You're not the first to have thought of that. I'm failing to locate
any relevant threads in our archives, but I distinctly recall having
heard of somebody who'd made a standalone version of our lexer+grammar.
You might try searching on github.
(I make no warranties about how up-to-date any such project may be.)
