cpp_timer
An efficient, convenient and header-only timer for cpp.
Intro
Cpp_timer is useful for cpp programmers to profile their code's performance. It's implemented using std::chrono in c++11. Here are some features supported:
- Header only. So it's easy to be used in your code.
- Easy to turned off/on. The timer can be invoked by '-DCPPTIMER' when compiling. You need not comment out your timer code if you don't want them.
- Macros to profile a block of codes.
- Macros to profile blocks of codes in different position.
Usage
To profile a block of codes, just add TIMER_INIT(name) and TIMER_ELAPSED(name) in your code.
TIMER_INIT(name)
// some codes here
TIMER_ELAPSED(name)
We also provide accumulate timers for blocks of codes.
TIMER_INIT(name1)
TIMER_INIT(name2)
for (int i = 0; i < 10; ++i) {
TIMER_RESET(name1)
// some code here
TIMER_COUNT(name1)
TIMER_RESET(name2)
// some code here
TIMER_COUNT(name2)
}
TIMER_REPORT_COUNT(name1)
TIMER_REPORT_COUNT(name2)
To use the timer, compile your code with
g++ -std=c++11 -DCPUTIMER
If you don't want to the code to print out something in your screen, just leave -DCPUTIMER out. It's convenint for you to release your code.
Installation
It's header only, so just copy to the include folder in your project.
