Problem/Motivation

Following ✨ [2.0.0-alpha3] EnumPropType: Labelled enumerations Fixed and the introduction of meta:enum

We need to cover this syntax too: 

props:
  type: object
  properties:
    position:
      anyOf:
        - { "const": "top", "title": "Top"}
        - { "const": "bottom", "title": "Secondary"}

A bit more verbose and complicated, but JSON schema native and compliant.

Proposed resolution

We can do it in SchemaManager/Canonicalizer

If anyOfof oneOfis found, and every value is a const or an enum with only one item

, we transform it to:

{
      "type": ["string", "number", "integer"],
      "enum": [...],
      "meta:enum": {...}
}

However, we may need to split Canonicalizer::canonicalize() into 2 public methods:

  • one used for prop loading, with resolveQuirks(), the $schema["type"] = "integer" issue, and the "anyOF + const" we wnat to add. The changes to the schema are "persistent".
  • one used only for the compatibility checker. The changes to the schema are "volatile".
