Detailed Description

Logger utilities for deltaFlow, providing logging macros and a singleton Logger class.

This file declares the logging macros and the Logger class for handling logging at various severity levels. The logger supports logging to a file and console with different levels: NOTSET, DEBUG, INFO, WARN, ERROR, CRITICAL.

Macros (e.g., DEBUG, INFO) simplify use throughout the codebase.

Macro Definition Documentation

LOG_CRITICAL

#define LOG_CRITICAL	(		msg,
			...
	)		Logger::getLogger().log(fmt::format(FMT_STRING(msg), ##__VA_ARGS__), Level::CRITICAL)

Macro for logging a critical-level message.

Definition at line 89 of file Logger.H.

LOG_DEBUG

#define LOG_DEBUG	(		msg,
			...
	)		Logger::getLogger().log(fmt::format(FMT_STRING(msg), ##__VA_ARGS__), Level::DEBUG)

Macro for logging a debug-level message.

Definition at line 85 of file Logger.H.

LOG_ERROR

#define LOG_ERROR	(		msg,
			...
	)		Logger::getLogger().log(fmt::format(FMT_STRING(msg), ##__VA_ARGS__), Level::ERROR)

Macro for logging an error-level message.

Definition at line 88 of file Logger.H.

LOG_INFO

#define LOG_INFO	(		msg,
			...
	)		Logger::getLogger().log(fmt::format(FMT_STRING(msg), ##__VA_ARGS__), Level::INFO)

Macro for logging an info-level message.

Definition at line 86 of file Logger.H.

LOG_MESSAGE

#define LOG_MESSAGE	(		msg,
			...
	)		fmt::print("{}\n", fmt::format(FMT_STRING(msg), ##__VA_ARGS__))

Macro for printing messages to stdout.

All macros use fmt formatting and forward the formatted message to the logger.

Definition at line 90 of file Logger.H.

LOG_WARN

#define LOG_WARN	(		msg,
			...
	)		Logger::getLogger().log(fmt::format(FMT_STRING(msg), ##__VA_ARGS__), Level::WARN)

Macro for logging a warning-level message.

Definition at line 87 of file Logger.H.
