In my emacs 24.3, I can't find the AUCTeX package.
If I enter PACKAGE-LIST-PACKAGE,
I find various packages for AUCTeX like "auctex-lua" or
"auto-complete for auctex". However, there is no auctex package that I can install. Why is it gone ?
AUCTeX is available via GNU ELPA, not MELPA.
You can configure multiple repositories, e.g. by using add-to-list instead of setting package-archives directly:
(add-to-list 'package-archives
'("melpa" . "http://melpa.org/packages/") t)
This should keep GNU ELPA in your list of archives, but in case it doesn't you can always add it back. It should look something like
("gnu" . "http://elpa.gnu.org/packages/")
Once you've done this you should be able to install AUCTeX via package.el.
Note that this is likely the one repository that most users should have in their package-archives list. It's the official GNU repository, enabled by default. Of course, feel free to add others as you wish!

I'm trying to install org-checklist for spacemacs but I'm having some difficulties. On the project documentation (https://orgmode.org/worg/org-contrib/org-checklist.html) it says enable the org contrib directory but when I run M-x find-library RET org-contribdir it says the contrib directory is deprecated. When I try installing org-plus-contrib with package-list-packages, nothing happens.
How to untick checkboxes in org-mode for the next cyclic/repetitive task - This stack overflow question says I should download the org-checklist.el file but I can't find it anywhere. If anyone knows how to set up org-checklist or a viable alternative, I'd be really grateful
org-checklist.el is part of org-plus-contrib. You should be able to install it with package-manager: it is available from orgmode.org, so you have to add (add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t) to your list of archives.
Starting from emacs -q I was able to install it after evaluating these lines:
(require 'package)
(add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)
in the *scratch* buffer. Invoking package-list-packages showed org-plus-conrib as an available package and ix installed it (after I confirmed that I wanted to install it).
I was then able to load org-checklist with M-x load-library RET org-checklist RET.
Alternatively, you can just download the file from here and save it in some place that is found in your emacs's load-path, then say (require 'org-checklist).
Hope this helps.
I've read in a lot of places such as the WikEmacs (http://wikemacs.org/wiki/Evil) that Emacs24 already came with support for Evil mode, no need to install it via el-get. But I can't seem to understand how do I activate it.
I tried just adding the
(require 'evil)
(evil-mode 1)
lines to my .emacs but it can't seem to work, how do you guys use the built-in evil mode on emacs24? without cloning git repositories, etc.
The statement on WikEmacs is false; evil-mode is not included in Emacs 24. (As it's a wiki, I just edited the page and removed that text.)
There are many ways to install evil-mode. I'd suggest activating the MELPA package repository by adding the following to your .emacs file:
(require 'package)
(add-to-list 'package-archives
'("melpa" . "http://melpa.org/packages/") t)
(package-initialize)
Then type M-x list-packages, find evil in the list, and install it.
I’m been wanting to install a number of new packages for Emacs. mmm-mode, multi-web-mode, and smart-tab-mode are a few examples. But I don’t seem to be able to find them when I run
M-x package-list-packages
I have this in my .emacs file:
(require 'package)
(add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/"))
(package-initialize)
And when I run package-list-packages I can see that it contacts all those different hosts. I use C-s to search for them, they aren’t there. What am I doing wrong?
My Emacs version is displayed as: Version 24.2 (9.0)
URL for Melpa was too short: it should be http://melpa.milkbox.net/packages/
You've mixed up the order. It goes like this:
(package-initialize)
(add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/packages/"))
The ELPA/package system is a relatively new addition to Emacs. It is far from the case that all libraries are available as packages, but similarly it is not necessary for a library to be packaged in order to use it with Emacs.
If a library you wish to use is unavailable through any of the package repositories, simply follow the installation/usage instructions which (generally) can be found in the accompanying documentation for the library (either in the .el file's commentary, or as a separate file).
(You will at minimum need to ensure that the files are located in a directory which is in Emacs' load-path, but the exact details thereafter will vary depending upon the purpose of the library in question.)
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 was following the guide and information from A gentle tutorial to Emacs/Swank/Paredit for Clojure
However after opening elpa and installing clojure-mode, slime and paredit. I restarted emacs and then attempted to use M-x slime however it continually says no match . What am I doing wrong?
I then tried to install clojure-mode from marmalade http://marmalade-repo.org/packages I byte-compiled package el and then added
(add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/")) to my.emacs. However marmalade errors with
Symbol's value as variable is void: package-archives .
Unsure exactly what I am doing wrong I am on windows7 using emacs 23.3. I have clojure installed to c:/clojure.
Any help appreciated.
My init.el has both (require 'package) and (package-initialize). It's not very big, it looks like this:
(require 'package)
;; Add the original Emacs Lisp Package Archive
(add-to-list 'package-archives
'("elpa" . "http://tromey.com/elpa/"))
;; Add the user-contributed repository
(add-to-list 'package-archives
'("marmalade" . "http://marmalade-repo.org/packages/"))
(package-initialize)
I'm on emacs 24 (a development build) on Windows 7. I had trouble getting emacs 23 to work with packages too, it was easier for me to just upgrade.
By the way, I noticed that if I set a HOME environment variable, emacs looks there for the .emacs.d directory (instead of in %USER_PROFILE%\AppData\Roaming).
Download package.el (don't follow the instructions on the ELPA site, just download the package.el provided on marmalade's site).
Put package.el in your .emacs.d directory (~/.emacs.d/).
Add the following to your .emacs file (~/.emacs):
;;Load path to my packages
(add-to-list 'load-path "~/.emacs.d/")
;;Load ELPA (the package.el you downloaded from marmalade)
(require 'package)
;;Load Marmalade (the code found on marmalade's welcome page)
(add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))
That's it! I really hope this helps.
EDIT: Sorry, I forgot to mention that you need to add (package-initialize) at the end of the code I provided. If you don't add this line, the packages will install, but won't load.
I think, that you need to put
(require 'package)
before 'add-to-list'
P.S. and add following call after 'add-to-list'
(package-initialize)
this command will load installed packages and activate them
P.P.S. '(require 'package)' maybe not needed, but I'm personally not using 'package.el'
It seems to me you're missing either (require 'package) or (package-initialize). You can check out my setup here - I'm using both marmalade and clojure-mode on Windows 7 and it works like a charm.
Do not know it is same problem, I faced when I were trying to use quicklisp's swank/slime
Finally I found that few /contrib/*.el packages were dependent on each other
if A's dependency package is B, if B is not byte-compiled than A will not compile
when you do
(require 'A)
it will throw
Symbol's variable value is void: A
So ensure you compile each package than try require.
