Open app & game engine on the top of the `bevy` with all the good.

About

polako is the big rethink of the application framework architecture in general and the one plugin for bevy in particular. polako is built on the top of constructivism.

The polako is at the proof-of-concept state. It is possible to define the scene and its behavior with eml! macro (complete example):

fn hello_world(mut commands: Commands) {
    commands.spawn(Camera2dBundle::default());
    commands.add(eml! {
        resource(time, Time);
        bind(time.elapsed_seconds.fmt("{:0.2}") => elapsed.text);
        bind(time.elapsed_seconds * 0.5 - 0.5 => content.bg.r);
        bind(content.bg.hex => color.text);
        Body + Name { .value: "body" } [
            content: Column { .bg: #9d9d9d, .s.padding: [25, 50] }[
                Div { .bg: #dedede, .s.padding: 50 } [
                    "Hello world!"
                ],
                Row [
                    "Elapsed: ", elapsed: Label { .text: "0.00" }
                ],
                Row [
                    "Color: ", color: Label
                ]
            ]
        ]
    })
}

All elements (Div, Label, Row, etc) are implemented in the example. The eml! is designed as tool-friendly-first macro, so a lot of autocomplete, doc strings, goto things are just works. Some of them not (yet).

There is no polako_ui crate yet. Only some parts of the bevy are implemented as Elements, see bridge.rs.

Meaning

Polako is the identity, the lifestyle and the answer to every question of the Serbian people. It also can be translated from one as yet unknown ancient language as 42.
