Config

Yaml.Config class to manage Yaml configuration files and provide a Yaml.Root node.

Yaml.Config use a Yaml.Finder to easily retriew a particular node.
The Yaml.Config.get method is bind to the Yaml.Finder.find method with
the root node as context. (more details on Yaml.Finder)

 var config = new Yaml.Config (path);
 var node   = config.get ("ship-to.address.city{0}");
 if (node != null) {
     of.echo (node.data)
 }

You can use a special import clause to embed a set of yaml files into your current document.

# |  use special key word '^imports' to import other yaml config files in 
# |  current yaml document
# |  '^imports' must be uniq and a direct child of root node
# |  imported files are injected as mapping nodes at top document level
# |  so you cannot use keys that already exists in the document
^imports :
   # you can redefine default import path with the special key '^path'
   # if you do not use it, the default path value will be the current directory
   # redefined path values are relative to the current directory (if a relative path 
   # is provided)
   ^path : ./config
   # you can also define any other var by prefixing key with ^
   ^dir  : subdir
   # and use it enclosed by ^
   # here final test path will be "./config/subdir/test.yml"
   test  : ^dir^/test.yml 
   # here final db path will be "./config/db.yml"
   db    : db.yml
