PStore
YAML::Store provides the same functionality as PStore, except it uses YAML to dump objects instead of Marshal.
require 'yaml/store' Person = Struct.new :first_name, :last_name people = [Person.new("Bob", "Smith"), Person.new("Mary", "Johnson")] store = YAML::Store.new "test.store" store.transaction do store["people"] = people store["greeting"] = { "hello" => "world" } end
After running the above code, the contents of “test.store” will be:
--- people: - !ruby/struct:Person first_name: Bob last_name: Smith - !ruby/struct:Person first_name: Mary last_name: Johnson greeting: hello: world
Creates a new YAML::Store object, which will store
data in file_name
. If the file does not already exist, it will
be created.
Options passed in through yaml_opts
will be used when
converting the store to YAML via Hash#to_yaml().
# File yaml/store.rb, line 49 def initialize( *o ) @opt = {} if String === o.first super(o.shift) end if o.last.is_a? Hash @opt.update(o.pop) end end
