AI自动生成Git提交信息-git AI Commit

网友: 技术文档 2025-08-08 13:32:15

在现代软件开发中，编写清晰且一致的Git提交信息对于维护项目历史和促进团队协作至关重要。然而，为每次变更手动撰写描述性提交信息可能耗时，尤其是处理复杂差异或大型项目时。AI Commit 是一个利用AI分析Git差异并生成符合Conventional Commits规范的提交信息的Python脚本。本文将介绍其工作原理、核心功能以及如何优化您的开发流程。
AI自动生成Git提交信息-git AI Commit

什么是AI Commit？

AI Commit 是一个Python工具，通过分析暂存的Git变更（git diff --cached）并利用大型语言模型（LLM）生成简洁、上下文相关的提交信息。它集成了外部API（如阿里云的Qwen模型），能够识别代码变更类型（功能添加、错误修复、重构等），并生成符合规范的提交信息，确保项目历史清晰易懂。

核心功能

1. 智能差异分析

脚本解析Git差异，提取关键信息：

  • 文件变更：识别新增、修改和删除的文件。
  • 变更类型：检测重构、功能添加、错误修复、文档更新或配置变更。
  • 优先文件分析：重点关注重要文件类型（如.py、.js、.java）。
  • 变更范围：判断变更影响单个文件、模块或多个项目部分。

对于大型差异或多文件项目，AI Commit生成简洁摘要，保留关键细节。

2. 上下文感知的提交信息

AI Commit根据变更类型生成符合Conventional Commits规范的提交信息，例如：

  • 文档更新：使用docs:前缀（例：docs: 更新README中的安装说明）。
  • 测试变更：使用test:前缀（例：test: 添加用户认证单元测试）。
  • 错误修复：使用fix:前缀（例：fix: 修复数据解析中的空指针异常）。
  • 新功能：使用feat:前缀（例：feat: 实现用户配置文件API端点）。
  • 代码重构：使用refactor:前缀（例：refactor: 将工具函数提取到独立模块）。
  • 配置变更：使用chore:或config:前缀（例：chore: 更新package.json中的依赖）。

这确保提交信息与工具如semantic-release兼容，便于生成变更日志。

3. 支持新项目初始化

脚本能检测新项目的初始提交（例如包含README.md、package.json或.gitignore等文件），生成类似init: 初始化项目结构的提交信息。

4. 处理大型差异

对于超过8000字符或涉及10个以上文件的差异，AI Commit通过以下方式进行智能处理：

  • 按文件类型分组（例：5个.py文件，2个.js文件）。
  • 提取关键变更，如函数或类定义。
  • 提供分层摘要，包含变更类型、主要语言和范围。

5. 健壮的错误处理

脚本处理多种错误情况，包括：

  • Git命令缺失或无效。
  • API请求失败（如超时或HTTP错误）。
  • 环境变量（如QWEN_API）缺失。
  • 无效或空差异。

提供清晰的错误信息，便于开发者排查问题。

工作流程

以下是脚本的工作流程图，使用Mermaid展示：

  1. 获取差异：运行git diff --cached获取暂存变更。
  2. 分析差异：解析文件变更、添加/删除行数及模式。
  3. 摘要生成：对于大型差异，生成简洁摘要或提取关键变更。
  4. 生成提示：根据变更类型创建上下文感知的提示。
  5. 调用API：将差异或摘要发送至LLM API生成提交信息。
  6. 执行提交：使用git commit -m 提交。

示例代码

以下是核心代码片段，展示如何分析差异并生成提交信息：

def analyze_diff(diff): \"\"\"分析diff内容，返回文件变更摘要\"\"\" lines = diff.split(\'\\n\') files_info = { \'new_files\': [], \'modified_files\': [], \'deleted_files\': [], \'total_additions\': 0, \'total_deletions\': 0 } current_file = None for line in lines: if line.startswith(\'diff --git\'): match = re.search(r\'a/(.*?) b/(.*?)$\', line) if match: current_file = match.group(2) elif line.startswith(\'new file mode\'): if current_file: files_info[\'new_files\'].append(current_file) elif line.startswith(\'deleted file mode\'): if current_file: files_info[\'deleted_files\'].append(current_file) elif line.startswith(\'index\') and current_file: if current_file not in files_info[\'new_files\'] and current_file not in files_info[\'deleted_files\']: files_info[\'modified_files\'].append(current_file) elif line.startswith(\'+\') and not line.startswith(\'+++\'): files_info[\'total_additions\'] += 1 elif line.startswith(\'-\') and not line.startswith(\'---\'): files_info[\'total_deletions\'] += 1 return files_infodef get_commit_message(request_body): \"\"\"调用 API 生成提交信息\"\"\" headers = { \"Authorization\": f\"Bearer {API_KEY}\", \"Content-Type\": \"application/json\" } try: response = requests.post(API_URL, headers=headers, json=request_body, timeout=REQUEST_TIMEOUT) response.raise_for_status() return response.json() except requests.exceptions.Timeout: print(f\"[ERROR] API 请求超时 ({REQUEST_TIMEOUT} 秒)。\") return None

示例使用

假设您在一个Python项目中暂存了变更并运行脚本，输出可能如下：

[INFO] 请求体内容：{ \"model\": \"qwen-plus-latest\", \"temperature\": 0.3, \"messages\": [ { \"role\": \"system\", \"content\": \"你是一个专业程序员。这是新功能相关的变更，请生成符合 conventional commits 规范的提交信息，使用 \'feat:\' 前缀。仅返回一行，不要解释。\" }, { \"role\": \"user\", \"content\": \"新增文件: src/api.py, tests/test_api.py; +50 -0 行\" } ]}[INFO] 生成的提交信息： feat: 添加用户认证API端点[OK] 已提交。

生成的提交信息清晰、规范，准确反映变更内容。
