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.

inlineexplicit

Parameters

gopts	Shared Pointer to GOptions instance used for verbosity/debug lookup.
cname	Not used currently: can be class name or additional info of who's calling the log
lname	The logger name

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 173 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 78 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.

get_class_name()

std::string GLogger::get_class_name ( ) const

inline

Definition at line 180 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 131 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 109 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.
