17.2. IndexIn order to make LaTeX collect indexing information the declaration \makeindex must beput in the preamble. By default the raw index data is put into the jobname.idx file. Ifthe optional 〈file〉 argument is given then index data can be output to file.idx. Several\makeindex declarations can be used provided they each call for a different file.The \printindex command will print an index where by default the indexed itemsare assumed to be in a file called jobname.ind. If the optional 〈file〉 argument is giventhen the indexed items are read from the file called file.ind.\begin{theindex} entries \end{theindex}\onecolindex \twocolindex\indexnameThe index entries are typeset within the theindex environment. By default it is typesetwith two columns but following the \onecolindex declaration the environment uses asingle column. The default two column behaviour is restored after the \twocolindexdeclaration. The index title is given by the current value of \indexname (default ‘Index’).\indexintoc \noindexintocThe declaration \indexintoc will cause the theindex environment to add the title to theToC, while the declaration \noindexintoc ensures that the title is not added to the ToC.The default is \indexintoc.\indexcolsep\indexruleThe length \indexcolsep is the width of the gutter between the two index columns Thelength \indexrule, default value 0pt, is the thickness of a vertical rule separating the twocolumns.\preindexhookThe macro \preindexhook is called after the title is typeset and before the index listingstarts. By default it does nothing but can be changed. For example\renewcommand{\preindexhook}{Bold page numbers are usedto indicate the main reference for an entry.}\indexmark\indexmark may be used in pagestyles for page headers in an index. Its default definitionis:\newcommand*{\indexmark}{}but could be redefined like, say,\renewcommand*{\indexmark}{\markboth{\indexname}{\indexname}}\ignorenoidxfile\reportnoidxfile303
