Breaking Changes

  • 🔥 Remove auto naming of groups added via add_typer based on the group's callback function name. PR #1052 by @patrick91.

Before, it was supported to infer the name of a command group from the callback function name in the sub-app, so, in this code: 

import typer

app = typer.Typer()
users_app = typer.Typer()

app.add_typer(users_app)


@users_app.callback()
def users():  # <-- This was the inferred command group name
    """
    Manage users in the app.
    """


@users_app.command()
def create(name: str):
    print(f"Creating user: {name}")

...the command group would be named users, based on the name of the function def users().

Now you need to set it explicitly: 

import typer

app = typer.Typer()
users_app = typer.Typer()

app.add_typer(users_app, name="users")  # <-- Explicitly set the command group name


@users_app.callback()
def users():
    """
    Manage users in the app.
    """


@users_app.command()
def create(name: str):
    print(f"Creating user: {name}")

Updated docs SubCommand Name and Help.

Note: this change will enable important features in the next release. 🤩
