[luatex] % character in \directlua

[Yannis Haralambous]

Hi everybody, and sorry for my mailer: it gives me only two choices, either "text" (my current choice, believe it or not) or "rtf".

I'm writing to ask whether there is a more elegant way to use a % in a \directlua argument (I need the Lua modulo operator)
besides changing the catcode of % to 12 around the \directlua command:

\begingroup
\catcode`\%=12
\directlua{texio.write(5 % 2)}
\endgroup

I have tried \%, \string%, nothing works besides the code above.

cheers

Yannis
