make list-skills

开发

添加新技能

  1. 在根目录下创建新的技能目录(使用连字符命名)
  2. 实现技能逻辑
  3. pyproject.toml[project.scripts] 中添加命令入口
  4. [tool.hatch.build.targets.wheel] 中添加包名和映射

示例结构:

cz_skills/
├── pyproject.toml
├── Makefile
├── README.md
├── job-performance-analyzer/      # 目录名用连字符
│   ├── __init__.py
│   ├── __main__.py               # 包含 main() 函数
│   └── ...
├── sql-history-expert/
│   ├── __init__.py
│   ├── __main__.py
│   └── ...
└── your-new-skill/               # 新技能
    ├── __init__.py
    ├── __main__.py
    └── ...

pyproject.toml 中添加:

[project.scripts]
cz-your-skill = "your_skill.__main__:main"

[tool.hatch.build.targets.wheel]
packages = ["job-performance-analyzer", "sql-history-expert", "your-new-skill"]

[tool.hatch.build.targets.wheel.force-include]
"job-performance-analyzer" = "job_performance_analyzer"
"sql-history-expert" = "sql_history_expert"
"your-new-skill" = "your_skill"

运行测试

make test

构建发布

# 构建
make build

# 上传到 PyPI(需要配置 twine)
make upload
