This code was for ruby 2.4 compatibility, but rdoc dropped support for ruby 2.4 about three years ago, in f480b970c. This code was almost half of the lines of code in rdoc/parser/ripper_state_lex.
Remove unused Ripper constants and const_defined?
This was mostly copied from the diff in @st0012's PR comment. The remaining constants have been updated to get their value directly from Ripper.
Since this is only used from outside RipperStateLex, there's no longer any benefit to using the indirect reference rather than just going straight to Ripper.
