    #MoonClip

    MoonClip 是用 MoonBit 实现的二维多边形几何库，提供整数与统一十进制网格的小数入口。0.2 系列提供整数／小数 Boolean、偏移与描边的孔洞层级输出。运行库不依赖 C++ 或其他几何运行时。

    版本内容见 CHANGELOG，下载、校验和及验收摘要见 GitHub Release v0.2.0。0.2.0 发布记录区分发布源码、注册表安装和后续状态提交；0.1.0 历史记录保持原样，成果说明保留来源、贡献和申报边界。

    #从 Mooncakes 使用

    在自己的 MoonBit 模块中运行：

    moon add BigSaltyMan/moonclip@0.2.1

    在包的 moon.pkg 中导入 BigSaltyMan/moonclip，配置见下文。0.2.0 已完成独立 native／JS 注册表消费者验证；0.2.1 只修正文档，运行库与公开接口保持一致。数值与预算边界按 scope.md 解释。

    #0.1.0 已有、0.2.0 继续提供的能力

    用途公开入口成功结果
    区域布尔boolean_op / boolean_op_d整数 / 小数平铺轮廓
    孔洞层级boolean_tree整数 PolyTree64
    闭合区域偏移offset_polygons / offset_polygons_d整数 / 小数平铺轮廓
    开放路线加宽stroke_polyline / stroke_polyline_d整数 / 小数多边形区域
    显式简化simplify_paths / simplify_paths_d轮廓、删点数及三类退化索引
    单图案扫掠minkowski_sum整数平铺轮廓

    Boolean 支持 Intersection、Union、Difference（Subject 减 Clip）、Xor，以及公开 EvenOdd / NonZero；Positive / Negative 仍是内部能力。Offset 和 Stroke 支持 Miter、Bevel、Square、Round 四种连接；Stroke 提供 Butt、Square、Round 三种端点。方向、边界框、精确两倍有向面积、点包含及无损重复点整理也已实现。完整接口见 pkg.generated.mbti，入口默认值与限制见 支持范围。

    #0.2.0 新增树接口

    下列增量已随 0.2.0 正式发布，并完成 registry 来源的独立 native／JS 消费者验证。新增库入口共 5 个：小数 Boolean 树与整数／小数偏移树、描边树；整数 boolean_tree 已在首版提供。0.2 系列均提供这些入口，0.1.0 不包含这些增量。完整发布事实见 0.2.0 记录。

    只需要结果边界可继续使用平铺入口；需要孔洞归属则直接调用对应树入口；已有树可用 to_paths() 取得独立轮廓副本，但会丢失显式层级。完整迁移路径见树接口升级说明，历史 CI、测试口径与六入口候选消费者见增量验收材料。

    stroke_tree(path, width, cap=, options=, limits=) 返回 Result[PolyTree64, ClipError]，stroke_tree_d(path, width, precision=, cap=, options=, limits=) 返回 Result[PolyTreeD, ClipError]。width 是完整宽度，默认 Butt，支持三种端点和四种连接。输入是一条开放路线，返回清理后填充区域的层级；首尾重合仍保留开放端点语义。输入整理、生成、清理、树构建和解码共用预算。两个描边树入口均未随 0.1.0 发布，示例见 组合说明。

    offset_tree(paths, delta, fill_rule=, options=, limits=) 返回 Result[PolyTree64, ClipError]；offset_tree_d(paths, delta, precision=, fill_rule=, options=, limits=) 返回 Result[PolyTreeD, ClipError]。默认 NonZero，沿用四种连接与现有偏移参数。树表达最终偏移区域，扩张、收缩可能合并区域、分裂轮廓或消灭孔洞。规范化、生成、清理、树构建及小数解码共用一份累计预算。两个偏移树入口均未随 Mooncakes 0.1.0 发布。示例见 组合说明。

    boolean_tree_d(subject, clip, operation, precision=, fill_rule=, limits=) 返回 Result[PolyTreeD, ClipError]，默认 Precision=3、EvenOdd。PolyTreeD 提供 roots() / to_paths()；节点提供 contour() / children() / depth() / is_hole()，访问器数组均独立复制。

    该入口已随 0.2.0 发布，Mooncakes 0.1.0 不包含此接口。层级沿用量化后整数区域已验证的拓扑，Precision 变化可能影响可表达关系；坐标解码为 Double，to_paths() 会丢失显式父子关系。用法及预算见 小数树说明，可运行的完整断言见下文 CLI 示例。当前源码接口见 .mbti；首版 0.1.0 的接口范围仍按历史记录解释。

    #数据与使用边界

    • Point64 保存不可变的完整 Int64；Path64 / Paths64 是有序可变数组。几何运算的每轴范围为 ±1,000,000,000，包含边界。存储范围与运算范围不同。
    • 构造原样保存空路径、单点、两点及重复点；闭合轮廓通常不重复存储首点，由算法解释闭合边。结构比较严格保留坐标、长度和顺序。
    • 数组赋值可以共享存储。需要隔离时用 copy_path / copy_paths（小数有 _d 版本）；集合复制同时隔离内外数组和输入别名。
    • Precision::new 支持 0—6，默认 3。小数公开调用先检查并量化到十进制网格，再执行整数核心；范围随精度缩小。量化可能报合并或退化错误，不能把它当成任意精度浮点几何。
    • 计算入口返回 Result，失败不修改输入、不发布部分结果。默认原始输入预算为 10,000 条路径、100,000 个点；内部另有累计节点和工作预算，合法坐标及数量不保证复杂输入一定完成。
    • simplify_paths 需要显式调用，不保证拓扑保持。面积为零不能直接判断自交输入没有区域；point_in_polygon 仅解释单轮廓 EvenOdd。

    数值、舍入、错误和预算详见 numerics.md、decimal.md、composition.md。孔洞方向、简化报告、扫掠闭合语义及尚未提供的能力集中列在 scope.md。

    #从本地源码运行

    使用 固定工具链。Windows 使用 Git Bash；Linux 使用 Bash：

    git clone https://github.com/BigSaltyMan/moonclip.git
cd moonclip
moon run --target native cmd/example

    cmd/example/main.mbt 是受检的公开调用示例，包含复制隔离、精确几何、Boolean / PolyTree、带孔偏移、路线描边、小数组合、显式简化和图案扫掠。它检查完整轮廓与错误，成功输出：

    Decimal tree: outer/hole/island OK
Simplify vertices: 9 -> 8; input_degenerate=[2]; degenerate=[2]; collapsed=[]; offset/tree OK
Minkowski: rectangle/polyline, offcenter/diagonal and closed route/hole OK
MoonClip geometry, Boolean, PolyTree, offset, stroke, composition, decimal, simplify and Minkowski OK

    该包的 moon.pkg 导入根模块 BigSaltyMan/moonclip。0.2.0 包内示例检查小数树、偏移树及描边树；0.1.0 的旧示例和注册表消费者仍按该版本接口解释。

    导入配置与随包示例相同（cmd/example/moon.pkg）：

    import {
      "BigSaltyMan/moonclip",
    }

    pkgtype(kind: "executable")

    包导入配置与 cmd/example/main.mbt 是受检的使用起点，各类 API 按上表进入 scope.md。发布 ZIP 包含运行库、接口、该示例和文字文档；演示、测试、参考工具与基准从 Git 仓库使用。scripts/check_release.py 只审计源码候选及解压消费者，不执行发布；0.2.0 的真实注册表安装验证见 发布记录。

    #浏览器交互演示

    cd demo
npm run dev

    打开 http://127.0.0.1:4173。区域 Boolean、带孔偏移、路线加宽三个场景可切换整数 / 小数及 Precision；路线页签另有仅整数的图案扫掠。显式简化默认关闭，出现退化时显示报告并停止后续计算。计算调用 MoonBit 核心，JS 处理交互、绘制和下载。

    演示无 npm 依赖，无需先安装包。在 demo 目录运行 npm test 复用已构建产物做 20 项桥接／导出冒烟；npm run build 生成可静态托管的 demo/dist，npm run build -- --reuse 可只打包已有产物。SVG 独立打开并保留孔洞；JSON 保存原输入、参数、精度、真实结果及简化统计。输入变更或错误会禁用导出。

    0.2.0 源码的演示提供孔洞层级查看：Boolean、Offset、Stroke 的整数／小数六个树入口可展开父子节点、选择边界高亮；SVG 仍只导出填充区域，树 JSON 使用版本 2 保存层级与可复现请求。平铺模式默认行为和版本 1 JSON 保持兼容，Minkowski 只支持平铺。

    操作说明见 demo.md，三张主要场景截图及实际操作记录见 浏览器验收。

    #检查与性能基线

    bash scripts/check.sh
bash scripts/bench.sh --target native --report _build/bench/report.json

    统一检查执行格式、接口、native / JS 回归、构建、CLI 示例和离线参考工具；普通 CI 另构建演示、执行桥接冒烟及一个极小基准入口。修改代码后运行 moon info && moon fmt 并审查接口变化。

    已发布 0.1.0 的正确性基线为同一批 2234 项库测试。0.2.0 相对首版累计新增 89 项树定向测试（小数 Boolean 33、偏移 27、描边 29），当前源码完整回归计数为 2323；演示的 20 项桥接测试独立统计，native、JS 分别执行，不相加。1384 条独立参考案例对应 2276 项能力检查，旧数据未改，也不宣称覆盖新增入口。固定种子只覆盖公开 Boolean 平铺结果。覆盖矩阵及既有执行证据见 兼容报告，失败缩减见 随机回归说明。

    native release 的 11 个固定基准（含三个有上限的压力探针）已测量，环境、输入输出规模、中位数及最小 / 最大值见 性能基线。没有测上游速度，不作跨库性能结论；CI 不设耗时阈值。

    fn orientation(a : Point64, b : Point64, c : Point64, limits? : Limits) -> Result[Orientation, ClipError]

    Mathematical axes: x right, y up; positive cross is counterclockwise.

    point_in_polygon

    source
    fn point_in_polygon(point : Point64, path : Array[Point64], limits? : Limits) -> Result[PointLocation, ClipError]

    Single closed contour, EvenOdd rule. Half-open y intervals count a shared vertex once; horizontal edges participate only in the boundary check.

    point_on_segment

    source
    fn point_on_segment(point : Point64, a : Point64, b : Point64, limits? : Limits) -> Result[Bool, ClipError]

    simplify_paths

    source
    fn simplify_paths(paths : Array[Array[Point64]], options? : SimplifyOptions, limits? : Limits) -> Result[SimplifyResult, ClipError]

    simplify_paths_d

    source
    fn simplify_paths_d(paths : Array[Array[PointD]], precision? : Precision, options? : SimplifyOptions, limits? : Limits) -> Result[SimplifyResultD, ClipError]

    stroke_polyline

    source
    fn stroke_polyline(path : Array[Point64], width : Double, cap? : CapType, options? : OffsetOptions, limits? : Limits) -> Result[Array[Array[Point64]], ClipError]

    Stroke a single open route with full width, two sides at width / 2. Width below 1 and routes with fewer than two effective points produce no area.

    stroke_polyline_d

    source
    fn stroke_polyline_d(path : Array[PointD], width : Double, precision? : Precision, cap? : CapType, options? : OffsetOptions, limits? : Limits) -> Result[Array[Array[PointD]], ClipError]

    stroke_tree

    source
    fn stroke_tree(path : Array[Point64], width : Double, cap? : CapType, options? : OffsetOptions, limits? : Limits) -> Result[PolyTree64, ClipError]

    Final filled hierarchy of a single open route. Introduced in 0.2.0.

    stroke_tree_d

    source
    fn stroke_tree_d(path : Array[PointD], width : Double, precision? : Precision, cap? : CapType, options? : OffsetOptions, limits? : Limits) -> Result[PolyTreeD, ClipError]

    Open-route stroke hierarchy on the decimal grid. Introduced in 0.2.0.

    validate_paths

    source
    fn validate_paths(paths : Array[Array[Point64]], limits? : Limits) -> Result[Unit, ClipError]

    Validate raw inputs without copying or normalizing them.
