YSL

💄 YAML Stream Logging, structured Google logging with YAML!

Integrated in yaml-cpp on this branch: https://github.com/MacroBull/yaml-cpp/blob/mymod/include/yaml-cpp/contrib/ysl.hpp

Usage

Use macro YSL instead of LOG, you get a YAML::Emitter-like stream with Google logging output:

#include "ysl.hpp"

#include <yaml-cpp/stlemitter.h>

YSL_FSCOPE(INFO, "Hello Container");
YSL(INFO) << "hello" << YAML::FloatPrecision(3) << std::map<int, float>{{1, 3.4f}, {2, 6.78f}, {3, 9.0f}};
YSL(INFO) << "PI" << YAML::Flow << std::vector<int>{3, 1, 4, 1, 5, 9, 2, 6};

Output:

I0926 15:42:30.953778 12990 main.cpp:19] --- # --------------- Hello Container: 0 ------------ # ---
I0926 15:42:30.953805 12990 main.cpp:20] hello:
I0926 15:42:30.953812 12990 main.cpp:20]   1: 3.4
I0926 15:42:30.953830 12990 main.cpp:20]   2: 6.78
I0926 15:42:30.953848 12990 main.cpp:20]   3: 9
I0926 15:42:30.953855 12990 main.cpp:21] PI: [3, 1, 4, 1, 5, 9, 2, 6]
