Re: [luatex] macros to invoke lua in LaTeX

[Elie Roux]

Taco Hoekwater a écrit :

\ifnum\luatexversion<40
  \def\directlua{\primitive\directlua0}
\fi
      

Just marked deprecated. But that comes with a terminal message
that you will want to avoud.
  

Sure... but then I don't understand why we should put a 
\ifnum\luatexversion<40?
