如何在输入列表中的虚线前留两个空格？

Question

我正在使用的解决方案如何在框内代码中写入行号. 其代码略有变化：

\begin{filecontents*}{\jobname.sol}
    function hello_world(uint a, uint b, uint c, uint d, uint e, uint f) public returns bool {
            uint256 amount = 100
            return amount * 100
            return true;
        }
\end{filecontents*}

好像虚线有四个空格。

是否可以将换行符大小设置为两个空格？请注意，我已将其更改tabsize=1为较小的值，但没有任何效果。

uint d举个例子，看看和之前有两个空格bool {：

function hello_world(uint a, uint b, uint c, 
  uint d, uint e, uint f) public returns bool {
  uint256 amount = 100
  return amount * 100
  return true;
}

• 如何使 tabsize 也影响 lstinputlisting？

Answer 1

使用breakindent。

\documentclass[11pt]{article}

\usepackage{amsmath,amssymb}
\usepackage{listings}
\usepackage{lstautogobble}

\lstdefinestyle{mystyle}
{
    basicstyle=\ttfamily,
    frame=single,
    breaklines,
    basewidth=0.6em,
    breakindent=1.2em,
    breakatwhitespace
}

\begin{document}

\begin{lstlisting}[style=mystyle,autogobble]
    function hello_world(uint a, uint b, uint c, uint d, uint e, uint f) public returns bool {
        uint256 amount = 100
        return amount * 100
        return true;
    }
\end{lstlisting}

\begin{lstlisting}[style=mystyle,autogobble,postbreak=\hbox{$\hookrightarrow$\space}]
    function hello_world(uint a, uint b, uint c, uint d, uint e, uint f) public returns bool {
        uint256 amount = 100
        return amount * 100
        return true;
    }
\end{lstlisting}

\end{document}

我已经basewidth明确设置了（即一个字符的宽度），以便breakindent可以精确设置为 2 个字符宽。如果您希望使用，第二个版本会打印一个钩子来区分换行符。
