In Ruby, is there an Array method that combines 'select' and 'map'?

Question

I have a Ruby array containing some string values. I need to:

1. Find all elements that match some predicate
2. Run the matching elements through a transfo

Answer 1

I'm not sure there is one. The Enumerable module, which adds select and map, doesn't show one.

You'd be required to pass in two blocks to the select_and_transform method, which would be a bit unintuitive IMHO.

Obviously, you could just chain them together, which is more readable:

transformed_list = lines.select{|line| ...}.map{|line| ... }
