Description

String#each_chunk iterates chunks of specified size in String.
String#chunks is a shorthand for str.each_chunk(n).to_a.

present:

str = <<EOS
20190101 20190102
20190103 20190104
EOS

str.scan(/.{1,9}/m) do |chunk|
  p chunk #=> "20190101 "
end

str.scan(/.{1,9}/m) do |chunk|
  chunk.strip!
  p chunk #=> "20190101"
end

str.scan(/.{1,9}/m) #=> ["20190101 ", "20190102\n", "20190103 ", "20190104\n"]
str.scan(/.{1,9}/m).map(&:strip) #=> ["20190101", "20190102", "20190103", "20190104"]

proposal:

str = <<EOS
20190101 20190102
20190103 20190104
EOS

str.each_chunk(9) do |chunk|
  p chunk #=> "20190101 "
end

str.each_chunk(9, strip: true) do |chunk|
  p chunk #=> "20190101"
end

str.chunks(9) #=> ["20190101 ", "20190102\n", "20190103 ", "20190104\n"]
str.chunks(9, strip: true) #=> ["20190101", "20190102", "20190103", "20190104"]
