Usage

$ref

Includes a single-level of swagger file.

Official standards
Recommended, universal

For yaml example:

$ref: "./host.yaml"
parameters:
  - $ref: "name.yaml"
  - $ref: "./year.yaml"
  - $ref: "age.yaml#/alex/son"
remote:
  $ref: "https://raw.githubusercontent.com/WindomZ/swagger-merger/remote.yaml#/name"
responses:
  $ref: "./responses.yaml#/post"

$ref#*

Includes a multi-level of swagger file.

Non-standard, suggest you use it for yourself
Instead of $ref, can be used side by side and not an array

For yaml example:

paths:
  $ref#pets: "./paths/pets.yaml"
  $ref#pets-id: "./paths/pets-id.yaml"
paths-url:
  $ref#paths: "https://raw.githubusercontent.com/WindomZ/swagger-merger/master/test/no_ext_json"

Output yaml:

paths:
  /pets:
    hello: world
  /pets/{id}:
    good: bye
paths-url:
  /pets:
    hello: world
  /pets/{id}:
    good: bye

A way of using $ref instead of $ref#*, and better compatibility.
