auto-complete shows ugly when the lines have 'tab's.
Below is an example (table size is set to 8)

;;;;;;;;;;;

1.   (def
   

2.'tab'
;;;;;;;;;

in line 1, there are 7 'space' before '(def'
in line 2, there only 1 'tab' with table size set to 8,
and then we run 'ac-start' after '(def' in line 1
After completion, in line 2, the popup is break into to parts, just as
following:

x xxxxxxxxxxx

x is stand for character with grey background.

Hi there, and thanks for ac! Having some problems running with foomatic (need by cups/hplip to print) is on a machine:

Can't type '/' slash, otherwise freezes:

Tramp: Opening connection for foomatic-db-1 using scpc...
Tramp: Sending command `exec ssh   -o ControlPath=/tmp/tramp.26554bV1.%r@%h:%p -o ControlMaster=yes -e none foomatic-db-1'

It hangs for > minute, really boring as slashes are pretty common in line beginnings...

A calltip that shows the documentation (maybe starting with a condensed summary?) and the parameters, maybe with the current one in bold would be nice.

Most of the time you don't want auto-complete to pop up when you are editing a string or a comment. It would be nice if there's an option so I that I can disable this behavior.

I use auto-complete and cygwin-mount in js2-mode. Then when I input "//" in a .js file as the single-line comment. Auto-complete search the shell commands by "//". That always lasts for a long time. Meanwhile the emacs war blocked. Although "//bin", "//cygwin" and others may be prompted finally.

Moving from version v1.0 to v1.2 of auto-complete I found an incompatibility with FlySpell. Auto-complete menu and completion are very slow to appear (much slower that the time set in the timers, something like a couple of seconds, or more)

Playing with 'git bisect' I found that the commit where the problem appeared is the one obtainable with the command

git checkout ef46dc4cdccdfb4a5bc5675893300fc9ddf11a07

in particular this is the commit that introduces the timers instead of post-command-hook.

For my tests I used the following dotemacs as initfile. When I disable flyspell-mode the auto-complete works fine and fast.

I lauched the tests with the following command line:

emacs -Q -l dotemacs file.txt

where I tried both emacs versions 22.2.1 and 23.1.50.1.

Here it is the dotemacs

;;; Simple .emacs for testing the functioning of
;;; auto-complete and fly-spell mode.
(setq load-path (cons "./auto-complete/" load-path))

Bye,

It's really annoying.

I'm editing a css file with custom properties

@page {
margin: 27mm 16mm 27mm 16mm;
size: 7in 9.25in landscape;
}

http://www.princexml.com/doc/7.0/

They are from Prince.

When I try to add another field, autocomplete would freeze emacs. I know they are not valid CSS. Can it not freeze emacs when there're errors?

emacs 23.1.1

auto-complete renders incorrectly. Screenshot here:

It may look like newlines are never getting inserted, but sometimes it inserts newlines on some, and omits them on others.

Kept getting error about void function ac-gtags-candidate. Found the problem:

Hi again,

I have

Any ideas?

Thanks.

Here is a patch that adds the option of automatically expanding the completion when there is only a single candidate. This is particularly nice of ac-auto-start is nil and completion is started from a key binding.

There is a new defun: ac-start-and-expand-single. It functions exactly like ac-start, but if the initial completion list contains only a single candidate, it is automatically expanded and completion ends.

There is also a var: ac-always-expand-single-p. If non-nil, a candidate is automatically selected whenever the candidate list is reduced down to a single item.

Hi Tomohiro,

Thanks for the great package.

One issue with the latest git head.

I have

(ac-set-trigger-key "TAB")

and this assignes 'ac-trigger-key-command to TAB but it doesn't trigger the completion.

I also have ac-auto-start 2.

From the source I see

(defun ac-trigger-key-command (&optional force)
  (interactive "P")
  (message "%s" last-command) ;; <- my addition
  (if (or force (ac-trigger-command-p last-command))
      (auto-complete)
    (ac-fallback-command 'ac-trigger-key-command)))

last-command here is the one previous to ac-trigger-key-command and I am always
getting into ac-fallback-command no matter what; ac-trigger-commands is '(self-insert-command).

This version works ok:

(defun ac-trigger-key-command (&optional force)
  (interactive "P")
  (if (or force
      (eq this-command 'ac-trigger-key-command)
      (ac-trigger-command-p last-command))
      (auto-complete)
    (ac-fallback-command 'ac-trigger-key-command)))

Thanks,
Vitalie.

1. Open emacs -Q (GNU Emacs 23.1) and auto-complete to load-path.
2. M-x auto-complete-mode
3. Customize to turn of ac auto start
4. Add "defun123" and "defun456" strings to scratch buffer
5. Type "def" and M-x auto-complete
6. No pulldown appears unless you type or delete another character. After that pulldown menu works correctly (i.e. updates corresponding to what you type).

Some people still use XEmacs. So auto-complete should support XEmacs.
However, I'm not sure that we have to support XEmacs.
Anyway, I'll spend little time to look into XEmacs and such supports.

Helllo!

I've got a strange issue with autopairs and auto-complete, similar to this: http://code.google.com/p/autopair/issues/detail?id=8
I use emacs 23.2 from debian squeeze repo, autopairs from svn, auto-complete from github (with el-get).
The RET key does not complete the candidate what is choose from the list. If i deactivate autopairs it works as expected.

Strange issues: if i start a tty emacs, it works, with an X emacs it does not work. After reading the manual, i tried C-m and it works both tty and X! I use Hungarian keyboard layout.
Relevant config pieces:

autopairs:
(autopair-global-mode 1)

auto-complete:
(require 'auto-complete-config)
(ac-config-default)
(setq ac-comphist-file "~/.emacs.d/cache/ac.cache"
ac-dwim t)
(setq-default ac-sources '(ac-source-words-in-same-mode-buffers ac-source-words-in-buffer ac-source-yasnippet))
(ac-linum-workaround)

For example, if I enable flymake for ruby-buffers, auto-complete stops working (trigger key does nothing). I'm using the latest version as of May 18th 2010.

this is low priority.
but since linum is quite a nice feature, it would be great if autocomplete would work with this.

When you trigger a complete overlay menu, the text on the right edge of the menu is shifted to the right a bit. When the menu is gone, the text is back to the original location creating a jumpy effect. This shouldn't happen.

My custom face use italics for comments, and when auto-complete's popup is over those comment lines, some candidates are shown with italics - which is undesirable since those candidates stands out for nothing...

So I have to change the following few lines

(defface ac-candidate-face
  '((t (:background "lightgray" :foreground "black" :slant normal :weight normal)))
  "Face for candidate."
  :group 'auto-complete)

(defface ac-selection-face
  '((t (:background "steelblue" :foreground "white" :slant normal :weight normal)))
  "Face for selected candidate."
  :group 'auto-complete)

body {
    background-color: white;
}

Putting your cursor over the ; and hitting the ac-expand key, it tries to complete for colors. This is quite annoying.

Using the latest version from git after a . or a -> in c/c++ mode it's needed at least another char to show the completion menu.

Using version 1.3.1 everything is working fine.

When at the end of the line, and at the end of a "completion" (as in, no characters left in a completion), a newline shouldn't require two "Enter" keypresses.

I found the popup menu of auto-complete can appear in a table created by 'table-insert' and it corrupts the table, so I wrote a patch which adds a new option 'ac-non-trigger-commands' to avoid the problem.

http://github.com/iRi-E/auto-complete/commit/7b26d287551441cdb9899db7bce3b477bb81fc50

Please check it.

Copied from http://code.google.com/p/auto-complete/issues/detail?id=5.

This is enhancement targeted for SVN HEAD.

As it stands now auto-completes shows a candidate menu after either a key combo is triggered
or after ac-auto-start. This creates a couple of problems:

1. For large documents, it can be very slow because after every ac-auto-start characters, which
   is often short, auto-complete will try to pull candidates from all the sources for every character
   entered, which results in very visible lagging. On my machine, for a python file with words-in-
   buffer and ropemacs as sources, after typing a series of characters quickly, displaying the
   candidate menu can take about 5 secs.
2. For small documents, having the candidate menu pop out for every key entered is also very
   annoying.

I think 1) is caused by auto-complete tries to pull candidates for every keystroke immediately, so
it gets slower and slower as the buffer grow and more characters are typed in.

I think the best solution is to mirror what Eclipse and other IDEs do, which is simply have the
menu display immediate after certain special keys like . and ->, which is the current behavior. In
addition, for every self-insert-command after ac-auto-start, auto-complete should instead
reset a menu display timer, which should set to 200ms by default. When the time is up, the
menu is displayed. This should speed up auto-complete considerably.

I just used the newest version of install.el, and it specificed to add (ac-config-default) to my .emacs file. However, "M-X-ac-config-default" doesn't work - is this an installiation error, or does it no longer exist?

2010-09-17

just installed autocomplet. Very nice.

here's a case that freeze my emacs, had to force restart emacs. Happened twice consecutively, so probably reproducable.

in a css file, with this line:

blockquote{border-left:solid black;padding-left:1ex;color:#1f3f2f}

move your cursor after the #. Do a subword-kill, then undo, to grab it.
Then, move cursor to the b in “black”. Type a “#”, then do a yank.

After typing the “#”, my emacs freezes.
This happened to me twice.

Hey there,

Could you please make auto-complete available on marmalade-repo.org?
It makes installing and using packages a whole lot easier for users.
I'd be grateful to be able to have auto-complete installed consistently
without human intervention across all my machines.

Thank you. =)

Cheers.

I would like a custom option that places me immediately into isearch-mode without having to type \C-s.

2. Open hoge.el

3. Type "set"

In Emacs 24, completion works but quick help is not shown. Furthermore, pressing F1 (or C-?) does not show popup help. Note that normal help (e.g., F1 f setq RET) works.

EDIT: I noticed that quick help and popup help for nil work.

requiring auto-complete on emacs 22 automatically starts the auto complete mode for some reason, and setting (global-auto-complete-mode t) gives an error:

Wrong number of arguments: called-interactively-p, 1

I use these configurations for python-mode:
(ac-ropemacs-initialize)
(add-hook 'python-mode-hook
(lambda ()
(add-to-list 'ac-sources 'ac-source-ropemacs)))
It works well. But emacs uses ropemacs and all completion words are in minibuffer, not popup. I use the lastest AC from http://github.com/m2ym/auto-complete.
No this issue in other modes, including c++-mode, java-mode.

popup.el contains unintentional NULL char. Could you remove it?

(setq menu (popup-create point width height
:around around
:face 'popup-menu-face
:selection-face 'popup-menu-selection-face
:margin-left margin-left
:margin-right margin-right <----- Here. There is a NULL char at the end of this line.

Looks like describe-function-1 now raises an error if current-buffer is not in help-mode, so ac-symbol-documentation fails to gather the info needed for the help popup.

I've looked at the help.el and help-mode.el code, but haven't figured out how to work around this problem.

Hi Tomohiro, sorry but is there any way to add lua support for autocomplete...I was reading the manual and no found how do it...is it simple or a bit complicate?...are there resources where I can found a explanation...many thanks, congratulation for your amazing mode and good luck
