P1-1 安装一旦收尾就再也装不了第二个版本(终态面板没有出口)
- 页面侧:`Download::from_snapshot` 把 **Done / Cancelled** 当结束(`InstallView::finished`),
面板让回列表 —— 装完一个版本可以直接选下一个继续装(图:r2-done / r2-done-next)。
不清 `Failed`:失败态带着用户要的东西(停在哪个文件 + 去日志页)。
- 面板加真出口:失败态「Open logs」(实心)+「Dismiss」(文本 → `Message::CancelInstall`,
host 侧对没在跑的任务是安全 no-op),修掉「失败后连重试都不可达」。
- 决策抽成纯函数 `install::panel_state()`(Hint / Ready / Install),`panel()` 只是它的画法,
于是「能不能再装」可以被单测钉死,不用开图形环境。
- 两条新测试**不走 MockBackend**(它从不发 `InstallProgress`,终态永远跑不到 ⇒ 假绿):
直接构造 `AppState` + `apply(CoreEvent::InstallProgress(..))`。
P2-1 分类 chip 在真 host 上是空控件
- `from_snapshot(state, category, catalog)` 收分类并按 `Category::matches` **本地过滤**
(真 host 的 `ListVersions(_)` 丢掉分类参数、回全量清单);
- 分类不再从列表反推(`Category::of` 只留给演示首帧),`app/view.rs::model` 收分类、
`refresh_view` 把上一份视图模型的分类带回去 ⇒ 事件回来 chip 不会跳回「全部」;
- `update.rs` 的 `SetCategory` 写分类后**立刻重建**(chip 与列表同一个谓词),再派真指令。
p3(顺带)
- 失败态与占位态共存:列表空/加载中时若安装还在跑,面板照样出现在底部(r2-installing-empty);
- 修 `install.rs` 的坏 rustdoc 链接;`install.rs` / `model.rs` 的测试模块外置到子文件守住 400 行。
测试文件:`pages/download/{model,install}/tests.rs`(新),`pages/download/tests.rs` 里的
`from_snapshot` 调用补分类参数。
实证(回退法):删掉 `.filter(|view| !view.finished())` → 两条终态测试红并点名
「Done 之后不许再占着安装面板」;删掉 `.filter(|category.matches(..))` → 两条分类测试红
(「只剩正式版」left=3 right=1)。放回修复 → 全绿。
门禁:fmt --check 干净、clippy -D warnings 干净、app-iced 280 + 集成 6 + i18n 23 全绿(-j 4)。

//! 消息目录:`Key` 枚举 + 中英两套常量表 + 取词 / 占位符渲染 / 缺译诊断。
|
||
//!
|
||
//! ## 为什么 key 是枚举而不是字符串
|
||
//!
|
||
//! 字符串 key(`"nav.instances"`)拼错了编译器一声不响,运行时才知道——本仓的说法是「运行时静默回落」。
|
||
//! 枚举 key 把这类错误前移到**编译期**:`Key::NavInstance`(真名是 `NavInstances`)直接
|
||
//! `error[E0599]`,不可能跑到运行时。
|
||
//!
|
||
//! **这里没有守卫测试**:曾经写过一个 `compile_fail` 文档测试想守这条,但复审实测它对
|
||
//! 「把 `Key` 换成字符串包装类型」这类变异仍然全绿——它守的是「这段代码编译不过」,而不是
|
||
//! 「编译期校验还在」。说不清真假的守卫比没有更糟,所以删了;这条纪律只靠枚举这个事实本身。
|
||
//!
|
||
//! ## 为什么两套译文写在**同一行**
|
||
//!
|
||
//! ```ignore
|
||
//! NavInstances => ("Instances", "实例"),
|
||
//! ```
|
||
//!
|
||
//! 一行就是「一个 key 的全部语言」。于是「加了 key 忘了译文」在结构上不可能发生——这比「运行时发现
|
||
//! 缺译再诊断」更强。缺译诊断([`Catalog::diagnose`])因此有两个真实用途:
|
||
//!
|
||
//! 1. **注入目录**:后续 mission 用 [`Catalog::from_entries`] 加第三套(繁体 / 更多语言)时,
|
||
//! 表格是手写的,缺条目的风险回来了;
|
||
//! 2. **回归守门**:万一有人把这张表改回「两套各写一遍」,[`Catalog::missing`] 的守卫测试立刻红。
|
||
//!
|
||
//! ## 缺译时给什么
|
||
//!
|
||
//! **不回落**(绝不拿另一种语言顶替,用户会看到「一半英文一半中文」的界面而不自知):
|
||
//!
|
||
//! - [`Catalog::get`] → `None`(严格调用方用它);
|
||
//! - [`Catalog::text`] → [`MISSING`](`⟪missing⟫`,UI 上刺眼但一眼可辨);
|
||
//! - [`Catalog::render`] → `⟪missing:KeyName⟫`(带上 key 名,方便照着日志补译)。
