@ericzinda , It may be very useful if you also provide an interface using websockets for Language_server, in addition to stdio and tcp/ip. It should be rather easy to add.
People that want to make a UI for an app and don’t want to have to deal with sandboxing will find this very useful since they could connect directly from the browser.
Thanks for the suggestion @swi!
Is the scenario you are imagining one where a developer is building the UI for a local application using a browser? I.e. the browser and SWI Prolog are running on the same machine?
I think either same machine or over the LAN on the safe side of the firewall.
A key benefit, or property, of web-socket is that its like a “blackboard” accessible to all clients simultaneously – it can also only be one – the one that is the dedicated backend application server.
