Use raw literal for string formatting (#46) When formatting strings, avoid using strconv.Quote if the string looks like it has already been escaped. Instead, use a raw string literal by wrapping the string with '`' characters if possible. For now, we still use strconv.Quote if the input string contains newlines to maintain the property that Format outputs a single line. Also, prefix strings obtained by the Stringer.String method with a 's'. This allows users to more easily distinguish when an output really is of type string or if the String method was used.
This package is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal.
The primary features of cmp are:
When the default behavior of equality does not suit the needs of the test, custom equality functions can override the equality operation. For example, an equality function may report floats as equal so long as they are within some tolerance of each other.
Types that have an Equal method may use that method to determine equality. This allows package authors to determine the equality operation for the types that they define.
If no custom equality functions are used and no Equal method is defined, equality is determined by recursively comparing the primitive kinds on both values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported fields are not compared by default; they result in panics unless suppressed by using an Ignore option (see cmpopts.IgnoreUnexported) or explictly compared using the AllowUnexported option.
