ten-utils 0.0.15

A python library that implements many small tools that are often used in python development.

🧰 ten-utils

A Python toolkit with commonly used development utilities: logging, in-memory buffers, env variable loading, and more — designed to reduce boilerplate and accelerate development.

---

✨ Features

• ✅ Structured logging with file support(at the time of version 0.0.14 the file saving functionality has not yet been implemented)
• ✅ Memory-based buffer system
• ✅ Env file loading with type validation
• 🛠️ More utilities coming soon...

📦 Installation

You can install ten-utils using pip:

pip install ten-utils

Or with development tools:

pip install ten-utils[dev]

---

🚀 Quick Start

So far, the library has a few utilities like this:

• log - Utility for logging any actions in the code. The tool implements the main class Logger and the class for configuration of the main class LoggerConfig.
• buffer - A utility that creates a value inside the program memory and stores it until it is disabled or intentionally deleted by the user using a method.
• env_loader - A utility for loading and validating environment variables using a .env file.

Quick start for log utility

from ten_utils.log.logger import Logger
from ten_utils.log.config import LoggerConfig


# Set global configuration
LoggerConfig().set_default_level_log(1)       # Set minimum level to INFO
LoggerConfig().set_save_log_to_file(False)    # Don't write to file

# Create logger instance
logger = Logger(__name__)  # or any other logger name

# Logging
logger.debug("This is a debug message")     # Will be ignored (default = INFO)
logger.info("App started successfully")
logger.warning("This is a warning")
logger.error("An error occurred")

You can also change the configuration at any time within the code. A new instance of the Logger class will use the new configuration you set, while an old instance of the Logger class will use the old configuration.

from ten_utils.log.logger import Logger
from ten_utils.log.config import LoggerConfig


LoggerConfig().set_default_level_log(1)       # Set minimum level to INFO
LoggerConfig().set_save_log_to_file(False)    # Don't write to file

# Create logger instance
logger = Logger(__name__)

# Logging
logger.debug("This is a debug message")     # Will be ignored (default = INFO)
logger.info("App started successfully")
logger.warning("This is a warning")
logger.error("An error occurred")

# Installing a new configuration
LoggerConfig().set_default_level_log(2)       # Set minimum level to WARNING
LoggerConfig().set_save_log_to_file(True)     # Enable file output

# Creating a new instance
logger1 = Logger(__name__)

# Logging
logger1.debug("This is a debug message 1")     # Will be ignored (default = WARNING)
logger1.info("App started successfully 1")     # Will be ignored (default = WARNING)
logger1.warning("This is a warning 1")
logger1.error("An error occurred 1")

Warning:

• Logs will not be saved to a file, because at the time of v0.0.14 this is not yet implemented.

It's also worth talking about the logger.critical methods:

from ten_utils.log.logger import Logger
from ten_utils.log.config import LoggerConfig


LoggerConfig().set_default_level_log(4)     # Set minimum level to CRITICAL

logger = Logger(__name__)

logger.critical("Critical log!")

There is an important point that when logger.critical is triggered, the programme crashes with the message: Process finished with exit code 1. This behaviour occurs because logger.critical executes exit(1) at the end of execution.

Quick start for buffer utility

from ten_utils.buffer import Buffer


buffer = Buffer()

# Set a value named 'Test' with a value of 'True'.
buffer.set("Test", True)

# Getting value from buffer
value = buffer.get("Test")
print(value)

# Clearing the entire buffer
buffer.clear()

Info:

• The Buffer class is implemented using the metaclass Singleton. Therefore an instance of the Buffer class can be initialised once and used throughout the programme

Quick start for env_loader utility

from ten_utils.env_loader import EnvLoader

# Create instance and load .env file
env_loader = EnvLoader(".env")

# Reading environment variables
db_name = env_loader.load("DB_NAME", str)
port = env_loader.load("PORT", int)
is_active = env_loader.load("IS_ACTIVE", bool)
allowed_hosts = env_loader.load("ALLOWED_HOSTS", list)

print(db_name, port, is_active, allowed_hosts)

Example .env file:

DB_NAME=mydatabase
PORT=5432
IS_ACTIVE=true
ALLOWED_HOSTS=localhost,127.0.0.1,example.com
