\ellipsis
우리는 4개의 인수를 취하고 다음 동작을 갖는 매크로를 정의하고 싶습니다 :
\ellipsis{x^{#DUMMY#}}{0}{5}{+}
그리고 출력:
패턴 문자열 #DUMMY#
(정확한 문자열일 필요는 없음)은 두 번째 및 세 번째 인수로 대체되어야 합니다. 따라서 첫 번째 주장은 매크로 자체의 정의입니다.
우리는 몇 가지를 시도했지만 결국에는 원하는 동작을 얻기 위해 항상 두 가지 다른 매크로를 사용하게 되었습니다. 예를 들어
\newcommand{\ellipMacro}[1]{x^{#1}}
\newcommand{\ellip}[4]{\csuse{#1}{#2}#4\ldots #4 \csuse{#1}{#3}}
\csuse
이는 패키지의 제어 시퀀스를 사용합니다.etoolbox(어떤 패키지를 사용해도 괜찮습니다).
우리는 이것을 단번에 하고 싶습니다하나명령이므로 내부 매크로( x^{#DUMMY}
)의 정의는 더 큰 매크로의 정의 내에 배치되어야 합니다.
이를 수행하는 방법에 대한 아이디어를 포함해 주십시오.

인수가 자리 표시자의 끝에 오는 예제의 경우 내부 명령을 정의할 필요가 없지만 일반적인 경우 양식은 \ellipsisb
단일 인수 명령 정의의 본문을 첫 번째 인수로 사용합니다. 이를 통해 끝에 표시된 0^2...5^2 형식이 허용됩니다.

답변3
아마도 나는 당신이 원하는 것을 이해하지 못하지만 내가 아는 한 \csuse
여기서는 필요하지 않으며 다음을 정의할 수 있습니다.
\newcommand\ellip[4]{{#1}^{#3}#2\dots#2{#1}^{#4}}
이 방법으로 각각 $\ellip x+04$ 및 $\ellip y-{-1}2$가 생성됩니다.
매크로를 지원하는 더 멋진 버전이 정말로 필요하다면 지수에 매크로를 넣지 말고 대신 다음 x^
으로 바꾸는 것이 좋습니다 \csuse{#1}
.
\newcommand\fancyellip[4]{\csuse{#1}{#3}#2\dots#2\csuse{#1}{#4}}
이제 $\fancyellip{xint}-{1}2$가 생성됩니다.
의 적절한 정의를 위해 \xint
.
전체 코드는 다음과 같습니다.
