configlite 0.1.0

Lightweight self-healing config manager

ConfigLite

A lightweight self-healing config handler.

Quickstart

Subclass from the base BaseConfig object and add your variables and defaults.

You can then set import this from wherever is needed and access properties.

Installation

git clone this repository, then use pip install . to install it in your current environment.

Usage

Creating a Config

Create a subclass of the base BaseConfig object, adding your parameters and their defaults.

For example:

from configlite import BaseConfig


class MyConfig(BaseConfig):
    value: int = 10
    name: str = "test"
    pi: float = 3.14

Access

To use your created config, there are two methods:

• "globally", where a single instance created.
• "locally", initialising the class where needed.

Global

To create a global config, set up the config as a parameter in the toplevel __init__.py:

CONFIG = MyConfig("./path/to/config.yaml")

Then in the rest of your code you may import this object:

from my_package import CONFIG

value = CONFIG.value

This is most useful if your code requires a single config file for everything.

Local

Or a local config, where you create an instance of your subclass wherever it is needed:

from my_package import MyConfig

config = MyConfig("./path/to/config.yaml")

value = config.value

This can be useful if you are juggling multiple different config files dynamically.

Paths

The BaseConfig object can take either a single path, or a list of paths.

If a list is passed, the config will search each one in order, using the last one in the list if none are found.

Path Lists

Lets say you create a config this way:

class Config(BaseConfig):
    ...

CONFIG = Config(
    paths=[
        "config.yaml",
        "~/.config/app/config.yaml",
    ]
)

In this case, Config will take these steps:

1. Search for config.yaml in the current working directory.
2. If not found, search for ~/.config/app/config.yaml.
3. If still no file exists, create a default config at ~/.config/app/config.yaml

If we get to step 3, but then create a new config at ./config.yaml, this will take priority over the one found at ~/.config/app/config.yaml.

Example

See usage.py for an example.
