golang tool for splitting long lines

[Sankar]

Hi

In Javascript world I have this handy tool Prettier which will automatically, reproducibly break long lines of code into multiple lines (and also merge parameters into a single line if some elements are removed). 

Are there similar tools available for Golang ? Either as a standalone program or as VSCode/Goland plugins.

From https://github.com/golang/go/issues/11915 I believe that go team may not address it as natively as gofmt/goimports. But are there any other hacks/tools that people already use to break long lines ? 

Thanks.

Hi Sankar,

Not really, a easy trick is to use json.MarshalIndent. It helped me a lot :)

playgound: https://play.golang.org/p/nfr2ANR6pPH

type A struct {
    A int
    B string
    C map[int]string
}

func main() {
    aa := A{
        A: 1,
        B: "2",
        C: map[int]string{3: "3"},
    }

    bs, _ := json.MarshalIndent(aa, "", "    ")
    fmt.Printf("%#v\n", aa)
    fmt.Println(string(bs))

}

I agree json.MarshalIndent is great. However, be aware that json.MarshalIndent will not output private (lowercase) fields of the struct.
