Perfect python environment
jakob fischer
I am running Ubuntu 9.4. Since three days I am trying to install The
perfect python environment on emacs according to the howtos
http://www.enigmacurry.com/2009/01/19/my-emacs-config-on-github/ and
http://hide1713.wordpress.com/2009/01/30/setup-perfect-python-environment-in-emacs/
I allways get a void on functions in rope, even if I follow the hotow
step by step or just clone the github stuff from enigma curry. I
istalled the suggested versions of the libs and so on.
Does anybody have some knowledge about this perfect python environment
for emacs? And how can i get emacs to give me some decent debub info.
Note: I am pretty much an emacs newbie and do not understand lisp code.
Thank you, jakob

even when installed, i found severe bugs that crash emacs (don't
remember what it was).
If you just want completion in python, consider using ipython as
python-shell in emacs and use anything-python for completion.

It seem your configuration of anything-ipython is wrong, be sure to read
carefully the instructions in anything-ipython.el.
I can't reproduce your error.
Here is my config:
,----[ Config thierry anything-ipython ]
| (require 'anything-ipython)
| (add-hook 'python-mode-hook #'(lambda ()
| (define-key py-mode-map (kbd "M-<tab>") 'anything-ipython-complete)))
| (add-hook 'ipython-mode-hook #'(lambda ()
| (define-key py-mode-map (kbd "M-<tab>") 'anything-ipython-complete)))
|
| (add-hook 'ipython-shell-hook #'(lambda ()
| (define-key py-mode-map (kbd "M-<tab>") 'anything-ipython-complete)))
| (when (require 'anything-show-completion nil t)
| (use-anything-show-completion 'anything-ipython-complete
| '(length initial-pattern)))
| (define-key py-mode-map (kbd "C-c M") 'anything-ipython-import-modules-from-buffer)
`----
To have completion in python buffer (i.e in your python file, not the
shell) you have to start first the ipython interpreter, and then load
all the modules you have in your python file.
Load modules one by one in ipython interpreter or use from your file
C-c M (see above).
Be sure also to setup python-mode (PYTHON-MODE, not the bad one that
come with emacs) correctly.
Let me know if you have more problems.

I can't reproduce, all work fine here.
That error come from anything.el itself (in `anything-get-current-source').
It is not related with anything-python.el specialy.
I suspect you will have the same error with others anything modules
also.
You have to make anything working.
Can you describe how did you install anything, what anything files you
load etc...
Be sure also to use anything-config.el.(it will require anything)
Also, don't add anything-python source to anything-sources, use it only
with function `anything-ipython-complete.'

BTW what is os.fcn? i have no completion on that, but yes on os.fc
Anyway if you forget to launch ipython or to load modules,
anything-ipython complete nothing, do nothing,
it don't crash if you forget that, it just wait.

So good you have python-mode.el.
