How to add \printindex to tableofcontents

Question

I want to add the \indexname to the table of contents and to the bookmarks.

Now, I know one way to do this job: add the follow code before \printindex:

\phantomsection
\cleardoublepage
\addcontentsline{toc}{chapter}{\indexname}

but I want to move all the styling or customize code to single one .sty file

Anybody knows how to do this through renew \printindex command or some method can define in a .sty file?

EDIT： add the MWE

\documentclass{book}
\usepackage{makeidx}
\usepackage{hyperref}
\usepackage{lipsum}


\makeindex
\begin{document}

\frontmatter
\tableofcontents


\mainmatter
\chapter{one}
\lipsum[1]
\index{word}

\backmatter
\appendix
\phantomsection
\cleardoublepage
\addcontentsline{toc}{chapter}{\indexname}
\printindex


\end{document}

Answer 1

Three ways.

1. tocbibind

   \usepackage{makeidx}
   \makeindex
   \usepackage[nottoc]{tocbibind}
   

2. idxlayout

   \usepackage{makeidx}
   \makeindex
   \usepackage[totoc]{idxlayout}
   

3. imakeidx

   \usepackage{imakeidx}
   \makeindex[intoc]
   

With methods 2 and 3 you have also that the last page of the index is balanced.

Answer 2

I've struggled with the very same problem, trying to make tocbibind make what I wanted it to. (add Index to TOC). Unfortunately with the above tocbibind-answer, the link (using hyperref) jumps to the chapter before the index. In my case, this is the bibliography. I fixed this by editing the tocbibind.sty file (you can probably do this in your own .sty-file). However, this solution requires the multicol package.

First of all, I added the following line after ProvidesPackage :

\RequirePackage{multicol}

Then, I re-defined the \printindex command, which adds a \chapter or \chapter* in front of the index environment (I think the actual pain in the a** is that the generated .ind file only holds the theindex environment and no command for adding the chapter/section/ other caption):

\if@inltxdoc\else
  \renewcommand{\printindex}{
    \if@bibchapter
      \if@donumindex
        \chapter{\indexname}
      \else
        \chapter*{\indexname}
          \if@dotocind
            \addcontentsline{toc}{chapter}{\indexname}
          \fi
        \fi
      \fi
    \addcontentsline{toc}{chapter}{\indexname}
    \@input@{\jobname.ind}
  }
\fi

Finally, in the code renewing the theindex environment I deleted the stuff from the \if@bibchapter branch (which now only reads \begin{multicols}{2}) and added the according \if@bibchapter\end{multicols}\fi into the environment's ending code:

\if@inltxdoc\else
  \renewenvironment{theindex}%
    {\if@twocolumn
       \@restonecolfalse
     \else
       \@restonecoltrue
     \fi
     \if@bibchapter
        \begin{multicols}{2}
     \else
        \if@donumindex
          \twocolumn[\vspace*{-1.5\topskip}%
                     \@nameuse{\@tocextra}{\indexname}]%
          \csname \@tocextra mark\endcsname{\indexname}
        \else
          \if@dotocind
            \twocolumn[\vspace*{-1.5\topskip}%
                       \toc@headstar{\@tocextra}{\indexname}]%
            \prw@mkboth{\indexname}
            \addcontentsline{toc}{\@tocextra}{\indexname}
          \else
            \twocolumn[\vspace*{-1.5\topskip}%
                       \toc@headstar{\@tocextra}{\indexname}]%
            \prw@mkboth{\indexname}
          \fi
        \fi
     \fi
   \thispagestyle{plain}\parindent\z@
   \parskip\z@ \@plus .3\p@\relax
   \let\item\@idxitem}
   {\if@bibchapter\end{multicols}\fi\if@restonecol\onecolumn\else\clearpage\fi}
\fi

Now the index page has the very same chapter caption and the hyperref link works.

Answer 3

Here is what I did and seems to be working well. Add TOC request when you make the index:

\makeindex[columns=3, title=Alphabetical Index, intoc]
