HashGraft¶ ↑
Hash/Array Mixins¶ ↑
adds get_path(path) and set_path(path, value) to Hash
. Allows to traverse deeply nested data structures similar to structures.
Arrays also validate a wildcard “*”.
@example_1 = { "guys" => [ {"name" => "Dean"}, {"name" => "Sal"}, {"name" => "Carlo"}, ], "gals" => [ {"name" => "Marylou"}, {"name" => "Camilly"}, {"name" => "Terry"}, {"name" => "Mary"}, {"name" => "Rita"}, {"name" => "Amy"}, ]} @example_1.get_path "gals/2/name" # => "Terry" @example_1.get_path("gals/*/name") # => ["Marylou","Camilly","Terry","Mary","Rita","Amy"] @example_1.graft(@example_1) # => nothing changes
Transformer¶ ↑
uses get_path/set_path to transform one data structure into another. examples will follow
