Notifier functions

These functions can be used to supply an alert to the user that the evaluation of an expression succeeded or resulted in an error.

Usage

ft_beep_success_error(expr, success = 4, error = 2)

ft_ntfy_success_error(
  expr,
  success = "It Worked!",
  error = "Better Check on Me."
)

ft_notify_success_error(
  expr,
  success = "All done!",
  error = "Shit!",
  image = NULL
)

Arguments

expr

the expression to evaluate

success

what to use for success (sound or string)

error

what to use for an error (sound or string)

image

for notify, is there a specific image to use for the graphical notification?

Value

results of expression

Details

Each of these functions takes an expression as the first argument, so it is possible to pipe into them, or just wrap the expression to run. They check if the evaluated expression returns an error or not, so they can give the correct feedback to the user.

Examples

if (require(beepr)) {
  # usual syntax, works
  ft_beep_success_error(Sys.sleep(2))

  # have an error (can't add a letter to a number)
  ft_beep_success_error(2 + "x")

  # pipe syntax
  Sys.sleep(2) |> ft_beep_success_error()
}
#> Loading required package: beepr
#> Warning: there is no package called ‘beepr’
