Hi, just wanted to say you've built something very nice! I just tried it out by re-making a fairly complex diagram and it took me like 10 minutes, including learning the syntax, very nice idea, done well!

I did notice one annoying bug, as I change and break the code sometimes, the editor just stops working and it's hard to tell what's happening (the loading indicator just stays there). Opening the dev tools, it appears you're not catching all errors when your parser (peg.js) fails.
