[antlr-interest] Stripping actions and tree commands out of a grammar

[Nikolay Ognyanov]

Can somebody please advise whether there is a way/tool to automatically
strip out of an ANTLR grammar all actions and tree comands? A pure
grammar with these parts stripped is useful for documentation and
presentation purposes. It is my feeling too that it would be useful to
have a clear view of the uncluttered grammar during the process of
development of a new language.

Thank you
Nikolay
