How to set the default typewriter font?

Question

I'd like to select a new font for the monospaced text such as those parts within a \texttt{} and code snippets in the minted context. (As far as I can tell, minted just uses the document's default typewriter font, so I don't think I need to touch its settings.) I just want to change to another monospaced font that looks all right and has a normal tilde character. How do I do that?

Answer 1

It's the \ttdefault command which normally takes care of this.

\documentclass{article}
\begin{document}
\texttt{How to use a typewriter font}% CM default typewriter font
\par
\renewcommand\ttdefault{cmvtt} % selects CM typewriter proportional font
\texttt{How to use a typewriter font}
\par
\renewcommand{\ttdefault}{pcr} % selects Courier font
\texttt{How to use a typewriter font}      
\end{document}

But indeed it's usually best to let dedicated packages as beramamono do this, since there can be a lot of subtleties behind fonts (of which I'm often not aware myself :-)

Answer 2

\usepackage[scaled=0.8]{FiraMono}

Put the above line in the preamble of your document, i.e. immediately after \documentclass. That's it!

Since this just got bumped back up to the front page, I’ll add for completeness: in fontspec, use \setmonofont.
