💄 Add option for panels to fit to content

[harkabeeparolus]

Provide an option for using Rich Panel.fit() aka Panel(expand=False) for help panels and errors. This was mentioned in discussion #607 and #680. To opt into this new, non-default behavior, just use:

app = typer.Typer(rich_expand=False)

I think this can look nicer on very wide terminals, especially for CLIs with few parameters, or short parameter descriptions, so I would prefer to have the option to choose this style sometimes.

Status

• The code worked fine on all the examples I tried from the Typer tutorial
• The documentation I added is perhaps a little sparse.
  • I don't know yet how to capture command output for the Typer docs, and I think an example is needed. Help?
• I'm not sure how to write tests for this. Suggestions are welcome!

Any chances to merge this PR soon? Can someone please restart CI?

Any chances to merge this PR soon?

I believe what's missing is test coverage for my new code and logic, which is not my strong suit. I would appreciate any help or suggestions on how to approach writing tests for this.

I updated the PR to remove merge conflicts, and:

• Fixed a bug.
• Added rich_expand to typer.run() for convenience. 😊

Remaining issues:

• I still need help with test coverage. 😬 I'm not familiar enough with the codebase to understand what's going on.
  • I have manually tested this code on many of the code samples in the Typer documentation, and some of my own code, with no issues so far.
  • As far as I can tell, the only failing CI tests right now are on 3.8 and 3.9, which are end of life. Should we address these? 🤨
• I have updated the text of the documentation, but I haven't made any screenshots, because I don't know what procedure you use to make them consistent with the rest of the docs.
