# AI Code Diff Preview
|
||
|
||
> 类 Cursor 的 AI 代码差异预览 VSCode 插件
|
||
|
||
[](https://github.com/YonHaoGuo/ai-diff-preview/blob/master/CHANGELOG.md)
|

|
||

|
||
|
||
AI Code Diff Preview 为 VSCode 注入 Cursor 风格的 Accept/Reject 差异审查体验。AI 对话中的每一次代码编辑自动收集，对话结束后弹出完整的变更文件列表。点击任意文件即可在 **VSCode 内置 Diff 编辑器**中逐文件审查，状态栏实时显示 Accept/Reject 按钮，操作完成后自动推进到下一个待处理文件。
|
||
|
||
## 特性
|
||
|
||
- **VSCode 原生 Diff 编辑器** — 使用 `vscode.diff` 命令，100% 原生交互体验，无自定义 Webview
|
||
- **EditRecord 独立追踪** — 每次 `Edit`/`Write` 操作作为独立编辑记录，支持逐次编辑 Accept/Reject
|
||
- **QuickPick 总览** — 对话结束后弹出原生文件列表，含 Accept All / Reject All 一键操作
|
||
- **智能 Auto-Advance** — Accept/Reject 后自动推进到下一个待处理文件，同文件多编辑自动停留
|
||
- **状态栏常驻** — 插件激活后状态栏始终可见 `$(diff) AI Diff`，有变更时黄底高亮
|
||
- **零保存提示** — Diff 编辑器使用临时文件，关闭时自动删除，不会弹出"是否保存"对话框
|
||
- **多轮对话追踪** — 支持同一轮对话中对同文件的多次编辑合并、跨轮对话的独立追踪
|
||
|
||
## 安装
|
||
|
||
### 方式 A：直接安装 .vsix 文件（推荐）
|
||
|
||
1. 从 [Releases](https://github.com/YonHaoGuo/ai-diff-preview/releases) 下载最新 `ai-diff-preview-*.vsix`
|
||
2. VSCode 中 `Ctrl+Shift+P` → **Extensions: Install from VSIX** → 选择下载的文件
|
||
3. 重启 VSCode
|
||
|
||
### 方式 B：源码编译安装
|
||
|
||
```bash
|
||
git clone https://github.com/YonHaoGuo/ai-diff-preview.git
|
||
cd ai-diff-preview
|
||
npm install
|
||
npm run build
|
||
npm run package # 生成 ai-diff-preview-*.vsix
|
||
# 然后按方式 A 的第2步安装
|
||
```
|
||

|
||
|
||
## ⚠️ 必须配置：启用 Claude Code Hooks
|
||
|
||
**插件依赖 Claude Code 的 Hooks 机制才能工作，安装后必须配置，否则不会触发！**
|
||
|
||
打开 Claude Code 配置文件（**任选其一**）：
|
||
|
||
| 作用范围 | 配置文件路径 |
|
||
|----------|-------------|
|
||
| **当前项目**（推荐） | 项目根目录 `.claude/settings.json` |
|
||
| **所有项目** | Windows: `C:\Users\<用户名>\.claude\settings.json`<br>macOS/Linux: `~/.claude/settings.json` |
|
||
|
||
将以下内容**合并**到你已有的配置文件中（`hooks` 是顶层字段，和现有字段平级）：
|
||
|
||
```json
|
||
{
|
||
"hooks": {
|
||
"PostToolUse": [
|
||
{
|
||
"matcher": "tool_name === 'Edit' || tool_name === 'Write'",
|
||
"hooks": [
|
||
{
|
||
"type": "command",
|
||
"command": "node -e \"const fs=require('fs');const p=process.cwd()+'/.claude/hooks/pending.json';try{fs.mkdirSync(require('path').dirname(p),{recursive:true});fs.writeFileSync(p,JSON.stringify({toolName:process.env.CLAUDE_TOOL_NAME,filePath:process.env.CLAUDE_TOOL_INPUT_FILE_PATH,oldString:process.env.CLAUDE_TOOL_INPUT_OLD_STRING||'',newString:process.env.CLAUDE_TOOL_INPUT_NEW_STRING||'',content:process.env.CLAUDE_TOOL_INPUT_CONTENT||'',timestamp:Date.now(),type:'edit'}));}catch(e){console.error(e)}\""
|
||
}
|
||
]
|
||
}
|
||
],
|
||
"Stop": [
|
||
{
|
||
"hooks": [
|
||
{
|
||
"type": "command",
|
||
"command": "node -e \"const fs=require('fs');const p=process.cwd()+'/.claude/hooks/pending.json';try{fs.mkdirSync(require('path').dirname(p),{recursive:true});fs.writeFileSync(p,JSON.stringify({toolName:'Stop',filePath:'',oldString:'',newString:'',content:'',timestamp:Date.now(),type:'stop'}));}catch(e){console.error(e)}\""
|
||
}
|
||
]
|
||
}
|
||
]
|
||
}
|
||
}
|
||
```
|
||
|
||
配置完成后，**重启 Claude Code 对话**即可生效。
|
||
|
||
## 使用方法
|
||
|
||
### 快速开始
|
||
|
||
1. **安装插件** → 重启 VSCode → 状态栏左侧出现 `$(diff) AI Diff`
|
||
2. **用 Claude Code / Cursor 对话** → 每次 Edit/Write **自动静默收集**，不打断工作流
|
||
3. **对话结束 (Stop)** → 自动弹出 **QuickPick 总览**，列出所有变更文件
|
||
4. **↑↓ 键选择文件** → 回车打开 **VSCode 内置 Diff 编辑器**，左侧原始代码、右侧变更后
|
||
5. **查看状态栏右侧** → 三个彩色按钮：`✓ Accept` `✗ Reject` `✓✓ 接受此文件全部`
|
||
6. **点击 Accept / Reject** → 变更立即应用到磁盘 → **自动推进**到下一个文件
|
||
7. **全部处理完** → 🎉 通知，状态栏回到常态
|
||
|
||
### 一键操作速查
|
||
|
||
| 操作 | 方法 |
|
||
|------|------|
|
||
| 接受**全部文件的所有变更** | QuickPick 底部选 `✅ Accept All`，或 `Ctrl+Shift+A` |
|
||
| 拒绝**全部文件的所有变更** | QuickPick 底部选 `❌ Reject All`，或 `Ctrl+Shift+R` |
|
||
| 手动打开总览 | 点击状态栏 `$(diff) AI Diff`，或 `Ctrl+Shift+D` |
|
||
| 查看当前文件 Diff | `Ctrl+Shift+F` |
|
||
| 在变更文件间导航 | `Alt+↑` / `Alt+↓` |
|
||
| 接受当前编辑 | `Tab`（需要在 Diff 编辑器内） |
|
||
|
||
### 逐文件审查流程
|
||
|
||
```
|
||
AI 对话进行中（静默收集 EditRecord）
|
||

|
||
Stop → QuickPick 弹窗
|
||
│
|
||
├─ 📄 file1.ts +3 -2 · 2次编辑 ← 选中回车

|
||
│ 点击 ✓ → 应用变更
|
||

|
||
│ └→ 文件处理完毕? → 自动打开下一个文件 Diff
|
||
│
|
||
├─ 📄 file2.ts +9 -1 · 1次编辑 ← 自动推进
|
||
│ └→ ... (重复)
|
||
│
|
||
└─ 🎉 所有变更已处理完毕
