Oh damn, this is awesome.

I wonder if https://github.com/zed-industries/zed/discussions/18129 is still accurate. Would love to be able to use Ghostty as my Zed terminal.

nice one kyle! you could add https://github.com/wasmerio/webassembly.sh and have a fully featured in browser shell with support for installing packages!

So, could someone now make a Visual Studio Code (and specifically code-server) that has ghostty-web as the Terminal?

Holy shit Kyle. I had no idea you were working on this. This is amazing. Your patch is also very instructive on what you need me to do for you to make this more reasonable.

I'm guessing that performance of this relative to xterm right now isn't... the best, mainly because the way you're grabbing the viewport seems expensive. I'm curious though if you did any benchmarks?

One thing you probably really want to expose is the new RenderState API: https://github.com/ghostty-org/ghostty/blob/main/src/termina... You're doing per row line grabbing currently which is probably pretty slow. The RenderState API is stateful and produces the state necessary to create a high-performance, delta update renderer. It's what our production GPU renderers are now built on (but the API itself is compatible with any kind of renderer). It'd be better for you.

After all that, I'm very curious even at this rudimentary level what the performance on various benchmarks look like compared to xterm.js.

Excellent work!
