API 文档生成

Python 支持

# src/calculator.py
def calculate_discount(price: float, rate: float = 0.1) -> float:
    """
    Calculate discounted price.
    
    Args:
        price: Original price
        rate: Discount rate (0-1), default 0.1 (10%)
    
    Returns:
        Discounted price
    
    Raises:
        ValueError: If price is negative
    
    Example:
        >>> calculate_discount(100.0, 0.2)
        80.0
    """
    if price < 0:
        raise ValueError("Price cannot be negative")
    return price * (1 - rate)

生成的文档：

## calculate_discount

```python

Calculate discounted price.

Args:

price (float): Original price
rate (float): Discount rate (0-1), default 0.1 (10%)

Returns:

float: Discounted price

Raises:

ValueError: If price is negative

>>> calculate_discount(100.0, 0.2)
80.0


### JavaScript 支持

```javascript
/**
 * Calculate total price with tax
 * @param {number} price - Original price
 * @param {number} taxRate - Tax rate (0-1)
 * @returns {number} Total price with tax
 * @throws {Error} If price is negative
 */
function calculateTotal(price, taxRate = 0.08) {
  if (price < 0) throw new Error('Price cannot be negative');
  return price * (1 + taxRate);
}

README 更新

自动生成目录

python3 scripts/main.py readme --update-toc

自动在 README 中插入/更新目录：

## Table of Contents

- [Installation](#installation)
- [Usage](#usage)
- [API Reference](#api-reference)
- [Contributing](#contributing)

生成功能列表

python3 scripts/main.py readme --generate-features --source src/

从代码中提取所有公开函数，生成功能列表。

架构图生成

Mermaid 图

python3 scripts/main.py diagram --format mermaid --output docs/arch.md

生成：

```mermaid
graph TD
    A[Client] --> B[API Layer]
    B --> C[Service Layer]
    C --> D[Database]
    C --> E[Cache]


### DOT 图 (Graphviz)

```bash
python3 scripts/main.py diagram --format dot --output docs/arch.dot

文档同步检查
