Bevy support doesn't appear to be usable

[chris-janidlo]

I'm new to rust, so I might be missing something, but it appears that there isn't any way to install the bevy plugin, at least through cargo.toml. The bracket-bevy crate doesn't seem to have been uploaded to crates.io:

$ cargo add bracket-bevy
    Updating crates.io index
error: the crate `bracket-bevy` could not be found in registry index.

and the bevy feature in bracket-lib appears to be broken due to asking for the bevy feature from bracket-geometry, which doesn't exist:

[dependencies]
bevy = "0.9.1"
bracket-lib = { version = "0.8.7", features = ["bevy"] }

$ cargo run
    Blocking waiting for file lock on package cache
    Updating crates.io index
error: failed to select a version for `bracket-geometry`.
    ... required by package `bracket-lib v0.8.7`
    ... which satisfies dependency `bracket-lib = "^0.8.7"` of package `<>`
versions that meet the requirements `~0.8` are: 0.8.7, 0.8.3, 0.8.2, 0.8.1, 0.8.0

the package `bracket-lib` depends on `bracket-geometry`, with features: `bevy` but `bracket-geometry` does not have these features.


all possible versions conflict with previously selected packages.

  previously selected package `bevy v0.9.1`
    ... which satisfies dependency `bevy = "^0.9.1"` of package `<>`

failed to select a version for `bracket-geometry` which could resolve this conflict

I'm also fairly new to Rust/Cargo so I don't necessarily have a good answer for why but removing your dependency for bevy = "0.9.1" should solve your issue. My guess is that the bracket-bevy crate only has a dependency for bevy = "0.9" and pinning it to bevy = "0.9.1" is too restrictive.

EDIT: The actual issue is that the main branch of bracket-lib specifies bevy v0.9 however, the bracket-lib that was published has bevy v0.8. If you specify your dependency instead as bracket-lib = { git = "https://github.com/amethyst/bracket-lib", features=["bevy"] }, you can use the version that is in the main branch. Not sure if this is necessarily stable though, but cargo build works.

I'll be back from vacation tomorrow, was going to do some updates. I haven't published the crate (or its dependencies) yet, ran into a few minor issues to resolve. It should work as a git dependency, probably with just bevy "0.9" - haven't had a chance to test 0.9.1 with it yet.

It looks like bracket-lib.features = ["bevy"] is broken.

But here's what works as of right now:

[dependencies]
bevy = { version = "0.9.1" }
bracket-bevy = { git = "https://github.com/amethyst/bracket-lib" }

I have this mostly working now on 0.11.0, just waiting on a pull request. There are a couple of rare stability bugs I detailed that need to get ironed out first however.
