OpenToken 5.0a is released; see
http://stephe-leake.org/ada/opentoken.html.
There are many bugs related to empty productions fixed in this version.
OpenToken can now accept bison-style input syntax, and generate
OpenToken Ada source for declaring the syntax and grammar, or Emacs lisp
source. The Emacs lisp source is used for the Ada and gpr grammars in
Emacs Ada mode 5.0
Happy parsing!

On browsing, I see that the 2012 version of the Ada lexer is missing, which was present 4.0b.
The difference is just the new keyword some. So you could simply replace ada_lexer.ad[s,b] in 5.0a by ada_lexer-2012.ad[s,b] from 4.0b.
Happy lexing!

Hmm.
My monotone CM shows no record of ever adding the keyword "some"; was
that a local addition by you?
I don't have a copy of the 4.0 tar.gz (I guess I should have kept one
somewhere).
In addition, the file makes no claim as to which version of Ada it is
for :).
I'll add it for next time.

Cool!
Are there examples ?
A quick guide ?
A comparison of the workflow between ayacc and opentoken would be nice as well.
Is there a .y/.l to the opentoken grammar format translator (I assume it would be a nice parser example :-) ) ?

Yes, included in the tarball.
It would be good to mention that on the website.

The web page has a small intro. There is a (somewhat dated) user guide,
referenced from the web page.

Yes, but I don't have time for it.

No.
OpenToken was originally designed to be pure Ada code; no separate
grammar language.
I added a Bison style parser, that can generate Ada code, but without
actions. That Bison parser is _not_ implemented in OpenToken; it's quite
trivial.
I think the yacc code would be harder to parse, but probably still not
require OpenToken.
Ada, on the other hand, definitely requires OpenToken :).
