`indent-tab-mode' has nothing to do with how the indention of certain
programming language constructs looks like. If it's non-nil, indentation
uses tabs, if it's nil it uses spaces.

,----[ C-h v indent-tabs-mode RET ]
| indent-tabs-mode is a variable defined in `C source code'.
|
| [...]
| 
| Documentation:
| *Indentation can insert tabs if this is non-nil.
| Setting this variable automatically makes it local to the current buffer.
`----

I think it's quite common not to indent `then':

,----
| if [...]
| then
|     do-this
|     do-that
| done
`----

Another common style is:

,----
| if [...]; then
|     do-this
|     do-that
| done
`----

Bye,

then how can I indent-while-typing this code
#!/bin/sh
#
# if not vehicle name is given
# i.e. -z $1 is defined and it is NULL
#
# if no command line arg

if [ -z $1 ]
then
rental="*** Unknown vehicle ***"
elif [ -n $1 ]
then
# otherwise make first arg as rental
rental=$1
fi

case $rental in
"car") echo "For $rental Rs.20 per k/m";;
"van") echo "For $rental Rs.10 per k/m";;
"jeep") ehco "For $rental Rs.5 per k/m";;
"bicycle") echo "For $rental 20 paisa per k/m";;
*) echo "Sorry, I can not get a $rental for you";;
esac

C-q TAB

Or: some spaces as indentation and in the next line(s) a TAB.

the expected results:




#!/bin/sh
#
# if not vehicle name is given
# i.e. -z $1 is defined and it is NULL
#
# if no command line arg

if [ -z $1 ]			# first arg not given?
    then
    rental="*** Unknown vehicle ***"
elif [ -n $1 ]			# first arg given
    then
# otherwise make first arg as rental
    rental=$1
fi

case $rental in
"car") echo "For $rental Rs.20 per k/m";;
"van") echo "For $rental Rs.10 per k/m";;
"jeep") echo "For $rental Rs.5 per k/m";;
"bicycle") echo "For $rental 20 paisa per k/m";;
    *) echo "Sorry, I can not get a $rental for you";;
esac

Use C-j to carriage return or put the following in your .emacs:

(global-set-key "\C-m" 'newline-and-indent)
(global-set-key "\C-j" 'newline)
