History 2.1 DS Added [hidden] attribute Added OnError property Fixed MULTIRET lua call Fixed function luaL_testudata 2.0.3 DS Fix XE5 - Added Pointer cast for RegisterFunc 2.0.2 DS Fix: added missing lua_isinteger function 2.0.1 DS Fix: fixed Register function Added Example 6 - Call a Lua function 2.0 DS Updated Lua Lib to 5.3.0 Rewrite of Delphi register functions Removed Class only functions Removed a lot of convenience overloaded functions Support for mobile compiler 1.4 DS Rewrite of Lua function calls, they use now published static methods, no need for a Callbacklist required anymore Added Package functions Added Class registering functions 1.3 DS Improved Callback, now uses pointer instead of object index Modified RegisterFunctions to allow methods from other class to be registered, moved object table into TLua class 1.2 DS Added example on how to extend lua with a delphi dll 1.1 DS Improved global object table, this optimizes the delphi function calls 1.0 DS Initial Release

This is a Lua Wrapper for Delphi XE5-D10.1 which automatically creates OOP callback functions for Delphi <-> Lua:

uses VerySimple.Lua, VerySimple.Lua.Lib;

type TMyLua = class(TVerySimpleLua) published function HelloWorld(LuaState: TLuaState): Integer; end;

function TMyLua.HelloWorld(LuaState: TLuaState): Integer; var ArgCount: Integer; I: integer; begin ArgCount := Lua_GetTop(LuaState);

writeln('Delphi: Hello World'); writeln('Arguments: ', ArgCount);

for I := 1 to ArgCount do writeln('Arg1', I, ': ', Lua_ToInteger(LuaState, I));

// Clear stack Lua_Pop(LuaState, Lua_GetTop(LuaState));

// Push return values Lua_PushInteger(LuaState, 101); Lua_PushInteger(LuaState, 102); Result := 2; end;

var MyLua: TVerySimpleLua;

begin MyLua := TMyLua.Create; MyLua.DoFile('Helloworld.lua'); MyLua.Free; end;

helloworld.lua

print("LuaDelphi Test"); p1,p2 = HelloWorld(1,2,3) print "Results:"; print (p1); print (p2);
