moke 1.1.9

Moke transforms a Python module into a command line script. Every function can become a sub-command, with options inferred from the argument list and the optional doc string.

A command line application that greets exactly two persons. (put the following into a file called mokefile.py:

from moke import task, log

@task
def greet(who, shout=False, times=1):
    """
    Sends greetings from moke.

     - who(str2) two persons to greet
     - shout(switch) triggers CAPS

    """
    greetings = ("Hello %s and %s!" % (who[0], who[1])) * times
    if shout:
        greetings = greetings.upper()
    print greetings
    log("greeted: %s and %s" % (who[0], who[1]), INFO)

if __name__ == "main":
    task()

Execute the mokefile by calling moke:

moke greet --shout -times 2 Mary Kate

this returns:

2011-09-30 14:12:52,815 moke (version 1.0.0)
2011-09-30 14:12:52,815 cwd: "/home/.../moke/test/scripts"
2011-09-30 14:12:52,815 mokefile: "/home/.../moke/test/scripts/mokefile.py"
2011-09-30 14:12:52,815 task: greet
2011-09-30 14:12:52,815 params: ('who', ['Mary', 'Kate']) ('shout', True) ('times', 2)
HELLO MARY AND KATE!
HELLO MARY AND KATE!

If you forgot what your mokefile.py does, just ask for help:

moke --help

usage: mokefile.py [-h] [-ls LS] [-ll {info,warn,error}] [-lf {tab}]
  {greet} ...

positional arguments:
  {greet}
    greet               Sends greetings from moke.

optional arguments:
  -h, --help            show this help message and exit
  -ls LS                (file_a) [default: <stderr>] logging stream
  -ll {info,warn,error}
                        (str) [default: info] logging level
  -lf {tab}             (str) [default: tab] logging format

Sub-command specific help is also generated:

moke greet --help

usage: mokefile.py greet [-h] [--shout] [-times TIMES] who who

positional arguments:
  who           (str) two persons to greet

optional arguments:
  -h, --help    show this help message and exit
  --shout       (switch) triggers CAPS
  -times TIMES  (int) [default: 1]

Now it’s time to start your own Mokefile:

moke new [filename]

Which creates a skeleton file for you:

$ moke new Mokefile
moke: *** Created /...path.../Mokefile
moke: *** Running 'moke Mokefile --help'

Have fun!
