Early WIP Currently authentication, document sync, completion requests/responses are functional. Editor context is forwarded to github copilot servers and completions are provided to the editor in response.
These results can be retrieved by requesting textDocument/getCompletionsCycling
You can use this language server by by checking out the copilot-rs branch on both copilot.lua and copilot-cmp. Please note that this is an early stage project, and bugs which break functionality are to be expected.
