What is RCC?

RCC (short for Ruby Compiler Compiler) is a compiler construction system, written in Ruby, which aims to simplify the construction of quality language processors.

With RCC:

Describe your grammar in a flexible, declarative, action-free language.
Generate your lexer, parser, and AST in any modern language.
Easily produce quality error messages during parsing, for a better user experience.
Understand exactly how your grammar processes any source file, with RCC’s debugging tools.

I’m presently in [...]
