class Hash

Monkey patch hash to provide pathify method

Public Instance Methods

pathify(sep = '/', paths = [], path = '') click to toggle source

Returns a flat hash that show the full path to the value, so we don't have to recursively traverse a nested hash Examples:

> {foo: 'ff'}.pathify¶ ↑

=> {foo: 'ff'}

> {foo: {bar: 'gg', boo: 'hh'}}.pathify¶ ↑

=> {'foo/bar': 'gg', 'foo/boo': 'hh'}

Optionally, Specify a seperator as first argument (defaults to '/')
