Status changed from Open to Closed With recent commits to the master branch, keyword splats of empty hashes do not pass positional arguments to methods or cause an empty hash to be added to an array. ---------------------------------------- Bug #11860: Double splat does not work on empty hash assigned via variable https://bugs.ruby-lang.org/issues/11860#change-81363 * Author: sawa (Tsuyoshi Sawada) * Status: Closed * Priority: Normal * Assignee: * Target version: * ruby -v: 2.3.0preview2 (2015-12-11 trunk 53028) [x86_64-linux] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN ---------------------------------------- When an empty hash is given as a literal, the double splat operates on it, and leaves nothing, which is expected. ```ruby class String def foo; end end [**{}] # => [] "foo".foo(**{}) # => nil "foo".send("foo", **{}) # => nil ``` However, when an empty hash is given via variable, the double splat retains an empty hash in place. ```ruby h = {} [**h] # => [{}] "foo".foo(**h) # => wrong number of arguments (given 1, expected 0) "foo".send("foo", **h) # => wrong number of arguments (given 1, expected 0) ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
