[antlr-interest] Reading all text to end-of-line in a rule

[Martijn Reuvers]

Hello Bill,

As said before most likely your newline is causing problems. I'd
recommend you to get rid of it first (completely including the \r \n
constructs), to the point where your grammar does not give any error
anymore. After that introduce it step by step.

As a side note avoid using text constructs in parser rules (e.g.
'cleanLogs', use real tokens for it). Sooner or later these will cause
trouble, plus that with real tokens you can have better error
reporting.

Regards,
Martijn
