How to use

psiconfig supports json and toml configurations. (To use json replace TomlConfig with JsonConfig in the following code.)

Set up a module to handle configuration

1. Create a config module in your project:

"""Config for <project>."""
from psiconfig import TomlConfig
CONFIG_PATH = <path to config file>  # NB need not exist


DEFAULT_CONFIG = {
    # a dictionary of default items that will be used if no config file is found
}


def get_config() -> TomlConfig:
    return TomlConfig(path=CONFIG_PATH, defaults=DEFAULT_CONFIG)


def save_config(config: TomlConfig) -> TomlConfig | None:
    result = config.save()
    if result != config.STATUS_OK:
        return None
    config = TomlConfig(CONFIG_PATH)
    return config


config = get_config()

Accessing config in a module

If you want to access config in a module, then, if you want the config version at start up:

from config import config

or, if you want the latest saved version of config:

from config import get_config
...
    self.config = get_config()

Config properties and methods

config.config: a dict of items in the configuration

get_config(path): returns the config object

save_config(config): saves the config items

Updating config items

config.config[<item key>] = <item value>
