Command

Command tasks run subprocesses. The simplest way is to use quickie.command() decorator to define a task. The decorated function should return either a string of command and arguments in POSIX shell format, or a list of strings.

from quickie import command

@command
def command_from_string():
    return "my_command arg1 arg2"

@command
def command_from_list():
    return ["my_command", "arg1", "arg2"]

To create a command from a class, inherit from quickie.tasks.Command and replace the quickie.tasks.Command.get_cmd() method. Or, replace the quickie.tasks.Command.get_binary() and quickie.tasks.Command.get_args() methods.

For example the followings are all equivalent:

from quickie import Command

class SomeCommand(Command):
    def get_cmd(self):
        return "my_command arg1 arg2"  # or ["my_command", "arg1", "arg2"]

class SomeCommand(Command):
    def get_binary(self):
        return "my_command"

    def get_args(self):
        return "arg1 arg2"  # or ["arg1", "arg2"]
