indenting and wrapping

indenting and wrapping

[Jeff Hartnell]

Hi,
I have a couple of problems with emacs version 21.3.1 that came with 
SuSE linux 9.2.

1.) C++ mode related

The "basic offset" refered to in FAQ 5.19 is currently set to 4 
white-spaces. I want to set it to 2 white-spaces. I tried
(setq standard-indent 2)
but it has no effect.

Also, another problem, when I write a comment it wont indent on the TAB 
command unless it is at least one white-space away from the margin.

e.g.

if (bla)
  //this will indent on tab
//this one wont until I insert a space in front of it



2.) Latex mode related
I can't change the "M-q" command that wraps all the text to a certain 
width. I tried:

M-x customize-option RET fill-column RET 72

but it doesn't work for latex files (it works fine if I have file.txt say)


I have a feeling that both my problems are related to being in c++ or 
latex mode? Is this right? How do I get round it?

Many thanks,
Jeff.

Use c-basic-offset and set it to 2.

,----[ C-h v fill-column RET ]
| fill-column's value is 70
| Automatically becomes buffer-local when set in any fashion.
`----
Therefore I use Local Variables and it works nicely:
,----
| %% Local Variables:
| %% mode: LaTeX
| %% mode: auto-fill
| %% fill-column: 80
| %% End:
`----

Put the above text (all lines starting at %%) at the end of your
tex-file and see
,----[ (info "(emacs)File Variables") ]
| A file can specify local variable values for use when you edit the file
| with Emacs.  Visiting the file checks for local variable
| specifications; it automatically makes these variables local to the
| buffer, and sets them to the values specified in the file.

Nothing;)

Please keep the discussion on the Emacs mailing list. And no need to
copy me.

Use customize to put it into TeX-mode-hook.
,----[ C-h v TeX-mode-hook RET ]
| TeX-mode-hook's value is nil
| 
| A hook run in TeX mode buffers.
| 
| You can customize this variable.
| 
| Defined in `tex'.
| 
| [back]
`----
Maybe you also want text-mode-hook or similar?
,----[ C-h v text-mode-hook RET ]
| text-mode-hook's value is 
| (turn-on-auto-fill dirvars-hack-local-variables-before text-mode-hook-identify)
| 
| Hook run when entering Text mode.
| 
| You can customize this variable.
| 
| Defined in `textmodes/text-mode'.

maybe this mailing list could be configured
so that
  if you hit reply
  it is sent by default to the list
   , instead of to the sender

thanks

Yes, particularly when so many senders use addresses that don't work ...

Hi Jochen,
Thanks again for your continuing emails. My problems are solved! Your 
talk about "hooks" sent me off in the right direction (I guess hooks are 
a little snippet of code that gets run for particular file types - 
effectively overriding the defaults).

On reading my .emacs I saw that it was loading /etc/skel/.gnu-emacs 
after checking that ~/.gnu-emacs didn't exist. I copied 
/etc/skel/.gnu-emacs to ~/.gnu-emacs and then I edited the lines


;; Fill-column
;; -----------
;;    Fill-column ist hier auf 78 Charakter gesetzt, nach Wunsch "andern!
(setq-default fill-column 78)
(add-hook 'TeX-mode-hook '(lambda () (setq fill-column 78)))


and also


;;
;; Common to all C modes
;; ---------------------
(add-hook 'c-mode-common-hook
    '(lambda () (c-set-style "linux")
	(c-set-offset 'case-label 4)
	(setq c-basic-offset 4)))


to the values of 72 and 2 respectively.

Now, I have the defaults that I want!

Thanks to you and Marek for your help,
Jeff.
