Example Code

from pathlib import Path
from typing import Annotated
import sys

import typer
from typer import Context, Typer

app = Typer(no_args_is_help=True)

@app.callback()
def common(
    path: Annotated[Path | None, typer.Option(
        "--path",
        "-p",
    )] = None
):
    pass


subcommand = Typer()

def autocomplete(args: list[str]):
    print(args, file=sys.stderr)
    return ["abc", "def"]

@subcommand.command(name="command")
def command(ctx: Context, abc: Annotated[str, typer.Argument(autocompletion=autocomplete)] = "abc"):
    pass

app.add_typer(subcommand, name="subcommand")

Description

I have some completions that depends on the params passed to the root command callback.
I am not able to get these arguments or the get the raw command string, so I can't get the "path" value is the autocomplete() function here.

args for me is always []

How should I do ?

Operating System Details

MacOS 26.0.1

Typer Version

Additional Context

Here is a pyproject to reproduce:

[project]
name = "typer_raw"
version = "0.0.1"
dependencies = ["typer"]

[project.scripts]
cli = "typer_raw:app"

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

File name is named typer_raw.py and is right next to the pyproject.toml.
I used uv sync, then activated the .venv and then used cli --install-completion

I'm using ZSH 5.9 arm64-apple-darwin25.0

Given you actually want the parameter as Path, not as raw string, have you tried using the (parent) context to access it?

def autocomplete(ctx: Context):
    print(ctx.parent.params.get("path"), file=sys.stderr)
