First steps with LATEX
@content
In order to compile the script for this tutorial, a few steps have to be followed, which are explained in the next slides.

@title
Digression: Opening a command prompt
@content
* For the following tasks, we are going to need a command prompt
* It can be opened in different ways, depending on your operating system
* **Windows**: Press the Windows key and type in *cmd*, press Enter
* **MacOS**: Press the *Command* key and the *space bar* simultaneously, then type in *Terminal* and double click on *Terminal*
* **Linux**: Press ``Ctrl + Alt + T``

Installing the compiler
@content
* The compiler translates our LATEX code into a PDF
* Depending on your operating system, different compilers are available
* Windows: MikTEX
* macOS: MacTEX
* Linux distributions: TEXLive
* Debian-based distributions: run `sudo apt install texlive-full`
* other distributions: see the TEXLive website
Make sure to install the full version with all packages, if you can!

Installing the editor
@content
* An editor can downloaded once the compiler has been installed
* For editing LaTeX documents, any text editor works fine, e.g., Notepad++, VSCode
* For beginners, TEXstudio is recommended due to its LaTeX-specific features
* Download and install TEXstudio

Compile the script for the first time
@content
* Download the project archive from the VC.
* Unzip the archive.
* Open the file `main.tex` in TEXstudio. It is located in the root directory of the archive.
* Compile `main.tex` by pressing ⏩
* A few new files will be generated by the compilation.
Windows users: In order to enable file endings, click the view tab in the file explorer, and select *file name extensions*. This helps differentiating the different ``main`` files.

Listings
@content
We have multiple examples of LaTeX source code in the script. As a default setting, we use the package **listings** for displaying them.
* However, the package **minted** generates more appealing listings.
* Minted requires additional configuration, like the installation of the programming language **Python 3** and the package **Pygments**
* The following slides explain how to use `minted` for this LaTeX project

@title
Installation of Python 3
@content
* Check if Python is already installed on your operating system using a command prompt:
``` {.lang-sh .hljs}
python --version
```
* If installed, the output should look similar to this (the exact version may deviate):
``` {.lang-sh .hljs}
Python 3.10.6
```
* If not installed, follow the instructions for your operating sytem on the **[website](https://www.python.org/)**.
* Make sure to enable the option to add Python to your PATH, if possible.
* Run the above-mentioned command to ensure the installation was successful.

`Pygments` and compiler command settings
@content
* Install the **Pygments** by executing the following command in a command prompt:
pip install Pygments
* In TeXstudio, navigate to Options → Configure TeXstudio → Commands
* Next to the PdfLaTeX label, add the ``shell-escape`` flag to the compiler command:
pdflatex -synctex=1 -interaction=nonstopmode **\-\-shell-escape** %.tex
Passing the flag ``--shell-escape`` to your compiler can be a potential security risk. **Only do it for documents you trust!**

Change the listings mode
@content
In order to compile the script using `minted`, the listings mode has to be changed.
* Create a new file in the root directory of the project archive, named `listings-mode.tex`
* Insert the following command into the newly created file
``` {.lang-tex .tex .hljs}
\newcommand\listingsmode{minted}
```
* Compile `main.tex` again by pressing ⏩
