+# T-Ruby WASM 기여 가이드
+
+> [English Documentation](./CONTRIBUTING.md)
+
+T-Ruby WASM에 기여해 주셔서 감사합니다! 이 문서는 기여자를 위한 가이드라인과 정보를 제공합니다.
+
+## 행동 강령
+
+모든 상호작용에서 존중과 건설적인 태도를 유지해 주세요. 모든 배경과 경험 수준의 기여자를 환영합니다.
+
+## 시작하기
+
+1. 저장소를 포크하세요
+2. 포크한 저장소를 클론하세요:
+ ```bash
+ git clone https://github.com/YOUR_USERNAME/t-ruby-wasm.git
+ cd t-ruby-wasm
+ ```
+3. 의존성을 설치하세요:
+ ```bash
+ npm install
+ ```
+4. 변경사항을 위한 브랜치를 생성하세요:
+ ```bash
+ git checkout -b feature/your-feature-name
+ ```
+
+## 개발 가이드라인
+
+### 코드 스타일
+
+- 모든 소스 파일에 TypeScript 사용
+- 기존 코드 스타일 준수
+- 각 파일은 하나의 export만 가져야 함
+- 파일은 100줄 미만으로 유지 (주석 포함)
+- 종합적인 JSDoc 주석 작성
+
+### SOLID 원칙
+
+SOLID 원칙을 따릅니다:
+
+- **S**ingle Responsibility: 각 클래스/모듈은 하나의 책임만
+- **O**pen/Closed: 확장에 열려있고 수정에 닫혀있음
+- **L**iskov Substitution: 서브타입은 대체 가능해야 함
+- **I**nterface Segregation: 인터페이스를 작고 집중적으로 유지
+- **D**ependency Inversion: 추상화에 의존
+
+### DRY 원칙
+
+같은 코드를 반복하지 마세요. 공통 로직은 재사용 가능한 유틸리티로 추출하세요.
+
+## 테스팅
+
+### 테스트 주도 개발 (TDD)
+
+TDD 방법론을 사용합니다:
+
+1. 먼저 실패하는 테스트 작성
+2. 테스트를 통과하는 최소한의 코드 작성
+3. 테스트를 통과 상태로 유지하면서 리팩토링
+
+### 테스트 실행
+
+```bash
+# 테스트 실행
+npm test
+
+# 감시 모드로 테스트 실행
+npm run test:watch
+
+# 커버리지와 함께 테스트 실행
+npm run test:coverage
+```
+
+## Pull Request 과정
+
+1. 모든 테스트가 통과하는지 확인
+2. 필요한 경우 문서 업데이트
+3. 새 기능에 대한 테스트 추가
+4. 커밋은 원자적이고 설명이 잘 되어야 함
+5. 관련 이슈 참조
+
+### 커밋 메시지 형식
+
+```
+type: 짧은 설명
+
+필요한 경우 더 긴 설명.
+
+Fixes #123

+# T-Ruby WASM
+
+[](https://www.npmjs.com/package/@t-ruby/wasm)
+[](https://opensource.org/licenses/BSD-2-Clause)
+
+> [English Documentation](./README.md)
+
+브라우저 환경에서 WebAssembly로 실행되는 T-Ruby 컴파일러입니다. 이 패키지를 사용하면 브라우저에서 직접 T-Ruby(`.trb`) 파일을 Ruby(`.rb`)로 컴파일할 수 있어, 문서화 플레이그라운드, 온라인 에디터, 교육 도구 등에 적합합니다.
+
+## T-Ruby란?
+
+[T-Ruby](https://github.com/type-ruby/t-ruby)는 TypeScript에서 영감을 받은 Ruby용 타입 레이어입니다. 타입 어노테이션이 포함된 `.trb` 파일을 표준 `.rb` 파일로 컴파일하고 `.rbs` 타입 시그니처 파일을 생성합니다. 이 패키지는 그 기능을 WebAssembly를 통해 브라우저로 가져옵니다.
+
+## 설치
+
+```bash
+npm install @t-ruby/wasm
+```
+
+## 빠른 시작
+
+```typescript
+import { createTRuby } from '@t-ruby/wasm';
+
+// T-Ruby WASM 런타임 초기화
+const tRuby = await createTRuby();
+
+// T-Ruby 코드 컴파일
+const result = await tRuby.compile(`
+ def greet(name: String): String
+ "Hello, #{name}!"
+ end
+`);
+
+if (result.success) {
+ console.log(result.ruby); // 컴파일된 Ruby 코드
+ console.log(result.rbs); // 생성된 RBS 시그니처
+} else {
+ console.error(result.errors);
+}
+```
+
+## API 레퍼런스
+
+### `createTRuby(options?)`
+
+T-Ruby 인스턴스를 생성하고 초기화합니다. 시작하는 데 권장되는 방법입니다.
+
+```typescript
+const tRuby = await createTRuby({
+ debug: false, // 디버그 로깅 활성화
+});
+```
+
+### `TRuby` 클래스
+
+더 세밀한 제어가 필요한 경우 `TRuby` 클래스를 직접 사용할 수 있습니다.
+
+```typescript
+import { TRuby } from '@t-ruby/wasm';
+
+const tRuby = new TRuby();
+await tRuby.initialize();
+```
+
+#### `compile(source, filename?)`
+
+T-Ruby 소스 코드를 Ruby로 컴파일합니다.
+
+```typescript
+const result = await tRuby.compile(`
+ interface Greeter
+ def greet(name: String): String
+ end
+
+ class HelloGreeter
+ implements Greeter
+
+ def greet(name: String): String
+ "Hello, #{name}!"
+ end
+ end
+`, 'greeter.trb');
+
+console.log(result.ruby); // 컴파일된 Ruby 코드
+console.log(result.rbs); // RBS 타입 시그니처
+console.log(result.errors); // 컴파일 에러 (있는 경우)
+console.log(result.warnings); // 컴파일 경고 (있는 경우)
+```
+
+#### `typeCheck(source, filename?)`
+
+컴파일 없이 T-Ruby 소스 코드의 타입을 검사합니다.
+
+```typescript
+const result = await tRuby.typeCheck(`
+ def add(a: Integer, b: Integer): Integer
+ a + b
+ end
+
+ add("not", "integers")
+`);
+
+if (!result.valid) {
+ result.errors?.forEach(err => {
+ console.error(`${err.line}:${err.column} - ${err.message}`);
+ });
+}
+```
+
+#### 가상 파일 시스템
+
+다중 파일 프로젝트를 위해 가상 파일 시스템의 파일을 관리합니다.
+
+```typescript
+// 개별 파일 추가
+tRuby.addFile('lib/utils.trb', `
+ def helper(x: Integer): Integer
+ x * 2
+ end
+`);
+
+// 여러 파일 추가
+tRuby.addFiles([
+ { path: 'lib/models.trb', content: '# models' },
+ { path: 'lib/services.trb', content: '# services' },
+]);
+
+// 모든 파일 가져오기
+const files = tRuby.getFiles();
+
+// 파일 제거
+tRuby.removeFile('lib/utils.trb');
+
+// 모든 파일 지우기
+tRuby.clearFiles();
+```
+
+#### `getVersion()`
+
+버전 정보를 가져옵니다.
+
+```typescript
+const versions = await tRuby.getVersion();
+console.log(versions.tRuby); // T-Ruby 버전
+console.log(versions.ruby); // Ruby 버전
+console.log(versions.rubyWasm); // Ruby WASM 버전
+```
+
+#### `eval(code)`
+
+임의의 Ruby 코드를 실행합니다 (고급 사용 사례용).
+
+```typescript
+const result = await tRuby.eval('1 + 2 + 3');
+console.log(result); // 6
+```
+
+## 타입
+
+패키지는 다음 TypeScript 타입을 내보냅니다:
+
+```typescript
+import type {
+ TRubyOptions,
+ CompileResult,
+ CompileError,
+ CompileWarning,
+ TypeCheckResult,
+ TypeCheckError,
+ VirtualFile,
+ VersionInfo,
+} from '@t-ruby/wasm';
+```
+
+## 브라우저 사용법
+
+### 번들러 사용 (Vite, Webpack 등)
+
+```typescript
+import { createTRuby } from '@t-ruby/wasm';
+
+async function main() {
+ const tRuby = await createTRuby();
+ // tRuby 사용...
+}
+
+main();
+```
+
+### CDN 사용 (ESM)
+
+```html
+
+```
+
+## 사용 사례
+
+- **문서화 플레이그라운드**: 사용자가 문서에서 직접 T-Ruby 코드를 시험해볼 수 있게 함
+- **온라인 에디터**: 브라우저 기반 T-Ruby 에디터 구축
+- **교육 도구**: T-Ruby 학습을 위한 대화형 튜토리얼 제작
+- **코드 미리보기**: 사용자가 입력하는 대로 실시간으로 컴파일 출력 표시
+
+## 요구 사항
+
+- WebAssembly를 지원하는 최신 브라우저
+- Node.js 18+ (개발/빌드용)
+
+## 개발
+
+```bash
+# 의존성 설치
+npm install
+
+# 패키지 빌드
+npm run build
+
+# 테스트 실행
+npm test
+
+# 타입 검사
+npm run typecheck
+
+# 린트
+npm run lint

+
+T-Ruby compiler running in WebAssembly for browser environments. This package allows you to compile T-Ruby (`.trb`) files to Ruby (`.rb`) directly in the browser, making it perfect for documentation playgrounds, online editors, and educational tools.
+
+## What is T-Ruby?
+
+[T-Ruby](https://github.com/type-ruby/t-ruby) is a TypeScript-inspired typed layer for Ruby. It compiles `.trb` files with type annotations into standard `.rb` files and generates `.rbs` type signature files. This package brings that functionality to the browser via WebAssembly.
+
+## Installation
+
+```bash
+npm install @t-ruby/wasm
+```
+
+## Quick Start
+
+```typescript
+import { createTRuby } from '@t-ruby/wasm';
+
+// Initialize the T-Ruby WASM runtime
+const tRuby = await createTRuby();
+
+// Compile T-Ruby code
+const result = await tRuby.compile(`
+ def greet(name: String): String
+ "Hello, #{name}!"
+ end
+`);
+
+if (result.success) {
+ console.log(result.ruby); // Compiled Ruby code
+ console.log(result.rbs); // Generated RBS signatures
+} else {
+ console.error(result.errors);
+}
+```
+
+## API Reference
+
+### `createTRuby(options?)`
+
+Creates and initializes a T-Ruby instance. This is the recommended way to get started.
+
+```typescript
+const tRuby = await createTRuby({
+ debug: false, // Enable debug logging
+ stdout: (text) => console.log(text), // Custom stdout handler
+ stderr: (text) => console.error(text), // Custom stderr handler
+});
+```
+
+### `TRuby` Class
+
+For more control, you can use the `TRuby` class directly.
+
+```typescript
+import { TRuby } from '@t-ruby/wasm';
+
+const tRuby = new TRuby();
+await tRuby.initialize();
+```
+
+#### `compile(source, filename?)`
+
+Compiles T-Ruby source code to Ruby.
+
+```typescript
+const result = await tRuby.compile(`
+ interface Greeter
+ def greet(name: String): String
+ end
+
+ class HelloGreeter
+ implements Greeter
+
+ def greet(name: String): String
+ "Hello, #{name}!"
+ end
+ end
+`, 'greeter.trb');
+
+console.log(result.ruby); // Compiled Ruby code
+console.log(result.rbs); // RBS type signatures
+console.log(result.errors); // Compilation errors (if any)
+console.log(result.warnings); // Compilation warnings (if any)
+```
+
+#### `typeCheck(source, filename?)`
+
+Type checks T-Ruby source code without compiling.
+
+```typescript
+const result = await tRuby.typeCheck(`
+ def add(a: Integer, b: Integer): Integer
+ a + b
+ end
+
+ add("not", "integers")
+`);
+
+if (!result.valid) {
+ result.errors?.forEach(err => {
+ console.error(`${err.line}:${err.column} - ${err.message}`);
+ });
+}
+```
+
+#### Virtual File System
+
+Manage files in the virtual file system for multi-file projects.
+
+```typescript
+// Add individual files
+tRuby.addFile('lib/utils.trb', `
+ def helper(x: Integer): Integer
+ x * 2
+ end
+`);
+
+// Add multiple files
+tRuby.addFiles([
+ { path: 'lib/models.trb', content: '# models' },
+ { path: 'lib/services.trb', content: '# services' },
+]);
+
+// Get all files
+const files = tRuby.getFiles();
+
+// Remove a file
+tRuby.removeFile('lib/utils.trb');
+
+// Clear all files
+tRuby.clearFiles();
+```
+
+#### `getVersion()`
+
+Get version information.
+
+```typescript
+const versions = await tRuby.getVersion();
+console.log(versions.tRuby); // T-Ruby version
+console.log(versions.ruby); // Ruby version
+console.log(versions.rubyWasm); // Ruby WASM version
+```
+
+#### `eval(code)`
+
+Execute arbitrary Ruby code (for advanced use cases).
+
+```typescript
+const result = await tRuby.eval('1 + 2 + 3');
+console.log(result); // 6
+```
+
+## Types
+
+The package exports the following TypeScript types:
+
+```typescript
+import type {
+ TRubyOptions,
+ CompileResult,
+ CompileError,
+ CompileWarning,
+ TypeCheckResult,
+ TypeCheckError,
+ VirtualFile,
+ VersionInfo,
+} from '@t-ruby/wasm';
+```
+
+## Browser Usage
+
+### With a Bundler (Vite, Webpack, etc.)
+
+```typescript
+import { createTRuby } from '@t-ruby/wasm';
+
+async function main() {
+ const tRuby = await createTRuby();
+ // Use tRuby...
+}
+
+main();
+```
+
+### Via CDN (ESM)
+
+```html
+
+```
