Using CEDET, everytime it autocompletes after a member selection "." or ">", another buffer overrides the current one. I find it really annoying.
Also, how can I use page up/page down with the small buffer of auto-complete mode?
For your #1, consider filing an Emacs bug report (CEDET is now part of vanilla Emacs), using M-x report-emacs-bug. The Emacs developers will determine whether the behavior really represents a bug (or an enhancement request).

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.
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.
Emacs is my editor of choice, and I use the cscope intergration xcscope.el provides. Recently I had a flirt with Vim. I decided to stay with Emacs, but one of the things I really liked in Vim was how I could control where my cscope windows should appear. Using cscope_maps.vim (http://cscope.sourceforge.net/cscope_maps.vim) I get shortcuts that let Vim open search results in the same buffer, a new horizontal or a new vertical split.
In Emacs a the cscope buffer just pops up in a window somewhere, according to some rules I don't know. My guess: A new window is opened if I have only one. If I have more, the one I've been away from for the longest time is used.
Pin Emacs buffers to windows (for cscope) is the only related topic I've found that helps a bit, but that doesn't make it near as flexible as the key bindings in Vim.
Anyone got a better cscope setup in Emacs than what xcscope.el provides? I don't know lisp, so I have no idea how hard it would be to make this work the way it does in Vim.
Emacs 24 (not yet released) changes radically how it is decided which buffers are displayed in which windows. In principle it should give you more fine-grained control. In any case, how you solve the problem for Emacs 24 will be different from how you solve it for older versions.
Consider filing an Emacs enhancement request to specifically get behavior more like what you had with Vim. To do that, use M-x report-emacs-bug.
I am very familiar with emacs--and I realize that there is nothing that it cannot do--but there are some things that it does not do well or efficiently. So, being between projects I am open to the idea of switching to a full-featured IDE such as Eclipse.
With muscle-memory being what it is, I would like to make Eclipse as emacs-like as possible. I have already discovered the excellent Emacs+ plugin which gets me about halfway there. However, I am still missing the following features of emacs which I routinely rely upon:
shell: It's not just a shell, it's also a buffer.
occur: Search->File... is close to what I want, but I just want it to search the current file--which might be a text file, a logfile, or a shell buffer, or whatever.
align-regexp: This awesome little command in emacs helps me make files more readable, and alignment helps with keyboard macros.
What plugins would you recommend to solve these issues? Are there any other emacs features you miss in Eclipse or plugins you would recommend?
Please, no emacs/vi zealots asking why on Earth I would do such a thing.
For the shell you have WickedShell
Ctrl+F is enough to trigger a Search within the current file. (does not create a new buffer with matched lines)
Only Mark Occurrences is about highlighting occurrences, but that is not as advanced as the Emacs function.
Formatter options can emulate "align-regex" function, as described here.
Preferences -> Java -> Code Style -> Formatter.
Click 'Edit' on the profile (you may need to make a new one since you can't edit the default).
In the indentation section select 'Align fields with columns'.
Then, in your code Ctrl+Shift+F will run that formatter.
I can confirm Brian's suggestion (Emacs key-bindings). What I do to resolve this dilemma is to use both Emacs and Eclipse simultaneously. They are both very good at reporting external changes to files so there is minimal chance of tromping on edits (but it can happen). More to the point, you can leverage the strengths of both tools without having to give up either one. The combination of using both tools and Eclipse having Emacs key-bindings makes this quite satisfactory for me.
IIRC (It's been a while since I've used eclipse) eclipse has a "use Emacs key-bindings" mode. I believe that there's also the option to tell eclipse to use emacs as its own editor...
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.)
