New SimplePlugin: InheritKeywords

[elbakerino]

A plugin that uses parentSchema to inject some keywords, when existing in parentSchema, to the child schema.

This makes it possible for nested schema-levels to inherit some (configurable?) keywords.

• readOnly is the best example
• hideTitle/hidden must be checked, may conflict with props overrides
• ?

Proposed:

const InheritKeywords = (keywords: string[]) => ({
    should: () => true,
    handle: ({ errors, valid, parentSchema, schema }: any) => {
        let newSchema = schema

        if (parentSchema) {
            keywords.forEach(keyword => {
                let foundKeyword = parentSchema.get(keyword)
                if (foundKeyword !== undefined) {
                    newSchema = newSchema.set(keyword, foundKeyword)

                }
            });
        }
        return { schema: newSchema }
    }
});

Usage:

export const getCustomWidgets: () => CustomWidgetsBinding = () => {

    return ({
        ...widgets,
        pluginSimpleStack: [
            ...widgets.pluginSimpleStack,
            InheritKeywords(['readOnly'])
        ]
    })
}
