comment islands

[moof-src]

using antlr4-4.13.3-SNAPSHOT from a few days ago. I've seen my question answered multiple times, but not in the last 6 years, and not correctly for this version.

I am using a modified grammars-v4r SvLexer where I've added structured comments as new lexer modes, extending the language to have Annotations and Decorators.

I am having trouble finding all of the comments. Since SvParserBaseListener has no methods for anything on the comment channel, I end up missing some comments. I tried using ...Lisenter.enterEveryRule and exitEveryRule and getHiddenTokensTo left and right, but I miss comments, either before the main entry point, or surrounding other channels such as preprocessing, whitespace, or before the EOF.

I've been searching for a couple of days and can't find what I'm looking for, including the ANTLR 4 reference.

How can I find every complete comment in-between other rules in my listener?

Please point me in a good direction.

I just made a loop iterating backwards over the tokens backwards and calling commonTokenStream.get(tokenIndex).getChannel() to find tokens on my comment channel.
