export2lua

• 使用libclang读取cxx头文件，自动生成符合luatinkerE语法的导出语句
• 支持luatinkerE的所有新特性，包括函数重载及默认参数导出
• 需要定义一个空的export_lua,用来指示哪一行的定义需要导出到lua

---

• use libclang read cxx header file ，auto gen c++ code export to lua for luatinkerE
• support all feature of luatinkerE， include overload function and default params output
• need define a empty macro named export_lua,will gen export code which line "export_lua" used

---

usage： export2lua[cppfile][-Iheaderdir] ...[-Iheaderdir]

• [--cpps=filename] use ';' to separate source files from file like a.cpp;b.cpp;test/c.cpp;
• [--include=filename] use ';' to separate include dirs from file like -Itest;-I../game;
• [--output=filename] output file name
• [--exportclass=filename] use ';' to separate which class need export from file
• [--keyword=export_lua] keyword default is export_lua, if set to empty will output all decl
• [--skip_default_params] not output default_params
• [--skip_function] not output function
• [--skip_class] not output class
• [--skip_namespace] not output namespace
• [--skip_var] not output var
• [--skip_field] not output class field
• [--skip_enum] not output enum
• [--skip_method] not output method
• [--skip_method_static] not static method
• [--skip_con] not output Constructor
• [--skip_overload] not output overload function
• [-v] will output DEBUG info)

example:

读取tests/test.h文件，增加include作为头文件目录，结果重定向到a.txt
export2lua tests/test.h -Iinclude > a.txt

读取tests/test.h文件，增加include作为头文件目录，结果输出到a.txt
export2lua tests/test.h -Iinclude --output=a.txt

读取cpps.txt中列出的所有文件，增加header.txt中列出的所有目录作为头文件目录，结果输出到a.txt
export2lua --cpps=cpps.txt --include=header.txt --output=a.txt

读取cpps.txt中列出的所有文件，增加header.txt中列出的所有目录作为头文件目录，取消关键字查找改为全部导出, 导出类名必须包含在export.txt中， 结果输出到a.txt
export2lua --cpps=cpps.txt --include=header.txt --output=a.txt --keyword= --exportclass=export.txt

in cxx：

#define export_lua  
export_lua class test    
{   
export_lua test(){}  
export_lua void member_func(int);  
};  
export_lua int global_func();  

autogen:

//this file was auto generated, plz don't modify it
#include "lua_tinker.h"
#include "tests/class2.h"
void export_to_lua_auto(lua_State* L)
{ 
lua_tinker::def(L, "global_func",&global_func);
lua_tinker::class_add<test>(L, "test",true);
lua_tinker::class_def<test>(L, "member_func",&test::member_func); 
lua_tinker::class_con<test>(L, lua_tinker::constructor<test>::invoke);
}
