Re: Eliminating Left Recursion in Parse::RecDescentby cogent (Monk) |

I'm currently going through the Dragon Book in order to write a parser for JavaScript in pure Perl. Since I'd planned on using Parse::RecDescent, and the grammar (summarized at the end of the standard) is quite large, I'm planning on writing a module to systematically eliminate left recursion. (I also plan to do some other grammar munging, like eliminating epsilon-expressions.)
