:说明:
支持 ``shell_like`` 解析参数的命令形式匹配,根据配置里提供的 ``command_start``, ``command_sep`` 判断消息是否为命令。
可以通过 ``state["_prefix"]["command"]`` 获取匹配成功的命令(例:``("test",)``),通过 ``state["_prefix"]["raw_command"]`` 获取匹配成功的原始命令文本(例:``"/test"``)。
添加 ``shell_like_argpsarser`` 参数后, 可以自动处理消息并将结果保存在 ``state["args"]`` 中。
:参数:
* ``shell_like_argsparser: Optional[ArgumentParser]``: ``argparse.ArgumentParser`` 对象, 是一个类 ``shell`` 的 ``argsparser``
* ``*cmds: Union[str, Tuple[str, ...]]``: 命令内容
:示例:
使用默认 ``command_start``, ``command_sep`` 配置
命令 ``("test",)`` 可以匹配:``/test`` 开头的消息
命令 ``("test", "sub")`` 可以匹配”``/test.sub`` 开头的消息
当 ``shell_like_argsparser`` 的 ``argument`` 为 ``-a`` 时且 ``action`` 为 ``store_true`` ``state["args"]["a"]`` 将会记录 ``True``
\:\:\:tip 提示
命令内容与后续消息间无需空格!
