Docs Question - Optional Prefix to Regular Expressions

[DavidHVernon]

Thank you for that, but the real issue is that I was reading it in the grocery store checkout line :)

Hey all. Thanks for the help here. Life has gotten in between me and Rust lately, but I've got my head around this now and I suppose we can close the issue.

The example in the repo that uses this is the lrpar/examples/start_states:

https://github.com/softdevteam/grmtools/blob/master/lrpar/examples/start_states/src/comment.l

When the left hand side matches the current state of the lexer (which starts out in the INITIAL state)
it tries to apply the regex, if that then matches the state operation on the right hand side is applied, modifying the current state and a token is produced.

Thank you for the clarification. I'm not quite sure that I follow, but I will give it some more thought before I ask follow-on questions.

I tried to update that hopefully making it a bit clearer.
