-;;; Commentary:
-
-;;; support for evaluating clojure code, relies on slime for all eval
-
-;;; Requirements:
-
-;;; - clojure (at least 1.2.0)
-;;; - clojure-mode
-;;; - slime
-;;; - swank-clojure
-
-;;; By far, the best way to install these components is by following
-;;; the directions as set out by Phil Hagelberg (Technomancy) on the
-;;; web page: http://technomancy.us/126
-
-;;; Code:
-(require 'ob)
-
-(declare-function slime-eval "ext:slime" (sexp &optional package))
-
-(add-to-list 'org-babel-tangle-lang-exts '("clojure" . "clj"))
-
-(defvar org-babel-default-header-args:clojure '())
-(defvar org-babel-header-arg-names:clojure '(package))
-
-(defun org-babel-expand-body:clojure (body params)
- "Expand BODY according to PARAMS, return the expanded body."
- (let* ((vars (mapcar #'cdr (org-babel-get-header params :var)))
- (result-params (cdr (assoc :result-params params)))
- (print-level nil) (print-length nil)
- (body (org-babel-trim
- (if (> (length vars) 0)
- (concat "(let ["
- (mapconcat
- (lambda (var)
- (format "%S (quote %S)" (car var) (cdr var)))
- vars "\n ")
- "]\n" body ")")
- body))))
- (if (or (member "code" result-params)
- (member "pp" result-params))
- (format (concat "(let [org-mode-print-catcher (java.io.StringWriter.)]"
- "(clojure.pprint/with-pprint-dispatch %s-dispatch"
- "(clojure.pprint/pprint %s org-mode-print-catcher)"
- "(str org-mode-print-catcher)))")
- (if (member "code" result-params) "code" "simple") body)
- body)))
-
-(defun org-babel-execute:clojure (body params)
- "Execute a block of Clojure code with Babel."
- (require 'slime) (require 'swank-clojure)
- (with-temp-buffer
- (insert (org-babel-expand-body:clojure body params))
- (read
- (slime-eval
- `(swank:interactive-eval-region
- ,(buffer-substring-no-properties (point-min) (point-max)))
- (cdr (assoc :package params))))))
-
-(provide 'ob-clojure)
