_to_callback("process_input_buffer",parseCmath,"parseCmath")}}
\directlua{
function parseCmath(line)
luatexbase.remove_from_callback("process_input_buffer","parseCmath")
return my_lua_function(line)
end
}
\begin{document}
\Cmath
1/2
\end{document}
But I'd want to do the same with this syntax \Cmath{1/2}
Is it possible with a callback or anything else ?
Thank's for ideas.
