我正在尝试将命令数组传递给新命令或使用带有“includesvg”的“for”循环的定义

我从以下问题中学到了：

我试图将祖先列表作为数组与新命令或定义或新命令与定义作为数组传递到相同的新命令或相同的定义。

以下是小代码：

\documentclass{standalone}
\usepackage{graphicx}
\usepackage{pgffor}
\usepackage{svg}
\usepackage[all]{genealogytree}
\newlength{\mypx}
\setlength{\mypx}{0.013889in}

\newcommand\Ancestries[1]
{
    \def\ancestrieslist{#1}
    \foreach \ancestry in \ancestrieslist 
    {
        \includesvg[width={10\mypx}]{assets/images/flags/twemoji/\ancestry.svg}\par
    }
}

\begin{document}

    \linespread{1.5}
    \begin{tikzpicture}
        \genealogytree
        {
            parent
            {
                g[id = 01, male, box = {title = Self}]
                {
                    \textbf{Ancestries}\\
                    \Ancestries{argentina, brazil, italy, portugal, spain}\\
                }
            }
        }
    \end{tikzpicture}
\end{document}

我还尝试了另外两种方法：

\newcommand{\Ancestries}[1]
{
    \foreach \x in {#1} 
    {%
        \includesvg[width={10\mypx}]{assets/images/flags/twemoji/\x.svg}\par%
    }
}

\def\Ancestries#1
{%
  \foreach \x in {#1} 
  {%
    \includesvg[width={10\mypx}]{assets/images/flags/twemoji/\x.svg}\par%
  }
}

结果应如下所示：

\textbf{Ancestries}\\
\includesvg[width={10\mypx}]{assets/images/flags/twemoji/argentina.svg}
\includesvg[width={10\mypx}]{assets/images/flags/twemoji/brazil.svg}
\includesvg[width={10\mypx}]{assets/images/flags/twemoji/italy.svg}
\includesvg[width={10\mypx}]{assets/images/flags/twemoji/portugal.svg}
\includesvg[width={10\mypx}]{assets/images/flags/twemoji/spain.svg}

错误

LaTeX Error: There's no line here to end.

通常在垂直模式下使用时会抛出\\。在您的情况下，这是由\\之后引起的\Ancestries{argentina, brazil, italy, portugal, spain}，因为在每个条目之后\Ancestries您都放置了一个\par，因此这实际上会导致\par\\，然后您就会收到该错误。

编译结果如下：

\documentclass{standalone}
\usepackage{graphicx}
\usepackage{pgffor}
\usepackage{svg}
\usepackage[all]{genealogytree}
\newlength{\mypx}
\setlength{\mypx}{0.013889in}

\newcommand\Ancestries[1]
  {%
    \foreach \ancestry in {#1}% 
      {%
        \rule{10\mypx}{10\mypx}\par
        %\includesvg[width={10\mypx}]{assets/images/flags/twemoji/\ancestry.svg}\par
      }%
  }

\begin{document}

    \linespread{1.5}
    \begin{tikzpicture}
        \genealogytree
        {
            parent
            {
                g[id = 01, male, box = {title = Self}]
                {
                    \textbf{Ancestries}\\
                    \Ancestries{argentina, brazil, italy, portugal, spain}
                }
            }
        }
    \end{tikzpicture}
\end{document}
