修补 tikzscale

修补 tikzscale

我正在尝试修补该软件包tikzscale。具体来说，我想从软件包中删除以下几行，因为它在我的用例[1]中不构成有用的错误。

\tikzscale@ifSizeDifference{\measuredFirst - \measuredSecond}{%
}{%
\PackageError{tikzscale}{Requested to scale unscalable graphic}{Do not set width or height for graphic in\MessageBreak #3}%
}%

我还尝试在不编辑包本身的情况下执行此操作，因为我希望与其他人（以及在 Overleaf 上）共享此文档，在这种情况下我无法请求其他人编辑他们在包上的安装，所以我尝试使用regexpatch、 或 来执行此操作xpatch。

xpatch失败：

有没有什么办法可以解决这个问题？这是一个 MWE（虽然编译时没有问题，但检查日志会发现修补失败）。

\documentclass[twocolumn,twoside]{article}

[1] 我的用例是这样的，如果它很重要：我正在编写.tikz文件，这些文件本身有\includegraphics，在 tikz 中注释。当我尝试将它们包含到我的主文档中时，它们会抛出错误Requested to scale unscalable graphic，但是，文档可以正确编译，但在 Overleaf 上会失败。

.tikz我试图包含的一个例子：

\begin{tikzpicture}
    \node[anchor=south west,inner sep=0] (image) at (0,0){
        \includegraphics[width=0.95\linewidth]{figure2.pdf}
    };
    \begin{scope}[x={(image.south east)},y={(image.north west)}]
        % (a) (b) (c) (d) labels
        \node at (0.02,0.97){\textbf{(a)}};
        \node at (0.40,0.97){\textbf{(b)}};
        \node at (0.67,0.97){\textbf{(c)}};
        \node at (0.21,0.66){\textbf{(d)}};
        \node at (0.02,0.39){\textbf{(e)}};

        % Inset label
        \fill [white] (0.23,0.53) rectangle (0.30,0.62);
        \fill [white] (0.65,0.53) rectangle (0.75,0.62);
        \node at (0.67,0.41) {Diffraction losses};
        \node[anchor=south west] at (0.23,0.53) {$\bm{|\psi\rangle}$};
        \node[anchor=south west] at (0.65,0.53) {$\bm{T|\psi\rangle}$};

        % Optical component labels
        \node at (0.14,0.35){\small Laser};
        % \node at (0.07,0.32){\small Fiber};
        \node at (0.14,0.01){\small Pol$_1$};
        \node at (0.23,0.01){\small HWP};
        \node at (0.31,0.01){\small BS};
        \node at (0.30,0.32){\small Det$_B$};
        % \node at (0.40,0.01){\small Lens};
        % \node at (0.46,0.35){\small Metasurface};
        % \node at (0.53,0.01){\small Lens};
        \node at (0.46,-0.02){\small Metasurface};
        \node at (0.70,0.01){\small Fourier lens};
        \node at (0.74,0.20){\small QWP};
        \node at (0.83,0.20){\small Pol$_2$};
        \node at (0.95,0.03){\small Det$_A$};

        %\draw[red,ultra thick,rounded corners] (0.62,0.65) rectangle (0.78,0.75);
    \end{scope}
\end{tikzpicture}

该命令\tikzscale@scaleTikzpictureTo是用 定义的\NewDocumentCommand，既不支持xpatch也不regexpatch支持直接修补此类命令。

如果你\xshowcmd\tikzscale@scaleTikzpictureTo在尝试补丁之前这样做，你会看到

> \tikzscale@scaleTikzpictureTo=\protected
macro:->\__xparse_start_expandable:nNNNNn {mmm}\tikzscale@scaleTikzpictureTo 
\tikzscale@scaleTikzpictureTo  \tikzscale@scaleTikzpictureTo code
?{\__xparse_expandable_grab_m:w \__xparse_expandable_grab_m:w
\__xparse_expandable_grab_m:w }.

在控制台上，这清楚地解释了为什么补丁不起作用：您想要替换的文本从一开始就不存在。

了解一点xparse就能知道要修补的真正宏是什么。提示：它的名称中有一个空格；\expandafter可以使用标准技巧将其作为参数传递给\xpatchcmd。

还要注意\regexpatchcmd需要l3regex语法（中的第 XXVI 部分interface3.pdf）；您使用了适合的语法\xpatchcmd。
