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} %----------------------------------------------------------------------- % Usage %----------------------------------------------------------------------- \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. %% % \cloze %% \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{Ober\-kom\-mi\-sar\-in} \cloze{Hoch\-lei\-stungs\-flüs\-sig\-keits\-chro\-ma\-to\-gra\-phie} \cloze{Fil\-lial\-lei\-ter\-in} Kürze \cloze{Un\-ter\-neh\-mens\-steu\-er\-fort\-ent\-wick\-lungs\-ge\-setz} \cloze{Metz\-ger\-mei\-ster\-in} liegt \cloze{Ab\-teil\-ungs\-lei\-ter\-in} die \cloze{Metz\-ger\-mei\-ster\-in} \cloze{Ab\-teil\-ungs\-lei\-ter\-in} Würze \cloze{Ober\-kom\-mi\-sar\-in} \end{example} %% % \clozesetfont %% \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} %% % \clozefix %% \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 \\ \clozefix[width=5cm,align=right]{Joseph Haydn} & \clozefix{1723-1809} \\ \clozefix[width=5cm,align=right]{Wolfgang Amadeus Mozart} & \clozefix{1756-1791} \\ \clozefix[width=5cm,align=right]{Ludwig van Beethoven} & \clozefix{1770-1827} \\ \end{tabular} \end{example} %% % \clozenol %% \subsubsection{\cmd{\clozenol}} \label{sec:command-clozenol} \DescribeMacro{\clozenol} \cmd{\clozenol}\oarg{options}\marg{some text}: The macro name |clozenol| stands for \emph{“cloze no line”}. As the the name suggests this macro typesets cloze texts without a line. \begin{minted}{latex} Lorem \clozenol{ipsum dolor} sit amet. \end{minted} \begin{example} Lorem \clozenol{ipsum dolor} sit amet. \end{example} \begin{minted}{latex} Lorem \clozenol[textcolor=green]{ipsum dolor} sit amet. \end{minted} \begin{example} Lorem \clozenol[textcolor=green]{ipsum dolor} sit amet. \end{example} %% % \clozefil %% \subsubsection{\cmd{\clozefil}} \label{sec:command-clozefil} \DescribeMacro{\clozefil} \cmd{\clozefil}\oarg{options}\marg{some text}: The name of the command is inspired by \cmd{\hfil}, \cmd{\hfill}, and \cmd{\hfilll}. Only \cmd{\clozefil} fills out all available horizontal spaces with a line. \begin{example} Lorem ipsum dolor sit amet, \clozefil{consectetur adipisicing elit, sed do eiusmod.} Ut enim \clozefil{ad minim veniam} exercitation. \end{example} %% % \clozeextend %% \subsubsection{\cmd{\clozeextend}} \label{sec:command-clozeextend} \DescribeMacro{\clozeextend} \cmd{\clozeextend}\oarg{spaces}: The command |\clozeextend| adds some invisible placeholders to extend some cloze texts with blank space. \begin{minted}{latex} \begin{itemize} \item \clozefil{Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.} \item \clozefil{Ut enim ad minim veniam \clozeextend[20]} \item \clozefil{quis nostrud \clozeextend[20]} \end{itemize} \end{minted} \begin{example} \begin{itemize} \item \clozefil{Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.} \item \clozefil{Ut enim ad minim veniam \clozeextend[20]} \item \clozefil{quis nostrud \clozeextend[20]} \end{itemize} \end{example} %% % clozepar %% \subsubsection{\tt{clozepar}} \label{sec:command-clozepar} \DescribeEnv{clozepar} |\begin{clozepar}|\oarg{options} \dots \textit{some text} \dots |\end{clozepar}|: The environment \tt{clozepar} transforms a complete paragraph into a cloze text. The options |align|, |margin| and |width| have no effect on this environment. \begin{example} Lorem ipsum dolor sit amet, consectetur adipisicing elit ullamco laboris nisi. \begin{clozepar} Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum. \end{clozepar} Excepteur sint occaecat cupidatat non proident. \end{example} %% % clozebox %% \subsubsection{\tt{clozebox}} \label{sec:command-clozebox} \DescribeEnv{clozebox} |\begin{clozebox}|*\oarg{options} \dots \textit{some text} \dots |\end{clozebox}|: The environment \tt{clozebox} surrounds a text with a box. The starred version omits the line around the box. Use the options |boxwidth| and |boxheight| to specify the dimensions of the box. By default the width of the box is |\linewidth|. \begin{minted}{latex} \begin{clozebox} Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{minted} \bigskip \noindent |\clozehide| \clozehide \bigskip \begin{center} \begin{clozebox}[boxwidth=8cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{center} \bigskip \noindent |\clozeshow| \clozeshow \bigskip \begin{center} \begin{clozebox}[boxwidth=8cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{center} \paragraph{Option boxwidth} \label{sec:command-clozebox-boxwidth} See the documentation about the option \secref{sec:option-boxwidth}. \begin{minted}{latex} \begin{clozebox}[boxwidth=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{minted} \begin{center} \begin{clozebox}[boxwidth=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{center} \paragraph{Option boxheight} \label{sec:command-clozebox-boxheight} See the documentation about the option \secref{sec:option-boxheight}. \begin{minted}{latex} \begin{clozebox}[boxwidth=5cm,boxheight=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{minted} \begin{center} \begin{clozebox}[boxwidth=5cm,boxheight=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{center} \paragraph{starred} % starred \begin{minted}{latex} \begin{clozebox}*[boxwidth=5cm,boxheight=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{minted} \begin{center} \begin{clozebox}*[boxwidth=5cm,boxheight=5cm] Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. \end{clozebox} \end{center} %% % clozespace %% \subsubsection{\tt{clozespace}} \label{sec:command-clozespace} \DescribeEnv{clozespace} |\begin{clozespace}|\oarg{options} \dots \textit{some text} \dots |\end{clozespace}| \begin{minted}{latex} \begin{clozespace}[spacing=2] \clozesetfont{\ttfamily\Huge} Lorem \cloze{ipsum} dolor sit \cloze{amet}, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

The default width of the line is \tt{\getdefaults{width}}. In combination with the other cloze commands you can create for example an irregular alignment of the cloze text. \begin{minted}{latex} Ut enim ad \clozeline[width=1cm]\cloze{minim}\clozeline[width=3cm] minim veniam \end{minted} \begin{example} Ut enim ad \clozeline[width=1cm]\cloze{minim}\clozeline[width=3cm] minim veniam, \end{example} %% % \clozelinefil %% \subsubsection{\cmd{\clozelinefil}} \label{sec:command-clozelinefil} \DescribeMacro{\clozelinefil} \cmd{\clozelinefil}\oarg{options}: This command \cmd{\clozelinefil} fills the complete available horizontal space with a line.

Besides the possiblity to set \emph{global} options in the \cmd{\usepackage}\oarg{global options}\marg{cloze} declaration, the cloze package offers a special command to set \emph{global} options: \cmd{\clozeset}\marg{global options} %% % \clozeset %% \subsubsection{\cmd{\clozeset}} \label{sec:command-clozeset} \DescribeMacro{\clozeset} \cmd{\clozeset}\marg{global options}: The command can set \emph{global} options for each paragraph. \begin{minted}{latex} \clozeset{textcolor=red} Lorem \cloze{ipsum} dolor \par \clozeset{textcolor=green} Lorem \cloze{ipsum} dolor \end{minted} \begin{example} \clozeset{textcolor=red} Lorem \cloze{ipsum} dolor \par \clozeset{textcolor=green} Lorem \cloze{ipsum} dolor \end{example} \noindent \cmd{\clozeset} does not change the options within a paragraph. As you can see in the example below the last \cmd{\clozeset} applies the color green for both gaps. \begin{minted}{latex} \clozeset{textcolor=red} Lorem \cloze{ipsum} dolor \clozeset{textcolor=green} Lorem \cloze{ipsum} dolor \end{minted} \begin{example} \clozeset{textcolor=red} Lorem \cloze{ipsum} dolor \clozeset{textcolor=green} Lorem \cloze{ipsum} dolor \end{example} \clozereset %% % \clozereset %% \subsubsection{\cmd{\clozereset}} \label{sec:command-clozereset} \DescribeMacro{\clozereset} \cmd{\clozereset}: The command resets all \emph{global} options to the default values. It has no effect on the \emph{local} options. \begin{minted}{latex} \clozeset{ thickness=3mm, linecolor=yellow, textcolor=magenta, margin=-2pt } \end{minted} \clozeset{thickness=3mm,linecolor=yellow,textcolor=magenta,margin=-2pt} \begin{example} Very \cloze{silly} global \cloze{options}. \end{example} \begin{minted}{latex} \clozereset \end{minted} \clozereset \begin{example} \cloze{Relax!} We can reset \cloze{those} options. \end{example} %% % \clozereset %% \subsubsection{\cmd{\clozeshow} and \cmd{\clozehide}} \label{sec:command-clozeshow} \label{sec:command-clozehide} \DescribeMacro{\clozeshow} \DescribeMacro{\clozehide} \cmd{\clozeshow} and \cmd{\clozehide}: This commands are shortcuts for \cmd{\clozeset}\marg{show} and \cmd{\clozeset}\marg{hide}. \begin{minted}{latex} \clozehide \end{minted} \clozehide \begin{example} Lorem \cloze{ipsum dolor sit} amet, consectetur \cloze{adipisicing} elit. \end{example} \begin{minted}{latex} \clozeshow \end{minted} \clozeshow \begin{example} Lorem \cloze{ipsum dolor sit} amet, consectetur \cloze{adipisicing} elit. \end{example} %% % align %% \subsubsection{\tt{align}} \label{sec:option-align} \option{align}{left/center/right}: Only the macro \cmd{\clozefix} \secref{sec:command-clozefix} takes the option \tt{align} into account. Possible values are \tt{left}, \tt{center} and \tt{right}. This option only makes sense, if the width of the line is larger than the width of the text. \newcommand{\optionsalign}[1]{% \noindent% \clozefix[align=#1,width=8cm]{Lorem ipsum}% \desc{#1}% } \begin{example} \optionsalign{left} \optionsalign{center} \optionsalign{right} \end{example} %% % boxheight %% \subsubsection{\tt{boxheight}} \label{sec:option-boxheight} |boxheight| specifies the height of a cloze box. This option has only an effect on the environment |clozebox| \secref{sec:command-clozebox}. An example can be found in the section about the environment \secref{sec:command-clozebox-boxheight}. %% % boxwidth %% \subsubsection{\tt{boxwidth}} \label{sec:option-boxwidth} |boxwidth| specifies the width of a cloze box. This option has only an effect on the environment |clozebox| \secref{sec:command-clozebox}. An example can be found in the section about the environment \secref{sec:command-clozebox-boxwidth}. %% % distance %% \subsubsection{\tt{distance}} \label{sec:option-distance} \option{distance}{dimen}: The option |distance| specifies the spacing between the baseline of the text and the gap line. The larger the dimension of the option |distance|, the more moves the line down. Negative values cause the line to appear above the baseline. The default value is \tt{\getdefaults{distance}}. \newcommand{\optiondistance}[1]{% \noindent% \clozefil[distance=#1]{Lorem ipsum dolor sit amet.} \expdesc{#1} \par% } \begin{example} \optiondistance{\getdefaults{distance}} \optiondistance{3pt} \optiondistance{-3pt} \end{example} %% % hide and show %% \subsubsection{\tt{hide} and \tt{show}} \label{sec:option-hide} \label{sec:option-show} \tt{[hide]} and \tt{[show]}: By default the cloze text is displayed. Use the option |hide| to remove the cloze text from the output. If you accidentally specify both options -- |hide| and |show| -- the last option "wins". \newcommand{\optionshow}[1]{% \noindent% Lorem ipsum \cloze[#1]{dolor sit amet}, consectetur \cloze[#1]{adipisicing} elit.% \desc{#1}% } \begin{example} \optionshow{hide} \optionshow{show} \optionshow{show,hide} \optionshow{hide,show} \end{example} %% % linecolor and textcolor %% \subsubsection{\tt{linecolor} and \tt{textcolor}} \label{sec:option-linecolor} \label{sec:option-textcolor} \option{linecolor}{color name} and \option{textcolor}{color name}: Values for both color options are color names used by the xcolor package. To define your own color use the following command: \begin{minted}{latex} \definecolor{myclozecolor}{rgb}{0.1,0.4,0.6} \cloze[textcolor=myclozecolor]{Lorem ipsum} \end{minted} \definecolor{myclozecolor}{rgb}{0.1,0.4,0.6} \newcommand{\optioncolor}[2]{% \noindent% \clozefil[#1=#2]{Lorem ipsum dolor sit amet, consectetur} % \expdesc{#2}% \par% } \begin{example} \optioncolor{textcolor}{myclozecolor} \optioncolor{textcolor}{red} \optioncolor{textcolor}{green} \end{example} \noindent You can use the same color names to colorize the cloze lines. \begin{example} \optioncolor{linecolor}{myclozecolor} \optioncolor{linecolor}{red} \optioncolor{linecolor}{green} \end{example} \noindent And now hide the clozes: \clozehide \begin{example} \optioncolor{linecolor}{myclozecolor} \optioncolor{linecolor}{red} \optioncolor{linecolor}{green} \end{example} \clozeshow %% % margin %% \subsubsection{\tt{margin}} \label{sec:option-margin} \option{margin}{dimen}: The option |margin| indicates how far the line sticks up from the text. The option can be used with the commands \cmd{\cloze}, \cmd{\clozefix} and \cmd{\clozefil}. The default value of the option is \tt{\getdefaults{margin}}. \newcommand{\optionmargin}[1]{% \noindent% Lorem ipsum \cloze[margin=#1]{dolor} sit amet.% \desc{#1}% } \begin{example} \optionmargin{0pt} \optionmargin{5mm} \optionmargin{1cm} \optionmargin{6em} \optionmargin{-4pt} \end{example} % Folgt ein Satzzeichen direkt auf eine Lücke, so findet der % Zeilenumbruch erst nach dem Satzzeichen statt. Auch ein noch so großer % Wert für |margin| beeinflusst dieses Verhalten nicht. \noindent Is a punctation mark placed directly after a gap, then the line breaks after this punctation mark. Even the most large value of |margin| does not affect this behavior. \begin{example} \clozeset{margin=3mm} \cloze{Lorem}, \cloze{ipsum}. \cloze{dolor}; \cloze{sit}: \cloze{amet}, \cloze{consectetur}. \cloze{adipisicing}; \cloze{elit}: \cloze{sed}, \cloze{do}. \cloze{eiusmod}; \cloze{tempor}. \end{example} \clozereset %% % spacing %% \subsubsection{\tt{spacing}} \label{sec:option-spacing} \option{spacing}{number}: This option provides support for setting the spacing between lines. A larger font used for the cloze texts needs more line space to avoid unsteady line distances.

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{center} \clozesetfont{\itshape} %% % tabbing %% \subsubsection{The \tt{tabbing} environment} \begin{minted}{latex} \begin{tabbing} col1 \hspace{1cm} \= col2 \hspace{1cm} \= col3 \hspace{1cm} \= col4 \\ \cloze{col1} \> \> \clozefix{col3} \\ \end{tabbing} \end{minted} \begin{example} \begin{tabbing} col1 \hspace{1cm} \= col2 \hspace{1cm} \= col3 \hspace{1cm} \= col4 \\ \cloze{col1} \> \> \clozefix{col3} \\ \end{tabbing} \end{example} %% % picture %% \subsubsection{The \tt{picture} environment} \begin{minted}{latex} \begin{picture}(320,100) \put(80,25){\cloze{Lorem}} \put(160,50){\clozefix{ipsum}} \put(240,75){\clozefil{dolor}} \end{picture} \end{minted} \begin{example} \begin{picture}(320,100) \put(80,25){\cloze{Lorem}} \put(160,50){\clozefix{ipsum}} \put(240,75){\clozefil{dolor}} \end{picture} \end{example} %% % tabular %% \subsubsection{The \tt{tabular} environment} \begin{minted}{latex} \begin{tabular}{l c} \cloze{Lorem} & \cloze{ipsum} \\ \clozefix{amet} & \clozefix{consectetur} \\ \cloze{sed} & \cloze{do} \\ \end{tabular} \end{minted} % No |c| inside because of short verbatim. \begin{example} \clozeset{width=1cm} \begin{tabular}{l c} \cloze{Lorem} & \cloze{ipsum} \\ \clozefix{amet} & \clozefix{consectetur} \\ \cloze{sed} & \cloze{do} \\ \end{tabular} \end{example} \section{Some graphics for better understanding of the node tree} \subsection{Paragraph} \noindent\includegraphics[width=\linewidth]{graphics/par} \subsection{Tabular environment} \noindent\includegraphics[width=\linewidth]{graphics/tabular} \subsection{Picture environment} \noindent\includegraphics[width=\linewidth]{graphics/picture} \DocInput{cloze.dtx} \subsection{The file cloze.lua} \inputminted{lua}{cloze.lua} \pagebreak \PrintChanges \pagebreak \PrintIndex \end{document} % % \fi % % \CheckSum{0} % % \CharacterTable % {Upper-case \A\B\C\D\E\F\G\H\I\J\K\L\M\N\O\P\Q\R\S\T\U\V\W\X\Y\Z % Lower-case \a\b\c\d\e\f\g\h\i\j\k\l\m\n\o\p\q\r\s\t\u\v\w\x\y\z % Digits \0\1\2\3\4\5\6\7\8\9 % Exclamation \!
