//! StereoKit-rust is a binding for the [StereoKit](https://StereoKit.net) C API.
//! If the name of this crate contains "_rust" (not great for a Rust crate, we agree) it is to emphasize the fact that
//! StereoKit is first and foremost a C, C++, C# project.
//! StereoKit allows you to create VR/MR applications with ease on every headset platforms that run OpenXR.

//! If you already know the name of what you are looking for, the fastest way to
//! find it is to use the <a href="#" onclick="window.searchState.focus();">search
//! bar</a> at the top of the page.
//! Otherwise, you may want to jump to one of these useful sections:

//!
//! # Installation:
//! StereoKit-rust is a binding and therefore requires some tools and libraries to compile StereoKitC:
//! ### On `Windows`:
//!   - Considering that you have already installed "`Visual Studio Build Tools 2022(Developpment Desktop C++)`" in order to
//!     have `Rust` compiling with `stable-????-pc-windows-msvc` toolchain.
//!   - Get the following tools and dev libraries : "`Git`", "`CMake`" and "`DotNet SDK v8+`".
//!
//! ### On `Linux`:
//!   - Considering that you have already installed `Rust` with `stable-?????-unknown-linux-gnu` toolchain and the linux package
//!     `build-essential`.
//!   - Get the following tools and dev libraries : `git` `clang` `cmake` `lld` `ninja-build` `libx11-dev`
//!     `libxfixes-dev` `libegl-dev` `libgbm-dev` `libfontconfig-dev` `libxkbcommon-x11-dev`.
//!
//! Installing the stereokit_rust tools with `cargo install -F no-event-loop stereokit-rust` should help you to check
//! the missing dependencies.
//!
//! # Usage
//! You have to chose between `event-loop` and `no-event-loop` features. The feature `no-event-loop` is the
//! lighter but you can't use the [`framework`].
//!
//! Using `event-loop` your `Cargo.toml` should contain the following lines:
//! ```toml
//! [lib]
//! crate-type = ["lib", "cdylib"]
//!
//! [dependencies]
//! stereokit-rust = { version = "0.4.0", features= ["event-loop"] }
//! winit = { version = "0.30", features = [ "android-native-activity" ] }
//!
//! [target.'cfg(target_os = "android")'.dependencies]
//! stereokit-rust = { version = "0.4.0" , features = ["event-loop", "build-dynamic-openxr"] }
//! log = "0.4"
//! android_logger = "0.15"
//! ndk-context = "0.1.1"
//! ndk = "0.9.0"
//! ```
//!
//! # Examples
//! Here is a simple "Hello World" StereoKit-rust app for all platforms:
//! ```bash
//! cargo new --lib vr_app
//! cd vr_app
//! ```
//!
//! In `src/bin/main_vr_app.rs`, if you intend to build a PC VR/MR app:
//! ```ignore
//! #[allow(dead_code)]
//! #[cfg(not(target_os = "android"))]
//! fn main() {
//!     use stereokit_rust::sk::{SkSettings, Sk};
//!     use vr_app::the_main;
//!     // Initialize StereoKit with default settings
//!     let mut settings = SkSettings::default();
//!     settings.app_name("Test");
//!     # settings.mode(stereokit_rust::sk::AppMode::Offscreen);
//!     let (sk, event_loop) = settings.init_with_event_loop()
//!         .expect("Should initialize StereoKit");
//!     the_main(sk, event_loop);
//!     Sk::shutdown();
//! }
//!
//! #[allow(dead_code)]
//! #[cfg(target_os = "android")]
//! //fake main fn for android as entry is lib.rs/android_main(...)
//! fn main() {}
//!
//! # use stereokit_rust::prelude::*;
//! # use winit::event_loop::EventLoop;
//! # pub fn the_main(sk: Sk, event_loop: EventLoop<StepperAction>) {}
//! ```
//!
//! In `src/lib.rs` where you can remove the `target_os = "android" code` if you don't want to build for Android:
//! ```ignore
//! use stereokit_rust::{framework::SkClosures, prelude::*, sk::Sk, ui::Ui};
//! use winit::event_loop::EventLoop;
//!
//! #[cfg(target_os = "android")]
//! use winit::platform::android::activity::AndroidApp;
//!
//! #[unsafe(no_mangle)]
//! #[cfg(target_os = "android")]
//! pub fn android_main(app: AndroidApp) {
//!     use stereokit_rust::sk::SkSettings;
//!     // Initialize StereoKit with default settings
//!     let mut settings = SkSettings::default();
//!     settings.app_name("Test");
//!     android_logger::init_once(
//!         android_logger::Config::default()
//!               .with_max_level(log::LevelFilter::Debug)
//!               .with_tag("STKit-rs"),
//!     );
//!     let (sk, event_loop) = settings.init_with_event_loop(app).unwrap();
//!     the_main(sk, event_loop);
//! }
//!
//! /// Main function for All!
//! pub fn the_main(sk: Sk, event_loop: EventLoop<StepperAction>) {
//!     // Create a grabbable window with a button to exit the application
//!     let mut window_pose = Ui::popup_pose([0.0, -0.4, 0.0]);
//!     // Main loop
//!     SkClosures::new(sk, |sk, _token| {
//!         // Exit button
//!         Ui::window_begin("Hello world!", &mut window_pose, None, None, None);
//!         if Ui::button("Exit", None) {
//!             sk.quit(None)
//!         }
//!         Ui::window_end();
//!     })
//!     .run(event_loop);
//! }
//! ```

//! # How to build and test your application:
//!
//! * [Building your PC VR/MR app](#building-your-pc-vrmr-app).
//! * [Building your Android VR/MR app](#building-your-android-vrmr-app).
//! * [Building your Windows GNU PC VR/MR app](#building-your-windows-gnu-pc-vrmr-app).
//! * [Building your Linux AARCH64 PC VR/MR app](#building-your-linux-aarch64-pc-vrmr-app).
//! * [Building your Linux X86_64 PC VR/MR app](#building-your-linux-x86_64-pc-vrmr-app).
//!
//! ## Building your PC VR/MR app:
//! * Launch `cargo run --bin main_vr_app` to compile and run your app in debug mode on your PC with or without a headset.
//!   (using Wayland on Linux may require to unset temporarily the DISPLAY variable: `DISPLAY= cargo run`)
//! * Launch `cargo build_sk_rs --bin main_vr_app <build_directory>` to compile your app and assets in release mode for your PC.
//!
//! To test with your headset, make sure you have [OpenXR installed](https://www.khronos.org/openxr/) with an active
//! runtine (SteamVR, Monado, WiVRn, ALVR ...).
//!
//! ## Building your Android VR/MR app:
//! This can be done from a PC running Windows, Mac or Linux:
//! * Install [sdkmanager](https://developer.android.com/studio/command-line/sdkmanager) (or Android Studio if you
//!   intend to use it). You'll need a Java JDK (v17 is fine).
//! * Using sdkmanager, install platform-tools(v32), latest build-tools and the latest ndk.
//! * Set ANDROID_HOME environment variable to its path (this path contains the `build_tools` directory).
//! * Set the NDK path (which ends with it's version number) into the ANDROID_NDK_ROOT environment variable.
//! * Install [Ninja](https://ninja-build.org/)
//! * Check that `adb` ($ANDROID_HOME/platform_tools/adb) is connecting to your headset.
//! * Download the target: `rustup target add aarch64-linux-android` for most existing android headsets.
//! * Create a keystore for signing your app (using keytool or Android Studio).
//! ##### If you don't need some java/kotlin code, you can use cargo-apk  (cargo-xbuild is an alternative but lacks some documentation):
//!   - Install: `cargo install cargo-apk`.
//!   - The manifest file will be generated from the `Cargo.toml` (see the `package.metadata.android` section). Here are
//!     some examples:
//!     - [StereoKit-template](https://github.com/mvvvv/stereokit-template/blob/main/Cargo.toml#L27)
//!     - [StereoKit-rust](https://github.com/mvvvv/StereoKit-rust/blob/master/Cargo.toml#L77)
//!   - Create a res directory with the icons of your app (i.e. with <https://icon.kitchen>)
//!   - Set the path and password to your keystore in the `Cargo.toml` [package.metadata.android.signing.release] or
//!     in the `CARGO_APK_RELEASE_KEYSTORE` and  `CARGO_APK_RELEASE_KEYSTORE_PASSWORD` environment variables.
//!   - Launch the debug on your headset: `cargo apk run --lib`
//!   - Generate the release apk: `cargo apk build --lib --release`. The apk will be in `target/release/apk/`.
//! ##### Otherwise, you have to use Gradle with cargo-ndk:
//!   - Install: `cargo install cargo-ndk`.
//!   - Clone or extract a ZIP of [gradle template](https://github.com/mvvvv/stereokit-template/tree/gradle).
//!   - Name your project in the `package.name` entry in `Cargo.toml`.
//!   - Set `cargo.libName` (same as `package.name` from `Cargo.toml`), `android.applicationId` and `android.main` in
//!     `gradle.properties`.
//!   - In `app/src/main/AndroidManifest.xml` delete or modify the path and package name of `MainActivity.java` (your
//!     choice impacts android.main ↑ and android:hasCode attribute).
//!   - Replace the content of the res directory with the icons of your app (i.e. with <https://icon.kitchen>)
//!   - Store your keystore values in one of the hidden gradle properties files (ie. `~/.gradle/gradle.properties`)
//!     to store and forget the confidential values:
//!     - RELEASE_STORE_FILE=/home/**/**/my_release_key.keystore
//!     - RELEASE_STORE_PASSWORD=******
//!     - RELEASE_KEY_ALIAS=*****
//!     - RELEASE_KEY_PASSWORD=******
//!   - If any, remove the .git folder.
//!   - Launch the debug on your connected headset:
//!     - On Windows, launch: `./gradlew.bat run && cmd /c logcat.cmd` or `(./gradlew.bat run) -and (cmd /c logcat.cmd)`
//!     - On others, launch: `./gradlew run && ./logcat.cmd`
//!   - Generate the release apk: `./gradlew buildRelease`. The apk will be in `app/build/outputs/apk/release`
//!
//! ## Building your Windows GNU PC VR/MR app:
//! Thanks to Steam Proton, you can run your Windows exe on Linux. It's even better than native build thanks to D3D11
//! to Vulkan translation. Knowing that, we work to build Windows .exe files on Linux using GNU toolchain.
//!
//! Build your app for Windows_x64 using GNU toolchain from Linux and Windows (and probably Mac):
//! * Install mingw-w64 (MSYS2 on windows).
//! * Add the `Rust` target gnu for windows:`rustup target add x86_64-pc-windows-gnu`
//! * On 'Non Windows OS': we need wine to compile the shaders:
//!   - Add i386 architecture (i.e. `sudo dpkg --add-architecture i386` on Ubuntu).
//!   - Install wine and winetricks.
//!   - Install needed tools and libs: `winetricks corefonts d3dx9 d3dcompiler_47 dxvk`.
//! * Create a directory where necessary libs will be stored (i.e. ../x64-mingw-libs/) then add a link to the DLLs or
//!   static libs (*.a) the build will need after or during its creation. Example on Ubuntu 24.XX:
//!   - If you want to use DLLs:
//!      - `ln -s /usr/lib/gcc/x86_64-w64-mingw32/13-win32/libgcc_s_seh-1.dll ../x64-mingw-libs/`
//!      - `ln -s /usr/lib/gcc/x86_64-w64-mingw32/13-win32/libstdc++-6.dll ../x64-mingw-libs/`
//!   - If you want to use static libs:
//!      - `ln -s /usr/lib/gcc/x86_64-w64-mingw32/13-win32/libgcc_eh.a ../x64-mingw-libs/`
//!      - `ln -s /usr/lib/gcc/x86_64-w64-mingw32/13-win32/libstdc++.a ../x64-mingw-libs/`
//! * Launch: `cargo build_sk_rs --bin main_vr_app --x64-win-gnu ../x64-mingw-libs/ <the path of your exportable repository>`
//! * To run your_app.exe on Linux:
//!   - Add a non-steam game to your library then launch it when WiVRn or SteamVR are started.
//!   - If you only need the simulator: `wine your_app.exe`.
//!
//! ## Building your Linux aarch64 PC VR/MR app:
//! If you are on aarch64 Linux, you just have to follow the instructions in [`Building your PC VR/MR app`](#building-your-pc-vrmr-app).
//! If you are on a x86_64 architecture you are able to cross-compile your app for aarch64:
//! * Install g++-aarch64-linux-gnu
//! * Get the libraries `libx11-dev:arm64` `libxfixes-dev:arm64` `libegl-dev:arm64` `libgbm-dev:arm64` `libfontconfig-dev:arm64`.
//!   On Ubuntu 24:XX this can be done by adding a foreign architecture `dpkg --add-architecture arm64` with depot
//!   `http://ports.ubuntu.com/ubuntu-ports`. To avoid errors during `apt update` you'll have to specify the architectures
//!   of all depots in `/etc/apt/sources.list.d/ubuntu.sources`
//! * Add the rust target aarch64 for Linux:`rustup target add aarch64-unknown-linux-gnu`
//! * Add a section `[target.aarch64-unknown-linux-gnu]` in your config.toml for setting `linker = "aarch64-linux-gnu-gcc"`
//! * Launch `cargo build_sk_rs --bin main_vr_app --aarch64-linux <the path of your exportable repository>`
//!
//! ## Building your Linux x86_64 PC VR/MR app:
//! If you are on x86_64 Linux, you just have to follow the instructions in [`Building your PC VR/MR app`](#building-your-pc-vrmr-app).
//! If you are on aarch64 architecture you should be able to cross-compile for x86_64:
//! (This hasn't been tested yet, if you are interested in testing it, please let us now)
//! * Install g++-x86-64-linux-gnu
//! * Get the libraries `libx11-dev:amd64` `libxfixes-dev:amd64` `libegl-dev:amd64` `libgbm-dev:amd64` `libfontconfig-dev:amd64`.
//!   On Ubuntu 24:XX this can be done by adding a foreign architecture `dpkg --add-architecture amd64` with depot
//!   `http://ports.ubuntu.com/ubuntu-ports`. To avoid errors during `apt update` you'll have to specify the architectures
//!   of all depots in `/etc/apt/sources.list.d/ubuntu.sources`
//! * Add the rust target aarch64 for linux:`rustup target add x86_64-unknown-linux-gnu`
//! * Add a section `[target.x86_64-unknown-linux-gnu]` in your config.toml for setting `linker = "x86_64-linux-gnu-gcc"`
//! * Launch `cargo build_sk_rs --bin main_vr_app --x64-linux <the path of your exportable repository>`.
