是否可以将python @ click.option装饰器重复用于多个命令? [英] Is it possible to reuse python @click.option decorators for multiple commands?

问题描述

我有两个Python CLI工具，它们共享一组常用的click.options.目前，通用选项已重复:

I have two Python CLI tools which share a set of common click.options. At the moment, the common options are duplicated:

@click.command()
@click.option('--foo', is_flag=True)
@click.option('--bar', is_flag=True)
@click.option('--unique-flag-1', is_flag=True)
def command_one():
    pass

@click.command()
@click.option('--foo', is_flag=True)
@click.option('--bar', is_flag=True)
@click.option('--unique-flag-2', is_flag=True)
def command_two():
    pass

是否可以将通用选项提取到可以应用于每个功能的单个装饰器中?

Is it possible to extract the common options in to a single decorator that can be applied to each function?

推荐答案

您可以构建自己的装饰器来封装常用选项:

You can build your own decorator that encapsulates the common options:

def common_options(function):
    function = click.option('--unique-flag-1', is_flag=True)(function)
    function = click.option('--bar', is_flag=True)(function)
    function = click.option('--foo', is_flag=True)(function)
    return function

@click.command()
@common_options
def command():
    pass
