Description

Logging library for C++ with the following features:

1. You can create your own log handler class, thereby overriding the destination of the log file, etc.
2. You can create your own log layout class, thereby changing the log message format

Fuck knows why I did it, but it seems to work.

Prerequisites

• C++17 or higher
• CMake >= 3.16

Example

Two logger creation with different location but with same format and terminal output.

#include <ut/logger/logger.h>
#include <ut/logger/defaultmessagelayout.h>
#include <ut/logger/filerotateloggerhandler.h>
#include <ut/logger/terminalloggerhandler.h>

using UT::Logger;

int main(int argc, char* argv[]) {
    // Logger handler with file rotation
    auto commonFRLoggerHandler = std::shared_ptr<UT::FileRotateLoggerHandler>(new UT::FileRotateLoggerHandler());
    commonFRLoggerHandler->setLogPath("log/common.log");
    commonFRLoggerHandler->setMaxLogBytes(100);
    commonFRLoggerHandler->setMaxLogs(3);

    auto customFRLoggerHandler = std::shared_ptr<UT::FileRotateLoggerHandler>(new UT::FileRotateLoggerHandler());
    customFRLoggerHandler->setLogPath("log/custom.log");
    customFRLoggerHandler->setMaxLogBytes(100);
    customFRLoggerHandler->setMaxLogs(3);

    // Terminal logger handler
    auto terminalLoggerHandler = std::shared_ptr<UT::TerminalLoggerHandler>(new UT::TerminalLoggerHandler());

    auto messageLayout = std::shared_ptr<UT::DefaultMessageLayout>(new UT::DefaultMessageLayout);

    // Register logger
    Logger::create("common", messageLayout, { commonFRLoggerHandler, terminalLoggerHandler });
    Logger::create("custom", messageLayout, { customFRLoggerHandler, terminalLoggerHandler });

    Logger::write("common", "INFO", "Hello, World!");
    Logger::write("custom", "ERR", "My error message");

    return 0;
}
