Provides an IpcM monad for interacting with an external LSP process. Used for testing the Lean server.

partial def Lean.Lsp.Ipc.readResponseAs (expectedID : JsonRpc.RequestID) (α : Type) [FromJson α] : IpcM (JsonRpc.Response α)

Reads response, discarding notifications and server-to-client requests in between. This function is meant purely for testing where we use collectDiagnostics explicitly if we do care about such notifications.

def Lean.Lsp.Ipc.waitForExit : IpcM UInt32

def Lean.Lsp.Ipc.collectDiagnostics (waitForDiagnosticsId : JsonRpc.RequestID := 0) (target : DocumentUri) (version : Nat) : IpcM (Option (JsonRpc.Notification PublishDiagnosticsParams))

Waits for the worker to emit all diagnostic notifications for the current document version and returns the last notification, if any.

We used to return all notifications but with debouncing in the server, this would not be deterministic anymore as what messages are dropped depends on wall-clock timing.

partial def Lean.Lsp.Ipc.collectDiagnostics.loop (waitForDiagnosticsId : JsonRpc.RequestID := 0) : IpcM (Option (JsonRpc.Notification PublishDiagnosticsParams))

def Lean.Lsp.Ipc.waitForILeans (waitForILeansId : JsonRpc.RequestID := 0) (target : DocumentUri) (version : Nat) : IpcM Unit

def Lean.Lsp.Ipc.waitForMessage (msg : String) : IpcM Unit

Waits for a diagnostic notification with a specific message to be emitted. Discards all received messages, so should not be combined with collectDiagnostics.

partial def Lean.Lsp.Ipc.waitForMessage.loop (msg : String) : IpcM Unit

def Lean.Lsp.Ipc.runWith {α : Type} (lean : System.FilePath) (args : Array String := #[]) (test : IpcM α) : IO α
