auto-complete mode with org-mode

auto-complete mode with org-mode

[phaebz]

I am using org-mode v. 7.3 and auto-complete v. 1.2

I added org-mode to "ac-modes" as described in the documentation. When typing in an org-mode buffer, I correctly get the popup-menu from auto-complete mode. If I then press TAB to complete the word, nothing happens - since TAB is bound to org-cycle.

I am not really familliar with ac-mode, but I guess it could be using a hook when populating the popup menu, so that I could bind the tab key in this hook ac-specific and bind it then again to org-cycle when after-completion-hook is run, in case there is one... I just wanted to ask here if others have a similar setup/issue and how it is solved elegantly, i.e. in org-mode style.

Thank you

Michael Bach

org mode somehow (I have no idea how or why) manages to distinguish
between TAB and C-i and this distinction is inherited by minor modes
operating within an org mode buffer.  For auto-complete, the fix is
easy:

#+begin_src emacs-lisp
(require 'auto-complete)
(require 'auto-complete-config)
(ac-config-default)
;; (define-key ac-complete-mode-map "\t" 'ac-expand)
(define-key ac-complete-mode-map [tab] 'ac-expand)     ; <<--- add this line
;; (define-key ac-complete-mode-map "\r" 'ac-complete)
#+end_src

I've included two commented out lines: they are the defaults set by
auto-complete.  I found, before adding the annotated line, that C-i
worked as expected within an auto-complete pop-up but the tab key
didn't.  With this key binding, it does.

I do find, however, that although the \r (return key) works (accepts the
completion proposed by auto-complete), *sometimes* org-mode also
interprets it so that two things happen when I hit the key.  I've not
yet figured out when it does this in any reproducible manner
unfortunately.

Thank you for the information!

remapped the ac-expand now. There is just one more annoyance: When the completions popup-menu gets displayed, for every line that has an org-style *heading, the completions line drawn over it starts just with the first letter and then an ellipsis "..."

I try to present an org snippet for an example:

#+BEGIN_org-sample
* first heading
--- popup-menu starts here ---
cobra
c...
c...
c...
c...
computer
connection
--- popup menu ends here ---
co<point>

some more text
#+END_org-sample

All lines in the popup menu that start with c..., would be real completion candidates, which get folded away because of underlying folded org-headings.

Any ideas on this?

I have the same problem.  I am not sure how the ellipsis are "drawn" in
the buffer but maybe the issue has to do with overlays?  grasping at
straws here... maybe somebody else can help.  it is a slight annoyance
and only happens in org buffers, and only when there are collapsed
headings in the vicinity of where you are typing.

Hm. Well thanks for thinking about it anyway. It is really just a slight annoyance, but as the number of org-buffers increases - they seem to fit more and more purposes the more I use org, esp. for quick write-ups where this issue annoys me the most - this annoyance increases also ;)

But then it is just so nice to use org anyways, I gladly accept this sort of behaviour.
