% \section{Introduction}
% \subsection{Motivation}
%
% The acronym \acro{Moodle} stands for ``Modular Object-Oriented Dynamic Learning Environment.''
% It is an open source learning management system (\LMS) employed by many universities,
% colleges, and high schools to provide digital access to course materials, such as
% notes, video lectures, forums, and the like; see
% \url{https://moodle.com/moodle-lms/} for more information.
% One of the many useful
% features of \Moodle\ is that mathematical and scientific notation can be entered in
% \LaTeX\ or \TeX\ code, which will be typeset either through a built-in \TeX\ filter
% or by invoking MathJax.
%
% For instructors who want to give students frequent feedback,
% but lack the time to do so, a particularly valuable module in \Moodle\
% is the \emph{quiz}.  A \Moodle\ quiz can consist of several different types of
% questions---not only multiple choice or true/false questions, but also
% questions requiring a short phrase or numerical answer, and even essay
% questions.  All but the essay questions are automatically graded by the
% system, and the instructor has full control over how often the quiz may be
% attempted, its duration, and so forth.  Feedback can be tailored to specific
% mistakes the student makes.
%
% All these features make \Moodle\ quizzes very useful tools for instructors
% who have access to them.
% Unfortunately, the primary way to create or edit a \Moodle\ quiz
% is through a web-based interface that can be slow to operate.
% To users of \LaTeX, accustomed to the speed of typing source code on
% a keyboard alone, the agonizing slowness of switching between mouse and keyboard
% to navigate a web form with its myriad dropdown boxes, radio buttons,
% compounded with a perceptible time lag as one's \Moodle\ server responds to requests,
% can produce a very frustrating experience.  Moreover, editing is entirely
% impossible without network access.
%
% Once the quiz is written, there is no easy way to view and proofread all the
% information of which it is made.  Each question is edited on a separate webpage,
% which is so full of options that it cannot be viewed on a single screen.
% An instructor has to spend much time checking over the newly created quiz in
% order to be confident there are no errors.
%
% Added to all this is the frustration of managing graphics.
% If a question requires an image---say, asking a calculus student to interpret
% the graph of a function---the image must first be produced as a standalone file
% (e.g., in \JPG\ or \PNG\ format), uploaded to \Moodle, and then chosen in a web-based
% \HTML\ editor.  Great is the vexation of the instructor who decided to alter a
% question, as there are more and more possibilities of error whenever multiple
% files must be kept synchronized.
%
% Users of \LaTeX\ are also accustomed to the speed and flexibility that
% comes from defining their own macros, which may be as brief as writing
% \cmd{\R} instead of |\mathbb{R}|
% or as complex as macros that generate entire paragraphs of text.
% The \Moodle\ editor, by contrast, requires you to type |\mathbb{R}|
% every single time you want $\mathbb{R}$.
%
% Finally, there is the question of archiving and reusing one's work.
% Much, much work goes into creating \Moodle\ quizzes, which then reside
% on a \Moodle\ server somewhere in the cloud in a format neither easily browsable
% nor easily modifiable.
%
% \LaTeX\ itself has the power to solve all these difficulties:
% it is swift to edit and swifter to compile a \LaTeX\ document,
% and the \PDF\ may be previewed onscreen or printed out for ease of proofreading.
% Mathematical graphics can be integrated within the main file through \TikZ,
% and of course \LaTeX\ macros can be customized.
% Using the present \pkg{moodle} package,
% a quiz author can type a quiz using familiar \LaTeX\ syntax and document
% structure.  Upon compilation, \LaTeX\ will generate both a well-organized
% \PDF\ that is easy to proofread and an \XML\ file that can be uploaded directly
% to \Moodle.  The entire process is far faster than using \Moodle's own
% web-based editor, makes it easier to catch one's mistakes,
% and the ultimate source code of one's work is a human-readable \filenm{.tex} file
% that can be archived, versioned, browsed, and edited offline.
%
% Strictly speaking, the \pkg{moodle} package does not generate quizzes:
% it generates question banks that can be imported in the \LMS. The teacher
% still needs to compose manually a quiz from the question banks. Hopefully,
% two \Moodle\ features supported by the package make this task easier:
% categories and tags.
%
% In this documentation the \LMS\ is referred to as \Moodle\
% (uppercase letters and roman font) while the \LaTeX\ package
% is referred to as \pkg{moodle} (lower case and sans serif font).

% \end{figure}
%
% The process of creating a quiz in \Moodle\ using this package is depicted in
% Figure~\vref{fig:workflow}. It follows a few
% steps:
% \begin{enumerate}
%   \item Write a \LaTeX\ document using |\usepackage{moodle}| as described
% below.
%   \item Compile the document to \PDF\ using pdf\LaTeX\ (\acro{ASCII} characters only),
%         \XeLaTeX, or \LuaLaTeX.
% This will also produce the file \meta{jobname}\filenm{-moodle.xml}.
%   \item navigate to your course on \Moodle\ and, under ``Question bank'', select ``Import.''
%   \item Select ``Moodle \XML\ format,'' choose the \XML\ file to upload, and press ``Import.''
%   \item After \Moodle\ verifies that the questions have been imported correctly,
%         you may add them to your quizzes.
% \end{enumerate}
%
% \section{Usage}\label{sect:usage}
% The following pages presume the reader already has some familiarity with creating
% and editing \Moodle\ quizzes through the web interface.
% Users that are not familiar with \Moodle\ quizzes can learn more in the \Moodle\
% documentation. For instance, \url{https://docs.moodle.org/en/Question_types}.
%
% The \pkg{xkeyval} package is used to provide a key-value interface.
%
% \subsection{Example Document}
%
% Here is a simple example document:
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \documentclass[12pt]{article}
%   \usepackage[section]{moodle}
%   \moodleregisternewcommands
%   \newcommand\monomial[1]{x^{#1}}
%   \newcommand\sillyanswer{What!?}
%   \begin{document}
%   Quiz generated \LaTeX's \textsf{moodle} (\moodleversion, \moodledate).
%   Import the derived file \texttt{\jobname-moodle.xml} on Moodle.
%   \begin{quiz}{My first quiz}
%     \begin{numerical}[points=2]{Basic addition}
%       What is $8+3$?
%       \item 11
%     \end{numerical}
%     \begin{shortanswer}[usecase]{Newton's name}
%       What was Newton's first name?
%       \item Isaac
%       \item[fraction=0, feedback={\sillyanswer}] Fig
%       \item[fraction=0] Sir
%     \end{shortanswer}
%     \begin{multi}[points=3]{A first derivative}
%       What is the first derivative of $\monomial{3}$?
%       \item $\frac{1}{4}\monomial{4}+C$
%       \item[feedback={yes!}]* $3\monomial{2}$
%       \item[feedback={\sillyanswer}]  $51$
%     \end{multi}
%   \end{quiz}
%   \end{document}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
% Key features to note in this first example are that a \env{quiz} environment
% contains several question environments.
% Each question takes a name as a mandatory argument,
% and it may also take optional key-value arguments within brackets.
% The question environments resemble list environments
% such as \env{itemize} or \env{enumerate}, in that answers are set off by
% \cmd{\item}'s, but the question itself is the text that occurs before
% the first \cmd{\item}.
%
%^^A \DescribeMacro[moodle]{\moodleregisternewcommands}
%^^A \DescribeMacro[moodle]{\htmlregister}
%^^A Calling \cmb{\moodleregisternewcommands} tells the package to treat
%^^A specifically the macros defined subsequently.
%^^A This way, the macros that \Moodle's \LaTeX\ renderer does not know
%^^A about can be properly expanded in the \XML\ file.
%^^A This mechanism applies only to the macros defined using \cmd{\newcommand}
%^^A and \emph{without} optional argument.
%^^A Using \cmd{\htmlregister}\marg{macroname}, lets you declare a specific
%^^A macro for expansion. This mechanism, instead, also applies to the
%^^A macros defined using \TeX's primitive \cmd{\def}.
%
% \subsection{Package Options}
%
% \DescribeOption[moodle]{draft} If the package option \optn{draft} is invoked,
% by calling |\usepackage[draft]{moodle}| or |\documentclass[draft]{...}|,
% then no \XML\ file will be generated. This is especially useful while
% editing a quiz containing graphics, so as to avoid the time spent
% converting image files.
% \DescribeOption[moodle]{final} The package option \optn{final} might be
% useful if one wants to avoid the option \optn{draft} to be inherited from
% the \cmd{\documentclass}.
%
% \DescribeOption[moodle]{handout}
% If the package option \optn{handout} is invoked (|\usepackage[handout]{moodle}|),
% the \PDF\ file is generated clean from teacher-only information (answers,
% points, penalty, feedback, tags) and, hence, can be given  to students
% for classroom work. In particular, as would \Moodle\ do, answers in
% \env{matching} questions are shuffled and the option \optn{shuffle}
% triggers the shuffling of choices offered (\env{multi} and
% \env{matching}). This is achieved thanks to the package
% \pkg{randomlist}, loaded if the option is invoked. The seed of its
% random generator is controlled by the macro \cmd{\RLsetrandomseed}\marg{integer}
% \DescribeMacro[randomlist]{\RLsetrandomseed}.
% This option does not interfere with the generation of the \XML\ file.
%
% \DescribeOption[moodle]{samepage}^^A\watchout[experimental]
% If the package option \optn{samepage} is invoked, preferably used together
% with \optn{handout} (|\usepackage[handout,samepage]{moodle}|), the package
% will try to keep every question on the same page. Very bad spacing
% can result from this.
% This option is experimental. Subquestions inside a \env{cloze} question
% are protected but the \env{cloze} question itself is not protected.
%
% \DescribeOption[moodle]{nostamp}
% By default, the package will output a stamp as a comment in the XML
% file. This stamp contains information gathered about the \TeX\ engine,
% the platform used and the package version. For instance:%
% \begin{quote}\small
% \makeatletter\def\today{\the\year-\two@digits\month-\two@digits\day}\makeatother
% \newcount\hour\hour=\time
% \divide\hour by 60\relax
% \newcount\minute\minute=\hour
% \multiply\minute by -60\relax
% \advance\minute by \time\relax
% |<!-- This XML file is a question bank made for Moodle. -->|\\
% |<!-- It was generated on |\texttt{\today\space\the\hour:\the\minute}| by LuaLaTeX running -->|\\
% |<!-- on Linux with the package moodle |\texttt{\fileversion}| (|\texttt{\filedate}|) -->|
% \end{quote}
% The package option |nostamp| prevents this
% stamp from being written in the \XML\ file.
%
% \DescribeOption[moodle]{section}\DescribeOption[moodle]{subsection}
% \DescribeOption[moodle]{section*}\DescribeOption[moodle]{subsection*}
% The package options \optn{section} and \optn{subsection} place each quiz as a
% new section or subsection, respectively. Starred variants
% correspond to unnumbered sections or subsections. To preserve
% compatibility with Version 0.5 of this package, the default is
% \optn{subsection*}. Consequently, |\usepackage[subsection*]{moodle}| is equivalent
% to |\usepackage{moodle}| .
%
% \DescribeOption[moodle]{tikz}
% The package option \optn{tikz} is described in Section~\vref{subsec:tikz}.
%
% \DescribeOption[moodle]{svg}^^A\watchout[experimental]
% The package option \optn{svg} is described in Section~\vref{subsec:svg}.
%
% \DescribeOption[moodle]{LMS}\texttt{=}\meta{\texttt{X.Y}}
% \DescribeDefault{warn only} lets you specify version numbers
% for the target \Moodle\ LMS instance (\texttt{X} and \texttt{Y} are
% major and minor version integers). When version numbers are provided,
% the use of recent quiz features is secured by a compatibility
% check and \pkg{moodle} raises relevant errors. The XML stamp
% (see \optn{nostamp} above) also mentions \Moodle's target version.
% By default, \pkg{moodle} will just issue warnings when recent quiz
% features are used.
%
% \subsection{Quiz and Question Environments}
%
% A \filenm{.tex} document to generate \Moodle\ quizzes contains one or more
% \env{quiz} environments.
%
% \DescribeEnv[moodle]{quiz}\oarg{common options}\marg{category name}
% defines a quiz, within which various question environments are nested.
% The mandatory argument, \meta{category name}, names a category for \Moodle's
% ``question bank'': after import, the questions defined in this environment
% will be gathered in this category.
% Using the optional argument, options can be set at the quiz level.
% Although there are no \env{quiz}-specific options, any \meta{common options} set
% with the quiz will be inherited by all questions contained within that environment.
%
% \DescribeMacro[moodle]{\moodleset}\marg{options}
% is to be used to set options outside question environments; the option
% settings are local to \TeX-groups.
%
% \DescribeMacro[moodle]{\setcategory}\marg{category name}
% is to be used to change the current category inside a quiz environment and
% in between questions. Note that the \env{quiz} environment defines a category
% by its own.
%
% \DescribeMacro[moodle]{\setsubcategory}\marg{subcategory name}
% does the same with subcategories.

% The categories and subcategories are reflected in the \PDF\ file as sections, subsections, or
% subsubsections, in accordance to the package setting \optn{section}, \optn{section*},
% \optn{subsection}, or \optn{subsection*}.
%
% The syntax for each question environment is
% \begin{quote}
%   |\begin|\marg{question type}\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item|\oarg{item options} \meta{item} \\
%   \rule{2em}{0pt}\quad$\vdots$ \\
%   \rule{2em}{0pt}|\item|\oarg{item options} \meta{item} \\
%   |\end|\marg{question type}
% \end{quote}
% The meaning of the \meta{item}s varies depending on the question type,
% but they usually are answers to the question.
% Details will be given below.
%
% The following key-value options may be set for all questions:
%
% \DescribeKey[quiz,question]{points}\DescribeDefault{1}
% \DescribeKey[quiz,question]{default grade}
% By default, each question is worth 1 point on the quiz.
% This setting may be changed with the \optn{points} key or its synonym, \optn{default grade}.
% For example, \optn{points=2} makes that question worth two points.
%
% \DescribeKey[quiz,question]{penalty}\DescribeDefault{0.1}
% The \optn{penalty} is the fraction of points that is taken off for each wrong attempt;
% it may be set to any value between 0 and 1.
%
% \DescribeKey[answer]{fraction}^^A\DescribeDefault{0}
% In most question types, it is possible to designate some answers as being
% worth partial credit---that is, some fraction of a completely correct answer.
% The \optn{fraction} key may be set to any of the values given in Table~\vref{tab:fraction},
% from \texttt{0} (entirely wrong) to \texttt{100} (entirely correct).

%
% In questions where several choices can be selected (see \env{multi} with option
% \optn{multiple}), positive fractions must add up to exactly 100. It is also possible to set
% negative fractions (from -100 to 0) for wrong choices, in order to prevent the
% selection of all choices from leading to a good grade.
% In this case, the value ranging from -100 to 0 must be the opposite of one of the
% values listed in Table~\vref{tab:fraction}.
%
% \DescribeKey[answer]{fractiontol}\DescribeDefault{0.01}
% The package tries to match the \optn{fraction} key to one of the admissible values.
% To this end, the tolerance is controlled by the \optn{fractiontol} key. The default
% value, \texttt{0.01}, may be changed. When no admissible fraction value is matched, the
% package raises an error.
%
% \DescribeKey{feedback}
% The \optn{feedback} key sets text that will appear to the student after completing the quiz.
% For example, one might set
% \begin{center}
%   |feedback={This question might show up in the final exam.}|
% \end{center}
% The desired feedback should be included in braces.
%
% \DescribeKey[question]{feedback}If the \optn{feedback} key is set for a question,
% then that feedback will appear to each student regardless of the student's answer.
%
% \DescribeKey[answer]{feedback}
% Answer-specific feedback (perhaps explaining a common mistake)
% may also be given by setting the \optn{feedback} key \emph{at the individual answer}.
%
% \DescribeKey{tags}
% The \optn{tags} key sets a list of keywords for the question that will be taken into account
% by \Moodle\ for filtering purposes or classification of questions inside the question bank.
% It is possible for instance to build a quiz with questions cherry-picked among the set of
% questions holding a particular tag.
% For example, one might set
% \begin{center}
%   |tags={easy}|
% \end{center}
% The desired tag should be specified in between braces. Multiple tags can be set as a
% comma-separated list:
% \begin{center}
%   |tags={tag1,tag2,{ leading whitespace},{including, comma}}|
% \end{center}
%
% \DescribeKey[quiz]{tags}
% If the \optn{tags} key is set at the quiz level,
% then that tag list will serve as a default for each question of the quiz.
%
% \DescribeKey[question]{tags}
% Question-specific tags can be assigned by setting the \optn{tags} key \emph{at the question level}.
% The question-level \optn{tags} key overrides eventual quiz-level tags.
%
% Users willing to specify a same tag for all questions of the quiz could
% also consider relying on \Moodle's category mechanism.
%
% \subsection{\href{https://docs.moodle.org/en/Question_types}{Question Types}}
%
% We next discuss the various question types supported by \pkg{moodle}
% and the options that may be set.
%
%\subsubsection{\href{https://docs.moodle.org/en/True/False_question_type}{True/False}}
%
% \DescribeEnv[quiz]{truefalse}\oarg{question options}\marg{question name}
% is an environment that defines a \emph{True/False} question.
%
% The syntax for a True/False question is as follows:
% \begin{quote}
%   |\begin{truefalse}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item*| \meta{feedback when ``true" is chosen} \\
%   \rule{2em}{0pt}|\item| \meta{feedback when ``false" is chosen} \\
%   |\end{truefalse}|
% \end{quote}
% The correct answer is designated by the asterisk \texttt{*} after the \cmd{\item};
% it need not appear first in the list.
%
% Answer-specific feedback can also be defined as an item option, similarly to
% other types.
% \begin{quote}
%   |\begin{truefalse}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item[feedback={|\meta{When ``true" is chosen}|}]*| \\
%   |\end{truefalse}|
% \end{quote}
% Note that, in this example, no feedback is defined for the incorrect answer
% ``False": the corresponding item can be omitted.
%
% With the True/False question type, the |penalty| key has no effect.
%
% \subsubsection{\href{https://docs.moodle.org/en/Multiple_Choice_question_type}{Multiple Choice}}
% \label{subsec:multi}
%
% \DescribeEnv[quiz]{multi}\oarg{question options}\marg{question name}
% is an environment that defines a \emph{Multiple Choice} question.
%
% The syntax for a classic multiple choice question,
% with only one correct answer, is as follows:
% \begin{quote}
%   |\begin{multi}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item|\oarg{answer options}|*| \meta{correct answer} \\
%   \rule{2em}{0pt}|\item|\oarg{answer options} \meta{wrong answer} \\
%   \rule{2em}{0pt}\quad$\vdots$ \\
%   \rule{2em}{0pt}|\item|\oarg{answer options} \meta{wrong answer} \\
%   |\end{multi}|
% \end{quote}
% The correct answer is designated by the asterisk \texttt{*} after the \cmd{\item};
% it need not appear first in the list.
%
%
% \DescribeBoolean[multi]{shuffle}\DescribeDefault{true}
% The Boolean key \optn{shuffle} determines whether \Moodle\ will
% rearrange the possible answers in a random order.
% Setting \optn{shuffle=false} will guarantee that the answers will
% be presented to the student in the order they were typed.
%
% \DescribeKey[multi]{numbering}\DescribeDefault{abc}
% \Moodle\ offers different options for numbering the possible answers.
% You may set the \optn{numbering} key to any of the values listed in
% Table~\vref{tab:numbering_options}.
% \begin{table}[tbp]
% \centering
% \caption{Numbering modalities offered for \env{multi} questions.}
% \label{tab:numbering_options}
% \begin{tabular}{rllllll}
% \toprule
% Sample & a., b., \dots & A., B., \dots & 1., 2., \dots & i., ii., \dots &
% I., II., \dots & $\bullet$ \\
% \cmidrule(lr){2-2}\cmidrule(lr){3-3}\cmidrule(lr){4-4}\cmidrule(lr){5-5}\cmidrule(lr){6-6}
% \cmidrule(lr){7-7}
% \LaTeX\ syntax & \optn{alph} & \optn{Alph} & \optn{arabic} & \optn{roman} & \optn{Roman} & \optn{none}\\
% \Moodle\ syntax & \optn{abc} & \optn{ABCD} & \optn{123} & \optn{iii} & \optn{IIII} & \optn{none} \\
% \bottomrule
% \end{tabular}
% \end{table}
% \optn{numbering=none} produces an unnumbered list of answers.
% Note the \emph{four} capital letters required by \Moodle's syntax
% to obtain upper-case Roman or alphabetic numerals.
%
% \DescribeKey[item]{fraction}\DescribeDefault{0}
% \DescribeKey[item*]{fraction}\DescribeDefault{100}
% The \optn{fraction} key may be automatically set depending on the
% presence of an asterisk \texttt{*} right after the \cmd{\item}. By default,
% Starred items designate correct answers (\optn{fraction=100}) while
% bare items designate incorrect answers (\optn{fraction=0}).
% The key can be used to designate some wrong answers as being worth
% partial credit or sanction.  For example, a question might read
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{multi}{my question}
%     Compute $\int 4x^3\,dx$.
%     \item* $x^4+C$
%     \item[fraction=50] $x^4$
%     \item $12x^2$
%   \end{multi}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
%
% \DescribeBoolean[multi]{single}\DescribeDefault{true}
% By default, the \env{multi} environment produces a multiple choice
% question where only one answer can be selected. This is called
% \optn{single} mode.
%^^A On \Moodle, the choices are displayed with radio
%^^A buttons and only one of them can be selected by the student.
%
% In \optn{single} mode, the teacher can set negative fractions for
% incorrect choices. This way, the expected grade of a student
% picking up choices randomly across a quiz is lowered.
% By default, incorrect answers that do not have a fraction
% specified correspond to \optn{fraction=0}.
% \DescribeKey[quiz,multi]{sanction}\DescribeDefault{0} However,
% if the \optn{sanction} key is set to a positive value, at quiz or
% question levels, such incorrect answers are sanctioned as if
% \optn{fraction=-}\meta{sanction value} was set for each of them.
%
% \DescribeKey[multi]{multiple}
% It is also possible to write questions with possibly more than
% one correct answer, asking the user to check all correct answers.
% To do this, use the key \optn{multiple} or \optn{single=false}.
% For this kind of question, the student gets a grade that
% corresponds to the total of the weights of the answers selected.
% Users may rely on two modalities to set the weights of the answers:
% \begin{enumerate}
% \item the \emph{advanced mode} applies whenever a \optn{fraction} key
% is set among the proposed answers. In this case, it is recommended
% that the user sets manually everything. Answers that are left with
% no fraction set are considered as neutral, selecting them will
% not change the grade. If \cmd{\item*} is used to designate some correct
% answers, \pkg{moodle} will distribute equally among those answers
% the points that are left for a total of 100\% (only positive
% fractions count here). Note that doing so will easily yield
% situations where the weights are inadmissible (see
% Table~\vref{tab:fraction}).
% \item the \emph{automatic mode} applies when correct answers are
% designated using \cmd{\item*} and no answer has a \optn{fraction} key set.
% In this case, each correct answer is weighted to bring the same
% fraction of the maximum grade and each incorrect answer is
% weighted to cancel the benefits of the selection of one correct
% answer.
% \end{enumerate}
% For example, the following two examples are equivalent:
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{multi}[multiple]{Automatic Mode}
%     Which numbers are prime?
%     \item 2
%     \item* 5
%     \item* 7
%     \item 1
%     \item 6
%   \end{multi}
%   \begin{multi}[multiple]{Advanced Mode}
%     Which numbers are prime?
%     \item[fraction=-50] 2
%     \item[fraction=50] 5
%     \item[fraction=50] 7
%     \item[fraction=-50] 1
%     \item[fraction=-50] 6
%   \end{multi}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
% Note that, in this example, negative fractions are set for wrong
% choices. This prevents students from obtaining a good grade with
% no merit if they select all answers.
%
% Contrarily to the \optn{single} mode where questions with negative fractions may
% lead to a overall negative grade, when multiple choices can be selected, the
% lowest grade \Moodle\ will take into account for the question is 0.
%
% \DescribeKey[multi]{allornothing}
% There also exists a \href{https://moodle.org/plugins/qtype_multichoiceset}
% {``All-or-Nothing Multiple Choice''} plugin for \Moodle\ that introduces a
% question type similar to a multiple choice with multiple correct answers,
% with the specificity that the points are given if and only if the student
% selects all correct answers. This kind of question is set up using the
% \optn{allornothing} key.
% The recommended way for designating correct answers is with \cmd{\item*}. If instead
% the \optn{fraction} is used, \pkg{moodle} will consider that non-negative
% fractions ($>0$) designate correct answers and negative fractions ($\leq 0$)
% designate incorrect choices.
% The option \optn{allornothing} supersedes the options \optn{multiple} and \optn{single}.
% To the best of our knowledge, \Moodle\ does not offer the all-or-nothing behavior
% for multiple choice questions embedded inside a \env{cloze} question.
%
% \subsubsection{\href{https://docs.moodle.org/en/Numerical_question_type}{Numerical}}
%
% \DescribeEnv[quiz]{numerical}\oarg{question options}\marg{question name}
% is an environment that defines a \emph{Numerical} question which, in \Moodle, requires the student
% to input a real number in decimal form.
%
% The typical format for this question type is:
% \begin{quote}
%   |\begin{numerical}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item|\oarg{answer options} \meta{correct answer} \\
%   |\end{numerical}|
% \end{quote}
% If there is more than one correct answer, additional \cmd{\item}'s may be included.
% Because this is not a multiple choice question, there is no need to provide
% incorrect answers. There may nevertheless be reasons to include incorrect answers.
% For example, partially correct answers may be specified by setting the \optn{fraction} key.
% Feedback for a common mistake may be given by including the incorrect answer like this:
% \begin{quote}\footnotesize
%   |\item[fraction=0,feedback={Forgot to antidifferentiate?}]| \meta{incorrect answer}
% \end{quote}
%
% \DescribeKey[numerical]{tolerance}\DescribeDefault{0}
% The \optn{tolerance} key can be used to specify the validity of answers within some margin.
% This key can be set at different levels: quiz, question, item.
% For example, with the question
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{numerical}[tolerance=0.01]{my question}
%     Approximate value of $\sqrt{2}$?
%     \item[tolerance={1e-1}] 1.4142
%     \item[fraction=20,feedback={twice this!}] 7.0711e-1
%     \item[fraction=0,feedback={Wrong!}] *
%   \end{numerical}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
% In this example,
% \begin{itemize}
%   \item any answer in the range $[1.4042,1.4242]$ will be validated,
%   \item any answer in the range $[0.69711,0.71711]$ will get the specific feedback
%         \emph{twice this!} and 20\% of points,
%   \item any other answer is incorrect and will get the specific feedback
%         \emph{Wrong!}.
% \end{itemize}
%
% When feedback is to be given for any non-specified answer, one can add a \emph{last} answer
% item containing the wildcard character \texttt{*} only. In this case, the \optn{tolerance} key is irrelevant.
%
% Both answers and tolerance can be specified with the comma (\texttt{,}) as a decimal separator.
% Exponent notation is accepted. After import, \Moodle\ will recognize indifferently \texttt{0.000165},
% \texttt{0,000165}, \texttt{1.65E-4}, \texttt{1.65e-4}, \texttt{1,65E-4}, and \texttt{1,65e-4}.
%
% If the \pkg{siunitx} package is loaded, \pkg{moodle} will detect it and
% numbers will be rendered nicely in the \PDF\ output.
%
% Units, unit-handling and multipliers are currently unsupported.\watchout
%
% \subsubsection{\href{https://docs.moodle.org/en/Short-Answer_question_type}{Short Answer}}
%
% \DescribeEnv[quiz]{shortanswer}\oarg{question options}\marg{question name}
% is an environment that defines a \emph{Short Answer} question. It resembles
% a \env{numerical} question: the student is to fill in a text box with a
% missing word or phrase.
% \begin{quote}
%   |\begin{shortanswer}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item|\oarg{answer options} \meta{correct answer} \\
%   \rule{2em}{0pt}\quad$\vdots$ \\
%   \rule{2em}{0pt}|\item|\oarg{answer options} \meta{correct answer} \\
%   |\end{shortanswer}|
% \end{quote}
% You can make the text box appear as part of the question with the
% control sequence \cmd{\blank}.  For example,
% your question might read
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{shortanswer}{Leibniz}
%     Newton's rival was Gottfried Wilhelm \blank.
%     \item Leibniz
%     \item Leibniz.
%   \end{shortanswer}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
% Note that as the blank occurred at the end of a sentence,
% we included two answers,
% lest students get the question wrong merely by
% including or omitting a period.
%
% \DescribeBoolean[shortanswer]{case sensitive}\DescribeDefault{false}
% The default setting when creating a Short Answer question in \Moodle\
% is to ignore the distinction between upper- and lower-case letters
% when grading a short answer question. This default is preserved by
% \pkg{moodle}.
% You can make a question case-sensitive with the Boolean key
% \optn{case sensitive} or its shorter synonym \optn{usecase}\DescribeBoolean[shortanswer]{usecase}.
%
% The \href{https://docs.moodle.org/en/Short-Answer_question_type#Wildcard_usage}%
% {wildcard character} \texttt{*} can used to grab answers that match
% a specific pattern. Following the order of answers, the first match will lead
% to the corresponding score and eventual feedback. As an example, take the
% following question
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{shortanswer}[usecase]{Newton's name}
%     What was Newton's first name?
%     \item Isaac
%     \item[fraction=0,feedback={Simply Isaac!}] Isaa*
%     \item[fraction=0,feedback={This one is Leibniz!}] *Gottfried*
%     \item[fraction=0,feedback={First name, not title!}] Sir*
%     \item[fraction=0,feedback={No\dots}] *
%   \end{shortanswer}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
% \begin{itemize}\def\answ#1{\framebox{\texttt{#1}}}%
%   \item the answer \answ{Isaac} is the only one that gets rewarded,
%   \item answers \answ{Isaac Leibniz}, \answ{Isaac Newton}, and \answ{Isaak} yield
%   the feedback \emph{Simply Isaac!},
%   \item answers \answ{Sir Gottfried Wilhelm}, \answ{Sir Gottfried},
%         \answ{Gottfried Wilhem}, and \answ{Gottfried} yield
%         the feedback \emph{This one is Leibniz!},
%   \item answers \answ{Sir Isaac}, and \answ{Sir} yield
%         the feedback \emph{First name, not title!},
%   \item any answer that does not match the previous patterns
%         yields the feedback \emph{No\dots}.
% \end{itemize}
%
% \subsubsection{\href{https://docs.moodle.org/en/Essay_question_type}{Essay}}\label{subsubsect:essay}
%
% \DescribeEnv[quiz]{essay}\oarg{question options}\marg{question name}
% is an environment that defines an \emph{Essay} question.
%
% Instructors may ask essay questions on a \Moodle\ quiz,
% although \Moodle's software is not up to the task of grading them!
% Instead, each essay question answer must be graded manually by the
% instructor or a teaching assistant.
% \begin{quote}

%   \rule{2em}{0pt}\quad$\vdots$ \\
%   \rule{2em}{0pt}|\item| \meta{information $n$ for grader} \\
%   |\end{essay}|
% \end{quote}
% Instead of containing answers, the \cmd{\item} entries included in the \env{essay}
% question contain notes that will appear to whoever is grading the question manually.
% Contrarily to other question types, \cmd{\item} in \env{essay} questions
% do not take options.
%
% \DescribeBoolean[essay]{response required}\DescribeDefault{false}
% Although \Moodle\ cannot grade the content of an essay question,
% it can at least determine whether the question has been left blank.
% If the \optn{response required} key is set, \Moodle\ will insist that the student
% enter something in the blank before accepting the quiz as completed.
%
% \DescribeKey[essay]{response format}\DescribeDefault{html}
% \Moodle\ offers five different ways for students to enter and/or upload their
% answers to an essay question. You may choose one of these five options:
% \begin{description}
%   \ItemDescribeOther[response format]{html} An editor with the ability to format \HTML\ responses
%         including markup for italics, boldface, etc.  This is the default.
%   \ItemDescribeOther[response format]{file} A file picker allowing the student to upload a
%         file, such as a \PDF\ or DOC file, containing the essay.
%   \ItemDescribeOther[response format]{html+file} The same \HTML\ editor as above, but with the
%         ability to upload files as well.  This permits some students to type
%         answers directly into the web form, and others to compose their
%         essays in another program first.
%   \ItemDescribeOther[response format]{text} This editor allows only for entering plain text
%         without any markup.
%   \ItemDescribeOther[response format]{monospaced} This yields a plain text editor, without any
%         markup, and with a fixed-width font.  This could be useful for
%         entering code snippets, for example.
% \end{description}
%
% \DescribeKey[essay]{response field lines}\DescribeDefault{15}
% The key \optn{response field lines} controls the height of the input box.
% For \Moodle, the admissible values are: 5, 10, 15, 20, 25, 30, 35, and 40.
% If the value set is not admissible, \pkg{moodle} will approximate the value:
% \begin{itemize}
%   \item with either 5 or 40 if the value set was out of range, or
%   \item with the next multiple of 5 otherwise.
% \end{itemize}
%
% \DescribeKey[essay]{attachments allowed}\DescribeDefault{0}
% The \optn{attachments allowed} key controls \emph{how many} attachments a student is
% allowed to upload. Admissible values are \texttt{0}, \texttt{1}, \texttt{2},
% \texttt{3}, or \texttt{unlimited}.
%
% \DescribeKey[essay]{attachments required}\DescribeDefault{0}
% You may also require the student to upload a certain number of attachments
% by setting \optn{attachments required} to \texttt{0}, \texttt{1}, \texttt{2}, or \texttt{3}.
%
% \DescribeKey[essay]{template}
% Finally, you may preload the essay question with a template that the student
% will edit and/or type over, with the key \optn{template=}\marg{template}.
% The \meta{template} should be enclosed in braces.
%
% \subsubsection{\href{https://docs.moodle.org/en/Matching_question_type}{Matching}}
%
% \DescribeEnv[quiz]{matching}\oarg{question options}\marg{question name}
% is an environment that defines a \emph{Matching} question. It typically
% looks like this:
% \begin{quote}
%   |\begin{matching}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   \rule{2em}{0pt}|\item| \meta{item 1} |\answer| \meta{match 1}\\

%   |\end{matching}|
% \end{quote}
% \meta{match}es $1$ through $m$ are separated from their corresponding
% \meta{item}s by the command \cmd{\answer}\DescribeMacro[matching]{\answer}.
% Answers that match no item can be proposed at the end of the list,
% preceded by an empty item.
%
% After import, \Moodle\ will recognize matches that are \emph{exact}
% duplicates. If you intend multiple questions to have the same match,
% make sure that they are entered identically.
%
% \DescribeBoolean[matching]{shuffle}\DescribeDefault{true}
% When students take a matching question, \Moodle\ always displays
% the proposed matches in random order.
% The \env{matching} question accepts the option |shuffle| to also
% randomly permute the items.
%
% \DescribeBoolean[matching]{drag and drop}\DescribeDefault{false}
% The standard matching question offered by \Moodle\ corresponds to
% a dropdown box for choosing the match for each item.
% There also exists a \href{https://docs.moodle.org/en/Drag_and_drop_matching_question_type}
% {``drag and drop matching''} plugin for \Moodle\ that
% shows all items in a column (left), all proposed matches in a second column

% match to each item with the mouse.
% In this package, to enable drag-and-drop matching, use the key
% \optn{drag and drop} or \optn{dd}\DescribeKey[matching]{dd}\ for short.
% Beware that, with the standard format (\optn{drag and drop=false}), due
% to the limitations of dropdown boxes, \Moodle\ will not render \LaTeX\

% A ``cloze question'' has one or more subquestions embedded within a passage of text.
% For example, you might ask students to fill in several missing words within
% a sentence, or calculate several coefficients of a polynomial.
% To encode cloze questions in \LaTeX\ using this package is easy:
% you simply nest one or more \env{multi}, \env{numerical}, or \env{shortanswer} environments
% within a \env{cloze} environment, as in the following example:
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{cloze}{my cloze question}
%     Thanks to calculus, invented by Isaac
%     \begin{shortanswer}[usecase]
%       \item Newton
%     \end{shortanswer},
%     we know that the derivative of $x^2$ is
%     \begin{multi}[horizontal]
%       \item $2x$
%       \item* $\frac{1}{3} x^3 + C$
%       \item $0$
%     \end{multi}
%     and that $\int_0^2 x^2\,dx$ equals
%     \begin{numerical}
%       \item[tolerance={4e-4}] 2.667
%     \end{numerical}.
%     Thanks, Isaac!
%   \end{cloze}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=lines]{latex}{minted.doc.out}
%
% Note that, when used as a subquestion within a \env{cloze} question,
% the question environments are \emph{not} followed by a question
% name in braces.
% \begin{description}
% \ItemDescribeEnv[cloze]{multi}\oarg{subquestion options} defines a
%             Multiple Choice question inside a Cloze question,
% \ItemDescribeEnv[cloze]{numerical}\oarg{subquestion options} defines a
%             Numerical question inside a Cloze question, and
% \ItemDescribeEnv[cloze]{shortanswer}\oarg{subquestion options} defines a
%             Shortanswer question inside a Cloze question,
% \end{description}
%
% \DescribeKey[cloze]{points}\DescribeDefault{1}
% \DescribeKey[cloze]{default grade}
% Inside \env{cloze} environments, the \optn{points} or \optn{default grade}
% keys can be used to weight the worth of each subquestion. A specific
% constraint applies: the values should be positive integers.
%
% \DescribeKey[cloze]{fraction}
% Inside \env{cloze} environments, the \optn{fraction} key can be used to give
% partial credit or sanction for certain answers. The values
% specified must be integers and are independent of the admissible
% values listed in Table~\vref{tab:fraction}.
%
% \DescribeBoolean[cloze]{single}\DescribeDefault{true}
% \DescribeKey[cloze]{multiple}
% Prior to \Moodle\ version 3.5, within a \env{cloze} question, a multiple choice question
% was necessarily of type \optn{single}, i.e. with a single good answer. If you intend
% to export your quiz to \Moodle\ 3.5+, the option \optn{multiple} can be used for
% questions where students must be able to select several answers.
% The modalities described in Section~\vref{subsec:multi} for setting the
% weight of answers apply. The only difference occurs in \emph{advanced mode}:
% the sum of positive fractions may not be 100\%. In this case, after
% importing the \XML\ file, \Moodle\ will automatically scale the positive
% fractions for a total of 100\% and leave intact the negative fractions.
% ^^A\footnote{\url{https://tracker.moodle.org/browse/MDL-3782?focusedCommentId=421564\#comment-421564}}.
%
% ^^A\DescribeKey[cloze]{vertical}\DescribeKey[cloze]{horizontal}\DescribeKey[cloze]{inline}
% ^^A\DescribeDefault{inline}
% Within a \env{cloze} question, a multiple choice question may be displayed in three
% different modes:
% \begin{description}
% \ItemDescribeKey[cloze]{inline} The inline dropdown box is the default choice
% when only one answer is to be selected (option \optn{single}). The dropdown box
% is visually compact, but also prevents the use of mathematical or \HTML\ formatting.
% This option is incompatible\watchout\ with \optn{multiple} or \optn{single=false}
% (dropdown boxes don't let you pick up several answers!).
% \ItemDescribeKey[cloze]{vertical} displays the subquestion as a vertical column
% of radio buttons instead. This is the default when several items can
% be selected (options \optn{multiple} or \optn{single=false}).
% \ItemDescribeKey[cloze]{horizontal} creates a horizontal row of radio buttons.
% This option works well when the possible answers are short. The result is more
% compact than what \optn{vertical} gives.
% \end{description}
%
% \DescribeBoolean[cloze]{shuffle}
% Starting from \Moodle\ version 3.0, within a \env{cloze} question, the items of a
% multiple choice question can be shuffled. Setting \optn{shuffle=false} will
% guarantee that the answer appear in the order they were typed; the
% default is \optn{shuffle=true}.
%
% \DescribeBoolean[cloze]{case sensitive}\DescribeDefault{false}
% \DescribeBoolean[cloze]{usecase}
% Within a \env{cloze} question, the \env{shortanswer} question can be made case sensitive.
% This option, disabled by default, is selected with \optn{case sensitive} or \optn{usecase}.
%
%\subsubsection{\href{https://docs.moodle.org/en/Description_question_type}{Description}}
%
% \DescribeEnv[quiz]{description}\oarg{question options}\marg{question name}
% is an environment that defines a so-called \emph{Description} question.
%
% The \Moodle\ description type is not really a question. It is more like a label.
% One can set a \optn{feedback} that the student gets when reviewing the submission.
% Tags can be set as well.
%
% For descriptions, \pkg{moodle} redefines \LaTeX's \env{description} environment.
% The scope of this redefinition is limited to the \env{quiz} environment.
%
% The syntax for a Description question is as follows:
% \begin{quote}
%   |\begin{description}|\oarg{question options}\marg{question name} \\
%   \rule{2em}{0pt}\meta{question text} \\
%   |\end{description}|
% \end{quote}
%
% \subsection{Summary of the Key Options}

% \subsection{Automated Generation of Questions}
% 
% \Moodle's \href{https://docs.moodle.org/en/Calculated_question_type}
% {Calculated Questions} types are not supported by this package.
%
% However, much more flexibly, a scripting language can be used in
% combination with \pkg{moodle} to generate a large set of questions,
% based on a prototype.
% 
% In this case, the teacher building a quiz often wants one of the questions
% to be randomly picked up and presented to the student. To achieve this,
% we suggest to apply a specific tag to the questions sharing the same prototype.
% After import in \Moodle, when creating a quiz, this tag can be selected to
% narrow down a random selection of questions.
%
% This way, the feature of calculated questions can be reproduced, while 
% benefiting from the flexibility given by your favorite scripting language.
%
% In this Section, two possible approaches are presented.
% 
% \subsubsection{Script Generating \TeX\ Code}
%
% Here are two examples inspired from the work of
% \href{https://github.com/avohns/python-latex-moodle-quiz}{A. Vohns}.
% The first one relies on the
% native \prog{Lua} capabilities of \LuaLaTeX.
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{quiz}[tags={calculated}]{Example Quiz}
%   \directlua{
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=topline]{latex}{minted.doc.out}
% \vspace{-.7cm}
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   function clozenum_print(pair,op,result)
%     tex.print("\\begin{numerical}$"..pair[1].." "..op.." "..pair[2].."
%     =$".."\\item ",result,"\\end{numerical}")
%   end
%   function cloze_print(pair,points)
%     tex.print("\\begin{cloze}[points="..points.."]{Arithmetic Quiz
%     ("..pair[1]..", "..pair[2]..")}Solve the following tasks!\\\\")
%     clozenum_print(pair,"+",pair[1]+pair[2])
%     clozenum_print(pair,"-",pair[1]-pair[2])
%     clozenum_print(pair,"*",pair[1]*pair[2])
%     if pair[1]/pair[2]==math.floor(pair[1]/pair[2]) then
%       clozenum_print(pair,":",math.floor(pair[1]/pair[2]))
%     end
%     tex.print("\\end{cloze}")
%   end
%   for x = 2,4 do
%     for y = 2,4 do
%       if x>y then
%         if x/y==math.floor(x/y) then points=1 else points=2 end
%         cloze_print({x,y},points)
%       end
%     end
%   end
% \end{VerbatimOut}
% \inputminted[]{lua}{minted.doc.out}
% \vspace{-.7cm}
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   }
%   \end{quiz}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=bottomline]{latex}{minted.doc.out}
% The second example makes use of the \pkg{python} package (|\usepackage{python}|).
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \begin{quiz}[tags={calculated}]{Example Quiz}
%   \begin{python}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=topline]{latex}{minted.doc.out}
% \vspace{-.7cm}
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   def clozenum_print(pair,op,result):
%     print(rf"""\begin{{numerical}}
%   ${pair[0]} {op} {pair[1]} =$\item {result}
%   \end{{numerical}}""")
%   def cloze_print(pair,points):
%     print(rf"""\begin{{cloze}}[points={points}]{{Arithmetic Quiz
%     {(pair[0],pair[1])}}}Solve the following tasks!\\""")
%     clozenum_print([x,y],"+",x+y)
%     clozenum_print([x,y],"-",x-y)
%     clozenum_print([x,y],"*",x*y)
%     if pair[0]/pair[1] == pair[0]//pair[1]:
%       clozenum_print([x,y],":",x//y)
%     print("\end{cloze}")
%   for x in range(2,5):
%     for y in range(2,5):
%       if x > y:
%         if x/y == x//y:
%           points=1
%         else:
%           points=2
%         cloze_print([x,y],points)
% \end{VerbatimOut}
% \inputminted[]{python}{minted.doc.out}
% \vspace{-.7cm}
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
%   \end{python}
%   \end{quiz}
% \end{VerbatimOut}
% \inputminted[gobble=2,frame=bottomline]{latex}{minted.doc.out}
% These two example codes yield the same \XML\ content.
%
% \subsubsection{\TeX\ Code As a Template}
%
% Instead of mixing \TeX\ and scripting code into the same file, it is probably
% a better practice to write a |.tex| template file with predefined variables and
% manipulate the latter using an external script.
%
% The \pkg{moodle} package facilitates the development of question templates.
% Specific control sequences (e.g.~\TeX\ commands) can be used in place of answers
% or other parameters to the questions. In \optn{draft} mode, this should be
% possible even where \pkg{moodle} expects numerical values (e.g.~answers of
% numerical questions).
% After drafting and question development, the control sequences can then be
% substituted, by means of a scripting language, with instances of the variables
% pulled from a database (e.g. |*.csv| file).
% This way, complex quizzes, with parameterized TikZ pictures for instance, can be produced.
%
% This approach, briefly presented in the rest of this section, is demonstrated by
% C. Caprani in \href{https://github.com/ccaprani/genquiz}{genquiz},
% with Python for scripting and Jinja as a templating engine.
%
% The specific control sequence of the template is the \TeX\ command |\VAR|, taking 
% the variable name to be substituted from the database as an argument. In order to
% highlight the fields for template development, in \optn{draft} mode, this command is
% defined to typeset the variable name in bold red font. When generating the \XML\
% question bank, in \optn{final} mode, the variable values are substituted for the
% specific control sequence. Variables can be used to define numerical answers,
% tolerances, and even parameterize TikZ pictures.
% 
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
% \documentclass{article}
% \usepackage[draft]{moodle}
% \usepackage{tikz}
% \newcommand*{\VAR}[1]{\textcolor{red}{\textbf{#1}}}
% \begin{document}
%   \begin{quiz}{Disk or Square}		
%     \begin{cloze}[tags={disk area}]
%                  {Area of the Disk QID00\VAR{qidx}} 
%       \begin{tikzpicture}					
%         \draw[fill=black!20] circle[radius=1];
%         \draw[<->] (0,0)--(1,0)node[above,midway]{\VAR{radius}};				
%       \end{tikzpicture}
%       A disk has radius \VAR{radius}, what is its area?
%       \begin{numerical}[points=1,penalty=0]
%         \item[tolerance = \VAR{areatol}] \VAR{area}
%         \item[fraction=0,feedback={Note the units.}] * % incorrect
%       \end{numerical}		
%       Provide your answers to 3 significant digits.
%     \end{cloze}
%   \end{quiz}
% \end{document}
% \end{VerbatimOut}
% \inputminted[gobble=1,frame=lines]{latex}{minted.doc.out}
%
% A small python code that reads the template and renders the actual |*.tex| file
% is shown below. In this example, the template file is called |quiz_template.tex| and  
% the variables are hard-coded as a list of Python dictionaries. But nothing prevents
% you from generating them on-the-fly or picking them from a database.
% It is worth noting that \prog{jinja2} will process all |\VAR{|\meta{name}|}| occurrences,
% regardless of \TeX\ comments.
%
% \begin{VerbatimOut}[gobble=1]{minted.doc.out}
% import os
% import jinja2
%
% # Tell jinja what to look for in the template
% # (from web.archive.org/web/20121024021221/http://e6h.de/post/11/)
% latex_jinja_env = jinja2.Environment(
%     variable_start_string=r"\VAR{",
%     variable_end_string=r"}",
%     comment_start_string=r"\#{",
%     comment_end_string="}",
%     loader=jinja2.FileSystemLoader(os.path.abspath(".")),
% )
%
% # Load the template
% template = latex_jinja_env.get_template("quiz_template.tex")
%
% # Prepare the variables or read from a database
% database = [
%     {"qidx": 1, "radius": 2, "areatol": 0.1, "area": 12.57},
%     {"qidx": 2, "radius": 3, "areatol": 0.2, "area": 28.27},
%     {"qidx": 3, "radius": 4, "areatol": 0.4, "area": 50.26},
% ]
%
% for row in database:
%     # combine template and variables
%     document = template.render(**row)
%
%     # XML files are generated by moodle.sty in "final" mode
%     document = document.replace(r"\usepackage[draft]{moodle}",
%                                 r"\usepackage{moodle}")
%
%     # write document
%     with open(f"{row['qidx']}.tex","w",encoding="utf-8") as outfile:
%         outfile.write(document)
% \end{VerbatimOut}
% \inputminted[gobble=1,frame=lines]{python}{minted.doc.out}
%
% Executing this Python code will result in three new |.tex| files in the current directory.
% These can then be compiled with a \TeX\ engine to produce the individual \XML\ files.
% Of course, for a large number of quizzes it is preferable to automate this compilation,
% and to combine the large number of resulting \XML\ files into a single \XML\ file for upload
% to Moodle. See \href{https://github.com/ccaprani/genquiz}{genquiz} for more details.
%
% Naturally, the concept of templating, demonstrated here with Python, may be orchestrated
% using other scripting languages.
%
% \section{Conversion to HTML}
%
% \subsection{Level of Support}
%
% The package \pkg{moodle.sty} tries to automatically
% convert the \LaTeX\ code included in the questions
% into \HTML\ for web display.
%
% With this aim, a number of \TeX\ and \LaTeX\ macros,
% commands, and environments undergo a tailored treatment
% when \pkg{moodle} generates the \XML\ file. A few tables
% describe the current level of support:
% \begin{enumerate}
% \item text mode diacritic macros (e.g.~|\"u|) in Table~\vref{tab:diacritics},
% \item text mode macros for ligatures (e.g.~\cmd{\oe}) and other glyphs (e.g.~\cmd{\aa}) in
%       Table~\vref{tab:ligatures_and_glyphs},
% \item horizontal spacing (e.g.~\cmd{\quad}) and line breaking (e.g.~\cmd{\\}) macros in
%       Table~\vref{tab:spacing},
% \item text mode symbols (e.g.~\cmd{\$}) and punctuation (e.g.~\cmd{\textexclamdown}) macros in
%       Table~\vref{tab:symbols_and_punctuation}, and finally
% \item other \LaTeX\ commands (e.g.~\cmd{\emph}) and environments (e.g.~\env{center})
%       in Table~\vref{tab:commands_and_environments}.

% 
% A doubled dash will be converted to en-dash |&ndash;| \emph{outside math mode}.
% Empty groups |{}| will be passed to the XML only \emph{in math mode}.
%
% Be aware that, apart what is described previously, \pkg{moodle} \emph{does
% not know how to convert any other \TeX\ or \LaTeX\ commands to \HTML.}
% If other sequences are used, they may be passed verbatim to the \XML\ file
% or may cause unpredicted results.
%
% If you think of another \LaTeX\ command that should be changed to an HTML
% equivalent, please have a look at Section~\vref{sec:dev}.
%
% \DescribeMacro[question,answer,feedback]{\htmlonly}\oarg{Content for traditional output}
% \marg{HTML content} is a command to be used inside question environments (text,
% answers, or feedback). It lets you pass directly code to the \XML\ file while being
% ignored for the traditional output (\PDF). The \HTML\ content passed as an argument
% is subject to no particular processing and users should not expect to be able to
% pass dangerous characters like |\|, |%|, or |#|. An optional argument allows to
% pass contents to be processed for the traditional output. This argument is
% ignored for the \XML\ output.
% For instance, one can write code like this in a question environment
% \begin{quote}
%   |\htmlonly[\fbox{PDF contents}]{|\\
%   |<div style="border: 1px solid; display: inline-block;">|\\
%   \rule{10em}{0pt}|HTML contents</div>|\\
%   |}|
% \end{quote}
%
% \DescribeMacro[moodle]{\htmlregister}\marg{command} is a command that lets you
% specify a macro that must be expanded in the \XML\ file. It works only when
% the macro is defined without optional argument.\watchout
%
% \DescribeMacro[moodle]{\moodleregisternewcommands}
% When the list of user-defined macros is long, it becomes cumbersome to
% record them individually for expansion. Calling \cmd{\moodleregisternewcommands}
% watches for subsequent calls to \cmd{\newcommand}, \cmd{\renewcommand},
% \cmd{\providecommand}, and their starred variants such that the corresponding
% commands are automatically expanded by \pkg{moodle}.
% Again, this works only if the macros are defined \emph{without} optional
% argument.\watchout
%
% \subsection{Graphics}
% The \pkg{moodle} package can handle two kinds of graphics seamlessly.
% External graphics files may be included with the \cmd{\includegraphics} command
% from the \pkg{graphicx} package, and graphics may be generated internally using \TikZ.
% In either case, the graphics will be embedded in base-64 encoding directly within
% the \Moodle\ \XML\ produced.  This prevents the hassle of managing separate
% graphics files on the \Moodle\ server, as \Moodle\ will store the picture
% within the question in the question bank.
%
% \subsubsection{Default \texttt{includegraphics}}
%
% \DescribeMacro[graphics,graphicx]{\includegraphics}\oarg{options}\marg{file} can be used to
% include graphic files in both \PDF\ and the \XML\ outputs.
% The only options currently supported are \optn{height}\DescribeKey[includegraphics]{height}\
% and \optn{width}\DescribeKey[includegraphics]{width}.  Attempts to use other
% \cmd{\includegraphics} options, such as \optn{scale} or \optn{angle}, will affect the \PDF\
% but not the \XML\ output.
% The dimensions set by \optn{height} and \optn{width} are \TeX\ dimensions such as
% \texttt{4\,in} or \texttt{2.3\,cm}.
% In order to prepare the image for web viewing, this package converts those
% dimensions to pixels using a default of
% 103 pixels per inch.\footnote{This
%   number was selected because an image with
%   |<IMG HEIGHT=103 WIDTH=103 SRC="...">| showed up as almost exactly 1 inch
%   tall and 1 inch wide on several of this author's devices and browsers
%   as of January 2016.}
% \DescribeKey[includegraphics]{ppi}
% That value may be changed by setting the \optn{ppi} key (e.g., \texttt{ppi=72});
% this is probably best done for the entire document with a \cmd{\moodleset} command,
% rather than image-by-image.
%
% \DescribeMacro[graphics,graphicx]{\graphicspath}|{{|\meta{path1}|},{|\meta{path2}|},...}| can be
% used to specify the locations of the pictures to be included.
%
% A special rule was added for the inclusion of \GIF\ pictures (\filenm{.gif} extension).
% These files are passed as-is to the \XML, preserving potential animations.
% However, as pdf\TeX\ engines do not support the \GIF\ format, the picture is
% passed to the \PDF\ output after a conversion to the \PNG\ format. When the \GIF\
% file is animated, only its first frame is passed to the \PDF.
%
%^^A \DescribeMacro[moodle]{\DeclareGraphicsAlien} Users may declare other graphic
%^^A formats with the command \cmd{\DeclareGraphicsAlien}\marg{alien extension}
%^^A \marg{native extension}\marg{command line for conversion}.
%
% \subsubsection{\TikZ\ Pictures}
% \TikZ\ is a user-friendly syntax layer for \acro{PGF}, the macro \LaTeX\ package for creating
% graphics. More information on \TikZ\ can be found at \url{https://ctan.org/pkg/pgf}.
%
% When \TikZ\ is loaded and used to define pictures, \pkg{moodle} invokes
% the \pkg{external} \TikZ\ library, so that each \env{tikzpicture} environment is compiled
% to a freestanding \PDF\ file.
%
% \subsubsection{Package Option \optn{tikz}}\label{subsec:tikz}
% \DescribeOption[moodle]{tikz}
% The \pkg{moodle} package admits a \optn{tikz} option which has the following effects:
% \begin{itemize}
% \item the package \pkg{tikz} is loaded.
% \item \DescribeMacro[tikz]{\includegraphics}\cmd{\includegraphics} embeds graphics in a \TikZ\ picture. Consequences are that
%   \begin{itemize}
%     \item the pictures encoded in the \XML\ file are resampled. This prevents encoding
%           images at a higher resolution than rendered by \Moodle.
%     \item the full set of \cmd{\includegraphics} options is accessible,
% e.g.~\optn{scale=.5}, \optn{angle=90}, or |width=.2\textwidth|.
%   \end{itemize}
% \item \DescribeMacro[tikz]{\embedaspict} a macro \cmd{\embedaspict}\marg{\LaTeX\ contents}
% is provided for the conversion of inline \LaTeX\ material as images. This can serve
% as a workaround to overcome limitations of this package---like the conversion of
% \emph{tabular}s to HTML--- or limitations of \Moodle\ itself.
% For the definition of this macro, the package \pkg{varwidth} is loaded.
% \item optimizations of the \TikZ-external library are disabled: compilation might get
% sensibly slower.
% \end{itemize}
%

% \subsubsection{External Tools}
% The mechanisms used for handling graphics are somewhat fragile and rely upon
% three free external programs.
% \begin{enumerate}
%   \item \prog{GhostScript} (\url{www.ghostscript.com}) is used to convert the \PDF\ output
%         from \TikZ\ into a \PNG\ raster graphics file.
%         The default command line is presumed to be \prog{gswin64c.exe}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%         (if |\ifwindows| from the \pkg{ifplatform} package returns true)
%         or \prog{gs} (if |\ifwindows| returns false).
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%         If your system requires a different command line to invoke \prog{Ghostscript},
%         \DescribeMacro[moodle]{\ghostscriptcommand}
%         you may change it by invoking:
%            \begin{quote}
%             |\ghostscriptcommand|\marg{executable filename}
%            \end{quote}
%   \item When external graphics files such as \PDF\ are included,
%         the \prog{ImageMagick} software (\url{www.imagemagick.org})
%         converts each file to \PNG\ format.
%         The command line for \prog{ImageMagick} is the nondescript word \progcode{convert},
%         \DescribeMacro[moodle]{\imagemagickcommand}
%         but may be changed by invoking \cmd{\imagemagickcommand}\marg{executable filename}.
%   \item \prog{OptiPNG} (\url{http://optipng.sourceforge.net/}) is used to optimize the \PNG\ images.
%         The command line is presumed to be \prog{optipng}, but can be changed with
%         \DescribeMacro[moodle]{\optipngcommand}\cmd{\optipngcommand}\marg{executable filename}.
% \end{enumerate}

%
% Please note the following vital points to make the graphics handling work:
% \begin{itemize}
%   \item As of now, graphics are only supported when compiling directly to a \PDF\
%         with (\prog{pdf}$\mid$\prog{xe}$\mid$\prog{lua})\prog{latex}. Including \acro{PS} graphics or using \TikZ\ with the \DVI$\to$\acro{PS} workflow is not
%         yet supported.
%^^A   \item Filenames should not contains spaces or, under windows, special characters like |_| or |\|.
%   \item You must have \prog{Ghostscript} and \prog{ImageMagick} installed on your system
%         to fully use the graphics-handling capabilities of \pkg{moodle}.
%   \item If \prog{OptiPNG} is not installed, the corresponding system calls will fail with otherwise no
%         impact on the compilation process: \PNG\ files are passed unoptimized to the \XML\ output.
%   \item \LaTeX\ must be able to call system commands; that is, \cmd{\write18} must be enabled.
%         For Mik\TeX, this means adding \progcode{--enable-write18} to the command line of
%         (\prog{pdf}$\mid$\prog{xe}$\mid$\prog{lua})\prog{latex}; for \TeX\ Live, this means adding \progcode{--shell-escape=true}.
%   \item Due to security issues with old versions of \prog{Ghostcript}, some systems default to a
%         policy that prevents the conversion of \PDF\ and \acro{PS} to \PNG. Assuming that, as a user of
%         \pkg{moodle} which requires shell escape capabilities, you either use a sandboxed
%         environment or trust the files handled at the system-level, you may want to disable this
%         over-zealous security policy. For example,
%         \href{https://stackoverflow.com/a/52661288/14608059}{see this}.
%   \item Users of the \pkg{circuitikz} package (\url{https://www.ctan.org/pkg/circuitikz}) must
%         enclose their circuits' \TikZ\ code in the |tikzpicture| environment instead of
%         the historical \env{circuitikz} environment. That is required, as of \TikZ\ 2.1,
%         by the \pkg{external} library.
% \end{itemize}
%
% \subsubsection{Package Option \optn{svg}}\label{subsec:svg}
%
% \paragraph{Important Notice}\watchout[experimental] \emph{The \optn{svg} option is
% an experimental feature introduced in \pkg{moodle} v0.8. It has been tested only
% under Linux and Windows, with TeX Live 2020, Inkscape v1.0.1 and Scour 0.38.2.}
%
% \DescribeOption[moodle]{svg} The \pkg{moodle} package admits an experimental
% \optn{svg} option which has the following effects:
% \begin{itemize}
% \item \DescribeMacro[svg]{\includegraphics}\cmd{\includegraphics} can be used to import
% \SVG\ graphic files directly (extension \filenm{.svg} or \filenm{.SVG}). In this case, the \SVG\ file
% is passed as-is to the \XML\ output and is converted using \href{https://inkscape.org/}
% {\prog{Inkscape}} (must be installed) for inclusion in the \PDF\ output.
% \item the graphic files in \PDF\ format are converted to the \SVG\ format using
% \href{https://inkscape.org/}{Inkscape} (must be installed), rather than being
% rasterized. Before inclusion to the \XML\ output, the \SVG\ file is optimized using
% the \href{https://github.com/scour-project/scour}{Scour} utility. This
% optimization step is optional in the sense that, if the Scour call fails,
% the un-optimized \SVG\ file will be passed to the \XML\ output.
% Two processes benefit from this \PDF$\to$\SVG\ conversion:
%   \begin{itemize}
%     \item inclusion of \PDF\ graphics with \cmd{\includegraphics}, and
%     \item \TikZ\ pictures that are externalized.
%   \end{itemize}
% \end{itemize}
%
%
% The call of external \SVG\ manipulation utilities can be modified using the macros:
% \begin{description}
%   \item \ItemDescribeMacro[svg]{\PDFtoSVGcommand}\ for conversion
%         from \PDF\ to \SVG,
%   \item \ItemDescribeMacro[svg]{\SVGtoPDFcommand}\ for conversion
%         from \SVG\ to \PDF, and
%   \item \ItemDescribeMacro[svg]{\optiSVGcommand}\ for the
%         optimization of \SVG\ files.
% \end{description}
%
% \subsection{Verbatim Code}
%
% Because, for \HTML\ translation, \pkg{moodle} parses the body of questions, the use of
% verbatim code results in compilation errors. This is why the use of |\verb|,
% \env{verbatim} and other standard utilities is not supported.
%
% However, using the following three utilities, verbatim code can be imported from an external file:
% \begin{enumerate}
%   \item \cmd{\verbatiminput}\marg{filename}\DescribeMacro[verbatim]{\verbatiminput}\
%         from the \pkg{verbatim} package inserts verbatim code in both the \PDF\ and the
%         \acro{XML} for \Moodle, without fancy additions.
%   \item The macro \cmd{\VerbatimInput}\marg{options}\marg{filename}
%         \DescribeMacro[fancyvrb,fvextra]{\VerbatimInput}\ from
%         \pkg{fancyvrb} or \pkg{fvextra} does more, with several options and settings
%         offered (see below).
%         The variants \DescribeMacro[fancyvrb,fvextra]{\BVerbatimInput}\cmd{\VBerbatimInput} and
%         \DescribeMacro[fancyvrb,fvextra]{\LVerbatimInput}\cmd{\LVerbatimInput} are also supported,
%         with no difference on the \XML\ output.
%         The variants with a star are unsupported and result in errors when used.
%   \item On top of that \cmd{\inputminted}\oarg{options}\marg{lang}\marg{filename}\
%         \DescribeMacro[minted]{\inputminted} from the \pkg{minted} package offers syntax
%         highlighting tailored to the specified language.
% \end{enumerate}
% The \pkg{moodle} package handles these three commands to pass the code in the output \XML.
% With \cmd{\inputminted}, an external Python tool, \prog{pygmentize}, performs syntax analysis and
% its \HTML\ formatter is used to populate the \XML. With the other commands, the contents of the
% file is passed almost as-is to the XML: in order to survive \Moodle\ import and \HTML\ rendering,
% characters |<|, |>|, |&|, |'|, and |"| are converted to \HTML\ equivalents.
%
% With \cmd{\VerbatimInput} and \cmd{\inputminted}, the options that are taken care of for XML
% generation are listed in Table~\vref{tab:verbatim-options}.
% Using \cmd{\fvset}\marg{key=value,\dots}, options can be set globally. Equivalently, with \pkg{minted},
% \cmd{\setminted}\oarg{lang}\marg{key=value,\dots} is available.

% When code decorated with left-side line numbers is placed in question items, the output \PDF\ could
% show a collision between numbers of the item and the first line. To avoid this, \cmd{\LVerbatimInput} or
% \cmd{\BVerbatimInput} can be used. Instead, when \pkg{minted} is used, the ``left-right'' mode can be
% enforced with the \LaTeX\ command:
% \begin{quote}
%   |\RecustomVerbatimEnvironment{Verbatim}{LVerbatim}{}|
%  \end{quote}
%
% When using utilities from \pkg{fancyvrb}, \pkg{fvextra}, or \pkg{minted}, \pkg{moodle}
% sets framing options for the display of code in the output \PDF:
% \begin{quote}
%   |\fvset{frame=lines,label={[Beginning of code]End of code},|\\
%   |       framesep=3mm,numbersep=9pt}|

% These settings can be overridden using \cmd{\fvset} after the preamble.
%
% \section{Internationalization}
%
% This section is intended for authors of \Moodle\ quizzes writing in one or several
% languages other than English. It seems reasonable to assume that those users have heard
% of the packages \pkg{babel} or \pkg{polyglossia} (\XeTeX\ or \LuaTeX\ only), that
% both aim at enforcing language-related rules to \LaTeX\ documents.
%
% The contents of the \XML\ file that is generated by \pkg{moodle} depends entirely
% on the user input and \Moodle's \XML\ syntax: there is little room for \pkg{moodle} to
% internationalize something here. Instead, the focus of this section  is the \PDF\
% typesetting that is determined by \pkg{moodle}, where some internalization
% efforts can be of help.
%
% Both \pkg{babel} and \pkg{polyglossia} provide ways of specifiying a language for
% the document or a part of it. If one of these packages is loaded in the preamble,
% \pkg{moodle} will automatically load the package \pkg{translator} and rely on it
% to provide translations of its keys (see Table~\vref{tab:language_keys}) in
% different languages, with some knowledge on aliases. The package
% \pkg{translations} does a very similar job and can be loaded in the preamble
% to serve, if desired, as a replacement for \pkg{translator}.
%
% Currently, full-support is provided for English, French, German, Italian, and
% Spanish. Very limited support is provided for Catalan, Croatian, Czech, Danish, Dutch,
% Estonian, Finnish, Hungarian, Icelandic, Lithuanian, Norsk, Polish, Portuguese,
% Romanian, Swedish, and Turkish.
%
% Users may define their own translations in the preamble. For instance
% \begin{quote}
%   |\AfterEndPreamble{|\\
%     |  \DeclareTranslation|\marg{babel language name}|{True}{Foo}%|\\
%     |  \DeclareTranslation|\marg{babel language name}|{False}{Bar}%|\\
%   |}|
% \end{quote}
% Note that, when the package \pkg{translations} is loaded,
% \cmd{\AfterEndPreamble} must not be used.
%
% Contributions to improve or broaden the linguistic support are very welcome.

% \section{Package Development}\label{sec:dev}
%
% \subsection{Feature Requests, Bug Reports, and Contributions}
%
% This package is developed as a collaborative project, currently hosted
% on the Gitlab server instance \url{https://framagit.org/mattgk/moodle}.
% The project's activity can be monitored there: reported issues, last
% modifications, \dots
%
% Contributions, either bug reports or fixes, are welcome. Users willing to
% help can either sign-in with an existing \brand{GitHub}, \brand{Gitlab.com}, or
% \brand{Bitbucket} account or register a new account.
%
% Of course, getting in touch with the package maintainer by
% \href{mailto:guerquin-kernATcrans.org}{email} works as well.
%
% The authors have used this package together with a limited number of colleagues
% for a few semesters of teaching. If other users adopt this package, we fully expect them
% to find bugs.
%
% When experiencing a problem and before reporting it, please check whether
% or not something similar has already been filed as an issue
% \href{https://framagit.org/mattgk/moodle/-/issues?scope=all&state=all}{here}.
% If the problem appears to be new, please report it by following these steps:
% \begin{enumerate}
% \item Prepare a \emph{minimal} working example, i.e. a \filenm{.tex} file shrunk down
% to the strict minimum (loaded packages, code, \dots) while still showing the
% faulty behavior upon compilation.
% \item Gather and send the \filenm{*.tex}, \filenm{*.log} and \filenm{*-moodle.xml} files together
% with an explanation about
%   \begin{itemize}
%     \item your local working environment (\TeX\ engine and distribution, platform,
%           external tools used, \dots),
%     \item the version of the \Moodle\ instance you are using
%           (for instance see the file |https://|\meta{server-domain}|/lib/upgrade.txt| )
%     \item the faulty behavior, and
%     \item what you expected instead.
%   \end{itemize}
% \end{enumerate}
%
% \subsection{Known Limitations}
%
% When using with pdf\TeX\ for compilation, \pkg{moodle} supports
% question contents with \acro{ASCII} characters only. The use of
% non-\acro{ASCII} characters may work in some cases but will most
% probably yield compilation errors or undesired \XML\ contents.
%
% Instead, \pkg{moodle} will work flawlessly when \XeTeX\ and
% \LuaTeX\ are used to compile \UTF-8 encoded documents.
%
% Table~\vref{tab:support-limitations} lists
% some features supported, limitations, and bugs.

%\begin{tablenotes}
%\item[1] \Moodle\ prompts the student for an answer and then compares it to the
%solutions provided. This is text-only.
%\item[2] \Moodle\ uses a dropdown list to let one choose among the possible
%answers. This forbids either picture inclusion and \LaTeX\ rendering.
%\item[3] Not supported by \Moodle\ (in this context, answer-specific feedback
%represents lots of possible combinations).
%\item[4] The drag-and-drop-matching plugin seems broken before version 1.6
%20190409. \Moodle's \XML\ import fails with a \texttt{dmlwriteexception} when
%the field content exceeds few hundreds characters. This prevents the inclusion
%of most base64 images and maybe some complicated equations.
%\item[5] For this question type and in the context of \XML\ generation, the
%Answer column represents the ``template" while the Feedback column represents
%the ``notes for the grader". Obviously, the grading process is not automatic
%and there is no answer-specific feedback.
%\item[6] Picture and \LaTeX\ rendering could be done, but only after
%submission and only if the keyval ``response format" is set to ``html".
%\item[7] \Moodle\ only reveals the feedback when hovering the checkmark or X
%mark with the mouse.
%\end{tablenotes}
%\end{threeparttable}
%\end{table}
%
% Some features of \Moodle\ quizzes have not yet been implemented in \pkg{moodle}.
% Here is a non-exhaustive list.
% \begin{itemize}
%   \item \Moodle's feature of designating feedback for correct,
%         partially correct, and incorrect answers.
%^^A   \item Calculated questions; that is, automatically generated \env{numerical} questions
%^^A         using randomly chosen numbers.
%   \item Hints
%   \item Units handling in \env{numerical} questions
% \end{itemize}
%
% \subsection{Compatibility}
% This package has been originally written for and tested with the implementation of
% \Moodle\ 2.9 run by Moodlerooms for St.~Norbert College in January 2016.
% Since then, it has been successfully combined with \Moodle\ 3.5.
%
% The package option \optn{LMS} lets you specify the targeted \Moodle\ version
% and helps ensuring compatibility.
%
% As the ultimate purpose of this package is the generation of \XML\ files,
% future versions of \pkg{moodle} will attempt to maintain backwards
% compatibility with earlier versions regarding the \XML\ output, apart from
% bug fixes.
% Backwards compatibility of the \PDF\ output is not yet guaranteed, however,
% in case the author or users discover better ways for the \PDF\ to display
% the underlying \XML\ data to be proofread.
%
% In other words, compiling your current \filenm{.tex} file with a future version
% of \pkg{moodle} should produce the same \XML\ file it does now
% (apart from bug fixes),
% but it might produce a more informative, and hence different,
% \PDF\ output.
%
% \subsection{Unrelated Tip: Quality of \Moodle\ \TeX\ Images}
% This has nothing to do with \pkg{moodle}, but is a Frequently Asked Question
% in is own right.
% On some servers, at least, \Moodle's default ``\TeX\ Filter'' for
% displaying mathematical notation is of abysmally poor quality, rending mathematics
% as low-resolution \PNG's.  One solution that has worked for me is to go
% to ``Course Administration $\to$ Filters,'' turn ``\TeX\ Notation'' \emph{off},
% but turn ``MathJax'' \emph{on}.  This forces \TeX\ code to be rendered by MathJax
% instead of \Moodle, producing much higher-quality results.

%             without specifying the extension (courtesy of Colin Caprani).
%       \item In answers of \env{matching} questions, some \TeX\ macros will not
%             break compilation. A problem with curly braces persists.
%       \item The cloze subquestions now inherit \optn{points} set at
%             the higher levels.
%       \item Option \optn{single=false} now works in Cloze \env{multi} questions.

\def\moodleset#1{\setkeys{moodle}{#1}}%
%    \end{macrocode}
% We first define some macros that will help us write other macros.
% Calling |\generate@moodle@write@code|\marg{name}|<|\meta{HTML tag}|>|\marg{text to write}
% creates a macro |\moodle@write|\meta{name}, taking no parameters,
% which writes the code |<|\meta{HTML tag}|>...</|\meta{HTML tag}|>|
% to the output \XML\ file.
%
% The ordinary version |\generate@moodle@write@code| passes its output text |#3|
% through the HTMLizer, producing \HTML\ code, while the starred variant
% |\generate@moodle@write@code*| passes |#3| verbatim as text.
%
% For example,
% |\generate@moodle@write@code{excuse}<EXC>{\theexcuse}|
% would expand to
% \begin{Verbatim}[gobble=4,frame=single]
%   \gdef\moodle@writeexcuse{%
%     \xa\def\xa\test@iii\xa{\theexcuse}%
%     \ifx\test@iii\@moodle@empty

%
%    \begin{macrocode}
%The Answers \XML\ depends heavily on the question type.
%Each type of question defines how it obtains answers from the LaTeX input,
%how it typesets those in a \PDF\ or \DVI, and how it writes them as \XML\ code.
%It will write that \XML\ to the macro \moodle@answers@xml,
%which them gets written to the file when \moodle@writeanswers
%is invoked.

% \subsection{Typesetting options}
% This section provides the tools to allow on to control how the quiz gets typeset

%
% \subsection{Front Ends}
% This section creates the user interface for the various question types.
% First, we define a generic command to create
% a front-end environment for a Moodle question type.
% In order to function, the following macros must be hard-coded:
% \begin{itemize}
%   \item |\moodle@|\meta{type}|@latexprocessing|:
%     Loops through the saved |\item|'s to typeset them in LaTeX,
%     usually inside an itemize or enumerate environment.
%   \item |\save|\meta{type}|answer#1|:
%     Processes the text of a single |\item| to save the information to memory,
%     usually inside |\moodle@answers@xml|.
%   \item |\write|\meta{type}|question|:
%     Writes the information, hitherto saved only in macros,
%     into the \XML\ file.
% \end{itemize}
% For example, to create the `shortanswer' question type,
% we shall call
% \begin{Verbatim}[gobble=5,frame=single]
%    \moodle@makefrontend{shortanswer}
%    \def\moodle@shortanswer@latexprocessing{...}
%    \def\saveshortansweranswer#1{...}

% \subsection{Cloze Questions}
% Because cloze questions are so complicated, they get their own section of code.
% The cloze strategy is as follows.
%
% All subquestions show up as part of the question body text.
% For each type of subquestion, we have a cloze-version environment
% that actually has 2 versions, depending on whether we are doing LaTeX or \XML\ processing.
% So the main environment is quite typical:
% \begin{enumerate}
%   \item Process the body as LaTeX.
%         During this run, a |\begin{multi}| etc.~will be processed for display onscreen.
%   \item Then save the body as the questiontext for \XML.
%         During this run, a |\begin{multi}| etc.~will be parsed and turned into
%         cloze code as part of the \XML\ questiontext.

% \section{Converting \LaTeX\ to HTML}
% A lot of work must now be done to convert the \LaTeX\ code
% of a question or answer into \HTML\ code with embedded \TeX\ for math.
%
% \subsection{Catcode Setup}
% First, we create versions of the special characters with catcode 12, ``other.''
%    \begin{macrocode}
{\catcode`\#=12\gdef\otherhash{#}%
 \catcode`\~=12\gdef\othertilde{~}%
 \catcode`\&=12\gdef\otherampersand{&}%
 \catcode`\^=12\gdef\othercaret{^}%
 \catcode`\$=12\gdef\otherdollar{$}%
 \catcode`\%=12\gdef\otherpercent{%}
 \catcode`\[=12\gdef\otherlbracket{[}
 \catcode`\]=12\gdef\otherrbracket{]}}%
{\catcode`\=\string=12\gdef\otherequal{=}}%
{\catcode`\ =12\gdef\otherspace{ }}%
{\ttfamily\catcode`\|=0\catcode`\\=12\relax|gdef|otherbackslash{\}}%
{\catcode`\[=1\catcode`\]=2\catcode`\{=12\catcode`\}=12%
 \gdef\otherlbrace[{]\gdef\otherrbrace[}]\gdef\clozelbrace[{]\gdef\clozerbrace[}]]%

\edef\@otherlbrace{\otherlbrace}%
\edef\@otherrbrace{\otherrbrace}%
\edef\@otherlbracket{\otherlbracket}%
\edef\@otherrbracket{\otherrbracket}%
\edef\@clozelbrace{\clozelbrace}%
\edef\@clozerbrace{\clozerbrace}%
\edef\@otherdollar{\otherdollar}%
\edef\@otherbackslash{\otherbackslash}%
\edef\@othertilde{\othertilde}%
\edef\@otherequal{\otherequal}%
%    \end{macrocode}
%
% Next, we define commands to change catcodes to a suitable verbatim mode
% for transcription.
%
%    \begin{macrocode}
{ \catcode`\[=1\relax
  \catcode`\]=2\relax
  \catcode`\|=0\relax
  |gdef|verbcatcodesweirdest[
    |catcode`\{=12|relax
    |catcode`\}=12|relax
    |catcode`\\=12|relax

\def\retokenizingcatcodes{%
  %For rescanning previously scanned text, all true comments will already be gone,
  %but % signs may have been inserted by Cloze questions, so we want to treat them as 'other.'
  %
  % TODO: #'s are more worrisome.
  \normalcatcodes
  \catcode`\%=12\relax
}
%    \end{macrocode}
%
% \subsection{Detokenization and Retokenization}
%
% We will be processing a \TeX\ token list.
% Based on its content, sometimes we will want it to be detokenized to
% individual characters, but other times we want it retokenized so that
% \TeX's own parsing mechanism can gather up the parameters of macros.
% We use the e\TeX\ primitive command |\scantokens| to do this.
%
% The following code (catcodes, groupings and all) defines a |\scantokens@to@macro| macro.
% That will assemble and disassemble strings of tokens
% using any changing schemes of catcodes we desire.
%
% We define |^^A| to be |\gdef\stm@saved|, while |^^B| and |^^C| are substitutes for |{| and |}|, respectively.
% This permits us to define |\scantokens@to@macro| in a peculiar catcode regime.
%    \begin{macrocode}
\begingroup
  \catcode`\^^A=13\gdef^^A{\gdef\stm@saved}%
  \catcode`\^^B=1\catcode`\^^C=2\relax
  \long\gdef\scantokens@to@macro#1#2#3{%
    % #1 = control sequence to be defined
    % #2 = command to change catcodes, e.g. \verbcatcodes,
    %      and define any command sequences
    % #3 = text to be retokenized and saved into #1.
    \bgroup
      \def\texttorescan{#3}%
      \catcode`\^^A=13\catcode`\^^B=1\catcode`\^^C=2\relax
      \xa\def\xa\arg\xa{\xa^^A\xa^^B\texttorescan^^C}%
      #2%

% plus one terminal |\@htmlize@stop|.
% We are trying to break up the text into its first group and the remainder.
% This |\@htmlize@stop| is needed in case |#2| has the form ``|{...}|'',
% since we don't want \TeX\ to strip the braces off.
% Thus |\@htmlize@remainder| will definitely end in ``|\@htmlize@stop|''.

%    \begin{macrocode}
\long\def\htmlize@redefine@expansionmacros{}%
%    \end{macrocode}
% If |\mymacro| needs no changes to be suited for expansion,
% you can simply call |\htmlize@record@expand{\mymacro}|
% or |\htmlregister{\mymacro}|
% to record that it should be expanded on its way to the \HTML.
% Examples would be user-built macros such as |\inv|$\to$|^{-1}|
% or |\N|$\to$|\mathbb{N}|.
%    \begin{macrocode}

  \xa\listadd\xa\htmlize@cs@expandlist\xa{\string#1}%
}
\let\htmlregister=\htmlize@record@expand
%    \end{macrocode}
% Often users define a list of macros at the end of the preamble.
% It can be cumbersome to record individually these macros for expansion.
% By calling |\moodleregisternewcommands| they trigger the automatic
% expansion of macros defined subsequently using |\newcommand|,
% |\renewcommand|, |\providecommand| or their starred variants.
%    \begin{macrocode}
\def\moodleregisternewcommands{%
  %% INSPIRED FROM
  %https://tex.stackexchange.com/questions/73271/how-to-redefine-or-patch-the-newcommand-command

    \saved@ifdefinable{##1}{##2}%
    \htmlregister{##1}
  }%
  \let\@@ifdefinable\@ifdefinable
}%
%    \end{macrocode}
% On the other hand, if an alternate version of the macro is
% needed for \HTML\ purposes, you can define its \HTML\ version with
% |\html@def\mymacro...|
% Parameters are okay.
% An example would be
% |\html@def\emph#1{<EM>#1</EM>}|.
%    \begin{macrocode}
\long\def\html@def#1{%
  \htmlize@record@expand{#1}%
  \xa\def\xa\htmlize@scrap\xa{\xa\let\xa#1\csname html@\string#1\endcsname}%
  \xa\g@addto@macro\xa\htmlize@redefine@expansionmacros\xa{\htmlize@scrap}%
  \xa\def\csname html@\string#1\endcsname%

%    \end{macrocode}

% which abuts directly on the remainder of the definition.

% The following code is adapted from the command |\Ginclude@graphics| as
% found in \filenm{graphics.sty}.
% Calling |\moodle@media@find|\marg{filename} looks for the file the
% same way |\includegraphics| does, with or without extension provided,
% in the current folder and in folders specified with |\graphicspath{}|.
% The allowed extensions and their relative priorities can be set
% via |\DeclareGraphicsExtensions{}|.
% The outcome is that the macros |\moodle@media@base| and |\moodle@media@ext|
% are set with the basename, including path, and extension, respectively.
