Add possibility to specify location when you pass object

[IvanGoncharov]

If you pass object it's impossible to resolve external relative references.
It would be cool if I can add option where I can specify base path for relative refs.

I like this idea. Will add it soon

My current workaround is to just change working directory with process.chdir before resolving, then changing it back afterwards.

+1. @BigstickCarpet Any progress on this?

[alvassin]

@litek workaround with changing working directory will not work if you deal with URLs (referenced issue).

[JamesMessinger]

alright. I'll get this knocked out this weekend

[JamesMessinger]

As of version 3.1.1, you can now pass a URL and an object to any method.

$RefParser.dereference("http://example.com/my-schema.json", mySchemaObject, {})

NOTE: As shown in the example above, you must also pass an options object (even an empty object will work), otherwise, the method signature looks like you're just passing a URL and options.

@BigstickCarpet thanks a lot for feature, but there is a bug: paths begin to duplicate (i pass dereferenced.raml file here, because schema is defined inside it and its path is relative to raml):

schema = {
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "properties": {
    "items": {
      "$ref": "schemas/item.json"
    }
  }
}

deferred = @q.defer()
require('json-schema-ref-parser').dereference(
    'test/raml-files/deferenced.raml', schema, {}
  )
  .then((dereferencedSchema) ->
    deferred.resolve(JSON.stringify(dereferencedSchema))
  )
  .catch((err) ->
    deferred.reject(err)
  )

I'll get following error:

Error: Error resolving $ref pointer "test/raml-files/test/raml-files/schemas/item.json".
"test/raml-files/test/raml-files/schemas/item.json" not found.

Path seems to be duplicated here.

@alvassin - Good catch. I had forgotten to account for relative URLs. In all my tests, I was passing absolute URLs. Anyway, it's fixed now. Try the latest version

@BigstickCarpet yeeeah! it works! thanks for super-fast fix, much appreciated 🍺
