What open source (preferably gem-based) parser-generator options do I have in Ruby?

I've used (flex&bison)|(lex&yacc) from C in the past, and I'm comfortable with BNF-style specifications.

I've heard of treetop, but it looks a bit alien and verbose compared to yacc...

Purpose: I want to convert my text markup language to a BNF and generate the parsing code. I think it's a better strategy than my first-order solution: http://github.com/dafydd/semantictext/blob/master/lib/semantictext/rich_text_parser.rb
