在 tikz-cd 中自动显示节点标签

CoDi 软件包具有一项prompter功能，启用后，它会将每个节点放入一个框中，并用其对象名称进行标记（请参阅CoDi 手册)：

是否可以做tikz-cd类似的事情，根据网格位置标记图中的非空节点？

例子：这样的选项应该可以改变图表

答案1

这不是我的答案，而是一位朋友的答案。重要的信息似乎是行和列索引分别存储在 TeX 计数\pgfmatrixcurrentrow和中\pgfmatrixcurrentcolumn。然后可以使用它们来自动标记非空单元格。

\usepackage{tikz-cd}

\begin{tikzcd}[row sep={4.5em,between origins}, 
    column sep={4.5em,between origins}, ampersand replacement=\&,
    nodes in empty cells=false,
    cells={
    nodes={draw,
        execute at end node={%
            \makebox[0pt][l]{$~~{}_{\the\pgfmatrixcurrentrow-\the\pgfmatrixcurrentcolumn}$}}
        }
        }

答案2

这是 user237902 答案的一个很小的变化：使用\tikzcdset，可以创建密钥prompter，prompter all如

\tikzcdset{%
    prompter/.code={%
        \tikzset{%
            nodes in empty cells=false,cells={nodes={draw,execute at end node={\makebox[0pt][l]{$~~{}_{\the\pgfmatrixcurrentrow-\the\pgfmatrixcurrentcolumn}$}}}}
        }%
    }%
}%
\tikzcdset{%
    prompter all/.code={%
        \tikzset{%
            nodes in empty cells=true,cells={nodes={draw,execute at end node={\makebox[0pt][l]{$~~{}_{\the\pgfmatrixcurrentrow-\the\pgfmatrixcurrentcolumn}$}}}}
        }%
    }%
}%

能够\begin{tikzcd}以 的形式调用此功能\begin{tikzcd}[prompter]。以下是示例：

\documentclass{article}
\usepackage{tikz-cd}
\tikzcdset{%
    prompter/.code={%
        \tikzset{%
            nodes in empty cells=false,cells={nodes={draw,execute at end node={\makebox[0pt][l]{$~~{}_{\the\pgfmatrixcurrentrow-\the\pgfmatrixcurrentcolumn}$}}}}
        }%
    }%
}%
\tikzcdset{%
    prompter all/.code={%
        \tikzset{%
            nodes in empty cells=true,cells={nodes={draw,execute at end node={\makebox[0pt][l]{$~~{}_{\the\pgfmatrixcurrentrow-\the\pgfmatrixcurrentcolumn}$}}}}
        }%
    }%
}%
\begin{document}
\begin{tikzcd}[row sep={4.5em,between origins},column sep={4.5em,between origins}, ampersand replacement=\&,prompter]%
    \&\&\&\&
    \bullet
    \arrow[rrrd]

    \\
    \&\&\&
    \bullet
    \arrow[rdd]
    \arrow[ruu]
    \&\&\&\&\&
    \\
    \bullet
    \arrow[rrru]
    \arrow[ruu]
    \&\&\&\&\&\&\&\&
    \\
    \&\&\&\&
    \bullet
    \arrow[rrrr]
    \&\&\&\&
    \bullet
    \\
    \&\&
    \bullet
    \arrow[rrrr]
    \arrow[luuuu]
    \&\&\&\&
    \bullet
    \arrow[rddd,bend right]
    \arrow[rddd,bend left]
    \arrow[ruuuu]
    \&\&
    \\
    \bullet
    \arrow[rrrd]
    \arrow[uuu]
    \&\&\&\&\&\&\&\&
    \\

而相同的代码，但prompter替换prompter all为 在此处输入图片描述 当然，后者相当丑陋，但根据图表，此功能可能很有用。

进一步的美学变化是将键更改prompter为prompter all以下内容：

答案3

如果您提供 MWE，可能会有所帮助。我想像我的示例一样，根据节点的坐标来标记节点，对吗？节点 4-(-4) 的坐标为 4 和 -4？

\documentclass[border=1.21cm]{standalone}
\usepackage{tikz}

\begin{document}
    
    \begin{tikzpicture}
        
        \foreach\x/\y in {0/0,2/2,4/-4}
        \draw[] (\x,\y)  node[fill=white,draw=black,rectangle,inner sep=2pt] {\x-\y};
