fancyvrbspacingverbatim
From the fancyvrb documentation, it looks like I can set left and right margins (paragraph 4.1.13) only. How can I set the top margin for my environment?
More specifically, given that I have a frame and a top title in my environment, I would like some extra padding between the top frame and the first line of text.
\newcommand{\shellheader}{This is a Shell}
\DefineVerbatimEnvironment{shell}{Verbatim}
{label=\shellheader,frame=single}
I am afraid fancyvrb doesn't allow what you want to do; a possible workaround would be using the listings package instead of (or together with) fancyvrb (listings offers automatic line breaking and many other useful features; please refer to the package documentation for details). You can keep your current example environment in the document body, and simply define it using listings in your preamble; something like this:
\documentclass{article}
\usepackage{listings}
\lstset{%
basicstyle=\ttfamily,
breaklines=true,
columns=fullflexible,
escapeinside = ||,
breakindent=0pt}
\lstnewenvironment{example}{}{}
\begin{document}
\begin{example}
Foo|\\|Bar
\end{example}
\end{document}
You just need to move the - somewhere safe, for example:
\documentclass{article}
\usepackage{fancyvrb}
\DefineVerbatimEnvironment{terminal}{Verbatim}{commandchars=\\\{\}}
\newcommand\somefile{\input{some-file}}
\begin{document}
\begin{terminal}
\somefile
\end{terminal}
\end{document}

I propose a horrible hack that should take into account all your needs:
Act on
