# Machine Setup

## General

### Git

The whole project is a Git repository,
to do anything you'll need to have Git setup on your machine.

!!! tip
    We highly recommend you use Git directly typing commands to your terminal,
    instead of relying on any GUI tools, IDE integration's what-so-ever.
    They make life easy, sure.
    But do you know, what exact calls they do under the hood? If no, don't use them.

#### Installation

=== "*nix"
    Should be part of all major systems default software distribution path.

=== "Windows"
    !!! warning "disclaimer"
        This is for people having not much experience.
        If you e.g. use Cygwin, you could just install Git from there and ignore this^^

    - Download Git: [Git-SCM][gitscm-win]
    - Installation recommendations:
        - opt-out from `Enable Git Credential Manager`  
            _We had bad experiences with it, storing wrong passwords an no one knew where to remove them as none of the pros used this thing^^_

#### Configuration

After installing Git, you'll have to set a few information,
in order to be able to work with it.
Mandatory is your username and email.

Globally set your most used username and email address you'll be using.

```bash
git config --global user.name "<username>"
git config --global user.email "<email address>"
```

!!! attention
    If your global email is different from the one for this projects GitLab,
    make sure to either add your main email address as committer email in your profile,
    or change the git config for this project individually after cloning it.

## Java Development

The Java parts are development with OpenJDK 8 and Maven 3.6

### Requirements

- Git setup
- OpenJDK 1.8.0+ _(Java parts)_
- Maven 3.6.0+ _(Java parts)_

### Installation

#### OpenJDK

=== "*nix"
    Check your specific systems package names.

    __Ubuntu 20.04__:  
    ```bash
    sudo apt install openjdk-11-jdk
    ```

=== "Windows"

    - download OpenJDK: [jdk.java.net][java-net]
    - extract archive to permanent place
    - create/update system environment variable `JAVA_HOME`,
        to the path you extracted OpenJDK to.
    - update `PATH` variable including the `bin` folder of your newly placed OpenJDK
    - check with a terminal that `java --version` works

#### Maven

=== "*nix"
    Same as before, check your specific systems package names.

    __Ubuntu:__  
    ```bash
    sudo apt install maven
    ```

=== "Windows"

    - download Maven binary: [maven.apache.org][maven-dl]
    - extract archive to permanent place
    - create/update system environment variable `MAVEN_HOME`,
        to the path you extracted Maven to.
    - update `PATH` including `bin` folder of maven home
    - check that `mvn --version` works

## MkDocs (Documentation)

This project is documented using MkDocs Material.
It means we write Markdown files, organize them in a configuration file
and MkDocs generates a static Website out of it we host and you are reading right now.

### Requirements

- Python 3.5+
- pip
- Python virtual environment _(optional)_

### Installation

=== "*nix"
    check system specific names and commands, below are some examples collected over time:

    __Ubuntu:__  
    ```bash
    sudo apt install python3 python3-pip python3-venv
    ```

=== "Windows"
    - download & install Python: [python.org][python-win-dl] (use executable installer version)

- open a terminal inside the project's root directory
- _optional:_ create & activate new virtual environment:

    === "*unix"
        ```bash
        python3 -m venv env
        . ./env/bin/activate
        ```

    === "Windows"
        === "CMD"
            ```cmd
            python -m venv env
            env\scripts\activate.bat
            ```
        === "Power Shell"
            !!! attention "execution policy"
                You may have to first set the correct execution policy,
                before able to run the activation script.

                ```powershell
                Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
                ```

            ```powershell
            python -m venv env
            env\scripts\Activate.ps1
            ```

- install all required packages:  
    ```
    pip install -Ur requirements.txt
    ```

### Usage

To work on the documentation, the mkdocs development server has to run.
On start it tells you on which port it runs (default is `8000`).

Open the Browser on the shown URL and edit the Markdown files.
On saving changes your Browser should automatically reload the page.

- _optional:_ enter python virtual environment

    === "*unix"
        ```bash
        . ./env/bin/activate
        ```

    === "Windows"
        === "CMD"
            ```cmd
            env\scripts\activate.bat
            ```
        === "Power Shell"
            !!! attention "execution policy"
                You may have to first set the correct execution policy,
                before able to run the activation script.

                ```powershell
                Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
                ```

            ```powershell
            env\scripts\Activate.ps1
            ```

- start MkDocs development server:  
    ```bash
    mkdocs serve
    ```
- work
- kill dev server by pressing `ctrl+c`
- _optional:_ exit python virtual environment:  
    ```bash
    deactivate
    ```

### Editor/IDE

You don't need any special IDE, as a bare minimum a text editor would work (even vim is possible).  
__But don't you dare to use this crappy Microsoft built in editor!__

Practically it's very supportive of course,
to use a IDE that has good markdown support in terms of code-highlighting,
table formatting, etc.  
Below are collected tips for different IDE's.

=== "VSCode"
    recommended extensions:  
    _these are the extension id's searchable from vscode_

    - `editorconfig.editorconfig`
    - `waderyan.gitblame`
    - `yzhang.markdown-all-in-one`
    - `jebbs.plantuml`
