EMACS newbie

Hey all,
I'm thinking of switcing from VI to Emacs. When I tried to code a C program (hello world

) using emacs, I'm not getting the indentation I get with VI...tabs and stuff. But the parantheses matching is very good. So, any idea how to make `vi-like' indentation work for emacs?

is it in C or Fundamental mode? when you type the first character on a line it should put it in the correct place, or at least it does for me.

When I start it with something like $ emacs test.c, it says "loading CC mode...done" and I understood that it is in C mode...alright. But with VI, when I type enter after main() {, the next line starts after a tab. Not the case with emacs. It's not a big problem, but I'd love to see emacs behave in the way vi did. I'm particular about the vi style of indentation.

The next line does not start with a tab by default. But, as you enter your code in it, and when you enter either a paranthesis, or semicolon, or some similar chars, the line is automatically indended. This provides a more effective indending mechanism, and also helps sort out some typo errors, atleast for me.

As you work more with it, you will understand its value.

Hitting tab or completing a statement performs the indentation, wherever you are on the line, according to your selected indentation style.

Moving the other way, on the rare occaisions I use vi, it is equally frustrating that hitting tab actually inserts a tab character

Below is what I have in my ~/.emacs file. It makes emacs use much different colors possible for syntax highlighting, enables auto-indention, auto-newline and auto-backspace. Put this at the end of your ~/.emacs file and retart emacs to check if it is what you are looking for.

Code:

(setq font-lock-maximum-decoration
  '((c-mode    . 3) 
    (c++-mode  . 3)
    (java-mode . 3)
    (jde-mode  . 3)
    (t         . 3))
)

(global-font-lock-mode t)
(show-paren-mode t)

(defun my-c-mode-common-hook ()
  (c-set-style "k&r")
  (c-toggle-auto-hungry-state t))

(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
