OptionCollection no longer yields duplicate keys as an array, but instead yields each key in turn.
For example, given an INI file:
[test] a = 1 a = 2 b = 3
IniParse would previously yield a single "a" key: an array containing two
Lines:doc['test'].map { |line| line } # => [[<a = 1>, <a = 2>], <b = 3>]
Instead, each key/value pair will be yielded in turn:
doc['test'].map { |line| line } # => [<a = 1>, <a = 2>, <b = 3>]
Directly accessing values via
[]will still return an array of values as before:doc['test']['a'] # => [1, 2]
-
LineCollection#each may be called without a block, returning an Enumerator.
doc = IniParse.parse(<<~EOF) [test] a = x b = y EOF doc[test].each # => #<Enumerator: ...>
This allows for chaining as in the standard library:
doc['test'].map.with_index { |a, i| { index: i, value: a.value } } # => [{ index: 0, value: 'x' }, { index: 1, value: 'y' }]
