Class
YAML::Store
provides the same functionality as PStore
, except it uses YAML to dump objects instead of Marshal
.
Example
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

@opt.update(o.pop)
end
super(*o)
end
Creates a new YAML::Store
object, which will store data in file_name
. If the file does not already exist, it will be created.
YAML::Store
objects are always reentrant. But if thread_safe is set to true, then it will become thread-safe at the cost of a minor performance hit.
Options passed in through yaml_opts
will be used when converting the store to YAML via Hash#to_yaml()
.
