Re: [O] [UPDATE] Re: ob-clojure evaluate error when Org-mode buffer has ns clojure code

[address@hidden]

Finally found a solution. really hard. spend a lot of time on this issue. The discussion is at here: https://github.com/clojure-emacs/clojure-mode/pull/465 Here is my final source code. paste here as a copy. Hope can help someone want same thing.

;; auto start CIDER REPL session in a complete Leiningen project environment for Org-mode Babel by jack-in.
(add-to-list 'org-babel-default-header-args:clojure
             '(:session . "*cider-repl ob-clojure*"))
(progn
  (find-file (expand-file-name "~/.emacs.d/Org-mode/ob-clojure/src/ob_clojure/core.clj"))
  (cider-jack-in))

(defun ob-clojure-cider-do-not-find-ns ()
  "Fix the issue that `cider-current-ns' try to invoke `clojure-find-ns' to extract ns from buffer."
  (with-current-buffer "*cider-repl ob-clojure*"
    (defvar ob-clojure-cider-repl-ns cider-buffer-ns)
    (setq-local cider-buffer-ns ob-clojuure-cider-repl-ns)))
(add-hook 'org-mode-hook #'ob-clojure-cider-do-not-find-ns)

I got new update on this issue.

I think it is caused by `(clojure-find-ns)`.
Here is my found:

I created a simple clojure project for used by all org-babel-clojure src blocks.
```elisp
(progn
  (find-file (expand-file-name "~/.emacs.d/Org-mode/ob-clojure/src/ob_clojure/core.clj"))
  (cider-jack-in))
```

I edebug the `org-babel-execute:clojure` process,

`org-babel-execute:clojure' has a step: ~(clojure-find-ns)~ .
This is from ~clojure-mode~. It will find current clojure buffer possible clojure namespace (even in org-mode). When I the following example org-mode buffer, it will return "namespace-not-found" error in nrepl response dict. Then src blcok has no error, not results.

```org
#+BEGIN_SRC clojure :session
(in-ns 'user-kk)
or
(ns user-kk)
#+END_SRC

#+BEGIN_SRC clojure :results output
(print "hi")
#+END_SRC
```

Here is a part of function `clojure-find-ns`:

      #+begin_src emacs-lisp
      (when (or (re-search-backward clojure-namespace-name-regex nil t)
                ;; Or any form at all.
                (and (goto-char (point-min))
                     (re-search-forward clojure-namespace-name-regex nil t)))
        (match-string-no-properties 4))
      #+end_src

So I created an PR to disable find namespace in Org-mode buffer:
