Gnu Emacs Ada mode 6.0.0 released

[Stephen Leake]

Gnu Emacs Ada mode 6.0.0 is now available in GNU ELPA. See the
homepage (http://www.nongnu.org/ada-mode/) for news.

This is a major release; an error correcting parser written in Ada is
provided, and the grammar actions have been rewritten to implement
indentation more efficiently. The Ada parser is useable on very large
files. The elisp parser is still available, but does not provide error
correction.

Nice!
Thank you for your work on Ada mode.

Is this a brand new (written from scratch) parser of the Ada2012 language?  Or is it derived from GNAT?

It is not derived from GNAT.

There has been an LALR parser in GNU ELPA ada-mode for 5 years now, and this parser is derived from that one. The major new feature is the error recovery.

Thanks. This fixes the only annoyance that I had with 5.0.0, that a
'procedure' would be indented too far if it followed a function
with a parenthesized body (that wasn't on the same line as its
'function').

It requires me to update my hack to ada-mode though, previously to the
ada-adjust-case-interactive function. I changed that function so that
I could type

  words-like-this with-dashes as-the-alternative-is-actually-painful

and get

  Words_Like_This With_Dashes -- etc.

My hack wasn't very robust. It just inserted _ instead of - if the
previous char in the buffer was some kind of [[:alpha:]]

That update wasn't too hard. The function's now ada-case-adjust-interactive ,
and I just added an additional test before the T case

     ((and (eq lastk ?-)
           (save-excursion (ignore-errors (re-search-backward "[[:alpha:]]" (- (point) 1)))))
      (when ada-auto-case
        (ada-case-adjust lastk))
      (insert "_"))

I'd have gone for [[:alnum:]] but then I'd never write 1-2 if I meant an
arithmetic expression! (since -gnaty would complain)
