快速搜索工具Everything
要在Electron + TypeScript + Vite项目中调用Everything.dll实现快速搜索,可以按照以下步骤进行操作:
1. 安装Everything软件并启动它,确保Everything.dll已经被正确安装。
2. 在项目中安装node-ffi和ref-napi,这两个模块可以帮助我们在Node.js中调用DLL函数。可以使用以下命令进行安装:
```bash
npm install node-ffi ref-napi
```
3. 创建一个名为everything.ts的TypeScript模块,并在其中定义我们要调用的Everything.dll函数。可以参考以下代码:
```typescript
import { FFI } from 'ffi-napi';
/**
* Everything.dll中的函数声明
*/
export interface EverythingDLL extends FFI.Library {
Everything_SetSearchW: (search: Buffer) => void;
Everything_QueryW: (wait: number) => void;
Everything_GetNumResults: () => number;
Everything_GetResultFullPathNameW: (index: number, buf: Buffer, size: number) => number;
Everything_CleanUp: () => void;
}
/**
* 加载Everything.dll
*/
const everythingDll: EverythingDLL = FFI.Library('Everything.dll', {
Everything_SetSearchW: ['void', ['pointer']],
Everything_QueryW: ['void', ['int']],
Everything_GetNumResults: ['int', []],
Everything_GetResultFullPathNameW: ['int', ['int', 'pointer', 'int']],
Everything_CleanUp: ['void', []],
});
export default everythingDll;
```
4. 在项目中使用everything.ts模块来进行搜索。可以参考以下代码:
```typescript
import everythingDll from './everything';
/**
* 搜索文件
* @param search 搜索关键字
* @returns 搜索结果数组
*/
export function searchFiles(search: string): string[] {
// 将搜索关键字转为UTF-16编码的Buffer
const searchBuffer = Buffer.from(search, 'ucs2');
// 设置搜索关键字
everythingDll.Everything_SetSearchW(searchBuffer);
// 执行搜索
everythingDll.Everything_QueryW(1);
// 获取搜索结果数量
const resultCount = everythingDll.Everything_GetNumResults();
// 获取搜索结果
const results: string[] = [];
for (let i = 0; i < resultCount; i++) {
const buf = Buffer.alloc(4096);
everythingDll.Everything_GetResultFullPathNameW(i, buf, buf.length);
const result = buf.toString('ucs2');
results.push(result);
}
// 清理搜索结果
everythingDll.Everything_CleanUp();
return results;
}
```
5. 在Electron应用程序中使用searchFiles函数进行搜索。可以参考以下代码:
```typescript
import { app, BrowserWindow } from 'electron';
import { searchFiles } from './everything';
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true,
},
});
win.loadFile('index.html');
// 在渲染进程中使用searchFiles函数进行搜索
win.webContents.on('did-finish-load', () => {
const results = searchFiles('test');
console.log(results);
});
}
app.whenReady().then(() => {
createWindow();
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});
});
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
```
这样就可以在Electron + TypeScript + Vite项目中调用Everything.dll实现快速搜索了。
