# gnunigma
[Basic information](#basic-information) | [Compatibility](#compatibility) | [Installation](#installation) | [Requirements](#requirements) | [Platform differences](#features-missing-in-the-ubuntu-version) | [FAQ](#faq) | [License](#license)
## Basic information
* Gnunigma simulates the *enigma encryption machine*, which was used by the Germans in 20th century.
* **Language of choice** - python
* **Graphical library** - tkinter/Tkinter
## How it looks
### On Windows
* Warning! This screenshot is old and some new GUI features were added in newer versions! (as you can see on the Ubuntu screenshot)
### On Ubuntu
----
## Compatibility
* Gnunigma was tested on Windows 10 and Ubuntu (16.04, 16.10, 17.04) and should be compatible
### Installation
1. Download the source
2. If you are on Ubuntu and don't have Tkinter installed on python 3, run this command
```bash
sudo apt-get install python3-tk
```
3. Run the ```runtime.py``` file with python 3
### Requirements
1. Python version 3.5 and newer (older python 3 versions might work as well but were not tested by me!)
* *tkinter* library is included on Windows by default but must be installed on Ubuntu
### Features missing in the Ubuntu version
1. **Sound** - gnunigma on Windows is using the *winsound* library, which is not available on linux
2. **Icons** - there were some issues with iconbitmaps on
3. **Styling** - The gui does not looks as good as on Windows (scaling, weird colors)

# How it works
* Gnunigma has come a long way since the start of its developement, I tried to make it as "modular" as possible, this means:
1. Objects derived from the BaseEnigma
# Project hierarchy
* Files that require further explanations are links to sections describing them in more detail.
* **gnunigma/**
* **enigma/**
* [components.py](#components)
* **historical_data.yaml** - Historical enigma data
* **icons/** - Icons used by the Windows version
* **sounds/** - Sounds played by the Windows version
* **.gitignore** - Ignores .pyc and .idea folder from pycharm

* [runtime.py](#runtime)
# Files
## components
* Enigma simulation classes (enigma machines, machine parts, additional devices)
## cfg_handler
* Used for loading raw data from YAML files
## config
* Global configuration (GUI settings, enigma settings saved by the user, unit test config)
## data_handler
* Handlers (for sound and configuration/data IO)
## gui
* All GUI classes (most of them represent a window, others some tkinter derived classes)
## runtime
* Launches the GUI version
# Accomplishments of gnunigma
* Gnunigma proved its historical accuracy by successfully deciphering original enigma messages
* Message examples were taken from [this site](http://wiki.franklinheath.co.uk/index.php/Enigma/Sample_Messages)
