Hello-

Has anyone used nrepl with org-babel Clojure?
I use org-babel and I would like to get it running with nrepl instead of slime/swank.

I was wondering if I could get some help modifying these functions to sub nrepl for slime/swank.
Any help would be much appreciated.

Hi Greg,

I took a quick look and was able to an eval from ob-clojure working, so it should be doable.

However there are a few things I need to get merged into master for you to be able to do it.

I will try to get that this evening, and then I can help you with the modifications.

Cheers,

Hi Greg,

Give this a go:

(declare-function nrepl-send-string-sync "ext:nrepl" (code &optional ns))

(defun org-babel-execute:clojure (body params)

  "Execute a block of Clojure code with Babel."

  (require 'nrepl)

  (with-temp-buffer

    (insert (org-babel-expand-body:clojure body params))

    ((lambda (result)

       (let ((result-params (cdr (assoc :result-params params))))

         (if (or (member "scalar" result-params)

                 (member "verbatim" result-params))

             result

           (condition-case nil (org-babel-script-escape result)

             (error result)))))

     (plist-get (nrepl-send-string-sync

                 (buffer-substring-no-properties (point-min) (point-max))

                 (cdr (assoc :package params)))

                :value))))

It worked for me with the latest code on master.  Let me know if that works for you.

Cheers,

Tim

First quick attempt returns:

Wrong type argument: stringp, nil

in the mini-buffer.
Need to double check my mods to ob-clojure.el.
I changed the name of the compiled elc file, and assume it will load the non-compiled version.

I will try it later today, and I'll post a simple test case if required.
I believe I have the latest and greatest, emacs 24.2, org 7.9, and nrepl 0.1.3 (org and nrepl via elpa).

Regards,
Greg

Hi Greg,

You will need the latest nrepl.el from github (0.1.4-preview).

And there are snapshot packages on Melpa (http://melpa.milkbox.net/).

I added Melpa to my list of package sources, and the nrepl 0.1.4-preview appeared in the list.
Downloaded and installed the new version of nrepl successfully.

org-babel Clojure is now working with nrepl-jack-in.  I did a quick test drive on a medium sized .org file with
several snippets of Clojure.  I'm using Clojure and Incanter to process some data and write LaTeX and pdf files.
I then export the org file as LaTeX and include the Clojure generated LaTeX files to generate a large document.

Upon initial inspection, everything was output the same as when using lein-swank.
I'll continue to test-drive the set-up and report back with any additional comments.  So far, so good!

Thank you very much for the help,
Greg
