"ERROR" messages containing "stderr" only indicate that the log was sent to
  stderr. Many servers send harmless messages via stderr.

    Gets the current log level.

    Return: ~
        (`integer`) current log level

set_format_func({handle})                      *vim.lsp.log.set_format_func()*

    Parameters: ~
      • {handle}  (`fun(level:string, ...): string?`) Function to apply to log
                  entries. The default will log the level, date, source and
                  line number of the caller, followed by the arguments.

    Return a function that can be passed to the `cmd` field for
    |vim.lsp.start()|.

    Parameters: ~
      • {host_or_path}  (`string`) host to connect to or path to a pipe/domain
                        socket
