Language Server Protocol for Prolog

[erlanger]

It would be great to implement an LSP server (language server protocol) for Prolog, so that we would have code completion, compilation errors, etc support in many editors, something like this:

but for prolog.

I think someone already did a lot of the work writing a Vscode server for SWI-Prolog (which is essentially an LSP server).

It would probably be a good idea to use that code to setup a standalone LSP server that would work with any editor. Almost all languages have support today, I would not like for Prolog to be left behind.

Update: I think most of the backend code needed for this is already in SWISH, it would just need to be tailored to LSP.

Seems there is an implementation already: https://github.com/jamesnvc/lsp_server/
But it would be awesome to have it in SWIPL out of the box.

Yes, I tried it, but it doesn't work with neovim's LanguageClient.

@erlanger what exactly doesn't work? Maybe it makes sense to open bug in one project or another?

For example I requested the support for it in Ale: dense-analysis/ale#2657
