⚡ Bolt: [문자열 연결 최적화] - #788
seonghobae wants to merge 4 commits into
Conversation
루프 내에서 변수를 인라인으로 포함하는 문자열 템플릿을 사용하여 HTML을 렌더링하면, 다수의 중간 객체가 할당되어 가비지 컬렉션(GC) 성능에 부정적인 영향을 미칩니다. 이를 `StringBuilder.append()` 체이닝 방식으로 리팩토링하고 반복 호출되던 불변의 이스케이프 문자열을 재사용함으로써 메모리 낭비를 없애고 실행 속도를 개선했습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

링크에 aria-label을 추가하세요.
현재 링크에는 aria-label이 없습니다. escapedFileName과 typeLabel을 결합한 값은 안전하며, 파일명과 항목 유형을 함께 제공합니다.

💡 What:
src/main/kotlin/html4tree/main.kt내process_dir함수의 파일 목록 순회 시 HTML 요소 생성을 위해 사용하던 인라인 문자열 템플릿("""...""","${...}") 구문을 직접적인StringBuilder.append()호출 체이닝으로 변경했습니다.escapedFileName으로 미리 계산하여 렌더링 시 재사용하도록 수정했습니다.🎯 Why:
StringBuilder와 중간 문자열 인스턴스가 반복적으로 생성되어 가비지 컬렉터(GC)에 상당한 부하를 가합니다. 특히 파일 렌더링 부분은 가장 빈번하게 호출되는 로직이므로, 여기서 발생하는 미세한 객체 할당 최적화가 전체 처리량 개선으로 이어집니다.📊 Impact:
