CppTimer

It is the simple static C++ timer library based on the boost thread library to make your life easier. The CppTimer provides a high-level programming interface for timers.

How to build:

Install boost libraries. Pay attention to the version of installed libraries and version of thread library in submodule. They must be equal (if it's not, choose the correct version in the thread submodule).

 git clone https://github.com/Humminghead/CppTimer.git
 cd CppTimer
 git submodule init 
 git submodule update
 cmake CMakeLists.txt 
 make
 make install

How to use:

Create simple cpp project with cmake. Add in to your cmake next lines:

target_link_libraries(${PROJECT_NAME} PRIVATE CppTimer pthread)

and replace the main.cpp lines with the following text:

#include <CppTimer/timer.h>

#include <chrono>
#include <iomanip>
#include <iostream>
#include <thread>

using namespace std;

std::string format(int v)
{
    return v > 9 ? std::to_string(v) : "0" + std::to_string(v);
}

std::string time()
{
    std::time_t t = std::time(0);  // get time now
    std::tm* now = std::localtime(&t);
    return format(now->tm_hour) + "-" + format(now->tm_min) + "-" + format(now->tm_sec);
}

int main()
{
    std::cout << time() << ": start" << std::endl;
    CppTimer::CppTimer timer(1, [] { std::cout << time() << ": event" << std::endl; });
    timer.run();
    std::this_thread::sleep_for(std::chrono::seconds(3));
    timer.stop();
    std::cout << time() << " :stop" << std::endl;
    return 0;
}

Out:

12-00-20: start
12-00-21: event
12-00-22: event
12-00-23: event
12-00-23 :stop
