# bahn-price-analyzer
Analyzing the prices of the Deutsche Bahn (based on project [juliuste/db-prices](https://github.com/juliuste/db-prices))

Small terminal application for the given API.

# Getting started
**You need: npm package manager and pip installer**

### Linux systems
0. `git clone git@github.com:frankzl/bahn-price-analyzer.git`
1. run `setup.sh`
2. enjoy! :)

This will setup aliases in your system, allowing you to use short commands:
- `bahn` to run the user program
- `bahn_info -f "Oldenburg (Oldb) Hbf" -t München Hbf -fd 2018-12-04 -td 2018-12-07` to query

Not sure if this works on macOS.. maybe someone can try it out

### Otherwise:
0. `git clone git@github.com:frankzl/bahn-price-analyzer.git` 
1. `npm install`
2. `pip install -r db_console/requirements.txt`
3. enjoy! :)

# Requirements
1. [numpy 1.15.2](https://pypi.org/project/numpy/) 
2. [colorama 0.3.9](https://github.com/tartley/colorama)
3. [pandas v0.23.4](https://pypi.org/project/pandas/)
4. [Naked v0.1.31](https://github.com/chrissimpkins/naked.git)
5. [readline](https://pypi.org/project/readline/)

# Example commands
At the moment you can only specify the place by giving the exact station name, which can be found inside `stations.csv`. (still in progress, maybe we'll fix it with fuzzy matching)

`python db_console/db_info.py -f "Oldenburg (Oldb) Hbf" -t "München Hbf" -fd 2018-12-15 -td 2018-12-24`

 will write data into file:

`data.csv`

# CSV file: data.csv
column names: date, hour, departure_time, arrival_time, stops, price, ticket_type, train_type

departure and arrival format:
'2017-06-05T08:53:00.000Z'
