luabind-deboostified's Introduction

luabind

This is a customized luabind fork that's used by X-Ray Engine. Comparing to the old version (presumably beta7-devel-rc4) previously used in X-Ray, this version speeds up xrGame (the most heavy engine module) compilation by about 100%.

Currently, at least the following compilers are supported:

MSVC 2015
Clang/LLVM 3.6.0
G++ 4.9

If you can confirm support on another platform, please let me know!

Variadic templates.
Got rid of the arrays created in invoke.
All boost removed.
No backward compatibility to any old or faulty (MS) compilers.
This is 24mb of Intellisense db versus close to 90mb with original luabind, also Intellisense is not crippled by boost preprocessor usage.

Important: This is not drop in replacable.

The template parameters to class class_ work a bit differently to the original (Wrapper and Holder have a specific index, if you don't want one of them, use null_type and/or no_bases)
The policies are not implemented as functions with a wrapped integer argument, they're aliases to policy lists containing exactly the one respective policy
The error callback is no longer the function that is pushed as pcall's error handler, but is instead called to push the error handler onto the stack
Exceptions thrown by luabind will now carry the error message, it no longer has to be pulled from the lua stack separately
Since the requirement to Boost.Optional has been dropped, object_cast_nothrow now has a mandatory default argument that is returned when the cast failed. Use boost::optional() for that to get the old behavior
