Please for the love of god how can I make Emacs stop auto-filling? I use visual-line-mode, I do not want auto fill. I can turn it off with M-x auto-fill-mode RET but in Noweb mode it gets turned back on when I move into a code chunk and back out again. Please, I just want to globally turn of auto fill mode, it's driving me crazy.
I've tried
(auto-fill-mode 0)
and a bunch of crazy things like
(add-hook 'Rnw-mode-hook '(lambda () (auto-fill-mode 0)))
(add-hook 'latex-mode-hook '(lambda () (auto-fill-mode 0)))
But nothing seems to work. Please help me.
Instead of adding further hooks to your system, you should check if you could remove some to disable auto-fill.
If you see noweb-mode's source code, around line 211 you find this chunk:
(add-hook 'noweb-select-doc-mode-hook 'noweb-auto-fill-doc-mode)
(add-hook 'noweb-select-code-mode-hook 'noweb-auto-fill-code-mode)
To disable auto filling, put the following one or two lines in your dotemacs (depending on whether you want to disable auto-fill in both code and documentation).
(remove-hook 'noweb-select-doc-mode-hook 'noweb-auto-fill-doc-mode)
(remove-hook 'noweb-select-code-mode-hook 'noweb-auto-fill-code-mode)
OK, I worked out a hack that does the trick:
(setq auto-fill-mode -1)
(setq-default fill-column 99999)
(setq fill-column 99999)
If I can't turn off auto-fill mode, at least I can make it harmless by setting it to fill only in column 99999. I'll be annoyed if I type a paragraph with more than 99999 characters, but if that happens I'll have bigger things to worry about...
If you look at simple.el, at the very top text-mode-hook is defined, which is ultimately responsible for turning on this abomination (or at least, it was for me).
To get to simple.el and look for yourself: (C-h f, auto-fill-mode, click / follow simple.el link)
To disable, M-x customize-variable text-mode-hook
Screen shot
Uncheck turn-on-auto-fill. Be sure to click "Save for future sessions" at the top.

I set up emacs to turn flyspell on by default for text mode using
(add-hook 'flyspell-mode-hook 'flyspell-buffer)
(add-hook 'text-mode-hook 'flyspell-mode)
I would like to disable it automatically in org mode files, and I did manage to disable it using a lambda function in the org mode hook:
(add-hook 'org-mode-hook (lambda () (flyspell-mode -1)))
This works, but the syntax highlight changes that flyspell did still remain, and interfere with org mode's syntax highlight. I also see in the minibuffer that flyspell does run when I visit that file, so apparently it is turned off only afterwards. How do I turn it off in such a way that would leave no trace of it in the org mode file, or better yet not run at all?
You can selectively enable flyspell in text-mode hook by checking the major-mode. The following will enable flyspell in text-mode and its derived modes except org-mode
(add-hook 'flyspell-mode-hook 'flyspell-buffer)
(add-hook 'text-mode-hook (lambda ()
(when (not (equal major-mode 'org-mode))
(flyspell-mode t))))
Regarding the first question (remove the highlightings), the following call should do it:
(flyspell-delete-all-overlays)
However, are you really, really, really sure you want to disable flyspell in Org mode??? Is there a really, really, really good reason for that?
If yes, shouldn't you solve that one, instead of trying the above?

Now I'm editing c sources with emacs under c-mode. How ever auto-fill-mode doesn't seem to work at all. Here how I enabled and tried to use it.
M-x auto-fill-mode (enable auto-fill-mode)
Typed in a line longer than auto-fill size(which 80 characters for now) --> didn't break the line
Tried to auto-filled by issuing M-q
However above attempt didn't work out at all.
Could anybody point out that what have I done wrong?
Thanks for your help in advance.
When you use auto-fill-mode in c-mode, the default behavior is to wrap text only when writing text, as in a comment. You can override this by customizing the value of c-ignore-auto-fill. Note that emacs will wrap and indent your code as text, which is probably not what you want.
A better solution is probably to bind space to a function like this:
(defun insert-space-or-newline-and-indent ()
(interactive)
(if (>= (current-column) fill-column)
(newline-and-indent)
(insert-char ? )))
Today I got my new PC (Windows 7, 32 bit) and installed Vincelt Goulets Emacs. The only other thing I did was updating Org-mode.
Now, I am stuck with auto-fill-mode on every time I start Emacs new, which I hate. I would like to turn auto-fill-mode off, for now and forever. I even deleted my .emacs file, but auto-fill-mode was still turned on.
The only solution that worked was (a) a nasty workaround or (b) always typing M-x auto-fill-mode every time I start Emacs anew.
Is there a solution?
To be clear, the only thing the current .emacs file contains is: '(inhibit-startup-screen t)
Add to your .emacs,
(auto-fill-mode -1)
If there are hooks for specific modes, you will need to zap those as well. My suspicion is that you do not actually have auto-fill-mode on by default in all modes, but with the information you have supplied, at least this should be a starting point.
A reasonable safeguard would be to also disable auto-fill mode from `text-mode-hook':
(remove-hook 'text-mode-hook #'turn-on-auto-fill)
You may need something similar for other modes as well.
Assuming that he has not made fundamental changes, you have several paths:
You can just turn off the mode globally in your .emacs file:
(turn-off-auto-fill)
;; ...or (auto-fill-mode -1)
Since Emacs of that vintage also turns on auto-fill for text-mode, add:
(remove-hook 'text-mode-hook 'turn-on-auto-fill)
That should account for all the default places, but check the major mode hooks if you have other modes enabling this automatically.
If you'd like to keep it turned-on in most text-mode while disable auto-fill in specific modes, e.g. org-mode in my case, you could use the following:
;; turn on auto-fill for text-mode
(add-hook 'text-mode-hook 'turn-on-auto-fill)
;; turn off auto-fill for org-mode
(add-hook 'org-mode-hook 'turn-off-auto-fill)
I'm an Emacs user with no skills with regards to configuring the editor. After I upgraded from haskell-mode 2.4 to 2.7, I've noticed two changes:
Indentation is different somehow, in a way I don't quite like. I can't quite put my finger on what it is.
More importantly: If I have cua-mode enabled and highlight a block of text, backspace/delete does not delete the entire block, just the previous/next character from my marker.
I see that haskell-mode 2.7 uses the minor mode haskell-indentation-mode by default, while 2.4's behaviour has been preserved in the form of haskell-indent-mode. If I first turn off the former, and then on the latter, the behaviour I want is restored (i.e. indentation feels like before, and backspace/delete deletes highlighted blocks).
I can't, however, get this to happen automatically whenever I open a file with a .hs suffix. I've tried various things resembling
(remove-hook 'haskell-mode-hook 'turn-on-haskell-indentation-mode)
(add-hook 'haskell-mode-hook 'turn-on-haskell-indent-mode)
and the likes of it, but I either end up with the standard mode or with plain haskell-mode without indent and doc.
Any ideas?
Solution (thanks to nominolo):
(remove-hook 'haskell-mode-hook 'turn-on-haskell-indent)
(remove-hook 'haskell-mode-hook 'turn-on-haskell-indentation)
(add-hook 'haskell-mode-hook 'my-haskell-mode-hook)
(defun my-haskell-mode-hook ()
(haskell-indentation-mode -1) ;; turn off, just to be sure
(haskell-indent-mode 1) ;; turn on indent-mode
)
The best way to configure such things is by writing a custom hook:
(add-hook 'haskell-mode-hook 'my-haskell-mode-hook)
(defun my-haskell-mode-hook ()
(haskell-indentation-mode -1) ;; turn off, just to be sure
(haskell-indent-mode 1) ;; turn on indent-mode
;; further customisations go here. For example:
(setq locale-coding-system 'utf-8 )
(flyspell-prog-mode) ;; spell-checking in comments and strings
;; etc.
)
You could also stick an anonymous function in there, but having a named function is easier if you want to experiment with some settings. Just redefining the function (and re-opening a Haskell file) will give you the new behaviour.
I'm kind of a newb when it comes to emacs. I know about the .emacs file but have very little idea as to do anything more advanced than elementary stuff.
Whenever I enter latex-mode, I'd also like to automatically turn on flyspell-mode, reftex-mode, auto-fill-mode, and also set fill-column to 120. How do I edit my .emacs file to do this?
Thanks!
(add-hook 'latex-mode-hook
(function (lambda ()
(flymake-mode)
(reftex-mode)
(auto-fill-mode)
(setq fill-column 120))))
for example should work.
You can set a so-called hook to a major mode. Have a look at this page of the manual for some examples.
