+% \subsection{The file \tt{cloze.tex}}
+%
+% The cloze package uses following naming conventions: Internal / private
+% macros / commands / envirnoments are written in PascalCase, public
+% ones are written in lowercase. Earlier versions of this package used
+% @ characters for private macros. The lower level / private macros
+% are now defined in the plain Lua\TeX{} version of the package and
+% used to set cloze text in plain Lua\TeX{}.
+%
+% \begin{macrocode}
+\directlua{
+ cloze = require('cloze')

+%
+% \subsubsection{Internal macros}
+%
+% \begin{macro}{\ClozeSetToGlobal}
+% Set the Lua variable |registry.is_global| to |true|. All options
+% are then stored in the variable |registry.global_options|.
+% \begin{macrocode}
+\def\ClozeSetToGlobal{%
+ \directlua{cloze.set_is_global(true)}%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ClozeSetToLocal}
+% First unset the variable |registry.local_options|. Now set the Lua
+% variable |registry.is_global| to |false|. All options are then stored
+% in the variable |registry.local_options|.
+% \begin{macrocode}
+\def\ClozeSetToLocal{%
+ \directlua{
+ cloze.unset_local_options()

+%
+% \begin{macro}{\ClozeColor}
+% Convert a color definiton name to a PDF colorstack string, for example
+% convert the color name |blue| to the colorstack string
+% |0 0 1 rg 0 0 1 RG|. The macro definition |\ClozeColor{blue}|
+% builds itself the macro |\color@blue|, which expands to the PDF
+% colorstack string. The colorstack string is necessary to generate a
+% PDF colorstack whatsit.
+% \begin{macrocode}
+\def\ClozeColor#1{\csname\string\color@#1\endcsname}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ClozeStartMarker}
+% At the begining |\ClozeStartMarker| registers the required Lua
+% callbacks. Then it inserts a whatsit marker which marks the begin of a
+% gap.
+% \begin{macrocode}
+\def\ClozeStartMarker#1{%
+ \strut\directlua{
+ cloze.register('#1')
+ cloze.marker('#1', 'start')

+}
+% \end{macrocode}
+% \end{macro}
+%

+% Load the cloze lua module and put all return values in the variable
+% |cloze|.
+%
+% \begin{macro}{\clozesetoption}
+% \cmd{\clozesetoption} is a wrapper for the Lua function
+% |registry.set_option|. \cmd{\clozesetoption}\marg{key}\marg{value}
+% sets a key \meta{key} to the value \meta{value}. The plain Lua\TeX{}
+% version always sets to the global options. The Lua\LaTeX-version
+% can set values both to the local and the global options store.

+%
+% \begin{macro}{\ClozeSetLocalOptions}
+% This macro is used in all cloze commands to handle the optional

+%
+% \subsubsection{Options}
+%
+% \emph{cloze} offers key-value pairs to use as options. For processing
+% the key-value pairs we use the package
+% \href{https://www.ctan.org/pkg/kvoptions}{kvoptions}.
+% To make all key-value pairs accessibly to Lua code, we use the
+% declaration
+% \cmd{\define@key}\marg{CLZ}\marg{option}\oarg[]\marg{\dots}. This
+% declaration comes from the package
+% \href{https://www.ctan.org/pkg/keyval}{keyval}.
+%
+% At start all values are declared as global options. At the Lua side
+% all values are now stored in the |registry.global_options| table.
+%
+% \begin{macrocode}
+\ClozeSetToGlobal

+%
+% We use the abbreviation |CLZ| for \emph{cloze} as family name and

-\section{Introduction}
-
-\emph{cloze} is a \LaTeX{} package to generate cloze texts. It uses
-the capabilities of the modern \TeX{} engine \emph{Lua\TeX}. Therefore,
-you must use Lua\LaTeX{} to create documents containing gaps.
-
-\begin{verbatim}
-lualatex cloze-text.tex
-\end{verbatim}
-
-The main feature of the package is that the formatting doesn't change
-when using the |hide| and |show| \secref{sec:option-hide} options.
-
-\newcommand{\clozelorem}{%
-Lorem ipsum \cloze{dolor sit} amet, consectetur \cloze{adipisicing}
-elit, sed do eiusmod tempor incididunt ut labore et \cloze{dolore magna}
-aliqua. Ut enim ad minim veniam, quis nostrud \cloze{exercitation}
-ullamco laboris nisi ut \cloze{aliquip} ex ea commodo consequat.%
-}
-
-\begin{example}
-\clozelorem
-\end{example}
-
-\clozeset{hide}
-
-The command |\clozeset{hide}| only shows gaps. When you put both texts
-on top of each other you will see that they perfectly match.
-
-\begin{example}
-\clozelorem
-\end{example}
-
-\clozeset{show}

-
-\section{Usage}
-
-There are the commands
-\cmd{\cloze},
-\cmd{\clozefix},
-\cmd{\clozefil},
-\cmd{\clozenol},
-\cmd{\clozestrike} and the environments
-|clozepar| and
-|clozebox|
-to generate cloze texts.

-\subsection{The commands and environments}
-
-\subsubsection{\cmd{\cloze}}
-\label{sec:command-cloze}
-
-\DescribeMacro{\cloze} \cmd{\cloze}\oarg{options}\marg{some text}: The
-command \cmd{\cloze} is similar to a command that offers the possibility
-to underline the texts. \cmd{\cloze} does not prevent line breaks. The
-width of a gap depends on the number of letters and the font used.
-The only option which affects the widths of a gap is the option
-|margin| \secref{sec:option-margin}.
-
-\begin{example}
-Lorem ipsum \cloze{dolor} sit amet, \cloze{consectetur} adipisicing
-elit, sed do eiusmod tempor incididunt ut labore et dolore
-\cloze{magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation
-ullamco laboris nisi} ut aliquip ex ea commodo consequat.
-\end{example}
-
-\noindent It is possible to convert a complete paragraph into a `gap'.
-But don't forget: There is a special environment for this: \tt{clozepar}
-\secref{sec:command-clozepar}.
-
-\begin{example}
-\cloze{Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
-eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad
-minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip
-ex ea commodo consequat.}
-\end{example}
-
-\noindent The command \cmd{\cloze} doesn't change the behavior of the
-hyphenation. Let's try some long German words:
-
-\begin{example}
-es
-\cloze{Te\-le\-kom\-mu\-ni\-ka\-tions\-ü\-ber\-wach\-ung}
-geht
-\cloze{Un\-ter\-neh\-mens\-steu\-er\-fort\-ent\-wick\-lungs\-ge\-setz}
-\cloze{Ab\-teil\-ungs\-lei\-ter\-in}
-\cloze{Ober\-kom\-mi\-sar\-in}
-auch
-\cloze{Fil\-lial\-lei\-ter\-in}
-kurz
-\cloze{Ober\-kom\-mi\-sar\-in}
-\cloze{Un\-ter\-neh\-mens\-steu\-er\-fort\-ent\-wick\-lungs\-ge\-setz}
-\cloze{Fil\-lial\-lei\-ter\-in}
-\cloze{Metz\-ger\-mei\-ster\-in}
-in
-\cloze{Ab\-teil\-ungs\-lei\-ter\-in}
-der

-\cloze{Hoch\-lei\-stungs\-flüs\-sig\-keits\-chro\-ma\-to\-gra\-phie}

-\subsubsection{\cmd{\clozesetfont}}
-\label{sec:command-clozesetfont}
-\label{sec:command-clozefont}
-
-\DescribeMacro{\clozesetfont}
-The gap font can be changed by using the command
-\cmd{\clozesetfont}. \tt{\string\cloze\-set\-font} redefines the command
-\cmd{\clozefont} which contains the font definition.
-Thus, the command \tt{\string\clozesetfont\string{\string\Large\string}}
-has the same effect as
-\tt{\string\re\-new\-com\-mand\string{\string\cloze\-font\string}%
-\string{\string\Large\string}}.
-
-\clozesetfont{\Large}
-
-\begin{example}
-Excepteur \cloze{sint} occaecat \cloze{cupidatat} non proident.
-\end{example}
-
-\noindent Please do not put any color definitions in
-\cmd{\clozesetfont}, as it won't work. Use the option
-|textcolor| instead \secref{sec:option-textcolor}.
-
-|\clozesetfont{\ttfamily\normalsize}| changes the gap text for example
-into a normal sized typewriter font.
-
-\clozesetfont{\ttfamily\normalsize}
-
-\begin{example}
-Excepteur \cloze{sint} occaecat \cloze{cupidatat} non proident.
-\end{example}
-
-\clozesetfont{\itshape}

-
-\subsubsection{\cmd{\clozefix}}
-\label{sec:command-clozefix}
-
-\DescribeMacro{\clozefix} \cmd{\clozefix}\oarg{options}\marg{some text}:
-The command \cmd{\clozefix} creates gaps with a fixed width. The
-clozes are default concering the width \tt{\getdefaults{width}}.
-
-\begin{example}
-\noindent Lorem ipsum dolor sit amet:
-\begin{compactenum}
-\item \clozefix[width=5cm]{consectetur}
-\item \clozefix[width=5cm]{adipisicing}
-\item \clozefix[width=5cm]{elit}
-\end{compactenum}
-sed do eiusmod.
-\end{example}
-
-Gaps with a fixed width are much harder to solve.
-
-\begin{example}
-Lorem ipsum dolor \clozefix[align=center,width=3cm]{sit} amet,
-\clozefix[align=center,width=3cm]{consectetur} adipisicing elit, sed do
-eiusmod tempor incididunt \clozefix[align=center,width=3cm]{ut} labore
-et dolore magna aliqua.
-\end{example}
-
-Using the option |align| you can make nice tabulars like this:
-
-\begin{example}
-\begin{tabular}{p{5cm}p{4cm}}
-\raggedleft Composer & Life span \\

-\subsection{Special application areas}
-
-This section lists examples that didn’t work in older versions of
-the cloze package and required special treatment to work as expected.
-
-\subsubsection{The math mode}
-
-By default the package uses |\itshape| to format the cloze text. In
-math mode you have to reset the cloze text format by calling
-|\clozesetfont{}|. A known bug ist: You can’t show and hide
-single display math formulas. Only the last |\clozeshow| or |\clozehide|
-takes effect on the whole document. Side note: The usage of the \TeX
-primitive syntax |$$| is not recommended.
-
-\clozesetfont{}
-
-\begin{minted}{latex}
-\clozesetfont{}
-$$1 + 1 = \cloze{2}$$
-\clozesetfont{\itshape}
-\end{minted}
-
-$$1 + 1 = \cloze{2}$$
-
-\noindent
-|\[\]| should be used instead.
-
-\begin{minted}{latex}
-\[123 + 456 = \cloze{579}\]
-\end{minted}
-
-\[123 + 456 = \cloze{579}\]
-
-\begin{minted}{latex}
-\begin{displaymath}
-2^{\cloze{2}} = 4
-\end{displaymath}
-\end{minted}
-
-\begin{displaymath}
-2^{\cloze{2}} = 4
-\end{displaymath}
-
-\noindent
-The inline math mode works too:
-
-\begin{minted}{latex}
-${\sqrt[3]{\cloze{8}}} = 2$ and ${\sqrt[\cloze{3}]{\cloze{8}}} = 2$
-\end{minted}
-
-\begin{center}
-${\sqrt[3]{\cloze{8}}} = 2$ and ${\sqrt[\cloze{3}]{\cloze{8}}} = 2$

-% \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}{\cloze@set@option}
-% \cmd{\cloze@set@option} is a wrapper for the Lua function
-% |registry.set_option|. \cmd{\cloze@set@option}\oarg{key}\marg{value}
-% sets a key \meta{key} to the value \meta{value}.

-% Convert a color definiton name to a PDF colorstack string, for example
-% convert the color name |blue| to the colorstack string
-% |0 0 1 rg 0 0 1 RG|. The macro definition |\cloze@color{blue}|

-% \subsubsection{Options}
-%
-% \emph{cloze} offers key-value pairs to use as options. For processing
-% the key-value pairs we use the package
-% \href{https://www.ctan.org/pkg/kvoptions}{kvoptions}.
-% To make all key-value pairs accessibly to Lua code, we use the
-% declaration
-% \cmd{\define@key}\marg{CLZ}\marg{option}\oarg[]\marg{\dots}. This
-% declaration comes from the package
-% \href{https://www.ctan.org/pkg/keyval}{keyval}.
-%
-% At start all values are declared as global options. At the Lua side
-% all values are now stored in the |registry.global_options| table.
-%
-% \begin{macrocode}
-\cloze@set@to@global
-% \end{macrocode}
-%
-% We use the abbreviation |CLZ| for \emph{cloze} as family name and
-% prefix.
