yummyTranslator

最近阅读英文文献，发现原有翻译流 (沙拉划词+Quiker) 由于Chrome安全策略原因失效。加之本人有学习英语的兴趣及其阅读英文文档的需求，萌生了开发一款 Translator Hub的想法。因此 Yummy Translator 诞生。此LOG记录整个项目的开发历程。

8.27（建项、架构确立）

通过与 Gemini 的”深入交流“，确定了以 React + Tauri的架构开发

模块	核心组件	技术选型/设计模式	主要职责与优势
应用框架	桌面端应用	Tauri (Rust + Web UI)	高性能、低资源占用，提供原生级的体验。
表现层	用户界面 (UI)	Web技术 (React)	利用现代前端生态，实现高效、美观、灵活的界面开发。
核心逻辑层	Rust 后端	Tauri Command & Event System	Rust保证了后端的稳定、安全和高并发处理能力。
服务层	翻译服务	适配器模式 (Adapter Pattern)	高扩展性、低耦合，未来增加新的翻译源无需修改核心代码。
服务层	输入修正服务	纯本地离线库	瞬时响应、完全离线、保护隐私，提升核心输入体验。
数据层	本地化存储	SQLite 数据库	功能强大、数据安全，为未来复杂的单词本功能铺平道路。

以 MVP的策略开发，先构建第一版v1 实现最基础的翻译功能

• 程序主界面
• 翻译结果界面
• 翻译API接入
• 本地化存储词典
• 输入修正（修正 多余复制进去的标点、以及拼错情况）

9.14 （Prompt工程）

对于 React + Tauri 的前端开发, 本人的只有些许 H5 DOM的开发经验。为了提升整个开发效率，采用高度依赖Ai agent的形式开发。由于成本限制 本项目主要采用 Github Copilot 免费模型开发。

/*
 * Project Brief for GitHub Copilot
 *
 * Project Name: Yummy Translator
 *
 * ## 1. Project Vision
 * A high-performance, multi-engine desktop translation application built with Tauri. The primary goal is to provide English learners and professionals with accurate and context-rich translations by aggregating results from multiple sources. The application must be fast, lightweight, and respect user privacy.
 *
 * ## 2. Core Features (Version 1.0)
 * - Main UI: A clean interface for text input and displaying multiple translation results side-by-side.
 * - Multi-API Aggregation: Fetch and display translation results simultaneously from different providers (e.g., Google Translate, DeepL, etc.).
 * - Input Correction:
 * - Automatically sanitize pasted text (e.g., remove extra line breaks).
 * - Provide fast, local spell-checking for English input.
 * - Local Storage:
 * - Store translation history.
 * - A basic vocabulary book to save words and phrases.
 *
 * ## 3. V1 Technical Architecture & Decisions
 * We have made the following architectural decisions. Please generate code that aligns with this stack and these patterns.
 *
 * - **Framework:** Tauri (Rust backend, web-based frontend).
 * - **Backend Language:** Rust.
 * - **Frontend Framework:** Modern web framework (e.g., Vue.js or React) using TypeScript.
 * - **Database:** SQLite for all local data storage.
 * - It will manage tables for `settings`, `translation_history`, and `vocabulary_book`.
 *
 * - **Design Pattern for Translation APIs:** We will use the **Adapter Pattern**.
 * - A core `Translator` trait will define the common interface.
 * - Each translation service (Google, DeepL, etc.) will be implemented as a separate struct that implements this `Translator` trait.
 * - Example of the core trait in Rust:
 * ```rust
 * pub trait Translator {
 * fn name(&self) -> &str;
 * async fn translate(&self, text: &str, source_lang: &str, target_lang: &str) -> Result<String, anyhow::Error>;
 * }
 * ```
 *
 * - **Input Correction Service:** This must be a **purely local and offline** feature for speed and privacy.
 * - Use Rust's native string manipulation and regex for punctuation sanitization.
 * - Use a local, dictionary-based Rust crate for spell-checking (e.g., a hunspell binding or similar). **Do not use online APIs for this feature.**
 *
 * - **State Management:** The Rust backend will be the single source of truth. The frontend will communicate with the backend via Tauri commands for data fetching and mutations.
 *
 * I will now start building this "Yummy Translator" project with your assistance based on the above specifications.

采用了单向数据流 (One-Way Data Flow) 和状态提升 (Lifting State Up) 的架构方案，App 组件通过 props 将状态数据传递给子组件(SearchBox、SuggestionDropdown.tsx etc...),子组件再将UI样式回传回 App进行调用渲染。

9.16（组件及其参数）

剖析一下程序的组件及其参数

App.tsx

先把主要控制处理组件 App 列出

import React, { useState, useRef } from "react";

   */

  const [searchValue, setSearchValue] = useState("");
  const [showDropdown, setShowDropdown] = useState(false);
  const [isActivated, setIsActivated] = useState(false);
  const [results, setResults] = useState<Array<{ name: string; result: string }>>([]);
  const inputRef = useRef<HTMLInputElement>(null);

  // 输入内容 过滤建议
  const filteredSuggestions = SUGGESTIONS.filter(
    (word) => searchValue && word.startsWith(searchValue.toLowerCase())
  );

  // 模拟API返回结果（仅演示用）
  function getApiResults(word: string): Array<{ name: string; result: string }> {
    return [
      {

        result: `${word} 的 Google 翻译结果占位。`
      },
      {
        name: "DeepL 翻译",
        result: `${word} 的 DeepL 翻译结果占位。`
      },

        name: "有道翻译",
        result: `${word} 的有道翻译结果占位。`
      }
    ];
  }


  // 处理下拉选项点击或回车选择
  function handleSelect(word: string) {
    setSearchValue(word);
    setShowDropdown(false);
    setIsActivated(true);
    setResults(getApiResults(word));
  }

  // 处理输入框内容变化
  function handleInputChange(e: React.ChangeEvent<HTMLInputElement>) {
    const value = e.target.value;
    setSearchValue(value);
  setShowDropdown(!!value && filteredSuggestions.length > 0);
  }

  // 处理回车键事件
  function handleKeyDown(e: React.KeyboardEvent<HTMLInputElement>) {
    if (e.key === "Enter" && searchValue) {
      setShowDropdown(false);
      setIsActivated(true);
      setResults(getApiResults(searchValue));
    }

        background: "none",
      }}
    >
      {/* 搜索框和下拉建议 */}
      <Box
        sx={{
          position: isActivated ? "fixed" : "absolute",
          top: isActivated ? 32 : "50%",
          left: "50%",
          transform: isActivated ? "translate(-50%, 0)" : "translate(-50%, -50%)",
          width: 400,
