How to work with defaults?

[Zentheon]

I happened to find this project after realizing implementing something similar myself was a bit more involved than I wanted, and it seems like a really novel, neat way to do it!

Experimenting around for a bit, I've started to realize I'm either not doing it right or something else is going on. An example:

# respackr/generate/main.py

from argparsedecorator.annotations import Exactly1, Option
from termaconfig import ConfigValidationError, TermaConfig
from terminaltables3 import DoubleTable

from respackr import cli


@cli.command()
def generate(config_path: Option | Exactly1[str] = ["respackr.toml"]):
    """Generates zipped resourcepacks, ready to publish or use in-game"""

    spec_path = "respackr/spec.toml"

    global config

    try:
        config = TermaConfig(config_path[0], spec_path, tabletype=DoubleTable, logging=False)
    except ConfigValidationError:
        print()
        print("Errors are present in configuration. Exiting...")
        exit()

    print("Testing config:", config["pack"])

Expression of type "list[str]" cannot be assigned to parameter of type "Option | Exactly1[str]" is what Pyright returns for that particular annotation, though as far as I can see from the docs, that's how it should be done. Also, Exactly1 returns a list when the arg is specified, but if the default is a simple string (not one-item list) it returns a string too. I guess it makes sense for consistency with the more than one ExactlyX options, though, pyright also complains about "__getitem__" method not defined on type "Exactly1[str]" in that case as well.

Another semantics issue is that the intended way to use argparseDecorator seems to be to recursively import, which makes type checkers complain quite a bit. For the annotation classes, there are two different import paths between annotations and parsernode, assuming the former is technically more correct. I imaging it's inconsequential where they're imported from, but it seems like it should be a bit more resolute what's correct there?
