如何制作一个标记数组？

我正在尝试使用梵文脚本中的一些字符来编写一个函数。我已将这些字符替换为完全不同的脚本中的其他一些字符。这是 MWE 所做的。

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Sanskrit 2003} %Any Devanagari font.
\newfontfamily{\doulo}{Doulos SIL}
\setlength{\parindent}{0cm}
\makeatletter
\catcode`\क=\active
\protected\def क{\doulo k}
\catcode`\ख=\active
\protected\def ख{\doulo kʰ}
\catcode`\ड=\active
\protected\def ड{\doulo ɖ}
\makeatother

\begin{document}
    कखड
\end{document}

Doulos SIL 字体是角色出现所必需的，可以从这里

这将产生以下内容 -

1

现在我想有条件地添加 'ə' 这个字符。只有当梵文的另一个变音符号即'्'是缺席的.（这在某种程度上意味着无论何时'्'不应添加‘ə’符号，并且对于每个不跟相同‘ə’的字符都应添加。）对于这个条件设置，我已经对此进行了编码。

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Sanskrit 2003} %Any Devanagari font.
\newfontfamily{\doulo}{Doulos SIL}    
\setlength{\parindent}{0cm}
\makeatletter
\catcode`\क=\active
\protected\def क{\bgroup\doulo k\futurelet\tmp\viramacheck}
\catcode`\ख=\active
\protected\def ख{\bgroup\doulo kʰ\futurelet\tmp\viramacheck}
\catcode`\ड=\active
\protected\def ड{\bgroup\doulo ɖ\futurelet\tmp\viramacheck}
\protected\def\viramacheck{\ifx\tmp ्\egroup\expandafter\@gobble\else ə\egroup\fi}
\makeatother

\begin{document}
    क ख ड\\
    क् ख् ड्
\end{document}

这提供了 -

对我来说，这一点很清楚。现在我想知道的是，除了有一个条件前提，即'्'我想要有一系列的前因。

例如，用逻辑语言来表达，如果 x 后面跟着् 和'A'和‘b’和'c' 不要添加 'ə'

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Sanskrit 2003} %Any Devanagari font.
\newfontfamily{\doulo}{Doulos SIL}    
\setlength{\parindent}{0cm}
\makeatletter
\catcode`\क=\active
\protected\def क{\bgroup\doulo k\futurelet\tmp\viramacheck}
\catcode`\ख=\active
\protected\def ख{\bgroup\doulo kʰ\futurelet\tmp\viramacheck}
\catcode`\ड=\active
\protected\def ड{\bgroup\doulo ɖ\futurelet\tmp\viramacheck}
\protected\def\viramacheck{\ifx\tmp ्\egroup\expandafter\@gobble\else ə\egroup\fi}
\makeatother

\begin{document}
    कaखbडc
\end{document}

输出是 -

我想要的是 -

如何制作这些条件数组，即'्'、‘a’、‘b’和‘c’？

这解决了添加字符 'ə' 的问题，但如果我们看行号 23、31 和 39，ा、ी 和 ू 定义为A，我&ː分别。它们没有出现在输出中。相反，如果我们查看第 21 行和第 45 行，अ 和 ए 分别被定义为 ə 和 e，并且它们出现在输出中。变音符号可能存在​​问题。我们能解决这个问题吗？

答案1

由于我的系统上没有合适的字体，因此这有点像是瞎猜。我的想法是进行嵌套\ifx检查，如以下结构：

\ifx\tmp X
\else
  \ifx\tmp Y
  \else
  \fi
\fi

因为您使用 来\@gobble从输入流中删除以下标记，所以您必须更加小心，因为 TeX 会在标记流中保留\else/结构的部分。因此，将删除这些标记而不是以下字符（这就是您在测试中这样做的原因）。对于嵌套 if，输入正确数量的s 太繁琐了。\fi\@gobble\expandafter\expandafter

你可以使用类似这样的宏

% use as \ifischar{X}{then part}{else part}
\def\ifischar#1{%
    \ifx\tmp#1%
        \expandafter\@firstoftwo
    \else
        \expandafter\@secondoftwo
    \fi
}

它执行相同的检查，但注意没有虚假的标记留在标记流中。你的\viramacheck宏将变成

\protected\def\viramacheck{%
    \ifischar{्}{\egroup\@gobble}{%
    \ifischar{a}{\egroup\@gobble}{%
    \ifischar{b}{\egroup\@gobble}{%
    \ifischar{c}{\egroup\@gobble}{%
        ə\egroup
    }}}}%
}

我认为这给出了正确的结果，但我不能确定。
