代码注释生成器

添加清晰、有意义的代码注释,解释复杂逻辑、函数目的、参数描述和返回值,遵循特定语言的约定。

The Code Comment Generator analyzes your code and produces professional documentation comments that follow language-specific conventions. Paste a function, class, or module and get properly formatted JSDoc, Python Docstrings, Javadoc, or XML Documentation Comments with parameter descriptions, return types, exception documentation, and usage examples. Stop writing docs manually — let AI handle the boilerplate while you focus on logic.

面向开发者的 Python 函数

为小型 Python 工具添加文档字符串和类型提示

查看输入和输出预览

输入

language
python
code
def chunk_list(lst, n): return [lst[i:i+n] for i in range(0, len(lst), n)]

输出(节选)

```python
def chunk_list(lst, n):
    """
    将列表拆分为长度为 ``n`` 的连续子列表。

    如果 ``len(lst)`` 不是 ``n`` 的整数倍,最后一个子列表可能短于 ``n``。顺序保持不变。

    参数:
        lst: 源可迭代对象,转化为类似列表的序列。
        n: 块大小。必须是正整数。

    返回:
        一个列表的列表,每个内部列表是 ``lst`` 的连续切片。

    示例:
        >>> chunk_list([1, 2, 3, 4, 5], 2)
        [[1, 2], [3, 4], [5]]
    """
    return [lst[i:i+n] for i in range(0, len(lst), n)]

JavaScript 处理函数

为库工具函数添加 JSDoc 注释

查看输入和输出预览

输入

language
javascript
code
function debounce(fn, ms){let t;return function(...args){clearTimeout(t);t=setTimeout(()=>fn.apply(this,args),ms);};}

输出(节选)

```javascript
/**
 * 将函数包装,使得间隔小于 ``ms`` 毫秒的调用合并为一次尾随调用。用于限制在
 * resize、scroll 或快速输入事件上的工作。
 *
 * @param {Function} fn - 需要防抖的函数。
 * @param {number} ms - 毫秒为单位的安静期。
 * @returns {Function} 返回一个防抖包装函数,保持 ``this`` 和参数。
 *
 * @example
 *   window.addEventListener('resize', debounce(layout, 200));
 */
function debounce(fn, ms) {
  let t;
  return function (...args) {
    clearTimeout(t);
    t = setTimeout(() => fn.apply(this, args), ms);

SQL 存储过程

记录 SQL 存储过程的操作注意事项

查看输入和输出预览

输入

language
sql
code
CREATE PROCEDURE ArchiveOldOrders @Days INT AS BEGIN INSERT INTO orders_archive SELECT * FROM orders WHERE created_at < DATEADD(day,-@Days,GETUTCDATE()); DELETE FROM orders WHERE created_at < DATEADD(day,-@Days,GETUTCDATE()); END

输出(节选)

```sql
-- 将 `orders` 中早于 @Days 的行移动到 `orders_archive`,
-- 然后从实时表中删除这些行。
--
-- @Days:以天为单位的截止年龄。满足 `created_at < UTC_NOW - @Days` 的行可归档。
--        可归档。
--
-- 注意:
--   * 在生产环境中使用事务包装,以避免部分归档。
--   * 应在 orders.created_at 和 orders_archive 上建立索引,以便
--     在超过 100 万行的表上能够在秒级而非分钟级运行。
--   * 始终使用 UTC —— 服务器本地时间会因夏令时而漂移。
CREATE PROCEDURE ArchiveOldOrders @Days INT AS
BEGIN
  INSERT INTO orders_archive
    SELECT * FROM orders
    WHERE created_at < DATEADD(day, -@Days, GETUTCDATE());
  DELETE FROM orders
    WHERE created_at < DATEADD(day, -@Days, GETUTCDATE());
END
```

Your 代码注释生成器 results will appear here

Expect clean code blocks with comments, plus a short explanation of what changed.

如何使用 代码注释生成器

  1. Paste any function, class, method, or code block you want to document.
  2. Select the programming language and comment style that matches your project's conventions.
  3. Choose a detail level: 'Brief' for quick summaries, 'Comprehensive' for full docs with examples and edge cases.
  4. Copy the generated documented code back into your editor — the comments are formatted and ready to use.

使用案例

1

Add JSDoc comments to JavaScript/TypeScript functions for IDE IntelliSense support

2

Generate Python docstrings following Google or NumPy conventions

3

Create Javadoc for Java classes and interfaces before a code review

4

Document C# public APIs with XML documentation comments for automated doc generation

5

Add comprehensive inline comments to complex algorithms for team knowledge sharing

最佳结果的技巧

  • Paste complete function signatures including type annotations — the more the AI knows about types, the better the documentation will be.
  • Use 'Comprehensive' detail level for public APIs and library interfaces that external developers will use.
  • For private/internal methods, 'Brief' level is usually sufficient — focus comprehensive docs on your public surface area.
  • The generated docs work directly with documentation generators: JSDoc, Sphinx, Javadoc, Sandcastle (C#), and godoc.

常见问题

Does it understand complex TypeScript types?

Yes. The generator handles generics, union types, intersection types, mapped types, conditional types, and complex interfaces. It will document type parameters and constraints in the JSDoc/TSDoc output.

Can I paste an entire class or module?

Yes. Paste a complete class and the generator will produce documentation for the class itself, its constructor, and all public methods. For very large files, consider documenting critical sections individually for best results.

What Python docstring format does it use?

By default, it uses Google-style docstrings (Args, Returns, Raises sections). If you prefer NumPy-style or reStructuredText, mention it in your code snippet description and the generator will adapt.

Does it generate inline comments too?

Select 'Inline Comments' as the comment style. The generator will add comments to lines where the logic is non-obvious — complex conditionals, algorithm steps, workarounds, and business rules. It avoids trivial comments like '// increment counter'.

Will it preserve my existing code?

Yes. The generator wraps your original code with documentation comments. Your code logic, formatting, and variable names remain unchanged — only comments are added above or around the relevant code blocks.

Can I use this for documenting REST API controllers?

Yes. Paste your controller/route handler code and select the appropriate language. The generator will document endpoint paths, HTTP methods, request parameters, response types, and error responses — which pairs well with OpenAPI documentation tools.
