- The new Amp TUI is 95% written by Amp, with just a few handwritten areas. It's 100% Typescript and can pretty easily run at 60 FPS. The core terminal handling is a basic port of my Vaxis libraries with all the bells and whistles
- Little bit of perf work on @AmpCode today. Got our average frame time down by almost 3x on my machine. Still 100% typescript, still handling unicode. Still D. R. E.
- I spent 11 years in manufacturing automation. Now, I am working on @AmpCode … which you could consider software automation. Lots of lessons learned in producing quality product without human eyes overseeing the entire assembly process. 🤔
- Dear Claude Code, Please stop modifying users' terminal configurations. Sincerely, a TUI dev
- Here's a live one. 319x77 screen (24,563 cells). Full text layout with grapheme segmentation in sub 4ms frame time.

- Dear Claude Code, If you are going to modify user configurations to send something different for Shift + enter, at least be consistent between terminals. Better yet - use the kitty keyboard protocol and stop modifying configurations. Sincerely, a TUI dev
- Everyone: Why would you need good emoji support in a terminal? 2025: You're absolutely right! Build Status: ✅ Build successful! ❌ Build failed! Check logs. ⏳ Compiling... please wait.
- Replying to @mitchellh and @thorstenballEven has support for progress bars in Ghostty ;)
- Replying to @ynorskNone right now. It's entirely contained within the Amp codebase for two reasons: 1. It makes it really easy for Amp to know how to use it 2. It's seeing frequent updates and updating dependencies that often sucks lol
- Replying to @rockoragerSeriously. iTerm2 supports this sw.kovidgoyal.net/kitty/keyboard… there is no need for this hacky workaround
