harzu / iced_term Goto Github PK

Hey, been trying to set the term view up but have been getting the error in the title. Coredump isn't helpful unfortunately, core rendering stuff and stacktrace im too dumb to decipher (pointers to memory in the binary im assuming, but idk how that would help in current situation), and RUST_BACKTRACE=full doesnt show anything either. I'm pretty much following the examples, i create and store Term in App in new() and pass reference to it from &self to term_view() in view(), check for events in update(), closing window on Shutdown request, and doing the subscription thing as well.

My theory is that the Fd gets dropped unexpectedly at some point but I can't figure out why since judging by the code (at first glance at least) and types used to store the Fd, it shouldn't happen? Mb I'm blind and missing some crucial step required to keep the descriptor alive, but as i said before, semantically my logic for handling Term is identical to the examples.

I will say that I don't store settings in App, but just generate them in separate function to immediately pass them to Term constructor (I'm planning to make some customizable behavior for opening new terminals, so i wanna generalize it under one function), which will get returned from said external function upon initialization. But I don't think this would cause the issue right?

Does Rust stable/nightly matter? (I'm on nightly 2024-05-01). Also, in case it's useful, I'n on NixOS, using nix-cargo-integration flake template, with dependencies to run the application set up (checked before termview was added).

I thought that maybe it could've been alacritty crate that's at fault but I didn't find any issues regarding this error in their repo.

Thanks in advance!

Problem description

winit and iced handle scrolling of macbook's trackpad by pixels instead of lines.
winit and iced have 2 different types of mouse wheel event

iced::mouse::Event::WheelScrolled { delta } => match delta {
    ScrollDelta::Lines { x: _, y } => Event::Scrolled(self.id, y),
    ScrollDelta::Pixels { x: _, y } => Event::Scrolled(self.id, y),
}

but widget handles ScrollDelta::Lines and ScrollDelta::Pixels the same, so scrolling will be faster than need on some devices like macbook's trackpad

Showcase

Expected behaviour

Scrolling works based on lines delta on any devices

Possible solving

convert pixel count to lines count and provide it to backend as the same way as it is implemented in ScrollDelta::Lines handler

Problem description

Widget does not render all colors that backend is provided to it.
Alacritty backend has 3 types of colors.

1. NamedColor
2. Spec(r, g, b)
3. Indexed(u8)

Widget does not render any Indexed color.
