Re: Grammars for future languages

In thinking about ''grammars for future languages'' one should not
forget visual languages. Languages like Entity-Relationship diagram,
Petri Nets, Finite State Machines, SDL diagrams all have a clear
semantic and should also have a clear syntax definition. Researchers
in the field of visual languages are working on appropriate syntax
definition formalisms. Such definitions can then be used to specify
syntax directed editors and parsers for these visual languages.


Check the ``Journal for Visual Languages and Computing'' and the
proceedings of the yearly held ``IEEE workshop on Visual Languages''
for more information on these kind of ``future'' grammars for existing
languages.


Kind regards,
