從來源導入時引用的程式碼會改變顏色

Question

當我在 Latex 中引用一些 C++ 時，我編寫了一個簡單的程式碼來突出顯示語法。但是，當直接從原始檔案匯入程式碼時，標題為藍色而不是綠色，這是程式碼之間的唯一區別。

1) 直接硬編碼的 C++ 程式碼的輸出

2) 檔案中 C++ 程式碼的輸出，透過以下方式導入：

\lstinputlisting[language=C++, firstline=1, lastline=10]{Hello.cpp}

如您所見，標題現在是藍色的！

這是我用來執行此操作的乳膠程式碼：

\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{fullpage}

\newcommand{\grayScale}{0.95} % Can change the gray level here
\definecolor{codeBackground}{rgb}{\grayScale ,\grayScale ,\grayScale}
\definecolor{forestGreen}{rgb}{0.13,0.55,0.13}

\begin{document}

% Using typewriter font: \ttfamily inside \lstset
\lstset{
    language=C++,
    backgroundcolor=\color{codeBackground},
    tabsize=4,
    showstringspaces=false,
    showtabs=false,
    showspaces=false,
    basicstyle=\ttfamily,
    identifierstyle=\ttfamily,
    keywordstyle=\color{blue},
    stringstyle=\color{red},
    commentstyle=\color{gray},
    numberstyle=\color{magenta},
    morecomment=[l][\color{forestGreen}]{\#}                
}
\lstset{literate=% Colors the digits
   *{0}{{{\color{red!20!violet}0}}}1
    {1}{{{\color{red!20!violet}1}}}1
    {2}{{{\color{red!20!violet}2}}}1
    {3}{{{\color{red!20!violet}3}}}1
    {4}{{{\color{red!20!violet}4}}}1
    {5}{{{\color{red!20!violet}5}}}1
    {6}{{{\color{red!20!violet}6}}}1
    {7}{{{\color{red!20!violet}7}}}1
    {8}{{{\color{red!20!violet}8}}}1
    {9}{{{\color{red!20!violet}9}}}1
}
\begin{lstlisting}
% HERE IS MY HARDCODED C++
#include<stdio.h>
#include<iostream>
// Template for C++ quoting
/*
    Warning: If line too long, will go outside the color box
*/
int main(void)
{
    cout << "Hello World" << endl;
    return 0; // Numbers are colored when not in comment nor strings
}
\end{lstlisting}

% FROM A SOURCE FILE
\lstinputlisting[language=C++, firstline=1, lastline=10]{Hello.cpp}

\end{document}

如果您指定完全相同的設定（即沒有指定），它會起作用：

\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{fullpage}

\newcommand{\grayScale}{0.95} % Can change the gray level here
\definecolor{codeBackground}{rgb}{\grayScale ,\grayScale ,\grayScale}
\definecolor{forestGreen}{rgb}{0.13,0.55,0.13}

\begin{document}

% Using typewriter font: \ttfamily inside \lstset
\lstset{
    language=C++,
    backgroundcolor=\color{codeBackground},
    tabsize=4,
    showstringspaces=false,
    showtabs=false,
    showspaces=false,
    basicstyle=\ttfamily,
    identifierstyle=\ttfamily,
    keywordstyle=\color{blue},
    stringstyle=\color{red},
    commentstyle=\color{gray},
    numberstyle=\color{magenta},
    morecomment=[l][\color{forestGreen}]{\#}
}
\lstset{literate=% Colors the digits
   *{0}{{{\color{red!20!violet}0}}}1
    {1}{{{\color{red!20!violet}1}}}1
    {2}{{{\color{red!20!violet}2}}}1
    {3}{{{\color{red!20!violet}3}}}1
    {4}{{{\color{red!20!violet}4}}}1
    {5}{{{\color{red!20!violet}5}}}1
    {6}{{{\color{red!20!violet}6}}}1
    {7}{{{\color{red!20!violet}7}}}1
    {8}{{{\color{red!20!violet}8}}}1
    {9}{{{\color{red!20!violet}9}}}1
}
\begin{lstlisting}
% HERE IS MY HARDCODED C++
#include<stdio.h>
#include<iostream>
// Template for C++ quoting
/*
    Warning: If line too long, will go outside the color box
*/
int main(void)
{
    cout << "Hello World" << endl;
    return 0; // Numbers are colored when not in comment nor strings
}
\end{lstlisting}

\lstinputlisting[firstline=1, lastline=12]{Hello.cpp}
