답변 헤더 뒤에 공백이 남지 않는 이유는 무엇입니까?

Question

연습문제와 패키지의 답변 헤더도 exercise같은 방식으로 재정의했습니다.

연습 헤더 뒤에는 답 헤더 번호 뒤에 약간의 공간이 정확하게 남아 있습니다.

물론 답변 헤더의 정의에 수동으로 넣을 수도 있는데, 패키지의 버그인지 아니면 제가 잘못한 것인지 궁금합니다.

Answer 1

\@@@ExeEnv답은 and 의 정의에 있습니다 .\@@@AnswerEnv

% exercise.sty, line 365:
\newcommand{\@@@ExeEnv}{%
    \pagebreak[1]\vskip\ExerciseSkipBefore
    \@QuestionLevel1
    \refstepExecounter
    \begingroup\@getExerciseInfo\ExerciseHeader
    \addcontentsline{\ext@exercise}{\toc@exercise}{\ExerciseName\
        \theExercise\ \expandafter{\itshape \ExerciseTitle}\hspace{.66em}}
    \endgroup\AtBeginExercise}

% exercise.sty, line 656:
\newcommand{\@@@AnswerEnv}{%
    \pagebreak[1]\vskip\AnswerSkipBefore\@QuestionLevel1
    \begingroup\@getAnswerInfo\AnswerHeader\endgroup\AtBeginAnswer}

보시다시피 371번째 줄에는 보호되지 않은 줄 끝이 있는데, 이것이 “연습 1.1” 이후에 공간을 생성하는 것입니다.

Answer 2

나에게는 버그인 것 같다. 정의 끝에 공백 추가

\renewcommand{\AnswerHeader}{\noindent\bfseries\AnswerName\ \thechapter.\ExerciseHeaderNB. }
%                                                                                        ^^^

해결 방법으로 문제를 해결합니다. 제 생각에는 \xspace패키지의 솔루션 헤더 텍스트 정의에 누락된 것 같습니다 .

문서에서 찾을 수 있습니다.

\newcommand{\AnswerHeader}{\medskip\centerline{\textbf{Answer of \ExerciseName\ \ExerciseHeaderNB}\smallskip}}

나에게는 놀라운 일이다\smallskip끝에 가 있습니다 .
