In emacs 28.2 (started as "emacs -Q"), if I have a file

------------------------------------cut here---------------------
#! /bin/sh

while
do
done
------------------------------------cut here---------------------

and I mark the region with the (partial) while loop and then
M-x indent-region
nothing changes.

However, in emacs 30.2, the partial while loop changes to

while
do
done

The same thing happens with "until" loops, but not "for" loops.

Other info: with no condition, in 30.2 with the cursor at the beginning of the "do" line, smie-config-show-indent (C-c ?) says
Rules used: :elem basic -> 4, :after "while" -> nil
whereas in

for
do
done

(i.e., a for loop with no loop variable or list) with the cursor at the beginning of the "do" line, smie-config-show-indent says
Rules used: :before "do" -> 0

For the "while", Emacs 28.2's smie reports this:
Rules used: :before "do" -> 0

Yes, I know I am missing the while condition there, and if I put it in,
emacs 30.2 behaves itself. So I can deal with it.

My question is this: is this an intentional change in smie? I browsed
emacs' NEWS file and didn't see anything about a functional change in smie.

try running M-x normal-mode.
highlight the code and M-x indent-region should work.

I don't think anyone will ever try and modify shell mode. it is some scary software.
you could also try bash-ts-mode, this is new to me.

Not for me, even starting emacs with -q or -Q.

Does it work for you?

New to me, too. In that case the indentation is correct (i.e., "do" is not indented). Since most of my scripts are zsh, that may not be the way to go
for me, but it's good to know about.

Thanks.

I was thinking this newsgroup was completely dead. So your response was a surprise.
