This directory stores a small web app that runs on heroku that when posted to will return the AST of the posted code.

You can start it locally with:

bundle install
bundle exec rackup

This will start a local server on http://localhost:9292. You can then test it out by hitting it with curl, as in:

curl -X POST -d 'foo' http://localhost:9292

You can use the deployed version on heroku with the same curl command as above, but using the heroku URL, as in:

curl -X POST -d 'foo' https://prettier-ruby.herokuapp.com

To deploy this app to heroku, use the playground/deploy bash script. Basically it just git pushs to heroku using the playground subtree, provided the playground/ripper.rb file is synced up with the one from src/ripper.rb.
