Hi,
I'm working on adding async call functionality to org-babel blocks so I
don't need to block my main Emacs for long running calculations. However
I'm having problems with the insertion of the results once handled. My
code looks like this:
(defmacro async-org-call (async-form)
"Expands `ASYNC-FORM' as an asynchronus org-bable function.
If executed inside an org file will insert the results into the src
blocks results. Otherwise the result will be echoed to the Message
buffer."
(let ((result-buffer (buffer-name))
(result-org-name (nth 4 (org-babel-get-src-block-info))))
`(async-start
;; The result of the async-sexp is returned to the handler
;; as result.
(lambda ()
,(async-inject-variables "async-form")
(eval async-form))
;; This code runs in the current emacs process.
(lambda (result)
(let ((buf ,result-buffer)
(org ,result-org-name))
;; Send the results somewhere
(if (and buf org)
(save-excursion
(with-current-buffer buf
(org-babel-goto-named-result org)
(org-babel-insert-result (format "%s" result))))
(message (pp (format "async-result: %s" result)))))))))
However the insert result seems to keep skipping the named result I'm
aiming for (I was calling basic-async-test, the results end up after
async-with-delay in a fresh RESULTS: drawer):
** Basic async
#+name: basic-async-test
#+begin_src emacs-lisp
(async-org-call (format "this is in inferior"))
#+end_src
#+RESULTS: basic-async-test
: #<process emacs>
#+name: async-with-delay
#+begin_src emacs-lisp
(async-org-call ((sleep-for 3) (format "woken up")))
#+end_src
#+RESULTS:
=this is in inferior
=: this is in inferior
#+RESULTS: async-with-delay
: #<process emacs>
Any idea how I can do this better?

Ping? Is this something I should just write a custom routine for to
replace a token generated at the initial call?
