Completion proposals sorted client side.

[ylussaud]

I was wondering why the LSContentAssistProcessor is sorting completion proposals from the server ?

Is there a way to keep the server completion proposal order ?

What does the LSP spec mention about that? IIRC some LSs clearly don't sort anything and leave it to the IDE to go for sorting heuristic (Based on similarity or other deduced data). Maybe there is a capability to clarify what strategy to use?

The LSP spec is pretty detailed about this. It is something along the lines of:

• in general, the client is responsible for sorting and even filtering the results from the language server(s)
• the language server can add additional hints/information to the completion proposals to advise the client what to do (how to sort and filter).

This section describes this in more detail: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_completion

And I think LSP4E follows this logic (at least to a certain degree).

Thank you for your replies, I'll check the documentation to try to keep the semantic order or my language client side.
