#[cfg(platform)] for Feature Flags
Feature Request
Dioxus runs on many platforms and OS, and I'm sure with different versions of the same Operating Systems or in case of the web then multiple Browsers / Renderers, this creates alot of confusion when one has to chase caniuse.com for Web and other vendor specific docs to handle for specific OS
Implement Suggestion
Dixous can take this a bit further for help with DX.
We can easily have multiple platforms: "web", "blitz", "native", "desktop", "mobile", "xr" and so forth (similar to #[cfg(feature = "")])
Example API:
Web Browser / User Agent: #[cfg(platform = "web", browser = "<USER_AGENT>")]
iOS: #[cfg(platform = "mobile", os = "ios", min_version = "18.3")]
iPadOS: #[cfg(platform = "tablet", os = "ipados")]
Desktop (i.e. Windows 8 to 11): #[cfg(platform = "desktop", os = "windows", min_version = "8", max_version = "10")]
Creating fine-grained cfg handling for platform specific features, we could also make the second and any consecutive attributes optional.
cfg is a builtin macro, so we can't modify the behavior, but we do already support conditionally compiling blocks of code based on each dioxus platform with these macros in the dioxus-config-macro crate
That's amazing, perhaps we can extend those macros to help achieve the functionality described in the original issue
