使用 latex 中的 lstdefinelanguage 为字符之间的字符串着色

Question

我想将所有方法名称的颜色改为蓝色。方法由前面的一个点和后面的一个左括号定义。示例：

.setLanguage("de");

在这里我只想要设置语言换成其他颜色。我该怎么做？我目前只能改变设置语言（

\documentclass{article}


\usepackage{graphicx,color}
\usepackage{booktabs}
\usepackage{listings}


\lstdefinelanguage{Java}{
  sensitive = true,
  keywords={},
  morecomment=[l]{//},
  morecomment=[s]{/*}{*/},
  commentstyle=\color{darkgray}\ttfamily,
  % This is where i try it
  morecomment=[s][\color{blue}\bfseries]{.}{(},
  aboveskip=2em,
  belowskip=2em,
  sensitive=true
}

\lstset{
   backgroundcolor=\color{lightgray},
   extendedchars=true,
   basicstyle=\footnotesize\ttfamily,
   showstringspaces=false,
   showspaces=false,
   numbers=left,
   numberstyle=\footnotesize,
   numbersep=7pt,
   tabsize=1,
   breaklines=true,
   showtabs=true,
   captionpos=b,
}

\begin{document}

\begin{figure}[htb]
\begin{small}
\lstinputlisting[language=Java]{test.java}
\end{small}
\caption{Service 1}
\end{figure} 

\end{document}

Answer 1

虽然不是一个优雅的答案，但它确实有效。只需为和之间的内容定义另一组注释(，而)无需任何格式。

\documentclass{article}

\usepackage{graphicx,xcolor}
\usepackage{booktabs}
\usepackage{listings}

\lstdefinelanguage{Java}{
    sensitive = true,
    keywords={},
    morecomment=[l]{//},
    morecomment=[s]{/*}{*/},
    commentstyle=\color{darkgray}\ttfamily,
    % This is where i try it
    moredelim=*[s][\color{blue}\bfseries]{.}{(},
    moredelim=*[s][]{(}{)}, % <-- additional setting
    aboveskip=2em,
    belowskip=2em,
    sensitive=true
}

\lstset{
    backgroundcolor=\color{lightgray},
    extendedchars=true,
    basicstyle=\footnotesize\ttfamily,
    showstringspaces=false,
    showspaces=false,
    numbers=left,
    numberstyle=\footnotesize,
    numbersep=7pt,
    tabsize=1,
    breaklines=true,
    showtabs=true,
    captionpos=b,
}

\begin{filecontents*}{test.java}
a.setLanguage("de");
b.hello("world");
\end{filecontents*}

\begin{document}
    
\begin{figure}[htb]
    \begin{small}
        \lstinputlisting[language=Java]{test.java}
    \end{small}
    \caption{Service 1}
\end{figure} 
    
\end{document}
