Lua Socket Event

LuaSocketEvent the Lua Socket Event, Asynchronous Socket. support platform for Linux, MacOSX, Windows, IOS, Android, Cocos2d-x.

LuaSocketEvent supports data and message in two formats, data are the original data, the message is 4 bytes unsigned int little endian and message content

Notice

Please implement lua_lock and lua_unlock for thread safe.

Instructions

Server

nc -l 8888

Client

local socketevent = require("socketevent")

sock = socketevent.tcp()

sock:on("connect", function(event)
	print("connect")
end)

sock:on("data", function(event)
	print("data: " .. event.data)
end)

sock:on("close", function(event)
	print("close!")
end)

sock:on("error", function(event)
	print("error: " .. event.error .. ", " .. event.message)
end)

sock:connect("127.0.0.1", 8888)

sock:send("hello server\n")

Run Data Client

lua -i test_data.lua

Client Send Data

> sock:send("hello server\n")

Message Server

printf "\x0c\x00\x00\x00hello client\x0c\x00\x00\x00hello client" | nc -l 8888 | xxd

Message Client

......

sock:on("message", function(event)
	print("data: " .. event.data)
end)

......

sock:sendmessage("hello server")

Build LuaSocketEvent Library

*nix binary

gcc -o socketevent socketevent.c -I/usr/local/include -L/usr/local/lib -llua -lm -ldl -lpthread

linux

gcc -fPIC --shared -o socketevent.so socketevent.c -lpthread

macosx

gcc -o socketevent.o -c socketevent.c
gcc -bundle -undefined dynamic_lookup -o socketevent.so socketevent.o

windows

1. create lua-5.1.4\build.bat file

    cd src
    cl /O2 /W3 /c /DLUA_BUILD_AS_DLL l*.c
    del lua.obj luac.obj
    link /DLL /out:lua53.dll l*.obj
    cl /O2 /W3 /c /DLUA_BUILD_AS_DLL lua.c luac.c
    link /out:lua.exe lua.obj lua53.lib
    del lua.obj
    link /out:luac.exe l*.obj
    cd ..
   

2. open VS2013 developers tools, run build.bat

3. copy socketevent.c to lua-5.1.4\src

4. create socketevent.dll

    cl /O2 /W3 /c /DLUA_BUILD_AS_DLL socketevent.c
    link /DLL /out:socketevent.dll socketevent.obj lua53.lib
   

android

ios

Cococs2d-x

windows cocos-simulator-bin

1. build source to socketevent.dll

2. copy socketevent.dll to C:\Program Files (x86)\Cocos\cocos-simulator-bin\win32

3. main.lua join

    require("socketevent")
   

4. using socketevent

mac simulator

1. Xcode open frameworks/runtime-src/proj.ios_mac/LuaTest.xcodeproj

2. Classes dir create socketevent.h socketevent.c file

3. lua_module_register.h join

    extern "C" {
    	#include "socketevent.h"
    }
   

4. lua_module_register function join

    luaopen_socketevent(L);
   

5. Xcode build for Mac
