如何使用 logicpuzzle 包在数独单元中写入提示？

Question

我需要用 LaTeX 排版数独表格，到目前为止，我已经能够使用该logicpuzzle软件包完成大部分工作。缺少的少数功能之一是能够在单元格内写入提示，列出可以放入该单元格的所有可能数字。

看看包装文档，我没有看到单独使用包来执行此操作的选项，所以我想知道是否应该完全使用不同的包，或者是否有办法扩展logicpuzzle以使其显示这一点。

到目前为止，我所拥有的如下：

\documentclass{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage{logicpuzzle}

\begin{document}

\tableofcontents
\newpage

\chapter{Sudoku 1}

\begin{logicpuzzle}[rows=9,columns=9,color=orange!50,scale=1.5]
\framepuzzle
\framearea{black}{(1,7)--(4,7)--(4,10)--(1,10)}
\framearea{black}{(4,7)--(7,7)--(7,10)--(4,10)}
\framearea{black}{(7,7)--(10,7)--(10,10)--(7,10)}
\framearea{black}{(1,4)--(4,4)--(4,7)--(1,7)}
\framearea{black}{(4,4)--(7,4)--(7,7)--(7,4)}
\framearea{black}{(7,4)--(10,4)--(10,7)--(10,7)}
\framearea{black}{(1,1)--(1,4)--(4,4)--(4,1)}
\framearea{black}{(4,1)--(7,1)--(7,4)--(4,4)}
\setrow{9}{{},{},{3},{4},{},{5},{6},{},{}}
\setrow{8}{{7},{},{},{},{},{},{},{},{}}
\setrow{7}{{8},{},{},{},{},{},{},{},{}}
\setrow{6}{{9},{},{},{},{},{},{},{},{7}}
\setrow{5}{{},{},{},{},{},{},{},{},{8}}
\setrow{4}{{},{},{},{},{},{},{},{},{9}}
\setrow{3}{{},{},{},{},{},{},{},{},{}}
\setrow{2}{{},{},{},{},{},{},{},{},{}}
\setrow{1}{{},{},{},{},{},{},{},{},{}}
\fillcell{1}{9}
\fillcell{9}{9}
\end{logicpuzzle}

\end{document}

这是结果数独：

有没有办法使用该logicpuzzle包在数独单元内排版数字提示？

理想情况下，它们看起来应该类似于这个问题：

我为此定义了一些简单的宏。

\documentclass[tikz]{standalone}
\newcommand\inserthint[3]{%
    \foreach \i in {#3} {
        \ifnum\i<4
            \draw ({(#1-0.5)+(\i*0.25)},#2+0.25) node[font=\scriptsize] {\i};
        \else
            \ifnum\i>6
                \draw ({(#1-2)+(\i*0.25)},#2-0.25) node[font=\scriptsize] {\i};
            \else
                \draw ({(#1-1.25)+(\i*0.25)},#2) node[font=\scriptsize] {\i};
            \fi
        \fi
    }
}
\begin{document}
\begin{tikzpicture}
\draw[very thick,step=3] (0,0) grid (9,9);
\draw (0,0) grid (9,9);
\begin{scope}[every node/.style={minimum size=1cm},xshift=-.5cm,yshift=-.5cm]
\renewcommand{\arraystretch}{1}
\node at (1,6) {9};
\node at (1,7) {8};
\node at (1,8) {7};
\node at (3,9) {3};
\node at (4,9) {4};
\node at (6,9) {5};
\node at (7,9) {6};
\node at (9,6) {7};
\node at (9,5) {8};
\node at (9,4) {9};
\end{scope}
\begin{scope}[xshift=-.5cm,yshift=-.5cm]
\inserthint{1}{9}{1,...,9}
\inserthint{4}{6}{2,5,6,3,7}
\end{scope}
\end{tikzpicture}
\end{document}

如果需要填充，我们应该稍微重新安排一下代码。对于“普通”节点，你只需要添加 option fill=...。对于“提示”节点，我为宏添加了一个参数。

\documentclass[tikz]{standalone}
\newcommand\inserthint[4]{%
    \fill[#4] (#1-.5,#2-.5) rectangle (#1+.5,#2+.5);
    \foreach \i in {#3} {
        \ifnum\i<4
            \draw ({(#1-0.5)+(\i*0.25)},#2+0.25) node[font=\scriptsize] {\i};
        \else
            \ifnum\i>6
                \draw ({(#1-2)+(\i*0.25)},#2-0.25) node[font=\scriptsize] {\i};
            \else
                \draw ({(#1-1.25)+(\i*0.25)},#2) node[font=\scriptsize] {\i};
            \fi
        \fi
    }
}
\begin{document}
\begin{tikzpicture}
\begin{scope}[every node/.style={minimum size=1cm},xshift=-.5cm,yshift=-.5cm]
\renewcommand{\arraystretch}{1}
\node at (1,6) {9};
\node at (1,7) {8};
\node at (1,8) {7};
\node at (3,9) {3};
\node at (4,9) {4};
\node at (6,9) {5};
\node at (7,9) {6};
\node at (9,6) {7};
\node at (9,5) {8};
\node[fill=blue!30] at (9,4) {9};
\node[fill=red!30] at (2,3) {};
\end{scope}
\begin{scope}[xshift=-.5cm,yshift=-.5cm]
\inserthint{1}{9}{1,...,9}{yellow}
\inserthint{4}{6}{2,5,6,3,7}{green!50}
\end{scope}
\draw[very thick,step=3] (0,0) grid (9,9);
\draw (0,0) grid (9,9);
\end{tikzpicture}
\end{document}
