Was ist eine gute Möglichkeit, sehr wenige Codezeilen einzufügen?

Question

Ich weiß über das listingsPaket Bescheid, aber es scheint, dass es nicht dort platziert werden kann, wo ich es haben möchte ( him Float).

Und da ich vielleicht nur genau eine Codezeile einfügen möchte, möchte ich, dass sie wirklich dort steht, wo ich sie eingefügt habe. Gibt es eine gute Möglichkeit?

Answer 1

Option 1: Verwenden Sie das listingsPaket

Einfache Konfiguration für LaTeX-Header (vorher \begin{document}):

\usepackage{listings}
\usepackage{color}

\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

\lstset{frame=tb,
   language=Java,
   aboveskip=3mm,
   belowskip=3mm,
   showstringspaces=false,
   columns=flexible,
   basicstyle={\small\ttfamily},
   numbers=none,
   numberstyle=\tiny\color{gray},
   keywordstyle=\color{blue},
   commentstyle=\color{dkgreen},
   stringstyle=\color{mauve},
   breaklines=true,
   breakatwhitespace=true
   tabsize=3
   }

Sie können die Standardsprache mit in der Mitte des Dokuments ändern \lstset{language=Java}.

Anwendungsbeispiel im Dokument:

\begin{lstlisting}
  // Hello.java
  import javax.swing.JApplet;
  import java.awt.Graphics;

  public class Hello extends JApplet 
  {
    public void paintComponent(Graphics g) {
      g.drawString("Hello, world!", 65, 95);
    }    
  }
\end{lstlisting}

Hier ist das Ergebnis:

Option 2: Nutzen Sie die verbatimUmgebung

Answer 2

Das numberedblockPaket ist für die Darstellung kurzer Codeblöcke gedacht. Aus dem Anwendungsbeispiel des Pakets:

\documentclass[10pt]{article}
\usepackage{numberedblock}

\begin{document}

\parindent 0.3in
%\setlength\maxblocklabelsize{-.4in}
\setlength\blockindent{0.0in}

This is a test of the \textsf{numberedblock} style packcage, which is
specially designed to produce sequentially numbered BLOCKS of code (note
the individual code lines are not numbered, but the whole block gets a
single number, for later reference (much in the same way that equations
can get numbered in a document).  While specialized for numbering code
blocks, the commands can actually number other items, as well, in fact
anything that fits in a \LaTeX{} box.

If the code block contains no special characters, one can simply use the
command form, called \verb,\numblock,.  It cannot handle verbatim text,
but must use standard \LaTeX{} escape sequences (for line breaks,
contiguous spaces, special characters, etc.).  It puts the output in a
tt font , which is the same used in the verbatim environment:

\numblock{This text is the\\argument to the command\\where double
slashes have been\\used for line breaks}

Most useful, however, there is also the \verb,numVblock, environment,
which handles verbatim text, as seen in the next example:

\begin{numVblock}
This is the numVblock 
environment, which         (<--see contiguous spaces here)
succeeds in
incorporating verbatim text like
@##$%*$%$()||}{?><\\    \end{numVblock}

As envisioned the \verb,numVblock, environment would be ideally suited
for displaying small code blocks as part of documentation.  The code can
contain contiguous spaces and special characters:

\begin{numVblock}
      program test
      implicit none
      integer a, x
c$$$$$$$$$$$$$$$$$$$$$$$$$
      a = 0
      x = 1
   10 a = a + x
      if (a .eq. 100) stop
      goto 10
      end
\end{numVblock}

Below, I test the \verb,\numblock, command with the argument as a
box, rather than as formatted text.

\numblock{\fbox{Testing, 1,2,3 testing a box}}

Don't forget, there are settable parameters to define the block
left-indent, the format of the label, and (if needed) the labels' max
width/placement.
