emacs-cider 0.23.0 Clojure development environment for Emacs

CIDER (Clojure Interactive Development Environment that Rocks) aims to provide an interactive development experience similar to the one you'd get when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with Geiser) and Smalltalk.

CIDER is the successor to the now deprecated combination of using SLIME + swank-clojure for Clojure development.

There are plenty of differences between CIDER and SLIME, but the core ideas are pretty much the same (and SLIME served as the principle inspiration for CIDER).
