As announced at RubyKaigi today, I've been working on a new HTML-Aware ERB Parser that I just released today. Introducing Herb — a fast, modern, and HTML-aware ERB parser, designed from the ground up for smarter developer tooling. #rubykaigi #rubykaigi2025

Awesome work Marco! Do you have any plans on making this a replacement for the rendering parser used by rails? I find it really annoying that I can't step into erb files with a debugger and I'm wondering if this approach might helper there.

I was looking into that, but couldn't immediately figure something out. But I'm sure it could improve the error page when you have a syntax error in your view file.

The playground is very cool, always helpful to see how things are working in an easy way. herb-tools.dev/playground.h...
