"Intellisense" in emacs for clojure (inline docs & reminder drop-downs)?

Question

In this live-coding-in-clojure Overtone video demonstration , the author demonstrates emacs by flying through embedded documents and reminders. Within 54 seconds, he even emphasizes the fact, but leaves no significant hint on how to turn it on.

This is one thing with a flaw in my ideal emacs setup (I use nrepl and leiningen), and the only thing that draws me to other horrible mouse-oriented tools like Intellij and Eclipse. I am dying of the need for this institution!

I don’t know which melpa packages to install for installation, and I don’t know which smart single-word name I would name, so I don’t know how to look for it. "Intellisense for Clojure in Emacs" is as close as I could come to the search query, but it does not find anything useful.

Answer 1

It specifically uses the Overtone / emacs-live emacs setting, which contains the entire configuration for what you see in the video. The auto complete and doc lines appear to be provided by the ac-nrepl .

Answer 2

I think you are asking about autocomplete.el . Take a look and see if this is what you are talking about.
