Is there any function in std library to partition a string into Pair. I wanted to created pair from a property string. What i am doing right now is,

val tuple = "key=value".split("=")
val pair =  when {
                  tuple.size > 1 -> tuple[0] to tuple[1]
                  else -> tuple[0] to ""
               }

suresh: What I could come up with:

val tuple = "key=value".splitToSequence("=")
val pair = (tuple + generateSequence { "" }).take(2).toList()

Actually, that produces a list, not a pair. Hm.

How about this?

val tuple = "key=value".split("=") + ""
val pair = tuple[0] to tuple[1]

that is way better 😄

Got the idea from your sample 😄

tuple[1] will throw if there is no = in the string missed +"" sorry
