退出列表时遇到的问题

我想使用 LaTeX 来记录我的 C++ 代码，因为我能够轻松排版数学，以及使用 TikZ 创建图表。我制作了一个最小的 LaTeX 模板进行测试，但我已经遇到了一些我想修复的问题：

  • 转义的 LaTeX 代码中，每行文本的末尾不会生成空格（如果您查看下面的渲染输出，您应该会看到一些单词粘在一起）。
  • 我希望转义的 LaTeX 代码中的环境保持在阴影边界内，行号位于每行的左侧（其余代码也是如此）。特别是，我希望强制源代码行号与其在 PDF 中的渲染输出之间保持 1:1 的对应关系。

您能建议如何解决这些问题吗？理想情况下，我还希望能够在文档中包含 TikZ 图片，这样图表占用的代码行数与我用来创建它的转义 LaTeX 代码的长度完全相同。但如果这太难实现，那么没有它我也可以接受。

非常感谢您的宝贵时间！

** Template Parameters:

`\begin{enumerate}
\item[Schedule] A forward iterator that traverses the edge ordering that
ought to be used for each iteration.
\item[EdgeToFactorMap] A map of edges to factors. We can always transform a
graph such that the node potentials are subsumed into the edge potentials, so
this constraint does not result in a loss of generality.
\item[MessageFunc] A function used to compute the message
$\delta_{i \rightarrow j}$. It should accept as parameters the following:
\begin{itemize}
     \item A const reference to a factor along $E_{ij}$.
     \item A reference to the target factor to be written to.
     \item The starting and ending iterators to a container of factors
     representing the messages received by the sending clique, $C_{i}$.
     \item The starting and ending iterators to a container of factors
     representing the messages received by the receiving clique, $C_{j}$.

memory for the algorithm.

答案1

我不太了解这个listings包，所以可能有一个更高级别的接口，但我会

  1. 使用description而不是，enumerate这样 laTex 就可以预期更宽的标签，而不会将它们粘贴在左边距
  2. 定义行尾字符以吞噬两个**（如果存在）并增加行计数器。（实际上，如果您同时允许正常的乳胶排版，则排版行号会更难）
  3. 我也注释掉了，adforn因为我没有它。

答案2

我有一些部分解决方案，所以我会在想出解决方案时发布它们。在简单情况下，可以通过附加以下内容来解决缩进问题

\def\leftoff{1.5in}
\setlength{\leftmargini}{\leftmargini+\leftoff}
\setlength{\leftmarginii}{\leftmarginii+\leftoff}

到序言。这修复了简单的用例，但在环境enumerate嵌套在另一个环境中的情况下添加了多余的缩进。因此，我建议您不要enumerate在源代码中使用环境（表格内部除外），而是将环境用作tabular最外层的容器。这样可以更好地利用空间，并注意设置适当的边距。
