About
Lightweight profiler library for c++
You can profile any function in you code. Furthermore this library provide profiling of any block of code.
Build
Prerequisites
For core:
- compiler with c++11 support
- cmake 3.0 or later
For GUI:
- Qt 5.3.0 or later
linux
$ mkdir build
$ cd build
$ cmake ..
$ make
windows
If you use qtcreator IDE you can just open CMakeLists.txt file in root directory.
If you use Visual Studio you can generate solution by cmake command. In this case you should specify path to cmake scripts in Qt5 dir (usually in lib/cmake subdir), for example:
$ mkdir build
$ cd build
$ cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.3\msvc2013_64\lib\cmake" ..
Usage
First of all you can specify path to include directory which contains include/profiler directory. For linking with ease_profiler you can specify path to library.
Example of usage.
This code snippet will generate block with function name and grouped it in Magenta group:
#include <profiler/profiler.h>
void frame(){
EASY_FUNCTION(profiler::colors::Magenta);
prepareRender();
calculatePhysics();
}
To profile any block you may do this as following. You can specify these blocks also with Google material design color or just set name of block (in this case color will be OrangeA100):
#include <profiler/profiler.h>
void frame(){
//some code
EASY_BLOCK("Calculating summ");
for(int i = 0; i < 10; i++){
sum += i;
}
EASY_END_BLOCK;
EASY_BLOCK("Calculating multiplication", profiler::colors::Blue50);
for(int i = 0; i < 10; i++){
mul *= i;
}
EASY_END_BLOCK;
}
