front end - Automatically execute command after save

I want to run some code automatically after saving my notebook. Is there a $ variable or setting for this?

Answer

Yes, it can be easily implemented with FrontEndExecute, e.g.:

SetOptions[EvaluationNotebook[], NotebookEventActions -> 

  {{"MenuCommand", "Save"} :> Print["HEY"], PassEventsDown -> True}];

You can insert any code instead of Print command

---

Edit

Above code executes Print["HEY"] before saving the notebook, because you catch the event at the beginning, do some work and release it back to program with PassEventsDown.

To evaluate some code after saving - one has to handle full event manually. The simplest would be just remove PassEventsDown and instead of Print["HEY"] write (NotebookSave[]; Print[123]):

SetOptions[EvaluationNotebook[], NotebookEventActions ->
    {{"MenuCommand", "Save"} :> (NotebookSave[]; Print[123])}]

Unfortunately, this will "intercept" also saving event triggered by "Save As" command and it will always save file with its old name even if we change name in "Save As" window.
