asynclogger's Introduction

AsyncLogger

Modern Asyncronous Logger using C++20 and std::format (falls back on fmt::format if not available) without using macro's! Uses std::source_location to get the location where a log was made.

CMake variables

USE_FMT : Force AsyncLogger to use fmt formatting instead of std formatting if it's available.

How to use

Very simple example application showing how to implement it.

main.cpp

#include "AsyncLogger/Logger.hpp"
#include <filesystem>
#include <iostream>

// expose LOG, LOGF, eLogLevel::DEBUG, eLogLevel::INFO, etc...
using namespace al;

void COUT_LOG(LogMessagePtr msg)
{
    const auto& location = msg->Location();
    const auto file = std::filesystem::path(msg->Location().file_name()).filename().string();

    std::cout << "[" << file << ":" << location.line() << "] " << msg->Message();
}

int main()
{
    Logger::Init();
    Logger::AddSink(COUT_LOG);

    LOG(INFO) << "Test " << 1 << 2 << 3 << " some float (" << 3.5f << ")";

    Logger::Destroy();

    return 0;
}

Logs the following output:

[main.cpp:20] Test 123 some float (3.5)
