ruby - Lossy Split and Join Expression -


i'm using split(/ /) method, after join them ending white spaces gone.

the string matched against this:

"word word  word  "

the array returned split(/ /) this:

["word", " ", "word", " ", " ", "word"]

i expected this:

["word", " ", "word", " ", " ", "word", " ", " "]

this should work you

str.scan(/\w+| /)

this example

2.2.1 :003 > "word word word ".scan(/\w+| /)
=> ["word", " ", "word", " ", " ", "word", " "]
