If you work with LLM agents, you will immediately be able to tell this issue is written by one. The time cost of this sort is almost certainly not real, as others have pointed out. I’ve had agents find similar “performance bottlenecks” that

I think exposing a C lib would be very nice. Feel free to open a discussion or issue on the Github.

Oh no - where at?

Oh that's cool. `find` is another tool I thought could benefit from io_uring like `ls`. I think it's definitely worth enabling io_uring for single threaded applications for the batching benefit. The kernel will still spin up a thr

You would have to write your IO to have a fallback. The Ghostty project uses `io_uring`, but on kernels where it isn't available it falls back to an `epoll` model. That's all handled at the library level by libxev.

I didn't include `busybox` in my initial table, so it isn't on the blog post but the repo has the data...but I am 99% sure busybox does not have locale support, so I think GNU ls without locale support would probably be closer to

Yeah, I wrote this as a fun little experiment to learn more io_uring usage. The practical savings of using this are tiny, maybe 5 seconds over your entire life. That wasn't the point haha

I've discussed with Mitchell a bit in the past on this, but there are a few ways to opt in to this. First, let's imagine there is some escape sequence that tells the terminal to ignore some set of escape sequences. 1. The shell co

I understand the fear of living near such a heinous crime, but you have to see the difference between the two situations. Random crime is scary, but is random. All signs point to this being an assassination . Brian Thompson wasn't the

It could definitely work for that. You have to think of zig in this context as a build system which can download and compile C/C++ codebases.

Exactly - these should be reported along with any other input event as an escape sequence. There are other comments on this post that link to how this is done.

by rockorager 2y ago
The single downside being you can get signals for SIGWINCH, while the (legacy) xterm escape sequence requires polling. I wrote a proposal[0] to have terminals send these updates in-band, instead of requiring polling a-la xterm. So far, foot

I've been daily driving Ghostty for over a year now, and have been a somewhat regular contributor. As a TUI library author, I've worked with several terminal authors on bug fixes and implementing features - Mitchell is among the n

Ghostty has both mode 2027 and kitty image protocol

by rockorager 2y ago
The state of the art here is to detect mode 2027, and enable it when supported. This lets you know the terminal will handle graphemes properly. I maintain two TUI libraries which use this technique and emoji support has been (nearly) great.

This isn't using any "fancy" terminal features, aside from the synchronized update sequences (which terminals that don't support typically will ignore, though windows has a special case where it must be ignored). That sa

I guess my point is that even for key input, you don't need terminfo. Modern terminals, and I would agree with your definition of that, all use the same keyboard encodings. There is the notable case of backspace/delete you mention

by rockorager 2y ago
> Do you still need terminfo? It depends. If you just want to style some text and maybe do some basic cursor operations: probably not. If you want to use more advanced operations or read key input: probably yes. I disagree. The vast ma

by rockorager 2y ago
Neovim already supports these keys as long as you are using a terminal that supports the Kitty keyboard protocol (Kitty, wezterm, alacritty, foot, ghostty)

Kitty keyboard protocol does indeed support modifier sides.

I don't see why not. 1.0 would mean the API isn't changing. And they can certainly swap out the language and still keep the API the same.

There aren’t any that go direct to maildir. There is mujmap that syncs to notmuch. I wasn’t able to get it to work the way I wanted, and wrote my own that I’d be happy to share. I’ve been using it for around a month with no issues but that’

I'm a chemical engineer myself, and often wondered if there were any others interested in programming as much as I am. I'd be interested to see what sorts of marriages you have made between the two fields. Do you have any links you could

There are very few "sit down and read" type books about chemical engineering. That being said, there are two books that I reference every day: the first physically, the second philosophically. 1) Perry's Handbook for Chemical Engineers (P
