shell-command-sentinel hook?

[Christopher Howard <christopher@librehacker.com>]

Hi, I was just wondering if it would be difficult/problematic to patch simple.el to provide some kind of hook so that, when async shell commands complete, users can run arbitrary elisp? I imagine this would get inserted at the end of shell-command-sentinel...?

I've been getting in the habit lately of moving my activities out of Gnome console and instead running shell commands with async-shell-command. But something I miss is that Gnome console will send a notification at the end of the command which is very visible on the desktop. This can be reproduced in Emacs by adding " && notify-send \"some message\"" onto the end of the command. This works, and could be wrapped in various ways, but it would be nice if the exit code was passed on as well to the callback. I imagine other people would come up with various other creative uses of the hook, especially if we also passed in the command string to the callback.

Am running GNU Emacs 29.1.
