LaTeX source code listing like in professional books

Question

How should a latex source code listing look like to produce an output like in known books  for example one for the Spring Framework  I ve tried with the latex listings package but wasn t able to produce something that looked as nice as the one below  So I m primarely interested in the formatting instructions to produce something like the sample below  from Manning s sample chapter for Spring in Action      EDIT With the help especially of Tormod Fjeldsk  r here s the complete snippet to produce the desired look    usepackage listings   usepackage courier   lstset      basicstyle  footnotesize ttfamily    Default font       numbers left                 Location of line numbers     numberstyle  tiny             Style of line numbers       stepnumber 2                 Margin between line numbers     numbersep 5pt                 Margin between line numbers and text     tabsize 2                     Size of tabs     extendedchars true      breaklines true               Lines will be wrapped     keywordstyle  color red       frame b        keywordstyle  1  textbf        keywordstyle  2  textbf        keywordstyle  3  textbf        keywordstyle  4  textbf     sqrt  sqrt        stringstyle  color white  ttfamily    Color of strings     showspaces false      showtabs false      xleftmargin 17pt      framexleftmargin 17pt      framexrightmargin 5pt      framexbottommargin 4pt        backgroundcolor  color lightgray       showstringspaces false    lstloadlanguages    Check documentation for further languages             Visual Basic         Pascal         C         C           XML         HTML       Java      DeclareCaptionFont blue   color blue        captionsetup lstlisting  singlelinecheck false  labelfont  blue   textfont  blue    usepackage caption   DeclareCaptionFont white   color white    DeclareCaptionFormat listing   colorbox cmyk  0 43  0 35  0 35 0 01   parbox  textwidth   hspace 15pt  1 2 3     captionsetup lstlisting  format listing labelfont white textfont white  singlelinecheck false  margin 0pt  font  bf footnotesize     Use it with this in your document    lstinputlisting label samplecode  caption A sample  sourceCode HelloWorld java

And please  whatever you do  configure the listings package to use fixed-width font  as in your example  you ll find the option in the documentation   Default setting uses proportional font typeset on a grid  which is  IMHO  incredibly ugly and unreadable  as can be seen from the other answers with pictures  I am personally very irritated when I must read some code typeset in a proportional font   Try setting fixed-width font with this    lstset basicstyle  ttfamily

It seems to me that what you really want  is to customize the look of the captions  This is most easily done using the caption package  For instructions how to use this package  see the manual  PDF   You would probably need to create your own custom caption format  as described in chapter 4 in the manual   Edit  Tested with MikTex    documentclass report    usepackage color   usepackage xcolor   usepackage listings    usepackage caption   DeclareCaptionFont white   color white    DeclareCaptionFormat listing   colorbox gray   parbox  textwidth   1 2 3     captionsetup lstlisting  format listing labelfont white textfont white     This concludes the preamble   begin document    begin lstlisting  label some-code caption Some Code  public void here         goes   the   code      end lstlisting    end document    Result

Have a try on the listings package  Here is an example of what I used some time ago to have a coloured Java listing    usepackage listings           lstset language Java captionpos b tabsize 3 frame lines keywordstyle  color blue  commentstyle  color darkgreen  stringstyle  color red  numbers left numberstyle  tiny numbersep 5pt breaklines true showstringspaces false basicstyle  footnotesize emph  label            begin lstlisting  public void here         goes   the   code              end lstlisting    You may want to customize that  There are several references of the listings package  Just google them

There are several other things you can do  such as selecting new fonts     documentclass 10pt a4paper  article        lots of packages e g  babel  microtype  fontenc  inputenc  amp c   usepackage color       Leave this out if you care about B W printing  obviously   usepackage upquote     Turns curly quotes in verbatim text into straight quotes                           People who have to copy paste code from the PDF output                          will love you for this  Or perhaps more accurately                           They will not hate you hate you less   usepackage beramono    Or some other package that provides a fixed width font  q v                          http   www tug dk FontCatalogue typewriterfonts html  usepackage listings    lstset                     A rudimentary config that shows off some features      language Java      basicstyle  ttfamily    Without beramono  we d get cmtt  the teletype font      commentstyle  textit    cmtt doesn t do italics  It might do slanted text though       keywordstyle           Nor does cmtt do bold text           color blue  bfseries       tabsize 4              Or whatever you use in your editor  I suppose     begin document    begin lstlisting  public final int ourAnswer     return 42     Our final answer       end lstlisting    end document

I wonder why nobody mentioned the Minted package  It has far better syntax highlighting than the LaTeX listing package  It uses Pygments     pip install Pygments   Example in LaTeX    documentclass article   usepackage utf8  inputenc   usepackage english  babel    usepackage minted    begin document   begin minted  python  import numpy as np  def incmatrix genl1 genl2       m   len genl1      n   len genl2      M   None  to become the incidence matrix     VT   np zeros  n m 1   int    dummy variable       compute the bitwise xor matrix     M1   bitxormatrix genl1      M2   np triu bitxormatrix genl2  1        for i in range m-1           for j in range i 1  m                r c    np where M2    M1 i j               for k in range len r                    VT  i  n   r k     1                  VT  i  n   c k     1                  VT  j  n   r k     1                  VT  j  n   c k     1                   if M is None                      M   np copy VT                  else                      M   np concatenate  M  VT   1                   VT   np zeros  n m 1   int       return M  end minted   end document    Which results in     You need to use the flag -shell-escape with the pdflatex command   For more information  https   www sharelatex com learn Code Highlighting with minted
