tolua already provides tags to be included in the .h file.
it is an undocumented feature :-(

you can include tags, in comments, in the real .h file.
there are three types of tags (case insensitive).

block tags:
/* tolua_begin */

            <-- code to be parsed by tolua

/* tolua_end */

or line tag:

<code to be parsed by tolua>       /* tolua_export */

the .pkg still have to exist, but it can have directives to include tagged header files as in:


as an example, consider:

real header file: example.h

#include "something.h"

#define    N   100            // tolua_export

// tolua_begin
class T {
 T ();

// tolua_end

.pkg file: example.pkg

i prefer to keep everything in the .hpp files rather than having to maintain
extra package-files.
i extended tolua to help with this. namely, i added to the existing
TOLUA_BEGIN / TOLUA_END a mechanism to register (parts of) classes:

it works like this:

class ClassName : public BaseClass
        // stuff i don't want to expose to lua
        void InternalFunction();

        // now comes the "lua interface" of the class
        // TOLUA_CLASS(ClassName:BaseClass)
        void ExposedFunction();
        // TOLUA_END

i also made some patches to let tolua understand some more standard C++
constructs (such as enums with trailing commas)
basically i'd wish that tolua would just understand any C++ construct that
is valid in C++.
