While trying to figure out how to implement a `SystemParam`, I spent a
long time looking for a feature that would do exactly what `Config`
does. I ignored it at first because all the examples I could find used
`()` and I couldn't see a way to modify it.
This is documented in other places, but `Config` is a logical place to
include some breadcrumbs. I've added some text that gives a brief
overview of what `Config` is for, and links to the existing docs on
`FunctionSystem::config` for more details.
This would have saved me from embarrassing myself by filing https://github.com/bevyengine/bevy/issues/2178.

During PR #2046 @cart suggested that the `(): ()` notation is less legible than `_input: ()`. The first notation still managed to slip in though. This PR applies the second writing.
Related to [discussion on discord](https://discord.com/channels/691052431525675048/742569353878437978/824731187724681289)
With const generics, it is now possible to write generic iterator over multiple entities at once.
This enables patterns of query iterations like
```rust
for [e1, e2, e3] in query.iter_combinations() {
// do something with relation of all three entities
}
```
The compiler is able to infer the correct iterator for given size of array, so either of those work
```rust
for [e1, e2] in query.iter_combinations() { ... }
for [e1, e2, e3] in query.iter_combinations() { ... }
```
This feature can be very useful for systems like collision detection.
When you ask for permutations of size K of N entities:
- if K == N, you get one result of all entities
- if K < N, you get all possible subsets of N with size K, without repetition
- if K > N, the result set is empty (no permutation of size K exist)

This can save users from having to type `&*X` all the time at the cost of some complexity in the type signature. For instance, this allows me to accommodate @jakobhellermann's suggestion in #1799 without requiring users to type `&*windows` 99% of the time.
https://github.com/EmbarkStudios/cargo-deny
cargo-deny is a tool that can issue errors for dependency issues, among other:
* security issues in a crate
* duplicated dependencies with different versions
* unauthorised license
Added cargo-deny with an opinionated configuration:
* No middle ground with warnings, either allow or deny
* Not added to Bors, we probably don't want to block a PR on something that may happen from outside
* Different github workflow than CI to run only when Cargo.toml files are changed, or on a schedule
* Each check in its own job to help readability
* Initial config makes Bevy pass all check
Pushing a first commit with commented config to show errors
Fixes the frag shader for unlit materials by correcting the scope of the `#ifndef` to include the light functions. Closes#2190, introduced in #2112.
Tested by changing materials in the the `3d_scene` example to be unlit. Unsure how to prevent future regressions without creating a test case scene that will catch these runtime panics.
This gets rid of multiple unsafe blocks that we had to maintain ourselves, and instead depends on library that's commonly used and supported by the ecosystem. We also get support for glam types for free.
There is still some things to clear up with the `Bytes` trait, but that is a bit more substantial change and can be done separately. Also there are already separate efforts to use `crevice` crate, so I've just added that as a TODO.
`ParallelSystemContainer`'s `system` pointer was extracted from box, but it was never deallocated. This change adds missing drop implementation that cleans up that memory.
The first commit monomorphizes `add_system_inner` which I think was intended to be monomorphized anyway. The second commit moves the type argument of `GraphNode` to an associated type.
Updates the requirements on [gltf](https://github.com/gltf-rs/gltf) to permit the latest version.

This covers issue #2110
It adds the line `.add_system(bevy::input::system::exit_on_esc_system.system())` before `.run()`
to every example that uses a window, so users have a quick way to close the examples.
I used the full name `bevy::input::system::exit_on_esc_system`, I thought it gave clarity about being a built-in system.
The examples excluded from the change are the ones in the android, ios, wasm folders, the headless
examples and the ecs/system_sets example because it closes itself.

There's what might be considered a proper bug in `PipelineCompiler::compile_pipeline()`, where it overwrites the `step_mode` for the passed in `VertexBufferLayout` with `InputStepMode::Vertex`. Due to this some ugly workarounds are needed to do any kind of instancing.
In the somewhat longer term, `PipelineCompiler::compile_pipeline()` should probably also handle a `Vec<VertexBufferLayout>`, but that would be a (slightly) larger PR, rather than a bugfix. And I'd love to have this fix in sooner than we can deal with a bigger PR.

Problem:
- When using the 'as_crate' attribute, if 'as_crate' was empty, the only
error you would get is 'integer underflow'.
Solution:
- Provide an explicit check for the 'as_crate' attribute's token stream
to ensure the formatting is correct.
Note:
- Also reworked 'get_meta' by not making it call 'Manifest::find' twice.
Required by #1429,
- Adds the `Ushort4` vertex attribute for joint indices
- `Mesh::ATTRIBUTE_JOINT_WEIGHT` and `Mesh::ATTRIBUTE_JOINT_INDEX` to import vertex attributes related to skinning from GLTF
- impl `Default` for `Mesh` a empty triangle mesh is created (needed by reflect)
- impl `Reflect` for `Mesh` all attributes are ignored (needed by the animation system)
For review, first iteration of bevy code documentation.
I can continue submitting docs every now and then for relevant parts.
Some challenges I found:
* plugins example had to be commented out, as adding bevy_internal (where plugins reside) would pull in too many dependencies

Changes to get Bevy to compile with wgpu master.
With this, on a Mac:
* 2d examples look fine
* ~~3d examples crash with an error specific to metal about a compilation error~~
* 3d examples work fine after enabling feature `wgpu/cross`
Feature `wgpu/cross` seems to be needed only on some platforms, not sure how to know which. It was introduced in https://github.com/gfx-rs/wgpu-rs/pull/826
Adds an GitHub Action to check all local (non http://, https:// ) links in all Markdown files of the repository for liveness.

Hi, ran into this problem with the derive macro.
It fails trying to derive the Default trait when the asset does not implements it also. This is unnecessary because this plugin does not need that from the asset type, just needs to create the phantom data.
Fixes#2037 (and then some)
Problem:
- `TypeUuid`, `RenderResource`, and `Bytes` derive macros did not properly handle generic structs.
Solution:
- Rework the derive macro implementations to handle the generics.
While trying to reduce load time of gltf files, I noticed most of the loading time is spent transforming bytes into an actual texture.
This PR add asynchronously loading for them using io task pool in gltf loader. It reduces loading of a large glb file from 15 seconds to 6~8 on my laptop
To allow asynchronous tasks in an asset loader, I added a reference to the task pool from the asset server in the load context, which I can use later in the loader.

This alias is to aid people finding the cursor_position function, as the mouse
pressed / moved functionality and naming likely primes people for thinking
of "mouse" before "cursor" when searching the api documentation.
In response to #2023, here is a draft for a PR.
Fixes#2023
I've added an example to show how to use `WithBundle`, and also to test it out.
Right now there is a bug: If a bundle and a query are "the same", then it doesn't filter out
what it needs to filter out.
Example:
```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy( <========= This should not get printed
111,
)
[examples/ecs/query_bundle.rs:57] x = Dummy(
222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
222,
)
```
However, it behaves the right way, if I add one more component to the bundle,
so the query and the bundle doesn't look the same:
```
Print component initated from bundle.
[examples/ecs/query_bundle.rs:57] x = Dummy(
222,
)
Show all components
[examples/ecs/query_bundle.rs:50] x = Dummy(
111,
)
[examples/ecs/query_bundle.rs:50] x = Dummy(
222,
)
```
I hope this helps. I'm definitely up for tinkering with this, and adding anything that I'm asked to add
or change.

I'm using Bevy ECS in a project of mine and I'd like to do world changes asynchronously.
The current public API for creating entities, `Commands` , has a lifetime that restricts it from being sent across threads. `CommandQueue` on the other hand is a Vec of commands that can be later ran on a World.
So far this is all public, but the commands themselves are private API. I know the intented use is with `Commands`, but that's not possible for my use case as I mentioned, and so I simply copied over the code for the commands I need and it works. Obviously, this isn't a nice solution, so I'd like to ask if it's not out of scope to make the commands public?
