Handle help arg by itself the same as no args
When the 'flask' command is used with only the '--help' parameter, this
change will make sure to try and load the app before the help callback
is run. This was previously only being done when the 'flask' command was
used by itself. This meant when passing in '--help', any custom commands
were not getting shown in the help message. With this change, custom
commands will be included in the help message when running 'flask' on
the command line by itself or with the '--help' parameter.

Flask

Flask is a lightweight WSGI web application framework. It is designed to make getting started quick and easy, with the ability to scale up to complex applications. It began as a simple wrapper around Werkzeug and Jinja, and has become one of the most popular Python web application frameworks.

Flask offers suggestions, but doesn't enforce any dependencies or project layout. It is up to the developer to choose the tools and libraries they want to use. There are many extensions provided by the community that make adding new functionality easy.

A Simple Example

# save this as app.py
from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello, World!"
$ flask run
  * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
