words breaks a string up into a list of words, which were delimited by white space (as defined by isSpace). This function trims any white spaces at the beginning and at the end.

Examples

>>> words "Lorem ipsum\ndolor"
["Lorem","ipsum","dolor"]

>>> words " foo bar "
["foo","bar"]

unwords joins words with separating spaces (U+0020 SPACE). unwords is neither left nor right inverse of words:

>>> words (unwords [" "])
[]

>>> unwords (words "foo\nbar")
"foo bar"

Examples

>>> unwords ["Lorem", "ipsum", "dolor"]
"Lorem ipsum dolor"

>>> unwords ["foo", "bar", "", "baz"]
"foo bar  baz"
