Method caller in ruby

30 Jan 2019

Python has this by default, a function that receives a method and arguments and return a function that when called with an object call the method with the provided args. Perfect for usign with map and reduce family of fuctions.

Here is how to achieve the same with ruby

def methodcaller(method, *args)
  ->(object) { object.send(method, *args) }
end

['foo', 'boo', 'zoo'].map(&methodcaller(:gsub, 'oo', 'aa'))

Cheers
