Psquair - The Pair Programming App of the Century

An Flask application that facilitates pair programming in conjuction with the Firepad JavaScript Library

Getting Started

These instructions should help you run the code on your machine.

Prerequisites

The code is written in Python3.

Libraries Used

• Flask
• Firepad
• Firebase
• PythonJWT
• PyCrypto

Installing

Clone the repository from GitHub:

$ git clone https://github.com/wcyn/bc-14-pair-programming

Change Directory into the project folder

$ cd bc-14-pair-programming

Install the dependencies from requirements.txt

$ pip install -r requirements.txt

Running the program

Export the run module that flask should use to run:

$ export FLASK_APP=run.py

Run the Flask application by typing:

$ flask run

export FLASK_APP=run.py

Resources Used

• Scotch.io Tutorial - (Getting Started with Flask, a Python Framework)[https://scotch.io/tutorials/getting-started-with-flask-a-python-microframework]

Running on c9.io (Cloud 9)

If running on c9.io. Use this as the run command in the run.py file so flask can run on the c9 directory. Remeber to import os, the in-buil;t Python os module.

app.run(host=os.getenv('IP', '0.0.0.0'),port=int(os.getenv('PORT', 8080)))

NOTES

You may find these helpful when setting up firebase authentication

Generating a public key from Firebase private key

• First, install (M2Crypto)[https://pypi.python.org/pypi/M2Crypto] (A Python crypto and SSL toolkit)

$ sudo apt-get install python-m2crypto

Then run the following code using Python2

# pb_key.py

from M2Crypto import RSA
RSA.load_key('path/to/server_key.pem').save_pub_key('path/to/server_key.pub')

Generating SSH public key from .pub RSA Public Key format

From the command line, run:

ssh-keygen -f my_public_key.pub -i -m PKCS8

This will output a public key in the the ssh-rsa format, which you can then store as an environment variable
