Your new jeeves-super-plugin

• Create a Python 3.10+ virtual env for your new plugin project
• pip install -U pip poetry
• poetry init
• poetry add jeeves-shell --extras=all
• Write into pyproject.toml:

[tool.poetry.plugins.jeeves]
super-plugin = "jeeves_super_plugin:app"

• Create your Typer instance:

jeeves_super_plugin/__init__.py

import typer

app = typer.Typer(no_args_is_help=True)

@app.command()
def hi(name: str):
    """Greet the user."""

@app.command()
def bye():
    """Bid farewell."""

• poetry install
• j super-plugin

You should see hi and bye as available commands.

Special plugin name: __root__

[tool.poetry.plugins.jeeves]
__root__ = "jeeves_super_plugin:app"

This will mean that your plugin replaces the default root Jeeves app, and your commands will be available as

• j hi instead of j super-plugin hi
• j bye instead of j super-plugin bye.

This is useful for plugins like jeeves-yeti-pyproject, to make the commands you very often use, like lint, faster to type.
