I like VIM idea of text objects, so I installed EVIL (a Emacs plugin to emulate VIM features). But I'd like «insert» mode to leave Emacs keybindings unchanged (except perhaps Escape which is to switch into «normal» mode). Any way to achieve this?
By the way: ATM «insert» mode have a mixed set of hotkeys, which isn't very comfortable either way. E.g. the «M-b» works as in Emacs, but the «C-o» works as in VIM.
In the #emacs IRC channel I was told that someone already solved a similar problem. Here's the modified version I use:
(require 'evil)
;; remove all keybindings from insert-state keymap
(setcdr evil-insert-state-map nil)
;; but [escape] should switch back to normal state
(define-key evil-insert-state-map [escape] 'evil-normal-state)
(define-key evil-normal-state-map (kbd "C-u") 'evil-scroll-up)
(define-key evil-normal-state-map (kbd "[ m") 'beginning-of-defun)
(define-key evil-normal-state-map (kbd "] m") 'end-of-defun)
(define-key evil-normal-state-map (kbd "k") 'evil-previous-visual-line)
(define-key evil-normal-state-map (kbd "j") 'evil-next-visual-line)
(evil-mode t)
(setq evil-jumps-cross-buffers nil) ;; for C-o and C-i to not cross buffers
(provide 'emvil)
The (provide 'emvil) is to allow require 'ing it in the configuration. I also found it useful to jump-to-definition in the next split screen unless the definition is in the buffer I'm currently in. Here's the code:
(defun evil-goto-definition-next-split ()
"If there's a free split, goto definition in this split,
otherwise use current one (except when a definition in the
current split)"
(interactive)
(let ((origin-spl (selected-window))
(origin-buf (current-buffer)))
(evil-goto-definition)
(when (and (eq origin-spl (selected-window)) ;; otherwise it's done
(not (eq origin-buf (current-buffer)))) ;; otherwise either definition not found, or
;; it's in the same buffer
(let ((defin-buf (current-buffer))
(defin-point (point)))
(switch-to-buffer origin-buf)
(other-window 1)
(switch-to-buffer defin-buf)
(goto-char defin-point)
))
))
(define-key evil-normal-state-map (kbd "g d") 'evil-goto-definition-next-split)
I'm completely new to both Lisp and Emacs. In Emacs, when coding in Java for example, I want to be able to type "{" then hit "ENTER" and have the next line be ready for whatever is nested in the braces. For example, if I have the following line:
public void method()
and I type "{" then hit return I should get this:
public void method() {
// indentation applied, no additional tabbing necessary
}
I'm already able to insert by pairs, for example, typing "{" gives "{}" with my cursor between the braces. I did this by adding these lines to the emacs init file:
;; insert by pairs (parens, quotes, brackets, braces)
(defun insert-pair (leftChar rightChar)
(if (region-active-p)
(let (
(p1 (region-beginning))
(p2 (region-end))
)
(goto-char p2)
(insert rightChar)
(goto-char p1)
(insert leftChar)
(goto-char (+ p2 2))
)
(progn
(insert leftChar rightChar)
(backward-char 1) ) )
)
(defun insert-pair-brace () (interactive) (insert-pair "{" "}") )
(global-set-key (kbd "{") 'insert-pair-brace)
To get the auto-nesting I described above, I added these lines:
;; automatically nest next line
(defun auto-nest ()
(insert "\n\n")
(backward-char 1)
(insert "\t")
)
(defun auto-nest-brace () (interactive) (auto-nest) )
(global-set-key (kbd "{ RET") 'auto-nest-brace)
When I start up Emacs, however, I get this message:
error: Key sequence { RET starts with non-prefix key {
What am I doing wrong, and what can I do to fix it? I don't want to use a different key combination to do this. There are a lot of text editors in which this auto-nesting is standard, and it should be easy enough to code up in ELisp.
It's great that you are trying to add this functionality to Emacs yourself, but there's no need to reinvent the wheel here. Emacs already has a command for the purpose of auto-indenting; it's called newline-and-indent. It is bound to C-j by default, but you can rebind it to RET
globally:
(global-set-key (kbd "RET") 'newline-and-indent)
for a specific mode only:
(require 'cc-mode)
(define-key java-mode-map (kbd "RET") 'newline-and-indent)
java-mode-map is defined in cc-mode.el and not available by default, that's why you have to require cc-mode before you can modify java-mode-map.
Note that newline-and-indent indents according to major mode. That is, if you're e.g. in java-mode and press RET in some random location that's not meaningful w/r/t Java syntax, it won't insert additional whitespace at the beginning of the new line.
To read all there is to know about newline-and-indent do
C-h f newline-and-indent RET
I have something similar in my emacs config which I have been using for a while. It calls 'newline-and-indent twice then moves the point one line up before indenting correctly. Here is the snippet of code to do this from my config file:
;; auto indent on opening brace
(require 'cc-mode)
(defun av/auto-indent-method ()
"Automatically indent a method by adding two newlines.
Puts point in the middle line as well as indent it by correct amount."
(interactive)
(newline-and-indent)
(newline-and-indent)
(forward-line -1)
(c-indent-line-or-region))
(defun av/auto-indent-method-maybe ()
"Check if point is at a closing brace then auto indent."
(interactive)
(let ((char-at-point (char-after (point))))
(if (char-equal ?} char-at-point)
(av/auto-indent-method)
(newline-and-indent))))
(define-key java-mode-map (kbd "RET") 'av/auto-indent-method-maybe)
Pretty straightforward as you can see. Hopefully it will work for you. I have not used it in any other modes except java.
You want a combination of auto pairs (or alternatives) plus auto indentation. Check out the emacswiki on the former: http://www.emacswiki.org/emacs/AutoPairs
And on the latter:
http://www.emacswiki.org/emacs/AutoIndentation
Continuing my process of migrating the latest & greatest Emacs 23.2, I hit another unpleasant surprise: dynamic expansion in minibuffer no longer works!
By "dynamic expansion in the minibuffer" I mean the feature that lets you blindly hit the spacebar to complete filenames, variables, etc.
I also invoked 'Emacs -Q' (to rule out any .emacs artifacts) and the problem exists not only with Emacs 23.2 on Windows XP, but even with Emacs 22.1 on Ubuntu.
Something has changed in Emacs' default behavior, but what is it?
From the (22.1) NEWS file:
** When Emacs prompts for file names, SPC no longer completes the file name.
This is so filenames with embedded spaces could be input without the
need to quote the space with a C-q. The underlying changes in the
keymaps that are active in the minibuffer are described below under
"New keymaps for typing file names".
If you want the old behavior back, add these two key bindings to your
~/.emacs init file:
(define-key minibuffer-local-filename-completion-map
" " 'minibuffer-complete-word)
(define-key minibuffer-local-must-match-filename-map
" " 'minibuffer-complete-word)
The posted solution works, but will break once we get to Emacs v24 and later. I would recommend instead tying your define-key calls to the presence of the new maps, as so:
(if (boundp 'minibuffer-local-filename-completion-map)
(define-key minibuffer-local-filename-completion-map " " 'minibuffer-complete-word))
(if (boundp 'minibuffer-local-must-match-filename-map)
(define-key minibuffer-local-must-match-filename-map " " 'minibuffer-complete-word))
This should work correctly for all Emacs versions.
Answering my 2nd question (in the comment):
(defmacro GNUEmacs23 (&rest body)
(list 'if (string-match "GNU Emacs 23" (version))
(cons 'progn body)))
(defmacro GNUEmacs22 (&rest body)
(list 'if (string-match "GNU Emacs 22" (version))
(cons 'progn body)))
(GNUEmacs22
(define-key minibuffer-local-filename-completion-map " " 'minibuffer-complete-word)
(define-key minibuffer-local-must-match-filename-map " " 'minibuffer-complete-word)
)
(GNUEmacs23
(define-key minibuffer-local-filename-completion-map " " 'minibuffer-complete-word)
(define-key minibuffer-local-must-match-filename-map " " 'minibuffer-complete-word)
)
If you come up with a more elegant solution, that would be great, but the above works for me (for now).
Locked. This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions.
I've switched computers a few times recently, and somewhere along the way I lost my .emacs. I'm trying to build it up again, but while I'm at it, I thought I'd pick up other good configurations that other people use.
So, if you use Emacs, what's in your .emacs?
Mine is pretty barren right now, containing only:
Global font-lock-mode! (global-font-lock-mode 1)
My personal preferences with respect to indentation, tabs, and spaces.
Use cperl-mode instead of perl-mode.
A shortcut for compilation.
What do you think is useful?
Use the ultimate dotfiles site. Add your '.emacs' here. Read the '.emacs' of others.
My favorite snippet. The ultimate in Emacs eye candy:
;; real lisp hackers use the lambda character
;; courtesy of stefan monnier on c.l.l
(defun sm-lambda-mode-hook ()
(font-lock-add-keywords
nil `(("\\<lambda\\>"
(0 (progn (compose-region (match-beginning 0) (match-end 0)
,(make-char 'greek-iso8859-7 107))
nil))))))
(add-hook 'emacs-lisp-mode-hook 'sm-lambda-mode-hook)
(add-hook 'lisp-interactive-mode-hook 'sm-lamba-mode-hook)
(add-hook 'scheme-mode-hook 'sm-lambda-mode-hook)
So you see i.e. the following when editing lisp/scheme:
(global-set-key "^Cr" '(λ () (interactive) (revert-buffer t t nil)))
I have this to change yes or no prompt to y or n prompts:
(fset 'yes-or-no-p 'y-or-n-p)
I have these to start Emacs without so much "fanfare" which I got from this question.
(setq inhibit-startup-echo-area-message t)
(setq inhibit-startup-message t)
And Steve Yegge's function to rename a file that you're editing along with its corresponding buffer:
(defun rename-file-and-buffer (new-name)
"Renames both current buffer and file it's visiting to NEW-NAME."
(interactive "sNew name: ")
(let ((name (buffer-name))
(filename (buffer-file-name)))
(if (not filename)
(message "Buffer '%s' is not visiting a file!" name)
(if (get-buffer new-name)
(message "A buffer named '%s' already exists!" new-name)
(progn
(rename-file name new-name 1)
(rename-buffer new-name)
(set-visited-file-name new-name)
(set-buffer-modified-p nil))))))
One thing that can prove very useful: Before it gets too big, try to split it into multiple files for various tasks: My .emacs just sets my load-path and the loads a bunch of files - I've got all my mode-specific settings in mode-configs.el, keybindings in keys.el, et cetera
My .emacs is only 127 lines, here are the most useful little snippets:
;; keep backup files neatly out of the way in .~/
(setq backup-directory-alist '(("." . ".~")))
This makes the *~ files which I find clutter up the directory go into a special directory, in this case .~
;; uniquify changes conflicting buffer names from file<2> etc
(require 'uniquify)
(setq uniquify-buffer-name-style 'reverse)
(setq uniquify-separator "/")
(setq uniquify-after-kill-buffer-p t) ; rename after killing uniquified
(setq uniquify-ignore-buffers-re "^\\*") ; don't muck with special buffers
This sets up uniquify which changes those ugly file<2> etc. buffer names you get when multiple files have the same name into a much neater unambiguous name using as much of the whole path of the file as it has to.
That's about it... the rest is pretty standard stuff that I'm sure everyone knows about.
This is not the whole kit and kaboodle, but it is some of the more useful snippets I've gathered:
(defadvice show-paren-function (after show-matching-paren-offscreen
activate)
"If the matching paren is offscreen, show the matching line in the
echo area. Has no effect if the character before point is not of
the syntax class ')'."
(interactive)
(let ((matching-text nil))
;; Only call `blink-matching-open' if the character before point
;; is a close parentheses type character. Otherwise, there's not
;; really any point, and `blink-matching-open' would just echo
;; "Mismatched parentheses", which gets really annoying.
(if (char-equal (char-syntax (char-before (point))) ?\))
(setq matching-text (blink-matching-open)))
(if (not (null matching-text))
(message matching-text))))

This block is the most important for me:

(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)
I've never been clear on the difference between those, though. Cargo cult, I guess...
I try to keep my .emacs organized. The configuration will always be a work in progress, but I'm starting to be satisfied with the overall structure.
All stuff is under ~/.elisp, a directory that is under version control (I use git, if that's of interest). ~/.emacs simply points to ~/.elisp/dotemacs which itself just loads ~/.elisp/cfg/init. That file in turn imports various configuration files via require. This means that the configuration files need to behave like modes: they import stuff they depend on and they provide themselves at the end of the file, e.g. (provide 'my-ibuffer-cfg). I prefix all identifiers that are defined in my configuration with my-.
I organize the configuration in respect to modes/subjects/tasks, not by their technical implications, e.g. I don't have a separate config file in which all keybindings or faces are defined.
My init.el defines the following hook to make sure that Emacs recompiles configuration files whenever saved (compiled Elisp loads a lot faster but I don't want to do this step manually):
;; byte compile config file if changed
(add-hook 'after-save-hook
'(lambda ()
(when (string-match
(concat (expand-file-name "~/.elisp/cfg/") ".*\.el$")
buffer-file-name)
(byte-compile-file buffer-file-name))))
This is the directory structure for ~/.elisp:
~/.elisp/todo.org: Org-mode file in which I keep track of stuff that still needs to be done (+ wish list items).
~/.elisp/dotemacs: Symlink target for ~/.emacs, loads ~/.elisp/cfg/init.
~/.elisp/cfg: My own configuration files.
~/.elisp/modes: Modes that consist only of a single file.
~/.elisp/packages: Sophisticated modes with lisp, documentation and probably resource files.
I use GNU Emacs, that version does not have real support for packages. Therefore I organize them manually, usually like this:
~/.elisp/packages/foobar-0.1.3 is the root directory for the package. Subdirectory lisp holds all the lisp files and info is where the documentation goes. ~/.elisp/packages/foobar is a symlink that points to the currently used version of the package so that I don't need to change my configuration files when I update something. For some packages I keep an ~/.elisp/packages/foobar.installation file around in which I keep notes about the installation process. For performance reasons I compile all elisp files in newly installed packages, should this not be the case by default.
Here's a couple of my own stuff:

(defun insertdate ()
(interactive)
(insert (format-time-string "%Y-%m-%d")))
(global-set-key [(f5)] 'insertdate)

(insert
"/**

*
* Author: Your Mom

*/
#ifndef "(upcase classname)"
#define "(upcase classname)"

{

"classname"();
~"classname"();

#endif
"))

(global-set-key (kbd "(") 'skeleton-pair-insert-maybe)

i use paredit for easy (e)lisp handling and ido-mode minibuffer completions.
It's hard to answer this question, because everyone uses Emacs for very different purposes.
Further more, a better practice may be to KISS your dotemacs. Since the Easy Customization Interface is widely supported amongst Emacs' modes, you should store all your customization in your custom-file (which may be a separate place in your dotemacs), and for the dotemacs, put in it only load path settings, package requires, hooks, and key bindings. Once you start using Emacs Starter Kit, a whole useful bunch of settings may removed from your dotemacs, too.
See EmacsWiki's DotEmacs category. It provides lots of links to pages addressing this question.

One line to load my emacs init files
Of course, the "emacs init files" are quite numerous, one per specific thing, loaded in a deterministic order.
emacs-starter-kit as a base, then I've added.. vimpulse.el, whitespace.el, yasnippet, textmate.el and newsticker.el.
In my ~/.emacs.d/$USERNAME.el (dbr.el) file:
(add-to-list 'load-path (concat dotfiles-dir "/vendor/"))
;; Snippets
(add-to-list 'load-path "~/.emacs.d/vendor/yasnippet/")
(require 'yasnippet)
(yas/initialize)
(yas/load-directory "~/.emacs.d/vendor/yasnippet/snippets")
;; TextMate module
(require 'textmate)
(textmate-mode 'on)
;; Whitespace module
(require 'whitespace)
(add-hook 'ruby-mode-hook 'whitespace-mode)
(add-hook 'python-mode-hook 'whitespace-mode)
;; Misc
(flyspell-mode 'on)
(setq viper-mode t)
(require 'viper)
(require 'vimpulse)
;; IM
(eval-after-load 'rcirc '(require 'rcirc-color))
(setq rcirc-default-nick "_dbr")
(setq rcirc-default-user-name "_dbr")
(setq rcirc-default-user-full-name "_dbr")

Always save my config in svn http://my-trac.assembla.com/ez-conf/browser/emacs.d
After reading this, I figured it would be good to have a simple site just for the best .emacs modifications. Feel free to post and vote on them here:

I'm new to emacs, in my .emacs file there are
indentation configuration
color theme
php mode, coffee mode and js2 mode
ido mode
FWIW, my .emacs is here:
http://svn.red-bean.com/repos/kfogel/trunk/.emacs
lots of stuff: https://github.com/tavisrudd/emacs.d
el-get has made managing it and dependencies a lot easier: https://github.com/tavisrudd/emacs.d/blob/master/dss-init-el-get.el
For Scala coders
;; Load the ensime lisp code... http://github.com/aemoncannon/ensime
(add-to-list 'load-path "ENSIME_ROOT/elisp/")
(require 'ensime)
;; This step causes the ensime-mode to be started whenever ;; scala-mode is started for a buffer. You may have to customize this step ;; if you're not using the standard scala mode.
(add-hook 'scala-mode-hook 'ensime-scala-mode-hook)
;; MINI HOWTO: ;; Open .scala file. M-x ensime (once per project)
My emacs configuration has grown up pretty big over the years and I have lot of useful stuff for me there but if I have two functions it probably would have been those ones.
Define C-x UP and C-x DOWN to move the current line or down keeping the cursor at the right place :
;Down/UP the current line
(global-set-key '[(control x) (up)] 'my-up-line)
(global-set-key '[(control x) (down)] 'my-down-line)
(defun my-down-line()
(interactive)
(let ((col (current-column)))
(forward-line 1)
(transpose-lines 1)
(forward-line -1)
(forward-char col)
)
)
(defun my-up-line()
(interactive)
(let ((col (current-column)))
(transpose-lines 1)
(forward-line -2)
(forward-char col)
)
)
