I used this for a bit, but it 1) needed a hell of a lot of setup and emacs-lisp debugging 2) required me to keep starting a python process to work and 3) kept asking about creating a .ropemacs directory 4) seems way of the top, and slow, and made emacs complain about pymacs stuff all the time.

I switched to Jedi.el now, and removed 150 lines of emacs-lisp code, all I have left in the python section of my dotemacs is:

(setq jedi:setup-keys t
jedi:complete-on-dot t
jedi:key-goto-definition (kbd "M-.") ; who needs TAGS files for python when you have jedi?
jedi:key-goto-definition-pop-marker (kbd "M-,")) ; and M-./, is in my muscle memory now
(eval-after-load "jedi-autoloads" '(add-hook 'python-mode-hook 'jedi:setup))

Sooo much better

Hi I'm new, at all, in emacs and I'm trying to setting up python. I've followed this guide, but it doesn't work for me: it seems that I've got a problem with the .emacs file, in particular whit these parts:
;; Initialize Pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)
;; Initialize Rope
(pymacs-load "ropemacs" "rope-")
(setq ropemacs-enable-autoimport t)

;; Initialize Yasnippet
;Don't map TAB to yasnippet
;In fact, set it to something we'll never use because
;we'll only ever trigger it indirectly.
(setq yas/trigger-key (kbd "C-c <kp-multiply>"))
(yas/initialize)

(yas/load-directory "~/.emacs.d/snippets")

When a restart emacs that's the warning code that I receive:

Warning (initialization): An error occurred while loading `~/.emacs':Symbol's value as variable is void: {rtf1ansiansicpg1252cocoartf1138cocoasubrtf230

Does anybody have an idea on what's the problem?

Hi, I followed this blog and set everything up but the TAB doesn’t work for auto-complete.
I’m using auto-complete.el version 1.0 and every time I tab, it sayslet: Symbol’s function definition is void: yas/snippet-tableAnd i tried ropemacs’s M+/ and it works fine.Any help?

I don't know what kind of incompatibilities are going on in my configuration here, but I (lazily) used your code to install this stuff in my machine, and it ruined the configuration. tab-completion simply stopped working, and there are absolutely no error messages or warnings, anything. Maybe you should take this down... WARNING: DON'T USE THIS CODE, go read up-to-date manuals! If there are any.

Hey, it would be great if you could update it a little... autocomplete 1.3?

Or maybe you will like this new solution.

(defvar is_emacs23 (>= emacs-major-version 23))
(when is_emacs23
(defun python-partial-symbol ()
"Return the partial symbol before point (for completion)."
(let ((end (point))
(start (save-excursion
(and (re-search-backward
(rx (or buffer-start (regexp "[^[:alnum:]._]"))
(group (1+ (regexp "[[:alnum:]._]"))) point)
nil t)
(match-beginning 1)))))
(if start (buffer-substring-no-properties start end))))
)

(defun ac-python-candidates ()
(python-find-imports)
(car (read-from-string
(python-send-receive
(format "emacs.complete(%S,%s)"
(python-partial-symbol)
python-imports)))))

(ac-define-source python
'((candidates . ac-python-candidates)
(prefix . (unless
(save-excursion
(re-search-backward "^import"
(save-excursion
(re-search-backward "^")) t))
(let ((symbol
(python-partial-symbol)
))
(if symbol
(save-excursion (search-backward symbol))))))
(symbol . "py-f")))

(add-hook 'python-mode-hook
'(lambda ()
(setq ac-sources (append '(ac-source-yasnippet ac-source-python) ac-sources))))

Seagle0128 — Sat, 11 Dec 2010 05:31:19 -0000

There is a performance issue about this solution, so have to use:
(ac-ropemacs-initialize)
(add-hook 'python-mode-hook
(lambda ()
(add-to-list 'ac-sources 'ac-source-ropemacs)))

This works well but cannot autocomplete after dot "." immediately.

I fount this article. It works well for me. My configurations instead of ac-ropemacs are below.

(ac-ropemacs-initialize)

(defvar dss-ropemacs-completions-cache nil)
(defun dss/rope-candidates (prefix)
(with-no-warnings
(setq dss-ropemacs-completions-cache
(delete ""
(mapcar
(lambda (completion)
(concat ac-prefix completion))
(ignore-errors
(rope-completions))))))
dss-ropemacs-completions-cache)

(ac-define-source dss-rope
'((candidates . (dss/rope-candidates ac-prefix))
(requires . 0)
(cache . t)
(symbol . "f")))

(ac-define-source dss-rope-dot
'((candidates . (dss/rope-candidates ac-prefix))
(prefix . c-dot)
(requires . 0)
(symbol . "f")))

(add-hook 'python-mode-hook
(lambda ()
(setq ac-sources (append '(ac-source-dss-rope ac-source-dss-rope-dot) ac-sources))))

Hope it also works for you. I am using autocomplete 1.3.1

Hi, thanks for your update. I use the configuration but it doesn't work. The symbol ac-source-rope cannot be found. Could you please look into it? Thanks a lot!

I just set this up with emacs 23 and the new autocomplete version 1.3 (it seems they have upgraded previous versions to 1.x from 0.x as well). It works really well. Here are some slight modifications I made to my .emacs file that allow you to have tab completion with yasnippet on other filetypes as well as python which still has yasnippet and ropemacs enabled.

Modify the last part of the code, delete everything after this line:

(add-hook 'python-mode-hook
(lambda ()

including the "ryan-python-tab" function, and add the following code in its place:

(add-hook 'python-mode-hook
(lambda ()
(auto-complete-mode 1)
(set (make-local-variable 'ac-sources)
(append ac-sources '(ac-source-rope)))
; (append ac-sources '(ac-source-rope) '(ac-source-yasnippet)))
(set (make-local-variable 'ac-find-function) 'ac-python-find)
(set (make-local-variable 'ac-candidate-function) 'ac-python-candidate)
(set (make-local-variable 'ac-auto-start) nil)))

(set (make-local-variable 'ac-sources) (append ac-sources '(ac-source-yasnippet)))
(setq ac-auto-start nil)
(ac-set-trigger-key "TAB")

basically I am setting the global autocomplete trigger key to "TAB" I am still disabling the auto-start feature on autocomplete until you hit the tab key, and I move where you append the yasnippet dictionary to the global part of the .emacs file from the python specific function. It works for me really well so far. Note that this is working with autocomplete 0.3 (or 1.3) downloaded from here:

http://cx4a.org/pub/auto-complete/auto-complete-1.3.tar.bz2

To install this version of autocomplete, decompress the file (there is also a zip version available on that site). Next make a folder in your .emacs.d directory called "auto-complete". Finally in emacs "M-x load-file"
then when it asks you which file to load, navigate to the directory you just decompressed and under the etc/ folder there is an install.el script. Select that script. Emacs will ask you where to install the program. Tell it to install in the ~/.emacs.d/auto-install directory that you just made (really any directory will work though). Finally once it is installed it will give you a few lines to add to the top of your .emacs file. Go ahead and add those lines toward the top of your .emacs file. I don't know if they are all necessary, but I have them there and it works for me.

Hi, I use your configurations. It works well. But emacs uses ropemacs and all completion words are in minibuffer, not popup. Could you give me some suggestion? Well, I use the lastest AC from http://github.com/m2ym/auto.... Thanks in advance!

Re: AutoComplete.el : Python Code Completion in Emacs

Niluge_KiWi — Wed, 12 May 2010 18:00:10 -0000

Ok so with current auto-complete (v1.2), ac-find-function and ac-candidate-function don't exist anymore, the new syntax would be to define a new ac-source, with candidates as ac-python-candidate and prefix as ac-python-find.

I tried, but it seems broken...

I then tried rope: in fact there is already an ac-source for ropemacs in auto-complete 1.2 : ac-source-ropemacs.
The initialization is also managed. I just had to add the followin to my .emacs (it replaces all the elisp code from the article):

(ac-ropemacs-initialize)
(add-hook 'python-mode-hook
(lambda ()
(add-to-list 'ac-sources 'ac-source-ropemacs)))

I don't know what was the goal of ac-python-candidate and ac-python-find, but I don't use them and it works well.

I know that it's dead, but it's worth a try :)
I used the init-python.el from github and I still cannot get the tab to work, it just calls rope and yasnippet but I cannot do an indent tab anymore
no explicit errors
any suggestion?

Hey dude.

I just came here looking for python auto completion in emacs. Haven't tried it out yet (I'm on a deadline, so I'll check it out when I have the time & energy). But I did take a moment to click on your facebook picture, and read the sign in the background. As a fellow anti-prohibition, emacs and python user, I thought I would just say hi. so hi!

Ryan,

have you also set up a python debugger in emacs (similarly to how John has set it up in vim)?

Chris R — Sun, 14 Feb 2010 17:41:40 -0000

This whole thing is pretty damned cool, but I've got a problem that crops up all the time where ropemacs stops returning candidates for reasons unknown. Do you happen to have a post waiting in the wings on how to troubleshoot ropemacs issues? That'd be REALLY useful.

prasant — Sun, 13 Dec 2009 08:07:12 -0000

In Windows 7 i get yasnippet completion but not python code completion. I probably have some configurations elsewhere that interferes with your instructions.

But your emacs configuration on github works fine; after adding a few missing files and renaming some directories. Thanks very much.

Hi! So what about auto-complete 0.2 ? Could you please look at that? Thank you very much for all this! Your article is magic :-)

rileyrgdev — Thu, 22 Oct 2009 13:47:12 -0000

The other option is to use company-mode which has built in rope completion for python files. My own setup which includes flymake to provide a live "pylint" presence in a python buffer is here:

Oh, When will you update this great post to support autocomplete version 0.20 or 0.30? I am eager to know that. I will appreciate it :)

This is a wonderful post! Thank you so much!!

Any update on the updated version with auto-complete 0.2.0 ?

Thanks again.
