LoadFile

Load/Overload YAML/JSON file(s) into desired constant.

Installation

Add this line to your application's Gemfile:

gem "load_file"

Usage

LoadFile.load(file: "examples/.travis.yml", constant: :TravisConfig)

# now you can access TravisConfig for configs in examples/.travis.yml
TravisConfig
=> {"sudo"=>false, "language"=>"ruby", "cache"=>"bundler", "rvm"=>["2.5.1"]}

LoadFile.load(file: "examples/app.json", constant: :HerokuApp)

# now you can access HerokuApp for configs in examples/app.json
HerokuApp
=> {"name"=>"Small Sharp Tool",
  ...
  "environments"=>{"test"=>{"scripts"=>{"test"=>"bundle exec rake test"}}}}

You can also load into a namespaced constant:

LoadFile.load(file: "examples/app.json", constant: :App, namespace: Heroku)

# Heroku::App will be the hash loaded from examples/app.json

The caveat here is the keyword argument namespace must be a ruby object.

Or should I introduce constantize? Please let me know.

What if I want to override existing constant?

Use overload APIs.
