Logger Class Reference

#include <vccc/__log/logger.hpp>

Detailed Description

d for LOGD, i for LOGI, w for LOGW, e for LOGE

supports ostringstream& operator <<

Log.d("Hello, world")                   // Hello, world
Log.d("First: ", 3, " Second: ", 3.14)     // First: 3 Second: 3.14

To use printf-like format, use vccc::Formatter

if ostringstream& operator << is overloaded for user-defined types, it can be printed

Log.d("string: ", std::string("wow!"))   // string: wow!
Log.d("Point: ", cv::Point2i(3,4))       // Point: [3, 4]

std::pair, std::tuple, std::integer_sequence, containers, chrono types, aggregate(since C++17) types can be printed.

Log.d(std::vector<std::vector<int>>{{1, 2}, {3}});  // { { 1, 2 }, { 3 } }
Log.d(std::make_tuple(1, "hello"));                 // { 1, hello }
Log.d(std::chrono::system_clock::now());            // 2021-06-29 14:35:27.917
 
// Since C++ 17
struct foo {
  int x;
  std::string name;
};
Log.d(foo{100, "Tony"});    // { 100, Tony }
