Php's chunk_split alternative in ruby

Ruby
1

hello,
how could I chunk_split string

mylongstring = “some long long long string”

into smaller strings of length 3.

In PHP it is

chunk_split(mylongstring,3);

What is it in ruby?

Thank you in advance!

Like that? If not, you’ll need to give an example of the output you’re
trying to achieve (which is generally a good idea anyway…).

Exactly like that :slight_smile:

Ah, do not forget, in ruby land, you can be flexible :slight_smile:

C:\family\ruby>cat test.rb
class String
alias old_split split
def split arg1=’ ', *args
case arg1
when Integer
self.scan(/.{1,#{arg1}}/)
else
old_split arg1, *args
end #case
end #def
end #class

p “this is a test string. okay?”.split
p “this is a test string. okay?”.split(/i/)
p “this is a test string. okay?”.split(3)

C:\family\ruby>ruby test.rb
[“this”, “is”, “a”, “test”, “string.”, “okay?”]
[“th”, "s “, “s a test str”, “ng. okay?”]
[“thi”, “s i”, “s a”, " te”, "st ", “str”, “ing”, “. o”, “kay”, “?”]

Is that ok?
