#' Shiny app for defining dm objects
#'
#' @description
#' `r lifecycle::badge("experimental")`
#'
#' This function starts a Shiny application that allows to define `dm` objects
#' from a database or from local data frames.
#' The application generates R code that can be inserted or copy-pasted
#' into an R script or function.
#'
#' @details
#' In a future release, the app will also allow composing `dm` objects directly
#' from database connections or data frames.
#'
#' The signature of this function is subject to change without notice.
#' This should not pose too many problems, because it will usually be run
#' interactively.
#'
#' @inheritParams rlang::args_dots_empty
#' @param dm An initial dm object, currently required.
#' @param select_tables Show selectize input to select tables?
#' @param debug Set to `TRUE` to simplify debugging of the app.
#'
#' @export
#' @examples
#' \dontrun{
#' dm <- dm_nycflights13(cycle = TRUE)
#' dm_gui(dm = dm)
#' }
