Flask-Runner
A set of standard command line arguments for Flask applications built on top of Flask-Script.
Example code
In its simplest usage, an application can create and initialize a Runner object as follows:
from flask import Flask
from flask.ext.runner import Runner
app = Flask(__name__)
runner = Runner(app)
@app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
runner.run()
This application now has command line options that expose many of the configuration options that can be sent as arguments to app.run():
$ python hello.py --help
usage: hello.py [-h] [-t HOST] [-p PORT] [--threaded] [--processes PROCESSES]
[--passthrough-errors] [-d] [-r] [--noeval] [--extra FILE]
[--profile] [--profile-count COUNT]
[--profile-percent PERCENT] [--profile-regex REGEX]
[--profile-dir DIR] [--lint]
Runs the Flask development server i.e. app.run()
optional arguments:
-h, --help show this help message and exit
-t HOST, --host HOST
-p PORT, --port PORT
--threaded
--processes PROCESSES
--passthrough-errors
-d, --no-debug
-r, --no-reload
--noeval disable exception evaluation in the debugger
--reload-extra FILE additional file for the reloader to watch for changes
--profile run the profiler for each request
--profile-count COUNT
