将Lua编译为C ++除了避免“extern C”和get“C ++ exception”，有什么好处？ [英] What is the benefit to compile Lua as C++ other than avoid 'extern C' and get 'C++ exception'?

问题描述

我在Lua很新，我想使用C ++将Lua嵌入到我们的游戏项目中。第一件事我注意到，Lua被允许编译为C ++代码，并从文档，我知道，这将消除'extern C'环绕Lua的头，并且错误处理将是C ++异常，而不是longjump / setjump。

I'm quite new in Lua, and I want to embed Lua into our game project using C++. The first thing I notice, Lua is allowed to be compiled as C++ code, and from the doc, I've learned that this will eliminate the 'extern C' wrapping around Lua's headers, and also the error handling will be C++ exception instead of longjump/setjump.

我的问题是，除了这两个区别之外，将Lua代码编译为C ++代码有什么其他真正的好处吗？这两个不真正说服我，因为，1）它不打扰我用'extern C'包装c头，2）我们的项目不允许异常，所以我必须改变在luaconf.h使用

My question is, besides these two differences, is there any other real benefit to compile Lua code as C++ code? These two don't real convince me, as, 1) it doesn't bother me to wrap c headers with 'extern C', 2) our project doesn't allow exception, so I have to change in luaconf.h to use longjump/setjump any way.

推荐答案

这些是将Lua编译为C ++的好处。 externC事情甚至不是真正的点;它都是关于异常处理。

Those are the benefits of compiling Lua as C++. The extern "C" thing isn't even really the point; it's all about exception handling. And while your application forbids exceptions, not every C++ application does.

如果你使用C ++的所有 ，你必须采取步骤以防止异常通过Lua（不是世界上最简单的东西，除非你使用像Luabind这样的包装器）或者将Lua编译为C ++。

If you're using all of C++, you either have to take steps to prevent exceptions from passing through Lua (not the easiest thing in the world unless you're using a wrapper like Luabind) or to compile Lua as C++.

没有将Lua编译为C ++的其他好处。异常处理是为什么Lua可以编译为C ++的原因。

There are no other benefits of compiling Lua as C++. Exception handling is the reason why Lua can be compiled as C++.
