# 子命令实现
## 何时使用
为 DevKeel CLI 新增一个子命令时（如 `harness <new-cmd>`）。
## 流程
### Step 1: 注册命令
在 `src/index.ts` 中添加：
```typescript
import { runNewCmd } from './commands/new-cmd.js'
program
.command('new-cmd')
.description('中文功能描述')
.option('--flag', '选项说明')
.action((opts) => runNewCmd(opts))
```
### Step 2: 实现命令层
创建 `src/commands/new-cmd.ts`：
```typescript
import * as p from '@clack/prompts'
import { someLogic } from '../lib/new-cmd.js'
export async function runNewCmd(opts?: { flag?: boolean }): Promise<void> {
p.intro('harness new-cmd')
// 交互 + 调用 lib
p.outro('完成')
}
```
命令层只做：读参数 → 交互 → 调用 lib → 输出结果。
### Step 3: 实现逻辑层
创建 `src/lib/new-cmd.ts`：
- 纯函数，不引入 `@clack/prompts`
- 文件操作前 `fs.existsSync` 守卫
- 返回 plain object 或 null，不 throw
### Step 4: 编写测试
创建 `tests/new-cmd.test.ts`：
- 临时目录隔离（`fs.mkdtempSync`）
- 真实文件系统验证
- 覆盖正常路径 + 缺失输入 + 幂等性
### Step 5: 验证
```bash
pnpm lint && pnpm test && pnpm build
node bin/devkeel.js new-cmd --help
```
## Checklist
- [ ] `src/index.ts` 注册命令
- [ ] `src/commands/new-cmd.ts` 交互层
- [ ] `src/lib/new-cmd.ts` 逻辑层（如有复杂逻辑）
- [ ] `tests/new-cmd.test.ts` 测试
- [ ] `pnpm lint` + `pnpm test` 通过Read the whole file at its exact version.
How to install
mdr add minleev5/devkeel/new-subcommand@v1.0.0mdr add minleev5/devkeel/new-subcommand@sha256:83b813cff1129487Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
