I recently tried to set up J as described in
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-J.html, starting by loading j-mode from stable melpa, but I get an org-babel error output when I try to execute a J source code block: "/bin/bash: jconsole: command not found".
That makes it sound as if orgmode requires something besides setting j-console-cmd, which I had done:
-console-cmd is a variable defined in ‘j-console.el’.
Its value is "ijconsole"
Original value was "jconsole"
Documentation:
Name of the executable used for the J REPL session
You can customize this variable.
Looking at ob-J.el, I see
(defcustom org-babel-J-command "jconsole"
"Command to call J."
:group 'org-babel
:version "26.1"
:package-version '(Org . "9.0")
:type 'string)
and
(defun org-babel-J-eval-string (str)
"Sends STR to the `j-console-cmd' session and executes it."
(let ((session (j-console-ensure-session)))
(with-current-buffer (process-buffer session)
(goto-char (point-max))
(insert (format "\n%s\n" str))
(let ((beg (point)))
(comint-send-input)
(sit-for .1)
(buffer-substring-no-properties
beg (point-max))))))
Tips?
Thanks,
Bill
