Installation <span class="emoji">🖥️</span>

@content
`Minted`, another LaTeX package, is very useful to display source code. It requires the Python programming language.

As soon as **[Python is installed](https://www.python.org/)**, we can download the corresponding Python package **[`Pygments`](http://pygments.org/)** using a command prompt:

``` {.lang-sh .hljs}
pip install Pygments
```

Add the LaTeX package and we are good to go:

``` {.lang-tex .hljs}
\usepackage{minted}
```

@title
Compiler settings

@content
<div class="box warning">
  We need to pass the additional flag `--shell-escape` to our compiler in order to use `minted`.
</div>

In TeXstudio, go to **`Options → Configure TeXstudio → Commands`** and add the flag in the PdfLaTeX row before `%.tex`:

<code>pdflatex -syntex=1 -interaction=nonstopmode **\-\-shell-escape** %.tex</code>

Listings within LaTeX documents

++ Within a dedicated environment:

``` {.lang-tex .hljs .fragment}
\section*{Haskell Magic}
Squares of all even % …
\begin{minted}{haskell}
[x^2 | x <- [1..200], even x]
\end{minted}
```

++ Directly inline:

``` {.lang-tex .hljs .fragment}
\section*{An HTML Example}
A headline is denoted the following way:
\mint{html}|<h2>LaTeX at University</h2>|
```

External source code

@content
We can avoid redundancy by including source code directly from its source file.

``` {.lang-tex .hljs}
\section*{Simple Java Application}
\inputminted{java}{Test.java}
```

``` {.lang-java .hljs data-sourcefile="Test.java"}
public class HelloWorld {
    public static void main(/*…*/) {
        System.out.println(/*…*/);
    }
}
```

Configuring `minted`

@content
Optional parameters allow us to activate line numbers, automated line breaks, and syntax highlighting based on numerous color schemes.

``` {.lang-tex .hljs}
\usemintedstyle{monokai}
\begin{minted}[
linenos=true,
breaklines=true,
]{javascript}
    % ...
\end{minted}
```

Listing source code

@content
* Section 2.4 contains two **listings** that are currently commented out.
* ++ Include the **`minted` package** in the right place.
* ++ Make use of the **`minted` environment** to activate syntax highlighting for the first listing.
* ++ Move the second listing to a **new file** and include it using `\inputminted`.
* ++ Change the **color scheme** to `borland`.
