I am working on C code.
I have a problem same as that in this question.
The solution there is to use spaces instead of tabs. But I'm trying/I'd prefer to use Smart Tabs Mode.
I've tried enabling and disabling both "c-tab-always-indent" and "indent-tabs-mode" (in cc-mode-hook).
The problem I see is that in some parts of the code a nested loop generates two Tabs, as expected(?). But in some cases, it generates only one tab and four spaces, while in other cases it generates only one tab, something like below:
function_name
open brace here
...code indented by 4 spaces (though I want a tab)>
open_brace
_tab_ code under condition
_4spc_ close_brace
some more 4 space aligned code
_tab_ open_brace
_tab+4spc_ code under some block
_tab_ close_brace
some more 4 space aligned code
_tab_ open_brace
_2 tabs_ code aligned as I prefer with two tabs
_tab_ close_brace
Can someone help me with getting the last style in the whole code?
My .emacs file is here (I use a few packages, like cscope and hide-show, but I don't think that should cause problems):

I am novice emacs user, and currently i am trying to set up work environment for python. I am using rope, but has come across the following: although rope's "Find occurences" command works fine, its result are put in a modeless buffer, and to access them i must copy file names.
Buffer contents are here
As far as i can tell, closes functionality to what i want (that is, opening a file on a given line after clicking on it or pressing RET) is provided by compilation-mode. However, as things are, enabling compilation-mode only causes highlighting of the filenames.
If i undestand correctly, to process lines i need to provide items into compilation-error-regexp-alist, like it is done in following snippet (from emacs wiki
(require 'compile)
(let ((symbol 'compilation-ledger)
(pattern '("^Error: \"\\([^\"\n]+?\\)\", line \\([0-9]+\\):" 1 2)))
(cond ((eval-when-compile (boundp 'compilation-error-regexp-systems-list))
;; xemacs21
(add-to-list 'compilation-error-regexp-alist-alist
(list symbol pattern))
(compilation-build-compilation-error-regexp-alist))
((eval-when-compile (boundp 'compilation-error-regexp-alist-alist))
;; emacs22 up
(add-to-list 'compilation-error-regexp-alist symbol)
(add-to-list 'compilation-error-regexp-alist-alist
(cons symbol pattern)))
(t
;; emacs21
(add-to-list 'compilation-error-regexp-alist pattern))))
How should i modify it to make it work with my buffer?
Are there better/quicker alternatives?
Generally, the quickest way to open a file when its name is displayed in a buffer is
M-x ffap
(short for M-x find-file-at-point)
If you want to open the file automatically, you could define your own function:
(defun open-file-at-point ()
(interactive)
(let ((file (ffap-file-at-point)))
(if file
(find-file file)
(error "No file at point"))))
and maybe bind it to a key with
(global-set-key (kbd "C-<return>") 'open-file-at-point)
If you want to use compilation-mode, you will have to add a matching regexp to compilation-error-regexp-alist(-alist). For your example, the following seems to work:
(add-to-list
'compilation-error-regexp-alist
'python-file-name)
(add-to-list
'compilation-error-regexp-alist-alist
(list
'python-file-name
(concat "\\(?1:.*?\\)" ;; file name
" : " ;; seperator
"\\(?2:[[:digit:]]+\\)") ;; line number
1 2)) ;; subexpr 1 is the file name, subexp 2 is the line number
I indicate my muse-mode files (usually named with .txt suffix) as being muse-mode by starting them with a "#title". To do this, I have
;; muse-mode on *.txt files, if a #title or sect. header is on top 4 lines
(add-hook 'text-mode-hook
(lambda ()
(unless (or (eq major-mode 'muse-mode)
(not (stringp buffer-file-truename)))
(when (equal (file-name-extension buffer-file-truename) "txt")
(save-excursion
(goto-line 5)
(if (re-search-backward "\* [A-Z][a-z]+.*\\|#title " 1 t)
(muse-mode)))))))
If I also have
(add-to-list 'auto-mode-alist '("\\.txt$" . visual-line-mode))
in the .emacs (following the code above), then muse-mode no longer works. Though if I invoke visual-line-mode with Meta-x from within emacs on a muse file, it doesn't mess things up.
Ideally, I would like to have visual-line-mode working on all .txt files, but without messing up muse. Or else, I would like to start all .txt files in visual-line-mode except when they are muse files.
The variable 'auto-mode-alist chooses the major mode.
visual-line-mode is a minor mode, and by adding it to the 'auto-mode-alist you're making it act like a major mode, which replaces the text-mode you were starting with.
Instead, add turn-on-visual-line-mode-in-txt to the text-mode-hook like so:
(add-hook `text-mode-hook 'turn-on-visual-line-mode)
(defun turn-on-visual-line-mode-in-txt ()
(when (and (buffer-file-name)
(string-match ".txt$" (buffer-file-name)))
(turn-on-visual-line-mode)))
For more information on the differences, read the manual for major and minor modes.
I think #treyJackson identified the problem, but here are some extra comments:
BTW, your use of a text-mode-hook to switch to muse-mode will misbehave in various circumstances (because you first switch to text-mode, then halfway through you activate muse-mode, after which the end of the text-mode activation (usually, not much left to do, but there could be more functions on the text-mode-hook to run) will still be performed). A more robust approach might be to do:
(add-to-list 'auto-mode-alist '("\\.txt\\'" . text-or-muse-mode))
(defun text-or-muse-mode ()
(if (save-excursion
(goto-line 5)
(re-search-backward "\\* [A-Z][a-z]+.*\\|#title " 1 t))
(muse-mode)
(text-mode)))
Of course, you could also use a -*- muse -*- on the first line, or rely on magic-mode-alist instead.
I am facing some strange behavior with file-name completion in emacs. C-x C-f to find file opens up the minibuffer with i:/cygwin/home/rrajagop/StockScreener/working_copy/master_repo/stock_screener/. Hitting a TAB makes it i:/cygwini:/cygwin/home/rrajagop/StockScreener/working_copy/master_repo/stock_screener/. A couple of interesting things I've noticed:
When the minibuffer opens up, i:/cygwin is greyed out and the path seems to start from /home. A C-a (go to begining of line) takes me to /home and not to i:/cygwin. So it looks like something in emacs is parsing the path to start from /home and not from i:/cygwin.
I checked that TAB runs minibuffer-complete from minibuffer.el (by doing a describe-key for TAB), so it looks like minibuffer-complete is doing some translation for cygwin and appending the extra i:/cygwin.
How would I go about figuring this out/fixing it?

I think my answer to your previous question on finding the package loading tramp will help you out here.
you can control tramp by changing the variable tramp-mode.
Side note, you would probably find it useful to use customize to customize emacs.
I did a customize-apropos with tramp and it found the tramp group. Clicking there showed all the ways to configure tramp, including turning it off.
File-name-shadow-mode greys out the c: in the file name..... so when cygwin-mount-substitute-longest-mount-name runs it does no see the c: and adds another
M-x find-file
c:/home/
> a
c:/home/a ; but the c: is greyed
> TAB
c:c:/home/anything
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))))

You can find my configuration (both in html & in tar'ed archive) on my site. It contains lot of settings for different modes
This block is the most important for me:
(setq locale-coding-system 'utf-8)
(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:
Inserts date in ISO 8601 format:
(defun insertdate ()
(interactive)
(insert (format-time-string "%Y-%m-%d")))
(global-set-key [(f5)] 'insertdate)
For C++ programmers, creates a class skeleton (class's name will be the same as the file name without extension):
(defun createclass ()
(interactive)
(setq classname (file-name-sans-extension (file-name-nondirectory buffer-file-name)))
(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)
(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.

Also I recommend these:
(setq visible-bell t) ; no beeping
(setq transient-mark-mode t) ; visually show region
(setq line-number-mode t) ; show line numbers
(setq global-font-lock-mode 1) ; everything should use fonts
(setq font-lock-maximum-decoration t)
Also I get rid of some of the superfluous gui stuff
(if (fboundp 'scroll-bar-mode) (scroll-bar-mode -1))
(if (fboundp 'tool-bar-mode) (tool-bar-mode -1))
(if (fboundp 'menu-bar-mode) (menu-bar-mode -1)))
One line to amend the load path

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.

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

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.
