vim newbie question about formatting code

I just started learning vim and am wondering how I can get it to auto format some code.  For example:

check() {
for i in $nodes; do
ping -c 1 $i > /dev/null
if [ $? -eq 0 ]; then
echo "Looks like $i is up so initializing the cluster on it."
ssh $i "\$HOME/bin/cluster-setup.sh"
fi
done
}

I have tabstop=3 in my ~/.vimrc and I'd just like to apply formatting to that code block so it looks like:

check() {
for i in $nodes; do
   ping -c 1 $i > /dev/null
      if [ $? -eq 0 ]; then
         echo "Looks like $i is up so initializing the cluster on it."
         ssh $i "\$HOME/bin/cluster-setup.sh"
      fi
done
}

I read about =i{ but it has no effect for me.

Thanks!

You need to put in your .vimrc

set autoindent
filetype indent on

Also, be sure to read the help topics 'cinoptions', cinoptions-values and
C-indenting. If you should run into any problems, the guys over at freenode's
#vim channel are very helpful and eager to help out

Edit:

Oops, just realized this is shell script code we're talking about... My bad.

Re: vim newbie question about formatting code

graysky,

If you want vim to autoindent while typing, customize your ~/.vimrc file. I posted mine here: http://linuxandsuch.wordpress.com/2011/06/19/my-vimrc/ a few days back. I recommend all the options.

However, if you want to indent an already existing file use the indent program. Install with

sudo pacman -S indent

And then, to indent your file, run:

indent myfile.c

I'd recommend reading the manpage for indent to learn to tweak it to your coding style though .
