Yew

Yew allows traversing a Hash structure as if it is an object tree.

Usage

Given the following yml file located at config/env.yml:

orientdb:
  url: 'remote:localhost/db'
  user: admin
  pass: secret

testing:
  frameworks:
    minitest: true
    rspec: false

Load the YAML structure.

Env = Yew::Tree.new(YAML.load(File.read('config/env.yml')))

If you prefer, there's a shortcut method: Yew.load

Env = Yew.load('config/env.yml')

Traverse the structure contents.
```
Env.orientdb.user
# => 'admin'
```

Obtain the underlying Hash.

Env.testing.frameworks[]
# => {"rspec"=>false, "minitest"=>true}

A tree can also be traversed like a normal Hash.

Env['orientdb']['user']
# => 'admin'

Env['orientdb'].user
# => 'admin'

It raises well formed errors when accessing inexistent paths.

Env['orientdb'].timeout
# => RuntimeError: Attribute timeout not found at /orientdb

Set $YEW_DEBUG when need to inspect Yew::Tree objects under irb.
```
irb> $YEW_DEBUG = true
irb> require 'yew'
```

Installation

There are two options for installation: packaged gem and as source file.

Install Yew as a gem.
```
gem install yew
```

Download raw lib into a project source tree.

curl "https://raw.github.com/snmgian/yew/master/lib/yew.rb" 2>/dev/null -o "yew.rb"
