Pythonclickmodule is used to create command-line (CLI) applications. It is an easy-to-use alternative to the standard optparse and argparse modules. It allows arbitrary nesting of commands, automatic help page generation, and supports lazy loading of subcommands at runtime. Theclickmodule was cr...

"" click.echo(f'Hello, {name}!') if __name__ == '__main__': hello() 在上面的例子中,@click.command()装饰器定义了一个命令,@click.option()则定义了一个可选参数--name,如果用户没有提供该参数,会通过prompt属性提示用户输入。 3.2.2 自定义类型转换与验证 Click允许开发者自定义参数类型,并...

就算用了更高级一点的Click,也需要不停的写option, 而且有几个option对应函数就要写几个输入参数与之匹配,写代码实在是繁琐,比如以下Click代码: import click from caesar_encryption import encrypt @click.command() @click.argument('text', nargs=-1) ...
Example usage: @click.command()@click.argument('files',nargs=-1,type=click.Path())deftouch(files):forfilenameinfiles:click.echo(filename) And from the command line: $ touch -- -foo.txt bar.txt -foo.txt bar.txt
@cli.command()@click.pass_context defsync(ctx):click.echo('Debug is %s'%(ctx.obj['DEBUG']and'on'or'off'))if__name__=='__main__':cli(obj={}) 在上面的示例中: 通过为命令组cli和子命令sync指定装饰器click.pass_context,两个函数的第一个参数都是ctx上下文 ...
click.echo('Debug mode is %s' % ('on' if debug else 'off')) @cli.command() # @cli, not @click! def sync(): click.echo('Syncing') 1. 2. 3. 4. 5. 6. 7. 8. 执行效果如下: Usage: tool.py [OPTIONS] COMMAND [ARGS]... ...
Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It's the "Command Line Interface Creation Kit". It's highly configurable but comes with sensible defaults out of the box. ...
