Walkthrough

本次变更优化了 useAlign.ts 中对弹出层对齐点（points）在翻转（flip）调整时的处理方式。原先直接用硬编码数组赋值的方式被替换为对现有 points 数组的映射与转换，通过分割、反转和重新拼接字符串的方式实现点的翻转。该逻辑在上下、左右四种翻转场景中均做了相同调整，其他如偏移量计算、可见性检查等逻辑未发生变化。

代码翻转如兔跃，
points 映射巧手调。
昨日硬编码已不见，
今日通用更灵巧。
对齐精准无烦恼，
逻辑清晰心欢笑。

445-447: 优化了位置翻转逻辑，确保使用最新值

之前的实现中，对于 Bottom-to-Top 方向的翻转，可能使用了硬编码的数组来替换 nextAlignInfo.points，现在改为对现有数组的每个元素进行映射转换，能够正确保留并使用所有最新的点位信息。这种方法更加通用和健壮。

---

490-492: 保持一致的翻转逻辑实现

Top-to-Bottom 方向的翻转现在使用与其他方向一致的映射转换方法，确保了代码风格统一性，也使得翻转过程能正确反映所有当前的点位信息。

---

542-544: 水平方向翻转实现的改进

Right-to-Left 方向翻转现在使用与其他方向相同的映射处理方式，只是使用索引 1 来指示水平方向。这种一致性的改进有助于代码的可维护性，同时解决了原始问题。

---

587-589: 完成所有方向的翻转逻辑改进

Left-to-Right 方向的翻转实现也采用了相同的映射方法，保持了代码的一致性。所有四个方向的翻转现在都能正确地保留和使用最新的点位信息，修复了原先存在的问题。

---

445-589: 整体评价：解决了位置翻转时最新值未被使用的问题

这些改动统一了四个翻转场景（Bottom-to-Top、Top-to-Bottom、Right-to-Left、Left-to-Right）中对 nextAlignInfo.points 的处理方式。将原来的直接赋值方式改为对数组中每个元素进行转换的方式，确保了在位置翻转过程中能够正确使用和保留所有最新的点位信息。

这种实现更加健壮，能够处理更多的场景，尤其是当有自定义的点位配置时。代码风格也更加一致，提高了可维护性。

🪧 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.
