The rawkey from sophiajt

rawkey's Introduction

Early release of a project to support raw key input in terminals. Currently, this supports the following raw keys across the major OSes:

LShift - Left Shift (or either Shift on some OSes)
LControl - Left Control
Back - Backspace
Space
Tab
Escape
LeftArrow
UpArrow
RightArrow
DownArrow
PageUp
PageDown
Alt

Rather than using events, rawkey offers a way to scan to see if the key is pressed or not.

use rawkey::{KeyCode, RawKey};

let mut rawkey = RawKey::new();

loop {
    if rawkey.is_pressed(KeyCode::Escape) {
        break;
    }
    if rawkey.is_pressed(KeyCode::UpArrow) {
        print!("Up ");
    }
    if rawkey.is_pressed(KeyCode::DownArrow) {
        print!("Down ");
    }
    if rawkey.is_pressed(KeyCode::LeftArrow) {
        print!("Left ");
    }
    if rawkey.is_pressed(KeyCode::RightArrow) {
        print!("Right ");
    }
    println!("");
}

Can’t build on AArch32 CPU architecture (Raspberry Pi)

Hi there,

I’m trying to get NuShell working on ARM. This package is listed as a dependency and it doesn’t build on my Raspberry Pi 4 which is running Raspbian 32-bit(armv71/AArch32). This is the error I’m getting.

I found a resolution for a similar issue in remacs/remacs#1393. Could we try that fix here and merge it in?
