Detailed Description

Logging utility with plog initialization.

Provides simple logging initialization to a file in logs/ directory with rotating file appender. Uses a custom single-line formatter that produces records in the form: [YYYY-MM-DD HH:MM:SS.mmm] [LEVEL] [file.cpp:function:line] message

Usage in main(): init_logging("registration"); // Creates logs/registration.log PLOG_INFO << "Application started"; PLOG_DEBUG << "Debug information"; PLOG_ERROR << "An error occurred";

Function Documentation

init_logging()

void init_logging ( const std::string & app_name, plog::Severity severity = plog::debug )

inline

Initialize logging to file in logs/ directory.

Creates logs/ directory if it doesn't exist and initializes plog with a rolling file appender using CustomFormatter. Log file is named <app_name>.log.

Parameters

app_name	Base name for log file (without .log extension). Example: "registration" → logs/registration.log
severity	Minimum log level to record (default: plog::debug). Levels: plog::verbose, plog::debug, plog::info, plog::warning, plog::error, plog::fatal

Exceptions

std::runtime_error

if directory creation or file initialization fails.

After calling this function, use plog logging macros: PLOG_VERBOSE << "Very detailed message"; PLOG_DEBUG << "Debug info"; PLOG_INFO << "Info message"; PLOG_WARNING << "Warning"; PLOG_ERROR << "Error"; PLOG_FATAL << "Fatal error";

Each log record is written on its own line, formatted by CustomFormatter as: [YYYY-MM-DD HH:MM:SS.mmm] [LEVEL] [FILE:FUNC:LINE] message
