Rails 7 adds Pathname#existence

Rails 7 introduces Pathname#existence method, which returns the receiver if the given file path exists, otherwise returns nil.

We need to first check whether the given file path exists or not to perform any other operations on it.

=> file_path = "config/schedule.yml"
=> Pathname.new(file_path).read if Pathname.new(file_path).exist?

The Pathname#existence method acts like Object#presence for file existence.

=> file_path = "config/schedule.yml"
=> Pathname.new(file_path).existence&.read
