Example Code

import click
import typer

def validate_name_typer(ctx: typer.Context, param: typer.CallbackParam, value: str) -> str:
    params = ctx.command.params # Autocompletion and syntax highlighting don't work
    return value

def validate_name_click(ctx: click.Context, param: typer.CallbackParam, value: str) -> str:
    params = ctx.command.params # Autocompletion and syntax highlighting work
    return value

def main(name: str= typer.Option(...,callback=validate_name_typer)):
    typer.echo(f"Hello {name}")


if __name__ == "__main__":
    typer.run(main)

Description

On VSCode, I don't have autocompletion for the context in a callback. I am not sure where it comes from but this definitely seems a typer issue since it is working with Click.

I added both in the example.

EDIT: I am here trying to get other options from this callback.

having a similar weird issue where autocompletion is working fine in bash/osx, but in pwsh/win11 some of my autocomplete works, but others fail in the same script.

For example using def hi(name: List[str] = typer.Argument(..., autocompletion=something)): ... works fine to suggest completions starting from empty name or partial string, but if I drop the List and do def hi(name: str = typer.Argument(..., autocompletion=something)): ... then I get autocomplete suggestions if I [tab][tab] from an empty argument, but as soon as I have one or more characters incomplete string then [tab][tab] gives nothing and apparently my callback something isn't even called.

Tried various combinations of typer/click version but can't find a clue yet.

btw in your example you're using autocompletion rather than callback for typer?
