测试环境

VS2022 + Qt5.14.2

示例

#include <easy/profiler.h>
#include <easy/arbitrary_value.h>
void func() {
   EASY_FUNCTION(profiler::colors::DarkCyan);
   uint64_t sum = 0;
   EASY_VALUE("sum", sum, profiler::colors::Blue);
}

void thread() {
   EASY_THREAD("Resource loading");
   for(itn i = 0; i < 50; ++i) {
       EASY_END_BLOCK;
       EASY_NONSCOPED_BLOCK("Frame", true, 15., profiler::ON, -5.f, profiler::colors::Red);	// 一帧
	   EASY_EVENT("Resources Loading!", profiler::colors::Cyan); 
       EASY_TEXT("Test String", "Some short text. Hey!", profiler::colors::Red);
   }
   EASY_END_BLOCK;
}

void main() {
	// start
	EASY_PROFILER_ENABLE;
	EASY_MAIN_THREAD;
	profiler::startListen();
	
	// call
	// ...
	
	// save file
	auto blocks_count = profiler::dumpBlocksToFile("test.prof");
    std::cout << "Blocks count: " << blocks_count << std::endl;
}

prof转json

JsonExporter js;
js.convert(filename, output_json_filename);
