Creator of Ghostty here. Always a fan of new terminals. I noticed your benchmarks are against Ghostty 1.3.1, which is fair, since its the latest released, but our IO throughputs in particularly the areas you tested have improved by more tha

Case-in-point, the example in my own post doesn't auto-vectorize with LLVM or GCC at highest optimization levels. Basically, compilers will never auto-vectorize loops with an early loop break afaik.

I'm the creator of Ghostty. This isn't right. It should idle at 0 to 1%, as supported by sibling comments. If you can collect more details about your system please open a discussion on the main Ghostty repo. Same with memory. In t

As with all things, the horror stories just get the most attention. People love to rage. There are plenty of boring (good, even!) VCs out there. They just work more quietly, professionally. I'll share a story, but its about a close fri

Correct. I use AI a ton and I'm having more fun every day than I ever did before thanks to it (on average, highs are higher, lows are lower). Your characterization is all very accurate. Thank you. Here's some other topics I'v

Yep! To be more specific, Open Source only promises the four fundamental freedoms ( https://en.wikipedia.org/wiki/The_Free_Software_Definition ). It promises literally NOTHING else, including zero cost. Free and open sou

I know this is ridiculously dramatic, but its the truth: I actually cried writing this blog post (tears hit my keyboard, I'm embarrassed to say). Nobody should cry over a SaaS, of all things. But GitHub has meant so much more to me tha

Well, I originally used C23's #embed directive ( https://en.cppreference.com/w/c/preprocessor/embed ) but GCC in Nixpkgs doesn't support C23 (or I'm holding it wrong) so I dropped back to this. T

Just noting that Ghostty shows a preview in the bottom corners just like a browser.

Im touched that “Ghostty but for X” is a marketing point but what does it mean in this case? I thought this might be based on the architecture I did for Ghostty. But it’s not. Or it might be full native UI, but it’s not (it’s GPUI). Not try

I'm not concerned with it. The real goal isn't for Alacrity or Kitty or WezTerm or any other terminal to use libghostty. I think over the long term, terminal emulator user bases dwindle down to niche (but important) use cases. The

Probably not. I don't know. Who cares.

Not at all. Give it tools and skills and it figures it out very quickly. Must be an agent. Don't use chat.

by mitchellh 7mo ago
Yes, LLMs with Zig are absolutely useless without agentic behaviors. Throw an agent in the mix and it's totally fine. Bonus points if you pair it with some basic agent skills so it knows how to look up language references, stdlib files

It's been extremely good. I should really blog about it in more detail because I do get asked this question regularly. It's been very good. The large language changes are a burden, but it's something I knew going into it. And

Overall I would describe it as "amusing." If you told me 3 years ago that terminal usage would _increase_ I would've laughed. Beyond that, I'm now having regular conversations with the frontier agentic coding companies (

Note in Ghostty 1.3 we disable discretionary ligatures (I think dlig/calt) by default as recommended by font standards. We still enable liga though that usually contains far less controversial ligatures.

I'm the original creator of Ghostty. It's been a few years now! I don't know why this is on the front page of HN again but let me give some meaningful updates across the board. First, libghostty is _way more exciting_ nowaday
