YamlRefResolver

This is a gem that resolves and expands $ref references to other YAML files.

Installation

Just add this line to your application's Gemfile and run bundle install.

gem 'yaml_ref_resolver'

Assume that we have following yaml files.

# index.yaml
author:
  $ref: './john.yaml#/profile'

# john.yaml
profile:
  name: John
  age: 28

This gem resolves $ref references.

resolver = YamlRefResolver.new

hash = resolver.resolve!('index.yaml')
#=> {'author' => {'name' => "john", 'age' => 28}}

Optionally you can specify the key.

resolver = YamlRefResolver.new(key: '$import')

Give an entry point yaml with -i or --input option.

$ yaml_ref_resolver -i ./path/to/index.yaml

# dump to stdout

Optionally output file path with -o or --output can be given.

$ yaml_ref_resolver -i ./path/to/index.yaml -o ./path/to/output.yaml

-w or --watch option watches referenced yaml files and dump whole resolved yaml when one of them changed.

$ yaml_ref_resolver -i ./path/to/index.yaml -w

-j or --json switch outputs in json format instead of yaml format.

$ yaml_ref_resolver -i ./path/to/index.yaml -j
