Hello there,
I have a problem with Grammatica which I can not resolve. I am trying to
parse some LISP like source code by a simple grammar, but it seems that
the constructed parser does not work correctly, it fails to parse
syntactically correct structures. I trying the old versions of
Grammatica and found out it works only with version 1.0. Attached are
the grammar file, the test source file and the output I get when I debug
the parser with the --parse option.
I would appreciate any comments you have.
Regards,
Ivan Vankov
