Question

I’m using LaTeX‘s ‘listings‘ package to format source code. Unfortunately I get curly quotes instead of straight quotes. Since the curly quotes don’t always point in the right direction, it looks bad. How can I get straight quotes instead?

I’d prefer not to change or filter the source code itself. Filtering the code to properly change ‘ to “ or ” would work, but this is easier done than said with multiple quotes on a line, or quotes spanning multiple lines. Or you could use symbol or a host of other things. But I’d really like to keep the source unchanged.

Example LaTeX:

\documentclass{article} \usepackage{listings} \begin{document} \begin{lstlisting} Fahrenheit=input('What is the Fahrenheit temperature?') Celsius=(5.0/9.0)*(Fahrenheit-32) print'The temperature is',Celsius,'degrees Celsius' \end{lstlisting} \end{document} 

Example output (using Miktex on windows):

Answer 1

Have you considered using a monospaced (typewriter) font for the listing? The following example works:

\documentclass{article} \usepackage{listings} \lstset{basicstyle=\ttfamily} % <<< This line added \begin{document} \begin{lstlisting} Fahrenheit=input('What is the Fahrenheit temperature?') Celsius=(5.0/9.0)*(Fahrenheit-32) print'The temperature is',Celsius,'degrees Celsius' \end{lstlisting} \end{document}
