regex - Splitting a string into words and punctuation with Ruby -

-

i'm working in ruby , want split string , punctuation array, want consider apostrophes , hyphens parts of words. example, 

s = "here...is     happy-go-lucky string i'm writing"

should become 

["here", "...", "is", "a", "happy-go-lucky", "string", "that", "i'm", "writing"].

the closest i've gotten still inadequate because doesn't consider hyphens , apostrophes part of word.

this closest i've gotten far: 

s.scan(/\w+|\w+/).select {|x| x.match(/\s/)}

which yields 

["here", "...", "is", "a", "happy", "-", "go", "-", "lucky", "string", "that", "i", "'", "m", "writing"]

.

you can try following:

s.scan(/[\w'-]+|[[:punct:]]+/) #=> ["here", "...", "is", "a", "happy-go-lucky", "string", "that", "i'm", "writing"]
