Prevent formatter from panic'ing with unexported fields This is not by any means a fix, but a real fix would require cloning much of print.go from fmt.
Package pretty provides pretty-printing for go values. This is useful during debugging, to avoid wrapping long output lines in the terminal.
It provides a function, Formatter, that can be used with any function that accepts a format string. For example,
type LongTypeName struct {
longFieldName, otherLongFieldName int
}
func TestFoo(t *testing.T) {
var x []LongTypeName{{1, 2}, {3, 4}, {5, 6}}
t.Errorf("%# v", Formatter(x))
}
This package also provides a convenience wrapper for each function in package fmt that takes a format string.
