Module: TableSync::Utils

Defined in:
lib/table_sync/utils/proc_keywords_resolver.rb,
lib/table_sync/utils.rb

Overview

Problem:

> fn = proc { |first| puts first } > fn.call(:first, :second, :third) first

:second and :third was ignored. It’s ok.

> fn = proc { puts “test” } > fn.call(first: :first, second: :second, third: :third) test

And it’s ok.

> fn = proc { |&block| block.call } > fn.call(first: :first, second: :second, third: :third) { puts “test” } test

And this is ok too.

> fn = proc { |first:| puts first } > fn.call(first: :first, second: :second, third: :third) ArgumentError (unknown keywords: :second, :third)

¯_(ツ)_/¯

❤ Ruby ❤

Next code solve this problem for procs without word arguments, only keywords and block.
