pretty.go

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.
