Description

I did:

require 'pathname'
module PathRefinement

  refine Pathname do

    def to_s
     '"%s"' % self 
    end
  end

end


module Builder

  using PathRefinement


  def call(s,params)
    cmd = s % params
    puts cmd
    system(cmd)
  end

  module_function :call
end

file = Pathname($0).expand_path

Builder.call("cat %s", file)

I got:

C:\Users\Dominic E Sisneros\source\repos\ruby\refine_pathname>ruby system_refinement.rb
cat C:/Users/Dominic E Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb
cat: 'C:/Users/Dominic': No such file or directory
cat: E: No such file or directory
cat: Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb: No such file or directory

I expected:

cat \"C:/Users/Dominic E Sisneros/source/repos/ruby/refine_pathname/system_refinement.rb\"

because format %s is supposed to call to_s.

  • Backport deleted (2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN)
  • Tracker changed from Bug to Feature

This isn't a bug, as it is currently expected that refinements would not be used in this case. Switching this to a feature request.
