Functionality to do with initializing and shutting down the server ("General Messages" section of LSP spec).

structure Lean.Lsp.ClientInfo : Type

• name : String
• version? : Option String

def Lean.Lsp.instToJsonClientInfo.toJson : ClientInfo → Json

Equations

• Lean.Lsp.instToJsonClientInfo.toJson x✝ = Lean.Json.mkObj [[("name", Lean.toJson x✝.name)], Lean.Json.opt "version" x✝.version?].flatten

instance Lean.Lsp.instToJsonClientInfo : ToJson ClientInfo

Equations

• Lean.Lsp.instFromJsonClientInfo = { fromJson? := Lean.Lsp.instFromJsonClientInfo.fromJson }

inductive Lean.Lsp.Trace : Type

A TraceValue represents the level of verbosity with which the server systematically reports its execution trace using $/logTrace notifications. reference

• off : Trace
• messages : Trace
• verbose : Trace

structure Lean.Lsp.InitializationOptions : Type

Lean-specific initialization options.

• editDelay? : Option Nat

  Time (in milliseconds) which must pass since latest edit until elaboration begins. Lower values may make editors feel faster at the cost of higher CPU usage. Defaults to 200ms.

• hasWidgets? : Option Bool

  Whether the client supports interactive widgets. When true, in order to improve performance the server may cease including information which can be retrieved interactively in some standard LSP messages. Defaults to false.
