How to make namespace in lua?

Question

I want to bind static class function to lua. As you know, static class function is something difference with class function. So function call code in lua should be like this...

//C++
lua_tinker::def(L, "Foo_Func", &Foo::Func);

//Lua
Foo_Func()

But I want to call function in lua like this

//Lua
Foo.Func()

Is there any way to use like that? Lua table might be helpful. But I cannot find any references.

Solution 1

Yes, that would be done with a table and is in fact how most modules work when you import them with require.

Foo = {} -- make a table called 'Foo'
Foo.Func = function() -- create a 'Func' function in stored in the table
    print 'foo' -- do something
end
Foo.Func() -- call the function

Solution 2

I think you'll find PiL chapter 26.2 most interesting. If you compile your library to the same name as the table (so filename == modulename) then you can simply require() the module.

Remember that if you declared: Foo.Func = function(this) ... end you can call it: Foo:Func() ( notice the ':' ) , this will pass the Foo table as the first function parameter too.
