Added

Added

- Added a GitHub action for PyPi deployment
- Check for presence of the dataclass decorator
(Issue [76](https://github.com/StockwatchDev/application_settings/issues/76))
- Enable file inclusion for toml config files
(Issue [67](https://github.com/StockwatchDev/application_settings/issues/67))
- Added logging
(Issue [17](https://github.com/StockwatchDev/application_settings/issues/17))
- Added a recipe for handling configurable initialization of module global variables
and class variables

Changed

- pydantic.dataclasses.dataclass and pydantic.ValidationError now exported from our
namespace (Issue [36](https://github.com/StockwatchDev/application_settings/issues/36))
- Exceptions added to docstrings (Issue
[16](https://github.com/StockwatchDev/application_settings/issues/16))
- Upgraded pydantic to version 2.0, which has a different way of doing type conversion,
see the [conversion table](https://docs.pydantic.dev/2.0/usage/conversion_table/)
(Issue [75](https://github.com/StockwatchDev/application_settings/issues/75))

Added

- Multiple versions of documentation served on Github Pages.
- You can now request a (re-) load when setting the filepath or via a method `load`.
- You can choose whether or not to throw a `FileNotFoundError` during `load`
when the parameter file is not found in the expected location
(Issue [51](https://github.com/StockwatchDev/application_settings/issues/51))
- Support for parameters in the main container (Issue
[20](https://github.com/StockwatchDev/application_settings/issues/20)).
- Support for subsections (arbitrary depth) (Issue
[5](https://github.com/StockwatchDev/application_settings/issues/5)).
- Sections also stored as a singleton, so that libs can define and access parameters
via their own Section (Issue
[46](https://github.com/StockwatchDev/application_settings/issues/46)).
- Literal SectionTypeStr exported.
- Convenience functions to specify filepath for config and settings via command-line
[[53](https://github.com/StockwatchDev/application_settings/issues/53)]

Changed

- The method `update` now is a class method (breaking).
- You cannot request a reload via method `get` anymore, use separate method `load`
(breaking).
- A Container now is a specialization of a ContainerSection.

Fixed

- Default folder name no longer just a dot if container class is called Config or
Settings.

Added

- Files can be formatted as `toml` or `json`.
- Introduced settings, i.e., read-write parameters (where config is read-only).
- Now also useable with python 3.9.
- Documentation extended and served on Github Pages.

Changed

- File path for config / settings now via `set_filepath()` and no longer as argument of
`get()`.

Added

- Loading a `toml` file.
- Initializing a dataclass with the loaded toml and storing it as a singleton.
- Default path, folder and file name.
- Specification of a config file path via argument of `get()`.
- Validation using pydantic.
- README that explains it all.
