我如何模仿自定义“列表（续）”标题的列表标题样式？

Question

我有以下可以正常工作的 LaTeX 代码：

\documentclass[12pt,a4paper]{article}
\usepackage[a5paper]{geometry}% just for the example
\usepackage[utf8x]{inputenc}
\usepackage{listings}
\usepackage[labelfont=bf, font=small]{caption}
\usepackage[framemethod=tikz]{mdframed}


\lstset{
breaklines=true,
breakatwhitespace=false,
xleftmargin=1em,
frame=single,
numbers=left,
numbersep=5pt,
}

\newcommand\mylstcaption{}

\surroundwithmdframed[
hidealllines=true,
middleextra={
  \node[anchor=west] at (O|-P)
    {\lstlistingname~\thelstlisting\  (Cont.):~\mylstcaption};},
secondextra={
  \node[anchor=west] at (O|-P)
    {\lstlistingname~\thelstlisting\  (Cont.):~\mylstcaption};},
splittopskip=2\baselineskip
]{lstlisting}

\begin{document}

\renewcommand\mylstcaption{Example listing of code}
\begin{lstlisting}[language=C, caption=\mylstcaption, label=lst:c1]

struct safe_buffer {
struct list_head node;

/* original request */
void    *ptr;
size_t  size;
int direction;

/* safe buffer info */
struct dmabounce_pool *pool;
void    *safe;
dma_addr_t  safe_dma_addr;
};

struct dmabounce_pool {
unsigned long   size;
struct dma_pool *pool;
#ifdef STATS
unsigned long   allocs;
#endif
};

struct dmabounce_device_info {
struct device *dev;
struct list_head safe_buffers;
#ifdef STATS
unsigned long total_allocs;
unsigned long map_op_count;
unsigned long bounce_count;
int attr_res;
#endif
struct dmabounce_pool   small;
struct dmabounce_pool   large;

rwlock_t lock;

int (*needs_bounce)(struct device *, dma_addr_t, size_t);
};

#ifdef STATS
static ssize_t dmabounce_show(struct device *dev, struct device_attribute *attr,
char *buf)
{
struct dmabounce_device_info *device_info = dev->archdata.dmabounce;
return sprintf(buf, "%lu %lu %lu %lu %lu %lu\n",
device_info->small.allocs,
device_info->large.allocs,
device_info->total_allocs - device_info->small.allocs -
device_info->large.allocs,
device_info->total_allocs,
device_info->map_op_count,
device_info->bounce_count);
}

static DEVICE_ATTR(dmabounce_stats, 0400, dmabounce_show, NULL);
#endif

\end{lstlisting}

\end{document}

现在我想要有类似的标题（相同的字体大小等），但目前情况并非如此。

Answer 1

标题标签的样式

列表标题的标题样式不适用于“继续”列表的标题。只需替换即可实现

{\captionfont{\captionlabelfont\lstlistingname~\thelstlisting\  (Cont.):}~\mylstcaption};},

为了

{\lstlistingname~\thelstlisting\  (Cont.):~\mylstcaption};},

在您的代码中（出现两次）。

标题居中

您的后续列表的标题未居中。这可以通过对 定义的节点坐标执行一些算术运算来实现mdframed。根据mdframed源代码，O和分别对应于边界框P左下角和右上角的坐标。因此对应于左上角。您想要构造位于点和中间的点（参见下图）；这就是标题应该位于的位置。tikzO|-P(O|-P)(P)

O|-P      point of interest        P
*-----------------*----------------*
|                                  |
|                                  |
|                                  |
|                                  |
|                                  |
|                                  |
|                                  |
|                                  |
*----------------------------------*
O

要构建该中点，您可以使用tikz名为的库calc，如下所示：

($.5*(O|-P) + .5*(P)$)

最后，删除anchor不再需要的规范。

笔记：请记住，如果您caption稍后更改设置（例如，如果您决定将列表标题放在左侧），您还必须相应地更改继续列表标题的位置。更自动化的方法是检查标题对齐方式并相应地放置“继续”列表的标题。也许我会这样做...稍后。
