% \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]{\cap{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}}
% As usual put in your preamble:\\
% \arabluaverb{\usepackage{arabluatex}}\\
% The only requirement of \package{arabluatex} is \LuaLaTeX; it will
% complain if you try to compile your document with another
% engine. That aside, \package{arabluatex} does not load packages such
% as \package{polyglossia} or \package{luabidi}. It can work with
% \package{polyglossia} though, but does not require it.
%
% \paragraph{Font setup}
% If you wish to use your own Arabic font, you can define it before
% loading \package{arabluatex}. Assuming that \package{fontspec} is
% loaded, put this in your 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 you wish to use.
%
% 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:---\\
% \arabluaverb{\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 {\newfontfamily\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[5]{pkg:amiri}.}\\
%   \arabluaverb{\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 four mutually exclusive
% global options, each of which may be overriden at any point of the
% document (see below \vref{sec:local-options}):
% 
% \DescribeOption{voc}\hfill\arabluaverb{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, two standards are supported (see below
% \vref{sec:transliteration} for more details):
% \begin{compactdesc}
% \item[dmg] \emph{Deutsche Morgenländische Gesellschaft}, which is
%   selected by default;
% \item[loc] \emph{Library of Congress}.
% \end{compactdesc}
% More standards will be included in future releases of
% \package{arabluatex}.
% 
% \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{compactitem}
% \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 Assimilation rules laid on \vref{ref:assimilation} are
%   applied.
% \item In |fullvoc| mode, the \arb[trans]{sukUn} is expressed.
% \end{compactitem}
% 
% \DescribeMacro{\SetArbEasy} \DescribeMacro{\SetArbDflt} Such
% refinements may be discarded by the command \cs{SetArbEasy}, either
% globally in the preamble or locally at any point of the
% document. Default \enquote*{classic} rules may be set back at any
% point of the document with the command \cs{SetArbDflt}. Examples
% follow:---
% \begin{compactenum}[(a)]
% \item \cs{SetArbDflt}:
%   \begin{compactenum}[i.]
%   \item |voc| \arb[voc]{wa-mAta istisqA'aN qabla 'an yutimma
%     kitAba-hu fI nujUm-i 'l-samA'-i}
%   \item |fullvoc| \arb[fullvoc]{wa-mAta istisqA'aN qabla 'an yutimma
%     kitAba-hu fI nujUm-i 'l-samA'-i}
%   \item |trans| \arb[trans]{wa-mAta istisqA'aN qabla 'an yutimma
%     kitAba-hu fI nujUm-i 'l-samA'-i}
%   \end{compactenum}
% \item \cs{SetArbEasy}:
%   \begin{compactenum}[i.]\SetArbEasy

%\subsection{Typing Arabic}
% \DescribeMacro{\arb} Once \package{arabluatex} is loaded, a command
% \cs{arb}\marg{Arabic text} is available for inserting Arabic text in
% paragraphs, like so:---
% \iffalse
%<*example>
% \fi
\begin{arabluacode}
From \textcite[i. 1 A]{Wright}:--- Arabic, like Hebrew and
Syriac, is written and read from right to left. The letters
of the alphabet (\arb{.hurUf-u 'l-hijA'-i}, \arb{.hurUf-u
'l-tahajjI}, \arb{al-.hurUf-u 'l-hijA'iyyaT-u}, or
\arb{.hurUf-u 'l-mu`jam-i}) are twenty-eight in number and
are all consonants, though three of them are also used as
vowels (see §~3).
\end{arabluacode}
% \iffalse

% \subsubsection{Local options}
% \label{sec:local-options}
% As seen above in \vref{sec:options}, \package{arabluatex} may be
% loaded with four mutually exclusive global options: |voc| (which is
% 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 arguments, like
% so:---
% \begin{compactitem}
% \item \DescribeOption{voc} \cs{arb}|[voc]|\marg{Arabic text};
% \item \DescribeOption{fullvoc} \cs{arb}|[fullvoc]|\marg{Arabic text};
% \item \DescribeOption{novoc} \cs{arb}|[novoc]|\marg{Arabic text};
% \item \DescribeOption{trans} \cs{arb}|[trans]|\marg{Arabic text}.
% \end{compactitem}
%
% 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
% |trans|.

%   And so also: |al-rib_aIT-u| \arb[voc]{al-rib_aIT-u}
%   \arb[trans]{al-rib_aIT-u}.
% \end{quote}
%
% \paragraph{\arb[trans]{\cap{`amruNU}}, and the silent
% \arb[novoc]{U}} To that name a silent \arb[novoc]{U} is added to
% distinguish it from \arb[trans]{\cap{`umar-u}}: see \textcite[i. 12
% C]{Wright}. In no way this affects the sound of the
% \arb[trans]{tanwIn}, so it has to be discarded in |trans| mode:

%
% In some cases, it may be useful to mark the root form of defective

% \subsection{Special orthographies}
% \paragraph{The name of God}
% The name of God, \arb[voc]{al-l_ahu}, is compounded of the article
% \arb[fullvoc]{al-}, and \arb[fullvoc]{'ilAh-u} (noted
% \arb[fullvoc]{'il_ah-u} with the defective \arb[trans]{'alif}) so
% that it becomes \arb[fullvoc]{al-'ilAh-u}; then the
% \arb[trans]{hamzaT} is suppressed, its vowel being transferred to
% the \arb[novoc]{l} before it, so that there remains
% \arb[voc]{alil_ah-u} \parencite[I refer to][I. 83
% col. 1]{Lane}. Finally, the first \arb[novoc]{l} is made quiescent
% and incorporated into the other, hence the \arb[trans]{ta^sdId}
% above it. As \package{arabluatex} never requires a solar letter to
% be written twice (see above, \vpageref{ref:euphonic-tashdid}), the
% name of God is therefore encoded |al-l_ah-u| or |'l-l_ah-u|:---

%
% \subsection{Quoting}
% \label{sec:quoting}
% It is here referred to \enquote{quoting} after the package
% \package{arabtex}.\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{compactenum}[(a)]
% \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" \cap{hinduN}}
%   \arb[trans]{jA'at" \cap{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.du|
%   \arb[novoc]{al-"intiqA.du} \arb[trans]{al-"intiqA.du}.
% \end{quote}
% \end{compactenum}
%
% \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{compactenum}[(a)]
% \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]{\cap{ibn-u} \cap{'abI}
%     \cap{'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{compactenum}
% 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{compactenum}[(a)]
% \item \arb[trans]{'alif-u 'l-wa.sl-i}:---
%   \begin{quote}
%     |fI "istisqA'-a| \arb[voc]{fI "istisqA'-a} \arb[trans]{fI
%     "istisqA'-a}, |wa-"istisqA'-u| \arb[voc]{wa-"istisqA'-u}
%     \arb[trans]{wa-"istisqA'-u}, |qAla| |"uhrub| |fa-lan| |tuqtala|
%     \arb[voc]{qAla "uhrub fa-lan tuqtala} \arb[trans]{qAla "uhrub

% As said above in \vref{ref:hamza}, the \arb[trans]{hamzaT} is always

% \caption*{\Cref*{tab:quoted-hamza}: \enquote{Quoted} \arb[trans]{hamzaT}}
% \end{longtable}
%
% As one can see from \vref{tab:quoted-hamza}, the carrier of the
% \arb[trans]{hamzaT} is inferred from the letter that precedes the
% straight double quote \meta{\texttt{"}}. Of course, any
% \enquote{quoted} \arb[trans]{hamzaT} may take a short vowel, which
% is to be written \emph{after} the Arab\TeX\ equivalent for the
% \arb[trans]{hamzaT} itself, namely \meta{\texttt{'}}. For example,
% \arb[voc]{w"'a} is encoded \meta{\texttt{w"'a}}, while
% \arb[voc]{w"'"} is encoded \meta{\texttt{w"'"}}. In the latter
% example, the second straight double quote encodes the
% \arb[trans]{sukUn} in |voc| mode in accordance with the rule laid
% above \vpagerefrange{ref:quoted-sukun-b}{ref:quoted-sukun-e}.
% \begin{quote}
%   |'a`dA'ukum| \arb[fullvoc]{'a`dA'ukum} \arb[trans]{'a`dA'ukum},

%   \arb[fullvoc]{'a`daA"'|"'ikum} \arb[trans]{'a`dA|"'ikum}.
% \end{quote}
%
% \subsection{The \enquote{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]{\cap{bi-qrAn|nUn-a}}
%   \arb[trans]{\cap{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{\texorpdfstring{Stretching characters: the
% \arb[trans]{ta.twIl}}{Stretching characters: the taṭwīl}}
% \label{sec:tatwil}
% A double hyphen \meta{-\,-} stretches the ligature in which one
% letter is bound to another. Although it is always better to rely on
% automatic stretching, this technique may be used to a modest extent,
% especially to increase legibility of letters and diacritics which
% stand one above the other:--
% \begin{quote}
%   |.hunayn-u| |bn-u| |'is.h--_aq-a| \arb[voc]{.hunayn-u bn-u
%   'is.h--_aq-a} \arb[trans]{\cap{.hunayn-u} bn-u \cap{'is.h--_aq-a}}

% \label{sec:digits}
% \subsubsection{Numerical figures}
% \label{sec:numerical-figures}
% The \emph{Indian numbers}, \arb[trans]{al-raqam-u 'l-hindiyy-u}, are
% ten in number, and they are compounded in exactly the same way as

% \label{sec:abjad}
% The numbers may also be expressed with letters from right to left
% arranged in accordance with the order of the Hebrew and Aramaic
% alphabets \parencite[see][i. 28 B--C]{Wright}. The

% \DescribeMacro{\abjad} \NEWfeature{v.1.1} \arb[trans]{'abjad}
% numbers are inserted with the command \cs{abjad}\marg{number} in any
% of the |voc|, |fullvoc| and |novoc| modes, where \meta{number} may

%   kitAbu-hu fI 'l-`AdAt-i} \arb[trans]{\abjad{45} kitAbu-hu fI
%   'l-`AdAt-i}.
% \end{quote}
% \begin{quoting}
%   \textsc{Rem.}~\emph{a.} As can be seen in the above given example,
%   \package{arabluatex} expresses the \arb[trans]{'abjad} numbers in
%   Roman numerals if it finds the command \cs{abjad} in any of the
%   transliteration modes.
%
%   \textsc{Rem.}~\emph{b.} \cs{abjad} may also be found outside
%   Arabic environments. In that case, \package{arabluatex} does not
%   print the stroke as a distinctive mark over the number for it is
%   not surrounded by other Arabic words. In case one nonetheless
%   wishes to print the stroke, he can use the \cs{aemph} command that
%   is described below in \vref{sec:emphasis}:---
%   \begin{quote}
%     |The| |\arb[trans]{'abjad}| |number| |for| |1874| |is|
%     |\abjad{1874}| The \arb[trans]{'abjad} number for 1874 is

%
% \subsection{Additional characters}
% \label{sec:additional-characters}
% In the manuscripts, the unpointed letters, \arb[trans]{al-.hurUfu

% by various contrivances, as explained in \textcite[i. 4
% B--C]{Wright}. One may find these letters written in a smaller size
% below the line, or with a dot or another mark below. As representing
% all the possible contrivances leads to much complexity and also
% needs to be agreed among scholars, new ways of encoding them will be
% proposed and gradually included as \package{arabluatex} will mature.

% \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 command \cs{aemph}\marg{Arabic
% text} 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 fI 'l-\cap{`AdAt-i}}.
% \end{quote}
%
% \section{Special applications}
% \label{sec:special-applications}
% \paragraph{Linguistics}
% The same horizontal stroke as the \arb[trans]{ta.twIl} (see
% \vref{sec:tatwil}) may be encoded \meta{B}; \meta{BB} will receive
% the \arb[trans]{ta^sdId}. This is useful to make linguistic
% annotations and comments on vowels:---
% \begin{quote}
%   |Bu| |Ba| |Bi| |BuN| |BaN| |BiN| \arb[voc]{Bu Ba Bi BuN BaN BiN}
%   \arb[trans]{Bu Ba Bi BuN BaN BiN}, |BBu| |BBa| |BBi| \arb[voc]{BBu
%   BBa BBi} \arb[trans]{BBu BBa BBi}, |B--aN| \arb[voc]{B--aN}
%   \arb[trans]{B--aN}, |B"| \arb[voc]{B"}\,.
% \end{quote}
%
% \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}, two
% standards are supported at present:
% \begin{compactdesc}
% \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}.}
% \end{compactdesc}
% 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 command
% \cs{SetTranslitConvention}\marg{mode}, where \meta{mode} may be
% either |dmg| or |loc|. This command is also accepted in the preamble
% should one wish to set the transliteration mode globally, eg.:---
% \iffalse
%<*example>
% \fi
\begin{arabluaverbatim}
\usepackage{arabluatex}
\SetTranslitConvention{loc}
\end{arabluaverbatim}
% \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 command
% \cs{SetTranslitStyle}\marg{style}, where \meta{style} may be any
% font shape selection command, eg. \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 may be used for rendering transliterated text:---
% \iffalse
%<*example>
% \fi
\begin{arabluaverbatim}
\newfontfamily\translitfont{Gentium Plus}[Ligatures=TeX]
\SetTranslitFont{\translitfont}
\end{arabluaverbatim}
% \iffalse
%</example>
% \fi
%
% \paragraph{Proper names} \DescribeMacro{\cap} Proper names or book
% titles that must have their first letters uppercased may be passed
% as arguments to the command \cs{cap}\marg{word}. \cs{cap} 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}
%   |\cap{.hunayn-u}| |bn-u| |\cap{'is.h_aq-a}|
%   \arb[voc]{\cap{.hunayn-u} bn-u \cap{'is.h_aq-a}}
%   \arb[trans]{\cap{.hunayn-u} bn-u \cap{'is.h_aq-a}},
%   |\cap{`u_tm_an-u}| \arb[voc]{\cap{`u_tm_an-u}}
%   \arb[trans]{\cap{`u_tm_an-u}}, |.daraba| |\cap{zayd-u}| |bn-u|
%   |\cap{_h_alidiN}| |\cap{sa`d-a}| |bn-a| |\cap{`awf-i}| |bn-i|
%   |\cap{`abd-i}| |\cap{'l-l_ah-i}| \arb[fullvoc]{.daraba
%   \cap{zayd-u} bn-u \cap{_h_alidiN} \cap{sa`d-a} bn-a \cap{`awf-i}
%   bn-i \cap{`abd-i} \cap{'l-l_ah-i}} \arb[trans]{.daraba
%   \cap{zayd-u} bn-u \cap{_h_alidiN} \cap{sa`d-a} bn-a \cap{`awf-i}
%   bn-i \cap{`abd-i} \cap{'l-l_ah-i}}.
% \end{quote}
% However, \cs{cap} 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]{\cap{m}u.hammaduN 'l-nabI} must be
% \arb[trans]{\cap{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: |\cap{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{cap} vz. up to the first letter that is to be
% uppercased, like so: |\cap{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}
%   |\cap{'abU}| |\cap{bakriN}| |\cap{mu\-.ham\-madu}| |bnu|
%   |\cap{za\-ka| |\-riy\-yA'a}| |\cap{'l-rAzI}| \arb{\cap{'abU}
%   \cap{bakriN} \cap{mu\-.ham\-mad-u} bnu \cap{za\-ka\-riy\-yA'a}
%   \cap{'l-rAzI}} \arb[trans]{\cap{'abU} \cap{bakriN}
%   \cap{mu\-.ham\-mad-u} bn-u \cap{za\-ka\-riy\-yA'-a}
%   \cap{'l-rAzI}}.
% \end{quote}
%
% \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{compactenum}[(a)]
% \item \label{ref:dmg-full-rend}In full:
%   \NoArbUp\arb[trans]{\cap{`amruNU}}\ArbUpDflt\,;
% \item \label{ref:dmg-up-rend}As superscript text:
%   \arb[trans]{\cap{`amruNU}}\,;
% \item Discarded: \arb[trans]{\cap{`amr}}.
% \end{compactenum}
% \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} may 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{arabluacode}
\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{arabluacode}
% \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{\arb[trans]{'i`rAb} 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}, |\cap{`amraNU}|
%   \arb[voc]{\cap{`amraNU}} \arb[trans]{\cap{`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}

% \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 command \cs{SetInputScheme}\marg{scheme}, 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{arabluaverbatim}
\usepackage{arabluatex}
\SetInputScheme{buckwalter}
\end{arabluaverbatim}
% \iffalse
%</example>
% \fi
%
% \paragraph{\enquote*{base}, \enquote*{\texttt{xml}} and
% \enquote*{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{\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 single-argument commands
% (\cs{command}\marg{arg}) such as \cs{emph}\marg{text},
% \cs{textbf}\marg{text} and the like, are assumed to have Arabic text
% as their arguments:---
% \begin{quote}
%   |\abjad{45}| |kitAbu-hu| |\emph{fI| |'l-\cap{`AdAt-i}}|
%   \arb[voc]{\abjad{45} kitAbu-hu \emph{fI 'l-\cap{`AdAt-i}}}
%   \arb[trans]{\abjad{45} kitAbu-hu \emph{fI
%   'l-\cap{`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.}
% \end{quote}
% 
% The same applies to footnotes:---
% \iffalse
%<*example>
% \fi
\begin{arabluacode}
\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{arabluacode}
% \iffalse
%</example>
% \fi
%
% Some commands, however, do not expect running text in their
% arguments, or one may wish to insert English text eg. 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.
%
% For example, to distinguish words with a different color, one may
% proceed like so:---
% \iffalse
%<*example>
% \fi
\begin{arabluacode}
\begin{arab}
_tumma "intalaqa _dU 'l-qarn-ayni 'il_A 'ummaT-iN 'u_hr_A fI
\LR{\textcolor{red}{\arb[fullvoc]{((ma.tli`-i 'l-^sams-i))}}}
wa-lA binA'-a la-hum yu'amminu-hum mina 'l-^sams-i.
\end{arab}
\end{arabluacode}
% \iffalse
%</example>
% \fi
%
% \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} may be used to insert English
% footnotes in running Arabic text:---
% \iffalse
%<*example>
% \fi
\begin{arabluacode}
\arb[fullvoc]{\cap{z}ayd-uN\LRfootnote{%
\enquote{\arb[trans]{\cap{z}ayd} is the son of
\arb[trans]{\cap{`a}mr}}: the second
noun is not in apposition to the first, but forms
part of the predicate\ldots} "ibn-u \cap{`a}mr-iNU}
\end{arabluacode}
% \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:---\\
% \arabluaverb{\renewcommand*{\thefootnote}{\textsuperscript{\LR{\arabic{footnote}}}}}
% \DescribeMacro{\FixArbFtnmk} Another solution is to put in the
% preamble, below the line that loads \package{arabluatex}, the
% command \cs{FixArbFtnmk}. However, for more control over the layout
% of footnotes marks, it is advisable to use the package
% \package{scrextend}.\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 command \cs{LRmarginpar} 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.
%
% \DescribeMacro{\setRL} \DescribeMacro{\setLR} \cs{setRL} and
% \cs{setLR} may 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{arabluacode}
\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{arabluacode}
% \iffalse
%</example>
% \fi
%
% \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
% \cs{DeclareQuoteStyle} command, one can define an Arabic style, like
% so:---
% \iffalse
%<*example>
% \fi
\begin{arabluaverbatim}
\usepackage{csquotes}
\DeclareQuoteStyle{arabic}
{\rmfamily\textquotedblright}{\rmfamily\textquotedblleft}
{\rmfamily\textquoteright}{\rmfamily\textquoteleft}
\end{arabluaverbatim}
% \iffalse
%</example>
% \fi
% Then, use this newly defined style with \cs{setquotestyle}, like so:---
% \iffalse
%<*example>
% \fi
\begin{arabluacode}
\setquotestyle{arabic}
\begin{arab}
  fa-qAla la-hu ju.hA: \enquote{.garIb-uN 'amru-ka yA .sadIqI
    'a-tu.saddiqu 'l-.himAr-a wa-tuka_d_diba-nI?}
\end{arab}
\setquotestyle{english}
\end{arabluacode}
% \iffalse
%</example>
% \fi
% \begin{quoting}
%   \textsc{Rem.} Do not forget to set back the quoting style to its
%   initial state once the Arabic environment is closed. See the last
%   line in the code above.
% \end{quoting}
% 
% \subsection{\package{reledmac}}
% \label{sec:reledmac}
% The two-arguments command \cs{edtext}\marg{lemma}\marg{commands} is
% supported inside \cs{begin}|{arab}| \ldots\ \cs{end}|{arab}|. As an
% example, one may get \package{arabluatex} and \package{reledmac} to
% work together like so:---
% \iffalse
%<*example>
% \fi
\begin{arabluaverbatim}
\beginnumbering
\pstart
\begin{arab}
wa-ya.sIru ta.hta 'l-jild-i
\edtext{\arb{.sadId-uN}}{\Afootnote{M: \arb{.sadId-aN} E1}}
\end{arab}
\pend
\endnumbering
\end{arabluaverbatim}
% \iffalse
%</example>

% \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{compactenum}[(a)]
% \item Short-term:
%   \begin{compactenum}[i.] 
%   \item Support for typesetting Arabic poetry.
%   \item The \arb[trans]{\cap{qur'An}}: support for typesetting the
%     \arb[trans]{\cap{Qur'An}}.
%   \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{compactenum}
% \item Medium-term:
%   \begin{compactenum}[i.]
%   \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}.
