Bevy Log File Output

[samcarey]

Is there a way to send Bevy logs to a file?
Preferably I'd like to print to both console and the file.

You can use your own tracing subscriber using bevy::utils::tracing::subscriber::set_global_default(). Make sure to disable the LogPlugin though as tracing only allows setting a global subscriber once. See https://github.com/bevyengine/bevy/blob/main/crates/bevy_log/src/lib.rs for the way the current console printing is implemented.

I do think we should make it easier to set up common log configurations like logging to files. Feel free to open an issue for that.

OK thanks! I was able to get something working like you said, and I opened #5233.
