fmt.Printf Go-syntax formated representation of the value

[Jérôme LAFORGE]

Hello,

In my unit tests when expected is not the actual result, I like display actual value with Go-syntax. For example:

if got != expected {

     t.Errorf(" %#v", got) // []string{"blah','blah"}

}

But it want to know if there is elegant way to display as formatted on multi-lines (a kind of indented json but with gofmt rules)?

Thanks in advance,

[Dan Kortschak]

There are a bunch of pretty printers. I use github.com/kortschak/utter
which renders as Go syntax where possible. Another that attempts to do
the same thing with slightly different priorities is
github.com/jba/printsrc.
