About

Asynchronous, 'crash safe', logger that is easy to use

Examples

set up basic logging in a C++ project

$ g3log is a library, not a CLI tool. Include it in your CMakeLists.txt: find_package(g3log CONFIG REQUIRED) and link target_link_libraries(myapp g3log)

write log messages from C++ code$ LOG(INFO) << "Application started"; LOG(WARNING) << "Potential issue"; LOG(FATAL) << "Critical error";

configure log file output location$ auto worker = g3::LogWorker::createLogWorker(); auto handle = worker->addDefaultFileLogger("myapp", "./logs");

add custom log sink for remote logging$ auto sinkHandle = logWorker->addSink(std::make_unique<CustomSink>(), &CustomSink::receiveMessage);

catch and handle fatal crashes safely$ g3::installCrashHandler(); // Ensures logs are flushed before crash dump on Windows/Linux
