Good monospace font for code in LaTeX?

Question

I'm currently working on my dissertation and am using Palatino for text with the Euler font for mathematics. As part of my work I'll be presenting quite a few code examples, and was wondering if someone could suggest a good monospace font to go with them. As an alternative I was thinking of using the Concrete Roman and Euler font package (ala Knuth's Concrete Mathematics).

Answer 1

I personally think that Knuth's typewriter fonts are still very good, an alternative is charter and bera mono if you can get them.

 \usepackage[charter]{mathdesign}
 \def\rmdefault{bch} % not scaled
 \def\ttdefault{blg}

Also check Different approach to literate programming for LaTeX for some typesetting settings for listings.

Answer 2

Inconsolata might be a choice. There is also a package for TeX support.

It's font "designed for code listings and the like, in print," posing itself as a better alternative since many other fonts are designed for screen and not for the high resolutions in print.

\documentclass{article}
\usepackage{inconsolata}
\begin{document}
\texttt{This is Inconsolata.}
\end{document}

As seen it replaces the \tt, but this behavior can be changed.
