Functions

func String

func String(s string, maxLength int) string

String truncates long strings from the middle, but leaves strings shorter than `maxLength` untouched. If the string is shorter than the string "-(truncated)" and the string exceeds `maxLength`, the output will not be truncated. Example:

truncate.String(strings.Repeat("a", 25), 20) == "aaaaaaaa-(truncated)"
truncate.String("foobar", 20) == "foobar"
truncate.String("foobar", 5) == "foobar"

func Value

func Value(v interface{}, maxLength int) interface{}

Value recursively walks through the value provided by `v` and truncates any strings longer than `maxLength`. Example:

	 type foobar struct{A string; B string}
  truncate.Value(foobar{A:"foo",B:"bar"}, 20) == foobar{A:"foo",B:"bar"}
  truncate.Value(foobar{A:strings.Repeat("a", 25),B:"bar"}, 20) == foobar{A:"aaaaaaaa-(truncated)",B:"bar"}
