PythonBuddy 🖊️ 🐍

Online Python 2.7 Programming with Live Pylint Syntax Checking (Restricted version)

###Usage

1. Fetch from repo:

git clone https://github.com/ethanchewy/PythonBuddy.git

2. Change to directory

cd OnlinePythonLinterSyntaxChecker

2. Create virtualenv based on your own system:

virtualenv -p /usr/bin/python2.7 venv

3. Activate vitrual environment:

source venv/bin/activate

4. Pipe requirements to venv folder:

pip install -r requirements.txt

5. Set FLASK_APP variable:

export FLASK_APP = app.py

6. Run flask app:

flask run

Open your browser to localhost:5000 . Voila! 🎉 ###Current Features: Live Syntax Checking

Live Syntax Checking

• Uses Pylint as checker (only prints out errors and warnings)
• Syntax Highlighting


Python 2.7 Execution

• Python 2.7 Complilation
• Basic Sandboxing


Live Error Table with Additional Help Suggestions


###Customizing Options

1. Edit app.py to change any pylint options (like showing/hiding hints warnings)
2. Want Python 3?
3. Change step 2 from the installation instructions to:

   virtualenv --python=/usr/bin/python3.2 venv
   

4. Follow rest of instructions
5. To create a more secure Python Environment, check out the branch: https://github.com/ethanchewy/OnlinePythonLinterSyntaxChecker/tree/restrictedpython

###Future Goals:

• Make easily embeddable for MOOCs like edX and other education platform
• Stricter Python Sandboxing via Pypy's sandboxing solution
• Lower CPU usage
• Allow users to generate a link to a unique code snippet similar to JSBin

###FAQ: Why did you make this?
I made this so that MOOCs like edX or codecademy could easily embed and use this on their courses so students wouldn't have to go through the frustrations of setting up a Python environment and jump right into Python programming. Also, professors and teachers could easily set up a server and allow students to quickly test out their code with PythonBuddy online.

Has anyone created anything like this before?
There has never been a live syntax checker for python online. Similar projects that are not "live" are http://pep8online.com/ and http://antares.sip.ucm.es/cesar/pylint/

Has can I contribute?
You can 🌟 star my repo, fork my repo, submit a pull request, and/or open issues!

Where's the code for embedding it in MOOCs?
I'm currently working on this over here (for edx specifically): https://github.com/ethanchewy/pybuddy2.0

I want the code to actually compile and run in a certain way? If you want to actually execute the python safely look at my XBlock code: https://github.com/ethanchewy/pybuddy2.0 . Remember to sandbox the code with RestrictedPython or something.

How do I run my own server? https://github.com/ethanchewy/OnlinePythonLinterSyntaxChecker/wiki
