Latex: Listings with monospace fonts

Question

This is what the code looks in Xcode.

And this in my listing created with texlive.

And yes I used basicstyle=\ttfamily . Having looked at the manual of listings I haven't found anything about fixed-with or monospace fonts..

Example to reproduce

\documentclass[   article,   a4paper,   a4wide,   %draft,   smallheadings ]{book}  % Packages below \usepackage{graphicx} \usepackage{verbatim} % used to display code \usepackage{hyperref} \usepackage{fullpage} \usepackage[ansinew]{inputenc} % german umlauts \usepackage[usenames,dvipsnames]{color} \usepackage{float} \usepackage{subfig} \usepackage{tikz} \usetikzlibrary{calc,through,backgrounds} \usepackage{fancyvrb} \usepackage{acronym} \usepackage{amsthm} % Uuhhh yet another package \VerbatimFootnotes % Required, otherwise verbatim does not work in footnotes! \usepackage{listings}  \definecolor{Brown}{cmyk}{0,0.81,1,0.60} \definecolor{OliveGreen}{cmyk}{0.64,0,0.95,0.40} \definecolor{CadetBlue}{cmyk}{0.62,0.57,0.23,0} \definecolor{lightlightgray}{gray}{0.9}  \begin{document} \lstset{ language=C,                             % Code langugage basicstyle=\ttfamily,                   % Code font, Examples: \footnotesize, \ttfamily keywordstyle=\color{OliveGreen},        % Keywords font ('*' = uppercase) commentstyle=\color{gray},              % Comments font numbers=left,                           % Line nums position numberstyle=\tiny,                      % Line-numbers fonts stepnumber=1,                           % Step between two line-numbers numbersep=5pt,                          % How far are line-numbers from code backgroundcolor=\color{lightlightgray}, % Choose background color frame=none,                             % A frame around the code tabsize=2,                              % Default tab size captionpos=b,                           % Caption-position = bottom breaklines=true,                        % Automatic line breaking? breakatwhitespace=false,                % Automatic breaks only at whitespace? showspaces=false,                       % Dont make spaces visible showtabs=false,                         % Dont make tabls visible columns=flexible,                       % Column format morekeywords={__global__, __device__},  % CUDA specific keywords }  \begin{lstlisting}     As[threadRow][threadCol] = A[         threadCol + threadRow * Awidth   // Adress of the thread in the current block         + i * BLOCK_SIZE                 // Pick a block further left for i+1         + blockRow * BLOCK_SIZE * Awidth // for blockRow +1 go one blockRow down     ]; \end{lstlisting}  \end{document} 

Answer 1

The problem is the columns=flexible option. Remove it and it looks like you want it to look. At least, if there is no actual reason for you to use it. If there is, there is no way to have the monospaceness of your snippet to look like in Xcode :).

Answer 2

What happens when you drop \usepackage{microtype}? It messes with kerning and so forth and might be the cause of the problem, which I assume is due to the poor alignment.
