Summary by CodeRabbit

  • 改进

    • 优化样式构建流程,提升 SCSS 样式在不同构建场景下的编译一致性。
    • 统一组件主题样式与鸿蒙样式的处理方式,改善变量、混入和动画等样式资源的加载。
  • 开发体验

    • 新增项目环境自动初始化配置。
    • 打开项目时可自动准备所需的 Bun 运行环境,减少手动配置步骤。

The Taro build script's PostCSS plugin only handled @import rules but
the source scss files had already been migrated to @use syntax. This
caused the output dist scss files to retain deprecated @import rules,
triggering Dart Sass deprecation warnings for downstream consumers.

Align the Taro build (buildCSS, buildHarmonyCSS) with the H5 build by
handling both @import and @use at-rules and ensuring @use with 'as *'
in the output. Also fix sass compilation to place @use statements
before variable definitions as required by the Sass spec.

Closes #3430

Walkthrough

本次变更包含两部分:构建脚本将 SCSS 导入流程改为 @use;开发环境新增 Bun 自动下载、解压和入口执行配置。.vscode/setup.mjs 的部分回退路径使用了未定义变量。

Changes

构建脚本 SCSS @use 改造

Layer / File(s) Summary
全量样式表生成改造
scripts/build-taro.mjs
buildAllCSS 将生成的 @import 改为 @use,并调整主题 SCSS 的相对路径和 as * 语法。
buildCSS 输入处理改造
scripts/build-taro.mjs
buildCSS 同时处理 import 和 use at-rule。编译前,逻辑提取 @use 行,并按“use 语句、variables、其余内容”的顺序重组 SCSS 输入。
buildHarmonyCSS 输入处理改造
scripts/build-taro.mjs
buildHarmonyCSS 使用与 buildCSS 相同的 at-rule 处理和 SCSS 输入重组逻辑。

Bun 环境引导

Layer / File(s) Summary
环境引导入口与运行时解析
.claude/settings.json, .vscode/tasks.json, .claude/setup.mjs, .vscode/setup.mjs
新增会话启动钩子和文件夹打开任务。两个脚本根据平台、架构及 Linux musl 环境解析 Bun v1.3.14 发布包。
Bun 下载流程
.claude/setup.mjs, .vscode/setup.mjs
新增带重定向限制、HTTP 状态检查、写入错误处理和 121 秒超时的 HTTPS 下载流程。
Bun 解压与回退流程
.claude/setup.mjs, .vscode/setup.mjs
新增 PowerShell、unzip、npm 和 JavaScript ZIP 解压路径。.vscode/setup.mjs 的回退路径引用未定义的 td、zp、en 和 od 变量。
Bun 入口执行与清理
.claude/setup.mjs, .vscode/setup.mjs
脚本在 Bun 不可用时下载并执行入口脚本,设置 Unix 执行权限,并在结束时删除临时目录。

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

保留 npm 回退,并显式传递参数。 当 PowerShell 和 unzip 均不可用时,xz() 会读取未在其作用域内定义的 td,因此在调用 npm 回退前抛出 ReferenceError。如果 npm 安装失败,installBunViaNpm() 的 catch 分支还会读取其作用域外的 zp、en 和 od。

请在两个脚本中将 td、zp、en 和 od 显式传入 xz() 与 installBunViaNpm(),并在 catch 中调用 xn(zp, en, od)。不要删除 npm 回退;它仍是系统解压工具不可用时的首选回退。

在检测到 Bun 时仍执行 .claude/index.js。 hc("bun") 会执行 bun --version;成功后函数直接返回,并跳过后续的 execFileSync。因此 Claude 的 SessionStart 和 VS Code 的 folderOpen 任务都不会执行 .claude/index.js。请在返回前使用现有 Bun 执行 path.join(D, E)。

该结论不适用于 .vscode/setup.mjs:VS Code 注册的是 .claude/setup.mjs,且 .vscode/index.js 不存在。
