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!

Create Lua bindings for your C++ code easily - my improvements

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

luabind-deboostified's Issues

GCC: wrong number of template arguments in out_value_policy.hpp

When building on Linux with GCC following error occures:

out_value_policy.hpp:220:33: error: wrong number of template arguments (1, should be 3)
    storage_.template construct<T>();

out_value_policy.hpp:241:33: error: wrong number of template arguments (1, should be 3)
storage_.template construct<T>();

Incorrect function overloading

If you have function with default arguments, like this:

void Kill(CScriptGameObject* who, bool bypass_actor_check = false);

It would be exported to Lua as a functions that accepts two arguments, but not one. If you will try to call it with one argument it will crash.

In the previous luabind version you could use casts to fix the problem:

.def("kill", (void (CScriptGameObject::*)(CScriptGameObject*))&CScriptGameObject::Kill)
.def("kill", (void (CScriptGameObject::*)(CScriptGameObject*, bool))(&CScriptGameObject::Kill))

In this new version this doesn't help. The second parameter will be filled with trash.

How to deal with missing allocator?

I have tried to use this in my project, and I have found the extern alloc_func allocator which is missing... (my program is crashing on an attempt to load of LuaBind and fails on allocator as "calling pure-virtual method"). Where I can take the proper allocator and it's context to make this thing working?

Permissive mode

The previous version of luabind was very permissive for script errors.
For example, you have a function and it is exported to Lua:

void func(int arg1, int arg2); // functions itself

def("func", &func) // export

If you pass to this functions wrong parameters, like this:

func("__") -- Passing string instead of a number. This is wrong!!!
		   -- The second argument is forgotten. This is wrong too!!!

Nothing will happen. The script just hang and that's all. No crash will proceed.

But in this new version it crashes on every error and doesn't have a permissive mode, which is bad for compatibility.

We should add some sort of permissive mode that ignores the errors like it was before.
