Walkthrough

本次变更主要优化了 useIndicator 钩子的状态更新逻辑，通过对比新旧样式对象中各属性的值，仅在实际发生变化时才触发状态更新，避免因浮点数微小差异造成的不必要重渲染。同时，依赖项 activeTabOffset 的监听方式从对象引用改为字符串化内容，确保仅在内容变化时重新执行 effect。测试方面，扩展了 Tabs 组件关于 indicator 属性的用例，覆盖了小数宽度、指示器对齐方式动态变更、RTL 模式下的样式等边界场景。此外，删除了项目根目录下的 vercel.json 配置文件。

Changes

文件/文件组	变更摘要
src/hooks/useIndicator.ts	优化 ink bar 样式状态更新逻辑，避免因浮点误差导致的重复渲染，调整 effect 依赖项的判断方式。
tests/index.test.tsx	增加 Tabs 组件指示器相关的测试用例，覆盖小数宽度、动态对齐、RTL 场景等。
vercel.json	删除 Vercel 部署配置文件，移除静态构建相关设置。

代码轻盈如兔跃，
指示器宽度不再抖。
浮点微差不扰梦，
对齐切换样样有。
测试加严护质量，
代码春风拂耳柔。

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

615-628: 完善了指示器小数值处理和防抖动的测试用例

这些测试用例很好地覆盖了指示器组件在处理小数值和防抖动方面的行为：

1. 测试小数值的处理（例如 origin - 0.5）确保小数宽度能正确应用
2. 测试防抖动功能验证了微小差异（0.1 与 0.2）不会导致不必要的样式更新

这些测试对应了 useIndicator.ts 中的优化改动，确保修复能正确工作。

671-681: 添加了指示器动态对齐切换的测试

这个测试很好地验证了当 align 属性从 'start' 动态变更为 'center' 时，指示器位置能够正确更新。使用 rerenderStart 进行动态渲染测试是一个很好的方法。

---

717-741: 完善了垂直布局和 RTL 模式下的指示器测试

这些测试用例很好地覆盖了边界场景：

1. 测试在垂直布局（tabPosition="left"）下动态切换 align 属性的行为
2. 测试 RTL（右到左）模式下指示器的样式表现

验证 transform 样式包含 translateY(-50%) 确保了 RTL 模式下垂直居中能正确工作。
