Overview

Highly Configurable

Commands and arguments are highly configurable yet provide good defaults to work well out of the box.

import sys
from powercli import Command

cmd = Command(
    # Windows-style flag prefixes
    prefix_short=None,
    prefix_long="/",

    # use other stream
    file=sys.stderr,
)

Object Oriented

Arguments are classes which can be instantiated dynamically and are not directly bound to a parser class.

from pathlib import Path
from powercli import Flag

cmd = Command()

flag = Flag(
    identifier="foo",
    short="f",
    values=[("PATH", Path)],
)
cmd.add_arg(flag)

# ... or use the shorthand ...

cmd.flag(
    identifier="foo",
    short="f",
    values=[("PATH", Path)]
)

Generate man pages

$ python3 -m powerdoc path/to/file.py --man
$ python3 -m powerdoc path/to/file.py --man | groff -T utf8 -man

Colored output

The built-in provided flags and commands make use of colored output respecting the user's preference.
