Question

패키지에 대해 다음 코드를 고려하십시오.

% Preamble
\NeedsTeXFormat{LaTeX2e}[1994/06/01]
\ProvidesPackage{mypackage}[2024/01/01 MyPackage]
\makeatletter

% Dependencies
\RequirePackage{pgfopts}
\RequirePackage{xparse}
\RequirePackage{xcolor}

% Package options
\pgfkeys{
    /mypackage/.cd,
    firstcolor/.store in = \mypackage@firstcolor,
    firstcolor = blue,
    secondcolor/.store in = \mypackage@secondcolor,
    secondcolor = red,
}
\ProcessPgfPackageOptions{/mypackage}

% Definition of `\setcolors` here

% Definition of `\resetcolors` here

% Definition of `\printcolors` here

% Definition of `\newcolortheme` here

% End
\makeatother

다음 동작으로 다음 세 가지 함수를 정의하고 싶습니다.

• \setcolors: 문서의 나머지 부분에 대한 변경 firstcolor및 secondcolor호출 시점
• \resetcolors: setcolors에 의한 모든 변경 사항을 잊어버리고 패키지의 원래 옵션으로 되돌립니다.
• \printcolors: 기본적으로 현재 전역 firstcolor및 를 사용 secondcolor하지만 전역 값을 로컬 값으로 재정의하는 선택적 매개변수가 있습니다.
• \newcolortheme: 두 쌍에 특별한 이름을 부여하기 위해 색상 테마를 생성할 수 있는 가능성을 제공합니다 firstcolor.secondcolor

사용자 측에서는 다음과 같이 보입니다.

\documentclass[12pt]{article}
\usepackage[firstcolor = green, secondcolor = yellow]{mypackage}
\newcolortheme{mytheme}{firstcolor = brown, secondcolor = cyan}

\begin{document}
\printcolors                      % Will print green and yellow
\printcolors[secondcolor = blue]  % Will print green and blue
\printcolors                      % Will print green and yellow

\setcolors{secondcolor = black}
\printcolors                      % Will print green and black
\printcolors[firstcolor = purple] % Will print purple and black
\printcolors                      % Will print green and black

\setcolors{firstcolor = red}
\printcolors                      % Will print red and black

\setcolors{firstcolor = orange, secondcolor = pink}
\printcolors                      % Will print orange and pink

\resetcolors
\printcolors                      % Will print green and yellow
\printcolors[mytheme]             % Will print brown and cyan
\printcolors                      % Will print green and yellow

\setcolors{mytheme}
\printcolors                      % Will print brown and cyan      
\end{document}

나는 그것을 어떻게 할 수 있는지 전혀 모른다.

질문 :\setcolors, \resetcolors, 를 어떻게 정의 \printcolors하고 \newcolortheme그렇게 만들까요?

Answer 1

가능한 방법은 다음과 같습니다.

\resetcolors
\printcolors                      % Will print green and yellow
\printcolors[my theme]            % Will print brown and cyan
\printcolors                      % Will print green and yellow

\setcolors{my theme}
\printcolors                      % Will print brown and cyan      
\end{document}

(참고: \setcolor매크로는 의 별칭과 같습니다 \mypackage@set.)

Answer 2

다음은 \printcolors그룹화 없이 이를 달성하는 두 가지 방법을 보여줍니다(바람직할 수도 있고 그렇지 않을 수도 있음).

이 두 코드는 모두 제품군의 패키지를 사용합니다 expkv(부인 성명:그 중 제가 저자입니다). 첫 번째는 expkv-cs핵심에서 사용하므로 그룹이 필요하지 않은 코드 작성이 매우 간단해집니다(key=value 처리기는 할당이 필요하지 않으므로 매크로는 \printcolors할당 없이 확장만으로 작동합니다. 제외하는 경우). 이 주장의 선택적 인수에 대한 구문 분석). 두 번째는 단순히 각 호출에서 기본값을 재설정하고(성능이 좋은 방식으로) \setcolors기본값으로 다시 설정하는 데 사용되는 매크로를 변경합니다.
