[Tex/LaTex] Alternative commandchars in fancyvrb

fancyvrb

In my Verbatim I need to specify colour for my code.

In this answer (fancyvrb alternate commandchars and \textcolor) the solution is to put this code in the preamble:

\newcommand*{\fvtextcolor}[1]{\textcolor{#1}{#2}}

and then use 

\begin{Verbatim}[commandchars=&\[\]]
&fvtextcolor[blue][function]
\end{Verbatim}

My problem is the commandchars. \textcolor needs a pair of braces, but in my code I use all the pair of braces that is: () [] {}.

So is it possible to specify another pair of commandchars? Something like
&fvtextcolor'blue''function' or &fvtextcolor"blue""function"?

Best Answer

In theory, any unused characters would do, but unfortunately for certain characters this conflicts with other parts of verbatim typesetting.

I've found out that

[commandchars=\&\"\!]

gives the expected result.

The characters that are likely not to work are

` < > , ' -

If you really need some of them, a workaround can be devised.
