Description

To test: type "Gutenberg" in a RichText field. The word will be highlighted if it's the first occurrence, and if the "Block" sidebar is open. Now remove a letter, and highlighting will be gone. Add it back to add highlighting and go to the "Document" sidebar. Highlighting will be gone. It depends on the sidebar state.

Example plugin code:

wp.richText.registerFormatType( 'plugin/annotation', {
	title: 'invisible',
	tagName: 'mark',
	className: 'annotation',
	__experimentalGetPropsForEditableTreePreparation( select ) {
		return {
			isEnabled: select( 'core/edit-post' ).getActiveGeneralSidebarName() === 'edit-post/block',
		};
	},
	__experimentalCreatePrepareEditableTree( props ) {
		return ( formats, text ) => {
			if ( ! props.isEnabled ) {
				return formats;
			}

			const search = 'Gutenberg';
			const index = text.indexOf( search );

			if ( index === -1 ) {
				return formats;
			}

			const start = index;
			const end = index + search.length;

			const newValue = wp.richText.applyFormat( { text, formats }, { type: 'plugin/annotation' }, start, end );

			return newValue.formats;
		};
	},
} );

How has this been tested?

Any reason not to pass the entire value?

Yes. We don't want to alter the text at this stage. Otherwise the internal value is wrong. This should be purely for applying formatting on top of text.

We could also pass the entire value and only use the formats from what is returned. Also maybe warn if the length is different.

This feels like a great start, can we try to polish the PR for merge.

Also, I'm wondering if we should keep prepareEditableTree as experimental API for some time. Thoughts? Like just rename it __experimentalPrepareEditableTree?

Yes, it was actually wrong before. We're expecting a padded multiline element.

We are generating a new array here on each render, I wonder if this is the source of the rerendering happening in all RichText. I wonder if we could memoize it somehow in withSelect by using settings.__experimentalGetPropsForEditableTreePreparation( sel ) as the memoization key, as we don't want to generate a new array if the the returned value didn't change.

Anyway, it doesn't feel unsolvable, so for the sake of iterations, I'm fine leaving this optimisation for a follow-up.

Could it also be creating a new object in withSelect every time? But sure, sounds resolvable.

Should we create an issue for this one?

LGTM 👍

Do you want to give it another look @aduth?

Ideally this is followed up with some tests and a Christmas light investigation.

I think you can simplify it to:

return withSelect( ( select, ownProps ) => ( {
	prepareEditableTree: [
		...ownProps.prepareEditableTree,
		settings.__experimentalCreatePrepareEditableTree( settings.__experimentalGetPropsForEditableTreePreparation( select ) ),
	],
} ) )( OriginalComponent );

Updated: I thought settings.__experimentalGetPropsForEditableTreePreparation returns a boolean value.

It still has this issue that it will create a new reference each time props change.

☝️ this way you will have only one wrapping HOC instead of two.

I tried this, it doesn't behave exactly the same.

I have no idea tbh. But now this is true, where it wasn't before: "Quote can be converted to paragraphs and renders a void paragraph if both the cite and quote are void".

This worries me that our standard set of operations for a single input have suddenly become more non-performant. Am I wrong to be worried?

The only thing that changes the difference between the created DOM tree by us will be applied to the live DOM. With most input, there will be no changes.

Before 4.3 I'd hope.
