Woah, I'm pretty stoked to see someone link to my ruby implementation (neé Grubby).

It seems like the authors of Golang believe that a lot of problems with languages (refactoring, updating code to work with new libraries / versions, etc) can be solved as parsing problems. Hence, Golang has a lot of good tools for parsing text.

They even ported yacc to Go (via Plan9). http://golang.org/cmd/yacc/

Such as? Do you mean the Go standard libraries for Go code?

Yacc clones exit for almost every language out there, and there are better ways to do parsing than yacc with its stone age error reporting.

I'd be really delighted if you could show me a better tool for writing a parser, given a grammar in Golang than goyacc. You're absolutely right that the error reporting in yacc isn't that modern, but it's very functional, very powerful and (best of all), a lot of people have experience with it.

I certainly couldn't find any better tools in Golang when I started, but I wouldn't be surprised if someone had started one since.
