Golang：按照源代码中的显示方式打印结构

Question

Similar to this question but not quite identical.

I'm doing some code-generation, making .go files from within Go. I've got a struct, and I want to generate the text representation of it so that I can insert it as a literal into the generated code.

So, if I had myVal := SomeStruct{foo : 1, bar : 2}, I want to get the string "SomeStruct{foo : 1, bar : 2}".

Is this possible in Go?

From the fmt package:

%#v   a Go-syntax representation of the value

This is as close as you can come with built-in formatting, after removing the package identifier (main. in this example) from the output.

type T struct {
    A string
    B []byte
}

fmt.Printf("%#v
", &T{A: "hello", B: []byte("world")})

// out
// &main.T{A:"hello", B:[]uint8{0x77, 0x6f, 0x72, 0x6c, 0x64}}
