Hi @aantn, can you provide the links to previous discussions, to have the full context? Thanks!

Sure.

• [QUESTION] How to wrap commands #296
• [QUESTION] How do I share options or arguments between commands? #153
• Need feature to share options or arguments between commands #405

The solution that is closest to what I want is #296 (comment) but I'd like to improve on the syntax by adding native support.

I recently found https://github.com/greendwin/typer_di which seems to meet my requirements. I am still evaluating, but if typer_di works well, I will close this.
