typed-configparser 1.0.1

A typed configparser

typed-configparser

typed-configparser is an extension of the standard configparser module with support for typed configurations using dataclasses. It leverages Python's type hints and dataclasses to provide a convenient way of parsing and validating configuration files.

Features

✓ Fully typed.
✓ Use dataclasses to parse the configuration file.
✓ Support for almost all python built-in data types - int, float, str, list, tuple, dict and complex data types using Union and Optional.
✓ Built on top of configparser, hence retains all functionalities of configparser.
✓ Support for optional values (optional values are automatically set to None if not provided).
✓ Smarter defaults (see below).

Installation

You can install typed_configparser using pip:

pip install typed_configparser

Usage

basic_example.py

import dataclasses
from typed_configparser import ConfigParser

@dataclasses.dataclass
class AppConfig:
    host: str
    port: int
    debug: bool

# Create an instance of Typed ConfigParser
config_parser = ConfigParser()
config_parser.read("conf.ini")

app_config = config_parser.parse_section(AppConfig, section_name='AppSection')

print(f"Host: {app_config.host}")
print(f"Port: {app_config.port}")
print(f"Debug Mode: {app_config.debug}")

conf.ini

[AppSection]
host = localhost
port = 8080
debug = True

optional_example.py

import typing
import dataclasses
from typed_configparser import ConfigParser

@dataclasses.dataclass
class AppConfig:
    host: str
    port: int
    debug: typing.Optional[bool]

config_parser = ConfigParser()
app_config = config_parser.parse_section(AppConfig, section_name='AppSection')

Check example directory for more examples.

Defaults

• configparser includes sensible defaults options which allows you to declare a [DEFAULT] section in the config file for fallback values.
• typed_configparser goes a step further and allows you to set a final level of defaults at dataclass level.
