With emacs24 I'm using org-mode 8.2.8 installed from the tar.gz file available on orgmode.org.
I'm trying to get the infopath loaded so that C-h i m Org Mode RET will give me the org manual.
The org faq mentions two methods - both of which make reference to /path/to/org-mode/info but there isn't any info directory in the 8.2.8 org-mode root directory, only a doc directory.
Compiling org-mode 8.2.8 with the make command from the org-mode 8.2.8 root directory builds the file /usr/share/org which seemingly contains the manual for org 8.2.8 but I'm not able to load that with neither methods mentioned in the FAQ.
Note: I've previously asked this question. In that case I was using the version of org-mode that shipped with emacs24 and apt-get install emacs24-common-non-dfsg got me the man pages. This is a different case in which I'm using another version of org-mode than the default.
The doc directory contains org.texi. Add that to Info-directory-list.
(add-to-list 'Info-directory-list "/path/to/org-mode/doc")
If info hasn't been loaded yet, use
(eval-after-load "info"
'(progn
(info-initialize)
(add-to-list 'Info-directory-list "/path/to/org-mode/doc")))
or
(add-to-list
'Info-default-directory-list "/path/to/org-mode/doc")
I'm using the following "generic" solution to add a couple of Info paths:
(with-eval-after-load "info"
(setq Info-directory-list
`(,(expand-file-name
(concat (file-name-directory (locate-library "org")) "../doc/"))
"c:/cygwin/usr/share/info/"
,#Info-directory-list)))
(For Emacs 24.4, because of the with-eval-after-load)

I used to have the following line in auto-complete:
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/auto-complete/dict")
(ac-config-default)
but now that I installed auto-complete as an Emacs package, I don't have an auto-complete folder in my .emacs.d directory anymore, so the second line above does not work.
This leads me to two questions:
More generally, where are packages installed?
How should I adapt my add-to-list line now that I have auto-complete installed as a package?
By default (in newer versions of auto-complete) the directory used will the the one in the site-lisp folder where emacs installed the package so that line is not required. Simply placing
(setq-default ac-sources
'(ac-source-abbrev ac-source-dictionary
ac-source-words-in-same-mode-buffers))
In your .emacs will let auto-complete know the sources you want for completion and the dictionary file will be placed appropriately.
If you want a custom dictionary (at least what I did) was
(add-to-list 'ac-dictionary-directiories "~/.dict")
Just make sure the directory you put exists.
EDIT: Forgot to mention that this is only if you want to add custom dictionaries to auto-complete (Java object higlighting or custom keywords, etc...). The language ones are enabled by default.

Emacs 24 Package System Initialization Problems
I am using Emacs 24. I have the ELPA and Marmalade repos added. Using 'package' I installed 'auto-complete'. I have the following lines added to my init.el:
(require 'auto-complete-config)
(ac-config-default)
When I start Emacs, I get the error
File error: Cannot open load file, auto-complete-config
But then I use
M-x load-file
and load the same ~/.emacs.d/init.el file, it then works fine with the prompt saying
Loading /home/user/.emacs.d/init.el (source)...done
How is the usual loading different from the 'M-x load-file' command? In the start of the init.el file I do the following, is this somehow effecting the package from loading.
(add-to-list 'load-path "~/.emacs.d")
(load "custom_code")
As mentioned in the comment below: The answer by phils to the duplicate question is probably more helpful than this one
This almost certainly means that your init.el file is getting run before the code that sorts out the packages for package.el. The latter code adds the directory with the auto-complete library to your load path.
I'm still using ELPA, rather than package.el. With elpa, there's a snippet that looks like this that gets installed at the bottom of your .emacs.
;;; This was installed by package-install.el.
;;; This provides support for the package system and
;;; interfacing with ELPA, the package archive.
;;; Move this code earlier if you want to reference
;;; packages in your .emacs.
(when
(load
(expand-file-name "~/.emacs.d/elpa/package.el"))
(package-initialize))
As the comment suggests, you probably want to put your equivalent package.el initialization code before the stuff that loads init.el.
Finally: I notice you mention adding .emacs.d to your load-path. The Emacs load path is not recursive, so that probably won't do what you need (assuming that your libraries live in subdirectories). Years ago, I wrote this snippet to load up various libraries of elisp code that I'd written. You might find it useful. (Obviously, it'll only work on unixy systems with a shell and a find command. It's reasonably slow, but this seems to be shell-command-to-string, which takes several milliseconds even running "echo hello" or the like)
(defun find-elisp-dirs (dir)
"Find all directories below DIR containing elisp sources, ignoring those"
(split-string
(shell-command-to-string
(format "find %s -iname '*.el' -printf '%%h\\n' | sort -u"
(expand-file-name dir t)))))
I see at this link how emacs prelude ensures that a set of packages is installed when emacs starts. I was wondering if I could somehow extend the variable prelude-packages to add some other packages, without changing the prelude-packages.el file?
Barring that I was wondering how I could define a list of packages that are installed at start-up if they aren't currently installed.
You can place a .el file in personal/ directory in Prelude. Prelude loads any .el file it finds there in an alphabetical order. Below is the content of my personal/00-packages.el file.:
(require 'package)
(add-to-list 'package-archives
'("marmalade" .
"http://marmalade-repo.org/packages/"))
(package-initialize)
;; My packages
(setq prelude-packages (append '(
drupal-mode
nginx-mode
) prelude-packages))
;; Install my packages
(prelude-install-packages)
"00" is added to the file name to ensure that the file is loaded before all personal customizations. Add any new package you need to the list being appended to prelude-packages.
Also, if you want to use any mode that is not available in MELPA or Marmalade, you can simply drop the mode's file in personal folder and Prelude will pick it up while loading. If there are any customizations to that mode, simply create another .el file and add the Emacs Lisp code there.
Prelude recommends to use
(prelude-require-packages '(some-package some-other-package))
if you have several package. Or in case you want to add just one package:
(prelude-require-package 'some-package)
If you want you can still maintain your package list in a variable:
(setq my-packages '(drupal-mode nginx-mode toto-mode)
(prelude-require-package my-packages)
In your .emacs file you could add code like this (very similar to the code in the link you sent) to check if each package is installed and install it if is not:
(dolist (package '(eredis anything erlang elnode))
(unless (package-installed-p package)
(package-install package)))
In answer to your question there's no reason you can't do this after the prelude code has run.
I'm new to Emacs. I found many emacs plugins are released as an .el file. I'm not sure how to install them. Can I just put them in my emacs installation directory?
After placing it, say myplugin.el to your ~/.emacs.d/ directory, add the following in your .emacs file:
(add-to-list 'load-path "~/.emacs.d/")
(load "myplugin.el")
Also, in many cases you would need the following instead of the second line:
(require 'myplugin)
In any case, you should consult the documentation of the package you are trying to install on which one you should use.
If you are unsure where your ~ directory is, you may see it by typing C-x d ~/ and pressing Enter.
As already stated, you'll need the location of the file to be in Emacs' load path.
Read the comments at the top of the file to see if it has any particular installation or usage instructions. Authors often provide this information, and there isn't one single correct way to do it, so it's sensible to look.
Failing that, if the file contains a (provide 'some-name) line (typically at the end of the file), then you would be expected to use (require 'some-name) to load it.
You may also wish to byte-compile the library for speed (but that's a different question).
Many times, an emacs plugin will consist of a directory of elisp files that need to be accessible from the load path. A simple way to ensure that all individual elisp files as well as subdirectories of elisp files are included in the load path and accessible is to do something similar to the following:
Create a directory called ~/.emacs.d/site-lisp.
Install any single elisp files in the ~/.emacs.d/site-lisp directory.
Install any packages that consist of multiple elisp files in a subdirectory under your ~/.emacs.d/site-lisp directory.
Add the following code to your ~/.emacs file to ensure that Emacs "sees" all the elisp files that you have installed:
(add-to-list 'load-path "~/.emacs.d/site-lisp")
(progn (cd "~/.emacs.d/site-lisp")
(normal-top-level-add-subdirs-to-load-path))
This will ensure that all elisp files that are located either in either the ~/.emacs.d/site-lisp directory or in a subdirectory under that directory are accessible.
Some supplementary information:
MATLAB.el comes from http://matlab-emacs.sourceforge.net/
On windows, use the load path that looks like this:
(add-to-list 'load-path' "C:\\Dropbox\\Portable\\emacs\\matlab-emacs")
If you want FULL MATLAB functionality you should use:
;;MATLAB Mode:
(add-to-list 'load-path' "C:\\Dropbox\\Portable\\emacs\\matlab-emacs")
(require 'matlab-load)
if you just want to edit text files:
;;MATLAB Mode:
(add-to-list 'load-path' "C:\\Dropbox\\Portable\\emacs\\matlab-emacs")
(autoload 'matlab-mode "matlab" "Enter MATLAB mode." t)
(setq auto-mode-alist (cons '("\\.m\\'" . matlab-mode) auto-mode-alist))
(autoload 'matlab-shell "matlab" "Interactive MATLAB mode." t)
I'm very new to emacs and I'm using version 23.2 on Windows. I'm trying to get CEDET working, but when I require it in .emacs it fails to find the file:
File error: Cannot open load file
I was able to get cedet working by loading it manually with:
(load "C:/emacs/lisp/cedet/cedet.el")
But I still can't require other files from cedet like semantic-gcc or semantic-ia.
Here's my .emacs file:
(load "C:/emacs/lisp/cedet/cedet.el")
(global-ede-mode t)
(semantic-mode 1)
;(semantic-load-enable-excessive-code-helpers)
(require 'semantic-ia)
(require 'semantic-gcc)
It's like emacs isn't looking for these files in its own path, and I did try
(add-to-list 'load-path "C:/emacs/lisp/cedet")
With a lot of other variations but none worked.
Firstly, you need to find the reason that cedet won't load with a simple (require 'cedet).
Is Emacs installed at c:\emacs? (ie the emacs.exe you are running is c:\emacs\bin\emacs.exe)
Is something setting EMACSLOADPATH externally from Emacs (your environment, or in the registry under HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER /Software/GNU/Emacs?
Is there another installation of an older version of CEDET on your load path?
Has c:\emacs\lisp\subdirs.el been edited to remove the cedet subdirectory?
Once you've solved that, note that the paths were changed when CEDET was merged into Emacs to accommodate old systems that have limitations on file name lengths. But at the same time, the autoloads were improved, so you shouldn't need to explicitly require those files any more. If you still do, the following should work:
(require 'semantic/ia)
(require 'semantic/bovine/gcc)
