強制的に改行し、後続の各行が長くなるようにします。

Question

皆さん、こんにちは。私たちの研究所には特別なフォーマット要件があり、そのうちの 1 つを LaTex の巧妙な魔法で自動化できないかと考えています。

キャプション (セクションとサブセクションも同様) は、不揃いに設定されています。ただし、改行は、次の行が前の行よりも長くなるように行われます (維持できない場合は、最後の行を除く)。ただし、最後の行を完全に \textwith にすることを意図しているのではなく、次の行を少し長くする最初のブレークポイントを見つけます。

以下にいくつか例を挙げます。

これ：

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.

こうなるはずです:

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.

この種のフォーマットを自動化できるかどうか、本当に興味があります。

頑張ってください、ベルンテ

Answer 1

これは、最初の行が半分の幅で始まり、その後長くなります...ログに多くの警告が表示されます...

より長方形のブロックが得られます。

Answer 2

これは、最後の行の余分なスペースを置き換えるために三角形を作成しようとします。ハイフネーションを避けて常に最後の行が完全な行になるようにしたいので、まだ完璧ではありません。 を慎重に使用することで間違いを修正できます\rlap。たとえば、 ですexam\rlap{ple}。

これはおそらく、 を変更するすべてのパッケージと互換性がありません\@makecaption。
