[SWLS demo] Add prefix from the moment it’s written

[pietercolpaert]

I’m not sure what’s possible with LSPs, or whether this will be a limitation of it, but I’d like a prefix to be added from the moment it’s written

Demo from YASGUI

While in SWLS I’m not sure how to trigger it correctly:

I'll see what I can do, yes it should be possible to automatically autocomplete the prefixes, but I'm not entirely sure Monaco supports that.
It's actually pretty funny to integrate the LSP into monaco because all the requests have to be translate from monaco to lsp and the responses have to be translated back

@ajuvercr this has already been done in the Qlue-ls SPARQL language server built by the Qlever team (also written in rust): https://github.com/IoannisNezis/Qlue-ls

It is much more advanced in term of SPARQL features (not fully done though), it could be really nice to bridge the 2 (so you can focus on everything else that is not SPARQL, and pass the right info to the SPARQL LS when needed, e.g. ontology/shapes to help for autocompletion)
