配置见 pyproject.toml:
- line-length=100:贴着现有代码定。若用默认的 88 会重排 122 行,
噪音淹没真正有价值的修复。
- 启用 E/W/F/I/UP/B/C4/SIM/RET/PERF/RUF;**不**启用 PTH。因为本项目的路径
多是"字符串身份"——要塞进 subprocess 命令行、写进 JSON 存档、打印给用户,
全换 pathlib 只是包一层再拆一层,换来 70 处纯风格改动。
- 忽略 RUF001/002/003:中文全角标点是正确写法,不是"歧义字符"。
- 忽略 PERF203:剩下两处都是"逐项容错"语义(逐个牧场存档要立刻上报失败、
收获全部要跳过失败地块)。把 try 提到循环外会毁掉"一项失败不影响其它项"
这个行为,是错的优化。
自动修复 358 项:Dict/List/Optional 换成 PEP 585/604 写法、导入排序、
失效的 noqa、空占位 f-string 等。
手工修复的(这些是真问题,不是风格偏好):
- B904 x9:except 中 raise 补异常链。刻意区分——网络/IO 失败用 from exc 保留
根因;参数解析失败用 from None,因为底层 ValueError 对玩家只是噪音。
- RUF012 x2:StateView 的 plots/animals 原本是**类级共享可变列表**,
改成在 __init__ 里初始化(apply({}) 会提前返回,所以必须显式摆好)。
- F841:TUI 里一个赋值后再没用过的死变量。
- SIM105 x11:try/except/pass 统一改成 contextlib.suppress。
- SIM115:日志句柄改用 with。Popen 已把 fd 复制给子进程,父进程可安全关闭。
- E501 x7:拆超长行;main.py 那处顺手提取变量,避免超长嵌套表达式。
- E741:把 l/r 改成 left_line/right_line。
- 其余:RUF046 / PERF401 / RET504 / RUF005 / UP031 / B007。
ruff format 重排 24 个文件。
验证:97 项测试全绿。

"""规则机器人玩家——"AI 也能玩"的最小可用示例。
|
||
|
||
它的意义不在于"内置了 AI",而在于证明一件事:
|
||
**服务器把状态和合法动作都摊开了,外面是谁在决策根本不重要。**
|
||
这个机器人做决策的方式是"给候选动作打分",而一个 LLM 做决策的方式是
|
||
"读同一份 ``/api/actions``,用语言模型选一个"。两者的接口调用序列一模一样。
|
||
|
||
所以:
|
||
|
||
* :meth:`RuleBot.choose` 里那段打分逻辑 = 可以整体替换成 LLM 的"策略函数";
|
||
* :meth:`RuleBot.step` 的执行路径 = LLM 将来要走的那条路(读动作 → 执行 → 看回执)。
|
||
|
||
它只依赖 :mod:`farm.client`,因此既能在本机跑,也能从别处连上服务器跑——
|
||
换个 ``--url`` 就是一个独立的外挂玩家。
