Wrapper

mylib/wrapper

• cwebp

AttrName

its attribute is a str same as the name thereof

实例的属性总是一个和属性名称相同的字符串

from ezpykit import AttrName

an = AttrName()
assert an.abc_xyz == 'abc_xyz'
an.abc_xyz = 123456  # nothing happens

ArgumentParserRigger

use argparse in @decorator style

通过装饰器来使用argparse

features:

• full decorating style for adding arguments or sub-commands;
• user-defined mapping from arguments to parameters (of the decorated function);
• the decorated function remains untouched;
• thus the decorated function can be re-used anywhere as though it was never argparse-decorated;
• the rigger knows which function is to be called and how to call it.

# test.py

from ezpykit.stdlib.argparse import *

apr = ArgumentParserWrapper()
an = apr.an  # an.abc_xyz == 'abc_xyz'
an.x = an.y = an.z = an.l = ''  # let the IDE remember these attr names


@apr.sub(lambda x: x.replace('_', '-'))  # xyz_and_more -> xyz-and-more
@apr.arg(an.x)
@apr.arg(an.y)
@apr.arg(an.z)
# flag means option with action='store_true', so the flag 'l' means option '-l'
@apr.flag(an.l, help='print in multiple lines')
# arg x -> param x, int(1111) -> param y, arg z -> param z, extra -> param y, flag -l -> param multi_line
@apr.map(an.x, apr.obj(1111), an.z, apr.toe, multi_line=an.l)
def xyz_and_more(x, y, z, more, multi_line=False):
    print(f'x={x}', f'y={y}', f'z={z}', f'and more: {", ".join(more)}', sep='\n' if multi_line else ', ')


@apr.sub()
@apr.arg('a')
@apr.arg('b')
@apr.map('a', 'b')
def ab(a, b):
    print(a, b)


apr.parse(catch_unknown_args=True)
apr.run()
