당신이 그것을 거부하지 않기로 선택한 경우, 당신의 선택은 당신이 선택한 언어로 주어진 코드의 조각을 "골프"하는 프로그램을 작성하는 것입니다.

기본 기능

• 불필요한 공백 제거
• 댓글 제거

'고급'기능 :

• 선언 결합 ( int x; int y; int z;to int x, y, z;)
• 더 짧은 기본 제어 구조를 사용하십시오 ( while(1)로 대체 됨 for(;;))
• 이동 코드 주위에 ( i = 0; while(i < 10) { /* ... */ ++i; }로 for(i = 0; i < 10; ++i) { /* ... */ })
• 기타

파이썬과 파이썬

변수 이름 바꾸기, 불필요한 공백 및 주석 제거 및 한 줄에 가능한 한 많이 넣는 것을 포함하여 많은 것들을 수행합니다. 항상 더 멋진 파이썬 구문으로 완벽하게 작동하지는 않으며 수정 사항으로 계속 업데이트 할 것입니다.

작동 원리

실행 불가능한 모든 문자를 제거한 후 다음을 수행합니다. 적중 카운터는 -1시작시 설정되며 외부 루프가 실행될 때마다 수행 된 골프 작업 수를 계산합니다.

1. 골프를 치고있는 코드가 비어 있으면 5 단계로 이동하십시오.
2. 코드에서 처음 두 문자를 읽고 첫 번째 문자를 제거하십시오.
3. 이러한 경우 <>, ><, +-또는 -+의 1을 추가 hits카운터 단계 1로 돌아갑니다.
4. 그렇지 않은 경우 출력 할 첫 번째 문자를 저장하고 1 단계로 이동하십시오.
5. 적중 카운터가 0이면 출력을 인쇄하고 종료하십시오.
6. 그렇지 않으면 적중 카운터를 0으로 재설정하고 골프 코드를 출력 변수로 설정하고 출력을 빈 문자열로 재설정 한 다음 1 단계로 이동하십시오.

배쉬의 HQ9 + 골퍼 (v3)

나는 HQ9 +가 쓸모가 없다는 것을 알고 있지만 5 라이너를 제출할 수도 있습니다. 그것은 읽습니다표준 입력파일. 파일 경로는 첫 번째 명령 줄 인수 여야합니다.

풍모

• 모든 주석 문자를 제거합니다 (제외 HhQq9+)
• 제거합니다 +(숫자는 증가하지만 그 숫자를 인쇄 할 방법은 없습니다)
• hq대문자로 변환 (골프 아님)

암호

#!/bin/bash
if [ -f $1 ]; then
input=`cat $1`
else exit 1; fi
echo $input|tr "[[:lower:]]" "[[:upper:]]"|grep -o "[HQ9]"|tr -d ' \n'
exit 0

자바와 자바

파일 이름을 명령 행 인수로 사용하여 파일을 적절하게 편집합니다.

• 주석을 제거합니다
• 식별자 (클래스, 메소드, 변수, 메소드 매개 변수 및 람다 표현식 매개 변수 포함)를 줄입니다.
• 공간 정리
• 수입을 단축
• 한 줄 문장에서 불필요한 괄호를 제거합니다
• 변환 while(true)에for(;;)
• 같은 불필요한 수정, 삭제 private및final

프로그램이 자체적으로 실행될 때 크기는 7792에서 4366으로 줄어 듭니다.

( #작은 따옴표 안의 주석을 제거하고 문자를 무시 합니다)

(괄호와 =기호 뒤의 모든 공백을 제거합니다 )

나는이 코드를 골프하려고하지 않았다. 어쩌면 골프가 끝났을 수도 있습니다.

$/="\n\n";
chomp($prog = <>);
for(1..length($prog)){
 $rev.=chop $prog;
}
#print$rev;
for(1..length($rev)){
 $temp = chop$rev;
 if ($temp eq '"'){
  if($quote == 0){$quote = 1}
  else{$quote = 0}
 }
 if($temp eq '#' && $quote == 0){$comment = 1}
 if($temp eq "\n"){
  $comment = 0;
 }
 if($comment != 1){
  $prog.=$temp;
 }

입력 예

for(1..10) {
 print "Hello, World!";#prints hello world
 print ($n = <>); #prints "#"
}

산출

for(1..10){print "Hello, World!";print ($n =<>);}

다음으로, 기호와 영숫자 문자 사이의 공백을 제거합니다.

Perl의 Java 골퍼

지금은 WIP이지만 꽤 좋은 코드를 얻습니다.

풍모:

• 모든 댓글을 제거합니다
• 불필요한 공백을 제거합니다
• 패키지 선언을 제거합니다 (어쨌든 단일 파일입니다).
