back-$ref's in a referenced file no longer resolve in speccy 0.8.x

[devjack]

If openapi.yml $ref's otherfile.yml, $ref's in otherfile.yml do not resolve.

Detailed description

To reproduce, I ran speccy 0.7.3 and 0.8.4 over the same Open API definition.

This screenshot shows that speccy 0.7.3 resolves the $ref from ping.yml to openapi.yml and 0.8.4 does not (it produces an empty object instead).

Context

I define each URL/verb combination as an endpoint and all responses as JSON Schema and use speccy to combine/resolve between the relevant files and formats. An example of this usage is in this example Open API definition (see the npm scripts for speccy cli usage).

Example

File: openapi.yml

...
paths:
    /ping:
       $ref: "endpoints/ping.yml#/paths/~1ping"

...

components:
    schemas:
        ping:
            $ref: 'schemas/ping.json'
...

File: endpoint/ping.yml

paths:
    '/ping':
        get:
          responses:
            '200':
              content:
                application/json:
                    schema:
                        $ref: '../openapi.yml#/components/schemas/ping'

Environment

• Node Version: v8.9.4
• OS: MacOS 10.13.4
• Link to your project: Reproduced in this example Open API definition.

I've verified that the bug was introduced between 0.7.3 and 0.8.0, likely (?) with the introduction of oas-kit.

@devjack looks like Mike is helping you out over on oas-kit. How's it going?
