Remember I was going to try writing a language (either #braid, or something Braid-like) that compiles to #go? I decided that I should learn Go a bit more thoroughly before getting stuck into that, and I also wasn’t keen on using yacc for the parsing stage — it’s really old, and has a weird syntax. So why not combine the two and start by porting rply (rpython lex yacc, a modern implementation of those tools) to go? At first I thought this wouldn’t be a huge undertaking, and then of course I realised how little I knew. But tonight I got the lexer finished and working! It didn’t take too long at all. 🎉

I grappled with Go a little bit, but didn’t have huge problems. It’s mostly pointers I have to really think about. I agree with those who say the core language is easy to pick up, although I think people conflate (at least I did) “modern” with “high-level”. It’s really not high-level 😐 but that’s why we’re writing a language on top of it, right?

Maybe tomorrow I’ll start porting the parser.
