Make R/RStudio beep play after *every* command

Question

My question relates to making R beep after a command. I understand that I can run beep() together with whatever command I want to run, but is there a way to automatically run beep() (from beepr package) or system("say done") (I run RStudio on a Mac) after every command?

e.g. is there a options() setting I can tweak so that after entering every command in the interpreter another command like beep() is executed?

Answer 1

You want addTaskCallback.

addTaskCallback(function(...) { system("say done"); TRUE }, name = "announce when done")

Have fun!
