swig(Lua)對STL/C++ library的支持

1、std::string

//demo.h
td::string foo();
void        bar(const std::string &x);

//demo.i
%module demo
%{
#include "demo.h"
%}
%include "std_string.i"
%include "demo.h"

調用

--test.lua
a = demo.foo();
demo.bar(a);

需要注意的是，std_string模塊只支持std::string 和const std::string& ,其餘的指針和非const的引用將最爲SWIG指針處理
2、std::vector

//vectordemo.h
#include <vector>
double average(std::vector<int> v);

//vectordemo.i
%module vecdemo
%{
#include "vectordemo.h"
%include "std_vector.i"
namespace std{
    %template(DoubleVector) vector<<d>double>;
}
%include "vectordemo.h"
%}

--test.lua
vint = vecdemo.DoubleVector(4);
for i=1,4 do
    vint:push_back(i*5);
end;
print(vecdemo.average(vint));
