application_settings - version 0.4.0

"You write the dataclasses to define parameters for configuration and settings, application_settings takes care of the logic."

What and why

Application_settings is a package for providing a python application or library with parameters for configuration and settings. It uses toml or json files that are parsed into dataclasses. This brings some benefits:

• Minimal work for the developer of the application / library
• Parameters are typed, which allows for improved static code analyses.
• IDEs will provide helpful hints and completion when using the parameters.
• More control over what happens when a file contains mistakes (by leveraging the power of pydantic).
• Possibility to specify defaults when no file is found or entries are missing, i.e., aim for "zeroconf".
• Configuration parameters are read-only (i.e., changed by editing the config file); we recommend (and support) the use of toml for this, which is a human-oriented, flexible, standardardized and not overly complex format.
• Settings parameters are read-write (i.e., mostly changed via the UI of the application); we recommend (and support) use json for this, an established standardized machine-oriented format.

Parsing is done once before or during first access and the resulting set of parameters is stored as a singleton.
