I used to created a similar function extension called "ob-clojure-literate.el"
for ob-clojure.el.
One functionality is to save plotting result image to a header argument :dir
specified directory.
But it's a little complicated. Then later I found another solution through
*header argument evaluation*:
#+begin_src clojure :results file link :dir "data/images" :file
"ob-clojure-incanter-move.png" :var dir=(concat (file-name-directory
(buffer-file-name)) "data/images/")
(use '(incanter core io charts stats))
(import '(java.io File))
(def hist (histogram (sample-normal 1000)))
(save hist "ob-clojure-incanter-move.png")
(.renameTo (File. "ob-clojure-incanter-move.png") (File. (str dir
"ob-clojure-incanter-move.png")))
#+end_src
But this code has a disadvantage:
This solution breaks Literate Programming tangling concept by introduced
un-reimplemented variable ~dir~.
