Hi All,
I went through the docs & archives,
But failed to find a good-enough way to preserve comments.
Let me explain what I mean by good-enough:
In the language I parse, comments can appear anywhere.
The grammar I've written for this language is pretty big - around 300 rules.
Whenever a comment is encountered in the input, some specific action must be executed for it.
I understand that I can use a special channel for comments,
But this would require me in each rule I've got, to check that channel for relevant comments.
Moreover, If I want to be precise, I would have to execute the action right after the comment, and not after the rule.
Is there any better way to do this?
Many thanks,
Vitaliy
