retil-interactions v0.18.9

retil-interactions

• this package should be completely free of styles or integrations for specific, style libraries, but does contain useStyles, which takes a style object of various forms possibly including named selectors, and replaces any named selectors with selectors from the context.

• this package should contain usePopupTrigger, usePopup

• things to test:

  • can we configure for usage with styled-components using a single global Provider? we'd probably need to configure a way of patching theme context, as well as the stuff to actually patch it with. we'd want a separate retil-interactions-styled-components package to handle this

    For our surfaces, we can probably use constant class names instead of using class names generated for empty styled components. e.g. an AnchorSurface could have a "retil-anchor-surface" classname, and we could just build our selectors based on that. No need for fancy styled components stuff.

    For , we can actually use a :first-child selector to pick out whatever control is the first child, which allows us to select anything.

• why may want to then export reset styles for anchors, buttons, inputs, etc. along with UnstyledAnchor, UnstyledButton, UnstyledInput, etc. in a separate package.

• surface and control primitives

  these render individual DOM elements, setting up context such that embedded styled components can target interaction states like hover, disabled, etc.

  • <DivSurface activated onPress?>
    • you'll need to manually set aria roles, as I don't want to make assumptions

  exported by retil-router

  • - will not change interaction state based on url

  • - sets up default "activated" state based on url

  • useControlRef() - returns the ref created by ControlInteractionProvider

  • <ControlDiv control decorators? />

    • "control" is an element that will be rendered as the first child of this component. e.g. , , , etc.
    • we'll look for both :focus and :focus-within on the :first-child selector, and put these selectors in the selector context of subsequent children. note that :focus-within won't work on older browsers, so for controls with nested markup where focus may be applied to internal elements, it may not work
    • we'll also pass in any ref provided by ControlProvider to control, ensuring that this can be used with control boundary surfaces, etc.
    • rendered in a wrapper. could create non-div wrappers too, but we do need to have some kind of container so that we can use the :first-child selector to pick out the control
    • can be used outside of a ControlProvider, allowing interaction styles to be applied using pure CSS pseudoselectors and no extra event handlers.

  • custom controls can be built that don't need to be wrapped in ControlContainer. they just need to handle the state passed down by ControlProvider, e.g. allow it to focus the control, and pass the control ref to whatever part of the dom events should be bound to.

  • usePopup({ trigger: boolean | PopupTrigger }): { style, connectTrigger, connectReaction, etc. }

    • wraps a popper and a popup trigger
    • can still be focused even if byFocus is not set, so long as the the TriggerSurface is focusable
    • connectTrigger sets the popper reference and popup trigger
    • connectReaction sets the popup
    • if this is rendered inside a , then any surfaces within the popup will delegate focus to the control itself, allowing you to click the surfaces within the popup without removing focus from a trigger wrapping the control input.

  • usePopupContext()

  • a control is free to move focus around inside of it, and to move the tabIndex of any of its internal markup around. controls are basically black boxes. the only constraint is that the control must provide functions to focus/blur it, and it must render the control context ref on an element that events should be bound to.

• need to add modal interactions too...
