Subject: Re: [babel] using #+call for inline results

Hi,

The documentation for #+call is rather confusing:

  It is also possible to evaluate named code blocks from anywhere in
  an Org-mode buffer or an Org-mode table. #+call (or synonymously
  #+function or #+lob) lines can be used to remotely execute code
  blocks...

Because aparently #+call only works on on a line by itself. Check the
following in ob-lob.el:

#+begin_src emacs-lisp
  (defconst org-babel-lob-one-liner-regexp
  (concat
   "^\\([ \t]*\\)#\\+\\(?:"
   (mapconcat #'regexp-quote org-babel-lob-call-aliases "\\|")
   "\\):[ \t]+\\([^\(\)\n]+?\\)\\(\\[\\(.*\\)\\]\\|\\(\\)\\)"
   "\(\\([^\n]*\\)\)\\(\\[.+\\]\\|\\)[ \t]*\\([^\n]*\\)")
  "Regexp to match calls to predefined source block functions.")
#+end_src

This only matches whitespace at the beginning of line followed by
#+call (or lob or function), unlike the embedded calls of the form
src_<language>{body} which can be inlined.

Regards,
.j.
