What's the point of passing onOpenChange, open, and other props explicitly if they are a part of ...props?

[atomiks]

Yeah, you're right. Forgot that the linting allows unused variables (as they need to be destructured to be documented)

[atomiks]

Well not anymore with our latest linting config:

/tmp/base-ui/packages/react/src/popover/root/PopoverRoot.tsx
16:11 error 'defaultOpen' is assigned a value but never used @typescript-eslint/no-unused-vars
16:24 error 'open' is assigned a value but never used @typescript-eslint/no-unused-vars
16:30 error 'onOpenChange' is assigned a value but never used @typescript-eslint/no-unused-vars
...

Some cases could be simplified even more (less destructuring) if we passed all the props to hooks as they are, without providing default values on a component level. I'm also thinking about reconsidering the context access pattern we use and having the hooks instead of components read context values. This way, we might not need to create new objects just to pass data to hooks as a single parameter.

Are you referring to useAnchorPositioning or other ones too? A lot of the defaults are the same for that one, although a couple are different for each component (like side). Also, doesn't the documentation require the destructuring?

I mean all our hooks in general (especially the simpler ones). In cases like https://github.com/mui/base-ui/blob/master/packages/react/src/popover/title/PopoverTitle.tsx#L25, we might simplify passing parameters by passing the whole props object to usePopoverTitle and moving usePopoverRootContext to the hook. I see that the Select hooks already read context. The perf gains won't be huge, so it's likely not worth going through the whole codebase, but it could be something to consider in future components.

Yup, we'd have to change the docgen if we wanted to do this.
