let w = fn_widget! {
  @Text {
    on_tap: |e| {
      // Query the `Palette` of the application theme.
      let mut p = Palette::write_of(e);
      if p.brightness == Brightness::Light {
        p.brightness = Brightness::Dark;
      } else {
        p.brightness = Brightness::Light;
      }
    },
    text : "Click me!"
  }
};

App::run(w);

core: Added Provider widget to share data between sub-tree. (#618 @M-Adoo)

Provider::new(Box::new(State::value(0i32))).with_child(fn_widget! {
  @SizedBox {
    size: Size::new(1.,1.),
    on_tap: |e| {
      // Access the provider in a callback.
      let mut v = Provider::write_of::<i32>(e).unwrap();
      *v += 1;
    },
    @Text {
      text: {
        // Access the provider in any descendants
        let v = Provider::of::<Stateful<i32>>(ctx!());
        let v = v.unwrap().clone_writer();
        pipe!($v.to_string())
      }
    }
  }
});

core: Added Overlay::of to allow querying the overlay in event callbacks. (#618 @M-Adoo)

core: GenWidget::gen_widget no longer requires a &mut BuildCtx parameter. (#616 @M-Adoo)
core: Removed FullTheme and InheritTheme, now only using Theme. Any part of the theme, such as Palette, can be directly used to overwrite its corresponding theme component. (#618 @M-Adoo)

0.4.0-alpha.5 - 2024-08-14

Features

core: PartData<T> now supports T: ?Sized, allowing us to separate trait objects from State.(#614 @M-Adoo)

0.4.0-alpha.4 - 2024-08-07

Features

core: Introduced IntoWidget and IntoChild. (@M-Adoo #612)

The IntoWidget trait allows for the conversion of any widget to the type Widget. The IntoChild trait provides a way to convert a more general type into a child of ComposeChild.

Fixed

core: The generation of a pipe widget from another pipe widget may potentially result in a crash. (#612, @M-Adoo)

Changed

core: Lazy build the widget tree. (#612, @M-Adoo)

Features

core: Added support to query a WriteRef from a state, enabling users to modify the state after attaching it to a widget. (#601 @M-Adoo)
core: Introduced the DeclareInto trait for any type that implements DeclareFrom. (#604 @M-Adoo)

macros: Improved widget declaration to allow specifying widget types via path. (#606 @M-Adoo)

  // Previously, a widget type could only be specified using an identifier, requiring prior import of `Row`.
  use ribir::prelude::*;
  fn_widget! {
    @Row {
      ...
    }
  }

  // Now, the widget type can be specified using a path, removing the need for a prior import.
  fn_widget! {
    @ribir::prelude::Row {
      ...
    }
  }

Changed

core: Render widgets no longer need to implement the Query trait. Data can only be queried if it's a state or wrapped with Queryable. (#601 @M-Adoo)

core: Removed the infrequently used StateFrom trait, as there's a more efficient alternative. (#604 @M-Adoo)

0.4.0-alpha.1 - 2024-06-12

Changed

core: Removed the unused stamp checker for the split state. (#599 @M-Adoo)

0.3.0-beta.2 - 2024-06-05

We're thrilled to announce that Ribir now supports the Web platform! 🎉🎉🎉

Experience the power of compiling Rust code to wasm and rendering it with WebGPU or WebGL.

Check out our Wordle game demo, now running smoothly in your browser!

Features

ribir: support stable Rust 1.77.0 (#552 @M-Adoo)
macros: Added a include_crate_svg! macro to include the svg relative to current crate. (#552, @M-Adoo)
ribir: Added a nightly feature to enable functionalities that require nightly Rust. (#552, @M-Adoo)
- The include_crates_svg! macro can operate without the nightly feature.
- The include_svg! macro requires the nightly feature to be enabled.
ribir: Introduced AppRunGuard to allow app and window configuration prior to app startup. (#565, @M-Adoo) Previously, to configure the app and window before startup, App::run couldn't be used:
```
unsafe {
  AppCtx::set_app_theme(material::purple::light());
}

App::new_window(root, None).set_title("Counter");
App::exec();
```
Now, with AppRunGuard, you can use App::run and chain the configuration methods:
```
App::run(root)
  .with_app_theme(material::purple::light())
  .with_title("Counter");
```
core: The split functions in StateReader::map_reader, StateWriter::map_writer, and StateWriter::split_writer no longer need to return a reference. (#568 @M-Adoo)
core: Introduced StateWatcher for watching state modifies, which was previously the responsibility of StateReader. This results in a cleaner and more compact StateReader implementation. (#556, @M-Adoo)
gpu: Introduced GPUBackendImpl::max_textures_per_draw to set a limit on textures per draw phase (#562 @M-Adoo)
gpu: Updated the wgpu implementation of the GPU backend to support WebGL. (#578, @M-Adoo)
ci: add wasm test (#583 @wjian23)
ci: wasm server watch file change (#586 @wjian23)
painter: Introduced support for Resource<Path> for drawing. This indicates that the Path may be shared with others, allowing the backend to cache it. (#589 @M-Adoo)
painter: Introduced support for bundled commands, enabling the backend to process these commands as a single entity and cache the resulting output. (#589 @M-Adoo)

Fixed

examples: fix crash issue in Storybook (#559 @M-Adoo)
ribir: Resolved the issue causing a black screen on the first frame. (#566, @M-Adoo)
gpu: Retrieve the texture limit size from the GPU instead of using a hardcoded value. (#578, @M-Adoo)
ribir: fixed the crash issue when the shell window is zero-sized at startup. (#582, @M-Adoo)

Changed

core: Enhanced panic location tracking during widget build (#559 @M-Adoo)
core: rename builtin field of delay_drop_until to keep_alive (#561 @wjian23)
macros: polish the compile error message of invalid filed in @$var {} (#556 @M-Adoo)
gpu: Removed dependency on the texture array feature of wgpu. (#562, @M-Adoo)
algo: removed Resource and rename ShareResource to Resource. (#564, @M-Adoo)
dev-helper: Support specific the comparison of image tests. (#573 @M-Adoo)
dev-helper: If test images differ, both actual and difference images are saved with the expected image. (#573 @M-Adoo)
painter: Removed the AntiAliasing feature from the painter package, This responsibility now lies with the painter backend. (#584 @M-Adoo)
gpu: The GPU backend no longer relies on MSAA, which is dependent on the graphics API. Instead, it uses the alpha atlas to provide a solution similar to SSAA.(#584, @M-Adoo)
example: run example in web wasm (#571 @wjian23)
gpu: The GPU backend now only caches the path command if it is a Resource. This change reduces GPU memory usage and accelerates cache detection. (#589 @M-Adoo)
text: Implemented caching of the glyph path as a Resource to improve performance. (#589 @M-Adoo)

Documented

core: Explained when to use unsubscribe with watch!. (#556, @M-Adoo)

Breaking

ribir: compile wasm (#543 @wjian23)
ribir: Updated App::new_window to accept WindowAttributes instead of size as the second parameter. (#565, #566, @M-Adoo)
ribir: The window creation APIs have been updated to use asynchronous methods, improving compatibility with browsers. (#565, @M-Adoo)
macros: removed map_writer! and split_writer! macros. (#568, @M-Adoo)
ribir: StateWriter::map_writer and StateWriter::split_writer now only require a writer split function, enhancing both reader and writer split operations. (#568, @M-Adoo)
core: The StateReader no longer supports watching its modifications. Use the StateWatcher trait instead for this functionality. (#556 @M-Adoo)
painter: Changes to BackendPainter APIs. This only affects you if you've implemented a custom painter. (#562 @M-Adoo)

0.2.0 - 2024-05-29

Documented

fix broken links and format the example code (#526 @M-Adoo)
ribir: We no longer auto-generate the built-in list document, as FatObj lists all. Its API documentation is sufficient. (#540 @M-Adoo)
ribir: Added guide "Using Ribir without 'DSL'" (#545 @M-Adoo)
ribir: Added a roadmap. (#550, @M-Adoo)

Breaking

While these are public APIs, they are typically not required for direct use in user code.

core: removed Stateful::on_state_drop and Stateful::unsubscribe_on_drop (#539 @M-Adoo)
core: removed AppCtx::add_trigger_task and AppCtx::trigger_task (#539 @M-Adoo)
core: removed FatObj::unzip and FatObj::from_host (#535 @M-Adoo)
core: removed BuiltinObj. (#535 @M-Adoo)
core: FatObj::new(host: T, builtin: BuiltinObj) -> FatObj::new(host: T)
core: rename DeclareBuilder to ObjDeclarer (#547 @M-Adoo)
core: rename DeclareBuilder::build_declare to ObjDeclarer::finish (#547 @M-Adoo)
core: rename Declare::declare_builder to Declare::declarer (#547 @M-Adoo)
core: Renamed the widget_build method to build for brevity, given its frequent usage. (#549 @M-Adoo)

Features

Support the overlay (@wjian23).

This enhancement simplifies the creation of overlay widgets. It streamlines the addition of any widget to an overlay and offers a more user-friendly API for overlay management
macros: Generates documentation for the builder methods of members in #[derive(Declare)], thus improving IDE support.(#538 @M-Adoo)
core: All built-in widget abilities are now exported on FatObj. (#535 @M-Adoo) You can directly use FatObj to configure built-in widget abilities such as on_click, on_key_down, etc.
```
let _ = FatObj::new(Void)
  .margin(EdgeInsets::all(1.0))
  .on_click(|_, _| { println!("click"); });
```
macros: #[derive(Decalre)] now generates a FatObj<State<T>> instead of State<T>, and supports initialization of all built-in widgets on its ObjBuilder. (#535 @M-Adoo) All pipes used to initialize the field will be unsubscribed when the FatObj is disposed.
```
let row = Row::builder()
  .margin(...)
  .on_click(...)
  .finish(ctx);
```
macros: Introduced simple_declare macro for types that don't use Pipe for initialization. (#535 @M-Adoo)

Changed

core: StateReader now automatically unsubscribes when no writer is present (#532 @wjian23)
core: Consolidated all listener and FocusNode into a MixBuiltin widget (#534 @M-Adoo)
- The MixBuiltin widget reduces memory usage and allows users to utilize all on_xxx event handlers, not only during the build declaration but also after the widget has been built.
core: removed MixBuiltinDeclarer, which is no longer needed. (#538 @M-Adoo)
macros: removed crate ribir_builtin that is no longer needed. (#535 @M-Adoo)

0.1.0 - 2024-03-26

🎉🎉🎉 The first version of Ribir.

The goal of this version of Ribir is to finish the core framework and answer our questions about the feasibility of the design.

We use it to build examples and build some apps for our daily work. And we are satisfied with the experience of using it.

We are very happy to share it with you. We hope you can try it out and give us feedback. But we don't recommend you to use it in production environments yet.

Features

core: control the process of the entire view: compose, build, update, layout and render.
declarative language: not a new language, but a set of Rust macros that easily interact with Rust.
widgets compose system: has four kinds of widgets to support you can implement your own widget in different ways:
- function widget and Compose, from other widgets composition.
- Render, implement your layout and paint anything you want.
- ComposeChild, control the compose logic between parent and child widgets and specify the template of child widgets.
non-intrusive state: convert your data to a listenable state, and update the view according to the change of the state.
layout system: learning and inspired by Flutter Sublinear layout, but not the same.
event system: a composition event system, that supports event bubbling and capture. Allow to compose with any widget, and exists only if you use it.
theme System: support full and inherit/partial theme, so you can use it to override or dynamically switch the theme of the subtree. Include palette, icons, animate transitions, the decoration widget of the widget, etc. In a very rough state and the API will be redesigned soon.
animations: based on state but no side effect animation, it's almost stable in concept, but not many predefined animations yet.
painter： convert the view to the 2D path.
GPU render: GPU backend for the painter, do path tessellation, so that easy to render the triangles in any GPU render engine. A wgpu implementation is provided as the default GPU render engine. Tessellation base on lyon.
text: support basic text typography and IME input, in a usable but rough stage.
widgets: the widgets library provides 20+ basic widgets, but all are in a rough stage, and the API is not stable yet.
examples: counter, storybook, messages, todos, wordle_game, etc.

Documented

introduction: add introduction.md to introduce Ribir and why choose it.
get started: add the get_started series of tutorials to help users get started with Ribir.
