File info in Lexer/Parser

I am working on a plugin that has 5 versions of the language and each language shares the same extension. In order for the plugin to work, I use a check in ParserUtil to see which version has been set in project settings. I would like to have the LexerParser use a language version defined on a per-file basis, not a project basis, as there can be multiple files of different versions in the same project.

I am having a hard time though accessing the virtual file from the ParserUtil class, and I cannot access the PSI file, because it has not been created yet so checking the tree in the builder object throws an error.

My question is, is there a way to read user-data on the virtual file from ParserUtil? Or is there a way to allow per file information access from ParserUtil.

I thought I could alter the lexer to output different tokens based on the desired version by passing in a parameter to the constructor, but again, I cannot see how to access the file's data from the parser definition either.

Is it possible to store file information in a way that is accessible to the Parser and/or Lexer?
