我想自定义我的索引，所以我使用了latex makeindex -s myfile.ist texfile.idx latex汇编。
myfile.ist 包含：
%
heading_prefix "{\\bfseries\\hfil "
heading_suffix "\\hfil}\\nopagebreak\n"
headings_flag 1
%
delim_0 "\\dotfill"
delim_1 "\\dotfill"
delim_2 "\\dotfill"
我的 TeX 文件包含：
% arara: pdflatex: { synctex: on }
% arara: makeindex
% arara: pdflatex: { synctex: on }

\end{document}
我收到错误信息：
Undefined control sequence. \item preface \dotfill
我尝试删除delim_* "\\dotfill"或\index{preface}，两种情况均有效。那么frontmatter和中的索引delim_* "\\dotfill"兼容吗？
答案1
当我尝试您的代码时，LaTeX 抱怨\dotfillii未定义。因此我得出结论，ii前言中的页码是在添加后直接添加的delim_0。
我查看了生成的.ind文件并发现
\begin{theindex}
{\bfseries\hfil A\hfil}\nopagebreak
\item annxes\dotfill4, 6
\indexspace
{\bfseries\hfil E\hfil}\nopagebreak
\item epilogue\dotfill7
\indexspace
{\bfseries\hfil I\hfil}\nopagebreak
\item intro\dotfill2
\indexspace
{\bfseries\hfil P\hfil}\nopagebreak
\item preface\dotfillii
\end{theindex}
不是预期的
\begin{theindex}
{\bfseries\hfil A\hfil}\nopagebreak
\item annxes\dotfill 4, 6
\indexspace
{\bfseries\hfil E\hfil}\nopagebreak
\item epilogue\dotfill 7
\indexspace
{\bfseries\hfil I\hfil}\nopagebreak
\item intro\dotfill 2
\indexspace
{\bfseries\hfil P\hfil}\nopagebreak
\item preface\dotfill ii
\end{theindex}
添加空间是合乎逻辑的结论。
