LogPerformance

A Python logging utility class that provides performance monitoring, error tracking, and colored console output with file logging capabilities.

Class Overview

LogPerformance is a singleton class that implements a comprehensive logging system with the following features:

• Colored console output
• File logging with timestamp-based filenames
• Performance monitoring for functions
• Error tracking
• Warning messages
• Custom log levels

Methods

__new__(cls, *args, **kwargs)

Singleton pattern implementation that ensures only one instance of the class exists.

__init__(self)

Initializes the logger with:

• Colored console output handler
• File logging handler (if enabled)
• Custom log level configuration
• Directory creation for log files

check_exists_directory(work_directory: str) -> bool

Static method that checks if a directory exists.

create_directory(cls, work_directory: str) -> None

Class method that creates a directory if it doesn't exist and logs the creation.

log_performance(self, func: Callable) -> Callable

Decorator that measures and logs the execution time of a function.

• Logs function name, arguments, and execution time
• Returns the function's result

log_error(self, func: Callable) -> Callable

Decorator that catches and logs exceptions in a function.

• Logs the function name and error message
• Re-raises the exception after logging

log_warning(self, func: Callable) -> Callable

Decorator that logs warnings for function execution.

• Logs function name, arguments, and execution time
• Returns the function's result

info(self, msg: str) -> None

Logs an informational message with a smile emoji prefix.

warning(self, msg: str) -> None

Logs a warning message.

error(self, msg: str) -> None

Logs an error message with an exclamation mark emoji prefix.

_append_log_message(self, msg: str, level: int) -> None

Private method that appends log messages with timestamp and level.

• Handles debug level filtering
• Stores the last log message

Usage Example

from logperformance import LogPerformance

log = LogPerformance()

@log.log_performance
def example_function(arg1, arg2):
    # Your code here
    pass

@log.log_error
def error_prone_function():
    # Your code here
    pass

# Log messages
log.info("This is an info message")
log.warning("This is a warning")
log.error("This is an error")

Configuration

The logger can be configured using environment variables:

• LOG_LEVEL: Set to "DEBUG" for debug level logging
• DEBUG_WRITE_FILE: Set to "True" to enable file logging (default)
