Support for upcoming release / main branch

[miketwenty1]

Is there any plans to support 0.11 before it's released? .add_plugin(EguiPlugin) doesn't work with the main branch of bevy currently.

[vladbat00]

Hey, there's a fork maintaining the 0.11 support: #188

[miketwenty1]

@mvlabat @Vrixyz

How would one utilize the Vrixyz fork in Cargo.toml?
I've tried a couple things and I'm getting errors:

bevy_egui = { git = "https://github.com/Vrixyz/bevy_egui", branch = "bevy-main" }

Is there an example Cargo.toml I look at to understand how to properly specify the right dependencies in the right way?

[Vrixyz]

I tested against bevyengine/bevy@cdaae01c.

If you have more dependencies, you might want to patch rather than specifying the dependency directly:

Keep:

bevy_egui = "*"

But add a patch:

[patch.crates-io]
bevy_egui = { git = 'https://github.com/Vrixyz/bevy_egui', branch = 'bevy-main' }

I'll update my fork eventually :)

edit: I updated the fork against bevy as of 10f5c9206847ae01b8dc833c2680562e7bd46664

@Vrixyz fwiw, I'm getting the same error against bevy's main branch with the modifications you referenced

Thanks for providing the logs, you're not testing with my latest commit, https://github.com/Vrixyz/bevy_egui?branch=bevy-main#473ceb60 should be https://github.com/Vrixyz/bevy_egui?branch=bevy-main#74c11d35

[Vrixyz]

running cargo update should refresh and pull the latest dependencies

[miketwenty1]

@Vrixyz I'm getting a new error when trying to use the plugin.

I tried both the old and new syntax of .add_plugin and .add_plugins. (bevy recently deprecated the .add_plugin it seems)

.add_plugins(EguiPlugin)

error[E0277]: the trait bound `EguiPlugin: bevy_app::plugin::sealed::Plugins<_>` is not satisfied
   --> src/main.rs:106:22
    |

    |          |
    |          required by a bound introduced by this call

Edit: I was using the wrong version of your code, I switched back to the bevy-main branch and I no longer get this error.

Edit2: @Vrixyz
I think Rust Analyzer was playing tricks on me earlier and I got confused.
Do you have an example repo that is able to compile your version of bevy egui that I can learn from?

[Vrixyz]

Sorry I don't have particular example repository for you to study, you can check the updated examples on my branch though.

[miketwenty1]

@Vrixyz I believe I have some confusion on my end on how this works. I am able to run: cargo run --example ui on your branch.

If I try to take the ui.rs code in examples and run with my own Cargo.toml with main.rs, I'll get errors like this:

error[E0277]: the trait bound `EguiSettings: bevy::prelude::Resource` is not satisfied
   --> src/main.rs:60:24
    |
60  |     mut egui_settings: ResMut<EguiSettings>,
    |                        ^^^^^^^^^^^^^^^^^^^^ the trait `bevy::prelude::Resource` is not implemented for `EguiSettings`

My main.rs is the same as ui.rs in examples.

My Cargo.toml

[package]
name = "testegui"
version = "0.1.0"
edition = "2021"


[dependencies]
bevy = { git = "https://github.com/bevyengine/bevy", rev = "10f5c9206847ae01b8dc833c2680562e7bd46664" } 
bevy_egui = { git = 'https://github.com/Vrixyz/bevy_egui', rev = "74c11d35469d6ee35279b49a773946f7b638e568" } 


[patch.crates-io]

[workspace]
resolver = "2"

[profile.dev]
opt-level = 1

[profile.dev.package."*"]
opt-level = 3

My .cargo/config.toml

[target.wasm32-unknown-unknown]
runner = "wasm-server-runner"

[build]
rustflags = ["--cfg=web_sys_unstable_apis"]

I don't believe me targeting wasm is an issue here, as my rust analyzer/compiler is complaining. I feel I'm missing a key idea with how dependencies work with rust, perhaps you could help educate on how I can minimumally config a Cargo.toml to run an example independent of the repo?

[Vrixyz]

From your info, I can reproduce the issue 👍 :

I suspected multiple bevy version being used, to make sure I ran:
$ cargo tree -i bevy

It confirmed my suspicion:

error: There are multiple `bevy` packages in your project, and the specification `bevy` is ambiguous.
Please re-run this command with `-p <spec>` where `<spec>` is one of the following:
  https://github.com/bevyengine/bevy.git#bevy@0.11.0-dev
  https://github.com/bevyengine/bevy#0.11.0-dev

maybe the .git from my PR is enough to confuse dependency reconciliation, or maybe the difference between you specifying the rev=.. vs me specifying branch=main.. ; not sure, in the meantime I got a cargo.toml version that works:

[package]
name = "testegui"
version = "0.1.0"
edition = "2021"

[dependencies]
bevy = "0.11.0-dev"
bevy_egui = "*"

[patch.crates-io]
bevy = { git = 'https://github.com/bevyengine/bevy.git', branch = 'main' }
bevy_egui = { git = 'https://github.com/Vrixyz/bevy_egui', branch = 'bevy-main' }

[Zeenobit]

@Vrixyz Thanks for updating this! Using the patch in your post, I get the following error in my project:
"the trait bevy::prelude::Component is not implemented for bevy_egui::EguiContext"

This is my Cargo.toml:

[dependencies]
bevy = { version = "0.11.*", default-features = false }
bevy_egui = { version = "*", features = [ "immutable_ctx" ] }

[patch.crates-io]
bevy_egui = { git = "https://github.com/Vrixyz/bevy_egui", branch = "bevy-main" }

Any clues?

Edit: Solved it. I didn't realize I had to put the patch snippet in the root Cargo.toml. Thanks again for this!
