Re: SLB vs LuaBind

[beo wulf <beowulf@...>]

Hi Jose,

  I just tried Luabind + lua 5.2 -- doesn't compile (due to function environments, which are not replaced with lexical environments). Any plans to port SLB to work with lua 5.2?

Thanks!

Mmm... sorry, but no. The problem is lua type marshaling with C++
types, there are many ways a type can be "converted" from lua to a C++
function/method signature. Overloading could be possible for different
number of arguments, though, but no for different signatures with the
same number of arguments, and I didn't want to support partial
overloading.

BTW, the search for the proper method to call will add a significant
overhead, SLB is meant to be as faster as possible, near to a
hand-coded wrapper. What I usually do with overloading is register
each function with a different name in lua, which is not as handy as
overload support, but it works.

Cheers,
  JL.

PS: I'm working on registering accessors to instances' attributes,
but, I'm not sure about how use it from lua properly, do you have any
insights?
