列表错误：使用 spaceflexible/fullflexible 列时文字替换后的空格丢失

Question

使用或时，替换listings后立即丢失空格的问题（使用 时正确显示）。下面是一个小例子，问题是替换运算符后的空格丢失了。literatecolumns=spaceflexiblecolumns=fullflexiblecolumns=flexible

注意：此问题与今天早些时候发布过一篇，但这次问题涉及替换后的空格，并且在和模式literate下该空格都会丢失（上一个问题涉及字符串替换，并且仅在模式下发生错误）。\lstinlinelstlisting\lstinline

\documentclass{article}
\usepackage{listings}
\lstset{literate=*{{+}{*}{1}}, columns=fullflexible}

\begin{document}

\noindent
\begin{tabular}{ll}
flexible & \lstinline[columns=flexible]!1 + 1!\\
spaceflexible & \lstinline[columns=spaceflexible]!1 + 1!\\
fullflexible & \lstinline!1 + 1!\\
\end{tabular}

\bigskip
\noindent
Within lstlisting environment with columns=flexible
\begin{lstlisting}[columns=flexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=spaceflexible
\begin{lstlisting}[columns=spaceflexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=fullflexible
\begin{lstlisting}
1 + 1
\end{lstlisting}

\end{document}

Answer 1

您可以使用选项keepspaces。有关更多详细信息，请参阅文档。

\documentclass{article}
\usepackage{listings}
\lstset{literate=*{+}{*}{1}, columns=fullflexible,keepspaces}

\begin{document}

\noindent
\begin{tabular}{ll}
flexible & \lstinline[columns=flexible]!1 + 1!\\
spaceflexible & \lstinline[columns=spaceflexible]!1 + 1!\\
fullflexible & \lstinline!1 + 1!\\
\end{tabular}

\bigskip
\noindent
Within lstlisting environment with columns=flexible
\begin{lstlisting}[columns=flexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=spaceflexible
\begin{lstlisting}[columns=spaceflexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=fullflexible
\begin{lstlisting}
1 + 1
\end{lstlisting}

\end{document}
