Emacs an editor of a lifetime

Emacs is one of the oldest and weirdest programs I use, but I just recently started to appricate it more and more. I gave it a try when I was writing my master thesis, but I had no idea what I was doing. (not to say that I understand it now, completly, just more, just enough). I stumbled on this editor when I was planning on learning Elixer, and looked on the internet for an IDE for this.
