Experimenting with programming languages is a whole lot of fun. Unfortunately, it can mean writing a stack of boilerplate before you really get to do anything interesting. By the time you've got Yacc/Bison, Flex and GCC playing nicely together, you might well be wondering why it all has to be this hard. Great news: it doesn't! Racc is Yacc for Ruby: a LALR(1) parser generator that emits Ruby code from a grammar file. The Ruby/Racc combination is the most rapid means I've found for prototyping programming language ideas, and to prove it I intend to build a real, working compiler during this presentation. If you're a newbie to the world of compiler construction, I'll also be giving a brief overview of a generalized compiler architecture along with some basic terminology.
