Issue #11925 has been updated by Herwin Quarantainenet. What about `new_from_kwargs(**kwargs)` ? It's a bit long, but it describes the functionality exactly. ---------------------------------------- Feature #11925: Struct construction with kwargs https://bugs.ruby-lang.org/issues/11925#change-61064 * Author: Ilya Vorontsov * Status: Open * Priority: Normal * Assignee: ---------------------------------------- Propose to make Struct subclass constructors which accept keyword arguments. Not sure, if it's reasonable to allow `.new` accept kwargs, so may be should use different method named like `.create`: ```ruby Point = Struct.new(:x,:y, :color) pt_1 = Point.create(x: 1, y: 2) # => Point<x: 1, y: 2, color: nil> pt_2 = Point.create!(x: 1, y: 2) # => ArgumentError, color not specified. ``` It will greatly simplify work with big structures, especially in cases when struct layout changes and for cases when structure can have lots of non-significant values. It also allows simpler ways to use implement default values for struct members. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
