`joinToString` has `truncated: CharSequence = "......

# stdlib

[maxmello]

joinToString has truncated: CharSequence = "..." as an optional parameter. It would be nice if String.take(n: Int) could have the same optional parameter that is appended in case n is smaller than the length of the String. Maybe it could also be a different method name, as this would be more a use case for logging/displaying a string similar to joinToString, rather than “working on a string” by using substring for maybe some logical operation on the string. It could be something like abbreviate or maybe cut

would you expect

"foo bar".take(7, truncated="...") == "foo bar"
"foo bar".take(6, truncated="...") == "foo ba..."

or

"foo bar".take(7, truncated="...") == "foo ..."
"foo bar".take(6, truncated="...") == "foo..."

?

I would expect the first. Basically the same logic as if I would to “foo bar”.toCharArray().joinToString(“”, limit = 6, truncated=“…”). Maybe the parameter name could imply that it is appended in addition to the specified limit, like truncatedAppend or so
