[][src]Crate newt

newt-rs

Rust bindings for the Newt console UI library.

This crate provides bindings to Red Hat, Inc.'s Newt console UI library. Newt is a small and simple to use UI library providing widgets and basic stacked window management for console applications.

The majority, if not all of Newt's functionality has been implemented. Although some features currently require the nightly build of the Rust compiler.

Example

extern crate newt;
use newt::prelude::*;

pub fn main() {
    newt::init().unwrap();
    newt::cls();
    newt::centered_window(20, 5, Some("Greetings")).unwrap();

    let text = Textbox::new(4, 1, 12, 1, 0);
    let ok = CompactButton::new(7, 3, "Ok");
    text.set_text("Hello World!");

    let mut form = Form::new(None, 0);
    form.add_components(&[&text, &ok]).unwrap();
    let reason = form.run().unwrap();
    newt::finished();

    match reason {
        ExitReason::HotKey(key) => // F12 is the default HotKey
            println!("Execution stopped due to HotKey: {}", key),
        ExitReason::Component(co) =>
            println!("Execution stopped due to Component: {:?}", co),
        _ =>
            println!("Execution stopped due to other reason...")
    }
}

Features

  • asm - Allows building of the Grid module and the windows::win_entries and windows::win_menu functions. These require the inline assembly feature of Rust which is only available in nightly builds. This feature is also only available on x86/x86_64 architectures.

  • static - Builds and links newt-sys statically against its included libraries rather than linking dynamically against available system libraries. This is done automatically if the required system libraries are unavailable.
