Robust TUI foundation

Arkham attempts to give a firm foundation for building TUI Apps. It does not provide a set of widgets or components that can be used. Instead, it tries to make the process of building terminal interfaces easy enough that they aren't necessary.

• Keyboard handling

• Terminal modification

• Full screen terminal UIs with alternate screen handling

• Full run loop and rendering engine

• Easy text formatting and styling

• Ergonomic component architecture

• Dependency injection

Components are simple functions

No lifetimes, structs, or traits.

fn my_component(ctx &mut ViewContext) {
    ctx.insert((0,0), "Welcome");
}

Easily handle text styling

Color and style display-able objects with a simple builder pattern.

fn my_component(ctx &mut ViewContext) {
    ctx.insert(
        (0,0), 
        "Welcome"
            .to_runes()
            .bg(Color::Blue)
            .fg(Color::White),
    );
}

Painless dependency injection

Get access to application state, or arbitrary defined resources without having to keep track of and pass them into components.

fn root_component(ctx: &mut ViewContext) {
    ctx.component(Rect::new((0,0), (10,10)), sub_component):
}

fn sub_component(ctx &mut ViewContext, user: Res<MyUser>) {
    ctx.insert(
        (0,0), 
        format!("Hello, {}", user.name),
    );
}

Easy keyboard handling

Straight forward keyboard handling

fn my_component(ctx &mut ViewContext, kb: Res<Keyboard>) {
    if kb.char() == Some('x') {
        ctx.insert(
            (0,0), 
            "X marks the spot"
        );
    }
}
