;;; Commentary:
;;; support for evaluating clojure code, relies on nrepl for eval
;;; Requirements:
;;; - clojure
;;; - clojure-mode
;;; - nrepl
;;; Best way to get clojure is with https://github.com/technomancy/leiningen
;;; Best way to get nrepl is from MELPA (clojure-mode is a dependency).
;;; Code:
(require 'ob)
(require 'ob-tangle)
(defvar org-babel-tangle-lang-exts)
(add-to-list 'org-babel-tangle-lang-exts '("clojure" . "clj"))
(defvar org-babel-default-header-args:clojure
'((:results . "value") (:tangle . "yes")))
(defun org-babel-execute:clojure (body params)
"Execute a block of Clojure code with Babel and nREPL."
(require 'nrepl)
(if (nrepl-current-connection-buffer)
(let* ((result (nrepl-eval body))
(s (plist-get result :stdout))
(r (plist-get result :value)))
(if s (concat s "\n" r) r))
(error "nREPL not connected! Use M-x nrepl-jack-in.")))
(provide 'ob-clojure-nrepl)
;;; ob-clojure-nrepl.el ends here
