How to parse formal comments?

[Artur Rataj]

Hello!

How would you suggest to parse the code and formal comments in the same parser?

I have formal comments currently defined as special tokens, as in the
demo grammars for Java. Can the contents of the comments be obtained
there just before an instruction after the comment is parsed? Or is it
possible to put formal comments into the parser part and allow them to
occur anywhere, yet still being parsed?

Best regards,
Artur

Ok, I have read the user guide, and there is a variable with contents
of special tokens. So another parser can be run on the contents or
something like that.

Something like that would be easier than altering the grammar to allow
them wherever they could appear.  It's harder still if you are after
any kind of comments as they _can_ appear almost anywhere.

I'm going to guess here that what you're trying to do is related to your original message, and that you're trying to handle both comments and code. And you're attempting to do this in a unique way. Possibly because you don't know the standard way.

If that is the case, I recommend using Lexical States. I had a bit of trouble with them, but it turns out they're not really hard to use, and they're great stuff. Mess around with them a bit (with a different, simpler grammar) and send another message if you're having trouble with them.

If the problem is unrelated,

Either way it sounds like you're doing something interesting, but Lexical states would be an easier of handling comments.
