Look into Stephen Leake's work on the Wisi parser
which relies on OpenToken. It is distributed as part
of the new Ada mode for Emacs; file "ada-grammar.wy" is
a grammar for Ada 2012, made flexible in order to handle
incomplete text while editing.

(My own little recursive descent parser for Ada was made
for pretty printing Ada to HTML, TeX, Wiki markup, etc., but
is not Ada 2012. It looks at comments, too, to some extent.
Updates needed, theoretically.
