CLI lets user choose between health check and decision analyzer

[jmelburg]

supersedes #395
resolves #465

the streamlit import error is due to it not being included in the core dependencies. You have to run this:

uvx 'pdstools[app]'

If this is acceptable I think it now all works as expected, though I can't properly test it with uvx before we publish a new version.
For now I was testing with:

uv tool install -e '.[app]'
uvx pdstools

I'm not sure uvx pdstools can work out of the box without making streamlit a core dependency.

@jmelburg thanks :)

I think we could perhaps solve this by adding the optional dependencies in app to the dependencies list? Something like this

# /// script
# requires-python = ">=3.9"
# dependencies = [
#     "pdstools[app]>=4.0.3",
#     "streamlit"
# ]
# ///

uv should pick it up. https://docs.astral.sh/uv/guides/scripts/

I wonder if we just need streamlit or other things too?

uv picks it up, uvx does not

there are some vaguely related issues (astral-sh/uv#6542) at uv raised already, but nothing indicating this will become possible. I see two options now:

1. use uv run pdstools and declare the app dependency group as dependency in the cli.py script header
   • Straightforward
   • Does not work globally
2. use uvx 'pdstools[app]'
   • Works globally
   • Slightly annoying syntax

If we really want option 3 uvx pdstools I can raise another issue

Pretty sure we could make both of these work at the same time, right?

Let's document these two in the documentation and call it a day :)

[jmelburg]

Found a middle ground solution:

uv tool install 'pdstools[app]'

ensures pdstools is callable from anywhere and prompts you to choose between health check and decision analyzer. When run, it prompts you to choose between the Health Check and Decision Analyzer. The tool is installed in an isolated environment, avoiding the global dependency conflicts often caused by pip. We have updated the docs to make this the recommended quickstart installation.

@StijnKas could you review and publish if it's all okay?
