我根据以下评论的建议重写了该帖子，并提供了 MWE。

问题

在生成论文末尾的参考文献列表时，PDF 输出有两个我无法解决的问题。

1) 链接溢出页面边框但应在破折号处分页。

2） 书目项目分为多页，但应保持为一个块。

问题

我的文档

我正在使用 RMarkdown 和 Pandoc 生成基于以下内容的 PDFhttp://rmarkdown.rstudio.com/authoring_pandoc_markdown.html#citations

根据文档，参考文献列表位于文档末尾。因此，我没有任何类似的东西\printbibliography。

在 RStudio 中使用“knit pdf”似乎执行：

/Applications/RStudio.app/Contents/MacOS/pandoc/pandoc +RTS -K512m -RTS MWE.utf8.md 
--to latex 
--from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash 
--output MWE.tex 
--template /usr/local/lib/R/3.3/site-library/rmarkdown/rmd/latex/default-1.15.2.tex 
--highlight-style tango 
--latex-engine /Library/TeX/texbin/xelatex 
--variable graphics=yes 
--bibliography library.bib 
--filter /Applications/RStudio.app/Contents/MacOS/pandoc/pandoc-citeproc

答案1

对于问题 1，我在header-includes:

\def\UrlBreaks{\do\/\do-\do?}

它添加了可导致 url 中断的额外字符，这显然可以在 hyperref 已加载时完成。

问题 2 的解决方案对我来说不起作用。

答案2

感谢@jon 和@moewe，问题 1\PassOptionsToPackage{hyphens}{url}可以通过在加载之前放置来解决hyperref（ ）。 在我的情况下，这在RMarkdown YAML 中\usepackage{hyperref}是不可能的，因为它使用了一些已经加载的默认 .tex 文件。 对我来说，修改默认 .text 文件是可以的。header-include:hyperref

关于问题 2显然，使用 Pandoc 和 CSL 的 RMarkdown 会为每个参考书目项目生成以下格式的段落（以空行分隔）

\hypertarget{ref-Boner2015}{}
Bonér, J. (2015). \emph{Interview with Tony Rae Moore: Typesafe AMA
Podcast Ep. 03 feat. How Akka Actors Help Build Microservices with Jonas
Bonér}. {[}Online{]}. Available from:
\url{https://www.lightbend.com/blog/typesafe-ama-podcast-ep-03-feat-akka-actors-microservices-jonas-boner}.
{[}Accessed: 22 November 2016{]}.

通常情况下，根据如何避免段落内分页？这会起作用：

\widowpenalties 1 10000
\raggedbottom

但是，阻止\hypertarget分页符（多个 \hypertarget 是否溢出页面？）。因此，另外，我必须\leavevmode在每个前面放置一个\hypertarget，从而导致覆盖\hypertarget：

\usepackage{letltxmacro}
\LetLtxMacro{\oldhypertarget}{\hypertarget}
\renewcommand{\hypertarget}[2]{\leavevmode\oldhypertarget{#1}{#2}}
