# Xquisite Branch
A branching version of the [exquisite corpse](https://en.wikipedia.org/wiki/Exquisite_corpse) game. A drawing app developed for [SI17](https://issue.xpub.nl/17/).
Draw something, upload it and send the link to someone else: they will continue from your drawing. But wait! There's a catch!!!!! If you send to just one person the chain will continue linearly, but send it to more people and things will start branching in different directions.
## Install
Clone the repository.
```
git clone https://git.xpub.nl/kamo/exquisite-branch.git
```
Create a virtual environment.
```
python3 -m venv venv
```
Install the requirements with `pip` and the `requirements.txt` file.
```
pip install -r requirements.txt
```
Create an `.env` file in the root folder of the project with the following variables:
```
DEBUG=True
FLASK_ENV=development
FLASK_APP=exquisite_branch
```
Before running the app for the first time, be sure to initialize the database. __Watch out:__ this will delete the previous instance of the database along with its contents!
```
flask init-db
```
After initializing the database you can run the flask application
```
flask run
```
## Overview
_Xquisite Branch_ saves contents in a database, and join them together in a branching version of the exquisite corpse.
The original exquisite corpse data structure is something similar to a linked list, where every drawing is connected to the previous one. Contents in _Xquisite Branch_ are saved in a database with the same principle.
Each entry in the database has the following properties:
- `id`: a unique identifier for every entry
- `branch`: a random name for the excerpt
- `parent`: the random name of the previous excerpt
- `content`: the actual content of the writings
- `username`: the author of the excerpt
When generating the display page, every entry look up its `parent` property to position itself after that.
Mhh should rewrite this better bc is super convoluted ahah.
