A Compiler Quality Ruby Lexer in Ruby

[Peter Suk]

Folks,

Does anyone know of a program in Ruby that 100% accurately lexes Ruby
1.8? I am prepared to translate a Ruby lexer into Ruby, but I'd rather
have one that's already written.

I think Ripper is the most popular one.

I think Ripper is the most popular one.

I think I cannot use Ripper for my purposes, since its functionality is
not 100% implemented in Ruby. It is partially implemented in C in the
Matz Ruby VM. I need a Ruby lexer & parser implemented 100% in Ruby.
