코드 러너
따라서 흥미로운 점을 만들기 위해 게시 된 모든 답변에서 코드를 자동으로 다운로드하고 필요한 경우 컴파일 한 다음 규칙에 따라 모든 솔루션을 실행하는 스크립트를 만들었습니다. 이런 식으로 사람들은 자신이하는 일을 확인할 수 있습니다. 이 스크립트를 run_all.py (BeautifulSoup 필요)에 저장 한 후 다음을 수행하십시오.
usage:
To get the latest code: 'python run_all.py get'
To run the submissions: 'python run_all.py run <optional num_runs>'
몇 가지:
- 더 많은 언어에 대한 지원을 추가하거나 다른 언어에 대한 지원을 제거하려면을 참조하십시오
def submission_type(lang).
- 컴파일이 필요한 언어의 경우에도 스크립트 확장은 상당히 쉬워야합니다 (참조
CPPSubmission). 언어 유형은 메타 코드 태그에서 가져 오므로 코드 < !-- language: lang-java -- >를 실행하려면 추가해야합니다 (<> 앞뒤에 추가 공백 제거).
업데이트 : 언어가 정의되지 않은 경우 언어를 시도하고 감지하는 매우 기본적인 추론이 있습니다.
- 코드가 전혀 실행되지 않거나 할당 된 시간 내에 완료되지 않으면 코드가 추가되어
blacklist.text향후 시험에서 자동으로 제거됩니다. 코드를 수정 한 경우 블랙리스트에서 항목을 제거하고 다시 실행하십시오 get.
