|
;; Support for evaluating clojure code
|
|
|
|
;; Requirements:
|
|
|
|
;; - clojure (at least 1.2.0)
|
|
;; - clojure-mode
|
|
;; - inf-clojure, cider or SLIME
|
|
|
|
;; For clojure-mode, see https://github.com/clojure-emacs/clojure-mode
|
|
;; For cider, see https://github.com/clojure-emacs/cider
|
|
;; For inf-clojure, see https://github.com/clojure-emacs/cider
|
|
|
|
;; For SLIME, the best way to install these components is by following
|
|
;; the directions as set out by Phil Hagelberg (Technomancy) on the
|
|
;; web page: https://technomancy.us/126
