Specification

LanguageServer.jl is currently tracking version 3.0 of the protocol.

Server Capabilities

• Hover provider (textDocument/hover)
• Completion provider (textDocument/completion)
• Signature help provider (textDocument/signatureHelp)
• Definition provider (textDocument/definition)
• References provider (textDocument/references)
• Document highlight provider
• Document symbol provider (textDocument/documentSymbol)
• Workspace symbol provider (workspace/symbol)
• Code action provider (textDocument/codeAction) (this expects a client side registered function language-julia.applytextedit that can apply a vector of WorkspaceEdits to the client side documents).
• CodeLens
• Document formatting provider (textDocument/formatting)
• Document range formatting provider
• Document on type formatting provider
• Rename provider

Along with these standardised features the server sends/receives requests for:

• {"jsonrpc":"2.0","id":24,"method":"julia/reload-modules","params":null} : reloads imported modules.
• {"jsonrpc":"2.0","id":30,"method":"julia/lint-package","params":null} : runs special package linting.
• The server sends {"method":"window/setStatusBusy","jsonrpc":"2.0"} before handling a request and {"method":"window/setStatusReady","jsonrpc":"2.0"} when finished to allow the client to display a 'busy' indicator.
