func (*Server) StartWork

func (s *Server) StartWork(ctx context.Context, title, message string, cancel func()) *WorkDone

StartWork creates a unique token and issues a $/progress notification to begin a unit of work on the server. The returned WorkDone handle may be used to report incremental progress, and to report work completion. In particular, it is an error to call StartWork and not call End(...) on the returned WorkDone handle.

The progress item is considered cancellable if the given cancel func is non-nil.

Example:

func Generate(ctx) (err error) {
  ctx, cancel := context.WithCancel(ctx)
  defer cancel()
  work := s.StartWork(ctx, "generate", "running go generate", cancel)
  defer func() {
    if err != nil {
      work.End(ctx, fmt.Sprintf("generate failed: %v", err))
    } else {
      work.End(ctx, "done")
    }
  }()
  // Do the work...
}

func (*Server) Symbol

func (s *Server) Symbol(ctx context.Context, params *protocol.WorkspaceSymbolParams) ([]protocol.SymbolInformation, error)

func (*Server) WorkDoneProgressCancel

func (s *Server) WorkDoneProgressCancel(ctx context.Context, params *protocol.WorkDoneProgressCancelParams) error

type WorkDone

type WorkDone struct {
	// contains filtered or unexported fields
}

WorkDone represents a unit of work that is reported to the client via the progress API.

func (*WorkDone) End

func (wd *WorkDone) End(ctx context.Context, message string) error

End reports a workdone completion back to the client.

func (*WorkDone) Progress

func (wd *WorkDone) Progress(ctx context.Context, message string, percentage float64) error

Progress reports an update on WorkDone progress back to the client.
