Use: "provider",

Short: "创建新的 provider",
|
||
Long: `在 providers/<name> 目录下渲染创建 Provider 模板。
|
||
|
||
行为：
|
||
- 从内置模板 templates/provider 渲染相关文件
|
||
- 使用 name 的 CamelCase 作为导出名
|
||
- --dry-run 仅打印渲染与写入动作；--dir 指定输出基目录（默认 .）
|
||
|
||

|
||
atomctl new provider email
|
||
atomctl new --dry-run --dir ./demo provider cache`,
