# Step 01 — Phase 1: 基础层

**依赖**: 无  
**参考设计**: §3.2, §6.4, §13.2

## 目标

建立公共类型定义和配置管理，为所有上层模块提供基础能力。

## 新建文件

| # | 文件 | 说明 |
|---|------|------|
| 1 | `src/types.ts` | 公共类型定义 |
| 2 | `src/config/ai.ts` | AI 配置 getter |
| 3 | `src/config/linter.ts` | Linter 配置 getter |
| 4 | `src/config/fixer.ts` | 修复器配置 getter |
| 5 | `src/config/secret.ts` | API Key SecretStorage |
| 6 | `src/config/index.ts` | 统一导出 |

## 1. `src/types.ts`

```typescript
import * as vscode from 'vscode';

export type Severity = 'error' | 'warning' | 'info';

export type AdapterStatus = 'ok' | 'tool-unavailable' | 'execution-failed';

export interface LinterDiagnostic {
  severity: Severity;
  ruleId: string;
  message: string;
  range: vscode.Range;
  suggestion?: string;
}

export interface AdapterResult {
  diagnostics: LinterDiagnostic[];
  status: AdapterStatus;
  errorMessage?: string;
}

export interface LinterAdapter {
  id: string;
  supportedLanguages: string[];
  check(document: vscode.TextDocument, workingDir: string): Promise<AdapterResult>;
  isAvailable(): boolean;
}
```

---

## 2. `src/config/ai.ts`

```typescript
import * as vscode from 'vscode';

export interface AIConfig {
  provider: string;
  model: string;
  baseUrl: string;
  temperature: number;
  timeout: number;
  outputLanguage: string;
}

export function getAIConfig(): AIConfig {
  const config = vscode.workspace.getConfiguration('vscode-code-reviewer');
  return {
    provider: config.get<string>('ai.provider', 'deepseek'),
    model: config.get<string>('ai.model', 'deepseek-chat'),
    baseUrl: config.get<string>('ai.baseUrl', 'https://api.deepseek.com/v1'),
    temperature: config.get<number>('ai.temperature', 0.2),
    timeout: config.get<number>('ai.timeout', 300),
    outputLanguage: config.get<string>('ai.outputLanguage', 'zh-CN'),
  };
}
```

**配置 Key**（前缀 `vscode-code-reviewer.`）:

| Key | 类型 | 默认值 |
|-----|------|--------|
| `ai.provider` | enum | `deepseek` |
| `ai.model` | string | `deepseek-chat` |
| `ai.baseUrl` | string | `https://api.deepseek.com/v1` |
| `ai.temperature` | number | 0.2 |
| `ai.timeout` | number | 300 |
| `ai.outputLanguage` | string | `zh-CN` |

## 3. `src/config/linter.ts`

```typescript
import * as vscode from 'vscode';

export interface LinterConfig {
  languageMap: Record<string, string>;
  pmdJarPath: string;
  pmdRulesetPath: string;
  pmdJspRulesetPath: string;
  sqlLintConfigFile: string;
}

export function getLinterConfig(): LinterConfig {
  const config = vscode.workspace.getConfiguration('vscode-code-reviewer');
  return {
    languageMap: {
      javascript: config.get<string>('linters.javascript', 'eslint'),
      typescript: config.get<string>('linters.typescript', 'eslint'),
      java: config.get<string>('linters.java', 'pmd'),
      jsp: config.get<string>('linters.jsp', 'jsp'),
      css: config.get<string>('linters.css', 'stylelint'),
      sql: config.get<string>('linters.sql', 'sql-lint'),
      plsql: config.get<string>('linters.plsql', 'sql-lint'),
    },
    pmdJarPath: config.get<string>('pmd.jarPath', ''),
    pmdRulesetPath: config.get<string>('pmd.rulesetPath', ''),
    pmdJspRulesetPath: config.get<string>('pmd.jspRulesetPath', ''),
    sqlLintConfigFile: config.get<string>('sql-lint.configFile', ''),
  };
}
```

| Key | 类型 | 默认值 | enum |
|-----|------|--------|------|
| `linters.javascript` | enum | `eslint` | `""` / `eslint` |
| `linters.typescript` | enum | `eslint` | `""` / `eslint` |

| `linters.plsql` | enum | `sql-lint` | `""` / `sql-lint` |
| `pmd.jarPath` | string | `""` | — |
| `pmd.rulesetPath` | string | `""` | — |
| `pmd.jspRulesetPath` | string | `""` | — |
| `sql-lint.configFile` | string | `""` | — |

## 4. `src/config/fixer.ts`

```typescript
import * as vscode from 'vscode';

export interface FixerConfig {
  contextLines: number;
}

export function getFixerConfig(): FixerConfig {
  const config = vscode.workspace.getConfiguration('vscode-code-reviewer');
  return {
    contextLines: config.get<number>('fixer.contextLines', 5),
  };
}
```

## 5. `src/config/secret.ts`

```typescript
import * as vscode from 'vscode';

const SECRET_KEY = 'vscode-code-reviewer.apiKey';

export async function getApiKey(context: vscode.ExtensionContext): Promise<string | undefined> {
  return context.secrets.get(SECRET_KEY);
}

export async function setApiKey(context: vscode.ExtensionContext, key: string): Promise<void> {
  await context.secrets.store(SECRET_KEY, key);
}

export async function deleteApiKey(context: vscode.ExtensionContext): Promise<void> {
  await context.secrets.delete(SECRET_KEY);
}

export async function isApiKeyConfigured(context: vscode.ExtensionContext): Promise<boolean> {
  const key = await getApiKey(context);
  return !!key;
}
```

## 6. `src/config/index.ts`

```typescript
export { getAIConfig, AIConfig } from './ai';
export { getLinterConfig, LinterConfig } from './linter';
export { getFixerConfig, FixerConfig } from './fixer';
export { getApiKey, setApiKey, deleteApiKey, isApiKeyConfigured } from './secret';
```
