Is there is a way to merge enums into one flat enum, or list?

See original GitHub issue

I am using the 2.0 spec and I have a field which I am using in a model as well as a path param where the value can be from one of three different enums. Using the syntax below is turning into an array with 3 enums. However, I would like it to be one flat enum. Is there any way to achieve this?

Thanks so much:

    properties:
      type:
        type: "string"
        enum: 
        - *unitTypes
        - *componentTypes
        - *snootTypes

YAML does not support this.

where the value can be from one of three different enums.

In OpenAPI 3.0 this can probably be handled using oneOf:

components:
  schemas:
    Colors1:
      type: string
      enum: [red, green, blue]
    Colors2:
      type: string
      enum: [black, white]
    
    Color:
      oneOf:
        - $ref: '#/components/schemas/Colors1'
        - $ref: '#/components/schemas/Colors2'

can I also use this for my path param?

Yes. In 3.0, all parameters use a schema, so the syntax would be similar to models:

- in: path
  name: color
  required: true
  schema:
    oneOf:
      - $ref: '#/components/schemas/Colors1'
      - $ref: '#/components/schemas/Colors2'

I’m assuming there is no way to do this in OpenAPI 2.0?

Correct. oneOf is a new feature in 3.0.
