after-save-file (augments, and augmentable only) in mode:host-text-mixin

Called just after the editor is saved to a file.

The argument to the method originally specified whether the save was successful, but failures now trigger exceptions such that the method is not even called. Consequently, the argument is always #t.

See also can-save-file? and on-save-file.

  If a surrogate is set, calls the surrogate with the arguments it was passed, plus this and a function that calls the super method.

  if a surrogate is not set, calls the super method and returns that result.
