Question

str = "This\n is a sample text for test"
str.scan(/\S.{0,15}\S(?=\s|$)|\S+/)
# => ["This", "is a sample text", "for test"]

Here, it splits when the newline (\n) is present. I actually want the output as,

 ["This\n is a", "sample text for", "test"]

How can I achieve that?

Answer 1

Use the /m modifier which allows the dot to match newlines:

str.scan(/\S.{0,15}\S(?=\s|\z)|\S+/m)

Also, I suggest you use \z instead of $ because $ matches the end of a line; \z is the only way to force Ruby to match the end of the string. It doesn’t matter in this example, but it’s a good habit to get into. Ruby differs from all other regex flavors in these two points.
