列表对齐问题

Question

我有一个后续问题这个帖子 我正在使用 中的列表beamer。 中的内容listings被推得比幻灯片上的其他内容更靠左。 我正在使用下面的代码来纠正它，它工作正常。 但是，在列中，代码现在也向右移动，即使它在注释中完全对齐。 我该如何防止这种情况？

以下是一份简单的文档：

\makeatother

\usepackage{listings} % display code on slides; don't forget [fragile] option after \begin{frame}
\usepackage{bera} % font for code in slides
\usepackage{color}
\definecolor{lightgrey}{rgb}{0.92,0.92,0.92} % defining color for listing
\definecolor{darkgreen}{rgb}{0,0.6,0} % defining color for listing

}

\usepackage{calc}
\newlength\listingnumberwidth
\setlength\listingnumberwidth{\widthof{00} + 1em}
\lstset{

xleftmargin=\listingnumberwidth,
numbersep=1em
}

% move text box

 \setbeamersize{text margin right=0.5cm}

这种向右移动是由于行首有额外的空格。可以通过添加[gobble=12]选项删除前 12 个空格来消除此问题，结果如下：

笔记：

• 请注意，您的大部分前言都不需要说明问题。我在下面 MWE 中注释掉了其中几行。在发布 MWE 之前，应删除所有不会导致问题的软件包。
