Easy utils for creating a script runner

Project description


clue_script is used for defining subcommands with a special focus on web-style apps. The functionality is inspired by the Django script.


  • Python 2.6 or 2.7 (not tested with Python 3.x)

runserver support (optional)

  • Paste
  • argparse (if deploying on Python < 2.7)


A simple example to add a command that prints “hello world”:

from clue_script import command, Commander

def helloworld():
    print 'hello world'

if __name__ == '__main__':

To do a more complicated command you can use something similar to Python 2.7’s argparse (also available on 2.6).

import argparse
from clue_script import command, Commander

def foo(*argv):
    parser = argparse.ArgumentParser()
    parser.add_argument('-x', help='simple test',
                        default='yes', metavar='x')
    ns = parser.parse_args(argv)
    # do something

if __name__ == '__main__':

Provided Commands

There are currently two provided command factories.

  1. make_reloadable_server_command (see above note about requirements for runserver)
  2. make_syncdb_command

A typical web app could use these commands as follows:

if __name__ == '__main__':
    def createtables(session):

    settings = init_settings()
    commander = script.Commander([script.make_reloadable_server_command(make_app),

Running the script with no args will yield something similar to:

    runserver     Run a reloadable development web server.
    syncdb        Update the database.
