# Objective
- There are a few warnings when building Bevy docs for dead links
- CI seems to not catch those warnings when it should
## Solution
- Enable doc CI on all Bevy workspace
- Fix warnings
- Also noticed plugin GilrsPlugin was not added anymore when feature was enabled
First commit to check that CI would actually fail with it: https://github.com/bevyengine/bevy/runs/4532652688?check_suite_focus=true

# Objective And Solution
Add `set_scissor_rect` from wgpu-rs to the `TrackedRenderPass`. wgpu documentation can be found here:
https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_scissor_rect
The reason for adding this is to cull fragments that are outside of the given rect. For my purposes this is extremely useful for UI.
# Objective
Previously, the gilrs system had no explicit relationship to the input
systems. This could potentially cause it to be scheduled after the
input systems, leading to a one-frame lag in gamepad inputs.
This was a regression introduced in #1606 which removed the `PreEvent` stage
## Solution
This adds an explicit `before` relationship to the gilrs plugin,
ensuring that raw gamepad events will be processed on the same frame
that they are generated.
Currently the `ClearPassNode` is not exported, due to an additional `use ...;` in the core pipeline's `lib.rs`. This seems unintentional, as there already is a public glob import in the file.
This just removes the explicit use. If it actually was intentional to keep the node internal, let me know.
# Objective
`KeyCode::*Win` and `KeyCode::*Alt` might be confusing for some Mac users.
## Solution
Added some small documentation to clarify the mappings for those developing on a Mac.
## Additional Context
Related issue: #3240
# Objective
This PR fixes a crash when winit is enabled when there is a camera in the world. Part of #3155
## Solution
In this PR, I removed two unwraps and added an example for regression testing.
# Objective
PBR lighting was broken in the new renderer when using orthographic projections due to the way the depth slicing works for the clusters. Fix it.
## Solution
- The default orthographic projection near plane is 0.0. The perspective projection depth slicing does a division by the near plane which gives a floating point NaN and the clustering all breaks down.
- Orthographic projections have a linear depth mapping, so it made intuitive sense to me to do depth slicing with a linear mapping too. The alternative I saw was to try to handle the near plane being at 0.0 and using the exponential depth slicing, but that felt like a hack that didn't make sense.
- As such, I have added code that detects whether the projection is orthographic based on `projection[3][3] == 1.0` and then implemented the orthographic mapping case throughout (when computing cluster AABBs, and when mapping a view space position (or light) to a cluster id in both the rust and shader code).

This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.
The examples are all ported over and operational with a few exceptions:
* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
# Objective
Fixes#3247
## Solution
- Added docs to `Axis<T>`. This one can be extended @alice-i-cecile
- Added unit tests
- Added `min` and `max` values to the struct. @alice-i-cecile Do we need to these variables?
- Limited `set` method usage with `min` and `max` values

# Objective
Port bevy_ui to pipelined-rendering (see #2535 )
## Solution
I did some changes during the port:
- [X] separate color from the texture asset (as suggested [here](https://discord.com/channels/691052431525675048/743663924229963868/874353914525413406))
- [X] ~give the vertex shader a per-instance buffer instead of per-vertex buffer~ (incompatible with batching)
Remaining features to implement to reach parity with the old renderer:
- [x] textures
- [X] TextBundle
I'd also like to add these features, but they need some design discussion:
- [x] batching
- [ ] separate opaque and transparent phases
- [ ] multiple windows
- [ ] texture atlases
- [ ] (maybe) clipping
# Objective
Make it easier to build and use an asset path with `format!()`. This can be useful for accessing assets in a loop.
Enabled by this PR:
```rust
let monkey_handle = asset_server.get_handle(&format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
```
Before this PR:
```rust
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0").as_str());
```
It's just a tiny improvement in ergonomics, but i ran into it and was wondering why the function does not accept a `String` and Bevy is all about simplicity/ergonomics, right? 😄😉
## Solution
Implement `Into<HandleId>` for `String` and `&String`.
# Objective
- there are a few new versions for `ron`, `winit`, `ndk`, `raw-window-handle`
- `cargo-deny` is failing due to new security issues / duplicated dependencies
## Solution
- Update our dependencies
- Note all new security issues, with which of Bevy direct dependency it comes from
- Update duplicate crate list, with which of Bevy direct dependency it comes from
`notify` is not updated here as it's in #2993
Fills in some gaps we had in our Bevy ECS tracing spans:
* Exclusive systems
* System Commands (for `apply_buffers = true` cases)
* System archetype updates
* Parallel system execution prep
Applogies, had to recreate this pr because of branching issue.
Old PR: https://github.com/bevyengine/bevy/pull/3033
# Objective
Fixes#3032
Allowing a user to create a transparent window
## Solution
I've allowed the transparent bool to be passed to the winit window builder
# Objective
- Checks for NaN in computed NDC space coordinates, fixing unexpected NaN in a fallible (`Option<T>`) function.
## Solution
- Adds a NaN check, in addition to the existing NDC bounds checks.
- This is a helper function, and should have no performance impact to the engine itself.
- This will help prevent hard-to-trace NaN propagation in user code, by returning `None` instead of `Some(NaN)`.
Depends on https://github.com/bevyengine/bevy/pull/3269 for CI error fix.
# Objective
Fixes recent pipeline errors:
```

```
## Solution
- Replaced `IntoIter::new` with `IntoIterator::into_iter`
## Suggestions
For me it looks like two equivalent `Mesh` structs with the same methods. Should we refactor it? Or, they will be different in the near future?

# Objective
- New clippy lints with rust 1.57 are failing
## Solution
- Fixed clippy lints following suggestions
- I ignored clippy in old renderer because there was many and it will be removed soon
A sample implementation of how to have `iter()` work on mutable queries without breaking aliasing rules.
# Objective
- Fixes#753
## Solution
- Added a ReadOnlyFetch to WorldQuery that is the `&T` version of `&mut T` that is used to specify the return type for read only operations like `iter()`.
- ~~As the comment suggests specifying the bound doesn't work due to restrictions on defining recursive implementations (like `Or`). However bounds on the functions are fine~~ Never mind I misread how `Or` was constructed, bounds now exist.
- Note that the only mutable one has a new `Fetch` for readonly as the `State` has to be the same for any of this to work

This pull request aims to solve the issue of a lack of documentation in the enum WindowMode
# Objective
- Fixes#3136
## Solution
- Added a few lines of documentation that should document what the enum does better
# Problem
Let's say I am writting a simple bevy plugin, and I want to depend on `bevy_ecs` crate instead of depending on the full `bevy`.
So I write the following:
*Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }
```
*lib.rs*:
```rust
use bevy_ecs::prelude::*;
#[derive(Debug, Default, Component)
pub struct MyFancyComponent;
```
So far, so good. Everything works. But let's say I want to write some examples for using my plugin. And for theses I'd like to use the `bevy` crate, so that I can write complete examples (rendering stuff, etc.) that are simple and look like what the consumer of my plugin will do (`use bevy::prelude::*` and `DefaultPlugins`)
So I amend my *Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }
[dev-dependencies]
bevy = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886", default-features = false }
```
And that leads to a complilation error
```
error[E0433]: failed to resolve: use of undeclared crate or module `bevy`
```
Basically, because `bevy` is in the `dev-dependencies`, the macro (of the production code) decides to use the `bevy::ecs` path instead of `bevy_ecs`. But `bevy` is not available there.
## Solution
This PR fixes the problem. I amend the macro utility responsible of finding the path of a module.
If we try to find a path, we first test if this correspond to a crate that the user directly depend on. (Like, if we search for `bevy_ecs`, we first check if there is a `bevy_ecs` dependency). If yes, we can depend on that directly. Otherwise, we proceed with the existing logic (testing `bevy` and `bevy_internal`)
## Shader Imports
This adds "whole file" shader imports. These come in two flavors:
### Asset Path Imports
```rust
// /assets/shaders/custom.wgsl
#import "shaders/custom_material.wgsl"
[[stage(fragment)]]
fn fragment() -> [[location(0)]] vec4<f32> {
return get_color();
}
```
```rust
// /assets/shaders/custom_material.wgsl
[[block]]
struct CustomMaterial {
color: vec4<f32>;
};
[[group(1), binding(0)]]
var<uniform> material: CustomMaterial;
```
### Custom Path Imports
Enables defining custom import paths. These are intended to be used by crates to export shader functionality:
```rust
// bevy_pbr2/src/render/pbr.wgsl
#import bevy_pbr::mesh_view_bind_group
#import bevy_pbr::mesh_bind_group
[[block]]
struct StandardMaterial {
base_color: vec4<f32>;
emissive: vec4<f32>;
perceptual_roughness: f32;
metallic: f32;
reflectance: f32;
flags: u32;
};
/* rest of PBR fragment shader here */
```
```rust
impl Plugin for MeshRenderPlugin {
fn build(&self, app: &mut bevy_app::App) {
let mut shaders = app.world.get_resource_mut::<Assets<Shader>>().unwrap();
shaders.set_untracked(
MESH_BIND_GROUP_HANDLE,
Shader::from_wgsl(include_str!("mesh_bind_group.wgsl"))
.with_import_path("bevy_pbr::mesh_bind_group"),
);
shaders.set_untracked(
MESH_VIEW_BIND_GROUP_HANDLE,
Shader::from_wgsl(include_str!("mesh_view_bind_group.wgsl"))
.with_import_path("bevy_pbr::mesh_view_bind_group"),
);
```
By convention these should use rust-style module paths that start with the crate name. Ultimately we might enforce this convention.
Note that this feature implements _run time_ import resolution. Ultimately we should move the import logic into an asset preprocessor once Bevy gets support for that.
## Decouple Mesh Logic from PBR Logic via MeshRenderPlugin
This breaks out mesh rendering code from PBR material code, which improves the legibility of the code, decouples mesh logic from PBR logic, and opens the door for a future `MaterialPlugin<T: Material>` that handles all of the pipeline setup for arbitrary shader materials.
## Removed `RenderAsset<Shader>` in favor of extracting shaders into RenderPipelineCache
This simplifies the shader import implementation and removes the need to pass around `RenderAssets<Shader>`.
## RenderCommands are now fallible
This allows us to cleanly handle pipelines+shaders not being ready yet. We can abort a render command early in these cases, preventing bevy from trying to bind group / do draw calls for pipelines that couldn't be bound. This could also be used in the future for things like "components not existing on entities yet".
# Next Steps
* Investigate using Naga for "partial typed imports" (ex: `#import bevy_pbr::material::StandardMaterial`, which would import only the StandardMaterial struct)
* Implement `MaterialPlugin<T: Material>` for low-boilerplate custom material shaders
* Move shader import logic into the asset preprocessor once bevy gets support for that.
Fixes#3132
This is a squash-and-rebase of @Ku95's documentation of the new renderer onto the latest `pipelined-rendering` branch.

# Objective
- Document that the error codes will be rendered on the bevy website (see bevyengine/bevy-website#216)
- Some Cargo.toml files did not include the license or a description field
## Solution
- Readme for the errors crate
- Mark internal/development crates with `publish = false`
- Add missing license/descriptions to some crates
- [x] merge bevyengine/bevy-website#216
# Objective
bevy_ecs has several compile_fail tests that assert lifetime safety. In the past, these tests have been green for the wrong reasons (see e.g. #2984). This PR makes sure, that they will fail if the compiler error changes.
## Solution
Use [trybuild](https://crates.io/crates/trybuild) to assert the compiler errors.
The UI tests are in a separate crate that is not part of the Bevy workspace. This is to ensure that they do not break Bevy's crater builds. The tests get executed by the CI workflow on the stable toolchain.
# Objective
Document that `AssetServer::load()` is asynchronous.
## Solution
Document that `AssetServer::load()` is asynchronous, and that the asset
will not be immediately available once the call returns. Instead,
explain that the user must call `AssetServer::get_load_state()` to
monitor the loading state of an asset.
# Objective
- `bevy_ecs` exposes as an optional feature `bevy_reflect`. Disabling it doesn't compile.
- `bevy_asset` exposes as an optional feature `filesystem_watcher`. Disabling it doesn't compile. It is also not possible to disable this feature from Bevy
## Solution
- Fix compilation errors when disabling the default features. Make it possible to disable the feature `filesystem_watcher` from Bevy
# Objective
- Update vendor crevice to have the latest update from crevice 0.8.0
- Using https://github.com/ElectronicRU/crevice/tree/arrays which has the changes to make arrays work
## Solution
- Also updated glam and hexasphere to only have one version of glam
- From the original PR, using crevice to write GLSL code containing arrays would probably not work but it's not something used by Bevy
# Objective
Clarify the fact that setting the `RUST_LOG` environment variable
overrides any setting from the `LogSettings` resource.
## Solution
Update docstring comment for `LogSettings`.
- Requires #2997
- Removes `wasm_audio` feature as discussed in #2397
- Closes only task in #2479
Open questions:
Should we enable wasm audio by default or only when building for wasm using `cfg`?
Maybe there should be a global wasm feature for bevy?
# Objective
Fixes#2823.
## Solution
This PR adds notes to the `HashMap` and `HashSet` docs explaining why `HashMap::new()` (resp. `HashSet::new()`) is not available, and guiding the user toward using the `Default` implementation for an empty collection.
# Objective
- Improve error descriptions and help understand how to fix them
- I noticed one today that could be expanded, it seemed like a good starting point
## Solution
- Start something like https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes
- Remove sentence about Rust mutability rules which is not very helpful in the error message
I decided to start the error code with B for Bevy so that they're not confused with error code from rust (which starts with E)
Longer term, there are a few more evolutions that can continue this:
- the code samples should be compiled check, and even executed for some of them to check they have the correct error code in a panic
- the error could be build on a page in the website like https://doc.rust-lang.org/error-index.html
- most panic should have their own error code
Mention the fact that the UI layout system is based on the CSS layout
model through a docstring comment on the `Style` type.
# Objective
Explain to new users that the Bevy UI uses the CSS layout model, to lower the barrier to entry given the fact documentation (book and code) is fairly limited on the topic.
## Solution
Fix as discussed with @alice-i-cecile on #2918.
# Objective
Set initial position of the window, so I can start it at the left side of the view automatically, used with `cargo watch`
## Solution
add window position to WindowDescriptor
