On Emacs 24.3.50.1 I have auto-complete mode up and running (by using source code and following their setup, plus other's added suggestions). Then I installed ac-slime from ELPA-land (Version: 20131005.1126), which puts it in ~/.emacs.d/elpa/ac-slime-20131005.1126. However, the .emacs usage code doesn't seem to make any specific note of where this directory is. I suspect I don't really have ac-slime working properly as I can't choose from pop-up suggestion list with return key. Any ideas how to get it working?

I'm trying to setup and android development on my mac using Emacs and CEDET (I hate Eclipse, and I want to keep using emacs, but I want the auto-completion, so this setup seemed perfect).
However, I want to use emacs in the terminal. I have a problem with the auto-completion. CEDET is trying to use the graphical menu "popup-menu" and I got an error in CLI mode: "Symbol's function definition is void: popup-menu", which makes perfect sense.
My question is, is there any way to use Emacs' termcap menu for CEDET auto-completion?
Thanks!
Thibault.
Edit: you can find my emacs configuration there: https://github.com/tbronchain/emacs
Edit2: here are some screenshots showing 1- What is the CEDET auto-completion in GUI mode 2- the menu I would like to use for CEDET in CLI mode
CEDET = http://bit.ly/1iptfq3
auto-complete = http://bit.ly/1kZVDz9
I got my answer!
I didn't succeed to replace the menu by auto-complete, however, it works perfectly with company! It is a little bit more messy than the GUI menu, but it's still awesome!
Thanks to #Stefan for helping with this!
I will post my full configuration on github when I'll be done with this configuration (I'm trying to optimise the keyboard shortcuts a bit).
Cheers,
I recently upgraded to emacs 24.3.1 in order to use a new mode for programming in D. I seem to have introduced some problem with my other modes now (Java, C++ C I'm just using whatever comes with emacs). When I scroll up/down in a buffer, the text displayed is totally messed up. As in lines mixed together, indentation screwy, cursor not modifying where it looks like it is. If I hit ctrl-l the screen refreshes and all is good. I noticed this problem every once in a while with my previous version when editing C .h files. But now it's happening on every single buffer. I can't work with it. Every time I move up/down I have to refresh the screen. I can't find anything similar to my problem with a google search. Might end up being an issue with some incompatible version of a dependency. Here's my system stats.
CentOS release 5.4 (Final)
linux 2.6.18-164.el5
emacs 24.3.1
I don't even know what other libs emacs might depend on. I'll be happy to post versions of anything that might be relevant.
Thanks
Since you say that this happens also with emacs -Q, i.e., without your init file, consider filing a bug report: M-x report-emacs-bug. For that, try to give a short, reprocible recipe, starting with emacs -Q. Emacs Dev will take a look and let you know whether they think there is a bug.
Using report-emacs-bug also automatically gathers info about your Emacs version etc., and includes it with your bug description.
I installed emacs prelude in cygwin via the simple curl installation. I open a test.js file and try typing "document." to see autocomplete but nothing pops up. Admittedly I'm totally an emacs/prelude newbie, is there something else I should be doing to get it to autocomplete?
Does your Prelude installation include library Autocomplete? And is that what you mean by "autocomplete"?
Give a recipe showing what keys you hit and what you expected to happen vs what actually happened.
Consult the Prelude manual.
Ask the preluddites themselves (sorry; couldn't resist): emacs-prelude#googlegroups.com.
I see only a few Google hits in English for all three keywords: "emacs prelude autocomplete", and none of them mention using Prelude and Autocomplete together.
Your question is too general, I am assuming by auto-completion you mean
A popup that displays the possible completions for currently typed
word and allows you select one of the candidates
Something like this
Last time I checked prelude did not come with such autocomplete but you can configure emacs to have this kind of completions. You will have to install a library that provides the completion UI, I know of three libraries that do this in emacs (ordered according to my familiarity with them)
1) auto-complete
2) company
3) completion-ui
You can install any one of these (auto-complete and company have a good a number of backends, I do not know much about completion-ui). If you are using emacs 24 this will be as simple as M-xlist-packagesRET, marking the package to be installed with I and then typing X (for auto-complete you will need to add melpa to your package archive, refer to the websites above for more on installation)
These will provide a basic completion interface. auto-complete by default offers words in current buffer for auto-completion. However for 'intelligent' auto-completion you will need to configure these to use a completion backend. This will vary according to the individual language you want completion (eg. jedi for python, tern for javascript, eclim for java etc), as such you will need to ask specific questions to get helpful answers.
According to this answer, Emacs + Slime already has much advanced functionality. So how can I get syntax coloring, auto-completion, and perhaps even version control management, set up and running in my copy of Lispbox?
If it's of any help, I have installed Lispbox on Mac OS Lion.
Syntax highlighting should already be working as soon as you load a lisp file in Emacs, regardless of whether you've got SLIME installed or not. If it's not, try doing M-x font-lock-mode and see if that turns it on.
Version control isn't provided by Emacs or SLIME, but Emacs can integrate with pretty much any version control system you care to use. I recommend Mercurial or Git. Emacs should start vc-mode automatically when you open a file that is in one of the supported version control systems. The manual includes extensive documentation, do M-: (info "(emacs)Version Control") to jump right to it.
Auto-completion is more complicated. There is more than one way to skin this cat, but for Lisp SLIME's default method should be good enough. Use M-TAB to complete the symbol at point.
I have been a programmer for a decade now, but I believe this is the first time I've ever asked a question on a forum. I just can't figure this out and can't find the answer already online.
I am trying to turn on CUA mode so that emacs is more bearable for a windows user (normal copy paste functions). I am running Windows 7 and installed emacs through the Lisp In A Box package. I understand that I need to add a line to my .emacs file or init.el file. I'm not sure which, but I can't find either in my Lip In A Box install directory. The emacs package install also did not come with any tutorials or help files, so its really hard to pick this up.
I am stuck, any help is greatly appreciated!
The .emacs can be found by looking at the answers to this similar question.
Regarding documentation and tutorials, it looks like the link you provided for "Lisp in a Box" says:
If you are new to Emacs, it is
recommended that you read the Emacs
Tutorial which you can access from
with Emacs by going to the Help menu,
or by typing Control-h, letting go,
and hitting t. A more extensive manual
is also available from the Help menu,
or on the web at
http://www.gnu.org/software/emacs/manual/.
Which makes it sound like the manual is there, and certainly the tutorial (I made bold the directions to get to the tutorial).
As far as other places to get information, there is a collection of screencasts on the wiki.
Your question doesn't specify whether or not you what to add to your .emacs to activate CUA mode. You can check out the CUA mode documentation on the wiki (which has links to the manual). The minimal installation is just adding this to your .emacs: (cua-mode t).
For GNU/Emacs, you can choose to use any one of the following three file names as the start-up configuration file:
${HOME}/.emacs
${HOME}/.emacs.el
${HOME}/.emacs.d/init.el
It would probably be a good idea to decide on one of the three options and then stick to it - the first one seems to be the most widely used one. In any case, ${HOME} stands for your home directory -- which is likely to be different from the Lisp In A Box install directory!
Coming from a Unix tradition, Emacs understands ~ (tilde) as an abbreviation for your home directory, so you can visit the .emacs file by typing:
C-x C-f ~/.emacs [ENTER]
(Note that the capital C is Emacs standard notation for a combination of the CTRL key and a second key, i.e. here you press CTRL-x CTRL-f which stands for "find-file" and will then ask you for a file name in the bottom part of the Frame (aka mini-buffer).)
If these are your first customizations, you will just see an empty buffer. Enter
;; start CUA mode every time Emacs starts
(cua-mode t)
and save the buffer with C-x C-s.
Next time you start Emacs, CUA mode should be turned on automatically.
What the others have told you is true: Simply adding (cua-mode t) to your dotfile would be sufficient. HOWEVER: Lisp in a box' Emacs doesn't load this file by default.
Therefore, be sure to edit the shortcut so that it does load the dotfile. This is important, because otherwise you would get weird behavior, where you would add the correct line to the dotfile, start emacs, and then not get cua mode. That would suck.
The reason it does this is to ensure that it starts a vanilla emacs everytime, instead of finding, say C:/_emacs and loading that instead, giving you another user's customizations and confusing you.
The flag for not loading an init file is -q or --no-init-file. Also make sure that --no-site-file is not there.
(I realize that this is an old post, but I found this while looking for something related, and I don't want people walking away frustrated over something that doesn't work.)
