I'm using pandoc with xelatex engine to convert markdown to pdf. I'm running pandoc like this:
pandoc -s 'backbone-fundamentals'.md -o 'backbone-fundamentals'.pdf \
--title-prefix 'Developing Backbone.js Applications' \
--normalize \
--smart \
--toc \
--latex-engine=`which xelatex`
If a code line is longer than the pdf document width it just gets cutoff. Is there anyway to have pandoc text wrap long code lines?
If you have a recent installation of LaTeX that includes the fvextra package, then there is a simple solution, recently suggested by jannick0.
Modify your YAML header options to include
\usepackage{fvextra}
\begin{Highlighting}[breaklines,numbers=left]
and compile with xelatex.
For instance,
---
header-includes:
- \usepackage{fvextra}
- \DefineVerbatimEnvironment{Highlighting}{Verbatim}{breaklines,commandchars=\\\{\}}
---
~~~~~{.java}
this is a very long long long long long long long long long long long long long line which is broken
~~~~~~
when compiled with
pandoc input.md --pdf-engine=xelatex -o output.pdf
gives 
If you had the .numberLines option, i.e.,
---
header-includes:
- \usepackage{fvextra}
- \DefineVerbatimEnvironment{Highlighting}{Verbatim}{breaklines,commandchars=\\\{\}}
---
~~~~~{.java .numberLines}
this is a very long long long long long long long long long long long long long line which is broken
~~~~~~
then the same command would produce
