An NLI-GO application of the blocks world, a replication of Terry Winograd's SHRDLU (1970).
This is not an implementation of the original LISP code. It's rebuilt from the ground up in the Go programming language.
The web-interface was built with Quasar and Three.js

You'll find that it doesn't work perfectly. It still makes many silly mistakes. Consider it as part of the charm of the application, as this form of AI is quite brittle, and making it robust is still a big challenge. Research in the area of rule based AI has almost stopped completely about 20 years ago. I think this is unfortunate because it still has potential, and it's a great way to learn about semantics.

Install yarn version 1
Install the dependencies
yarn
Start the app in development mode (hot-code reloading, error reporting, etc.)
yarn quasar dev
Build the app for production
yarn quasar build
In quasar.config.js publicPath is set to /blocks as this is where the site is currently deployed. You may need to change it. There are also references in public/manifest.json.
On the server we have Apache 2.4. To enable websockets, enable these modules:
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod proxy_wstunnel
and add this simple line to the virtual host (on port 443):
ProxyPass /ws_chat ws://127.0.0.1:3333/
It proxies the request /ws_chat to port 3333
