Detailed Description

GLogger manages output messages categorized as debug, info, warning, error, and critical. It allows conditional printing based on verbosity and debug flags, supports colored output, and automatically adds a counter to each message.

Parameters

gopts	Pointer to GOptions instance used for verbosity/debug lookup.
name	The verbosity or debyg name is a string used to identify the logger and as header for all messages

Member Function Documentation

critical()

template<typename... Args>

void GLogger::critical ( Args &&...  args ) const

inline

Template Parameters

Args	Variadic template parameters for any streamable types.

Parameters

args	Message parts to be logged.

Definition at line 162 of file glogger.h.

debug()

template<typename... Args>

void GLogger::debug ( debug_type  type, Args &&...  args  ) const

inline

Uses variadic templates with perfect forwarding and fold expressions to construct the log message.

Template Parameters

Args	Variadic template parameters representing any streamable types.

Parameters

type	The debug message type (NORMAL, CONSTRUCTOR, or DESTRUCTOR).
args	The message components.

This method uses:

• Variadic templates to accept any number of arguments.
• Perfect forwarding with std::forward to preserve value categories.
• Fold expressions to stream all arguments into an ostringstream.

Definition at line 68 of file glogger.h.

error()

template<typename... Args>

void GLogger::error ( int  exit_code, Args &&...  args  ) const

inline

Template Parameters

Args	Variadic template parameters for any streamable types.

Parameters

exit_code	The program exit code.
args	Message parts to be logged before exiting.

Note

This function is marked [[noreturn]] because it always terminates the process.

Definition at line 148 of file glogger.h.

info() [1/2]

template<typename... Args>

void GLogger::info ( Args &&...  args ) const

inline

Template Parameters

Args	Variadic template parameters for any streamable types.

Parameters

args	Streamable message components.

Definition at line 119 of file glogger.h.

info() [2/2]

template<typename... Args>

void GLogger::info ( int  level, Args &&...  args  ) const

inline

Template Parameters

Args	Variadic template parameters for any streamable types.

Parameters

level	The importance level (0 = always, 1 = only if verbosity > 0, 2 = more detailed).
args	Message components to log.

If an invalid verbosity level is requested, logs an error and exits.

Definition at line 97 of file glogger.h.

warning()

template<typename... Args>

void GLogger::warning ( Args &&...  args ) const

inline

Template Parameters

Args	Variadic template parameters for any streamable types.

Parameters

args	Message parts to be logged.

Always prints regardless of verbosity or debug levels.
