how to change the indentation style of emacs

how to change the indentation style of emacs

[Anand Dhanakshirur]

Hi,
I am using emacs for c and c++ files.

1. Presently(default), In a C program,
after "for" loop, the next line(the next line starting with
"{" is indented(shifted) by 2 spaces.
I want to change this.
I want the next line is not shifted by 2 spaces when i press TAB key.(for indentation)
basically
Now it is, for (i=0;i<10; i++)
             {
             }

I want this to be changed as 
           for (i=0; i<10;i++)

2 .One more thing want to do.
after opening for loop of if condition,
the next line is getting shiftedby 2 spaces.
I want the next line to be shifted by 4 spaces.

How to do these 2 things?

You can choose indentation styles by using `C-c . <RET> STYLE <RET>'
where style can be tab completed. For more details you can look in the
info manual section 26.3.5 (Programs > Program Indent > Custom C
Indent > Customising C Indentation). If nothing suits you, I think you
can even define your own style.

Hi Anand,

Sorry about that, I should have checked myself. the manual has a typo.
The command is just
`C-c .' This will prompt you for the c indentation style you want to
use. You can see all the built in styles by hitting the TAB key. try
them out, if you feel none of them does what you want, you can
customise and write your own style.

For more detailed information look in these sections of the info manual page:
1. <http://www.gnu.org/software/emacs/manual/html_node/emacs/Custom-C-Indent.html>
(this has the key binding typo, the rest I think is okay)
2. <http://www.gnu.org/software/emacs/manual/html_node/ccmode/Customizing-Indentation.html#Customizing-Indentation>

Good luck.

(define-key global-map (kbd "C-c .") 'c-set-style)

I think you might be looking for:

M-x customize-group <RET> C

Or possibly just

M-x customize-option <RET> c-default-style
