Ruby gem to extend Hash and Array with filters for blank, empty, and nil values. This module creates new methods to be prepended to the Array, Hash, String, and Object classes to implement recursive filters for blank, empty, and nil values. The methods can select or reject values which are blank (whitespace), empty (zero length), or nil, and do so recursively. The default behavior is to filter recursively, without limit. However, optional arguments may be applied to any filter method to indicate the start level and the depth to which filtering should be done. This is useful if, say, a hash needs to retain its top-level keys, regardless of whether or not its values are empty, but deeper level hashes can be completely removed if they are empty. Note: ActiveSupport provides some of these methods, but in general is a much larger body of code. This module are only those methods related to "blank", "empty" or nil. Also, ActiveSupport uses Regexp match to determine blankness, while this code uses a non-destructive strip, which is both faster and less sensitive to non-UTF8 string error conditions. In general an empty value has zero length, and a blank value is either empty or has all blank values (e.g., to_s.strip.length.zero?). In the descriptions below, aoh is an Array or Hash object.
