在 \lstinputlisting 中，linebackgroundcolor 覆盖 backgroundcolor

Question

我正在尝试在\lstinputlisting已有背景颜色的环境中突出显示特定行。我尝试的方法删除了原始背景颜色，仅突出显示特定行。

如何保留原始背景颜色和只突出显示特定的行？

以下是我目前所掌握的信息：

\documentclass{book}

\usepackage{listings}
\usepackage{lstlinebgrd}
\usepackage{xcolor}
\usepackage[numbered,framed]{matlab-prettifier}
\usepackage{filecontents}

\begin{filecontents*}{\jobname.m}
 % detect if next step is an obstacle
                if bug.isoccupied(robot + [dx; dy])
                    bug.message('(%d,%d) obstacle!', n);
                    bug.H(bug.j,:) = robot; % define hit point
                    bug.step = 2;
                    % get a list of all the points around the obstacle
                    bug.edge = edgelist(bug.occgridnav == 0, robot);
                    %bug.k = 2;  % skip the first edge point, we are already there
                    bug.k = size(bug.edge,2)
                else
                    n = robot + [dx; dy];
                end
            end % step 1
\end{filecontents*}


\lstdefinestyle{mystyle}{
numbers=left,
numberstyle=\small,
numbersep=8pt,
%language=Matlab,
style=Matlab-editor,
basicstyle=\mlttfamily\scriptsize,
%numbersep=22pt,
backgroundcolor=\color{blue!10}
}


\begin{document}


\lstinputlisting[firstnumber = 236,
style=mystyle,
linebackgroundcolor={\ifnum\value{lstnumber}=244\color{green}\fi},
caption={[First Change to the Bug2 Algorithm]{First Change to the Bug2 Algorithm}},
label = mat:line246]{\jobname.m}

\end{document}

如果将背景颜色也添加到线条颜色中，它似乎可以工作。另一种方法是修补内部命令以添加背景颜色：

\documentclass{book}

\usepackage{listings}
\usepackage{lstlinebgrd}
\usepackage{xcolor}
\usepackage[numbered,framed]{matlab-prettifier}
\usepackage{filecontents}

\begin{filecontents*}{\jobname.m}
 % detect if next step is an obstacle
                if bug.isoccupied(robot + [dx; dy])
                    bug.message('(%d,%d) obstacle!', n);
                    bug.H(bug.j,:) = robot; % define hit point
                    bug.step = 2;
                    % get a list of all the points around the obstacle
                    bug.edge = edgelist(bug.occgridnav == 0, robot);
                    %bug.k = 2;  % skip the first edge point, we are already there
                    bug.k = size(bug.edge,2)
                else
                    n = robot + [dx; dy];
                end
            end % step 1
\end{filecontents*}


\lstdefinestyle{mystyle}{
numbers=left,
numberstyle=\small,
numbersep=8pt,
%language=Matlab,
style=Matlab-editor,
basicstyle=\mlttfamily\scriptsize,
%numbersep=22pt,
backgroundcolor=\color{blue!10}
}
\usepackage{xpatch}
\makeatletter
%alternative: patch \lst@bkgcolor 
%\xpatchcmd\lst@linebgrd{\color{-.}}{\lst@bkgcolor}{}{\fail}
\makeatother

\begin{document}


\lstinputlisting[firstnumber = 236,
style=mystyle,
%add background color to all lines:
linebackgroundcolor={\color{blue!10}\ifnum\value{lstnumber}=244\color{green}\fi},
caption={[First Change to the Bug2 Algorithm]{First Change to the Bug2 Algorithm}},
label = mat:line246]{\jobname.m}
