Which usage does the ReferenceProps mean?

[LoTwT]

Here is the definition of the Props type which is returned by analyzeSFC.

I know three usages of the defineProps as following:

1. defineProps(["msg"])
2. defineProps({ msg: String })
3. defineProps<{ msg: string }>()

I think the TSProps is 3 and the ObjectProps may be 2 .

Which usage does the ReferenceProps type mean?
Does 1 also mean the ObjectProps?

Array is also essentially an object, so cases 1 and 2 are ObjectProps. ReferenceProps stands for defineProps(variable) and applies to all non-literal expressions.

• defineProps(variable)
• defineProps(generator())

However, they're not implemented yet. Only TS-type declaration is supported.

Except for the feature hoistStatic of vue-macros, does vue support ReferenceProps itself currently?
I'd like to support ObjectProps and ReferenceProps. Are there some caveats I should pay more attention to?

[sxzz]

Yes. Vue core supported. For example:

import { buttonProps } from './foo'
defineProps(buttonProps)
