% \iffalse meta-comment % vim: textwidth=75 %<*internal> \iffalse % %<*readme> --- author: - Robert Alessi title: 'The icite package – README file' --- Overview ======== `icite` is designed to produce from BibTeX or BibLaTeX bibliographical databases the different indices of authors and works cited which are called _indices locorum citatorum_. It relies on a specific `\icite` command and can operate with either BibTeX or BibLaTeX.

Run `'latex icite.ins'` to produce the `icite.sty` file; 2. To finish the installation you have to move the `icite.sty` file into a directory where LaTeX can find them. See the FAQ on `texfaq.org` at for more on this. Development, Git Repository =========================== Browse the code --------------- You can browse icite repository on the web: From this page, you can download all the releases of `icite`. For instructions on how to install `icite`, please see above. Comments, Feature requests, Bug Reports --------------------------------------- Download the repository ----------------------- `icite` development is facilitated by git, a distributed version control system. You will need to install git (most GNU/Linux distributions package it in their repositories). Use this command to download the repository git clone http://git.robertalessi.net/icite A new directory named icite will have been created, containing `icite`. Git hosting ----------- Make an account on and navigate (while logged in) to . Click *Fork* and you will have in your account your own repository of `icite` where you will be able to make whatever changes you like to. % %<*internal> \fi \def\nameofplainTeX{plain} \ifx\fmtname\nameofplainTeX\else \expandafter\begingroup \fi % %<*install> \input docstrip.tex \keepsilent \askforoverwritefalse \preamble Copyright (C) 2019 by Robert Alessi Please send error reports and suggestions for improvements to Robert Alessi This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

However, by % default, only the authors and the works cited are inserted in the % index. Furthermore, authors and works are indexed separately and % only inserted in the global index that is generated by % \cs{makeindex}. Another limitation is that the references are also % excluded from the index. % % Notwithstanding these limitations, it is quite possible to typeset % \emph{indices locorum citatorum} with Bib\LaTeX, but this remains an % intricate business and requires knowing how to redefine and/or patch % standard and internal Bib\LaTeX\ commands. % % The \package{icite} package is but a modest piece of software which % addresses this situation. It relies on citation commands, but does % not require Bib\LaTeX. Instead, \hologo{BibTeX} can be used as % \package{icite} uses the \package{usebib} % package\footnote{\cite{usebib}} to build the indices by drawing % directly from the bibliographical database. % % % \section[The \package{icite} package]{The \textsf{icite} package} % The \package{icite} package is loaded as usual like so:--- % \iffalse %<*example> % \fi \begin{code} \usepackage[]{icite} \end{code} % \iffalse % % \fi % % \package{icite} may be loaded with two optional \enquote*{named % arguments} either of which is set using the syntax % \meta{key}$=$\meta{value}. The description of the optional arguments % follows:--- % % \DescribeOption{citecmd}\label{ref:citecmd} % |citecmd|$=$\meta{command}\hfill\tcboxverb{Default: cite}\\ % \meta{command} may be any citation command accepted by % \hologo{BibTeX} or Bib\LaTeX. This option is used by the \cs{icite} % command that is described below. By default, \cs{icite} uses the % \cs{cite} command to insert citations in the body text. % % \DescribeOption{defaultindex} % |defaultindex|$=$|none|\verb+|+\meta{index\_name}\hfill% % \tcboxverb{Default: not set}\\ % \meta{index\_name} is the name of the index in which all passages % cited with the \cs{icite} command are to be found by default. As % this option is not initally set, \cs{icite} naturally inserts cited % passages in the default general index, unless |defaultindex| is set % to the value |none|, in which case indexing is disabled. It must be % noted that this named argument does not need a value as it defaults % to |loccit| if it is used alone. This is an easy way to have all % passages cited indexed in a separate index named |loccit|. % % \DescribeOption{nobibengine}\NEWfeature{v1.1} % \changes{v1.1}{2019/03/12}{New global option \texttt{nobibengine}}% % |nobibengine|$=$|true|\verb+|+|false|\hfill% % \tcboxverb{Default: not set}\\ % This named argument does not need a value as it defaults to |true| % if it is used. When this option is activated, \package{icite} does % not use \hologo{BibTeX} or Bib\LaTeX\ to insert the citations in the % body text---even if either is loaded in the preamble---and pulls the % necessary information directly from the bibliographical % database. For this reason, \cs{bibinput} described below is of % course still required. The citations inserted consist of the % elements described below \vref{sec:entry-fields} % \vpageref{sec:entry-fields}. However, it must be noted that if the % entry field |shorthand| of any author/work be set in the database, % it takes precedence over the fields used to define author names and % titles. % % \paragraph{Bibliographical database} % \DescribeMacro{\bibinput} Once \package{icite} is loaded, it must be % connected to at least one bibliographic |.bib| file. To that end, % \package{icite} uses the same \cs{bibinput} command as % \package{usebib}.\footnote{Please refer to \cite[1]{usebib} for % more detailed information on how to use this command.} An example % follows:--- % % \iffalse %<*example> % \fi \begin{code} % load icite, have \icite use \autocite by default, and insert cited % passages in a separate index named 'loccit': \usepackage[citecmd=autocite, defaultindex]{icite} % note that the .bib file must be stripped of its extension: \bibinput{bibliography} % that is: load bibliography.bib \end{code} % \iffalse % % \fi % % \subsection{Preamble-only commands} % The following commands may be found in the preamble only. % \paragraph{Styling the titles} % \DescribeMacro{\SetTitleStyle} By default, \package{icite} prints % the titles of the works cited in italics.\\ % \cs{SetTitleStyle}\marg{formatting directives} can be used in the % preamble only to customize the way titles are displayed in the % indices, like so:--- % % \iffalse %<*example> % \fi \begin{code} \SetTitleStyle{\textbf{#1}} \end{code} % \iffalse % % \fi % As this example shows, |#1| is the token that is replaced with the % actual title in the formatting directives of the \cs{SetTitleStyle} % command. % % \paragraph{Delimiters} % \NEWfeature{v1.2}\DescribeMacro{\AuthorTitleDelim} % \cs{AuthorTitleDelim}\marg{delimiter} sets the delimiter between % authors and titles in the body text when the |nobibengine| option is % set to |true|. The default delimiter is a comma and a space. % % \DescribeMacro{\TitlePageDelim} % \cs{TitlePageDelim}\marg{delimiter} sets the delimiter between % titles and pages in the body text when the |nobibengine| option is % set to |true|. The default delimiter is a comma and a space. % % \subsection[\textsf{icite} for the Impatient]% % {\package{icite} for the Impatient} % Read \href{samples/icite-minimal.pdf}{\texttt{icite-minimal.pdf}}. % % \subsection{Entry fields} % \label{sec:entry-fields} % \subsubsection{Author names} % To process author names, \package{icite} uses the following entry % fields: % \begin{description} % \item[author] As for example in |author = {Ullmann, Manfred}|, which % is satisfactory in most cases. % \item[indexauthor] This field is not set by Bib\LaTeX. However, it % may be used as a fallback field for multiple or complex names. % \item[sortname] This standard Bib\LaTeX\ which is never printed may % be used to modify the sorting order of the index entries. % \end{description} % % \paragraph{Example} % From a given entry such as: \\[1ex]% % |author = {|\prname{.hunayn ibn 'is.hAq al-`ibAdiyy, 'abU % zayd}|}|\\[1ex]% % it may prove useful to define an additional |indexauthor| field to % have printed in the index only the relevant part of the name, like % so: \\[1ex]% % |indexauthor = {|\prname{.hunayn ibn 'is.hAq}|}| or % |indexauthor = {|\prname{.hunayn}|}|\\[1ex] % But in the end, the |sortname| field is also needed because the % diacritics must be discarded so that the name be sorted % properly:\\[1ex]% % |sortname = {|Hunayn ibn Ishaq|}| % % \subsection{Titles} % To process titles, \package{icite} uses the following entry fields: % \begin{description} % \item[title] The full title of the work. % \item[shorttitle] The title in an abbriged form. If this entry is % set, it takes precedence over the |title| field in the printed index. % \item[indextitle] This field may be used to have a title such as % \emph{The {\TeX}Book} printed in the index as \emph{{\TeX}Book, The}. % \item[indexsorttitle] Like |sortname| for author names, this field is % used for sorting only and is never printed. From the previous % example, it may be used like so: \\% % |indexsorttitle = {TEXBook}| % \end{description} % % \section{Basic use} % \DescribeMacro{\icite} \package{icite} provides the \cs{icite} % command which both inserts a formatted citation in the body text and % an entry corresponding to the passage cited in the index. This % command is to be used in place of any \hologo{BibTeX} or Bib\LaTeX\ % citation command the syntax of which is % \cs{command}\oarg{pre}\oarg{post}\marg{key}. It must be noted that % only standard citation commands are supported, with the exception of % those mentioned as qualified citation lists or so-called % \enquote*{multicite} commands. The full syntax of \cs{icite} % follows:--- % % \iffalse %<*example> % \fi \begin{code} \icite[
][]{}[]
\end{code}
% \iffalse
%
% \fi
% Where \oarg{command} can be used as a further optional argument to
% specify a standard citation command that \cs{icite} should emulate
% instead of the default \cs{cite} command or any other command set as
% default in the preamble by means of the |citecmd| global
% option.\footnote{See above, \vref{ref:citecmd}.}
%
% \paragraph{Example} The following example illustrates how
% \package{icite} can be used in combination with Bib\LaTeX\ and the
% \package{imakeidx} package to have the passages cited sorted and
% printed in a separate, specific \enquote*{Index of Passages
% Cited}:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  % preamble
  % load icite, have \icite use \autocite by default, and insert cited
  % passages in a separate index named 'loccit':
  \usepackage[citecmd=autocite, defaultindex]{icite}
  % load bibliography.bib
  \bibinput{bibliography}

 % load biblatex (with oxnotes, \autocite acts as \footcite)
 \usepackage[style=oxnotes]{biblatex}
 \addbibresource{bibliography.bib} % mind the extension here

 % load imakeidx and use xindy to have the numbers sorted properly
 \usepackage[xindy]{imakeidx}
 \makeindex[name=loccit, title=Index of Passages Cited (modern authors)]
\end{code}
% \iffalse
%
% \fi
%
% Then \cs{icite} can be used like so:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  \section*{\cs{icite} in action}
  Let us start with four citations of the same reference, to make sure
  that they are all indexed and sorted properly:
  one\icite[123]{Ullmann1970}, two\icite[231]{Ullmann1970},
  three\icite[81]{Ullmann1970} and four\icite[18]{Ullmann1970}.

  three\icite[205]{Bürgel2016} and four\icite[380]{Dols1987}.

  Finally, let us have \cs{icite} use \cs{textcite} to cite

% 
% All indices and the contents of the \hologo{BibTeX} file that has
% been used can be found below in the appendix
% (\vrefrange{ref:indices}{ref:icite-bib} respectively). As can be
% seen by comparing the bibliography generated in the footnotes with
% the text printed in the index, \package{icite} prints as expected
% the abbridged forms of the titles when they are
% available. Furthermore, as a default citation command set in the
% preamble, the \enquote*{oxnotes} Bib\LaTeX\ option of
% \package{biblatex-oxref} style package makes \cs{autocite} behave
% like \cs{footcite}. Finally, the page numbers in the index are
% sorted properly: for example, two-digit numbers, like 81, are listed
% before 123.
%
% \section{Refined use}
% When references are made not only to modern authors but also to
% authors and works from classical antiquity or from the Middle Ages,
% it is commonly agreed that at least two separate indices of passages
% cited should be made. Another option is not to index passages cited
% from modern authors at all.
%
% \DescribeMacro{\IndexSubtypeAs} \package{icite} is able to
% differentiate between sources by drawing from the bibliographical
% database the exact string that may be found in the |entrysubtype|
% entry field. To that end, the \cs{IndexSubtypeAs} command is
% provided. It takes to mandatory arguments, like so:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  \IndexSubtypeAs{}{}
\end{code}
% \iffalse
%
% \fi
% Where || is any given string used to specify an
% |entrysubtype| in the bibliographical database, and ||
% the name of the index which the authors matching that subtype must
% go into. This command is to be found in the preamble only.
%
% Of course different subtypes can be associated with a single index
% or with different indices. That said, one should keep in mind that
% any entry the actual subtype of which is not associated with an
% index is processed as if it had no subtype at all. Examples
% follow:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  % load icite, and have cited authors indexed in an index named
  % 'secondary':
  \usepackage[defaultindex=secondary]{icite}
  % except for authors whose 'entrysubtype' field matches the string
  % 'classical': have them indexed in an index named 'primary':
  \IndexSubtypeAs{classical}{primary}
  % authors whose 'entrysubtype' field matches the string 'medieval'
  % should go into the same index:
  \IndexSubtypeAs{medieval}{primary}
\end{code}
% \iffalse
%
% \fi
% Or:
% \iffalse
%<*example>
% \fi
\begin{code}
  % load icite, but do not index passages cited with \icite:
  \usepackage[defaultindex=none]{icite}
  % except for authors whose 'entrysubtype' field matches the string
  % 'classical': have them indexed in an index named 'primary':
  \IndexSubtypeAs{classical}{primary}
  % authors whose 'entrysubtype' field matches the string 'medieval'
  % should go into the same index:
  \IndexSubtypeAs{medieval}{primary}
\end{code}
% \iffalse
%
% \fi
%
% \paragraph{Example} In the following example, modern authors, namely
% those whose |entrysubtype| field does not match the string
% |classical| should go into the default |loccit| index. As for those
% whose |entrysubtype| matches |classical|, they should to into an
% index named |primary|. \label{ref:classics-pkg}Furthermore, the
% \package{classics} package is used to format references in which a
% volume number is used.\footnote{For more information, see below
% \vref{sec:classics-usage}.} In this way, \package{xindy} only has

% \label{sec:classics-usage}
% As said above \vpageref{ref:classics-pkg}, it is advisable to use
% the \package{classics} package to format volume, page, column, line
% numbers and the like which are inserted in the \meta{post} optional
% argument of the \cs{icite} command\autocite{classics}. An example of
% using \package{classics} to format references to Aristotle according
% to Bekker pagination follows:\footnote{See \cite[2]{classics} for
% more information.}--- %

\begin{example}
  In \emph{Politics}, Aristotle says that man is by nature a political
  animal in the following passages: \aristotle{1253}[a][2--9] (Book~1)
  and again in \aristotle{1278}[b][19] (Book~3). The latter passage
  shows that one should read the whole section of Book~1 concerning
  household management and the control of slaves
  (\aristotle*{1253}[b][1]{1253}[b][39]).
\end{example}
% \iffalse
%
% \fi
% The following prints the same body text while using \package{icite}
% to have the passages cited inserted in the \emph{Index locorum
% citatorum} (see below \vref{sec:index-loc-cit}):--- %
% \iffalse

% \fi
\begin{example}
  In \emph{Politics}, Aristotle says that man is by nature a political
  animal in the following passages:
  \icite[\aristotle{1253}[a][2--9]]{Aristotle:Politica}[notecite]
  (Book~1) and again in \icite[\aristotle{1278}[b][19]]%
  {Aristotle:Politica}[notecite] (Book~3). The latter passage shows
  that one should read the whole section of Book~1 concerning
  household management and the control of slaves
  \icite[\aristotle*{1253}[b][1]{1253}[b][39]]%
  {Aristotle:Politica}[pnotecite].
\end{example}
% \iffalse
%
% \fi
% As can be seen, the \cs{notecite} and \cs{pnotecite} commands have
% been used to insert only the references in the body text.
%
% It is also advisable to use \package{xindy} to compile indices of
% passages cited because \package{xindy}, unlike \package{makeindex}
% or \package{xindex}, is able to sort numbers properly: for example,
% with \package{xindy}, such a number as 81 will come before 100, but
% will be sorted after 100 with the other two engines.
% \begin{tcblisting}{text only, title=Caveat}
%   \package{xindy} (actually |texindy|) is also designed to ignore
%   \TeX\ commands by default. However, due to a missing line in
%   |xindy/modules/base/tex.xdy|,\footnote{As the time of writing, in
%   \package{xindy} v2.5.1.} this does not apply to so-called
%   \enquote*{starred} \TeX\ commands, such as \cs{aristotle*} from
%   the example above.
% \end{tcblisting}
% One easy way to get around this issue is to create a style file with
% a single line that instructs \package{xindy} to ignore the asterisk
% when processing the index, like so:--- %
% \iffalse
%<*example>
% \fi
\begin{tcblisting}{minted language=lisp, listing only, title=icite.xdy}
  (merge-rule "\*" "" :eregexp)
