#Toy interpreter for Brainf@@k



Example program for trying out driver.love, a programming environment for modifying programs live, without restarting them.

Some reference documentation on how to create your own apps.

This repo is an example of a Freewheeling App, designed above all to be easy to run, easy to modify and easy to share.

#Getting started

Install LÖVE. It's just a 5MB download, open-source and extremely well-behaved.

Run the app using LÖVE.


To modify it live without restarting the app each time, download the driver app.

If the app being modified by the driver lives in a .love file, your changes will go into the save directory. If it lives in a directory (like this repo), your changes will go straight into the same directory.

#Keyboard shortcuts
