Module: Plist::Emit

Included in:
Array, Hash
Defined in:
lib/ultra_pow_list/vendor/ruby1.9/plist/plist/generator.rb

Overview

Create a plist

You can dump an object to a plist in one of two ways:

  • Plist::Emit.dump(obj)

  • obj.to_plist

    • This requires that you mixin the Plist::Emit module, which is already done for Array and Hash.

The following Ruby classes are converted into native plist types:

Array, Bignum, Date, DateTime, Fixnum, Float, Hash, Integer, String, Symbol, Time, true, false

  • Array and Hash are both recursive; their elements will be converted into plist nodes inside the <array> and <dict> containers (respectively).

  • IO (and its descendants) and StringIO objects are read from and their contents placed in a <data> element.

  • User classes may implement to_plist_node to dictate how they should be serialized; otherwise the object will be passed to Marshal.dump and the result placed in a <data> element.

For detailed usage instructions, refer to USAGE and the methods documented below.

Class Method Details

.dump(obj, envelope = true) ⇒ Object

The following Ruby classes are converted into native plist types:

Array, Bignum, Date, DateTime, Fixnum, Float, Hash, Integer, String, Symbol, Time

Write us (via RubyForge) if you think another class can be coerced safely into one of the expected plist classes.

IO and StringIO objects are encoded and placed in <data> elements; other objects are Marshal.dump‘ed unless they implement to_plist_node.

The envelope parameters dictates whether or not the resultant plist fragment is wrapped in the normal XML/plist header and footer. Set it to false if you only want the fragment.

def self.dump(obj, envelope = true)
  output = plist_node(obj)

  output = wrap(output) if envelope

  return output
end

.save_plist(obj, filename) ⇒ Object

Writes the serialized object’s plist to the specified filename.
