Hey guys,

I was wondering if there were possiblities to ignore certain errors during parsing. I tried using the error token, but that didn't seem to work. I looked at the following topic http://haskell.1045720.n5.nabble.com/Error-detection-in-GLR-Happy-grammar-td3083740.html 

For my parser I need to be able to parse a certain token at any place, but only in some places it is part of a rule. In other cases this token should be ignored after which the parser just procedes to the next token. Is this possible with Happy? Should I use the monadic parser to achieve this? 

More concretely, I have tokenized some sourcecode which contains comments, these should be ignored except when they are located above a function, in which case I want them to parse.

Any ideas about this issue are greatly appreciated!

Thanks,

Tom
