AdaGIDE 7.42 and tabs

[Dmitry A. Kazakov]

Does anybody know how to force AdaGIDE to use HT properly (tab stop = 8)?

Tools => Global settings => [Editor tab] => Indent Spaces/block => 8

No chance to separate indentation from source HTs?

Not that I'm aware of. Do you have sources with tabs for other than 
indentation?

Sure, all of them in fact. Indentation = 3, HT = 8.

It worked satisfactory in earlier versions of AdaGIDE. Or, maybe, I just
haven't noticed anything wrong. But now indentation seems to be expanded as
1 HT, when set to 3 spaces. Clearly 1*8 /= 3! So when the file gets opened
in another editor, the result is a total mess.

Not sure about changes about h-tabs; at some point of time around 7.0
version, there was a change from RichEdit 1.0 to RichEdit 2.0.
Anyway, my trick is just to avoid that character, because you always
get problems (50% of editors, formatters etc. think that HT must be 4
characters, the other 50% that it must be 8).
Then, use spaces, don't worry and be happy!

I don't believe there is any sort of actual _standard_ that says HT =
column mod 8. 

On some old mechanical typewriters, you could set mechanical tab stops
where ever you wanted, to make typing tables etc easiser. Early
printers also had configurable tab stops (not mechanical).

Good editors also have configurable tab stops. 

But the only portable way to use tab stops is to insert spaces, not HT.

This is my impression too. However it is a de-facto standard.

Which is the root of the evil! A tool that requires configuration is a bad
tool. I am almost serious here... (:-))

That would be fine to me, unfortunately indent-block inserts HTs.

In this ada-mode, there's a write-file-hook that removes trailing
spaces & untabifies the buffer.

(defun ada-set-write-file-hook ()
  "Reset the `local-write-file-hooks' for support of ada-mode.
As a result, the buffer is cleaned up upon saving, according
to the rules described for `ada-clean-buffer-before-saving'."
  (if (and ada-clean-buffer-before-saving
           (null local-write-file-hooks))
      (progn
        ;; remove all spaces at the end of lines in the whole buffer.
        (add-hook 'local-write-file-hooks
                  'delete-trailing-whitespace)
        ;; convert all tabs to the correct number of spaces.
        (add-hook 'local-write-file-hooks
                  (lambda () (untabify (point-min) (point-max))))
        )))

I don't think AdaGIDE can interpret Emacs lisp. It would be
interesting if it could !

I suppose it would be called Emacs then. (I did suspect I might have
got the wrong end of the stick there)

I'm not seeing this. All indentation is done using spaces.

Yes, you are right. The effect appears only when the file already contains 
HTs. Indent leaves HTs. Further AdaGIDE expands them wrong. I set indent = 
8 and created the following file

<HT>1
<HT><HT>2
12345678901234567890

In AdaGIDE it is displayed as

______1
____________2
12345678901234567890

And also unindent does not consider HTs as blanks! I can't unindent past a 
HT. It is strange.

If there is no configuration setting to tell AdaGIDE to not do that,
AdaGIDE needs to be fixed.

Right, but the tab key did not insert 'tab' characters (no such thing)!  ;-)

Exactly.
