#' Globally define handling of empty else conditions in JS
#'
#' Some JS functions allow to decide whether empty \code{else} statements should be omitted or printed
#' nonetheless (which some consider more reader friendly). The default can be globally defined with
#' \code{rk.set.empty.e}, so you don't have to specify it in each function call.
#'
#' \code{rk.get.empty.e} returns the set value, which defaults to \code{FALSE} by default.
#'
#' @param empty Logical, whether .
#' @return \code{rk.set.empty.e} returns invisible(NULL), \code{rk.get.empty.e} either \code{TRUE} or \code{FALSE}.
#' @rdname rk.set.empty.e
#' @export
rk.set.empty.e <- function(empty=FALSE){
set.rk.env("empty.e", value=empty)
return(invisible(NULL))
}
