Crate ravenrs_app_a11y 

The accessibility of a RavenRS business application, so that every application made with ravenrs-app reaches screen readers and the keyboard with nothing written for them.

• AccessibleText says what a field or an action is called and what is said after it, from the model: the caption, unless the declaration or the model says otherwise.
• Announcer says what changed, such as a record kept or deleted, through a LiveRegion.
• AccessWords are the words of those announcements, by key, in each language.
• Audit walks an application with no window and says what keeps someone out: a control with no name, focus that is held, contrast too low on its themes, two commands on the same keys. A test of any example calls it.

use ravenrs_app_a11y::{AccessibleText, Audit};
use ravenrs_app::{FieldInfo, FieldKind};

let until = FieldInfo::new("until", FieldKind::Date).caption("Até").accessible_name("Fim do período");
assert_eq!(AccessibleText::of_field(&until, None, "Até").name, "Fim do período");

let mut ui = ravenrs_widgets::Ui::new(ravenrs_widgets::Button::new("Salvar"), ravenrs_style::Theme::raven_light());
Audit::new().screen(&mut ui, "início").assert_clean();
