Re: toLua : How do you add helper functions to the package file

["Ariel Manzur" <puntob@...>]

You can add literal code on the pkg that will show up on the "main"
section of the output, like this:

${
static int my_helper(lua_State* L) {

   return 1; // very helpful
};
$}

'my_helper' would be a regular lua_Function, like all the other
wrappers tolua generates. If "${ ... $}" doesn't work, try adding
every line with a "$" at the beginning (like when you do $#include
"...")
Then, you add code into the function that registers all the wrappers
into the lua state, at the bottom, like this:

$<
tolua_function(tolua_S, "my_helper", my_helper);
$>

then you can use 'my_helper' from lua. You can (probably) nest the $<
... $> blocks inside classes or namespaces to have methods and stuff.

that should work on tolua..
