  • Any idea how one would do it for non-file buffers? I seem to recall seeing a S.O. thread a long while back that said it couldn't be done, but I could easily be misremembering. Commented Apr 1, 2015 at 18:16

    @Dan: AFAIK, there is no single function that all buffer-creation goes through. But you can try advising get-buffer-create. That's written in C, however. You can certainly advise generate-new-buffer, which calls get-buffer-create. (But you might also ask yourself whether you really need this for non-file buffers.) Commented Apr 1, 2015 at 18:25
  • Yes, I am familiar I read through the source and couldn't figure it out. I never heard of advise before so I will take a look at what that means. I think this solves it. Thanks! Commented Apr 1, 2015 at 18:31
  • advice-add is the new way to advise. But you can still use defadvice (which is good). Commented Apr 1, 2015 at 18:37
