[Tex/LaTex] Sort index entries

indexingsorting

This question is similar to others, but I could not find an answer that actually works for me.

This is my document:

\usepackage[splitindex]{imakeidx}
\makeindex[name=n, title=Nomi di persone e luoghi] 
\makeindex[name=p, title=Passi citati nel testo]
\makeindex[name=t, title=Altri testi citati]
\makeindex[name=pap, title=Papiri e manoscritti citati nel testo]

I have 600 pages+ of text with index entries marked as follow:

\index[p]{Erodoto!8!32-3}
\index[p]{Erodoto!1!65}
%etc.

This is because I want the index to sort by book and then by chapter. The result in the index at chapter level however is sorted in the following way:

1-4, 279 (this is a range)
1.9, 74 (after the dot are lines in the chapter of the text quoted)
10-11, 357, 359
105-6, 80, 304
105.3-106.1, 75
105.4-108.2, 75
107-114, 305
2, 24
24, 56
207, 67
3, 78

Please, could you suggest me what I need to do so that things are ordered like:

1-4, 279
1.11.1-4, 74
1.9, 74
2, 24
3, 78
10-11, 357, 359
24, 56

You can use xindy instead of makeindex. It applies merging rules and it is already ready for cases like yours. We can even customize it by preparing new location classes and setting their order if we run into an unusual situation. This is a snippet from the samplexdy-mc.xdy file (it is a part of the glossaries package) where this approach was used in a large-scale.

(define-location-class "Roman-page-numbers-roman-page-numbers"
   ( :sep "{" "roman-numbers-uppercase" :sep "}{" "roman-numbers-lowercase" :sep "}" )
   :min-range-length 2
)

(define-location-class-order (
   "roman-page-numbers"
   "arabic-page-numbers"
   "arabic-section-numbers"
   "alpha-page-numbers"
   "Roman-page-numbers"
   "Alpha-page-numbers"
   "Appendix-page-numbers"
   "see" ))

I can show you the difference between the result from makeindex (the first column) and the result from xindy (the second column). We only need to eliminate the group letters, that's default option in xindy. It can be done by redefining markup for the letter group.

I enclose an example, how to process the file and a preview of pages 2 and 3.

I processed that file by these four commands:

makeindex mal-sorting.idx

lualatex mal-sorting.tex

[Tex/LaTex] Applying \lowercase to index entries

I'd say that

\newcommand*{\AddIndexEntry}[2]{%
    % #1 = indexed term, #2 = word to index this under
    \par\noindent
    \lowercase{\def\temp{#2}}%
    Indexing: #2%
    \expandafter\index\expandafter{\temp!#1}%
}

should be what you need.

How does \lowercase works? It sends its argument to a further processor (it's not a macro, so it doesn't its work in TeX's “mouth”); the token list is converted using the \lccode table: each character token that hasn't a zero \lccode is converted to its lowercase correspondent, but symbolic tokens such as \def or \temp are untouched. The token list so obtained is put back in the input as if it had been there from the beginning. There's no expansion during this process: so if TeX finds \lowercase{\def\temp{Xyz}} when it's executing things, then it "waits" a bit, processes the token list as explained, then it processes

\def\temp{xyz}

and goes along.

In case you have more than one index, you can use a modified form:

\documentclass{article}
\usepackage{imakeidx}

\newcommand*{\AddIndexEntry}[3][]{%
  % #1 = indexed term, #2 = word to index this under
  \par\noindent
  \lowercase{\def\temp{#3}}%
  Indexing: #3%
  \if!#1!
    \expandafter\index\expandafter{\temp!#2}%
  \else
    \expandafter\indexopt\expandafter{\temp!#2}{#1}
  \fi
}
\newcommand{\indexopt}[2]{\index[#2]{#1}}

\makeindex
\makeindex[name=Name,title=Title,columns=1]

\begin{document}

\AddIndexEntry{aardvark}{aardvark}
\AddIndexEntry{Saved by Zero}{Saved}
\AddIndexEntry{Saved by Zero}{Zero}
\AddIndexEntry[Name]{zero}{zero}

\printindex
\printindex[Name]

\end{document}

The \indexopt macro takes care of switching the arguments, so that the \expandafter doesn't need to jump over the optional argument to \index.

[Tex/LaTex] Sorting index entries with accented words

Here's the simple solution. Well, not so simple, after all. :)

One small problem, that I'll solve in a next release of imakeidx: for some reason (that I don't remember now) we decided that program=xindy called texindy anyway. But unfortunately, it seems that the calls

xindy -M mystyle -C utf8 -L portuguese words.idx

and

texindy -M mystyle -C utf8 -L portuguese words.idx

are not equivalent, as the latter throws up an incomprehensible error (probably a bug in the texindy script).

Thus the following document will require to run manually xindy (but you have Arara, so it's not a problem), until the small problems are corrected.

Notice that xindy provides two commands for the letter groups, which should be redefined in the preamble to do what's wanted.

\begin{filecontents*}{mystyle.xdy}
(markup-locclass-list :open "\dotfill " :sep "\dotfill ")
\end{filecontents*}

\documentclass{memoir}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{imakeidx}[2012/05/09]
\newcommand*{\lettergroupDefault}[1]{}
\newcommand*\lettergroup[1]{%
  \par\textit{#1}\par
  \nopagebreak
  }

\def\pfill{\unskip~\dotfill\penalty500 
  \strut\nobreak\dotfil~\ignorespaces}

\def\efill{\hfill\nopagebreak}

\def\dotfil{\leaders\hbox to.6em{\hss.\hss}\hfil}

\makeindex[name=words,columns=1,program=xindy,options=-M texindy -M mystyle -C utf8 -L portuguese]
\begin{document}

Hello world.

\index[words]{abacate}
\index[words]{ábaco}
\index[words]{alavanca}
\index[words]{árvore}
\index[words]{arte}
\index[words]{ácaro}
\index[words]{aba}

\printindex[words]
