-# LoRA Manager Internationalization (i18n)
-
-This document explains how to use the internationalization system in LoRA Manager.
-
-## Features
-
-- Automatic language detection based on browser language
-- Support for English (en) and Simplified Chinese (zh-CN)
-- Fallback to English if the browser language is not supported
-- Dynamic text replacement in HTML templates
-- Number, date, and file size formatting according to locale
-- Right-to-Left (RTL) language support (framework ready)
-
-## Browser Language Detection
-
-The system automatically detects the user's browser language using:
-1. `navigator.language` - Primary browser language
-2. `navigator.languages[0]` - First language in the user's preferred languages
-3. Fallback to 'en' if no supported language is found
-
-### Supported Language Codes
-
-- `en` - English (default)
-- `zh-CN` - Simplified Chinese
-- `zh` - Falls back to Simplified Chinese
-
-## Usage in HTML Templates
-
-### Basic Text Translation
-
-Add the `data-i18n` attribute to any HTML element:
-
-```html
-<span data-i18n="header.appTitle">LoRA Manager</span>
-<button data-i18n="common.actions.save">Save</button>
-```
-
-### Placeholder and Attribute Translation
-
-For form inputs and other attributes:
-
-```html
-<input type="text" data-i18n="header.search.placeholder" data-i18n-target="placeholder" placeholder="Search..." />
-<button data-i18n="loras.controls.refresh.title" data-i18n-target="title" title="Refresh model list">
-```
-
-### Translation with Parameters
-
-For dynamic content with variables:
-
-```html
-<span data-i18n="loras.bulkOperations.selected" data-i18n-params='{"count": 5}'>5 selected</span>
-```
-
-## Usage in JavaScript
-
-### Import the i18n Helper
-
-```javascript
-import { t, formatFileSize, formatDate, formatNumber } from './utils/i18nHelpers.js';
-```
-
-### Basic Translation
-
-```javascript
-// Simple translation
-const message = t('common.status.loading');
-
-// Translation with parameters
-const selectedText = t('loras.bulkOperations.selected', { count: 5 });
-```
-
-### Dynamic DOM Updates
-
-```javascript
-import { setTranslatedText, setTranslatedAttribute, updateBulkSelectionCount } from './utils/i18nHelpers.js';
-
-// Update text content
-setTranslatedText('#myButton', 'common.actions.save');
-
-// Update attributes
-setTranslatedAttribute('#myInput', 'placeholder', 'header.search.placeholder');
-
-// Update bulk selection count
-updateBulkSelectionCount(selectedItems.length);
-```
-
-### Formatting Functions
-
-```javascript
-// Format file size
-const sizeText = formatFileSize(1048576); // "1 MB" or "1 兆字节"
-
-// Format date
-const dateText = formatDate(new Date(), { year: 'numeric', month: 'long', day: 'numeric' });
-
-// Format number
-const numberText = formatNumber(1234.56, { minimumFractionDigits: 2 });
-```
-
-## Page Initialization
-
-Each page should call `initializePageI18n()` after the DOM is loaded:
-
-```javascript
-import { initializePageI18n } from './utils/i18nHelpers.js';
-
-document.addEventListener('DOMContentLoaded', async () => {
-    // Initialize core application
-    await appCore.initialize();
-    
-    // Initialize page-specific functionality
-    const myPage = new MyPageManager();
-    await myPage.initialize();
-    
-    // Initialize i18n for the page
-    initializePageI18n();
-});
-```
-
-## Translation Key Structure
-
-Translation keys use dot notation for nested objects:
-
-```
-common.actions.save          → "Save" / "保存"
-header.navigation.loras      → "LoRAs" / "LoRA 模型"
-loras.controls.sort.nameAsc  → "A - Z" / "A - Z"
-```
-
-### Key Categories
-
-- `common.*` - Shared terms and actions
-- `header.*` - Header and navigation
-- `loras.*` - LoRA page specific
-- `recipes.*` - Recipe page specific
-- `checkpoints.*` - Checkpoint page specific
-- `embeddings.*` - Embedding page specific
-- `statistics.*` - Statistics page specific
-- `modals.*` - Modal dialogs
-- `errors.*` - Error messages
-- `success.*` - Success messages
-- `keyboard.*` - Keyboard shortcuts
-- `tooltips.*` - Tooltip text
-
-## Adding New Languages
-
-1. Create a new language file in `static/js/i18n/locales/`:
-
-```javascript
-// Example: fr.js for French
-export const fr = {
-    common: {
-        actions: {
-            save: 'Sauvegarder',
-            cancel: 'Annuler',
-            // ...
-        },
-        // ...
-    },
-    // ...
-};
-```
-
-2. Import and register the language in `static/js/i18n/index.js`:
-
-```javascript
-import { fr } from './locales/fr.js';
-
-class I18nManager {
-    constructor() {
-        this.locales = {
-            'en': en,
-            'zh-CN': zhCN,
-            'zh': zhCN,
-            'fr': fr,  // Add new language
-        };
-        // ...
-    }
-}
-```
-
-## Best Practices
-
-1. **Keep keys descriptive**: Use clear, hierarchical key names
-2. **Consistent naming**: Follow the established pattern for similar elements
-3. **Fallback text**: Always provide fallback text in HTML for graceful degradation
-4. **Context-aware**: Group related translations logically
-5. **Parameter usage**: Use parameters for dynamic content instead of string concatenation
-6. **Testing**: Test with different languages to ensure UI layout works properly
-
-## RTL Language Support
-
-The system includes framework support for RTL languages:
-
-```javascript
-// Check if current language is RTL
-if (i18n.isRTL()) {
-    document.documentElement.setAttribute('dir', 'rtl');
-    document.body.classList.add('rtl');
-}
-```
-
-Add CSS for RTL support:
-
-```css
-.rtl {
-    direction: rtl;
-}
-
-.rtl .some-element {
-    text-align: right;
-    margin-right: 0;
-    margin-left: auto;
-}
-```

-# 服务端渲染 I18n 实现总结
-
-## 问题分析
-
-原始的纯前端i18n方案存在以下问题：
-1. **语言闪烁问题**：页面首次加载时会显示英文，然后才切换到用户设置的语言
-2. **首屏渲染慢**：需要等待JavaScript加载并执行才能显示正确的语言
-3. **SEO不友好**：搜索引擎爬虫看到的是默认语言内容
-
-## 解决方案
-
-实现了**混合式服务端+客户端i18n系统**：
-
-### 1. 服务端 I18n 管理器 (`py/services/server_i18n.py`)
-
-**功能**：
-- 解析JavaScript格式的语言文件（`.js`文件中的`export const`语法）
-- 提供Jinja2模板过滤器支持
-- 支持嵌套键值查找（如`header.navigation.loras`）
-- 支持参数插值（`{param}`和`{{param}}`语法）
-- 自动回退到英语翻译
-
-**核心特性**：
-```python
-# 设置语言
-server_i18n.set_locale('zh-CN')
-
-# 获取翻译
-title = server_i18n.get_translation('header.appTitle')
-
-# 创建模板过滤器
-template_filter = server_i18n.create_template_filter()
-```
-
-### 2. 模板层面的改进
-
-**修改的文件**：
-- `templates/base.html` - 添加服务端翻译数据预设
-- `templates/components/header.html` - 使用服务端翻译
-- `templates/loras.html` - 标题和初始化消息服务端渲染
-
-**模板语法示例**：
-```html
-<!-- 服务端渲染 -->
-<span class="app-title">{{ t('header.appTitle') }}</span>
-
-<!-- 动态内容仍使用客户端 -->
-<span data-i18n="dynamic.content">Content</span>
-```
-
-### 3. 路由层面的集成
-
-**修改的文件**：
-- `py/routes/base_model_routes.py` - 基础模型路由
-- `py/routes/recipe_routes.py` - 配方路由  
-- `py/routes/stats_routes.py` - 统计路由
-- `py/routes/misc_routes.py` - 添加语言设置API
-
-**路由实现**：
-```python
-# 获取用户语言设置
-user_language = settings.get('language', 'en')
-
-# 设置服务端i18n语言
-server_i18n.set_locale(user_language)
-
-# 为模板环境添加i18n过滤器
-self.template_env.filters['t'] = server_i18n.create_template_filter()
-
-# 模板上下文
-template_context = {
-    'user_language': user_language,
-    't': server_i18n.get_translation,
-    'server_i18n': server_i18n,
-    'common_translations': {
-        'loading': server_i18n.get_translation('common.status.loading'),
-        # ... 其他常用翻译
-    }
-}
-```
-
-### 4. 前端混合处理器 (`static/js/utils/mixedI18n.js`)
-
-**功能**：
-- 协调服务端和客户端翻译
-- 避免重复翻译已经服务端渲染的内容
-- 处理动态内容的客户端翻译
-- 支持语言切换（触发页面重新加载）
-
-**工作流程**：
-1. 检查`window.__SERVER_TRANSLATIONS__`获取服务端预设的翻译
-2. 导入客户端i18n模块
-3. 同步客户端和服务端的语言设置
-4. 只翻译需要客户端处理的剩余元素
-
-### 5. API支持
-
-**新增API端点**：
-- `POST /api/set-language` - 设置用户语言偏好
-- `GET /api/get-language` - 获取当前语言设置
-
-### 6. 语言文件扩展
-
-**新增翻译内容**：
-```javascript
-initialization: {
-    loras: {
-        title: 'Initializing LoRA Manager',
-        message: 'Scanning and building LoRA cache...'
-    },
-    checkpoints: {
-        title: 'Initializing Checkpoint Manager', 
-        message: 'Scanning and building checkpoint cache...'
-    },
-    // ... 其他模块的初始化消息
-}
-```
-
-## 实现效果
-
-### 🎯 解决的问题
-
-1. **✅ 消除语言闪烁**：首屏内容直接以用户设置的语言渲染
-2. **✅ 提升首屏性能**：关键UI元素无需等待JavaScript即可显示正确语言
-3. **✅ 改善SEO**：搜索引擎可以抓取到本地化内容
-4. **✅ 保持兼容性**：动态内容仍使用前端i18n，现有功能不受影响
-
-### 🔧 技术优势
-
-1. **渐进式增强**：服务端渲染提供基础体验，客户端增强交互功能
-2. **智能协调**：避免重复翻译，优化性能
-3. **回退机制**：如果服务端翻译失败，自动回退到客户端翻译
-4. **统一管理**：使用相同的语言文件，保持翻译一致性
-
-### 🎨 用户体验提升
-
-- **即时显示**：页面打开即显示用户语言，无等待时间
-- **无缝切换**：语言切换通过页面重载，确保所有内容都正确翻译
-- **一致性**：服务端和客户端使用相同翻译源，避免不一致
-
-## 部署说明
-
-1. 现有的JavaScript语言文件无需修改
-2. 服务端会自动解析并缓存翻译数据
-3. 用户的语言偏好保存在`settings.json`中
-4. 页面刷新后自动应用服务端翻译
-
-## 兼容性
-
-- ✅ 保持现有前端i18n功能完整
-- ✅ 支持所有现有语言（en, zh-CN, zh-TW, ru, de, ja, ko, fr, es）
-- ✅ 向后兼容现有的`data-i18n`属性
-- ✅ 支持复杂的动态内容翻译
-
-此实现完美解决了原始问题，在不破坏现有功能的前提下，显著提升了用户体验和应用性能。
