Can syntax depth be supported？

[Yurii-huang]

Sorry, calling lex one-dimensional table seems to have no effect. It seems a bit silly for reference and definition.
But I see checkstyle-8.43-all.jar about syntax parsing. I don't understand the meaning of this git.

Or is there any original intention?
For example, it enables simple syntax diagnosis

I do not quite understand what the issue is, exactly. Could you please rephrase?

This package was intended for obtaining:

1. parse errors from the javac compiler (diagnostics)
2. the one-dimensional token stream from the lexical analysis stage (scanner) of the javac parser

Note that javac does not use two-dimensional information about the source code while parsing -- just when producing error messages. I think it's silly that parsers do not take advantage of the two-dimensional nature of code!
