我查看了一些关于向 \input 命令传递参数的线程，但发现没有太多。任何帮助解决我当前困境的帮助（或替代方法的反馈）都将不胜感激！我当前的设置（有效，但不理想）是：
main.tex 中的相关部分
\begin{tikzpicture}[scale=.3]
\input{grid}
%some other shapes
\end{tikzpicture}
网格
\draw[black!20!white] (0,0) grid (20, 20);
\fill (0,0) circle (2pt) node[below left] {(0,200)};
\fill (20,0) circle (2pt) node[below right] {(200,200)};
\fill (0,20) circle (2pt) node[above left] {(0,0)};
\fill (20,20) circle (2pt) node[above right] {(200,0)};
\fill (20,20) circle (2pt) node[above right] {(200,0)};
\tiny
\foreach \x in {20, 40, ..., 180} {
\fill (\x/10,20) circle (2pt) node[above] {\x};
}
\foreach \y in {20, 40, ..., 180} {
\fill (0,20-\y/10) circle (2pt) node[left] {\y};
}
虽然我想自定义网格。比如 -
\pgfmathsetmacro{\inc}{#1/10}
\draw[black!20!white] (0,0) grid (\inc,\inc);
\fill (0,0) circle (2pt) node[below left] {(0,#1)};
\fill (\inc,0) circle (2pt) node[below right] {(#1,#1)};
\fill (0,\inc) circle (2pt) node[above left] {(0,0)};
\fill (\inc,\inc) circle (2pt) node[above right] {(#1,0)};
\fill (\inc,\inc) circle (2pt) node[above right] {(#1,0)};
\tiny
\foreach \x in {#2, #2*2, ..., #1 - #2} {
\fill (\x/10,\inc) circle (2pt) node[above] {\x};
}
\foreach \y in {#3, #3*2, ..., #1 - #3} {
\fill (0,\inc-\y/10) circle (2pt) node[left] {\y};
}
并在 main.tex 中输入如下：
\begin{tikzpicture}[scale=.3]
\input{grid}[160][10][25]
%some other shapes
\end{tikzpicture}
或者
\begin{tikzpicture}[scale=.3]
\input{grid}[300][15][15]
%some other shapes
\end{tikzpicture}

按照@Andrew的要求，MWE（可以工作，但不理想）-
主要.tex：
\documentclass{exam}
\usepackage{tikz}
\begin{document}
\begin{center}
\begin{tikzpicture}[scale=.3]
\input{grid}
\end{tikzpicture}
\end{center}
\end{document}
网格.tex：
\draw[black!20!white] (0,0) grid (20, 20);
\fill (0,0) circle (2pt) node[below left] {(0,200)};
\fill (20,0) circle (2pt) node[below right] {(200,200)};
\fill (0,20) circle (2pt) node[above left] {(0,0)};
\fill (20,20) circle (2pt) node[above right] {(200,0)};
\fill (20,20) circle (2pt) node[above right] {(200,0)};
\tiny
\foreach \x in {20, 40, ..., 180} {
\fill (\x/10,20) circle (2pt) node[above] {\x};
}
\foreach \y in {20, 40, ..., 180} {
\fill (0,20-\y/10) circle (2pt) node[left] {\y};
}

根据@Andrew 的建议，我设法在主文件中定义变量并在 grid.tex 中使用相同的变量
主要.tex：
\documentclass{exam}
\usepackage{tikz}
\begin{document}
\begin{center}
\begin{tikzpicture}[scale=.3]
\def\gridsize{300}
\def\xMarker{45}
\def\yMarker{50}
\input{grid}
\end{tikzpicture}
\end{center}
\end{document}
网格.tex：
\pgfmathsetmacro\size{\gridsize/10}
\draw[black!20!white] (0,0) grid (\size,\size);
\fill (0,0) circle (2pt) node[below left] {(0,\gridsize)};
\fill (\size,0) circle (2pt) node[below right] {(\gridsize,\gridsize)};
\fill (0,\size) circle (2pt) node[above left] {(0,0)};
\fill (\size,\size) circle (2pt) node[above right] {(\gridsize,0)};
\fill (\size,\size) circle (2pt) node[above right] {(\gridsize,0)};
\tiny
\foreach \x in {0,\xMarker, ..., \gridsize} {
\fill (\x/10,\size) circle (2pt) node[above] {\x};
}
\foreach \y in {0,\yMarker, ..., \gridsize} {
\fill (0,\size-\y/10) circle (2pt) node[left] {\y};
}
仍然希望我能以某种方式将值传递给文件:)
我认为我无法创建命令，因为我无法将其放入 tikz 中。
答案1
你想要这样的东西吗？
\documentclass{exam}
\usepackage{tikz,xparse}
\NewDocumentCommand \mygrid { O {300} O {45} O {50} }
{
\pgfmathsetmacro\size{#1/10}
\draw[black!20!white] (0,0) grid (\size,\size);
\fill (0,0) circle (2pt) node[below left] {(0,#1)};
\fill (\size,0) circle (2pt) node[below right] {(#1,#1)};
\fill (0,\size) circle (2pt) node[above left] {(0,0)};
\fill (\size,\size) circle (2pt) node[above right] {(#1,0)};
\fill (\size,\size) circle (2pt) node[above right] {(#1,0)};
\begin{scope}[font=\tiny]
\foreach \x in {0,#2, ..., #1} {
\fill (\x/10,\size) circle (2pt) node[above] {\x};
}
\foreach \y in {0,#3, ..., #1} {
\fill (0,\size-\y/10) circle (2pt) node[left] {\y};
}
\end{scope}
}
\begin{document}
\begin{center}
\begin{tikzpicture}[scale=.3]
\mygrid[200][35][25]
\end{tikzpicture}
\begin{tikzpicture}[scale=.3]
\mygrid
\end{tikzpicture}
\end{center}
\end{document}
