Need help w/ ada-mode.el under Emacs 21.

[Bobby D. Bryant]

After a general system upgrade my Ada-mode for Emacs is behaving
differently, and I'm having trouble restoring the earlier behavior.

The behavior that I want to suppress is that whenever you press return on
an empty line to create more whitespace I get an indentation on the new
line, and I want the cursor to stay at the left margin unless I press the
tab key.  Previously it would guess an indentation if I were in the middle
of a declaration or a statement, but not otherwise, and that is the
behavior that I would like to restore.

I see that I can suppress re-indentation of the *current* line by adding
(setq ada-indent-after-return nil) to my ~/.emacs, but that's not what I
want to change -- I want to change indentation of the line where the
cursor ends up after pressing return.  Nor do I want to disable
indentation altogether; I just want to disable contextless indentation. 
(While working on complicated problems I like to put "lose end" comments at
the left margin so I can find them more easily by skimming, and it's
really annoying to have to move every line back to the margin by hand.)

Any help would be appreciated.

Are you now using a different version of ada-mode than before?

Has there been any change to your .emacs?

Presumably so, since the upgrade provided a newer version of Emacs.  I
tried to look at ada-mode on my system that hasn't been upgraded, but for
some reason it only had the compiled version of the ada-mode.el, so I had
trouble comparing them for changes.

No, not before I started trying to fix it.

The reason I asked about the version is that the version that comes
with Emacs is different to the ACT version. You may want to try to
install the ACT version from
http://libre.act-europe.fr/adamode/main.html and make sure it is
loaded before the default version to see if that helps.

Hmmm....

As far as I know, the real last version of ada-*.el is at
http://savannah.gnu.org/cgi-bin/viewcvs/emacs/emacs/lisp/progmodes/

For example, ada-mode 3.6 from http://libre.act-europe.fr/adamode/main.html
does not seem to support (perfectly) the new .ali format appeared in gnat
3.15.
If I remember correctly ...

Thanks for that.

I think you're right. It would be nice if the ACT free download and
GNU versions at least appeared to be consistent :-)

I suspect you are going to have to write a custom indentation
function. 

It's easy to disable all indentation on return; just rebind the return
key.

But what you are asking for is more complicated. I suspect the
ada-mode with emacs 21 got "smarter", and therefore now does more than
you want.

You can retrieve the ada-mode source from an old distribution of
Emacs, but it's pretty dense (I've tried to fix indentation issues
myself), so that probably won't help much.

Post a few actual examples of "before", "after" and "desired"; maybe
I'll have an idea.
