"""树脂驾驶舱布局提取器 —— issue #84（父 EPIC #13「树脂模板封装」子任务）。
|
|||
|
|
|
|||
|
|
把已交付的树脂驾驶舱布局资产（`dashboard/cockpit.resin.yaml`）**抽取为可复用
|
|||
|
|
模板**，并提供「点位字典回填」能力，验证内核复制不同行业时的零改动假设
|
|||
|
|
（对齐 PRD 5.5「⑤ 配置化驾驶舱」：换行业只替换驾驶舱布局资产，前端代码不动）。
|
|||
|
|
|
|||
|
|
核心抽象：**布局资产 ↔ 布局模板 ↔ 点位字典** 三者解耦——
|
|||
|
|
|
|||
|
|
- 具体布局资产（`cockpit.resin.yaml`）含**硬编码**的点位绑定
|
|||
|
|
（如 `bind: R-801.TEMP`）与 KPI 指标名（如 `metric: resin_exchange_capacity`）；
|
|||
|
|
- 布局模板把这些硬编码值**变量化**为占位符（`{device}.{point}` / `{metric}`），
|
|||
|
|
仅保留布局骨架（$schema / title / theme / widgets 几何位置 / widget 类型）；
|
|||
|
|
- 实例化时用**目标行业的点位字典**回填占位符，得到该行业的具体驾驶舱布局。
|
|||
|
|
|
|||
|
|
对外 API：
|
|||
|
|
|
|||
|
|
- `extract_template(layout_yaml) -> dict`
|
|||
|
|
从具体布局资产抽取通用模板（变量化硬编码点位/指标）。
|
|||
|
|
- `instantiate(template, point_dict) -> dict`
|
|||
|
|
用点位字典回填占位符，生成具体布局（`bind` 用 `device.point` 填回）。
|
|||
|
|
- `diff_layouts(layout_a, layout_b) -> LayoutDiff`
|
|||
|
|
布局差异比对（schema/title/theme/widgets 几何与绑定差异）。
|
|||
|
|
- `PointDict.from_csv(path)` / `PointDict.lookup(device, point)`
|
|||
|
|
点位字典加载与查询（CSV 9 列，对齐内核 schema）。
|
|||
|
|
|
|||
|
|
纯标准库实现（无 yaml 依赖）：YAML 子集用 `_parse_yaml_subset` 解析；
|
|||
|
|
与 `templates/ti-cl4/llm-scenarios/` 同款「dataclass + Enum + 类型注解 +
|
|||
|
|
中文 docstring 引 PRD/EPIC」范式。
