The specific problem I had was that I created a token in source code with
one token type and text implying another token type. Using ToTreeString
only showed the

For some AST transformations I have to resort to writing code. A recent bug
of mine was due to incorrectly building a AST. Is there any code to
validate the structure of an AST?
Thanks, Eric

Hi Joe,
This feature is not yet implemented in v3. I may be able to get it
implemented for release 3.4, but there are some technical issues that
prevent it from working in a few cases that make it difficult.

There is not enough info in the e-mail for me to determine the exact
problem.
If there is a problem with the grammar ANTLRWorks should catch it when
building. If ANTLRWorks correctly builds the lexer and parser, and then the
error appears when parsing, I would check the input against what the gram

My two cents worth.
I prefer rewrites as I can create virtual tokens.
