In coffee-mode RET is bound to coffee-newline-and-indent which works fine.
I also use evil-mode to have Vim emulation. evil-mode uses the standard newline-and-indent so the indentation is not correct for some vim commands such as o or O.
What would be the best way to rebind newline-and-indent to coffee-newline-and-indent ?
I'm still a newbie in ELisp and tried the line below but it doesn't work.
(add-hook 'coffee-mode-hook
(lambda ()
(setq newline-and-indent '(funcall coffee-newline-and-indent))))
Here's my attempt. It should work, but I don't really like it.
(add-hook
'coffee-mode-hook
(lambda ()
(defalias
'newline-and-indent
(lambda()
(interactive)
(if (eq major-mode 'coffee-mode)
(coffee-newline-and-indent)
(delete-horizontal-space t)
(newline)
(indent-according-to-mode))))))
I wish I could use something more elegant that just copying the source
of newline-and-indent, but make-variable-buffer-local doesn't work for this case,
and I couldn't get a deep copy for symbol-function either.
I'd be happy to see a better method.
The standard way to accomplish what you seem to be asking for is
(autoload 'coffee-newline-and-indent "coffee-mode") ; (or whatever)
(define-key evil-mode-map (kbd "RET") 'coffee-newline-and-indent)
EDIT: to enable coffee-newline-and-indent only in coffee-mode:
(define-key evil-mode-map (kbd "RET")
(lambda ()
(interactive)
(if (eq major-mode 'coffee-mode)
(coffee-newline-and-indent)
(newline-and-indent))))
Try the following:
(define-key evil-mode-map (kbd "RET") nil)
I know it looks overly simple, but if evil-mode works the way I think it does then it should work.
This will wipe the ret key from your evil-mode-map, which will let the binding of coffee-mode-map shine through.
In non-coffee buffers, the ret key will still work, because it's still bind in the global map.
I found the solution.
Evil-mode actually uses coffee-indent-line. The problem comes from coffee-indent-line which doesn't indent correctly. Evil-mode works correctly after patching it to behave like coffee-newline-and-indent:
(defadvice coffee-indent-line (after wants-indent activate)
(let ((tabs-needed (- (/ (coffee-previous-indent) coffee-tab-width) 1)))
(when (> tabs-needed 0)
(insert-tab tabs-needed)))
(when(coffee-line-wants-indent)
(insert-tab)))
if you want to remap a func, but only if some major mode is active
- create a func which defines an alias
and run the func (A)
- another func (B) calls (A)
- finally, a major mode can advice the func A to set the correct
func. It has to test major mode.
let's say A is define-my-indent-f
then it says (defalias my-indent 'newline-and-indent)
the func b runs A then run command my-indent.
finally coffe mode does defadice A to say
(if eq major mode coffee defalais my-indent 'coffe-newline-and-indent)
of course this is super heavy to define, but then
- each major mode can add its piece
- only loaded major mode will advice
Is there a best practice around lazily loading modes when encountering a relevant file extension?
At this point I have roughly 25 different Emacs modes installed, and startup has become slow. For example, although it's great to have clojure-mode at the ready, I rarely use it, and I want to avoid loading it at all unless I open a file with extension .clj. Such a "lazy require" functionality seems like the right way do mode configuration in general..
I found nothing online, so I've taken a crack at it myself.
Instead of:
(require 'clojure-mode)
(require 'tpl-mode)
I have this:
(defun lazy-require (ext mode)
(add-hook
'find-file-hook
`(lambda ()
(when (and (stringp buffer-file-name)
(string-match (concat "\\." ,ext "\\'") buffer-file-name))
(require (quote ,mode))
(,mode)))))
(lazy-require "soy" 'soy-mode)
(lazy-require "tpl" 'tpl-mode)
This seems to work (I'm an elisp newbie so comments are welcome!), but I'm unnerved about finding nothing written about this topic online. Is this a reasonable approach?
The facility you want is called autoloading. The clojure-mode source file, clojure-mode.el, includes a comment for how to arrange this:
;; Add these lines to your .emacs:
;; (autoload 'clojure-mode "clojure-mode" "A major mode for Clojure" t)
;; (add-to-list 'auto-mode-alist '("\\.clj$" . clojure-mode))
This is one way,
(provide 'my-slime)
(eval-after-load "slime"
'(progn
(setq slime-lisp-implementations
'((sbcl ("/usr/bin/sbcl"))
(clisp ("/usr/bin/clisp")))

C-x s uses diff to show changes. How can I use ediff instead?
I can see a couple of approaches to doing this. The first is to replace the save-some-buffers-action-alist variable with modified code, which is more straightforward. The second is to advise save-some-buffers and redefine the functions called by those actions, but that's a bit trickier.
I tried it both ways, and I think this is the best option:
;; Use ediff instead of diff in `save-some-buffers'
(eval-after-load "files"
'(progn
(setcdr (assq ?d save-some-buffers-action-alist)
`(,(lambda (buf)
(if (null (buffer-file-name buf))
(message "Not applicable: no file")
(add-hook 'ediff-after-quit-hook-internal
'my-save-some-buffers-with-ediff-quit t)
(save-excursion
(set-buffer buf)
(let ((enable-recursive-minibuffers t))
(ediff-current-file)
(recursive-edit))))
;; Return nil to ask about BUF again.
nil)
,(purecopy "view changes in this buffer")))
(defun my-save-some-buffers-with-ediff-quit ()
"Remove ourselves from the ediff quit hook, and
return to the save-some-buffers minibuffer prompt."
(remove-hook 'ediff-after-quit-hook-internal
'my-save-some-buffers-with-ediff-quit)
(exit-recursive-edit))))
My attempt at using advice is flawed (it breaks the C-r behaviour which also calls view-buffer, which caused me to reconsider using advice for this purpose), but FWIW:
(defadvice save-some-buffers (around my-save-some-buffers-with-ediff)
"Use ediff instead of diff."
(require 'cl)
(flet ((view-buffer (&rest) nil)
(diff-buffer-with-file
(buf)
(add-hook 'ediff-after-quit-hook-internal
'my-save-some-buffers-with-ediff-quit t)
(save-excursion
(set-buffer buf)
(ediff-current-file))))
(let ((enable-recursive-minibuffers t))
ad-do-it)))
(ad-activate 'save-some-buffers)
(defun my-save-some-buffers-with-ediff-quit ()
"Remove ourselves from the ediff quit hook, and
return to the save-some-buffers minibuffer prompt."
(remove-hook 'ediff-after-quit-hook-internal
'my-save-some-buffers-with-ediff-quit)
(exit-recursive-edit))
The variable diff-command is customizable, says the documentation. However, remember that it points to an external program, and not an elisp function. ediff is an elisp function that is in ediff.el. You might have to edit diff.el to (require 'ediff) and then tweak here and there in diff.el to see that you break nothing else.
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))))

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:
Inserts date in ISO 8601 format:
(defun insertdate ()
(interactive)
(insert (format-time-string "%Y-%m-%d")))
(global-set-key [(f5)] 'insertdate)

(defun createclass ()
(interactive)

(insert
"/**
* " classname".h
*
* Author: Your Mom
* Modified: " (format-time-string "%Y-%m-%d") "
* Licence: GNU GPL
*/
#ifndef "(upcase classname)"
#define "(upcase classname)"
class " classname "
{
public:
"classname"();
~"classname"();
private:
};
#endif
"))
Automatically create closing parentheses:
(setq skeleton-pair t)
(setq skeleton-pair-on-word t)
(global-set-key (kbd "[") 'skeleton-pair-insert-maybe)
(global-set-key (kbd "(") 'skeleton-pair-insert-maybe)

(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.

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)
)
)
