Though it looks and acts like that, and can be used in such a way with no problem, in a sense, you've got it inside out. From the GNU Emacs homepage: At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. It's not an editor with a lispy config language, it's a Lispy interpreter that comes with an editor that can configure it via said Lisp. It's kinda like one of those Smalltalk VMs where the line is blurred between the code you're writing and the environment that it runs in.
