줄바꿈을 강제하여 각 후속 줄이 길어지도록 합니다.

Question

안녕 여러분. 우리 연구소에는 몇 가지 특별한 형식 요구 사항이 있는데, 영리한 LaTex 마법을 사용하여 다음 중 하나를 자동화할 수 있는지 궁금합니다.

캡션(섹션 및 하위 섹션도 포함)은 오른쪽 정렬로 설정됩니다. 그러나 줄 바꿈은 다음 줄이 이전 줄보다 길어지는 방식입니다(유지 관리가 불가능한 마지막 줄은 제외). 그러나 마지막 줄을 완전히 \textwith로 만드는 것이 아니라 다음 줄을 조금 더 길게 만드는 첫 번째 중단점을 찾는 것입니다.

다음은 몇 가지 예입니다.

이것:

This is an example of a very long caption of a figure which might be too long to stay in one line so that it will automatically jump to a new line.

다음과 같아야 합니다:

This is an example of a very long caption of a figure which might be too long to stay in one line so that it will automatically jump to a new line instead.

This is an example of a very long caption of a figure which might be too long to stay in one line so that it will automatically jump to a new line instead but now it is even more text.

이런 서식을 자동화할 수 있는지 정말 궁금합니다.

최선을 다하세요, 베른테

Answer 1

이것은 첫 번째 줄이 절반 너비로 시작하여 점점 길어집니다... 로그에 많은 경고가 표시됩니다...

좀 더 직사각형의 블록을 얻게 됩니다.

Answer 2

마지막 줄의 추가 공간을 대체하기 위해 삼각형을 만들려고 합니다. 하이픈을 피하고 항상 전체 줄을 마지막에 작성하고 싶기 때문에 완벽하지는 않습니다. 을 주의 깊게 사용하면 실수를 수정할 수 있습니다 \rlap. 예를 들어, exam\rlap{ple}.

이는 수정하는 모든 패키지와 호환되지 않을 수 있습니다 \@makecaption.

      \dimen0=\dimexpr \count1\hsize - \wd\@tempboxa\relax% extra space      
      \ifdim \dimen0 < 0pt
        \advance \count1 by 1
        \advance \dimen0 by \hsize

      \count2=\numexpr \count1-1\relax
