# 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
|
|
|
|
```bash
|
|
$ 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:
|
|
```batch
|
|
$ 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:
|
|
```cpp
|
|
#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):
|
|
```cpp
|
|
#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;
|
|
}
|
|
```
