更改 tikz 中線條顏色的宏

Question

我對 tikz 和乳膠宏都很陌生，感謝您的幫助。我有兩個類似圖的簡單程式碼，如下所示：

\documentclass{article}
\usepackage{tikz}

\newcommand\tpdrrr{
\tikz{
\draw [dashed] (-1.5,.5) arc (90:-90:.5); % q1 right inner arc
\draw [red,thick] (-1.5,.5) arc (90:270:.5); % q2 left inner arc
\draw  [red,thick]  (-1.5,-.5) -- (-1.5,-1); % q3 vertical top
\draw  [red,thick] (-1.5,.5) -- (-1.5,0); % q4 inner vertical

}
}

\newcommand\tprdrr{
\tikz{
\draw [red,thick] (-1.5,.5) arc (90:-90:.5); % q1 right inner arc
\draw [dashed] (-1.5,.5) arc (90:270:.5); % q2 left inner arc
\draw  [red,thick]  (-1.5,-.5) -- (-1.5,-1); % q3 vertical top
\draw  [red,thick] (-1.5,.5) -- (-1.5,0); % q4 inner vertical

}
}

\begin{document}

\[\tprdrr + \tpdrrr \]

\end{document}

有人可以幫助我將這兩個宏合併為一個宏，我可以將線條樣式（虛線與紅色，粗線）作為參數提供，即接受例如\tp{r}{d}{r}{r}並輸出當前結果的代碼\tprdrr？我想使用更多配置，例如\tp{r}{r}{r}{r}，\t{d}{d}{d}{d}等等，因此巨集將非常有用

Answer 1

使用該ifthen套件允許您編寫更短的單字母參數。此處，rforred, thick和任何其他字母 for dashed,thoughd也足夠了。

\documentclass{article}
\usepackage{tikz}

\usepackage{ifthen}
\newcommand{\tp}[4]{
\tikz{%
\ifthenelse{\equal{#1}{r}}
    {\draw [red,thick] (-1.5,.5) arc (90:-90:.5); }
    {\draw [dashed] (-1.5,.5) arc (90:-90:.5); }

\ifthenelse{\equal{#2}{r}}
    {\draw [red,thick] (-1.5,.5) arc (90:270:.5);  }
    {\draw [dashed] (-1.5,.5) arc (90:270:.5);  }
    
\ifthenelse{\equal{#3}{r}}
    {\draw [red,thick] (-1.5,-.5) -- (-1.5,-1);   }
    {\draw [dashed] (-1.5,-.5) -- (-1.5,-1);   }
    
  \ifthenelse{\equal{#4}{r}}
    {\draw [red,thick] (-1.5,.5) -- (-1.5,0);   }
    {\draw [dashed] (-1.5,.5) -- (-1.5,0);   }  
     
}
}
\begin{document}


\tp{r}{d}{r}{r} + \tp{d}{r}{r}{r} + \tp{r}{r}{r}{r} + \tp{d}{d}{d}{d}

\end{document}

Answer 2

作為在單一巨集中滿足您需求的應用程式。

\documentclass{article}
\usepackage{tikz}

\newcommand{\tp}[4]{
\tikz{%
    \draw [#1] (-1.5,.5) arc (90:-90:.5); 
    \draw [#2] (-1.5,.5) arc (90:270:.5); 
    \draw [#3] (-1.5,-.5) -- (-1.5,-1); 
    \draw [#4] (-1.5,.5) -- (-1.5,0); 
}
}

\begin{document}

\[
    \tp{red,thick}{dashed}{red,thick}{red,thick} % <= tprdrr
\]

\[
    \tp{dashed}{red,thick}{red,thick}{red,thick} % <= \tpdrrr
\]

\[
    \tp{red,thick}{red,thick}{red,thick}{red,thick} % <=  all parts are red and thick
\]

\[
    \tp{dashed}{dashed}{dashed}{dashed} % <=  all parts are dashed
\]

\end{document}

當你看到很多重複時...這意味著它可以改進:)
