framedmarkdownpandocquoting
I have a Markdown file that I'm converting to PDF with Pandoc. And I'd like that the block quotation of the Markdown file get a 1px black border around them in the PDF.
I already managed to edit the style of code blocks with \lstset, but I'm not sure how to do the same for block quotations.
The "large white rectangle over the text" is actually a large Azure rectangle under the text. You can see this by changing the text colour to something else (black, for example). This colour is positioned by the snugshade environment which comes from the framed package. It's colour is determined by the colour shadecolor. To remove it altogether, remove the \begin{snugshade} and \end{snugshade} from the definition of the shadequote environment. To just change the colour, replace the Azure by something more fitting, say Maroon.

(See Update at the end, to get proper colors)
By default pandoc uses its own highlighting engine, but it can be changed to use package listings instead. Simply add --listings option to your pandoc command line.
However, the format used by listings does not break long lines either, but you can prepare all the required options in a separate tex file, for example:
% Contents of listings-setup.tex
\usepackage{xcolor}
\lstset{
basicstyle=\ttfamily,
numbers=left,
numberstyle=\footnotesize,
stepnumber=2,
numbersep=5pt,
backgroundcolor=\color{black!10},
showspaces=false,
showstringspaces=false,
showtabs=false,
tabsize=2,
captionpos=b,
breaklines=true,
breakatwhitespace=true,
breakautoindent=true,
linewidth=\textwidth
}
And then compile with the line:
pandoc test.md --listings -H listings-setup.tex -o output.pdf
Unfortunately, this solution cannot use the --highlight-style option too. If you want to get the tango colorscheme, you have to code it yourself as options for the listing packages, and include them in the \lstset above.
Given the file test.md as follows:
% Title
% Author
# First section
Some code with long lines:
```java
public class Test {
static Set<Thread> updateThreads = new HashSet<Thread>();
public static void main(String[] args) {
ConcurrentMap<Integer, String> concurrentMap = new ConcurrentHashMap<Integer, String>();
for (int i = 0; i < 1000; i++) {
startUpdateThread(i, concurrentMap);
}
for (Map.Entry<Integer, String> entry : concurrentMap.entrySet()) {
System.out.println("Key :" + entry.getKey() + " Value:" + entry.getValue());
}
for (Thread thread : updateThreads) {
thread.interrupt();
}
}
}
```
That's it.
The result generated by the previous pandoc command line is:
In order to mimic closely the result obtained with --highlight-style tango option (and no listings package), I ran pandoc asking for the intermediate .tex file to discover how the colors were defined for that case.
I wrote the following setup using listings options, which use the same colors (only where applicable, for example listings has no mean to set a specific color for numeric constants or other syntactic elements). In addition I reduced the spacing among chars, which were too far apart with default setup. This is the new setup:
% Contents of listings-setup.tex
\usepackage{xcolor}
\lstset{
basicstyle=\ttfamily,
numbers=left,
keywordstyle=\color[rgb]{0.13,0.29,0.53}\bfseries,
stringstyle=\color[rgb]{0.31,0.60,0.02},
commentstyle=\color[rgb]{0.56,0.35,0.01}\itshape,
numberstyle=\footnotesize,
stepnumber=1,
numbersep=5pt,
backgroundcolor=\color[RGB]{248,248,248},
showspaces=false,
showstringspaces=false,
showtabs=false,
tabsize=2,
captionpos=b,
breaklines=true,
breakatwhitespace=true,
breakautoindent=true,
escapeinside={\%*}{*)},
linewidth=\textwidth,
basewidth=0.5em,
}
Using those settings, i.e. running pandoc with options:
pandoc test.md --listings -H listings-setup.tex -o output.pdf
the following result is obtained:
For reference, compare it with the result without --listings but with --highlight-syntax tango instead:
As you can see, the style is very close (except for numeric constants, which are blue using tango, but black using listings). Note also how the lines were wrapped with listings. I also added line numbers which refer to the original lines (before wrapping).

Following a similar technique than the one in Pandoc: Markdown to PDF, without cutting off code block lines that are too long you can write a file named, for example
quote-setup.texcontaining:and compile with:
IMHO, the frame is "too agressive" visually. I would prefer a more subtle effect such as a shaded background. This can be achieved with:
So, for example:
will produce:
