AskConfirm

AskConfirm["key"]

is a construct for use inside AskFunction that asks for confirmation of the current value associated with "key" and allows this to be either confirmed or changed.

AskConfirm["key",fun]

applies the function fun to determine how to ask for confirmation.

AskConfirm["key","str"]

applies the string "str" as a string template to ask for confirmation.

Details

  • AskConfirm returns the value associated with "key" when confirmation was accepted.
  • If confirmation is not accepted, AskConfirm["key"] effectively rewinds evaluation inside an AskFunction back to the previous time a value for "key" was requested.
  • In the context of the second argument of AskConfirm, the StringTemplate is applied with the association <|"key"->key, "value"->value|>.
  • AskConfirm["key"] is typically equivalent to AskConfirm["key","The current value of key `key` is `value`. Do you want to change it?"].
