Unwraps shared block style variations.
Description
It takes the shared variations (styles.variations.variationName) and applies them to all the blocks that have the given variation registered (styles.blocks.blockType.variations.variationName).
For example, given the core/paragraph and core/group blocks have registered the section-a style variation, and given the following input:
{ “styles”: { “variations”: { “section-a”: { “color”: { “background”: “backgroundColor” } } } } }
It returns the following output:
{ “styles”: { “blocks”: { “core/paragraph”: { “variations”: { “section-a”: { “color”: { “background”: “backgroundColor” } } }, }, “core/group”: { “variations”: { “section-a”: { “color”: { “background”: “backgroundColor” } } } } } } }
Parameters
