[QUESTION] How to implement global options.

[shmokmt]

First check

• I used the GitHub search to find a similar issue and didn't find it.
• I searched the Typer documentation, with the integrated search.
• I already searched in Google "How to X in Typer" and didn't find any information.
• I already searched in Google "How to X in Click" and didn't find any information.

Description

How can I implement global options like --install-completion, --show-completion?

Click allows to easily implement global options in context.
I want a simple function similar to typer.

Additional context

I often implement global options such as --env and --debug.

By inspecting the code it seems like this is not possible right now.
How do we imagine such API?

I'd be tempted to say like in click with a group decorator, so as to stay in familiar territory :)

I tried various stuff with the add_typer command without being able to achieve the desired result.
That would be awesome to get an answer.

This is the main blocker identified for us so far switching from click as we make quite a fair use of global switches, most often for logging

I imagine this as an option in the app ie Typer instances, that way it'd work even without subcommands

Thanks for the discussion here everyone!

Here are the new docs for using is_eager: https://typer.tiangolo.com/tutorial/options/version/ 🎉

And here for adding global CLI options: https://typer.tiangolo.com/tutorial/commands/callback/ 🚀
