Hi Manuel, All,
I find that the mplibcode environment in LuaLaTeX is missing
an important feature. There is no way to call Lua from inside it!
I have investigated the code and found that the use of the verbatim-
environment is preventing this. But, there is a way to install a Lua-calling
mechanism.
In the Lua-code of of luamplib. the function addline needs to be patched to
catch a dolua-command, extract the Lua-function, call it and finally feed the
result
in the normal way to mplib.
I have done that!
Is there an interest for such a feature.? What kind of syntax would be
preferred?
It would be possible to write:
\begin{mplibcode}
. . .
dolua(generatesomecommands(with, and, that))
. . .
\end{mplibcode}
regards
Keith
