Hi,
I have also run into a related issue caused by the ambiguous lexer
definition - it matched whitespace using dot rule and the
configuration file failed to parse.
I have used the attached patch to resolve it.
Thank you for considering the patch!
Best Regards,
Vladimir.
Description: resolve ambiguity in the configuration grammar
- enable verbose error reporting to be able to see the failing token
- explicitly match '(', ')' and ',' tokens
- require comments to be single line
