I'm trying to install lua-mode into emacs for windows but nothing seems to be working. I've set my HOME environment variable. I've added init.el and lua-mode.el to the HOME\.emacs.d directory. Then I've added the following code to init.el:
(autoload 'lua-mode "lua-mode" "Lua editing mode." t)
(add-to-list 'auto-mode-alist '("\\.lua$" . lua-mode))
(add-to-list 'interpreter-mode-alist '("lua" . lua-mode))
(add-hook 'lua-mode-hook 'turn-on-font-lock)
Nothing is working when I start up emacs and load a .lua file. The major mode is always set to fundamental and there are no other options to change to. What can I do to get this working?
It's possible that your init.el is never read, because you also have a .emacs file (or .emacs.el) in your $HOME directory. You can choose between those three alternatives for Emacs' init file, but only one of them will be read. Traditionally, that's .emacs but some operating systems have problems with that filename syntax.
Also, make sure that you placed init.el in your actual home directory, not a directory called "HOME" or something.
See here for further details on Emacs init files and here for more info on home directories.
If you're not keen on using the init.el variant, here are instruction that should make lua-mode work for you using .emacs:
Start a new Emacs
Type C-x C-f ~/.emacs <ENTER> (C-x means press CTRL, hold it, press x, release - same for C-f)
Insert the following lines:
(add-to-list 'load-path "/path/to/lua-mode-dir")
(autoload 'lua-mode "lua-mode" "Lua editing mode." t)
(add-to-list 'auto-mode-alist '("\\.lua$" . lua-mode))
(add-to-list 'interpreter-mode-alist '("lua" . lua-mode))
(add-hook 'lua-mode-hook 'turn-on-font-lock)
Type C-x C-s to save the buffer to file
Type C-x C-c to close Emacs
Note that in step 3 you have to adjust "/path/to/lua-mode-dir" with the actual path to the directory where you saved the file lua-mode.el on your hard disk.
maybe you need something like (require 'lua-mode) or something like that? Also make sure that the lua-mode file is in a directory in your load-path variable. Something like this before anything else:
(add-to-list 'load-path "/home/dervin/.emacs.d/site-lisp/")
or wherever, and then the require-
The lines look OK. This can depend on a number of things:
The init.el file is not loaded at startup. In face, this is a non-standard name when it comes to Emacs. Emacs tries to load the files ~/.emacs, ~/emacs.el, and ~/.emacs.d/init.el in order, and will load the first one found. To verify that you file has loaded, you could add (message "Loading my init.el") inside it and check the *Messages* buffer.
The directory where you stored the file lua-mode.el is not in the load path. In fact, the ~/.emacs.d directory is not part of the standard load path.

I'm fairly new to emacs. In fact I'm learning the editor and trying to setup something that will replicate "go to a file inside the project" feature known from Code::Blocks or certain plugins of notepad++.
'projectile' fulfills this need, and I installed it through MELPA. Package installed properly, as I can start it with M-x projectile-global-mode and C-c p commands are recognized.
However, if I put it into my .emacs file, Emacs starts with an error:
Symbol's function definition is void: projectile-global-mode
Contents of my .emacs file are as follows:
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
)
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
)
(global-whitespace-mode 1)
(global-linum-mode 1)
(require 'package)
(add-to-list 'package-archives
'("melpa" . "http://melpa.milkbox.net/packages/") t)
(projectile-global-mode 1)
When I try to (require 'projectile) first, I only end up with another error:
'File error: Cannot open load file, projectile'
I'm using Emacs 24.3.1.
How do I put this on autostart properly?
By default, Emacs initializes packages after evaluated init.el. Hence, in a standard setup, packages are not yet available while init is evaluated.
Use (add-hook 'after-init-hook #'projectile-global-mode) to enable Projectile only after packages are initialized, or explicitly initialize packages at the beginning of your init.el with the following code:
(require 'package)
(setq package-enable-at-startup nil) ; To avoid initializing twice
(package-initialize)
You have to load projectile first, e.g. by using this:
(require 'projectile)
(projectile-global-mode)
you can add
'(initial-major-mode (quote projectile-global-mode))
to your .emacs(or init.el or whatever your file is called) file in the custom-set-variable section.
Alternatively, in newer versions of emacs, the menu Options | Customize Emacs | Specific Option you can type 'initial-major-mode' and this will take you to an interface where emacs can customize itself with that setting. just remember to apply and save
I want to solve my “.emacs bankruptcy” issue, and I've gone through
https://help.ubuntu.com/community/EmacsHowto
http://www.emacswiki.org/emacs/DotEmacsBankruptcy
http://www.emacswiki.org/emacs/DotEmacsDotD
http://www.gnu.org/software/emacs/manual/html_node/emacs/Init-File.html
and it is still unclear to me whether the .emacs.d folder is the solution. I.e., whether it will behave just like a normal .d folder, e.g., /etc/profile.d/, where you drop you scripts and they will be picked up by the system auto-magically. Please confirm.
If not, can someone give me a script that does that, or give me a solution please?
Thanks
The essential content of my ~/.emacs file is:
(require 'cl)
(loop for src in (directory-files "~/.emacs.d" 'full-path "[0-9].*\\.el$") do
(let ((byte (concat src "c")))
(when (file-newer-than-file-p src byte)
(byte-compile-file src))
(message "Loading %s.elc" byte)
(load-file byte)))
It loads configuration files from ~/.emacs.d which start with a number. If the source file (extension .el) is newer than the byte-compiled version (extension .elc) then it byte-compiles the source. Afterwards it loads the byte compiled file.
Here's my ~/.emacs:
;; base dirs
(defvar dropbox.d "~/Dropbox/")
(defvar emacs.d (concat dropbox.d "source/site-lisp/"))
;; load path
(add-to-list 'load-path emacs.d)
(defun add-subdirs-to-load-path (dir)
(let ((default-directory dir))
(normal-top-level-add-subdirs-to-load-path)))
(add-subdirs-to-load-path emacs.d)
(load "init")
All my other scripts are loaded by ~/Dropbox/source/site-lisp/init.el
and are themselves located in ~/Dropbox/source/site-lisp.
That's how I have the same config on multiple machines.
And here's how .../site-lisp/hooks.el is loaded from init.el:
(load "hooks")
My init.el is about 100 lines, .emacs about 20 lines.
The rest 8000 lines of scripts are sliced into around 20 files.
~/.emacs.d/ does not work like /etc/profile.d/ or /etc/modules-load.d/ or similar directories, i.e. Emacs does not automatically load any Emacs Lisp file in this directory.
In fact, Emacs explicitly advises against placing Emacs Lisp libraries in ~/.emacs.d/. The byte compiler emits a warning if you add ~/.emacs.d/ to the load-path.
Instead, create a new sub-directory, e.g. ~/.emacs.d/lisp. Add this directory to your load-path explicitly, with the following code in init.el:
(add-to-list 'load-path (locate-user-emacs-file "lisp"))
Then, place your Emacs Lisp files in this directory, e.g. ~/.emacs.d/lisp/foo.el, and load them in your init.el:
(load "foo" nil 'no-message)
The best approach to avoid the dreaded .emacs bankruptcy is to actually avoid large customizations! Most notably, try to avoid any custom functions and commands.
Instead, try to a find an ELPA package that comes closest to what you want, and either try to get used to it, or customize it to your needs. If you don't find any, first try to write your own and distribute it on Github, Marmalade or MELPA.
Don't be afraid of maintaining a package in the public. You'll have to maintain your customization anyway, whether in your init.el or not, so you can just as well let other Emacs users help you with this job.
Adding code to your init.el should be your very last resort!
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 downloaded Auto-Complete from here: http://github.com/m2ym/auto-complete/downloads, I placed all the files from the .zip file in my load-path (C:\...Application Data\.emacs.d\plugins\auto-complete-1.0), and added the following to my .emacs:
;; load auto complete
(add-to-list 'load-path "~/.emacs.d/plugins/auto-complete-1.0")
(require 'auto-complete)
(global-auto-complete-mode t)
but an error message shows up:
.emacs:53:1:Error: Cannot open load file: auto-complete
I use a trailing '/' with directory names (as per file-name-as-directory). e.g.:
(add-to-list 'load-path (file-name-as-directory
(expand-file-name "~/.emacs.d/plugins/auto-complete-1.0")))
I rather doubt that's actually an issue, though.
Are your permissions appropriate for those files and directories?
Are you sure that ~ really expands to C:\...Application Data? Do C-x d ~ RET to be sure.
I am totally new to emacs and is starting to learn how to use it effectively.
The first thing I wanna use is the svn mode.
I downloaded psvn.el and put it in the ~/.emacs.d directory
Then following the instruction in the comment part of the psvn.el file, I put this line
(require 'psvn)
Into the .emacs file
This is my current .emacs file
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(inhibit-startup-screen t))
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
)
(require 'psvn)
Now when I starts emacs, I got this error message:
An error has occurred while loading `/home/akong/.emacs':
File error: "Cannot open load file", "psvn"
To ensure normal operation, you should investigate the cause
of the error in your initialization file and remove it. Start
Emacs with the `--debug-init' option to view a complete error
backtrace
Did I put the psvn.el in a wrong location?
I am using cygwin + WinXP
This is because Emacs cannot find any file providing psvn on its load-path.
In your shell:
mkdir -p ~/.emacs.d # Make the directory unless it exists
mv /some/path/psvn.el ~/.emacs.d/ # Move psvn.el into that directory
In your Emacs init file (often ~/.emacs):
(add-to-list 'load-path "~/.emacs.d") ; Add this directory to Emacs' load path
(require 'psvn) ; Load psvn
EDIT: I just realized that you are on Windows XP. I'm not sure how Cygwin will handle all of this, but the procedure is pretty much the same outside of Cygwin, just remember that ~ is %APPDATA% on Windows XP, so .emacs.d and .emacs should both be in that directory.
I guess you have problem finding your home directory on Windows? Try C-x d ~ RETURN (run dired on your home directory) to see where you home directory is, then do what the other answers say: put psvn.el in .emacs.d and add ~/.emacs.d in your load-path
First thing you're going to want to do is add .emacs.d to your load path so it knows where to look. Generally most people store .el plugins in ~/.emacs.d/site-lisp so i do this:
;; >>> Configure Load Path <<< ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(setq emacs-config-path "~/.emacs.d/")
(setq base-lisp-path "~/.emacs.d/site-lisp/")
(setq site-lisp-path (concat emacs-config-path "/site-lisp"))
(defun add-path (p)
(add-to-list 'load-path (concat base-lisp-path p)))
;; I should really just do this recursively.
(add-path "")
;; (add-path "some-nested-folder")
Now (require 'psvn) should work out fine.
