### 📋 Requirements

- Python 3.10+ (for pip installation)
- Provider API keys stored in environment variables (see Configuration)

### 🔐 Configuration

Copy `example.env` to `.env` and fill in the API keys for the providers you plan to use:

```bash
cp example.env .env
```

**Environment Variables:**

| Provider  | Required Variable         | Optional Variables                 | Default Model           |
|-----------|---------------------------|------------------------------------|-------------------------|
| DeepSeek  | `DEEPSEEK_API_KEY`        | `DEEPSEEK_API_BASE`                | `deepseek-chat`         |
| OpenAI    | `OPENAI_API_KEY`          | `OPENAI_ORG`                       | `gpt-5`                 |
| Anthropic | `ANTHROPIC_API_KEY`       | —                                  | `claude-3.7-sonnet`     |
| Grok      | `GROK_API_KEY`            | `GROK_API_BASE`                    | `grok-beta`             |

> 💡 **Tip**: The CLI reads your `.env` file automatically. On macOS, add exports to `~/.zshrc` or use `direnv` for project-specific secrets.

### 🚀 Quick Start

After installation, use the `pptrans` command:

```bash
# Basic translation (no vision review - fastest)
pptrans presentation.pptx --provider openai --source-lang zh --target-lang en

# Translate all PPT files in a directory
pptrans ./presentations/ --provider openai

# With vision-based quality review (translates AND reviews in one command)
pptrans presentation.pptx --provider openai --vision-review --vision-model YOUR_VISION_MODEL_NAME --source-lang zh --target-lang en

# Customize max refinement iterations (default is 3)
pptrans presentation.pptx --provider openai --vision-review --vision-model YOUR_MODEL --max-refinement-iterations 5

# Batch translation with vision review (all files in directory)
pptrans ./presentations/ --provider openai --vision-review --vision-model YOUR_VISION_MODEL_NAME --source-lang zh --target-lang en

# Use a glossary for consistent terminology
pptrans presentation.pptx --provider openai --glossary glossary.json

# Generate review file for manual editing
pptrans presentation.pptx --provider openai --generate-review

# Regenerate PPT from edited review file
pptrans presentation.pptx --regenerate-from-review translation_review.json

# View all available options
pptrans --help
```

**Important Notes:**
- **Vision review is NOT automatic** - you must explicitly add `--vision-review` flag to enable it
- Basic translation (without `--vision-review`) is faster and uses fewer API calls
- Vision review requires a vision-capable model (specify with `--vision-model`)

### 📖 Usage

#### Basic Translation

```bash
pptrans /path/to/presentation.pptx \
  --provider openai \
  --model YOUR_MODEL_NAME \
  --source-lang zh \
  --target-lang en
```

#### Advanced Options

```bash
pptrans /path/to/decks \
  --provider openai \
  --source-lang zh \
  --target-lang en \
  --max-workers 4 \
  --max-chunk-size 2000 \
  --glossary my_glossary.json \
  --vision-review \
  --vision-quality-threshold 7.5 \
  --max-refinement-iterations 3 \
  --generate-review \
  --review-format yaml
```

#### Command-Line Options

| Option | Description | Default |
|--------|-------------|---------|
| `--provider` | Model provider: `deepseek`, `openai`, `anthropic`, `grok` | `deepseek` |
| `--model` | Override provider's default model (enter model name from your provider) | Provider default |
| `--source-lang` | Source language code (ISO 639-1) | `zh` |
| `--target-lang` | Target language code (ISO 639-1) | `en` |

**Language Support**: PPTrans accepts any ISO 639-1 language code. Actual language support depends on your chosen LLM provider's capabilities. Common codes: `zh` (Chinese), `en` (English), `ja` (Japanese), `ko` (Korean), `es` (Spanish), `fr` (French), `de` (German), etc. See [LANGUAGE_SUPPORT.md](LANGUAGE_SUPPORT.md) for details.

| `--max-workers` | Number of threads for slide processing | `4` |
| `--glossary` | Path to glossary file (JSON/YAML) | None |
| `--no-memory` | Disable translation memory | Enabled |
| `--vision-review` | Enable vision-based quality review | Disabled |
| `--vision-model` | Vision-capable model name (must support image/vision analysis) | Required if `--vision-review` enabled |
| `--vision-quality-threshold` | Minimum quality score (0-10) | `7.0` |
| `--max-refinement-iterations` | Max refinement attempts | `3` |

#### Output Files

The tool generates:

1. `{deck}_original.xml` – Source deck contents (if `--keep-intermediate`)
2. `{deck}_translated.xml` – Translated content (if `--keep-intermediate`)
3. `{deck}_translated.pptx` – Rebuilt presentation with translated text
4. `translation_review.{json|yaml}` – Review file (if `--generate-review`)

### 🎯 Key Features Explained

#### AI-Guided Autofallback & Vision Review

**Note**: PPTrans is an application that uses your chosen models - we don't provide model services. You select both the translation model and vision review model based on your needs and API access.

**Vision review is opt-in only** - it is NOT enabled by default. You must explicitly add the `--vision-review` flag to enable it. Basic translation (without vision review) is faster and uses fewer API calls.

**Important**: When you use `--vision-review`, the system **translates AND reviews in a single command**. You do NOT need to run translation first, then review separately. The workflow is:

1. **Translation**: Text is extracted and translated using your translation model
2. **Vision Review**: Translated slides are rendered and analyzed by your vision model
3. **Iterative Refinement**: If quality is below threshold, the system automatically refines the translation
4. **Output**: Final translated PPTX file is generated

**Example workflow:**
```bash
# Single command: Translates AND reviews in one go
pptrans presentation.pptx --provider openai --vision-review --vision-model gpt-4o --source-lang zh --target-lang en

# This will:
# 1. Translate the presentation (using OpenAI's default model or --model if specified)
# 2. Review the translated slides (using gpt-4o vision model)
# 3. Refine if needed
# 4. Output: presentation_translated.pptx
```

When vision review is enabled (via `--vision-review` flag), the system uses your chosen vision-capable model to visually analyze slides:

- **Pre-translation analysis**: Understands layout constraints and text hierarchy
- **Post-translation review**: Quality scoring (0-10) with specific issues and suggestions
- **AI-guided autofallback**: Automatically switches to advanced formatting methods when issues are detected:
  - **Advanced paragraph formatting**: Preserves bullets, indentation, and multi-paragraph structure
  - **TextFrame measurement**: Uses accurate text measurement instead of estimation for better font sizing
- **Iterative refinement**: Automatically improves translations until quality threshold is met
- **Prompt optimization**: Learning context is intelligently limited (~500 tokens max) to prevent prompt bloat across multiple iterations - only the most relevant and successful patterns are included

The autofallback system reads AI suggestions and intelligently enables advanced features only when needed, keeping the process efficient for simple slides while ensuring quality for complex formatting. The learning system tracks successful fixes and avoids repeating failed patterns, with prompt size management to ensure efficient API usage.

```bash
# Use your vision-capable model (enter the model name from your provider)
pptrans deck.pptx --provider openai --vision-review --vision-model YOUR_VISION_MODEL_NAME --vision-quality-threshold 8.0

# Customize max refinement iterations (how many times to retry if quality is low)
pptrans deck.pptx --provider openai --vision-review --vision-model YOUR_MODEL --max-refinement-iterations 5
```

#### Translation Memory

Stores translations in a temporary JSON file to ensure consistency:

- Reuses translations across multiple slides
- Shared across all files in a batch
- Automatically cleaned up after completion

Disable with `--no-memory` if you don't need consistency.

#### User-Defined Glossary

Define preferred translations for consistent terminology:

**glossary.json:**
```json
{
  "AI": "人工智能",
  "Machine Learning": "机器学习",
  "Neural Network": "神经网络"
}
```

```bash
pptrans deck.pptx --glossary glossary.json
```

The glossary is included in LLM prompts and applied as post-processing fallback.

#### Interactive Review Mode

Generate editable review files for manual translation editing:

```bash
# Generate review file
pptrans deck.pptx --generate-review --review-format yaml

# Edit translation_review.yaml manually, then regenerate PPT
pptrans deck.pptx --regenerate-from-review translation_review.yaml
```

Review files include:
- Original and translated texts per slide
- Quality scores and issues (if vision review enabled)
- Editable translation fields

### 🧪 Testing

Run unit tests with Pytest:

```bash
pytest
```

The test suite focuses on translation chunking/caching, CLI utilities, and provider integration.

### 🎯 核心功能说明

#### AI 引导的自动回退和视觉审查

**注意**: PPTrans 是一个使用您选择的模型的应用 - 我们不提供模型服务。您可以根据需求和 API 访问权限选择翻译模型和视觉审查模型。

**视觉审查是可选的** - 默认情况下不启用。必须显式添加 `--vision-review` 标志才能启用。基本翻译（不使用视觉审查）更快且使用更少的 API 调用。

**重要提示**: 当您使用 `--vision-review` 时，系统会在**单个命令中完成翻译和审查**。您不需要先运行翻译，然后再单独运行审查。工作流程是：

1. **翻译**: 提取文本并使用您的翻译模型进行翻译
2. **视觉审查**: 渲染翻译后的幻灯片并使用您的视觉模型进行分析
3. **迭代优化**: 如果质量低于阈值，系统会自动优化翻译
4. **输出**: 生成最终的翻译 PPTX 文件

**示例工作流程:**
```bash
# 单个命令：一次性完成翻译和审查
pptrans presentation.pptx --provider openai --vision-review --vision-model gpt-4o --source-lang zh --target-lang en

# 这将：
# 1. 翻译演示文稿（使用 OpenAI 的默认模型或指定的 --model）
# 2. 审查翻译后的幻灯片（使用 gpt-4o 视觉模型）
# 3. 根据需要优化
# 4. 输出：presentation_translated.pptx
```

启用视觉审查后（通过 `--vision-review` 标志），系统使用您选择的视觉模型来视觉分析幻灯片：

- **翻译前分析**: 理解布局约束和文本层次结构
- **翻译后审查**: 质量评分 (0-10) 并提供具体问题和建议
- **AI 引导的自动回退**: 检测到问题时自动切换到高级格式处理方法：
  - **高级段落格式**: 保留项目符号、缩进和多段落结构
  - **TextFrame 测量**: 使用准确的文本测量而非估算，实现更好的字体大小调整
- **迭代优化**: 自动改进翻译直到达到质量阈值
- **提示优化**: 学习上下文智能限制（最多约 500 个 token），防止多次迭代时提示膨胀 - 仅包含最相关和成功的模式

自动回退系统读取 AI 建议，仅在需要时智能启用高级功能，对简单幻灯片保持高效，同时确保复杂格式的质量。学习系统跟踪成功的修复并避免重复失败的模式，通过提示大小管理确保高效的 API 使用。

```bash
# 使用您的视觉模型（输入您提供商提供的模型名称）
pptrans deck.pptx --provider openai --vision-review --vision-model YOUR_VISION_MODEL_NAME --vision-quality-threshold 8.0
```

#### 翻译记忆库

将翻译存储在临时 JSON 文件中以确保一致性：

- 在多个幻灯片之间重用翻译
- 在批次中的所有文件之间共享
- 完成后自动清理

如果不需要一致性，可使用 `--no-memory` 禁用。

#### 用户定义词汇表

定义首选翻译以保持术语一致性：

**glossary.json:**
```json
{
  "AI": "人工智能",
  "Machine Learning": "机器学习",
  "Neural Network": "神经网络"
}
```

```bash
pptrans deck.pptx --glossary glossary.json
```

词汇表会包含在 LLM 提示中，并作为后处理备用方案应用。

#### 交互式审查模式

生成可编辑的审查文件以便手动编辑翻译：

```bash
# 生成审查文件
pptrans deck.pptx --generate-review --review-format yaml

# 手动编辑 translation_review.yaml，然后重新生成 PPT
pptrans deck.pptx --regenerate-from-review translation_review.yaml
```

审查文件包括：
- 每张幻灯片的原始文本和翻译文本
- 质量分数和问题（如果启用了视觉审查）
- 可编辑的翻译字段

### 🧪 测试

使用 Pytest 运行单元测试：

```bash
pytest
```
