Managers
Managers can be used together by merging them
from third_party import manager
my_app_manager.merge(manager)
# Merge within a new namespace:
my_app_manager.merge(manager, namespace='third_party')Commands
Commands can be organized within namespaces
@manager.command(namespace='config')
def set(key, value):
# ...Arguments
Currently the framework will assume that arguments with default values are key-value arguments (--arg value) while required arguments are positional ones.
In other words, this definition:
@manager.command
def create(user):
passwill expect an invocation of the kind:
$ manage create foobar
and user in create() will take the value 'foobar'.
On the other hand, this:
@manager.command
def create(user=''):
passwill expect an invocation of the kind:
$ manage create --user foobar
The downside is obviously that it’s not currently possible to have a required non-positional argument.
Argument definition can be overridden
@manager.arg('first_arg', help='this is help for first arg')
@manager.command
def my_command(first_arg):
# ...Arguments can be prompted
@manager.prompt('password', hidden=True, confirm=True)
@manager.command
def connect(username, password):
# ...Environment
Environment variables can be sourced from a .env file as key=value pair.
Environment variable can be enforce using Manager.env decorator
@manager.env('MY_ENV_VAR')
@manager.command
def my_command():
return os.environ['MY_ENV_VAR']Release history Release notifications | RSS feed
