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}
```

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 -synctex=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
* In the directory `exercises/source-code-listings` you can find a file named `Source.java`, which we want to include in our document.
* ++ **Include** the java code in the file `task-1.tex`. (Keep in mind that the file path is relative to the main LaTeX document, i.&thinsp;e., to `main.tex`.)
* ++ **Number** the code lines.
* ++ Use the **theme** `native`.
* ++ Change the **background colour** to dark blue. 
* ++ Now only include **lines 5 to 7**.
* ++ Delete the **spaces** at the beginning of the lines by using a suitable option (Hint: The documentation speaks of `gobble`).
* ++ If you have questions, try to consult the documentation of the Minted package.
