words package:xmonad-contrib

words breaks a string up into a list of words, which were delimited by white space.

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

unwords is an inverse operation to words. It joins words with separating spaces.

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

Join words with spaces, and wrap the result in delimiters unless there was exactly one element.

Examples

>>> wrapUnwords "{" "}" ["A", "B"]
"{A B}"

>>> wrapUnwords "{" "}" ["A"]
"A"

>>> wrapUnwords "{" "}" []
""
