Emacs + Rope + Python produces lisp error

Question

I'm trying to use Ropemacs with AutoComplete in Emacs but I keep getting a Debugger error:

Debugger entered--Lisp error: (void-function rope-completions)
  (rope-completions)
  eval((rope-completions))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)

The symbol rope-completions has no documentation from C-h S. It only appears once, in the auto-complete-config. I've downloaded the latest ropemacs, ropemode, pymacs, python-rope and probably borked any apt system consistency I had.

When I remove this function from the config files auto-complete turns the cursor red when it tries to complete. I can't find reference to this function anywhere on my system.

Auto-complete is working perfectly for me in Lisp. How can I get auto-complete and Rope to work together to give me auto-completion for Python in Emacs?

EDIT: I cannot see the definition of rope-completions through C-h f. Here is the output of my Pymacs buffer:

<23 (version "0.24-beta2")
>45 eval pymacs_load_helper("ropemacs", "rope-")

Do you have something like this in your emacs setting? (see also: agr / ropemacs / overview — Bitbucket )

(require 'pymacs)
(pymacs-load "ropemacs" "rope-")

If you have it, check that you have ropemacs command such as rope-open-project (C-x p o).

Note that rope-completions is defined as python function so you won't see its definition in elisp source.

You will see this when you hit C-h f rope-completions RET (not C-h S), if you load ropemacs properly.

rope-completions is an interactive Lisp function.

(rope-completions &rest ARGUMENTS)

It interfaces to a Python function.

Thanks for your reply! I have copied enigmacurry.com/2009/01/21/… almost directly into my .emacs file. It still doesn't work :(

Can you check if you load ropemacs properly, like I described above? BTW, if you don't care about ropemacs and just want completion, maybe you should try chrispoole.com/project/ac-python.

C-x p o is bound to the command icicle-bookmark-other-window (even in a Python buffer) and the command rope-open-project doesn't exist. I'll try out the link you pointed out today.

Then the problem is ropemacs (or pymacs), not auto-complete. First, check pymacs is loaded correctly. Remove all (autoload 'pymacs-...) lines and put (require 'pymacs). If you have error when you start emacs, you don't have pymacs.el in load-path. If can see documentation when you type <f1> f pymacs-apply RET, pymacs setting is OK. Then check that you can import rope in Emacs. Start python shell and check if import rope, import ropemacs or import ropemode fails. I guess at least one of them fails. If so, put these modules in your PYTHONPATH.

You say you copied "almost directly", but you never mention what version of ropemode/ropemacs you have. I had to install from hg at least to get completions (it's defined in ropemode/interface.py as def completions, the prefix "rope-" is added by pymacs)

The only way I was able to do it in the end was to ignore all other tutorials and just use the Emacs For Python Github. It works really well, combines a lot of packages that I was looking to use anyway and is easy enough to configure so that it doesn't mess up my existing bindings and settings.
