##What is XLIB?

---

Xlib is a collection of c + + commonly used functions and basic components.
It is for the purpose of cross-platform and reuse.
Including the logging system, thread pool, timer, TCP communications, and so on.
You can easily use it in your program.

##Usage

###1. log ###2. thread ###3. timer ###4. socket

log

    //set log level
    LOG_SET(LOG_LEVEL::L_ALL); 
    //you can set the specified log file to record
    XLog::setWrite(true, XFileUtil::getCurrentPathWithPrefix().append("xliblog"));
    /**usage example.
        LOG_I------'I' means info. 
        And by that analogy:
        LOG_D------'D' means debug.
        LOG_E------'E' means error.
        ...
    */
    std::string s="this is a log test!";
    LOG_I("%s",s.c_str());
    

thread pool

    auto fun = []
    {
        std::this_thread::sleep_for(std::chrono::seconds(rand()%50));
        std::thread::id tid = std::this_thread::get_id();
        auto t = XString::formatTime(XTime::getTimeFromTimestamp_milliseconds(XTime::getTimestamp_milliseconds(),8),TIME_F::T_DEFAULT);
        LOG_I("thread_id=%d,%s",tid,t.c_str());
    };
    /** XThreadPool's first constructor parameter means thread max number,
        the second is task max number,
        the last is Whether begin immediately.
    */
    auto pool = std::shared_ptr<XThreadPool>(new XThreadPool(5,5,true));
    
    pool->addTask(fun);
    pool->addTask(fun);
    pool->addTask(fun);
    pool->addTask(fun);
    pool->detach();

timer

    /**at first,you defined a timer's attributes:
        1.repeate number
        2.the number of seconds 
        3.the callback
    */
    XTime::doPertime(-1, 0.5,[]
    {
        LOG_D("this is a timer,1 second 2 times");
    } );
    
    //then ,you add a loop to do it.
    auto loop = []
    {
        while (true)
        {
            XTimer::getInstance()->mainLoop();
        }
    };

Socket

    /** Below is the tcp server test code*/
     xlib::net::XSocketTCP server;
     server.startServer(4435);
     
    //if you take client,you can do as follow
    
    auto tcp = std::shared_ptr<net::XSocketTCP>(new net::XSocketTCP);
    tcp->startClient(net::_server(2347,"120.27.94.221"),true);
    std::string chutf8 = "这是一个字符串";
    auto s = XUtf8::utf8ToUnicode(chutf8);
    LOG_I(s.c_str());
    tcp->Send(chutf8.c_str(), sizeof(chutf8));

##Notes

1. Compile environment: need GCC 4.8 or above, more than clang3.1.
2. Test: the whole project, on the MAC and centos test has no problem. Perform the make, then run the generated script.
