more-click 0.0.4

More click.

more_click

Extra stuff for click I use in basically every repo

More Options

The module more_click.options has several options (pre-defined instances of click.option()) that I use often. First, verbose_option makes it easy to adjust the logger of your package using -v.

There are also several that are useful for web stuff, including

Name	Type	Flag
more_click.host_option	str	--host
more_click.port_option	str	--port

Web Tools

In many packages, I've included a Flask web application in wsgi.py. I usually use the following form inside cli.py file to import the web application and keep it insulated from other package-related usages:

# cli.py
import click
from more_click import host_option, port_option


@click.command()
@host_option
@port_option
def web(host: str, port: str):
    from .wsgi import app  # modify to point to your module-level flask.Flask instance
    app.run(host=host, port=port)


if __name__ == '__main__':
    web()

However, sometimes I want to make it possible to run via gunicorn from the CLI, so I would use the following extensions to automatically determine if it should be run with Flask's development server or gunicorn.

# cli.py
import click
from more_click import host_option, port_option, with_gunicorn_option, workers_option, run_app


@click.command()
@host_option
@port_option
@with_gunicorn_option
@workers_option
def web(host: str, port: str, with_gunicorn: bool, workers: int):
    from .wsgi import app  # modify to point to your module-level flask.Flask instance
    run_app(app=app, with_gunicorn=with_gunicorn, host=host, port=port, workers=workers)


if __name__ == '__main__':
    web()

For ultimate lazy mode, I've written a wrapper around the second:

# cli.py
from more_click import make_web_command

web = make_web_command('my_package_name.wsgi:app')

if __name__ == '__main__':
    web()

This uses a standard wsgi-style string to locate the app, since you don't want to be eagerly importing the app in your CLI since it might rely on optional dependencies like Flask. If your CLI has other stuff, you can include the web command in a group like:

# cli.py
import click
from more_click import make_web_command


@click.group()
def main():
    """My awesome CLI."""


make_web_command('my_package_name.wsgi:app', group=main)

if __name__ == '__main__':
    main()
