%
% \section{Introduction}
% In comparison to Prof. Lagally's outstanding Arab\TeX,\footnote{See
% \url{http://ctan.org/pkg/arabtex}} Arab{\LuaTeX} is at present
% nothing more than a modest piece of software. Hopefully---if I may
% say so---it will eventually provide all of its valuable qualities to
% the {\LuaLaTeX} users.
%
% \package{arabtex} dates back to 1992. As far as I know, it was then
% the first and only way to typeset Arabic texts with \TeX\ and
% \LaTeX. To achieve that, \package{arabtex} provided---and still
% does---an Arabic font in \arb[trans]{\uc{nasxI}} style and a macro
% package that defined its own input notation which was, as the author
% stated, \enquote{both machine, and human, readable, and suited for
% electronic transmission and e-mail
% communication}.\footnote{\textcite[2]{pkg:arabtex}.}  Even if the
% same can be said about Unicode, Arab\TeX\ \textsc{ASCII} input
% notation still surpasses Unicode input, in my opinion, when it comes
% to typesetting complex documents, such as scientific documents or
% critical editions where footnotes and other kind of annotations can
% be particulary abundant. It must also be said that most text editors
% have trouble in displaying Arabic script connected with preceding or
% following \LaTeX\ commands: it often happens that commands seem
% misplaced, not to mention punctuation marks, or opening or closing
% braces, brackets or parentheses that are unexpectedly displayed in
% the wrong direction. Of course, some text editors provide ways to
% get around such difficulties by inserting invisible Unicode
% characters, such as LEFT-TO-RIGHT or RIGHT-TO-LEFT MARKS
% (\texttt{U+200E}, \texttt{U+200F}), RTL/LTR \enquote{embed}
% characters (\texttt{U+202B}, \texttt{U+202A}) and RLO/LRO
% \enquote{bidi-override} characters (\texttt{U+202E},
% \texttt{U+202D}).\footnote{Gáspár Sinai's Yudit probably has the
% best Unicode support. See \url{http://www.yudit.org}.} Nonetheless,
% it remains that inserting all the time these invisible characters in
% complex documents rapidly becomes confusing and cumbersome.
%
% The great advantage of Arab\TeX\ notation is that it is immune from
% all these difficulties, let alone its being clear and
% straightforward. One also must remember that computers are designed
% to process code. Arab\TeX\ notation is a way of encoding Arabic
% language, just as \TeX\ \enquote{mathematics mode} is a way of
% processing code to display mathematics. As such, not only does it
% allow greater control over typographical features, but it also can
% be processed in several different ways: so without going into
% details, depending on one's wishes, Arab\TeX\ input can be full
% vocalized Arabic (\emph{scriptio plena}), vocalized Arabic or
% non-vocalized Arabic (\emph{scriptio defectiva}); it further can be
% transliterated into whichever romanization standard the user may
% choose.
%
% \label{ref:tei-to-come}
% But there may be more to be said on that point, as encoding Arabic
% also naturally encourages the coder to vocalize the texts---without
% compelling him to do so, of course. Accurate coding may even have
% other virtuous effects. For instance, hyphens may be used for tying
% particles or prefixes to words, or to mark inflectional endings, and
% so forth. In other words, accurate coding produces accurate texts
% that can stand to close grammatical scrutiny and to complex textual
% searches as well.
%
% Having that in mind, I started \package{arabluatex}. With the help
% of Lua, it will eventually interact with some other packages yet to
% come to produce from \verb|.tex| source files, in addition to
% printed books, \texttt{TEI xml} compliant critical editions and/or
% lexicons that can be searched, analyzed and correlated in various
% ways.
%
%\subsection{\package{arabluatex} is for {\LuaLaTeX}}
% It goes without saying that \package{arabluatex} requires
% {\LuaLaTeX}. \TeX\ and \LaTeX\ have \package{arabtex}, and
% {\XeLaTeX} has \package{arabxetex}. Both of them are much more
% advanced than \package{arabluatex}, as they can process a number of
% different languages,\footnote{\label{fn:arabtex-languages}To date,
% both packages support Arabic, Maghribi, Urdu, Pashto, Sindhi,
% Kashmiri, Uighuric and Old Malay; in addition to these,
% \package{arabtex} also has a Hebrew mode, including Judeo-Arabic and
% Yiddish.} whereas \package{arabluatex} can process only Arabic for
% the time being. More languages will be included in future releases
% of \package{arabluatex}.
%
% In comparison to \package{arabxetex}, \package{arabluatex} works in
% a very different way. The former relies on the
% \href{http://scripts.sil.org/TECkitIntro}{\texttt{TECkit}} engine
% which converts Arab\TeX\ input on the fly into Unicode Arabic
% script, whereas the latter passes Arab\TeX\ input on to a set of Lua
% functions. At first, \LaTeX\ commands are taken care of in different
% ways: some, as \cs{emph}, \cs{textbf} and the like are expected to
% have Arabic text as arguments, while others, as \cs{LR}, for
% \enquote{left-to-right text}, are not. Then, once what is Arabic is
% carefully separated form what is not, it is processed by other Lua
% functions which rely on different sets of correpondence tables to do
% the actual conversion in accordance with one's wishes. Finally, Lua
% returns to \TeX\ the converted strings---which may in turn contain
% some other Arab\TeX\ input yet to be processed---for further
% processing.
%
% \section{The basics of \package{arabluatex}}
% \subsection{Activating \package{arabluatex}}
% \package{arabluatex} is loaded the usual way:\\
% \tcboxverb{\usepackage{arabluatex}}\\
% The only requirement of \package{arabluatex} is {\LuaLaTeX};
% it will complain if the document is compiled with another
% engine. That aside, \package{arabluatex} does not load packages such
% as \package{polyglossia}. Although it can work with
% \package{polyglossia}, it does not require it.
%
% \paragraph{Font setup}
% Any Arabic font can be defined to be used with
% \package{arabluatex}. For example, assuming that \package{fontspec}
% is loaded, this line may be inserted in the preamble, just above the
% line that loads \package{arabluatex}:
% \arabluabox{\cs{newfontfamily}\cs{arabicfont}\marg{fontname}[Script=Arabic]}
% \noindent where \meta{fontname} is the standard name of the Arabic
% font to be used.
%
% By default, if no Arabic font is selected, \package{arabluatex} will
% issue a warning message and attempt to load the Amiri
% font\footnote{\textcite{pkg:amiri}.} like so:---\\
% \tcboxverb{\newfontfamily\arabicfont{Amiri}[Script=Arabic]}
% \begin{quoting}
%   \textsc{Rem.} By default Amiri places the \arb[trans]{kasraT} in
%   combination with the \arb[trans]{ta^sdId} below the consonant,
%   like so: \arb{BBi}\,. That is correct, as at least in the oldest
%   manuscripts {\renewfontfamily\arabicfont{Amiri}[Script=Arabic,
%   RawFeature={+ss05}]\arb{BBi}} may stand for \arb{BBa} as
%   well as \arb{BBi}\,. See \textcite[i. 14 C--D]{Wright}. The placement
%   of the \arb[trans]{kasraT} above the consonant may be obtained by
%   selecting the |ss05| feature of the Amiri font, like
%   so:---\footnote{See the documentation of \package{amiri},
%   \textcite[6]{pkg:amiri}.}\\
%   \tcboxverb{\newfontfamily\arabicfont{Amiri}[Script=Arabic,RawFeature={+ss05}]}
%
%   Other Arabic fonts may behave differently.
% \end{quoting}
%
% \subsection{Options}
% \label{sec:options}
% \package{arabluatex} may be loaded with five global options, the
% first four of which are mutually exclusive and may be overriden at
% any point of the document (see below \vref{sec:local-options}):
% 
% \DescribeOption{voc}\hfill\tcboxverb{Default}\\ In this mode,
% which is the one selected by default, every short vowel written
% generates its corresponding diacritical mark: \arb[trans]{.dammaT}
% (\arb{Bu}), \arb[trans]{fat.haT} (\arb{Ba}) and \arb[trans]{kasraT}
% (\arb{Bi}). If a vowel is followed by |N|, viz. \meta{uN, aN, iN},
% then the corresponding \arb[trans]{tanwIn} (\arb{BuN}, \arb{B|aN}\,,
% \arb{TaN}, \arb{BaN_A} or \arb{BiN}) is generated. Finally, \meta{u,
% a, i} at the commencement of a word indicate a \enquote{connective
% \arb[trans]{'alif}\,} (\arb[trans]{'alifu 'l-wa.sli}), but |voc|
% mode does not show the \arb[trans]{wa.slaT} above the
% \arb[trans]{'alif}; instead, the accompanying vowel may be expressed
% at the beginning of a sentence (\arb{u} \arb{a} \arb{i}).
%
% \DescribeOption{fullvoc}\\ \label{fullvoc-mode}In addition to what
% the |voc| mode does, |fullvoc| expresses the \arb[trans]{sukUn} and
% the \arb[trans]{wa.slaT}.
%
% \DescribeOption{novoc}\\ None of the diacritics is showed in |novoc|
% mode, unless otherwise specified (see \enquote{quoting} technique
% below \vref{sec:quoting}).
%
% \DescribeOption{trans} \\ \label{ref:describe-trans}This mode
% transliterates the Arab\TeX\ input into one of the accepted
% standards. At present, three standards are supported (see below
% \vref{sec:transliteration} for more details):
% \begin{description}
% \item[dmg] \emph{Deutsche Morgenländische Gesellschaft}, which is
%   selected by default;
% \item[loc] \emph{Library of Congress};
% \item[arabica] \emph{Arabica}.
% \end{description}
% More standards will be included in future releases of
% \package{arabluatex}.
%
% \label{ref:export-global-opt}
% \DescribeOption{export} |export|$=$|true|\verb+|+|false|
% \hfill\tcboxverb{Default: false}\\ \label{export-mode}
% \NEWfeature{v.1.13} This option acts as a named argument and does
% not need a value as it defaults to |true| if it is used. It enables
% \package{arabluatex} to produce a duplicate of the original |.tex|
% source file in which all \textsc{ascii} strings are replaced with
% Unicode equivalents. See below \vref{sec:arabtex2utf} for more
% information.
% 
% \subsubsection{Classic contrasted with modern typesetting of Arabic}
% \label{sec:classic-modern-typesetting}
% \NEWfeature{v.1.2} By default, \package{arabluatex} typesets Arabic
% in a classic, traditional style the most prominent features of which
% are the following:
% \begin{itemize}
% \item \enquote*{Classic} \arb[trans]{maddaT}: when
% \arb[trans]{'alif} and \arb[trans]{hamzaT} accompanied by a simple
% vowel or \arb[trans]{tanwIn} is preceded by an \arb[trans]{'alif} of
% prolongation (\arb[voc]{BA}), then a mere \arb[trans]{hamzaT} is
% written on the line, and a \arb[trans]{maddaT} is placed over the
% \arb[trans]{'alif}, like so:---
% \begin{quote}
%   |samA'uN| \arb[voc]{samA'uN} \arb[trans]{samA'uN}, |jA'a|
%   \arb[voc]{jA'a} \arb[trans]{jA'a}, |yatasA'alUna|
%   \arb[voc]{yatasA'alUna} \arb[trans]{yatasA'alUna}\footnote{Note
%   that in old mss. such forms as \arb[voc]{samA"'a"'a},
%   \arb[voc]{jA"'a"'a} are also found; see \textcite[i. 24
%   D]{Wright}.} (see \vpageref{ref:madda} for further details).
% \end{quote}
% \item The euphonic \arb[trans]{ta^sdId} is generated (see
%   \vpageref{ref:euphonic-tashdid}).
% \item In |fullvoc| mode, the \arb[trans]{sukUn} is expressed.
% \item In such words as \arb{^say'aN}, \arb{.zim'aN} and the like,
%   the \arb[trans]{hamzaT} alone is not written over the letter
%   \arb[trans]{yA'} with no diacritical points below as in
%   \arb{^sayy"'aN}, \arb{.zimy"'aN}, but over a horizontal stroke
%   placed in the continuation of the preceding letter. %
% \iffalse
%<*example>
% \fi
\begin{tcblisting}{text only}
  Please note that only few Arabic fonts provide such contrivances. In
  case this feature is not supported by some Arabic font, it is
  advisable to use \cs{SetArbEasy}.
\end{tcblisting}
% \iffalse
%</example>
% \fi
% \end{itemize}
% 
% \DescribeMacro{\SetArbEasy} \NEWfeature{v1.4.4} Such refinements as
% \enquote*{classic} \arb[trans]{maddaT} may be discarded by the
% \cs{SetArbEasy} command, either globally in the preamble or locally
% at any point of the document. The difference between \cs{SetArbEasy}
% and its \enquote*{starred} version
% \DescribeMacro{\SetArbEasy*}\cs{SetArbEasy*} is that the former
% keeps the \arb[trans]{sukUn} that is generated by the |fullvoc|
% mode, while the latter further takes it away. Default
% \enquote*{classic} rules may be set back at any point of the
% document with the \DescribeMacro{\SetArbDflt}\cs{SetArbDflt}
% command. \NEWfeature{v1.6} \DescribeMacro{\SetArbDflt*}Assimilation
% rules laid on \vref{ref:assimilation} may also be applied by the
% \enquote*{starred} version of this command \cs{SetArbDflt*} either

% the default option), |fullvoc|, |novoc| and |trans|. Whatever choice
% has been made globally, it may be overriden at any point of the
% document, as the \cs{arb} command may take any of the |voc|,
% |fullvoc|, |novoc| or |trans| modes as optional argument, like
% so:---
% \begin{itemize}
% \item \DescribeOption{voc} \cs{arb}|[voc]|\marg{Arabic text};

% \item \DescribeOption{trans} \cs{arb}|[trans]|\marg{Arabic text}.
% \end{itemize}
%
% The same optional arguments may be passed to the environment |arab|:
% one may have \cs{begin}|{arab}|\oarg{mode}|...|\cs{end}|{arab}|,
% where \meta{mode} may be any of |voc|, |fullvoc|, |novoc| or

% \begin{quoting}
%   \textsc{Rem.}~\emph{a.} Please note that in all cases of elision,
%   the \arb[trans]{'alifu 'l-wa.sli} is expressed only by the vowel
%   that accompanies the omitted \arb[trans]{hamzaT}: \meta{u, a, i}
%   as in |wa-inhazama| \arb[fullvoc]{wa-inhazama}
%   \arb[trans]{wa-inhazama}. For more details on the definite article
%   and the \arb[trans]{'alifu 'l-wa.sli} see
%   \vref{ref:definite-article}.
%
%   That said, \arb{.A} as a consonant is actually the \emph{spiritus
%   lenis} of the Greeks and is distinguished by the
%   \arb[trans]{hamzaT} \arb[novoc]{(|"')} as it is shown in the above
%   table. However, the bare \arb[trans]{'alif} may also be encoded as
%   |.A| whether it be followed by a vowel or not, like so: |wa-.An|
%   \arb{wa-.An} \arb[trans]{wa-.An} (where the dot symbolizes the
%   absence of vowel), |wa-.Aan| \arb{wa-.Aan} \arb[trans]{wa-.Aan},
%   |wa-.Ain| \arb{wa-.Ain} \arb[trans]{wa-.Ain}.
%   
%   \textsc{Rem.}~\emph{b.} The letter \arb[novoc]{y} with two points
%   below, \arb{al-yA'u 'l-mu_tannATu min ta.hti-hA}, may also be
%   written without diacritical points as \arb[novoc]{Y}. When it is
%   used as a consonant, it is encoded |aY|, where |a| recalls the
%   \arb[trans]{fat.haT} placed above the preceding letter in
%   vocalized Arabic, like so: |qaY'uN| \arb{qaY'uN}
%   \arb[trans]{qaY'uN}, |^saY'uN| \arb{^saY'uN} \arb[trans]{^saY'uN},
%   |^saY'aN| \arb[trans]{^saY'aN} \arb{^saY'aN}.
%
%   The same result may be achieved by encoding this letter as |.y|,
%   like so: |qa.y'uN| \arb{qa.y'uN} \arb[trans]{qa.y'uN}, |^sa.y'uN|
%   \arb{^sa.y'uN} \arb[trans]{^sa.y'uN}, |^sa.y'aN|

% Whether Arabic texts be vocalized or not is essentially a matter of
% personal choice. So one may use |voc| mode and decide not to write
% vowels except at some particular places for disambiguation purposes,
% or use |novoc| mode, not write vowels---as |novoc| normally does not
% show them---except, again,  where disambiguation is needed.\footnote{See
% below \vref{sec:quoting}.}
%
% \iffalse
%<*example>
% \fi
\begin{tcblisting}{text only}
  However, it may be wise to always write the vowels, leaving to the

  showing or not showing the vowels.

% That said, there is no need to write the short vowels
% \arb[trans]{fat.haT}, \arb[trans]{.dammaT} or \arb[trans]{kasraT}
% except in the following cases:---
% \begin{itemize}
% \item at the commencement of a word, to indicate that a connective
% \arb[trans]{'alif} is needed, with the exception of the article (see

% \item when \package{arabluatex} needs to perform a contextual

% \item in the various transliteration modes, as vowels are always

% \subsection{Quoting}
% \label{sec:quoting}
% It is here referred to \enquote{quoting} after the \package{arabtex}
% package.\footnote{See \textcite[22]{pkg:arabtex}} The
% \enquote{quoting} mechanism of \package{arabluatex} is designed to
% be very similar in effect to the one of \package{arabtex}.
%
% To start with an example, suppose one types the following in |novoc|
% mode: \arb[novoc]{`ullima `ilm-a 'l-hay'aT-i}; is it
% \arb[fullvoc]{`ullima}, \emph{he was taught the science of
% astronomy}, or \arb[fullvoc]{`allama}, \emph{he taught the science
% of astronomy}? In order to disambiguate this clause, it may be
% sensible to put a \arb[trans]{.dammaT} above the first \arb[voc]{`}:
% \arb[novoc]{`"ullima `ilm-a 'l-hay'aT-i}, which is achieved by
% \enquote{quoting} the vowel |u|, like so: |`"ullima|, or, with no
% other vowel than the required |u|: |`"ullm|.
%
% This is how the \enquote{quoting} mechanism works: metaphorically
% speaking, it acts as a \emph{toggle switch}. If something, in a
% given mode, is supposed to be visible, \enquote{quoting} hides it;
% conversely, if it is supposed not to, it makes it visible.
%
% As shown above, \enquote{quoting} means inserting one straight
% double quote (|"|) \emph{before} the letter that is to be acted
% upon. Its effects depend on the mode which is currently selected,
% either |novoc|, |voc| or |fullvoc|:---
%
% \paragraph{\texttt{novoc}} In this mode, \enquote{quoting}
% essentially means make visible something that ought not to be so.
% \begin{enumerate}
% \item Quoting a vowel, either short or long, makes the
%   \arb[trans]{.dammaT}, \arb[trans]{fat.haT} or \arb[trans]{kasraT}
%   appear above the appropriate consonant:---
% \begin{quote}
%   |`"ullima| |`ilm-a| |'l-hay'aT-i| \arb[novoc]{`"ullima `ilm-a
%   'l-hay'aT-i} \arb[trans]{`"ullima `ilm-a 'l-hay'aT-i}, |ya.gz"UA|
%   \arb[novoc]{ya.gz"UA} \arb[trans]{ya.gz"UA}.
% \end{quote}
% \item The same applies when \enquote{quoting} the
%   \arb[trans]{tanwIn}:---
% \begin{quote}
%   |wa-'innA| |sawfa| |tudriku-nA| |'l-manAyA| |muqadd"araT"aN|
%   \arb[novoc]{wa-'innA sawfa tudriku-nA 'l-manAyA muqadd"araT"aN},
%   \arb[trans]{wa-'innA sawfa tudriku-nA 'l-manAyA muqadd"araT"aN}.
% \end{quote}
% \item \label{ref:quoted-sukun-b}If no vowel follows the straight
%   double quote, then a \arb[trans]{sukUn} is put above the preceding
%   consonant:---
% \begin{quote}
%   |qAla isma`"| \arb[novoc]{qAla isma`"} \arb[trans]{qAla isma`"},
%   |jA'at"| |hinduN| \arb[voc]{jA'at" \uc{hinduN}}
%   \arb[trans]{jA'at" \uc{hinduN}}, |^sabIhuN| |bi-man| |q"u.ti`at"|
%   |qadamA-hu| \arb[novoc]{^sabIhuN bi-man q"u.ti`at" qadamA-hu}
%   \arb[trans]{^sabIhuN bi-man q"u.ti`at" qadamA-hu}.
% \end{quote}
% \item At the commencement of a word, the straight double quote is
%   interpreted as \arb[trans]{'alif-u 'l-wa.sl-i}:---
% \begin{quote}
%   |wa-"ust"u`mila| \arb[novoc]{wa-"ust"u`mila}
%   \arb[trans]{wa-"ust"u`mila}, |huwa| |"inhazama| \arb[novoc]{huwa
%   "inhazama} \arb[trans]{huwa "inhazama}, |al-"intiqA.d-u|
%   \arb[novoc]{al-"intiqA.d-u} \arb[trans]{al-"intiqA.d-u}.
% \end{quote}
% \end{enumerate}
%
% \paragraph{\texttt{voc}}
% In accordance with the general rule, in this mode, \enquote{quoting}
% makes the vowels and the \arb[trans]{tanwIn} disappear, should this
% feature be required for some reason:---
% \begin{enumerate}
% \item Short and long vowels:---
%   \begin{quote}
%     |q"Ala q"A'iluN| \arb[voc]{q"Ala q"A'iluN} \arb[trans]{q"Ala
%     q"A'iluN}, |ibn-u 'abI 'u.saybi`aT-"a| \arb[voc]{ibn-u 'abI
%     'u.saybi`aT-"a} \arb[trans]{\uc{ibn-u} \uc{'abI}
%     \uc{'u.saybi`aT-"a}}.
%   \end{quote}
% \item \arb[trans]{tanwIn}:---
%   \begin{quote}
%     |madInaT"aN| \arb[voc]{madInaT"aN} \arb[trans]{madInaT"aN},
%     |bAb"aN| \arb[voc]{bAb"aN} \arb[trans]{bAb"aN}, |hud"aN_A|

%     \arb[voc]{^say'"iN} \arb[trans]{^say'"iN}.
%   \end{quote}
% \end{enumerate}
% One may more usefully \enquote{quote} the initial vowels to write
% the \arb[trans]{wa.slaT} above the \arb[trans]{'alif} or insert a
% straight double quote after a consonant not followed by a vowel to
% make the \arb[trans]{sukUn} appear:---
% \begin{enumerate}
% \item \arb[trans]{'alif-u 'l-wa.sl-i}:---
%   \begin{quote}
%     |fI "istiq.sA'-iN| \arb[voc]{fI "istiq.sA'-iN} \arb[trans]{fI

%
% As one can see from \vref{tab:quoted-hamza}, the carrier of the

% \end{quote}
%
% \subsection{\texorpdfstring{The \enquote*{pipe} character
% (\textbar)}{The ‘pipe’ character (\textbar)}}
% \label{sec:pipe}
% In the terminology of Arab\TeX, the \enquote{pipe} character
% \enquote*{\textbar} is referred to as the \enquote{invisible
% consonant}. Hence, as already seen above in
% \vref{sec:quoting-hamza}, its usage to encode the
% \arb[trans]{hamzaT} alone, with no carrier: \verb+|"'+
% \arb[novoc]{|"'}.
%
% Aside from that usage, the \enquote{pipe} character is used to
% prevent almost any of the contextual analysis rules that are
% described above from being applied. Two examples have already been
% given to demonstrate how that particular mechanism works in
% \vref{fn:pipe-allah-01} and in \vref{fn:pipe-madda}. One more example
% follows:---
% \begin{quote}
%   \verb+bi-qrAn|nUn-a+ \arb[voc]{\uc{bi-qrAn|nUn-a}}
%   \arb[trans]{\uc{bi-qrAn|nUn-a}}, \enquote{in Crannon} (Thessaly,
%   Greece).\footnote{See more context \vpageref{ref:qrannun-full}.}
% \end{quote}
% As one can see, the \enquote{pipe} character between the two
% \meta{n} prevents the necessary \arb[trans]{ta^sdId} rule
% (\cpageref{ref:necessary-tashdid}) from being applied.
%
% \subsection{Putting back on broken contextual analysis rules}
% \label{sec:arbnull}
% \NEWfeature{v1.7} In complex documents such as critical editions
% where footnotes and other kind of annotations can be particularly
% abundant, the contextual analysis rules that are described above may
% be broken by \LaTeX\ commands. To take an example, consider the
% following:---%
% \iffalse
%<*example>
% \fi
\begin{example}
  This is wrong:
  \begin{arab}[fullvoc]
    fa-lammA ra'aW\LRfootnote{A footnote which interferes with
      the contextual analysis.} 'l-na^gma...
  \end{arab}
\end{example}
% \iffalse
%</example>
% \fi%
% According to the rule stated \vpageref{sec:diphthong-alif}, the
% diphthong in \arb[trans]{ra'aW} must be resolved into two simple
% vowels before the \arb[trans]{'alif-u 'l-wa.sl-i}, as
% \arb[fullvoc]{ra'aW 'l-na^gma}.
%
% \DescribeMacro{\arbnull} The \cs{arbnull} command is provided so as
% to put back on contextual analysis rules in such situations. It
% takes as argument the word that must be brought back for any given
% rule to be applied as it ought to. Depending on the contexts that
% have to be restored, \cs{arbnull} may be found just after or before
% Arabic words.%

% \subsection{Arabic emphasis}
% \label{sec:emphasis}
% As already seen in \vref{sec:abjad}, the \arb[trans]{'abjad} numbers
% are distinguished from the surrounding words by a stroke placed
% over them. This technique is used to distinguish further words that
% are proper names or book titles.
%
% \DescribeMacro{\aemph} One may use the \cs{aemph}\marg{Arabic
% text} command to use the same technique to emphasize words, like so:---
% \begin{quote}
%   |\abjad{45}:| |kitAbu-hu| |\aemph{fI| |'l-`AdAt-i}|
%   \arb[voc]{\abjad{45}: kitAbu-hu \aemph{fI 'l-`AdAt-i}}
%   \arb[trans]{\abjad{45}: kitAbu-hu \aemph{fI 'l-\uc{`AdAt-i}}}.
% \end{quote}
% 
% \begin{quoting}
%   \textsc{Rem.}~\emph{a.} As the above example shows,
%   \package{arabluatex} places the horizontal stroke \emph{under} the
%   emphasized words in any of the transliteration modes.
%
%   \textsc{Rem.}~\emph{b.} \NEWfeature{v1.9.2}\DescribeMacro{\aemph*}
%   \cs{aemph*} is also provided should one wish to always have the
%   horizontal stroke printed over the emphasized words, like so:
%   |\abjad{45}:| |kitAbu-hu| |\aemph*{fI| |'l-`AdAt-i}|
%   \arb[voc]{\abjad{45}: kitAbu-hu \aemph*{fI 'l-`AdAt-i}}
%   \arb[trans]{\abjad{45}: kitAbu-hu \aemph*{fI 'l-\uc{`AdAt-i}}}.
% \end{quoting}
%
% \subsubsection{Underlining words or numbers}
% \label{sec:underlining}
% \DescribeMacro{\aoline}%
% \DescribeMacro{\aoline*}%
% \DescribeMacro{\auline}%
% \NEWfeature{v1.19}Three additional, non context-sensitive commands
% are provided to distinguish words or numbers:---
% \begin{enumerate}
% \item \cs{aoline}, which is equivalent to \cs{aemph*} described
%   above.
% \item \cs{aoline*}, which is the same as \cs{aoline}, but better
%   suited for \arb[trans]{'ab^gad} numbers.\footnote{See the example
%   provided above \vref{sec:abjad}.}
% \item \cs{auline}, which can be used to underline Arabic words.
% \end{enumerate}
%
% \section{Arabic poetry}
% \label{sec:poetry}
% \NEWfeature{v1.6} \package{arabluatex} provides a special
% environment for typesetting Arabic poetry. Every line in this
% environment must end with |\\|.
%
% \DescribeEnv{arabverse} The |arabverse| environment may take up to
% eight optional \enquote*{named arguments} each of which is set using
% the syntax \meta{key}$=$\meta{value}, like so:---%
% \iffalse
%<*example>
% \fi
\begin{code}
  \begin{arabverse}[key1=value1, key2=value2, ...]
    <verses>
  \end{arabverse}
\end{code}
% \iffalse
%</example>
% \fi
%
% The description of the optional arguments follows:---
%
% \DescribeOption{mode} |mode|$=$\meta{mode}, either |voc|, |fullvoc|,
% |novoc| or |trans|. The default mode is the one that is set at load
% time as already seen \vref{sec:options}.
%
% \DescribeOption{width} |width|$=$\meta{length}
% \hfill\tcboxverb{Default: 0.3\linewidth}\\ The default width of
% each hemistich that the verse consists of. It may be expressed in
% any accepted unit of measurement, such as |4cm| or |2in|. However,
% one must keep in mind that the total length of the two hemistichs
% added to the one of the gutter that separates them must not exceed
% the length of the base line, unless one wishes to have the
% hemistichs distributed on subsequent lines.
%
% \DescribeOption{gutter} |gutter|$=$\meta{width}
% \hfill\tcboxverb{Default: 0.15 x (hemistich width)}\\ The gutter
% consists of the blank space that is between the two hemistichs. By
% default, it is commensurate with the width of the hemistich, but it
% may be expressed in any accepted unit of measurement as well.
%
% \DescribeOption{metre} |metre|$=$\meta{name}
% \hfill\tcboxverb{Default: none}\\ If the name of the metre is
% expressed, it is printed after the lines and set flush left in
% |voc|, |fullvoc| and |novoc| modes or flush right in |trans| mode.
%
% \DescribeOption{delim} |delim|$=$|true|\verb+|+|false|
% \hfill\tcboxverb{Default: false}\\ This named argument does not
% need a value as it defaults to |true| if it is used. If so, a
% delimiter is printed between each of the hemistichs. By default, it
% is set to the \enquote*{star} character \enquote*{*}. The
% \DescribeMacro{\SetHemistichDelim}\cs{SetHemistichDelim}\marg{delimiter}
% command may be used at any point of the document to change this
% default setting.
%
% \DescribeOption{utf} |utf|$=$|true|\verb+|+|false|
% \hfill\tcboxverb{Default: false}\\ As the preceding one, this
% named argument does not need a value as it defaults to |true| if it
% is used. If so, Unicode Arabic input is expected in the |arabverse|
% environment instead of \textsc{ascii} Arab\TeX\ or Buckwalter input
% schemes. See \vref{sec:unicode-input} for more details.
%
% \DescribeOption{color} |color|$=$\meta{color name}
% \hfill\tcboxverb{Default: not set}\\
% \NEWfeature{v1.13} The color in which lines of poetry are to be
% rendered.
%
% \label{ref:poetry-export}
% \DescribeOption{export} |export|$=$|true|\verb+|+|false|
% \hfill\tcboxverb{Default: false}\\
% \NEWfeature{v.1.13} This named argument does not need a value as it
% defaults to |true| if it is used. If |export| is set as a global
% option as well (see above \vpageref{export-mode}), all the lines
% will be converted to Unicode and exported to the external selected
% file. See below \vref{sec:arabtex2utf} for more details.
% 
% \DescribeMacro{\bayt} Inside the |arabverse| environment, each line
% is typeset by the \cs{bayt} command which takes two mandatory
% arguments and may accept one optional
% argument.\footnote{\label{ref:bayt-star}A \enquote*{starred} version
% \cs{bayt*} is also defined. \package{arabluatex} uses it internally
% when \texttt{export} is set to \texttt{true} to instruct some Lua
% functions that lines of poetry have already been processed. That
% aside, \cs{bayt} and \cs{bayt*} do the same, and only \cs{bayt}
% should be used.}  Additionally, every \cs{bayt} command \emph{must}
% be followed with |\\| like so:---%
% \iffalse
%<*example>
% \fi
\begin{tcblisting}{text only}
  \cs{bayt}\marg{\arb[trans]{.sadr}}\oarg{\arb[trans]{tadwIr}}%
  \marg{\arb[trans]{`ajuz}}|\\|
\end{tcblisting}
% \iffalse
%</example>
% \fi
%
% That two subsequent hemistichs should be connected with one another
% is technically named \arb[trans]{tadwIr}. Should that happen, either
% the \arb[trans]{.sadr} or the \arb[trans]{`ajuz} or both of them,
% may be connected to one another by letters that are naturally bound
% to the following or the preceding ones over the
% \arb[trans]{tadwIr}. The optional argument of the \cs{bayt} command
% is designed to deal with the various situations that may arise:---
% \begin{enumerate}
% \item If the two hemistichs be connected with one another by a
% prominent horizontal flexible stroke, the \arb[trans]{ta.twIl} should
% be used, like so: |[--]| (see \vref{sec:tatwil}). Of course, the
% ending word of the \arb[trans]{.sadr} and the word at the
% commencement of the \arb[trans]{`a^guz} must have the
% \arb[trans]{ta.twIl} too so that the proper shapes of the letters be
% selected. Consider for example the following:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \begin{arabverse}[mode=fullvoc, width=.3\linewidth]
    \bayt{lA 'ar_A man `ahidtu fI-hA fa-'abkI 'l---}[--]{---yawma
      dalhaN wa-mA yaruddu 'l-bukA'u}\\
  \end{arabverse}
\end{example}
% \iffalse
%</example>
% \fi%
% As one can see, \emph{triple hyphens} have been used. In the
% \arb[trans]{.sadr}, the first hyphen triggers the rules that are
% related to the definite article and the \arb[trans]{'alif-u
% 'l-wa.sl-i},\footnote{See \vref{ref:definite-article}.} while the
% following two select the figure of the letter \arb[trans]{lAm}
% connected with a following letter. In the \arb[trans]{`a^guz}, the
% last two hyphens select the letter \arb[trans]{yA'} connected with a
% preceding letter, while the first one is simply discarded in this
% mode, but still may appear as it should, if the |trans| mode be
% selected:---%
% \iffalse
%<*example>
% \fi
\begin{example}
  \begin{arabverse}[mode=trans, width=.4\linewidth]
    \bayt{lA 'ar_A man `ahidtu fI-hA fa-'abkI 'l---}[--]{---yawma
      dalhaN wa-mA yaruddu 'l-bukA'u}\\
  \end{arabverse}
\end{example}
% \iffalse
%</example>
% \fi%
% \item In some other cases, it may seem difficult, if not fairly
%   impossible, to split a given word into two parts. This happens
%   mostly because of the \arb[trans]{^saddaT}. Consider for example
%   the following:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \begin{arabverse}[mode=fullvoc, width=.25\linewidth,
    gutter=1cm]
    \bayt{.gayra 'annI qad 'asta`Inu `al_A 'l-ha--}[--mmi ]{'i_dA
      _haffa bi-'l-_tawiyyi 'l-na^gA'u}\\
    \bayt{bi-zaf--UfiN ka-'anna-hA hiq|--laTuN}[ 'ummu ]{ri'AliN
      dawwiyyaTuN saqfA'u}\\
  \end{arabverse}
\end{example}
% \iffalse
%</example>
% \fi%
% In the first line, the word \arb{al-hammi} should be split into
% \arb{al-ham"-- --mi} as the first part of it belongs to the
% \arb[trans]{.sadr} and the second to the \arb[trans]{`a^guz}. One
% solution to avoid splitting this word in such a way is to write
% inside the \arb[trans]{tadwIr} the part of it that belongs to either
% hemistich, without omitting to add a space after it. In the second
% line, the word \arb{'ummu} should be split into \arb{'um"-- --mu},
% so that the only way to avoid splitting it into two parts is to
% write it all inside the \arb[trans]{tadwIr}. In that case, as the
% word is to be placed in the middle, it has been surrounded by
% spaces.
% \end{enumerate}
%
% \paragraph{Scaling and distortion of characters}
% The |arabverse| environment and the \cs{bayt} command are designed
% to typeset the verses in a two-column, fixed width layout. This may
% result in a somewhat distorted text. Should that happen, one may
% adapt the layout by modifying the values of the above described
% |width| and |gutter| named arguments until the visual aspect of the
% layout be satisfactory. It has to be noted that distortion and
% warping may be even more perceptible in Roman than in Arabic
% characters.
%
% \DescribeMacro{\StretchBayt} \cs{StretchBayt}\verb+[true|false]+
% \hfill\tcboxverb{Default: true}\\
% \NEWfeature{v1.20} \cs{StretchBayt} takes one optional argument,
% either |true| or |false| and can be used to remove the stretching
% form lines of Arabic poetry. As a side effect, there will be more
% space between words, but this can be compensated by inserting double
% hyphens between letters (on this technique, see
% \vref{sec:tatwil}). Should it be desired to extend further the
% strokes, four hyphens may be inserted (|----|), viz. a multiple of
% two. \cs{StretchBayt} may be used at any point of the document, even
% between two subsequent lines of poetry. Note that
% \cs{StretchBayt}|[false]| may require to carefuly adjust the width
% of the hemistichs to avoid overlapping.
%
% \paragraph{Footnotes}
% Footnotes are not set by default inside the \cs{bayt} command, but
% there are two easy ways to have them printed.
%
% If they are little in number, each footnote may be split into pairs
% of \cs{footnote\allowbreak{}mark}|{}| (please mind the braces or
% \enquote{declare} |footnotemark| using \cs{MkArbBreak} to take it
% out of the Arabic environment\footnote{See
% \vref{sec:declare-new-commands}.}) in the argument of the \cs{bayt}
% command and \cs{footnotetext} outside the \cs{bayt} command.
%
% If the footnotes are abundant in number, it is advised to load the
% \package{footnotehyper} package which \package{arabluatex} will then
% use to typeset any kind of footnote that is called from the
% arguments of the \cs{bayt} command.\footnote{The \package{footnote}
% package can also be used for the same effect. However, it must be
% loaded \emph{after} \package{arabluatex}.}
%
% \paragraph{Line numbering}
% Inside the |arabverse| environment, the |linenumbers| environment of
% the \package{lineno} package can be used to have the lines of
% succeeding verses numbered. Please refer to the documentation of
% this package for more information or to the example below for a
% basic implementation of this technique.
%

% \vref{ref:assimilation} are applied. See
% \vref{sec:classic-modern-typesetting} for more information. None of

% \paragraph{Brackets}
% \phantomsection
% \NEWfeature{v1.4.3} The various bracket symbols are useful in
% technical documents such as critical editions for indicating that

% to the direction of the text. For the time being, the following
% symbols are supported:
% \begin{itemize}
% \item parentheses: |()|
% \item square brackets: |[]|
% \item angle brackets: |<>|
% \item braces: |{}|
% \end{itemize}
%
% \DescribeMacro{\abraces} Parentheses, square and angle brackets may

% 
% \DescribeMacro{\newarbmark} \NEWfeature{v1.11} \cs{newarbmark} is

% \arabluabox{\cs{newarbmark}\marg{shorthand}\marg{RTL
% codepoint}\marg{LTR rendition}}
%
% As regards the right-to-left codepoint, it may be either typed in
% Unicode or selected as Unicode codepoint. To that end, the \LaTeX\
% command \tcboxverb{\symbol{"XYZT}} or its plain \TeX\ variant
% \tcboxverb{\char"XYZT\relax} may be used, where |XYZT| are
% uppercase hex digits (|0| to |9| or |A| to |F|).
%
% It is also possible to use the so-called `|^^^^| notation' like so:
% \tcboxverb{^^^^xyzt}, where |xyzt| are lowercase hex digits (|0|
% to |9| or |a| to |f|).
%
% As regards the third argument (left-to-right rendition), it may be
% either left empty or typed by means of
% \cs{arb}|[trans]|\marg{arabtex code} so as to have it printed in
% romanized Arabic.%

% As this example shows, \cs{arbcolor} has been used to render
% headings in red with the same encoding both in vocalized and in
% romanized Arabic. The same technique also applies to syllabes inside
% words. \package{arabluatex} takes care of selecting the appropriate
% shape of the letters while coloring them:---
% \begin{quote}\textbf{\enquote*{voc} mode}:\\
%   |i^stara\arbcolor[brown]{y}tu-hu| |bi-_tama\arbcolor[red]{niN}|

% \subsection{Tricks of the trade}
% \label{sec:color-tricks}
% \paragraph{Diacritics}
% Depending on the mode selected, either |voc|, |novoc| or |fullvoc|,
% coloring the diacritics requires more attention for the insertion of
% \cs{arbcolor} may prevent contextual analysis from being applied.
%
% Furthermore, depending on the surrounding letters, the standard
% encoding of short vowels \meta{u, a, i} may result either in
% diacritics or in a connective \arb[trans]{'alif} with the
% \arb[trans]{wa.slaT} or its accompanying vowel. As for the
% \arb[trans]{sukUn}, it is generated by contextual analysis. Thus
% applying colors to bare diacritics requires them to have specific
% encodings.
%
% \Cref{tab:arbcolor-diacritics} gives the Arab\TeX\ equivalents for
% the diacritics to be printed inside or just after \cs{arbcolor}.

% \section{Transliteration}
% \label{sec:transliteration}
% It may be more appropriate to speak of \enquote{romanization} than
% \enquote{transliteration} of Arabic. As seen above in
% \cref{sec:options} \vpagerefrange{sec:options}{sec:local-options},
% the \enquote{transliteration mode} may be selected globally or locally.
%
% This mode transliterates the Arab\TeX\ input into one of the
% accepted standards. As said above \vpageref{ref:describe-trans},
% three standards are supported at present:
% \begin{description}
% \item[dmg] \emph{Deutsche Morgenländische Gesellschaft}, which was
% adopted by the International Convention of Orientalist Scholars in
% Rome in 1935.\footnote{See \textcite{dmg}.} |dmg| transliteration
% convention is selected by default;
% \item[loc] \emph{Library of Congress}: this standard is part of a
%   large set of standards for romanization of non-roman scripts
%   adopted by the American Library Association and the Library of
%   Congress;\footnote{See
%   \url{http://www.loc.gov/catdir/cpso/roman.html} for the
%   \href{http://www.loc.gov/catdir/cpso/romanization/arabic.pdf}{source
%   document concerning Arabic language}.}
% \item[arabica] \NEWfeature{v1.8}
%   \changes{v1.8}{2017/03/30}{\texttt{arabica} transliteration
%   standard is now supported} \emph{Journal of Arabic and Islamic
%   Studies}/\emph{Revue d'études arabes et islamiques}: this standard
%   is most widely used by scholars in the field of Arabic
%   studies.\footnote{See
%   \url{http://www.brill.nl/files/brill.nl/specific/authors_instructions/ARAB.pdf}.}
% \end{description}
% More standards will be included in future releases of
% \package{arabluatex}.
%
% \paragraph{Convention} \DescribeMacro{\SetTranslitConvention} The
% transliteration mode, which is set to |dmg| by default, may be
% changed at any point of the document by the
% \cs{SetTranslitConvention}\marg{mode} command , where \meta{mode}
% may be either |dmg|, |loc| or |arabica|. This command is also
% accepted in the preamble should one wish to set the transliteration
% mode globally, e.g.:---%
% \iffalse
%<*example>
% \fi
\begin{code}
  \usepackage{arabluatex}
  \SetTranslitConvention{loc}
\end{code}
% \iffalse
%</example>
% \fi
%
% \paragraph{Style} \DescribeMacro{\SetTranslitStyle} Any
% transliterated Arabic text is printed in italics by default. This
% also can be changed either globally in the preamble or locally at
% any point of the document by the \cs{SetTranslitStyle}\marg{style}
% command, where \meta{style} may be any font shape selection
% command, e.g. \cs{upshape}, \cs{itshape}, \cs{slshape}, and so forth.
%
% \paragraph{Font} \NEWfeature{v1.4} \DescribeMacro{\SetTranslitFont}
% \cs{SetTranslitFont}\marg{font selection command} allows any
% specific font to be selected for rendering transliterated text with
% the font-selecting commands of the \package{fontspec} or
% \package{luaotfload} package. Of course, this font must have been
% defined properly. To take one example, here is how the \emph{Gentium
% Plus} font can be used for rendering transliterated text:---
% \iffalse
%<*example>
% \fi
\begin{code}
  \newfontfamily\translitfont{Gentium Plus}[Ligatures=TeX]
  \SetTranslitFont{\translitfont}
\end{code}
% \iffalse
%</example>
% \fi
%
% \paragraph{Proper names} \DescribeMacro{\uc} Proper names or book
% titles that must have their first letters uppercased may be passed
% as arguments to the \cs{uc}\marg{word} command. \cs{uc} is a
% clever command, for it will give the definite article
% \arb[trans]{al-} in lower case in all positions. Moreover, if the
% inital letter, apart from the article, cannot be uppercased,
% viz. \arb[trans]{|"'} or \arb[trans]{`}, the letter next to it will be
% uppercased:---
% \begin{quote}
%   |\uc{.hunayn-u}| |bn-u| |\uc{'is.h_aq-a}|
%   \arb[voc]{\uc{.hunayn-u} bn-u \uc{'is.h_aq-a}}
%   \arb[trans]{\uc{.hunayn-u} bn-u \uc{'is.h_aq-a}},
%   |\uc{`u_tm_an-u}| \arb[voc]{\uc{`u_tm_an-u}}
%   \arb[trans]{\uc{`u_tm_an-u}}, |.daraba| |\uc{zayd-u}| |bn-u|
%   |\uc{_h_alidiN}| |\uc{sa`d-a}| |bn-a| |\uc{`awf-i}| |bn-i|
%   |\uc{|\allowbreak|`abd-i}| |\uc{'l-l_ah-i}|
%   \arb[fullvoc]{.daraba \uc{zayd-u} bn-u \uc{_h_alidiN}
%   \uc{sa`d-a} bn-a \uc{`awf-i} bn-i \uc{`abd-i} \uc{'l-l_ah-i}}
%   \arb[trans]{.daraba \uc{zayd-u} bn-u \uc{_h_alidiN} \uc{sa`d-a}
%   bn-a \uc{`awf-i} bn-i \uc{`abd-i} \uc{'l-l_ah-i}}.
% \end{quote}
% However, \cs{uc} must be used cautiously in some very particular
% cases, for the closing brace of its argument may prevent a rule from
% being applied. To take an example, as seen above
% \vpageref{ref:muhammaduni}, the transliteration of
% \arb[fullvoc]{\uc{m}u.hammaduN 'l-nabI} must be
% \arb[trans]{\uc{m}u.hammaduN 'l-nabI}, as nouns having the
% \arb[trans]{tanwIn} take a \arb[trans]{kasraT} in pronunciation
% before \arb[trans]{'alifu 'l-wa.sli}. In that case, encoding
% \arb[fullvoc]{mu.hammaduN} like so: |\uc{mu.hammaduN}| is wrong,
% because the closing brace would prevent \package{arabluatex} from
% detecting the sequence \meta{-uN} immediately followed by
% \meta{'l-}. Fortunately, this can be circumvented in a
% straightforward way by inserting only part of the noun in the
% argument of \cs{uc} vz. up to the first letter that is to be
% uppercased, like so: |\uc{m}u.hammaduN|.
%
% \paragraph{Hyphenation}
% In case transliterated Arabic words break the \TeX\ hyphenation
% algorithm, one may use the |\-| command to insert discretionary
% hyphens. This command will be discarded in all of the Arabic modes
% of \package{arabluatex}, but will be processed by any of the
% transliteration modes:---
% \begin{quote}
%   |\uc{'abU}| |\uc{bakriN}| |\uc{mu\-.ham\-madu}| |bnu|
%   |\uc{za\-ka| |\-riy\-yA'a}| |\uc{'l-rAziyyu}| \arb{\uc{'abU}
%   \uc{bakriN} \uc{mu\-.ham\-mad-u} bnu \uc{za\-ka\-riy\-yA'a}
%   \uc{'l-rAziyyu}} \arb[trans]{\uc{'abU} \uc{bakriN}
%   \uc{mu\-.ham\-mad-u} bn-u \uc{za\-ka\-riy\-yA'-a}
%   \uc{'l-rAziyyu}}.
% \end{quote}
%
% \paragraph{\texorpdfstring{\enquote*{Long} pro\-per
% names}{‘Long’ proper names}}
% \NEWfeature{v1.10} \cs{uc} is also able to process proper names
% consisting of several subsequent words:---
% \begin{quote}
%   |\arb[trans]{\uc{'abU| |zaydiN| |.hunaynu| |bnu| |'is.h_aqa|
%   |'l-`ibAdiyyu}}| \arb[trans]{\uc{'abU zaydiN .hunaynu bnu
%   'is.h_aqa 'l-`ibAdiyyu}}.
% \end{quote}
%
% \paragraph{Proper names outside Arabic environments}
% \changes{v1.10}{2018/01/03}{\cs{uc} supersedes \cs{cap}}
% \DescribeMacro{\prname}\NEWfeature{v1.10} Transliterated proper
% names inserted in paragraphs of English text should be printed in
% the same typeface as the surrounding text. \cs{prname}\marg{Arabic
% proper name} is provided to that effect:\footnote{Just as \cs{uc},
% \cs{prname} is also able to process proper names consisting of
% several subsequent words.}---
%\iffalse
%<*example>
% \fi
\begin{example}
  From \textcite[i. 23 C]{Wright}:--- If the name following
  \arb[fullvoc]{ibnuN} be that of the mother or the grandfather, the

  \enquote{Jesus the son of Mary}; \arb[fullvoc]{`ammAru ibnu

% \iffalse
%</example>
% \fi
%
% The following example shows how \cs{prname} can be used in

    \prname{al-rAziyy} & > %
  \end{nameauth}

  On first occurrence, proper names are printed as \Hunayn, \Razi.
  Then as \Hunayn, \Razi.
\end{example}
% \iffalse
%</example>
% \fi
% 
% \begin{quoting}\label{ref:prname-star}
%   \textsc{Rem.} \DescribeMacro{\prname*} \package{arabluatex} also
%   provides \cs{prname*} which only renders in upright roman style
%   already transliterated proper names without applying any further

%   names exported in Unicode to an external selected
%   file.\footnote{See below \vref{sec:arabtex2utf} for more details.}
% \end{quoting}
% 
% \subsection{Additional note on \texttt{dmg} convention}
% \label{sec:additional-note-dmg}
% \NEWfeature{v1.3} According to \textcite[6]{dmg}, Arabic
% \arb[trans]{'i`rAb} may be rendered into |dmg| in three different
% ways:
% \begin{enumerate}
% \item \label{ref:dmg-full-rend}In full:
%   \NoArbUp\arb[trans]{\uc{`amruNU}}\ArbUpDflt\,;
% \item \label{ref:dmg-up-rend}As superscript text:
%   \arb[trans]{\uc{`amruNU}}\,;
% \item \label{ref:irab-discarded}Discarded: \arb[trans]{\uc{`amr}}.
% \end{enumerate}
% \DescribeMacro{\arbup} By default, \package{arabluatex} applies rule
% \ref{ref:dmg-up-rend}. Once delimited by a set of Lua functions,
% \arb[trans]{'i`rAb} is passed as an argument on to a \cs{arbup}
% command which is set to \cs{textsuperscript}.
%
% \DescribeMacro{\NoArbUp} \DescribeMacro{\ArbUpDflt} \cs{NoArbUp} may
% be used either in the preamble or at any point of the document in
% case one wishes to apply rule \ref{ref:dmg-full-rend}. The default
% rule \ref{ref:dmg-up-rend} can be set back with \cs{ArbUpDflt} at
% any point of the document.
%
% \DescribeMacro{\SetArbUp} Finally, \cs{SetArbUp}\marg{formatting
% directives} can be used to customize the way \arb[trans]{'i`rAb} is
% displayed. To take one example, here is how Arabic
% \arb[trans]{'i`rAb} may be rendered as subscript text:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \SetArbUp{\textsubscript{#1}}
  Arabic |dmg| transliteration for \arb{ra'aytu ^gAmi`aN
    muhaddamaTaN mi'_danatu-hu}: \arb[trans]{ra'aytu
    ^gAmi`aN muhaddamaTaN mi'_danatu-hu.}
\end{example}
% \iffalse
%</example>
% \fi
%
% As shown in the above example, |#1| is the token that is replaced
% with the actual \arb[trans]{tanwIn} in the formatting directives of
% the \cs{SetArbUp} command.
%
% \paragraph{\texorpdfstring{\arb[trans]{'i`rAb} boundaries}{ʾiʿrāb
% boundaries}}
% Every declinable noun (\arb[trans]{mu`rab}) may be declined either
% with or without \arb[trans]{tanwIn}, viz. \arb[trans]{mun.sarifuN}
% or \arb[trans]{.gayr-u mun.sarifiN}. The former is automatically
% parsed by \package{arabluatex}, whereas the latter has to be
% delimited with an hyphen, like so:---
% \begin{quote}
%   \arb[trans]{\textbf{mun.sarif}}: |mu`allimuN|
%   \arb[voc]{mu`allimuN} \arb[trans]{mu`allimuN}, |kA'inuN|
%   \arb[voc]{kA'inuN} \arb[trans]{kA'inuN}, |kA'inAtuN|
%   \arb[voc]{kA'inAtuN} \arb[trans]{kA'inAtuN}, |\uc{`amraNU}|
%   \arb[voc]{\uc{`amraNU}} \arb[trans]{\uc{`amraNU}}, |fataN_A|
%   \arb[voc]{fataN_A} \arb[trans]{fataN_A}, |qA.diNI| \arb{qA.diNI}
%   \arb[trans]{qA.diNI}.
%
%   \arb[trans]{\textbf{.gayr mun.sarif}}: |al-mu`allim-u|
%   \arb[voc]{al-mu`allim-u} \arb[trans]{al-mu`allim-u}, |kitAb-Ani|
%   \arb[voc]{kitAb-Ani} \arb[trans]{kitAb-Ani}, |ra^sa'-Ani|
%   \arb[voc]{ra^sa'-Ani} \arb[trans]{ra^sa'-Ani}, |sAriq-Una|
%   \arb[voc]{sAriq-Una} \arb[trans]{sAriq-Una}, |qA.d-Una|
%   \arb[voc]{qA.d-Una} \arb[trans]{qA.d-Una}, |al-.zulm-Atu|
%   \arb[voc]{al-.zulm-Atu} \arb[trans]{al-.zulm-Atu}.
% \end{quote}
%
% \begin{quoting}
%   \textsc{Rem.}~\emph{a.} As the \arb[trans]{tanwIn} is passed over
%   in pronunciation when it is followed by the letters
%   \arb[novoc]{r}, \arb[novoc]{l}, \arb[novoc]{m}, \arb[novoc]{w},
%   \arb[novoc]{y} (see \vref{ref:assimilation}), it may be desirable
%   to further distinguish it by putting it above the line, but not to
%   do the same for \arb[trans]{.gayr mun.sarif} terminations. This
%   can be achieved by simply omitting the hyphen before any
%   \arb[trans]{.gayr mun.sarif} termination:---\\
%   |kAna| |.ganiyyaN| |l_akinna-hu| |labisa| |^gubbaTaN| |mumazzaqaN|
%   |'aydu-hA| \arb[voc]{kAna .ganiyyaN l_akinna-hu labisa ^gubbaTaN
%   mumazzaqaN 'aydu-hA} \arb[trans]{kAna .ganiyyaN l_akinna-hu labisa
%   ^gubbaTaN mumazzaqaN 'aydu-hA}.
%
%   \textsc{Rem.}~\emph{b.} Although the hyphen before the
%   \arb[trans]{tanwIn} is optional as \package{arabluatex} always
%   parses nouns with such termination, it may also be used to mark
%   better the inflectional endings:---\\
%   |mana`a| |'l-nAs-a| |kAffaT-aN| |min| |mu_hA.tabati-hi|
%   |'a.had-uN| |bi-sayyidi-nA| \arb[voc]{mana`a 'l-nAs-a kAffaT-aN
%   min mu_hA.tabati-hi 'a.had-uN bi-sayyidi-nA} \arb[trans]{mana`a
%   'l-nAs-a kAffaT-aN min mu_hA.tabati-hi 'a.had-uN bi-sayyidi-nA}.
% \end{quoting}
% 
% \paragraph{\texorpdfstring{Discar\-ding the
% \arb[trans]{'i`rAb}}{Discarding the ʾiʿrāb}}
% \label{ref:ta-marbutah-pipe}
% As said above (\vref{ref:irab-discarded}), the \arb[trans]{'i`rAb}
% may be discarded in some cases, as in transliterated proper names or
% book titles. \package{arabluatex} is able to render words ending
% with \arb[trans]{tA' marbU.taT} in different ways, depending on
% their function:---
% \begin{enumerate}
% \item Nouns followed by an adjective in apposition: |madInaT|
%   |kabIraT| \arb[trans]{madInaT kabIraT}, |al-madInaT| |al-kabIraT|
%   \arb[trans]{al-madInaT al-kabIraT}.
% \item Nouns followed by another noun in the genitive (contruct
%   state): |.hikmaT| |al-l_ah| \arb[trans]{.hikmaT| \uc{al-l_ah}},
%   |fi.d.daT| |al-darAhim| \arb[trans]{fi.d.daT al-darAhim}.
% \end{enumerate}
% \begin{quoting}
%   \textsc{Rem.} It may so happen, as in the absence of the article
%   before the annexed word, that \package{arabluatex} be unable to
%   determine which of the above two cases the word ending with
%   \arb[trans]{tA' marbU.taT} falls into. The \enquote*{pipe}
%   character (see \vref{sec:pipe}) may be appended to that word to
%   indicate that what follows is in the construct state:
%   |\uc{r}isAlaT| |fI| |tartIb| \verb+qirA'aT|+ |kutub|
%   |\uc{^g}AlInUs| \arb[trans]{\uc{r}isAlaT fI tartIb qirA'aT|
%   kutub \uc{^g}AlInUs}.
% \end{quoting}
% 
%
% \paragraph{Uncertain short vowels}
% In some printed books, it may happen that more than one short vowel
% be placed on a consonant in cases where the vocalization is
% uncertain or ambiguous, like so: \arb[voc]{fa`uaila}. In
% transliteration, the uncertain vowels go between slashes and are
% separated by commas: |fa`uaila| \arb[voc]{fa`uaila}
% \arb[trans]{fa`uaila}.

% \section{Buckwalter input scheme}
% \label{sec:buckwalter-scheme}
% \NEWfeature{v1.4} Even though \package{arabluatex} is primarily
% designed to process the Arab\TeX\ notation, it can also process the
% Buckwalter input scheme to a large extent.\footnote{See
% \url{http://www.qamus.org/transliteration.htm}} The Buckwalter
% scheme is actually processed in two steps, as it is first converted
% into Arab\TeX. Then, once this is accomplished, the Arab\TeX\ scheme
% is processed through the above described functions. In this way, the
% Buckwalter input scheme can make the most of the
% \package{arabluatex} special features that are presented in
% \vref{sec:options}.
%
% \DescribeMacro{\SetInputScheme} The input scheme, which is set to
% |arabtex| by default, may be changed at any point of the document by
% the \cs{SetInputScheme}\marg{scheme} command, where \meta{scheme}
% may be either |arabtex| or |buckwalter|. This command is also
% accepted in the preamble should one wish to set the input scheme
% globally, like so:---
% \iffalse
%<*example>
% \fi
\begin{code}
  \usepackage{arabluatex}
  \SetInputScheme{buckwalter}
\end{code}
% \iffalse
%</example>
% \fi
%
% \paragraph{\texorpdfstring{\enquote*{base}, \enquote*{\texttt{xml}}
% and \enquote*{safe} schemes}{‘base’, ‘xml’ and ‘safe’ schemes}}
% \package{arabluatex} can use any of the so-called Buckwalter
% \enquote*{base}, \enquote*{\texttt{xml}} or \enquote*{safe} schemes
% as they are described in \textcite[25--26]{Habash}.\footnote{I am
% grateful to Graeme Andrews who suggested that the \enquote*{safe}
% scheme be included in \package{arabluatex}.} However, the following
% limitation apply to the \enquote*{base} and \enquote*{\texttt{xml}}
% schemes: the braces |{| and |}|, which are used to encode
% \arb[novoc]{"a} and \arb[novoc]{y"'}, must be replaced with square
% brackets viz. |[| and |]| respectively.
%
% It is therefore recommended to use the Buckwalter \enquote*{safe}
% scheme.
%
% \Cref{tab:buckwalter-scheme} gives the Buckwalter equivalents that
% are currently used by \package{arabluatex}. The additional
% characters that are defined in \vref{tab:additional-arabic-codings}
% are also available.

% \paragraph{Transliteration}
% The Buckwalter notation can also be transliterated into any accepted
% romanization standard of Arabic. See above
% \vref{sec:transliteration} for more information. However, it should
% be pointed out again that only accurate coding produces accurate
% transliteration. It is therefore at the very least highly advisable
% to use the hyphen for tying the definite article and the inseparable
% particles (viz. prepositions, adverbs and conjunctions) to words,
% like so:--- \SetInputScheme{buckwalter}
% \begin{quote}
%   |Al-EaAlamu| \arb{Al-EaAlam-u} \arb[trans]{Al-EaAlam-u},
%   |Al-camsu| \arb{Al-cams-u} \arb[trans]{Al-cams-u},
%   |bi-SinaAEapi| |Al-T~ib~i|, \arb{bi-SinaAEap-i Al-T~ib~-i}
%   \arb[trans]{bi-SinaAEap-i Al-T~ib~-i}.
%
%   |wa-Al-l~ehi| \arb{wa-Al-l~eh-i} \arb[trans]{wa-Al-l~eh-i},
%   |Al-Hamdu| |li-l~ehi| \arb{Al-Hamd-u li-l~eh-i}
%   \arb[trans]{Al-Hamd-u li-l~eh-i}.
% \end{quote}
% \SetInputScheme{arabtex}
%
% Similary, it is not advisable to use \verb+|+ and |[|
% (\enquote*{base} and \enquote*{\texttt{xml}} schemes) or |M| and |L|
% (\enquote*{safe} scheme) to encode the \arb[trans]{'alif-u
% 'l-mamdUdaT-i} and the \arb[trans]{'alif-u 'l-wa.sl-i} for such
% signs are supposed to be generated by \package{arabluatex} internal
% functions.  Besides, as they do not \emph{per se} convey any
% morphological information on what they are derived from, they cannot
% be transliterated accurately. To take one example, %
% \SetInputScheme{buckwalter}%
% |<ilY Al-LntiqaADi| gives \arb{>ilY Al-LntiqaADi} as expected, but
% only |<ilY Al-intiqADi| can be transliterated as \arb[trans]{<ilY
% Al-intiqaADi} with the correct vowel \meta{i} in place of the %
% \SetInputScheme{arabtex}%
% \arb[trans]{'alif-u 'l-wa.sl-i}.
%
% \section{Unicode Arabic input}
% \label{sec:unicode-input}
% \NEWfeature{v1.5} As said above in \vref{sec:buckwalter-scheme}
% about the Buckwalter input scheme, even though \package{arabluatex}
% is primarily designed to process the Arab\TeX\ notation, it also
% accepts Unicode Arabic input. It should be noted that
% \package{arabluatex} does in no way interfere with Unicode Arabic
% input: none of the |voc|, |fullvoc|, |novoc| or |trans| options will
% have any effect on plain Unicode Arabic for the time being.
%
% That said, there are two ways of inserting Unicode
% Arabic:
% \begin{enumerate}
% \item \DescribeMacro{\txarb} The \cs{txarb}\marg{Unicode Arabic}
%   command for inserting Unicode Arabic text in paragraphs;
% \item The \DescribeEnv{txarab} |txarab| environment for inserting
%   running paragraphs of Arabic text, like so:---\\%
% \iffalse
%<*example>
% \fi
\begin{code}
  \begin{txarab}
    <Unicode Arabic text>
  \end{txarab}
\end{code}
% \iffalse
%</example>
% \fi
% \end{enumerate}
%
% \needspace{4\baselineskip}
% \section{\LaTeX\ Commands in Arabic environments}
% \label{sec:commands-in-arb}
% \paragraph{General principle} \label{ref:cmd-inside-arabic}\LaTeX\
% commands are accepted in Arabic environments. The general principle
% which applies is that any single-argument command with up to
% \emph{two optional arguments}---that is:
% \cs{command}\oarg{opt1}\oarg{opt2}\marg{arg}---such as
% \cs{emph}\marg{text}, \cs{textbf}\marg{text} and the like, is
% assumed to have Arabic text in its mandatory argument:---
% \begin{quote}
%   |\abjad{45}| |kitAbu-hu| |\emph{fI| |'l-\uc{`AdAt-i}}|
%   \arb[voc]{\abjad{45} kitAbu-hu \emph{fI 'l-\uc{`AdAt-i}}}
%   \arb[trans]{\abjad{45} kitAbu-hu \emph{fI
%   'l-\uc{`AdAt-i}}}.\footnote{This is odd in Arabic script, but
%   using such features as \cs{emph} or \cs{textbf} is a matter of
%   personal taste.}
%   \NewDocumentCommand{\rlframebox}{o o m}{
%    \IfNoValueTF{#2}{\IfNoValueTF{#1}{
%    \framebox{\setRL#3}}{\framebox[#1]{\setRL#3}}
% }{\framebox[#1][#2]{\setRL#3}}}
%
%   |\arb{\abjad{45} \rlframebox[1in][s]{kitAbu-hu fI 'l-`AdAti}}|\\
%   \arb{\abjad{45} \rlframebox[1in][s]{kitAbu-hu fI
%   'l-`AdAti}}\,\footnote{\cs{rlframefox} has been adapted from
%   \cs{framebox} for insertions of right-to-left text.}
% \end{quote}
% 
% The same applies to footnotes:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \renewcommand{\footnoterule}%
  {\hfill\noindent\rule[1mm]{.4\textwidth}{.15mm}}
  \begin{arab}
    'inna 'abI kAna mina 'l-muqAtilaT-i\footnote{al-muqAtilaT-i:
      al-muqAtil-Ina.}, wa-kAnat 'ummI min `u.zamA'-i buyUt-i
    'l-zamAzimaT-i\footnote{al-zamAzimaT-u: .tA'ifaT-u mina
      'l-furs-i.}.
  \end{arab}
\end{example}
% \iffalse
%</example>
% \fi
%
% Some commands, however, do not expect running text in their
% arguments, or one may wish to insert English text e.g. in footnotes
% or in marginal notes. \package{arabluatex} provides a set of
% commands to handle such cases.
%
% \DescribeMacro{\LR} \cs{LR}\marg{arg} is designed to typeset its
% argument from left to right. It may be used in an Arabic
% environment, either \cs{arb}\marg{Arabic text} or \cs{begin}|{arab}|
% \meta{Arabic text} \cs{end}|{arab}|, for short insertions of
% left-to-right text, or to insert any \LaTeX\ command that would
% otherwise be rejected by \package{arabluatex}, such as commands the
% argument of which is expected to be a dimension or a unit of
% measurement.
%
% \DescribeMacro{\RL} \cs{RL}\marg{arg} does the same as
% \cs{LR}\marg{arg}, but typesets its argument from right to left. Even
% in an Arabic environment, this command may be useful.
% 
% \DescribeMacro{\LRfootnote} \DescribeMacro{\RLfootnote}
% \cs{LRfootnote}\marg{text} and \cs{RLfootnote}\marg{text} typeset
% left-to-right and right-to-left footnotes respectively in Arabic
% environments. Unlike \cs{footnote}\marg{text}, the arguments of both
% \cs{LRfootnote} and \cs{RLfootnote} are not expected to be Arabic
% text. For example, \cs{LRfootnote} can be used to insert English
% footnotes in running Arabic text:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \begin{arab}[fullvoc]
    \uc{z}ayd-uN\arbnull{ibnu}\LRfootnote{%
      \enquote{\arb[trans]{\uc{z}ayd} is the son of
        \arb[trans]{\uc{`a}mr}}: the second noun is not in
      apposition to the first, but forms part of the
      predicate\ldots} \arbnull{zayduN}ibn-u \uc{`a}mr-iNU
  \end{arab}
\end{example}
% \iffalse
%</example>
% \fi
%
% When footnotes are typeset from right to left, it may happen that
% the numbers of the footnotes that are at the bottom of the page be
% typeset in the wrong direction. For example, instead of an expected
% number 18, one may get 81. \package{arabluatex} is not responsible
% for that, but should it happen, it may be necessary to redefine in
% the preamble the \LaTeX\ macro \cs{thefootnote} like so:---\\
% \tcboxverb{\renewcommand*{\thefootnote}{\textsuperscript{\LR{\arabic{footnote}}}}}
% \DescribeMacro{\FixArbFtnmk} Another solution is to put in the
% preamble, below the line that loads \package{arabluatex}, the
% \cs{FixArbFtnmk} command. However, for more control over the layout
% of footnotes marks, it is advisable to use the \package{scrextend}
% package.\footnote{See \url{http://ctan.org/pkg/koma-script}; read
% the documentation of \package{KOMA-script} for details about the
% \cs{deffootnotemark} and \cs{deffootnote} commands.}
%
% \DescribeMacro{\LRmarginpar} The
% \cs{LRmarginpar}\oarg{left}\marg{right} command does for marginal
% notes the same as \cs{LRfootnote} does for footnotes. Of course, it
% is supposed to be used in Arabic environments. Note that
% \cs{marginpar} also works in Arabic environments, but it acts as any
% other single-argument command inserted in Arabic environments. The
% general principle laid \vpageref{ref:cmd-inside-arabic} applies.
%
% \label{ref:setrl-setlr}
% \DescribeMacro{\setRL} \DescribeMacro{\setLR} \cs{setRL} and
% \cs{setLR} can be used to change the direction of paragraphs, either
% form left to right or from right to left. As an example, an
% easy way to typeset a right-to-left sectional title follows:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \setRL
  \section*{\arb{barzawayhi li-buzurjumihra bn-i 'l-buxtikAni}}
  \setLR
  \begin{arab}
    qAla barzawayhi bn-u 'azhar-a, ra's-u 'a.tibbA'-i fAris-a...
  \end{arab}
\end{example}
% \iffalse
%</example>
% \fi
%
% \subsection{New commands}
% \label{sec:declare-new-commands}
% \NEWfeature{v1.9}%
% In some particular cases, it may be useful to define new commands to
% be inserted in Arabic environments. From the general principle laid
% \vpageref{ref:cmd-inside-arabic}, it follows that any command that
% is found inside an Arabic environment is assumed to have Arabic text
% in its argument which \package{arabluatex} will process as such
% before passing it on to the command itself for any further
% processing. As a result of this feature, such a command as:\\
% \tcboxverb{\newcommand{\fvarabic}[1]{\arb[fullvoc]{#1}}}\\
% will work as expected, but will always output non-vocalized Arabic
% if it is inserted in a |novoc| Arabic environment because its
% argument will have been processed by the |novoc| rules before the
% command |\fvarabic| itself can see it.
%
% \DescribeMacro{\MkArbBreak} The \cs{MkArbBreak}\marg{csv list of
% commands} command can be used in the preamble to give any
% command---either new or already existing---the precedence over
% \package{arabluatex} inside Arabic environments. It takes as
% argument a comma-separated list of commands each of which must be
% stripped of its leading character
% |\|, like so:---\\
% \tcboxverb{\MkArbBreak{onecmd, anothercmd, yetanothercmd, ...}}
% 
% For example, here follows a way to define a new command |\fvred| to
% distinguish words with a different color and always print them in
% fully vocalized Arabic:--- %
% \iffalse
%<*example>
% \fi
\begin{example}
  \MkArbBreak{fvred}
  \newcommand{\fvred}[1]{\arbcolor[red]{\arb[fullvoc]{#1}}}
  \begin{arab}[voc]
    _tumma "intalaqa _dU 'l-qarn-ayni 'il_A 'ummaT-iN 'u_hr_A fI
    \fvred{((ma.tli`-i 'l-^sams-i))} wa-lA binA'-a la-hum
    yu'amminu-hum mina 'l-^sams-i.
  \end{arab}
\end{example}
% \iffalse
%</example>
% \fi
%
% It must be noted that the arguments, either optional or mandatory,
% of commands declared with \cs{MkArbBreak} are not to be processed by
% \package{arabluatex}. Therefore, as in the previous example, any of
% their argument to be rendered in Arabic must be inserted again in
% \cs{arb}. \NEWfeature{v1.12}These commands themselves may have up to
% two optional and/or mandatory arguments followed by one optional
% argument, like so:---
% \begin{enumerate}
% \item \cs{command} (no argument, lowermost combination)
% \item \cs{command}\oarg{opt1} (one optional argument)
% \item \cs{command}\marg{arg1} (one mandatory argument)
% \item \cs{command}\oarg{opt1}\marg{arg1} (one optional and one
%   mandatory argument)
% \item{} [\ldots]
% \item \cs{command}\oarg{opt1}\oarg{opt2}\marg{arg1}\marg{arg2}
% \item
%   \cs{command}\oarg{opt1}\oarg{opt2}\marg{arg1}\marg{arg2}\oarg{opt3}
%   (uppermost combination)
% \end{enumerate}
%
% \DescribeMacro{\MkArbBreak*}\NEWfeature{v1.12} As said above,
% \cs{MkArbBreak} prevents \package{arabluatex} from processing the
% arguments of \enquote*{declared} commands as Arabic text. This
% technique proves sufficient in most cases. However, a
% \enquote*{starred} version of this
% command---\cs{MkArbBreak*}\marg{csv list of commands}---is also
% provided. It goes a step further, as it directs \package{arabluatex}
% to \emph{close} the current Arabic environment before any of the
% \enquote*{declared} commands, then \emph{resume} it just after.
% 
% \iffalse
%<*example>
% \fi
\begin{tcblisting}{text only}
  It must be noted that \cs{MkArbBreak*} must be used with the utmost
  care and \emph{should never be used} if \cs{MkArbBreak} gives
  satisfaction. At any rate, the latter must always be tested before
  the former.

% \subsubsection{Lists}
% \label{sec:lists}
% Lists environments are also accepted inside the |arab|
% environment. One may either use any of the three standard list
% environments, viz. |itemize|, |enumerate| and |description| or use
% packages that provide additional refinements such as
% \package{paralist} or \package{enumitem}.
%
% To take a first example, should one wish to typeset a list of
% manuscripts, the |description| environment can be used like so:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \setRL\paragraph{\arb[novoc]{rumUzi 'l-kitAbi}}\setLR
  \begin{arab}[novoc]
    \begin{description}

% \paragraph{Caveat}
% The various French definition files of the \package{babel} package
% viz. |acadian|, |canadien|, |francais|, |frenchb| or |french| all
% redefine the list environments, which breaks the standard definition
% file that is used by \package{arabluatex}. Therefore,
% \package{babel-french} must be loaded with the |StandardLists=true|
% option, like so:---%
% \iffalse
%<*example>
% \fi
\begin{code}
  \usepackage[french]{babel}
  \frenchsetup{StandardLists=true}
\end{code}
% \iffalse
%</example>
% \fi%
% This option will prevent \package{babel-french} from interfering
% with the layout of the document. Then the \package{paralist} or
% \package{enumitem} packages can be used to make the lists
% \enquote*{compact} as \package{babel-french} do.
%
% \subsection{\package{csquotes}}
% \label{sec:csquotes}
% The recommended way of inserting quotation marks in running Arabic
% text is to use \package{csquotes}. With the help of the

  {\textquotedblright}{\textquotedblleft}

\end{code}
% \iffalse
%</example>
% \fi
% Then, use this newly defined style with \cs{setquotestyle}, like so:---
% \iffalse
%<*example>
% \fi
\begin{example}
  \setquotestyle{arabic}
  \begin{arab}
    fa-qAla la-hu ju.hA: \enquote{.garIb-uN 'amru-ka yA .sadIqI

  \setquotestyle{english}
\end{example}
% \iffalse
%</example>
% \fi
% \begin{quoting}

% \subsection{\package{quran}}
% \label{sec:pkg-quran}
% \changes{v1.5}{2016/11/14}{Compatibility with the \textsf{quran}
% package} \package{arabluatex} is compatible with the \package{quran}
% package so that both can be used in conjunction with one another for
% typesetting the \arb[trans]{\uc{qur'An}}. As \package{quran} draws
% the text of the \arb[trans]{\uc{qur'An}} from a Unicode encoded
% database, its commands have to be passed as arguments to the
% \cs{txarb} command for short insertions in left-to-right paragraphs,
% or inserted inside the \index{txarab=txarab (environment)}|txarab|
% environment for typesetting running paragraphs of
% \arb[trans]{\uc{qur'An}}\emph{ic} text (see above
% \vref{sec:unicode-input} for more details). Please note that
% \package{arabluatex} takes care of formatting the Arabic: therefore,

% \section{Exporting Unicode Arabic to an external file}
% \label{sec:arabtex2utf}
% \NEWfeature{v.1.13}\package{arabluatex} is able to produce a
% duplicate of the original |.tex| source file in which all |arabtex|
% or |buckwalter| strings will have been replaced with Unicode
% equivalents, either in Arabic script or in any accepted standard of
% transliteration. Exporting \textsc{ascii} strings to Unicode while
% preserving the exact selected global or local options is a fairly
% complex operation which may require {\LuaLaTeX} to be run several
% times as will be explained below.
%
% \subsection{Commands and environments}
% \paragraph{\texttt{export} global option}
% \DescribeOption{export} First, \package{arabluatex} must be loaded
% with the |export| global option enabled,\footnote{See above
% \vpageref{ref:export-global-opt} for more information.} like
% so:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  % preamble
  \usepackage[export]{arabluatex}
  % or:
  \usepackage[export=true]{arabluatex}
\end{code}
% \iffalse
%</example>
% \fi
% 
% Once that is done, compiling the current file will produce a new
% empty external |.tex| file with the same preamble as the original
% file.
%
% \DescribeMacro{\SetArbOutSuffix} By default, |_out| is appended as a
% suffix to the external file name. Any other suffix may be set with
% the command \cs{SetArbOutSuffix}\marg{suffix}.
%
% \paragraph{Exporting running paragraphs}
% \DescribeEnv{arabexport} Then, the |arabexport| environment is
% provided to actually exporting running paragraphs with or without
% Arabic environments to the external selected file, like so:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  \begin{arabexport}
    <Running paragraphs of either Arabic or non-Arabic text>
  \end{arabexport}
\end{code}
% \iffalse
%</example>
% \fi
% 
% \package{arabluatex} converts to Unicode and writes to the external
% file what is found inside Arabic environments. As to non-Arabic
% text, it is appended untouched to this file, which is formatted as
% follows:---
% \begin{enumerate}
% \item Unicode Arabic text, either in Arabic script or in
%   transliteration, is inserted as argument of
%   \cs{txarb}\footnote{See above \vref{sec:unicode-input}.} or
%   \cs{txtrans}\footnote{\cs{txtrans} is used internally by several
%   Lua functions to format transliterated Arabic. Therefore, it is
%   not documented.} accordingly.
% \item \DescribeMacro{\arbpardir}Additionally, Arabic paragraphs may
%   receive \cs{arbpardir}, which \package{arabluatex} uses to
%   determine the direction of Arabic paragraphs to be set by default,
%   or either \cs{setRL} or \cs{setLR} depending on what may have been
%   set locally.\footnote{See above \vpageref{ref:setrl-setlr}.}
% \item \DescribeMacro{\prname*}Proper names are inserted as arguments
% of \cs{prname*}.\footnote{See above \vpageref{ref:prname-star}.}
% \end{enumerate}
% 
% \paragraph{Appending words or commands to the external file only}
% \DescribeMacro{\ArbOutFile}\DescribeMacro{\ArbOutFile*}
% \cs{ArbOutFile}\oarg{newline}\allowbreak\marg{argument} silently
% exports its argument to the external file. It may take the string
% |newline| as an optional argument, in which case a carriage return
% is appended to the contents of the
% argument. \cs{ArbOutFile*}\oarg{newline}\marg{argument} does the
% same as \cs{ArbOutFile}, but also inserts its argument into the
% current |.tex| source file.
%
% \paragraph{Exporting Arabic poetry}
% Lines of Arabic poetry are exported as described above
% \vpageref{ref:poetry-export} when the |export| option that is
% specific to the |arabverse| environment is set to |true|. As a
% result of this particular feature, |arabverse| environments must be
% left outside |\begin{arabexport}| \ldots\ |\end{arabexport}|.
%
% Please note that inside |arabverse| environments \cs{bayt} is
% replaced with \cs{bayt*}.\footnote{See above \vref{ref:bayt-star} for
% more information.}
%
% \subsection{Nested Arabic environments}
% The exporting mechanism described above converts only the outermost
% level of nested Arabic environments. This may be sufficient in some
% cases, but if nested Arabic environments be found in the original
% |.tex| source file, then the Unicode converted file must be opened
% and compiled in turn, and so on until the innermost Arabic
% environment be converted and exported. In such cases,
% \package{arabluatex} issues a warning, so that authors do not have
% to check the entire file that just has been exported:--- %
% \iffalse
%<*example>
% \fi
\begin{code}
  Package arabluatex Warning: There are still 'arabtex' strings
  to be converted. Please open <jobname><suffix>.tex and compile
  it one more time.
\end{code}
% \iffalse
%</example>
% \fi
% Where \meta{jobname} is the name of the original |.tex| source file,
% and \meta{suffix} the suffix appended to the file that is to be
% opened and compiled again.
%
% \subsection{Further processing of Unicode converted files}
% \label{sec:further-processing-utf-files}
% Unicode files can be further processed by document converters such
% as John McFarlane's |pandoc|\footnote{See
% \url{http://pandoc.org/}}. To take here one simple example, here is
% how |file_out.tex| can be converted from {\LuaLaTeX} into Open
% Document format (|.odt|):---%
% \iffalse
%<*example>
% \fi
\begin{code}
  pandoc file_out.tex -s -o file_out.odt
\end{code}
% \iffalse
%</example>
% \fi
% 
% However, specific commands such as \cs{txarb}, \cs{txtrans} or
% \cs{prname*}, which are not known to |pandoc|, must be redefined
% explicitly in the preamble to prevent the converter from gobbling
% their arguments, like so:---%
% \iffalse
%<*example>
% \fi
\begin{code}
  % preamble:
  \usepackage{arabluatex} % note that 'export' has been removed
  \renewcommand{\txarb}[1]{#1}
  \renewcommand{\txtrans}[1]{\emph{#1}}
  \renewcommand{\arbup}[1]{\textsuperscript{#1}}
  % now that \prname{} has been replaced with \prname*{} it should
  % be safe to say:
  \renewcommand{\prname}[2]{#2}
  % &c
\end{code}
% \iffalse
%</example>
% \fi
%
% \section{Future work}
% \label{sec:future-work}
% A short, uncommented, list of what is planned in the versions of
% \package{arabluatex} to come follows:
% \begin{enumerate}
% \item Short-term:
%   \begin{enumerate}
%   \item \texttt{TEI xml} support: \package{arabluatex} will
%     interoperate with \texttt{TEI xml} through new global and local
%     options that will output Arabic in a \texttt{TEI xml} compliant
%     file in addition to the usual PDF output: see
%     \vpageref{ref:tei-to-come}.
%   \end{enumerate}
% \item Medium-term:
%   \begin{enumerate}
%   \item More languages: the list of supported languages will
%     eventually be the same as \package{arabtex}: see
%     \vref{fn:arabtex-languages}.
%   \item Formulate propositions for extending the Arab\TeX\ notation
%     and the transliteration tables. Include them in
%     \package{arabluatex}. See \vref{sec:additional-characters}.
