XNLogger

XNLogger is a simple logging library for C++ that provides colorful output to the console and writes logs to a file. It supports three log levels: INFO, WARNING, and ERR.

Features

• Colorful console output for eye-catching logs
• Logs are written to a file for easy storage and analysis
• Supports three log levels: INFO, WARNING, and ERR
• Easy to use with variadic functions for logging messages with formatting

Usage

1. Include the XNLogger library in your C++ project.
2. Initialize the logger by calling logger::init() function (not shown in the code snippet).
3. Start logging messages using the logger::info(), logger::warning(), and logger::error() functions.
4. Provide a log message with optional formatting using the same syntax as printf().
5. Logs will be displayed in the console with colorful output and written to a file for future reference.

Example

#include "xnlog.hpp"

int main() {
    // Log an info message
    logger::info("This is an info message.");

    // Log a warning message with formatting
    int errorCode = 404;
    logger::warning("Warning: Failed to load file. Error code: %d", errorCode);

    // Log an error message
    const char* errorMessage = "File not found";
    logger::error("Error: %s", errorMessage);

    return 0;
}

Output

[2023-04-25 15:30:45] [INFO] This is an info message.
[2023-04-25 15:30:45] [WARNING] Warning: Failed to load file. Error code: 404.
[2023-04-25 15:30:45] [ERROR] Error: File not found.

Logs are displayed in the console with colorful output to easily identify the log level. They are also written to a file "log.txt" in append mode for future reference.
