Loggy: Header-Only C++ Logging Library

Loggy is a lightweight, header-only C++ logging library. It supports multithreaded environments and includes color coding for enhanced readability.

Features

• Header-only: No need for additional compilation steps or external dependencies.
• Multithreaded: Designed to work seamlessly in multithreaded applications.
• Color Coding: Log messages are color-coded for different log levels, aiding quick identification.
• Customizable: Easily configure log levels, timestamp formats, source information formats, and log message formats.

Getting Started

Prerequisites

• C++11 or later compiler

Build project

mkdir build & cd build
cmake ..

Usage

First you'll have to include loggy.h into your project:

#include <loggy.h>

A full example can be found in the example.cpp file.

Set the default log level:

LOGGY_SET_DEFAULT_LOG_LEVEL(LogLevel::DEBUG);

Set the timestamp format (See conversion specifiers):

LOGGY_SET_TIMESTAMP_FORMAT("%Y-%m-%d %H:%M:%S");

Set the source info:

LOGGY_SET_SOURCE_INFO_FORMAT("%f:%l");

Specifier	Explanation
f	The file path of where the log is being executed
l	The line in the file where the log is being executed

Set the log format:

LOGGY_SET_LOG_FORMAT("%t [%l] %s: %m");

Specifier	Explanation
t	The timestamp
l	The log level
s	The source information
m	The log message

Logging using the default log level:

LOGGY_LOG("DEFAULT LEVEL");

Logging using a custom log level:

LOGGY_LOG("FATAL", LogLevel::FATAL);
