Missing description comment on referenced type

[hborchardt]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

I am using typeconv to convert the following JSONSchema to TypeScript. Unfortunately the description is not converted into a comment when the type of a property is not a primitive but a reference to another property in the schema.

{
  "type" : "object",
  "additionalProperties" : false,
  "properties" : {
    "a" : {
      "$ref" : "#/definitions/A"
    }
  },
  "definitions" : {
    "B" : {
      "type" : "object",
      "additionalProperties" : false,
      "properties" : {
        "_id" : {
          "type" : "string"
        }
      },
      "required" : [ ]
    },
    "A" : {
      "type" : "object",
      "additionalProperties" : false,
      "properties" : {
        "_id" : {
          "description": "niice",
          "type" : "string"
        },
        "b" : {
          "description": "nice",
          "$ref" : "#/definitions/B"
        }
      },
      "required" : [ ]
    }
  }
}

Observed output after typeconv -f jsc -t ts a.json: (note the missing comment on property b)

export interface B {
    "_id"?: string;
}

export interface A {
    /** niice */
    "_id"?: string;
    b?: B;
}

Expected output:

export interface B {
    "_id"?: string;
}

export interface A {
    /** niice */
    "_id"?: string;
    /** nice */
    b?: B;
}

Here is the diff that solved my problem:
