写第一版 EPRO2 → .kicad_sch 转换：把 SCH_PAGE Document 的 wires +
COMPONENT placements + TEXT 输出到一个可被 KiCad 7+ 打开的 sch 文件。
不含 symbol 主体（lib_symbols 留空 stub），所以 KiCad 里组件会渲染
成红色 "?" 占位，但布线 + 位置 + Designator/Value 属性都正确。完整
symbol 库导出留 Phase 2。
模块结构：
tools/epro2/kicad/sexpr.py 手写 S-expr emitter，Sym 标记裸符号，
str 自动加引号 + 转义；float 去尾零；
bool→yes/no；NaN/Inf 主动报错
tools/epro2/kicad/_sexpr_reader.py 极简 S-expr parser，仅给 round-trip
测试用（非完整 KiCad reader）
tools/epro2/kicad/sch_writer.py write_sch_page(doc) → str；处理：
LINE → (wire (pts ...) ...)
COMPONENT → (symbol (lib_id facere:<partId>)
(at x y rot) (property Reference ...) ...)
TEXT → (text "..." (at ...))
单位 mil → mm × 0.0254；零长 wire 跳过
tools/epro2/kicad/__main__.py CLI: --doc <uuid> | --all-sch
ESP-VoCat 验证（python -m tools.epro2.kicad <project> --all-sch）：
9 SCH_PAGE 全部转换成功

codec_0b0163fa.kicad_sch wires=190 symbols=112 text= 10
输出落在 data/processed/kicad_sch/<filename>.kicad_sch（gitignore 内，
可重新生成；不入库）。
测试：6 个 sexpr 测 + 6 个 sch_writer 测，含 round-trip parse 验证。
parser/relations/project_relations 的旧 21 个不动，合计 **33/33 通过**。
下一步：
1. Phase 2 — symbol library 导出 (.kicad_sym)，把 SYMBOL doc 的 PIN/RECT/
TEXT primitives 转 KiCad symbol 主体；填 lib_symbols 块让组件渲染
出真正的 schematic 符号
2. footprint library + .kicad_pcb 导出
3. 用 KiCad CLI (kicad-cli sch erc) 跑 ERC 校验

"""KiCad export from EPRO2.
|
|
|
|
Phase 1 (current): schematic only — paper, wires, junctions, symbol placements
|
|
without symbol bodies. Output is a single .kicad_sch file
|
|
that KiCad will open (showing wires + placeholders for
|
|
missing symbols).
|
|
|
|
Phase 2 (planned): symbol library export (.kicad_sym) from SYMBOL docs;
|
|
wire it via lib_symbols block in the .kicad_sch.
|
|
|
|
Phase 3 (planned): footprint library + .kicad_pcb generation.
|
|
|
|
Coordinates: EasyEDA schematic stream stores in **mil** internally; KiCad uses
|
|
mm. Conversion factor ``MIL_TO_MM = 0.0254`` is applied at writer level.
