- folder 模式从「按第一级目录分段」改为当前目录视图:子目录在前(带子树书数), 直接书在后;进入/返回只过滤已扫平的 g_books,不 readdir、不重扫(M32 索引不动)。 - 纯函数 shelf_build_rows_at(books,n,folder,cwd,...) + nav 工具(enter/up/breadcrumb/ count)全部宿主可测;format 模式行序列/副题逐字不变,path 仍是完整路径(进度键不变)。 - 交互:点目录进入;顶栏返回箭头/左缘返回手势回上一级,根层再返回退出 App;顶栏标题= 当前目录名(按像素宽截断),副题行=面包屑全路径+当前层书数;list/grid 均支持导航。 - 状态:folder↔format、list↔grid 切换保留 cwd;刷新重扫后 cwd 失效则收缩到有书的祖先。 - 边界:空目录不显示(导航只读 g_books,不额外 readdir);深层目录逐级进入;真实名为 「未分类」的目录按普通目录处理,不与根层书合并。 - 测试:shelf_group_smoke 63→99 断言;M27 的按第一级分组断言改写为「逐级进入后可见该书」 (同等强度),新增进入/返回/面包屑/计数/空目录/纯内存/rowcap/UTF-8 截断断言。 - 交付 0.1.7/code8(M32 已占用任务书里的 0.1.6/code7);真机 0.1.4 未被覆盖。

/* app/shelf.c — 书架:扫 TF 卡 `Books/`,识别 TXT/FB2/EPUB/MOBI/CBZ(R1 仅 TXT 可开,
|
||
* 其它显示「R2 支持」占位);MD3 布局(meow_topappbar + list/grid)+ 最近阅读置顶 + 段头分组。
|
||
*
|
||
* 布局(README §3.2,用户 2026-09-04 拍板):
|
||
* - 默认 list(meow_listview_set_container(on) MD3 圆角卡;**行数 > SHELF_ROUND_MAX_ROWS
|
||
* 时自动降级为扁平行**——圆角卡逐像素填充太慢,见 shelf_build_content 注释),
|
||
* 可切 grid(meow_lazygrid 4 列封面卡);布局存 reader.conf `ui.shelf_layout`;
|
||
* - 顶栏 meow_topappbar:标题「书架」+ 动作(布局切换 / 分组切换 / 刷新 / App 设置入口);
|
||
* - 无书也渲染完整骨架(顶栏 + 内容区 + 居中空态卡 + 指引 + 支持格式);
|
||
* - 封面:MVP 无封面提取(engine F1);无则圆角占位(surfaceContainerHigh + 格式徽标)。
|
||
*
|
||
* M27 分组(`ui.shelf_group`,默认 format 保持旧行为):
|
||
* format = 按格式分段(TXT/FB2/EPUB/MOBI/CBZ),与改动前完全一致;
|
||
* folder = **目录导航**(M33):书架只显示当前目录(cwd)的内容——子目录在前(带子树书数)、
|
||
* 直接属于该层的书在后;点目录进入、点书打开;左缘返回/顶栏返回箭头回上一级,
|
||
* 到 Books 根再返回才退出 App。行序列在 app/shelf_model.c(纯 C,宿主可测);
|
||
* 本文件只维护 cwd 并做控件装配/绘制。导航只过滤已扫平的 g_books,不重扫/不 readdir。
|
||
* M33 状态:folder↔format 切换与 list↔grid 切换都**保留 cwd**(切回 folder 还在原目录);
|
||
* 顶栏「刷新」重扫后若 cwd 已不存在(目录/书被删),收缩到最近的仍有书的祖先。
|
||
*
|
||
* M29 性能(用户反馈「几百本书首页卡得飞起」):
|
||
* - **扫描结果进程内缓存**:只在本进程首次进入书架时扫 Books/;从阅读页返回不再重扫
|
||
* (真机 exFAT 全量扫描 3.1s,是「回书架冻结」的唯一大头)。顶栏「刷新」强制重扫。
|
||
* 行为变化:新放进 Books/ 的书需点一次「刷新」才出现。
|
||
* - **行数多时关圆角容器**(见 SHELF_ROUND_MAX_ROWS):圆角卡逐像素填充,595 本时滑一步 46ms。
|
||
* M30:M29 的「刚读完不置顶」缺口补上(只刷一本书的 ts + 内存重排,不重扫全盘)。
|
||
* M31:置顶时一并重算这本的副题(shelf_fmt_sub),「· 读」立即出现,不等下一次全量刷新;
|
||
* 顶栏「刷新」同时丢弃字体路径缓存(新拷入的字库此时生效)。
|
||
* M32:书架索引落盘(app/shelf_index.c)。冷启动先试 `MeowData/os.meow.reader/index/shelf.idx`:
|
||
* 版本、CRC、root 路径、**Books 根 + 一级目录** 的 mtime 校验通过 → 直接出书,**完全跳过 readdir**。
|
||
* 真机冷缓存实测 434 个目录逐个 stat 要 3.15s(与 readdir 同量级),所以只校验
|
||
* 根 + 一级目录(4 次 stat ≈20ms);代价是 level-2 及更深处的变更不会自动失效,
|
||
* 需点「刷新」(与 M29「新书靠刷新」同一约定)。任何异常 → 照常全量重扫(fail-open)。
|
||
* 扫描完成后原子写回索引(写失败只丢缓存,不影响书架)。
|
||
* M29 语义不变:首次进书架=索引或全扫;从阅读页返回=不扫;顶栏「刷新」=清索引+全扫。
