I played with this last year but couldn’t wrap my head around it. I don’t recall if it was poorly documented at the time or if it couldn’t handle something I was trying to do or if I was just depressed by the generated code quality, but I eventually gave up and tried rolling my own parser by hand. It was the first time I’d done such a thing and I didn’t really understand patterns for writing parsers so I eventually gave up there too. I’m really excited to read Thorsten Ball’s “How to write an Interpreter in Go” book which walks the reader through writing a parser by hand (his blog post about book-writing tools was on the front page here—or maybe it was /r/programming?—yesterday, incidentally).
