Here is a possible implementation (modification of the existing function).
static int luaB_auxwrap (lua_State *L) {
lua_State *co = lua_tothread(L, lua_upvalueindex(1));
int r = auxresume(L, co, lua_gettop(L));
if (r < 0)
{
/* I JUST ADDED THOSE 3 LINES */
luaL_where(L,1);
lua_insert(L,-2);
lua_concat(L,2);
/* END OF MODIFICATION */
lua_error(L); /* propagate error */
}
return r;
}
BTW, I spoke about the "[chunk id]:<line>: message" format, but is this a de
facto standardized
message format that all errors raised by the core or the standard libraries
should (be expected to)
follow ?

Benoit.
